Fresh fruit and vegetable fresh-keeping cold storage is the main way to inhibit the activity of microorganisms and enzymes and prolong the low-temperature preservation of fruits and vegetables. Fresh-keeping cold storage technology is the main way to keep fresh fruits and vegetables at low temperature. The preservation temperature of fruits and vegetables ranges from 0 °C to 15 °C. Preservation storage can reduce the incidence of pathogenic bacteria and the rate of decay of fruits, and can also slow down the respiratory metabolism of fruits, thereby preventing the decline and prolonging the storage period. The emergence of modern freezing machinery enables fresh-keeping technology to be carried out after rapid freezing, which greatly improves the quality of fresh-keeping and storage of fruits and vegetables.

　　advanced technology:

　　The ice-making series cold storage adopts frost-free quick-freezing refrigeration mode, equipped with ** compressor and refrigeration accessories, adopts automatic frost, and the control mode has microcomputer intelligent control. The refrigeration system uses green refrigerant and belongs to the 21st century international advanced refrigeration technology.

　　Novel materials:

　　The library body is made of rigid polyurethane or polystyrene foam insulation sandwich panels and is molded by high-pressure foaming process. It can be made into various lengths and specifications to meet the different requirements of users. Its characteristics are: good thermal insulation performance, light weight, high strength, corrosion resistance, anti-aging and beautiful appearance. The types of cold storage panels are: colored plastic steel, salinized steel, stainless steel, embossed aluminum and so on.

　　Easy to assemble and disassemble:

　　All the ice cold storage slabs are produced by the agreed abrasive tools. They are connected by internal concave and convex grooves. The assembly and disassembly and transportation are convenient. The installation period is short. The small and medium-sized cold storage can be delivered in 2~5 days. The storage body can be combined, separated or added according to user needs. Big and small.

　　Widely used:

　　The cold storage temperature is +15 °C ~ +8 °C, +8 °C ~ +2 °C and +5 °C ~ -5 °C. It can realize a double temperature or multiple temperature to meet the needs of different users.

　　Large, medium and small cold storage

　　1. Cooling room

　　It is used for cooling or pre-cooling of room temperature foods that are refrigerated in the warehouse or need to be pre-cooled and then frozen (refer to the secondary freezing process). The processing cycle is generally 12~24h, and the temperature after product pre-cooling is generally 4°C.

　　2. Freezing room

　　For video that needs to be frozen, it can be quickly reduced to -15 ° C or 18 ° C from normal temperature or cooling state, and the processing cycle is generally 24 h.

　　3. Cooling room

　　Also known as high-temperature refrigerated rooms, mainly used for storing fresh eggs, fruits, vegetables and other foods.

　　4. Frozen storage room

　　Also known as low-temperature refrigerated rooms, mainly stored frozen processed foods, such as frozen meat, frozen fruits, frozen fish and so on.

　　5. Ice storage

　　Also known as the ice storage room, used to store artificial ice, to solve the contradiction between the need for ice season and insufficient ice production capacity.

　　The temperature and relative humidity of the cold room should be determined according to the requirements of various types of food cold processing or refrigeration process. Generally, it can be selected according to Table 1-1-1.

　　Optimal storage of food frozen storage

　　Cold room name Room temperature (°C) Relative humidity (%) applies to food range cooling rooms. Meat, eggs and other cooling rooms -18 ° C ~ -23-28 ~ -30. Meat, poultry, rabbits, ice eggs, vegetables, ice cream and other fish, shrimp and other cooling products in the cold room 085 ~ 90 cooled meat, poultry.

　　Cold room name room temperature (°C) relative humidity (%) for food range, fresh-keeping cold storage -2~080~85 fresh eggs, fresh-keeping cold storage -1~190~95 chilled egg, Chinese cabbage, garlic, onion, carrot, cabbage Wait. Fresh cold storage 0~285~90 apples, pears, etc. Fresh-keeping cold storage 2~485~90 potatoes, oranges, lychees, etc., fresh-keeping cold storage 1~885~95 bell peppers, beans, cucumbers, tomatoes, pineapples, mandarins, etc., fresh-keeping cold storage 11~1285~90 bananas and other frozen things -15~ -2085~90 frozen meat, poultry, rabbit, ice egg, frozen fruits and vegetables, ice cream, etc., frozen library -18~-2390~95 frozen fish, shrimp, etc., ice storage -4~-10 ice cubes.
