摘　　要：采用机械通风技术，在外温高于粮温时，用7．5kW电机驱动风机强制通风28h，可使原始水分16％的稻谷降低2～2．4个水分。与晾晒、烘干相比，可节约费用5～10倍。最佳通风时间为午夜0时至次日凌晨5时之间。Mechanical ventilation was adopted. 28h ventilation was conducted with 7. 5 kW electrical machinery when ambient temperature was above grain temperature. The paddy at 16% moisture content was lowered 2~2. 4 %. The cost could be saved 5~10 times compared with dry in air and mechanical drying. The optimum time of ventilation was between zero hour at midnigh and five hour tomorrow morning.
