| Abstract: | The characteristic of LN_2-spraying fluidized cooling system was investigated in this paper. The freezing process was calculated by using enthalpy method. Freezing processes and time of cucumber slices at different conditions were got by numerical simulation. The results showed coincidence with experimental data. Finally, the quality of freezing food was evaluated in the paper. |
