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 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.Liquid nitrogen quick freezing machine is suitable for food with high value, such as cooked wheaten food fish,shirmp, roe, abalone and so on.
1. No damage of cell structure, no dehydration and dry loss,no moisture loss.
- Maximum speed of decreasing temperature ―― ≥ 50ºC/min;
- Maximum speed of increasing temperature ―― ≥ 8ºC/min (used for defrost or sterilization at high temperature);
- Accuracy of temperature control ―― ±3ºC;
- Uniformity of temperature ―― ±1ºC;
2. Improve productivity, improve texture, color, flavor of frozen product.
3. The nitrogen freezer is Environmental, no pollution, no noise.
4. Easy to operate and easy to repair, don't need special technician.
5. All stainless steel SUS304 structure parts
6. Higher quality of the frozen product compared with slower methods
