Used for cooling or precooling to refrigerate the inlet or to freeze (refer to two times freezing process) at ambient temperature. The processing cycle is generally 12h-24h, and the temperature is generally 4℃ after pre-cooling.
Application : Suitable for the preservation of fruits, vegetables and other kinds of food.
Preservation room maximize maintain the original quality and freshness of some agricultural products, After a period of preservation and storage of agricultural products. Maintain the original quality and freshness of agricultural products Preserving cold storage is to inhibit microbial and enzyme activity, to extend the lasting period of fruits and vegetables.
Preserved storage technology is the main way to keep fresh fruits and vegetables at low temperature. Agricultural products, fruits and vegetables, the preservation temperature range of 0℃ ~ 15℃. Fresh storage can reduce the incidence of pathogenic bacteria and the decay rate of fruit,It also slows down the respiration and metabolism of fruits, to achieve the purpose of preventing decline and delaying storage. The emergence of modern refrigeration machinery, So that the preservation technology can be frozen after the rapid, and greatly improve the quality of fresh storage fruits and vegetables.
Also known as high-temperature refrigeration room, mainly used for storage eggs, fruits, vegetables and other food.
Also known as low temperature cold room, the main storage of frozen food processed, such as frozen meat, frozen fruits and vegetables, frozen fish and so on.
Used to freeze food, from normal temperature or cooling state to rapidly reduce 15-18 Shan, processing cycle is generally 24h.
Used to store artificial ice , to solve the ice peak season and ice capacity is insufficient contradiction.Cold temperature and relative humidity, should be based on various types of food cold processing or refrigeration process requirements to determine.
