A large amount of grain loss frequently occurs in developing countries especially in South-east Asia etc. It is believed that one of the factors influencing grain loss is inappropriate husking condition corresponding to the actual cultivating, harvesting and drying conditions. Therefore, immediately after harvest, rice grain was dried by an ordinary circulating dryer at three levels of temperature, (37 deg C, 42 deg C, 50 deg C). With the purpose of further investigating about the influence of over drying condition on the husking process, rice grain was dried until the moisture content reached 14 and 12,5% w.b.. The relationship between husking conditions and various husking properties were measured for each test sample. Next, the relationship between the drying conditions and husking properties were discussed. We found that a low drying temperature of 37 deg C and paddy finishing moisture content of 14% w.b. were the optimum conditions for rice quality maintenance and high energy efficiency.
