Digital simulation of agricultural drier performance

Abstract

A method of digital simulation of the performance of different configurations of driers for agricultural materials is proposed. It is based on the “thin-layer” drying rate for the material, the heat and mass balance in the drier and the rate of heat transfer from the air to the stock. The validity of the simulation has been checked by comparing predicted values with those measured in static, fluidized bed and cross-, contra- and co-flow grain driers and those measured in both static and drum type grass driers.
