The operation of the refrigerator for vegetables and fruits is based on the principle of instant cooling. When the products are loaded for the first time, they are cooled to desired temperature. Then the products are stored in comfortable conditions. In this case, a specific storage regime is established for each fruit.
- Temperature,
In the refrigerator compartment for storing vegetables and fruits, the temperature can range from minus 5 to plus 18 degrees, depending on the name of the loaded product. The temperature will be different for different fruits. - Air humidity,
Unlike packaged products, an important parameter for vegetables and fruits is the air humidity in the refrigeration chamber. If you do not take it into account, the product will dry out, it will deteriorate, and also lose its presentation. You can also see the air humidity parameters in the table. - Adjustable gas environment,
An important condition To ensure long-term storage of vegetables, berries and fruits in the refrigeration chamber, it is necessary to control the composition of the air. In the refrigerating chamber the concentration of oxygen, nitrogen, carbon dioxide and ethylene. When using RGS, the costs of such a refrigeration room (as well as the complexity of installation and operation) increase significantly. True, the shelf life of vegetables and fruits increases proportionally.
Chamber equipment for vegetables and fruits
Refrigeration unit
If the volume of the refrigerating chamber is from 4 to 50 cubic meters. m. preference should be given to industrial refrigeration units: monoblocks and split systems. Monoblock involves installing a heat removal unit directly from outside chambers (represents a single structure with a cooling unit, is inserted into a slot in the wall of the refrigerating chamber). Unlike him, external unit Split systems can be removed from the refrigeration chamber at a considerable distance (up to 20 meters, and can also be placed outdoors). This allows you not to heat the room in which the chamber is located, while reducing the noise level from the refrigeration unit.
Price refrigeration equipment ranges from 35,000 rubles (for the most modest monoblock of 4 cubic meters) to 145,000 rubles (for a three-phase split, designed for 54 cubic meters)
This is what the monoblock looks like:
And so, a split system:
Humidifier
The most budget option To maintain the required humidity in the refrigeration chamber, install an ultrasonic industrial air humidifier. Its features include connection to a water supply system, as well as high performance steam (3 kg per hour or more). Installed outside the refrigerating chamber, steam is supplied to the chamber through a slot in the wall through special air ducts. In this case, they should be placed at a distance from the evaporator of the refrigeration unit, taking into account possible freezing. If one steam generator is not enough to provide the required moisture concentration, several can be installed.
An example of such a humidifier is in the photo, the cost is 58,000 rubles with a productivity of 3000 g. at one o'clock:
Equipment for Controlled Gas Environment
Nitrogen generator,
It is used to increase the concentration of nitrogen in the chamber, costs from 150,000 rubles.
Scrubber and CO2 generator
Reduces the concentration of oxygen in the refrigerator immediately after loading it or after opening the door (increasing the concentration of carbon dioxide). Also used to remove impurities from CO2. The price greatly depends on the power of the equipment; we could not find an installation cheaper than 300,000 rubles.
Ethylene converter,
Some fruits release ethylene during storage. An increased content of this gas in the refrigerating chamber leads to rapid overripening of fruits, significantly reducing the shelf life. During operation, the ethylene converter removes excess gas in the chamber. The cost starts from 500,000 rubles.
Automation,
To control all parameters of the refrigerator for vegetables and fruits, serious electronics are required. Lack of demand in industrial scale, as well as the complexity and individuality of systems lead to significant costs. It is difficult to give specific numbers; we can only list the main functionality: control of temperature and humidity, control of gas concentrations in the air, turning on and off of all system components depending on operating parameters, emergency and light alarm for cold storage operators.
To summarize, we note that the simplest refrigerator for storing vegetables and fruits should include control of temperature and air humidity. A controlled gas environment is the choice of large wholesalers, allowing for shelf life until the next harvest, but also increasing the cost of storage by an order of magnitude.
Equipment for storing vegetables and fruits
Isn’t it good to grow vegetables and fruits on your plot? Nowadays, when the market and store shelves are filled with fruits full of unhealthy chemicals, feast on own products pure pleasure. But if you are lucky and the harvest was a success, how to store a large amount of provisions? There is only one way out - buy a refrigerator for vegetables and.
How does refrigeration equipment work for storing fruits and vegetables?
The refrigerator is not an ordinary one household refrigerator which can be seen in every home. Main principle operation of the device - the formation of optimal storage conditions for a certain type of product. As is known, vegetables and fruits have low resistance to the development of pathogenic bacteria and other microorganisms. In addition, they are characterized by a slight loss of water, as a result of which the presentation of the fruit deteriorates, and the overall weight decreases. All these unfavorable factors can be easily solved by using a refrigerator.
