Product Description
In cold storage is the different temperature cooling food and frozen food machinery in different temperature refrigeration for short-term or long-term storage. Mainly applied in meat and aquatic products stored. The temperature is low temperature library in - 20 degrees centigrade, because seafood and cold drinks need 20 degrees centigrade in - doesn't go bad, if short of - 20 degrees Celsius seafood freshness is quite different. The characteristics of low temperature library is gradually will instrument into regular refrigerator, after a period of refrigerated 20 degrees Celsius, the temperature reaches - to this period no special requirements, but was strict requirements for library in - 18 degrees Celsius, between 23 degrees centigrade ~ is the typical low temperature library, but the cold storage, library containing dairy products should be set at temperature 20 degrees centigrade ~ - 28 degrees Celsius can, but these two kinds of different temperature require different levels of equipment, equipment investment has the very big disparity. Generally speaking refrigeration is there will be such needs food, in order to keep it quality storage under the required temperature. Because when the temperature drop to 15 degrees centigrade, food freeze rate is higher, microbes and enzymes basically stop activities, growth, oxidation is very slow. So food can be stored for a long time, and has better refrigeration quality. In addition, frozen food also require relatively stable temperature to Chambers, temperature fluctuations will cause excessive food decaying.
