摘　　要：针对稻谷热风干燥过程中能量消耗高、干燥效率低的问题,以‘稻花香’稻谷为研究对象,测定各初始含水率下的稻谷在不同干燥参数下的干燥能耗和干燥效率,确定不同参数水平下的最优方案。多因素正交试验研究表明,对稻谷干燥速率的影响从强到弱为热风温度、热风风速、初始含水率。对单位干燥能耗的影响从强到弱为:热风温度、初始含水率、热风风速。最优的干燥参数为热风温度50℃、热风风速0.7 m·s^(-1)、初始含水率19%、干燥速率为5.28%·h^(-1)、干燥能耗为5 565.03 kJ·kg^(-1)。因此,优化干燥流程和干燥参数,既能提升干燥速率又可减少干燥能耗。Aiming at the problems of high energy consumption and low drying efficiency in the hot air drying process of rice.,taking‘Daohuaxiang’rice as the research object,the drying energy consumption and drying efficiency of rice at different initial moisture contents under different drying parameters were measured to determine the optimal plan at different parameter levels.The multi factor orthogonal experimental study showed that the influence on the drying rate of rice ranges from strong to weak were hot air temperature,hot air speed,and initial moisture content,respectively.The impact on unit drying energy consumption ranges from strong to weak were hot air temperature,initial moisture content,and hot air speed,respectively.The optimal drying parameters were hot air temperature of 50℃,hot air wind speed of 0.7 m·s^(-1),initial moisture content of 19%,drying rate of 5.28%·h^(-1),and drying energy consumption of 5565.03 kJ·kg^(-1).Therefore,optimizing the drying process and drying parameters not only improved the drying rate but also reduced drying energy consumption.
