摘　　要：稻谷(糙米)在储存过程中,因其本身呼吸作用及生化变化,水分逐渐降低,低水分值对稻谷的安全保管是有益的,但对稻谷的加工来说却降低了其品质,使大米精度下降,碎米率增加,出米率降低,口感变差。为此,对逆流糙米通风加湿调质进行了试验,研究了逆流糙米通风加湿调质的加湿特性。研究结果表明:随着风温的增加,单位热耗减小,加湿速率增大,出机粮温线性增加;随着风速的增加,单位热耗增大,加湿速率增大。Rice（rice） in the storage process,because of its itself respiration and biochemical changes,moisture to gradually reduce,low moisture value on the safety of rice storage is useful,but to the rice processing,but lower the quality,make rice precision drops,broken rice rate increased,milled rice rate is reduced,palate bastardize.This article through to countercurrent brown rice ventilation humidifying quenched and tempered the test,studied the countercurrent brown rice ventilation humidifying adjustable qualitative humidification characteristic.The results show that,with the increase of air temperature,heat consumption per unit is reduced,wetting rate increases,the grain temperature increases linearly with the increase of wind speed;,unit heat consumption increases,the humidifying rate increases.
