 the quick-freezing time is short and the freshness-keeping time is long.

　　 (1) Avoid the formation of large ice crystals between cells.

　　 (2) Reduce intracellular moisture exudation, less juice loss when thawing

　　 (3) The contact time of concentrated solutes and food tissues, colloids and various components in the cell tissues is significantly shortened, and the harm of concentration is reduced to a very low level

　　 (4) The food is rapidly reduced to below the temperature of microbial growth activity, which advantageously resists the growth of microbes and their biochemical reactions.

　　 (5) Aquatic products liquid quick-freezing fresh-keeping equipment: freezing and quick-freezing fast (just a few minutes to ten minutes), high efficiency, low operating cost

　　 (6) Due to the ultra-low temperature freezing technology, it can completely kill the virus when the product is frozen. After the product is quick-frozen, it can be directly put into the freezer for refrigeration, and there is no need to worry about the damage of the food by the reproduction of the food.

(7) The food stays in the freezing equipment for a short time, which is beneficial to improve the utilization and continuous production of the equipment. Most foods start to freeze when the temperature drops to -1°C, and most of the ice crystals are between -1°C and -5°C. This stage is called the very high ice crystal formation stage. Liquid quick freezing can greatly shorten the freezing time at this stage, and can quickly remove this part of the heat, which is of great significance for improving the quality of quick-frozen food
