DIY garden screw press. DIY apple press. Steel wine press

A large apple harvest sometimes becomes a problem for owners. The fruits cannot be stored for a long time; it is not always possible to sell them or prepare them for animal feed. The way out of the situation is homemade preparations in the form of jam and juices. It will be easier to prepare them if you use juicers and special homemade apple presses.

Juice presses are:

• Mechanical,
• Hydraulic,
• Pneumatic,
• Electrohydraulic.

Purchased models, regardless of type, cannot cope with large volumes of fruit.

Therefore, most gardeners prefer to make a household apple press with their own hands.

Each type has its pros and cons. Mechanical is less productive, but the easiest to manufacture. Hydraulic ones have a more complex mechanism, but are capable of producing high-quality fruit puree. A pneumatic device requires a compressor, this affects the price of the device. But it is capable of processing a large volume of fruit in a short time.

The most effective are electro-hydraulic models.

They operate on a combination of electricity and hydraulics. A person's job is only to serve fruit. The disadvantage of the device is the high cost of spare parts.

Most models provide pressure on the apple mass from above, but the combined version has its own differences:

• The screw device presses the mass from top to bottom,
• Hydraulic jack- down up.

To make a juice press you need to consider the following points:

• Juice container. You can use a tank or a large pan, and install a tap at the bottom to drain,
• If used wooden barrel, then it should be made of parquet slats,
• If a housing is used washing machine, then it must be clean and sealed, free of rust and mold,
• Apparatus body. The simplest option is a pyramid of wooden latticework.

To ensure uniform extraction of juice, finely chopped fruits are placed in clean bags, or transferred soft cloth. If this is not done, a DIY juice press will leave wet pulp and a large amount of waste. You can cut apples using an ordinary knife or a special chopper. The device can be purchased, but more often it is made independently and built into the pressing apparatus.

Homemade screw press

A properly assembled press can squeeze up to 70% of the juice from apples. The output remains dry pulp. The screw apparatus works by rotating large blades secured with nuts or jacks. The hydraulic jack design is more efficient and does not require the use of great physical force. Before making a press you need to prepare:

• Stanin,
• Housing for storing raw materials,
• Wooden gratings,
• Pressure piston
• Circle under the jack,
• Work unit,
• Tray or bowl.

For manufacturing, two metal pipes are taken, to which a profile is welded. Most often it is made in the form of a crossbar. A small hole is made in it, to which a threaded head is welded for installing a screw. A clamp is welded to the pipes or supporting structure. A handle for rotation is installed on top of the screw, and a stop at the bottom. It is a wooden or metal circle. Wooden body It is made of boards about 5 mm thick, they are tightened with self-tapping screws with an anti-corrosion coating. The distance between the yards should not exceed 1 cm. The strips with the yards are bent in the form of a circle and fastened with bolts. A plastic basin with a hole for draining juice is used as a tray.

Option using a jack

It is more convenient to use jacks for cars weighing 2-3 thousand kg instead of a screw. A nut for fastening is no longer required here, but homemade press the jack makes it more powerful. The only difference in the assembly is a durable frame that can withstand pressure. The jack is installed both from below and from above - it depends on the user’s preferences.

When the apparatus is ready, apples are placed in the container and a wooden circle is placed underneath. This will maintain the integrity of the structure at high pressure.

Average productivity - 1.75 liters of juice in 5 minutes.

How to make a hydraulic press

To make it you will need:

• Grinder machine,
• Welding machine,
• Capacity 50-60 l,
• Drill,
• Metal pipes with a wall thickness of 0.3 cm,
• Hydropress,
• Sturdy oak yards.

How to make a hydraulic press: drill a hole at the bottom of the tank and install a tap to drain the juice. The container is inserted into a barrel assembled from boards or slats. The distance between them should not be less than 0.3 cm. It is recommended to fasten the barrel with galvanized steel. If a barrel without a casing is used, then it is placed on a pallet. It has a hole for draining juice.

The base - the metal frame - must be strong, since it bears the main pressure. It is made according to the same principle as for a screw press. A DIY hydraulic press will become more stable if you weld 2-3 metal pipe sections to the bottom of the frame.

A circle made of wood can serve as a piston. The diameter should be slightly smaller than that of the juice container. It is made from two oak boards fastened with self-tapping screws. A circle of the same diameter made of stainless metal is usually used as a stop. The stop is installed hydraulic device.

An elastic barrel can also be used as a press. It connects to the water supply and will expand under the pressure of water. The press presses on the apples, resulting in the release of juice.

Homemade screw press

A screw press resembles a meat grinder. It works from electric motor, which rotates the pulley using a belt drive. Raw materials are loaded into the feed chamber, the auger crushes it and presses it through a sieve. At the output, the screw press produces juice with pulp.

