cryogenic liquid nitrogen storage tank
For most products, long-term storage in the refrigerator leads to product quality degradation, but for example, fruits such as bananas and oranges can be stored at 0℃ for several days, -30℃ for 1 week, and -50℃ for 2 months.
For most products, long-term storage in the refrigerator leads to product quality degradation, but for example, fruits such as bananas and oranges can be stored at 0℃ for several days, -30℃ for 1 week, and -50℃ for 2 months. C Frozen food quality deterioration is mainly due to the destruction of protein, vitamins and soluble fiber. Due to the low freezing temperature, other nutrients contained in food, cryogenic liquid nitrogen storage tanks as a refrigeration unit have the following advantages:
Because liquid nitrogen has a low freezing point, it has good heat transfer efficiency. Thus, food can be cooled quickly.
Liquid nitrogen has high thermal stability. In addition, the boiling point is only -345 ° C from -196 ° C, so food can be preserved at low temperatures for a long time.
Liquid nitrogen can be cooled quickly. Compared to the existing refrigeration equipment, the freezing time can be greatly shortened.
