Food refrigeration application of dry ice

 

1 easy to use and store

 

The use of dry ice for refrigerated foods can significantly extend the storage time of food. If it can be stored frozen for several months, the long-term freezing must be kept at a low temperature of at least -18 ° C, and the dry ice can reach a low temperature of -78 ° C.

 

2 safe and convenient

 

As a refrigerating preservative, dry ice has the characteristics of low temperature, environmental protection, clean and pollution-free, convenient transportation and low cost. In addition, after the dry ice evaporates, it is volatilized into a dry carbon dioxide gas, which has an oxygen barrier effect, so that the food can remain unchanged for a long time.

 

3 sufficient refrigeration, cost-effective

 

Dry ice is a very common food preservation method as a refrigerant medium, and ordinary refrigeration equipment is kept at around zero. The carbon dioxide dry ice -78 ° C, is the temperature that ordinary refrigeration equipment can not reach.