For homemade this is the most difficult option. To assemble it, you will need drawings and diagrams, as well as:

• Durable stainless steel housing
• Screw press, which is placed inside the housing,
• Capacity for receiving raw materials,
• Container for prepared juice,
• Electric motor giving from 1500 rpm.

The structure is assembled on a metal frame. As a housing, you can use a housing from a regular or electric meat grinder. A screw press is installed in it, which is attached to the engine using a drive. A sieve with the required cell diameter is mounted on the outlet hole. You can use jars, pans or basins as containers for the finished juice.

The screw press has greater productivity because it is driven not by manual force, but by an electric motor.

The productivity of such a machine is up to 7 liters of juice in 5 minutes.

If you have experience making presses for apples and other fruits, share it in the comments to the article!

If you do not have a juicer on your farm, and every year at your dacha there is a large harvest of apples from which you need to make juice, then you need a mechanical press. A similar situation arises among wine lovers who do not want to manually crush juicy berries or trample them. Home craftsmen suggest making a press with your own hands for processing fruits. In this article we will look at how to make an apple press with your own hands.

Types and principles of operation of juice presses

Devices that are designed for juice production are divided into several types:

• mechanical devices;
• hydraulic units;
• electrohydraulic devices;
• pneumatic mechanisms.

Mechanical

The most common option is mechanical screw press. At first glance, you can understand the principle of operation of such a unit. Grapes, crushed fruits or berries are poured into the device’s container, which has holes. After this, by rotating the handle, a screw is activated, which lowers the flat piston. In this way, the juice is squeezed out and flows through the holes located in the casing into a tray, after which it enters prepared jars or other containers.

Important! To produce the casing, stainless steel is used or solid beech wood is used, from which the drainage version of the grate is made. The product consists of two halves, which are connected to each other by metal hoops.

Hydraulic

A modernized version of the mechanical unit is a manual hydraulic press for processing apples and grapes. It does not have a perforated container for separating juice. Instead, several drainage frames made of wood are used, between which bags with crushed raw materials are placed.

The manual version of the hydraulic jack is capable of developing a large force, corresponding to from 1 to 5 tons, due to which 70% of the juice of the volume of the initially placed fruit is obtained.

Important! The Grifon hydraulic press has in an original way refuse. It does not have a hydraulic jack. The developers have introduced a powerful “barrel” membrane. Pressure tap water at 1.5-2 atm. expands the membrane, due to which the juice is squeezed out through the wall of the casing, which is perforated.

Pneumatic

A pneumatic press operates on exactly the same principle. The fruit squeezing membrane is filling compressed air from the compressor, not water.

Important! All juice presses operate in combination with grinders. The most simple mechanism is a steel drum-grater, which is placed in a casing having a loading neck. When the handle rotates, the chopper operates, turning the fruit into very fine crumbs and pulp.

Electrohydraulic

A more advanced option is an electric drive mechanism. This device characterized by a minimum of physical effort and maximum productivity.

Which press should you choose?

Mechanical presses have a small productivity, which corresponds to 10-30 liters per hour. For processing berries, fruits and grapes grown on summer cottages, such equipment is quite enough, so you can easily make such a press for squeezing juice with your own hands.

To increase the quantity of juice produced and its quality, you can use two methods:

• use of container bags for crushed fruits;
• use of wooden drainage grates or stainless steel “pancakes”.

Important! Both options help improve the drainage of juice from the middle of the volume, which is compressed. The lack of drainage leads to the fact that the middle part of the crushed fruit is squeezed out much worse compared to the upper and lower layers. Additional positive thing The benefit of using bags is the ability to free the juice from the pulp.

If there are a large number of berries or fruits that need to be processed, an electric drive is used. In this case, two types of equipment are used:

• a traditional screw device, which is driven by an “electric motor-hydraulic jack” combination;
• a screw press that operates on the principle of a meat grinder.

A screw press juicer with an electric motor connected to it is used as a processing device for processing grapes, berries and tomatoes. The screw unit forces the crushed raw materials through a sieve, resulting in the formation of juice with big amount pulp.

Simple DIY grape press

Screw press for grape processing includes:

• base, the so-called frame;
• basket;
• a pressing device, the so-called jack or screw;
• pressing piston.

Important! There are other options for making the mechanism. During the manufacturing process of the device, you can use either pre-prepared sketches of the press or prepare your own drawings.

Materials and tools for making a press:

• Bulgarian;
• welding machine;
• tank 50 liters;
• drill;
• tap;
• metal channel with dimensions 10-12 mm - 150 mm;
• jack;
• metal corner having a size of 40-50 mm - 3200 mm;
• oak slats 40x25x400 mm in the amount of 50 pieces;
• a piece of fabric about one meter;
• fishing line 2 mm about 3 m.

