A user oriented simulation model for deep bed solar drying of rough rice

A computer model based on mass and energy balance has been developed which incorporates a range of solar flat plate air heating collector geometries and a drying model based on the thin layer drying principle. This model will be useful in understanding the extreme complexity of the drying process which is influenced by many design parameters. The developed model will also be helpful as a decision making tool in assessing suitable solar collector design options to meet the desired drying requirements. The collector and drying models have been tested separately for a wide range of operating conditions. A description of the models and their assumptions, together with some simulation results for rough rice drying are presented in this paper.