Refrigeration chambers for storing vegetables and fruits they work on the principle of instant cooling. After “shock” cooling, a temperature regime that is quite comfortable for the stored products sets in in the unit’s chamber. Moreover, the temperature is set automatically, depending on the type of fruit. In general, the range is 0+14 ⁰С. It is at this temperature that all chemical and biological reactions in fruits slow down. Moreover, citrus fruits and carrots have completely different temperature regimes. For example, for grapes they set 0+2 ⁰С, for 0 ⁰С, apples - 0+4 ⁰С, bananas - +7+12. In addition, the refrigerator must have a certain humidity level to prevent your fruits and vegetables from spoiling. Long-term storage of food is impossible without ventilation.
Thus, the refrigerator compartment for vegetables and fruits is a sealed device with automatic system regulation and control of temperature, ventilation and humidity. Therefore, simply bring the collected fruits to the unit, lay them out in compartments and display them required parameters according to the type of product.
Refrigerated cabinets are used not only in everyday life, but also for sale in stores and supermarkets for display or storage.
How to choose a household refrigerator for vegetables and fruits?
For home use It is optimal to purchase a cabinet-type unit with one or two doors. Doors can be metal or glass. The first thing you should pay attention to when purchasing is the dimensions of the refrigerator compartment. It is worth considering where the device will be placed and take into account the features of the room. Also be mindful of how you get the camera through the doorway.
Please note that there are parameter adjustments. Most best option– a refrigerator with several zones with the ability to control the temperature in each of them. The absence of zones will allow you to set only one temperature mode in the entire chamber.
Consider the volume of refrigeration equipment. You should calculate the approximate volume of food you intend to store. The minimum volume found on sale is 35 liters.
If we talk about the materials from which the refrigeration cabinet is made, then the most durable, especially in conditions of high moisture, is a product made from of stainless steel. A cabinet made of metal coated with paint, unfortunately, quickly loses its beautiful appearance.
The TOROS group of companies is engaged in the production, sale, installation and maintenance of refrigeration chambers for storing vegetables and fruits both in Moscow and throughout Russia and neighboring countries.
It is known that storing garden and vegetable fruits is a troublesome task. But year-round demand for fresh vegetables and fruit gives birth to a proposal. It is in order for a business to develop properly, regardless of the season, that a refrigerator for vegetables and fruits is needed.
The secret to success is fresh vegetables
The essence of this equipment is to create the most comfortable storage conditions, taking into account the characteristics of the goods being sold. A certain level of humidity must be maintained in the refrigerator compartment. If these criteria are violated, the product may deteriorate.
Modern equipment, be it a refrigerator for vegetables or a refrigerator for fruit, has control and regulation systems - you just need to set the required parameters for humidity, ventilation and select the temperature mode.
The storage conditions described above are called gas control technology. Thanks to this technology, the chamber creates optimal conditions for every type of fruit and vegetable.
Complete set of refrigeration chambers
The refrigerator compartment for vegetables and fruits is assembled from the following components:
- cooling system, selected taking into account the size of the chamber, the volume of loaded products and, accordingly, the type of product;
- refrigeration chamber (the most important thing is its tightness and ergonomic geometric shape);
- humidity control system;
- ventilation;
- general control system;
- general management system;
- nitrogen generator.
A refrigerator equipped in this way is automated system which can preserve vegetables and fruits for a long time. Such cameras are very effective and reliable, but despite this, they require installation, and Toros specialists provide these services.
If you need to maintain small batches of product in proper condition, then it is best to use walk-in cabinets for vegetables, or simply refrigerators.
The refrigerator for vegetables and fruits has a gentle cooling mode. Humidity in refrigerated cabinets is maintained due to the natural evaporation of moisture from food. Our company Toros offers a wide selection of models of this type. Most often, a refrigerator for fruits and vegetables is installed in trading floor and is equipped with transparent doors. Thanks to this, refrigerated cabinets serve as a stand.
We offer many models for various points sales Toros company will be happy to help you choose perfect option for the prosperity of your business.
IN last years With the growth in the construction of suburban housing and cottages, the number of orders for refrigeration chambers for storing fruits and vegetables at a consistently positive temperature has increased. At proper storage In the refrigerator compartment, vegetables and fruits retain freshness and vitamins for a long time.
Proper storage of vegetables and fruits is compliance temperature regime and humidity conditions. It is necessary to maintain the same air temperature throughout the year. Accordingly, in summer it is necessary to cool, and in winter - to heat the volume of the refrigeration chamber or storage for vegetables and fruits. Cooling of the refrigeration chamber and storage is carried out using a refrigeration unit, using air coolers installed in the chamber. Heating is carried out either by heaters operating on various types energy (electric, thermal from water, preheated air, etc.), or using the same air coolers, turning on their heating elements for heating.
