Research on minimizing postharvest losses and the effective utilization of energy resources for crop drying has led to the idea of using waste heat from an internal combustion engine for crop drying. In a warm humid climate the air must be heated for any type of mechanical drier to accomplish effective drying of grain to about 14.5 to 15% m.c. An engine powered batch drier was built for drying grains, and the performance analysed. The performance of such a system as applied to drying of rough rice is discussed. Information on the calculation of available waste heat for crop drying, fan requirements and specification for the design of the flat bed drier are also presented. Results have shown promise for this type of grain drying unit, especially in the major rice growing regions where the same engine used for pumping irrigation water can be used to drive the fan and provide the waste heat used to dry the grain.
