花生仁薄层干燥试验研究

A Study on Thin-layer Drying of Peanut Kernels

通过花生仁薄层干燥试验,探讨了风温、风速、相对湿度等参数对花生仁干燥速率的影响。分析结果表明:风温是影响干燥速率的主要因素。其次是风速,而相对湿度和物料初始水分影响则很小。同时,根据试验分析还建立了干燥速率的数学模型。

A test of thin-layer drying for peanut kernels has been taken. The test indicates that the drying rate of peanut kernels was affected by air temperature, wind speed, air relative humidity and initial moisture content of kernels. The results show that air temperature is the greatest effect on drying rate, the velocity of air the second one, then the initial moisture content of the kernels and the air relative humidity the smallest effect. A mathematical model has been formulated for thin-layer drying of peanut kernels.
