| Abstract: | Deepfreezing food by using liquid nitrogen is a new effective method to keep it fresh.We introduced an experiment we had done with a deepfreezing tunnel for deepfreezing whitebait,analysed such problems as liquid nitrogen comsumption,congelation crazing and reduction,and finally gave the better method to solve these problems,which is helpful to popularize using liquid nitrogen to deepfreeze food. |
