| Abstract: | With the experimental study of freeze drying carrot and potato chip, the effects of process parameters of the heat transfer patterns, the heating temperatures and the pressures on the freeze drying were discussed. A simplified mathematical model was established to predict the freeze drying time, the variations of temperature and the weight of material. The experimental results obtained agree well with those calculated by the mathematical model. |
