💡 Product Description
Liquid nitrogen temperatures can reach minus -190ºC. When it is in contact with food, gasification will be able to take heat away more quickly. The ultra-low temperature and high heat exchange rate achieve a really quick frozen. Such rapid freezing generates the smallest ice crystals and helps maintain food texture. This also prevents water loss, ensuring almost no loss of original color, flavor, and quality of the food. The vaporized refrigerant nitrogen is directed to the front end of the refrigerating machine uniformly to complete the exchange of hot inverse, improving nitrogen utilization. This equipment is ideal for high-value food such as cooked wheaten products, fish, shrimp, roe, and abalone.
