摘　　要：研究了在相同的干燥周期、不同的供热方式 (高温供热与低温供热 ) ,稻谷在双循环红外辐射与热风联合的振动流化床上的脱水量及爆腰增加率 .实验结果表明 :高温供热 (最高温度 46.5℃ )比低温供热干燥 (最高温度 3 5 .3℃ )时效果好 ,即前者脱水量为后者的 2 .2 (2 .5 3 / 1.15 )倍 ;后者爆腰增加率为前者的 5 (2 .5 / 0 .5 )倍 .因此 ,研究合理的干燥工艺过程 。This paper studies the dewater volume and increasing rice cracking its rate of the rough rice on the vibrofluidized bed of hot air combined with the double cycle infrared radiation in the same drying period and different heating ways(high temperature heating and low temperature heating).The experimental results indicate that drying in high temperature heating (highest temperature 46.5 ℃) is more effective than that of low temperature heating (highest temperature 35.3 ℃). That is to say, the dewater volume of the former is 2.2 (2.53/1.15) times higher than the latter while the rice cracking of the latter is 5 (2.5/0.5) times higher than the former . Therefore, it is very important to ensure the quality and its viability of rough rice for rational trying technological process.
