Abstract

|
Low-temperature in-bin drying with high-moisture paddy were demonstrated and studied under local autumn weather condition. Paddy with the initial moisture content ef about 24.5 percent in the steel storage bin(diameter: 3 m, height: 3.17 m) was uniformly dried to about 15 percent by continuous blowing of ambient air (average temperature: 10.5℃, RH: 58 percent) in the middle part of October. The amount of grain and grain height were 4.19 M/T and 90 ㎝ respectively. Total fan operation time was 288 hours and airflow rate was 4.81 ㎥/min/㎥ of paddy. Mean drying rate was 0.03 percent per hour and enery requirement for fan operation was 0. 38 KWh per ㎏ water removed.
