The advantages and need for on-farm drying of paddy were discussed. A literature review on the use of waste engine heat for drying of paddy was carried out. The fundamentals of low temperature drying of paddy in Malaysia was evaluated theoretically. In the preliminary experimental investigation, a 3hp. gasoline engine (driving axial fan) was used to blow air through a grain bed of area 8 ft.x 8 ft. (i.e. 2.4 m x 2.4 m). The importance of weather conditions on low temperature drying of paddy was illustrated.
