Liquid nitrogen freezing equipment

Liquid nitrogen freezing just use this and spray liquid nitrogen on the sea food. The temperature difference is over 200 K now and the sea food can be completely frozen in about 20 minutes.It is tens of times faster than normal freezing ways. Since the freeze time is short, the ice crystal is very small. The freezing speed is faster than the intracellular vapor permeation rate while producing ice crystals inside and outside cells, so there is no damage of the cells. This way could maintain the original color, smell, taste and freshness; it is the recognized as the best way of freezing sea food in the world.
