The fuel crisis has emphasized the need to search for ways and means of decreasing the energy consumption in grain drying. A heated granular-solid transfer medium has been studied by various investigators to improve drying efficiency (lengar et al. 1971 Raghavan and Harper 1974 Lapp and Manchur 1974). Heated steel plates, sand and granular salt have been used successfully for quick and efficient drying of corn, oilseeds and paddy rice. Experiments on a model batch dryer by Lapp et al. (1976a,b) were conducted using 12-30 texture sand (0.59- to 1.65-mm particle diameter). Wheat was dried from 17.0 to 14.5% wet basis with sand heated to 100
