It was known that low temperature drying could produce high quality dried products, because it could reduce the chemical reaction during drying period. Models were developed to predict the moisture content of rough rice in deep-bed and tray-bed dryer. The model was based on heat and mass transfer equations between moist air and rough rice, and it was including a shrinkage effect caused by drying. Regarding tray-bed dryer, the mixing law of moist air was used to simulate low temperature drying. A set of differential equations was solved by finite differential method. Inlet air conditions data were used as input. Predicted results were in good agreement with the experimental data.