Let's look at the process of making an apple press with your own hands.

Frame

The base is one of important elements a device that must have strength properties and be of a strong structure, since during operation the entire main load falls on the frame:

• For the side parts of the press we use metal corners height 85 mm.
• The upper and lower parts of the base are made of a metal channel, which has a length of about 70 cm.

For strength, you can use additional reinforcement of the structure by welding gussets between the corners and the channel, while welding all the joints together.

Important! If a screw press design is used, we weld a nut for the screw to the upper channel. In addition to the metal frame, you can also use wooden boards with a thickness of more than 5 cm. We secure the boards with 10-12 mm studs and tighten them with nuts. Wooden device It is much easier to manufacture than a metal unit, but a wooden structure is not able to withstand heavy loads. This press is quite suitable for small quantity raw materials. After manufacturing, the frame should be sanded and then painted with a special metal paint.

Press tank:

• For this design we use a cooking tank made of stainless steel with a volume of up to 50 liters.
• We drill a hole in the bottom of the container and install a stainless steel tap.

Important! If there is no tank, an ordinary saucepan of a suitable size is quite suitable.

• We insert a grate made of oak slats into the boiler container.
• For blanks we use oak or parquet board, the height of which corresponds to the height of the pan.
• At the ends of the slats along the edges we drill holes with a size of 2-3 mm, through which we stretch stainless wire or fishing line.
• By connecting all the planks together we get a structure that resembles a basket.

Important! During the manufacturing process, it is necessary to ensure that there is a gap of 2-3 mm between the slats, through which the juice from the prepared fruit will pass.

The design can be made without a pan:

• To do this, we connect the boards with galvanized steel boards and place the basket on a tray, which serves to drain the squeezed liquid.
• Also, as a tray in a juice press with your own hands, you can use a plastic tray for a large flower pot or kitchen sink made of stainless steel.
• There is a design option in which the grape press is made like a frame without a basket. Between the drainage grids, the pulp from the used fruit is laid out in several layers of fabric and pressed until juice is formed.

Piston:

1. Use a compass to draw a circle required diameter and use an electric jigsaw to cut out the remaining oak boards folded crosswise.
2. We twist the slats with stainless self-tapping screws or tie them together with stainless copper wire.

Important! You can also use a log, sawing off a circle of the required diameter and height.

Power mechanism

The apple processing press uses a screw or jack as a pressing mechanism.

Important! This design can also use a hydraulic car jack with a lifting capacity of 3 tons. For a better process, jacks are used that are capable of creating a force corresponding to 3 tons.

Every car enthusiast has a jack in his household, but a screw for a press is not so easy to find. It is necessary to cut planks for the jack, which will be used during the juice extraction procedure.

Filter cloth

To filter juice from apple fruits, you need to use a durable cloth that can allow moisture to pass through. The simplest option is to use a nylon sugar bag.

Important! For the filtration process, you can also use the following durable materials that can withstand heavy loads and not tear under pressure:

• lavsan;
• nylon;
• propylene;
• thick linen;
• durable cotton material.

Using a homemade press

A manual press for processing fruits with your own hands is ready for use, now let’s look at how the process of squeezing juice from prepared fruits occurs:

• We insert the basket into the tank and place the appropriate filter material inside.

Important! Soft berries, fruits and citrus fruits do not need pre-treatment before the crushing procedure. Carrots, apples or other hard fruits require crushing in a crusher or using pulp from a juicer, after which they are loaded into a basket and covered with a lid.

• We install the jack.
• We substitute the receiving container.
• Open the tap.
• We begin to press slowly.

Important! There is no need to use force or try to squeeze out all the juice at once, as the filter fabric may tear or the frame may be damaged. You need to make 2-3 pumps, wait for a while, then do 2-3 pumps again, and slowly squeeze out the juice.

If you use one bucket of apple pulp from a juicer, the result will be about 3-4 liters of pure juice; if you use crushed mass, you will get a slightly larger yield of the finished product.

Steel wine press

In order to make such a simple, at first glance, mechanism, you must have the skills of turning and plumbing and have welding machine.

How to make a steel grape press with your own hands:

• From an unnecessary washing unit from a stainless steel tank, we independently cut out two versions of cylindrical containers without a bottom, having a diameter of 23 cm and 29 cm. The height of the blanks corresponds to 24 cm.
• In the smaller cylinder we drill holes with a diameter of 8 mm in a checkerboard pattern.

Important! The inner container - a basket - is used to load grapes, and the outer one is used for juice.

