liquid nitrogen tunnels quick freezer

The tunnel freezer uses liquid nitrogen (LIN) as a refrigerant to freeze food directly, suitable for all kinds of foods. It is
modular in design, enabling you to expand production by adding additional tunnels for a longer freezing production line. It is available in several models and belt widths with production rates of 300–2,500 kg/h .
Liquid nitrogen temperatures can reach minus 196℃(-196℃).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 reozen.Such repid freezing,generating the smallest ice crystals, and helps maintain food texture.This also prevents water loss, and almost no loss:to maintain the original color,flavor and original quality of the food.These vaporized refrigerant nitrogen is directed to the front end of the refrigerating machine uniformly,complete the exchange of hot inverse,thereby improving the utilization of the nitrogen
