摘要：

This paper establishes a unsteady mathematic model of freeze drying process. Analysis of the numerical results of the model indicates that different heating methods lead to different laws of energy's disturbation in increasing the temperature of the products and in sublimating the ice. Also the influence of heating methods on reducing the drying time is studied. The numerical results agree well with the experimeni.
