What is the standard temperature of the cold storage?

The standard temperature of cold storage usually varies according to different food types and storage requirements.

Refrigeration:-10℃ ~-20℃ for freezing fish, meat, poultry and eggs. ?

Frozen cold storage: fresh fish, fresh meat, rice flour products, frozen ice cream, blood products, chemical raw materials, etc. Store at the low temperature of -20℃ ~-35℃. ?

Controlled atmosphere cold storage: fruits, vegetables, herbs and seeds are stored at 8℃ ~ 0℃ for a long time.

Heating and cold storage: heating and cold storage below 30℃ can be used to ripen tropical fruits such as bananas, mangoes, jackfruit and durian in winter.

Fresh-keeping cold storage: the storage temperature is generally 0℃ ~ 8℃, which is mainly used for fresh-keeping of fruits and vegetables, dairy products, fresh eggs and fresh meat. So as to keep the food at a low temperature, and the temperature is generally not lower than 0℃. Low temperature storage of food does not mean that the lower the temperature, the better, and not all foods can achieve good storage effect at any low temperature. Generally speaking, the storage of food in the fresh-keeping warehouse will not affect its internal organization. Preservation can keep the original flavor and freshness of food. At the same time, customers should not pursue too low storage temperature. The decrease of temperature will directly increase the initial investment and operation cost of equipment.

Cold storage: the temperature is generally-15℃ ~-18℃. Generally speaking, food is put into the cold storage step by step from time to time. After a period of time, the temperature of the cold storage reached-18℃, and the goods were taken away irregularly. There is no specific requirement for this "period of time". This is a typical freezer. ?

Low temperature refrigeration: the storage temperature is generally -22 ~ -25℃, because some foods, such as ice cream and seafood, need to be stored at -25℃ to avoid deterioration. For example, if the ice cream does not reach -25℃ during storage, its flavor will be lost; The umami taste and taste of seafood are much worse; The characteristic of Zirun refrigeration is to put food into the cold storage irregularly and step by step. After a period of time, the temperature of the cold storage reached -25℃. There are no special requirements during this period, but there are strict requirements for the temperature of this cold storage, which is between -22℃ and -25℃. This is a typical low-temperature storage.
