天麻热风干燥试验分析

Analysis on Hot-air Drying Test of Gastrodia Elata

天麻是我国名贵的中药材。干燥作为保证天麻品质的重要措施,其干燥是一个伴随着天麻本身物质化学变化的传热传质过程。文章通过进行天麻热风干燥试验,观察天麻外观和质量的变化情况,分析参数变化对天麻外观和质量的影响,并根据各干燥测定结果,确定天麻热风干燥方法最佳参数组合,提出热风干燥的优化方案。

Gastrodia elata is a precious traditional Chinese medicine. Drying is an important measure to ensure its qualityand its drying is a complex process containing heat and mass transmissionI, and accompanied by material and chemical changes. After hot-air drying test for Gastrodia elata, this paper observes the changes in its appearance and quality, and analyzes the effects of parameter change on its appearance and quality. According to various drying results, it determines the best parameter combination of Gastrodia elata’s hot-air drying method,and puts forward the optimization program of hot-air drying.
