Liquid nitrogen freezing is a mature food freezing technology. Liquid nitrogen quick freezer uses the ultra-low cooling capacity of liquid nitrogen at -196℃ to quickly make frozen food pass through the ice crystal formation zone (-0℃--5℃) within 5-20 minutes, preventing large ice crystals from forming in food cells and destroying cell walls. At the same time, it greatly reduces the water loss caused by the strong wind required for traditional mechanical freezing. It has a fast freezing speed and less water loss in frozen products, which completely preserves the original flavor, freshness and quality of the food, realizing the real low-temperature quick freezing of food.

Liquid nitrogen quick freezer

Cabinet liquid nitrogen quick freezer uses liquid nitrogen spray technology to freeze food rapidly. The rapid cooling by liquid nitrogen generates small and uniform ice crystals and the cell walls of food will not be destroyed. The texture and moisture of the food can be completely preserved to guarantee food quality. The liquid nitrogen fast freezer is suitable for freezing bayberry, durian, mushroom, seafood, meat products, cakes, large-volume products, etc.

Liquid nitrogen injector

The liquid nitrogen injection machine is an ultra-efficient nitrogen injection system designed for low-speed or high-speed production lines. It uses advanced vacuum insulation technology to inject liquid nitrogen into each container. The injected liquid nitrogen then vaporizes to create internal pressure in container, achieving pressurization and deoxygenation purpose. The liquid nitrogen dosing machine is suitable for pressurization and deoxygenation of bottled liquids or solids, such as edible oil, beverages, juice, milk, mineral water, potato chips, milk powder, dried fruits, nuts and cereals, etc.