• Under the cylinders we place a rectangular stainless steel tray with dimensions of 30x50 cm, which has sides and a triangular bevel in the narrow part of the product.
• We make a cutout in the outer cylinder to drain the juice.
• A flange with a diameter of 21 cm plays the role of a punch, which is attached in a rigid form to the lower section of the rod with a rectangular or trapezoidal thread. For this purpose, you can use a screw from a water valve. At the top we weld a head to the flange, which has a hole for the lever, thanks to which the thrust mechanism will function.

Important! To reduce the pressure on the sides of the press, it is recommended to perforate the thrust flange with a 4 mm drill.

• The nut, which is welded into the U-shaped frame, works together with the screw. The frame must be rigidly connected to the base; to do this, use screws to attach it to the table or concrete it into the floor.

Important! In order for the basket to be located in the central location of the outer container, bandage rings must be welded at the top and bottom of the basket.

Let's consider the process of functioning of a press for processing grapes made by yourself:

1. Place grapes in the inner pan.
2. Use the lever to tighten the screw.
3. When the squeezing process begins, rotate the screw more slowly, while controlling the juice output.
4. Unscrew the screw in reverse side when the grapes have finished pressing.

The manufactured structure can be used not only for processing grapes, but also for obtaining juice from apples and other fruits.

Important! To get the maximum amount of juice, the prepared raw materials need to be crushed into crumbs or ground in a meat grinder. We wrap the prepared pulp in napkins made of durable material, the portions should not exceed 2 kg, the number of layers should be about three. They must be separated by drainage pads made of perforated stainless steel discs, which are welded in pairs and have a thickness of 2 mm. Between them there are thrust rings having a thickness of 4 mm.

Wooden apple press

The previous model is a reliable option, but it has some disadvantages. Thus, thin stainless material undergoes a very difficult welding process. In addition, special equipment and electrodes are required. Simplify this option designs can be made by making your own basket from boards, and parquet boards may also be suitable.

In order to make a working mechanism with a capacity of 20 liters, you need to prepare 20 boards with dimensions 320x50x15 mm.

How to make a fruit press with your own hands from wood:

• Using self-tapping screws, the boards are attached to two stainless steel strips of 0.5-1 mm. The distance between the boards should be 10-12 mm.
• Then the strips are bent and their ends are connected with stainless bolts. The resulting basket measures 29 cm in diameter and 32 cm in height.
• A wooden circle with a diameter of 27 cm serves as a punch.

Important! If you place planks under the screw, then it is not at all necessary to use a thrust flange.

• At the bottom of the basket, along the entire contour, a drain gutter is laid out for the juice to exit.

Important! As a tray, you can use an ordinary plastic bowl, in which a hole is drilled into which a tube is inserted.

• Apples are cut into small pieces, wrapped in gauze and placed in a basket. During the working cycle, about 3.5-4 liters of juice are produced.

Important! In order to increase the pressure of the press when the press is lowered, boards are laid between the layers.

1. To make homemade juicer, instead of a screw, you can use a car jack, then you don’t need to look for a nut. But in this case it will be necessary to provide robust construction the base against which the device intended for lifting the car rests.
2. The wooden frame press can operate without the use of a basket. Drainage grates and screw with nut are metal elements in this press, which are placed between packages with raw materials. In this case, the manufactured tray must have high sides to prevent juice from grapes and other berries from splashing on all sides.
3. To reuse the bag wipes, rinse them thoroughly in water. If there was a long break between processing processes, the napkins need to be boiled.
4. Berries and pulp should only be wrapped in a damp cloth to prevent the appearance of an unpleasant odor.
5. The resulting pulp from pears and apples is thrown away; they do not have any special value. You can make fruit drinks and jelly from berry pomace.
6. After preparing the grape juice, the wooden basket must be thoroughly washed with an ordinary dishwashing brush, and then scalded with boiling water.

Video material

Now you have several options and schemes to make a press for apples, grapes and other berries and fruits with your own hands. Choose the system for which you have everything you need necessary materials, skills, then no difficulties will arise, and you will be able to process your harvest with ease.

When performing various works in a home workshop, it is often necessary to apply pressure to the workpieces. We will talk about how to make a hydraulic press with your own hands to perform such operations in this article.

Design and functions of a hydraulic press

A hydraulic press is equipment that is specifically designed for processing parts and workpieces by applying high pressure to them. Such a press works due to the pressure of the liquid acting on the elements of its design.

The design of most hydraulic presses provides for a vertical arrangement of the working cylinder, but there are also models in which it is located horizontally. Various models presses can create working forces in the range from several tens to several thousand tons.

Operating principle hydraulic press based on Pascal's law, known to us from school course physics. The press design consists of two working chambers different sizes or, as they are also called, cylinders. The operating principle of a hydraulic press, to describe it in a few words, is as follows.

