our freezer is using the liquid nitrogen as the freezing medium, the lowest temperature can reach at -190℃,
but you can adjust the temperature as your need. our customers often set the temperature at -70℃~-110℃, so the cold 
gas nitrogen loop inside of this cabinet freezer, 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.


 
Compare with the traditional air-cooled quick-freezing equipment, liquid nitrogen instant vaporization contact freezing 
rate can be improved 5 ~ 10 times, can quickly through the food ice crystals point (0 ~-5 ℃), Food within the rapid
