干燥参数对稻谷热风干燥速率及能耗的影响
Influence of Drying Parameters on Hot Air Drying Rate and Energy Consumption of Rice
摘要
Abstract
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 5 565.03 kJ·kg-1.Therefore,optimizing the drying process and drying parameters not only improved the drying rate but also reduced drying energy consumption.关键词