In the smaller of its cylinders is created high pressure working fluid, which is fed through a connecting channel into a chamber of a larger diameter and acts on a piston connected to the working tool. The latter exerts pressure on the workpiece, which is located on a rigid support to prevent it from moving under its action. All hydraulic presses use special oils as the working fluid.

Hydraulic presses are most widely used when performing operations on metal parts such as stamping, forging, straightening, bending, extruding pipes and other profiles. In addition, using such presses, briquetting, packaging and pressing are performed. various materials(as a rule, a mini-press is used for these purposes).

The design of the hydraulic press allows it to be actively used both in enterprises producing rubber, plastic and wood products, and in other areas. The variety of functions and applications of this equipment determine the existence of its various modifications. For example, on sale you can find a hydraulic table press, a mini press, a hydraulic floor press, a manual hydraulic press, presses with and without a pressure gauge.

Home use options

The use of a hydraulic press in a garage or home workshop is quite common. Use a press that is different small in size, it is possible both when repairing a car and for performing work of another nature.

In particular, with the help of such compact equipment it is possible to press out bearings or silent blocks, as well as press new parts in their place. In addition to automotive repair, a hydraulic press can be used for bending metal parts, creating the required pressure when gluing surfaces, briquetting waste, for squeezing out oil and liquid. Factory equipment for this purpose (even a manual hydraulic press) costs a lot of money, and not everyone can purchase it. Meanwhile, you can make such a press with your own hands, spending only money on purchasing the necessary materials.

What is noteworthy is that the design of a hydraulic press manufactured at home can immediately be adapted to solve a specific problem with a specific part or workpiece. A self-made press will not take up much space; to place it, it will be enough to allocate some space in a workshop or garage. detailed instructions How to make a hydraulic press is given below. There is also a video on this topic at the end of the article.

Home press design

Do-it-yourself hydraulic presses should not have too outstanding technical characteristics, it is enough for them to develop a force of 10–20 tons. This parameter of a homemade hydraulic press depends on what actions you are going to perform with its help.

One of the most common and simple options homemade press

There are a number of other parameters that correspond to not only industrial, but also home-made household hydraulic presses:

• dimensions;
• weight of equipment;
• piston stroke;
• the presence of a pressure gauge in the design of the press;
• characteristics of the bed used.

In homemade presses, the pressure in the working cylinder is usually created using a manual hydraulic pump, which can be either built into the design of such a device or located separately from it. Such design feature depends only on what equipment you choose to make such a device. It is very easy to make a hydraulic press with your own hands if you take a bottle-type jack as the basis for its design. This jack, which is convenient, already has a built-in hand pump in its design.

A bottle-type hydraulic jack is great for use in a DIY hydraulic press.

Before you decide to purchase the right jack for your home hydraulic project, it is important to decide what tasks you will be using it to solve. It depends on how design diagram manual hydraulic press, and the force that it will develop. The next step is to develop a drawing of the hydraulic press that you are going to make yourself. You can, of course, find such a drawing on the Internet and even watch photos and videos of the process of making a press from a hydraulic jack with your own hands. But in this case, you will be faced with the need to adjust your existing devices to someone else’s homemade press.

Developing a drawing of your future homemade press begins with deciding how it will work. There are only two options here.

• The jack will be located at the bottom of the press - on its bed - and will press upward.
• The jack is fixed in the upper part of the press structure and, accordingly, presses down.

However, when choosing a scheme for the operation of a home-made press, one should take into account the fact that for the main part of the jacks produced by modern industry, the only correct location is with the pressing rod up, and placing them differently is simply not allowed. That is why most often the first scheme of a hydraulic press is taken as a basis. The second option is used only in cases where you need to make your own hydraulic equipment for pressing out bearings or bushings from individual components and mechanisms.

Press option with lower jack position

What to consider when developing a drawing of a homemade press

The supporting element of any press, including a homemade one, is the frame, the development of a drawing of which should be approached with the utmost responsibility. Structurally, the bed is a frame, inside of which there is a jack with a working tool that exerts pressure on the part or workpiece.

The type of bed may vary significantly depending on the purpose of the press

The frame of a self-made hydraulic press must have high strength, since it will experience loads in two directions at once. A jack that creates a certain force will simultaneously press on the upper and lower parts of the frame, trying to tear it apart. That is why, when calculating the frame and choosing materials for its manufacture, its strength is ensured with a margin.

The lower part of the frame - its base - is designed taking into account the fact that it must ensure high stability of the entire structure. When calculating the width of the internal opening of the frame of a homemade press, they take into account both the dimensions of the parts and workpieces that will be processed on it, as well as the total dimensions of all constituent elements future press.

