摘要
三七是我国名贵的中药材。干燥作为保证三七品质的重要措施,其干燥是一个伴随着三七本身物质化学变化的传热传质过程。本文通过进行三七热风恒温和分阶段干燥试验,观察三七外观和质量的变化情况,分析参数变化对三七外观和质量的影响,并根据各干燥测定结果,确定三七热风干燥方法最佳参数组合,提出热风干燥的优化方案。
The Panax Notoginseng is a precious traditional Chinese medicine. Drying is an important measure to ensure the quality of the Panax Notoginseng, and its drying is a complex process which includes heat and mass transmission and is accompanied by material and chemical changes. Through performing the hot-air constant temperature and phase drying experiments of Panax Notoginseng, this paper observes the changes of appearance and quality, and analyzes the effects that parameter change makes to the appearance and quality. According to various drying results, it determines the best parameter combination of Panax Notoginseng＇s hot-air drying,and puts forward the optimization program of hot-air drying.
