Food cold storage is used in food raw material freezing and cold storage buildings, it is a method that using artificial refrigeration to keep the rolls must be low. In order to reduce the heat into the outside world, the cold storage of floor, wall and roof laying a certain thickness of moistureproof gas insulation and heat insulation layer, in the food cold storage engineering management, should according to the characteristics of the food cold storage, implement scientific management, to ensure the safety in production, prolong the service life, reduce production cost, save maintenance costs, enhance economic efficiency of enterprises.

　　The purpose of the food cold storage

　　Food cold storage can be widely used in food factory, supermarket, meat cold storage is mainly used for the food, dairy products, meat, aquatic products, poultry, such as constant temperature storage.

　　Generally much by refrigerator refrigeration and cold storage engineering, the use of gasification temperature is very low fluid as the coolant, the evaporation under the condition of low pressure and mechanical control, absorb the heat inside the storehouse, so as to achieve the purpose of cooling. Is the most commonly used compression type refrigerating machine, mainly consists of compressor, condenser and evaporation tube, etc.

　　According to the way of evaporation duct device and can be divided into direct and indirect cooling cooling two kinds. Direct cooling evaporation duct installed inside a refrigerated warehouse, liquid coolant through the low pressure evaporation tube directly absorb heat and cooling in the warehouse. Indirect cooling by fan will air suction inlet air cooling device in the warehouse, the air is hovering in the cooling device of evaporation tube after absorption of heat, into the house of the rolls and cool again. Air cooling method has the advantage of rapid cooling, the temperature inside is relatively uniform, but will be generated in the process of the storage of carbon dioxide and other harmful gases with outbound.

　　Meat industry is the backbone of the food cold storage industry, is the relationship between major industry of national economy and people's livelihood, and to promote the development of the food cold storage chain, the development of rural economy, the prosperity of urban and rural markets and expand the foreign trade is playing an increasingly important role.

　　Food cold storage points L, Q, J level, vice recruit 9 is 5-5 c libraries, and 10} - 18.01-20-23 c, special can reach below - 3 u0c refrigerator. Can meet the need of different play, is to store the meat's aquatic products, eggs, dairy products, fruits, vegetables, such as the ideal refrigerator, widely applicable to all the various departments. Energy return, cold storage insulation performance is superior, the cooling speed turn centuries between the attached short length compared with other materials production of refrigerator can birth control} 7 tightness by 0% for 30 series matching r6t goods cold storage library board for refuse to become warped love with production of smoked the combination of different sizes, can form a variety of specifications of cold storage, for users to make full use of existing venues built space provides a convenient and cry. At present, the products have two types of indoor and outdoor; A bar, two rooms, suites, more than one type can be designed, lateral change of tree area can be designed with air-cooled refrigeration unit.