Another option for a frame with simplest design reasons for sustainability

When calculating the height of the internal opening of the frame, the following parameters are summed up: the height of the jack, the desired amount of free play of its rod, the thickness of the working element and the part that needs to be processed. If a homemade press is made according to the first scheme, then its design is as follows: the jack is installed on the lower base, and the part is installed in the upper part of the frame; the force from the jack to the part is transmitted through its rod and a movable working platform moving along guides in the side elements of the frame.

In order to ensure that the rod returns to its original state, two springs are used, the lower part of which is attached to the base, and the upper part is attached to the movable working platform. If you decide to make a press from a jack with your own hands, then it is very important to correctly calculate the stiffness of the springs so that they effectively perform all the functions assigned to them.

When implementing the second scheme, a part is placed on the lower base, and the jack is installed on a movable platform, to which springs are also attached, connecting it to the upper crossbar of the frame. In both the first and second cases, a so-called socket is made at the point of contact of the rod with the movable platform or the upper crossbar of the frame, for which a piece of pipe of the appropriate diameter can be used.

Inability to adjust height working area simplifies the design, but significantly limits the options for using the press

A self-made hydraulic press will be much more convenient to use if it includes the ability to adjust the free jack rod, which also affects the permissible height of the workpiece. To do this, you can do the following.

• At the top internal contour the frames have an additional plate, which can move along the guides due to a screw drive with a steering wheel. Thus, it is possible to change the clearance within a fairly wide range for the placement of parts inside the frame.
• You can make a removable stop, which is most often used as a mobile removable platform. The position of such a stop inside the frame can be fixed using bolted connections, for which holes are drilled in the frame at a certain pitch. In this case, the height spacing of such holes should not exceed the free play of the jack rod.
• From a solid piece of metal or metal profile You can make several replaceable inserts-gaskets of different thicknesses.
• You can also use several of the methods described above at the same time.

If you are making a drawing according to which you will make a press with your own hands, be sure to indicate not only the dimensions of the main elements of such a device and the workpiece, but also the other rolled metal from which the frame will be made.

Tools and materials

If you are going to make a hydraulic press with your own hands, then you will need the following tools: Consumables and equipment:

• welding equipment;
• electrodes;
• metal hacksaw or grinder (angle grinder).

In addition, you will need the following elements that will make up your future garage press: a hydraulic jack, two springs that will pull the movable platform to its original state. If you find an old bridge fungus in your garage left over from a renovation, it can be used as an element of a pulling device for homemade presses with a lower jack. In this case, the fungus is put on the jack rod, the upper part of the springs is attached directly to it, and the lower part is fixed to the frame.

The type and quantity of materials required to build a press greatly depends on the chosen design option.

In order to make a press from a jack, you will need the following rolled metal:

• channels (no less than 8 numbers), (with dimensions no less than 40x40), corners with a shelf width of no less than 50 mm;
• a steel sheet with a thickness of at least 8 mm, which will be used as a reliable foundation for the entire structure;
• a piece of steel strip 10 mm thick - for the manufacture of guides and stiffeners, if necessary;
• a piece of pipe - for making sockets for the head of the jack rod.

Manufacturing process

When the drawing of your future hydraulic press is ready, and all the necessary materials, tools, equipment and components are available, we proceed directly to manufacturing. The first thing to do is to cut all the metal, guided by the dimensions indicated in the drawing.

Now you need to make the base of the press, for which prepared square pipes are welded together, and a steel plate is welded onto the rectangle formed from them. Then the side and top parts of the frame are welded together, carefully ensuring that the resulting U-shaped structure is smooth and has strictly right angles in the joints. Now the resulting structure should be welded to the base and we can assume that the frame for your hydraulic press is ready.

The next element that you will need to make for the press is a movable platform. To make it, you can use a channel, square or rectangular pipe. A piece of pipe is welded in the central part of the platform, which will serve as a socket for the head of the jack rod. To make guides for the working platform, you will need two steel strips, the length of which must correspond to the width of the press frame along its outer contour.

Owners of orchards, vineyards and berry plantations are well aware of the problem of crop processing. An effective way to solve this problem is cold pressing of juice. This process allows you to preserve the vitamin value of fruits and berries for a long time without building a bulk storage facility.

The main mechanism of the country “canning shop” is a press for squeezing juice. It helps to quickly and without loss process hundreds of kilograms of ripe crops.

ABOUT existing varieties We will discuss the principles of operation and cost of equipment for obtaining juice in this article. For home craftsmen, information about the features of making a powerful “juicer” on your own will be useful.

Installations designed for squeezing juice are divided into mechanical, hydraulic, electro-hydraulic and pneumatic.

The most common mechanism is a mechanical screw press.

Screw juice press is simple and reliable

The principle of its operation is clear at first glance: crushed fruits are placed in a container with holes, grapes or berries are poured. After this, by rotating the handle, the screw is activated, lowering the flat piston. The squeezed juice flows through holes in the casing into a tray, and from there it goes into jars or other containers.

