Low temperature food refrigerators for fruits and vegetables are mainly used to refrigerate food fruits and vegetables to extend the quality of food. They are mainly used to refrigerate the interior of the refrigerators, so that the indoor temperature can reach a lower value of food decay and deterioration. That is, the storage of food refrigerators is mainly to inhibit the rate of food metabolism through the low temperature effect, thus extending the shelf life of food.
The refrigerated and refrigerated stereoscopic warehouse has high requirements on the sealing performance of the warehouse body, and it is required that the warehouse should not be warehoused and warehoused repeatedly. Therefore, the fruit and vegetable food refrigerated warehouse is widely used in large fruit and vegetable food trading markets. The basic construction of fruit and vegetable food cold storage is based on the adjustment of the proportion of N2, O2, CO2, ethylene and other components, the relative humidity, temperature and standard air pressure in the storage body, and the inhibition of the respiration of the storage cells to slow down its metabolic process, so that it is in the near dormancy mode, which can ensure that the texture, color, taste, nutritional value, etc. of the stored materials will not deteriorate basically for a long time, so as to achieve the practical effect of long-term preservation.

Structural composition and characteristics of HEGERLS refrigerated warehouse
At present, most of the fruit and vegetable food storage refrigerators are installed in movable combined refrigerators. The installation of combined cold storage is characterized by strong flexibility, simple structure, convenient operation and easy management. The installation of the combined cold storage mainly consists of six parts: the storage body, the storage door, the refrigeration compressor, the air cooler, the automatic control components, and the electric control system. The specific functions and characteristics are as follows:
1) Thermal insulation material of warehouse body: polyurethane or polystyrene is generally used, and plastic coated color steel plate, stainless steel plate, aluminum alloy plate, etc. are applied externally. The warehouse plate should have the characteristics of automatic film pasting, automatic filling, automatic rib rolling and automatic molding to achieve the thermal insulation effect of the fresh cold storage and reduce the operating cost of users.
2) Refrigeration compressor: its function is to rapidly cool down the cold storage. It should have the characteristics of excellent performance, convenient operation, low failure rate, etc.
3) Air cooler: the ceiling type air cooler is basically adopted, which can not only reduce the occupied volume in the warehouse, but also solve the problem of system oil return, so that the unit can work normally and has a long service life. It plays the role of heat preservation, ventilation and turbidity removal.
4) Automatic control components: mainly designed for the sensitivity and usability of the refrigeration regulation of the system.
5) Electric control system: electric temperature control, with electric defrosting final temperature control. After the cold storage is installed, an electric control system can electrically control the temperature of multiple warehouses.
6) Warehouse door: It mainly plays the role of heat preservation and beauty. A small window is installed on the door, so as to avoid the leakage of cold air and better heat preservation when taking things.

4) The plate of the refrigerated and refrigerated warehouse adopts the lacing and bubbling method, which has good air tightness and heat insulation; The storage body is integrated, with good rigidity, which is relatively good for large low-temperature storage at present; At the same time, with its flexibility, short construction period, excellent energy-saving effect, it is more and more popular with users. It is a better choice to replace the civil cold storage.
So, what matters should be paid attention to during the installation of low-temperature food, fruit and vegetable cold storage?
◇ Dry consumption
The storage of fruit and vegetable food should take into account the problem of consumption. The direct refrigeration method should be used as far as possible in the fruit and vegetable food cold storage. Cold air will further improve the dry consumption of fruit and vegetable food.
◇ Technical elements
The storage temperature of fruits and vegetables is usually between 0 ℃ and 15 ℃. Different fruits and vegetables have different excellent storage temperatures, so they should be separated and stored according to the temperature. It should be known that too high storage temperature will promote the aging and deterioration of fruits and vegetables, while too low storage temperature will cause cold damage and freezing damage. At the same time, the relative humidity of the cold storage should also be considered.
◇ Power consumption of cold storage
The assembly design of the cold storage should take into account the economic cost of the later application. The important thing is the power consumption of the cold storage in the later application. To save power consumption, it is necessary to reduce the unit heat flow of the cold storage bent structure. First, the thermal conductivity of the thermal insulation material should be small, and second, the bent structure layer should be thick. However, the thickness should not be too thick, otherwise there will be more construction costs and space consumption. In addition, in order to reduce the radiation of absorbed sunlight, the surface of the cold storage wall is usually sprayed in milky white or light color. At the same time, the cold storage building should avoid the spread of water vapor and the infiltration of air.
◇ Environmental problems
The top plate of the refrigeration equipment of the food cold storage must not be piled with sundries, otherwise the food cold storage plate will be deformed and affect the thermal insulation characteristics. Therefore, it is necessary to maintain the smooth passage around the refrigerated warehouse to ensure excellent heat conduction. The cold storage construction site shall be kept dry, clean, free of flammable objects, and free of any safety risks. A corresponding gap shall be reserved before the evaporator to prevent interference with the refrigeration function.
