摘　　要：[目的]研究滇重楼热风干燥过程中不同因素水平对其干燥效果的影响,为滇重楼热风干燥工艺的优化和改进提供理论依据。[方法]以滇重楼为试验材料,设计并完成滇重楼干燥正交试验,分析在温度、风速和铺料密度等因素变化的情况下,滇重楼外观品质和水分的变化情况,探讨各种因素水平对其干燥效果的影响。[结果]影响滇重楼干燥效果的主次因素排序为温度>风速>铺料密度>相对湿度,其中干燥温度55℃、风速0.7 m/s、铺料密度4 kg/m2、相对湿度40%的条件下,干燥得到的重楼外观品质最佳。[结论]采用热风干燥技术得到的重楼成品整体质量比较高,且热风干燥具有能耗低、所需设备简单等优点,在滇重楼规模化生产过程中值得推广应用。[Objective] The aim was to study the drying effect of different factors and levels on Paris polyphylla and provide theoretical basis for hot-air drying technique optimization and improvement. [Method]With P. polyphylla as test material,drying orthogonal test was designed and completed,the variation of appearance quality and moisture was analyzed with the change of temperature,wind speed,paving density,effects of each factor on drying process were discussed. [Result] The order of main influencing factors was temperature wind speed paving density relative humidity. Under the conditions of temperature 55 ℃,wind speed 0. 7 m / s,paving density 4 kg / m2,relative humidity40%,the appearance quality of P. polyphylla was best. [Conclusion] Using hot-air drying technology can obtain high-quality P. polyphylla with advantages of low energy consumption,simple equipment and so on,which is worthy of popularization in large-scale production of P.polyphylla.