In addition to stainless steel, solid beech wood is used to make the casing. A drainage grid is made from it. It consists of two halves connected by metal hoops.

A modernized version of such a device is a manual hydraulic press for apples and grapes.

It does not have a perforated container to separate the juice. Instead, several wooden drainage frames are used. Bags with crushed raw materials are placed between them. A manual hydraulic jack develops a large force (from 1 to 5 tons). Thanks to this, the volume of juice obtained reaches 70% of the volume of fruit.

The original squeezing method is implemented in the Grifo hydraulic press. It does not have a hydraulic jack, but a powerful “barrel” membrane is installed. It expands under the pressure of tap water (1.5-2 atm.) and squeezes the juice through the perforated wall of the casing.

A pneumatic press works on a similar principle. Only the pressure membrane in it is filled not with water, but with compressed air from the compressor.

Since all juice presses are paired with choppers, a few words need to be said about these devices. The simplest mechanism is a steel drum-grater placed in a casing with a loading neck. By rotating the handle, the chopper is activated, turning the fruit into fine crumbs and pulp.

A more advanced option is an electrically driven device. Minimum physical effort and maximum productivity are the main arguments in its favor.

It should be noted that the productivity of mechanical presses is low (10-30 liters per hour). However, for most country farms it is quite enough.

To improve the quality and increase the yield of juice, two methods are used:

• Container bags for crushed fruits.
• Wooden drainage grates or stainless steel “pancakes”.

Both methods improve the removal of juice from the middle of the compressed volume. Without such drainage, the middle layers of crushed fruit are squeezed out worse than the top and bottom layers. An additional advantage of using bags is the release of pulp from the juice.

Large volumes of processing require the use of an electric drive. Here two types of equipment can be distinguished: a traditional screw mechanism driven by a pair of “electric motor-hydraulic jack” and a screw press operating on the principle of a meat grinder.

A screw press juicer with an electric motor is designed for processing berries, grapes and tomatoes. By crushing the raw material, the auger forces it through a sieve and produces juice with a large amount of pulp.

Approximate prices

The cost of manual screw presses for squeezing juice directly depends on their capacity. The price for devices with a working volume of 10-15 liters ranges from 9,000 to 15,000 rubles. Behind hand press, which holds 25 liters of raw materials, you will have to pay at least 20,000 rubles.

The average price of home “juice squeezers” driven by a hydraulic jack is 19,000 rubles. A pneumatic press for squeezing juice from apples can be purchased for 34,000 rubles. For a membrane-type hydraulic device, sellers ask 94,000 rubles.

How to make a juice press with your own hands?

The most difficult part of a manual juice press is the powerful screw. It is impossible to do it without the help of a qualified turner. Moreover, every car owner has a mechanism that is perfect for squeezing juice. This is a hydraulic or mechanical jack. Using it, you can make a good homemade juice press.

The main task is to weld a strong frame from a metal profile into which the jack will rest. For this purpose, you can take trimmings square pipe(section 40x40 mm, wall thickness not less than 3 mm).

When making a drawing of the press, the height of the frame is selected based on the height of the jack, the thickness of the linings, drainage grates and bags of raw materials. The width of the frame is made such that the juice tray can easily fit into it.

In order to make the juice press with your own hands as stable as possible, three pieces of square pipe (15-20 cm long) need to be welded to the lower belt of the frame on both sides. A stand made of boards or OSB boards will rest on these “legs”.

The drainage grate should only be made from natural wood(oak, beech). The thickness of the drainage grid boards must be at least 20 mm.

To sew bags, you can use different fabrics (jute burlap, linen, cotton calico, synthetics). The main thing is that it is strong enough so that it will not be torn apart by the pressure of the jack.

In conclusion, let’s look at photographs of a working example of such a press. Without resorting to welding, the master decided to make a frame on bolted connections using a powerful angle and profile pipe.

A piece of laminated chipboard countertop was used for the bottom base plate.

But the master chose the wrong material for the drainage grid. Instead of natural wood, he used OSB board, making cuts in it for the outflow of juice. We do not advise you to repeat this mistake, since particle boards contain toxic phenol-formaldehyde adhesive.

Drainage grate for the press - only wood, not chipboard!

In general, the homemade juice press turned out to be simple, reliable and efficient.

But more complex design DIY hydraulic press. Here the master decided to use a screw as a fastener for a fruit bookmark placed in a perforated stainless steel casing. He placed a hydraulic jack under the frame. The supporting platform is made not stationary, but sliding. The jack moves it up the frame profile.

