What's the difference between fruit storage and refrigeration?

Fruit fresh-keeping warehouse and cold storage Conceptually, cold storage includes fruit cold storage. Fruit cold storage is a kind of cold storage according to the types of stored goods.

Definition of fruit refrigeration in refrigeration classification;

Fruit cold storage: used for storing and processing fruits, using low temperature or controlling the content of oxygen, carbon dioxide and other gases in the warehouse. A storage method for inhibiting the activity of microorganisms and enzymes and prolonging the long-term storage time of fruits and vegetables. There are two kinds of fruit refrigeration: fresh-keeping storage and modified atmosphere storage.

The difference between the two:

(1) Different storage items

The goods stored in the fruit cold storage are relatively simple, limited to fruits and vegetables;

There are many goods stored in the cold storage, which can meet the storage needs of different goods (fruits, vegetables, meat, dairy products, medicinal materials, etc.). );

(2) Different temperatures

The general design temperature of fruit cold storage is 0℃- 15℃ (the design temperature of modified atmosphere storage in fruit preservation is 5℃-2℃). ) common fruit refrigeration temperature:

Grape: the suitable cold storage temperature is-1℃ ~ 3℃;

Apple: the suitable cold storage temperature is-1℃ ~+1℃;

Pear: the suitable cold storage temperature is-1℃ ~+℃;

Watermelon: the suitable refrigeration temperature is 2℃ ~ 4℃;

Strawberry: the suitable cold storage temperature is-65438 0℃;

Grape: the suitable cold storage temperature is-1℃ ~ 3℃;

Apple: the suitable cold storage temperature is-1℃ ~+1℃;

Pear: the suitable cold storage temperature is-1℃ ~+℃;

Watermelon: the suitable refrigeration temperature is 2℃ ~ 4℃;

But the temperature range of refrigeration is relatively wide: for example

High temperature cold storage (constant temperature storage): the design temperature of cold storage is 5℃ ~15℃;

Medium temperature cold storage (cold storage): the design temperature of cold storage is 5℃ ~-5℃;

Low temperature cold storage (freezer): the design temperature of cold storage is-18℃ ~-25℃;

Ultra-low temperature cold storage (deep cold storage): the design temperature of cold storage is-45℃ ~-60℃;

Quick-frozen warehouse (quick-frozen warehouse): the design temperature of cold storage is-35℃ ~-40℃;

Fresh storage (controlled atmosphere storage): The design temperature of cold storage is 5 ~-2℃.
