A theoretical model, based on the well‐known man and energy transport equations for a continuous media, was rigorously developed to describe the liquid diffusion controlled drying of cereal grain in a batch operated, well‐mixed spouted‐bed dryer. The equilibrium moisture content equation and the effective diffusion coefficient are required to solve the heat and mass transfer equations. Numerical techniques were used to solve these equations.The model was tested using laboratory‐scale experiments where rough rice was dried in a spouted‐bed. A good agreement was obtained between the experimental and theoretical model.