In this press, the screw does not squeeze out the juice, but only fixes the bookmark

If the trees in your country house bend during the season under the weight of fruits that require urgent processing, you should take care of having a juicer. This problem also arises among winemakers, among whom there are no people willing to process the berries manually. It is quite possible to make a juice press yourself, eliminating additional expenses for purchasing equipment, which is quite expensive today.

Operating principle

Screw type can be made according to different technologies, in this process, parts are used such as old containers, tanks from washing machines, as well as pots and boards. In some cases, structures are made using a jack. If we're talking about O traditional device to obtain juice, the device provides for the following components: a thrust mechanism, a basket, a pressing element, and a base. The basket should be placed on the base, with a tray underneath for receiving juice. The last of these elements provides a gutter, under which a sap receiver is installed.

Making a press yourself

Initially, you will need to prepare the base and frame, which are made of a metal profile. To make a juice press, you will need to form the upper part of the frame, which should be positioned horizontally. For this element, the most durable and rigid profile with thick walls is selected. This will prevent the components from bending under load. A sheet of plywood is laid on the base, on which the tank and tray are installed. In order to prevent frame corrosion, it is necessary to cover the surface with a layer of paint. As for plywood, it is treated with varnish.

Pallet preparation

If you decide to make a juice press yourself, then you will need to prepare a tray; it can be an element of the same name from a large diameter pot. All you need to do is cut a hole in the side and glue a plastic tube into it, with the help of which the juice will flow into the receiver. When working with a pallet, you need to act very carefully, since the product can easily break if it is accidentally caught or something is dropped on its surface. This also applies to operation, since the tube can be torn out due to negligence. In order not to worry about this, it is best to use a tray made of stainless steel.

Making a tank

A juice press must have a tank, which can be made by a craftsman from galvanized steel. When choosing a material, you should stock up on planed pine beams, it should not be glued, you can easily find such lumber in any hardware store. The tank will be made of timber, the cross-section of which should be 20x40 millimeters. The gap between the elements of this product should not be more than 5 millimeters. Due to the fact that wood contains essential oils, as well as resins and glycosides, it is best to use indifferent material as a material for the tank biological material according to the type of natural wood, it can be birch, beech, or oak. As for pine, it is usually not used when making a manual juice press. This is due to the fact that the material contains resins, the content of which can somewhat affect the taste of the juice.

Making a piston

When making a juice press with your own hands, you will need to make a square from two layers of boards, which should be perpendicular to each other. In this case, self-tapping screws should be used as fasteners. The resulting square will allow you to get a piston, and you will need to use electric jigsaw. It is important to make an element that fits in diameter. The pistons should be rounded with a file, which will make it easier to install the elements in the tank. The piston is also made from biologically pure wood such as beech, birch or oak.

Work on the power element of the device

If you are making it for juice, then as power element you can use a screw. A jack will also do. In order to obtain juice, it will be sufficient and which is capable of creating a force equivalent to two tons. Among other things, you should cut the planks that are placed under the jack; this requirement is explained by the fact that the piston stroke will not be enough for the height of the tank; the jack handle will rest against the edge of the barrel.

When making a screw manual juice press, you can use a traditional galvanized pin for the screw. A handle and a nut are welded to it, the latter of which will turn the screw. To filter the juice, you should use enough durable fabric, which has a fine mesh. Polyester or lavsan are perfect.

Making a metal press

When making a juice press with your own hands, you can take as a basis steel structure. To do this, the master will need to have skills in turning or plumbing, as well as have and be able to operate a welding machine. It is based on a stainless steel tank borrowed from an old washing machine. Two cylindrical containers without a bottom are made from it. The diameter of these products should be 23 and 29 centimeters, and the height will be the same, equivalent to 24 centimeters. In a smaller diameter cylinder you need to make holes, arranging them in a checkerboard pattern. Their diameter should be 8 millimeters. The inner container, which will become the basket, is necessary for loading fruits, while the outer one is for juice.

When making a juice press, it is important to place a rectangular tray under the cylinders, which is made of stainless steel and has dimensions of 30x50 centimeters. The sides of the tray must have a triangular bevel, which is necessary for draining the juice. A 21 mm flange will act as a poisson. Its fixation must be rigid; it must be installed on the lower part of the rod.

If you decide to make a press for squeezing juice yourself, then you need to weld a head with a hole that is necessary for the lever to the top of the poisson. Using the last element, the thrust mechanism will be activated. A nut will work in tandem with the screw, which is installed on the U-shaped frame. The latter is fixed to the base; if necessary, it can be concreted into the floor or fixed to the table with screws.

Key secrets

If you use it to make a juice press, you won’t have to grind out the nut, but you need to ensure that the base is strong enough. It is against this that the mechanism that is designed to lift the car will rest. Using wooden press frame type, it will be possible to operate the device without a basket. The steel element in it will be a screw with a nut and gratings that are placed between bags of raw materials.
