Low temperature liquid nitrogen quick freezing technology principle
Low-temperature liquid nitrogen quick-freezing technology is the application of [ice crystallization theory], using liquid nitrogen ultra-low temperature -196 degrees, to make the frozen items pass through the largest ice crystal formation area in a very short time, so that the pressure inside and outside the food cells is relatively balanced, and the maximum degree It is a new food preservation technology that protects the cell tissue of frozen items, maintains cell activity, ensures the fresh quality of frozen items, and retains the original nutrients to the greatest extent.
