| 摘 要： | 研究了一定条件下风速与风温对经烫漂预处理的洋葱薄层热风干燥过程的影响,拟合了干燥曲线方程,并计算了临界含水量、传热膜系数α与传质系数kH等动力学参数。结果表明:干燥方程符合Page模型;随风速增大α与kH均增大,但风温对两者影响不大。

| Abstract: | It have been studied that the influence of the wind speed and temperature on the dry course of thin layer of the onion by pretreatment with hot air under certain condition. The dry curve equations were fitted , the dynamics parameter, such as the critical water content, heat transmission membrane coefficient a, and quality transmission coefficient kH, were calculated. The result shows that the dry equation accords with the Page model. As the wind speed rises, a and kH were increased, but the wind temperature has a little effect on the two coefficient. |
