A mathematical model for the drying of grain in a continuous vibrated fluidised bed dryer was developed. A plug-flow equipment model in which, a thin layer of particles moving forward and well mixed in the direction of the gas flow was applied. Mass and heat transfer within a single wet particle was described by effective transport coefficients. Assuming constant effective mass transport coefficient and thermal conductivity, analytical solutions of the mass and energy balances were obtained. The variation of both transport coefficients along the dryer was taken into account by a stepwise application of the analytical solution in space intervals with averaged coefficients from previous locations in the dryer. Calculation results were in fairly good agreement with experimental data from the literature. The effects of operational parameters on moisture content and temperature profiles along the dryer were studied.
