Low-temperature in-bin drying with high-moisture paddy were demonstrated and studied under local autumn weather condition. Paddy with the initial moisture content of about 24.5 percent in the steel storage bin (diameter: 3m, height: 3.17m) was uniformly dried to about 15 percent by continuous blowing of ambient air (average temperature: 10.5 deg Centigrade, RH: 58 percent) in the middle part of October. The amount of grain and grain height were 4.19 M/T and 90 cm, respectively. Total fan operation time was 288 hours and airflow rate was 4.81 m2/min/m3 of paddy. Mean drying rate was 0.03 percent per hour and energy requirement for fan operation was 0.38 KWh per kg water removed
