摘要
对羟丙基瓜尔胶(HPG)进行了常压干燥和真空干燥实验,对不同干燥条件下干燥过程中的水分变化情况进行研究,分析干燥过程、干燥机理及不同的干燥时间、温度对干燥的影响,最终确定了最佳的干燥条件,为生产过程中HPG水分的分析提供了理论参考。
In this paper, the vacuum drying,normal pressure drying on HPG is experimented. The moisture-loss condition of hydroxypropyl guar gum at different condilions is studied, analyze drying process .mechanism, and different drying time and drying lemperature influence on drying, the optimal drying condition was established finally, and an method which is for moisture analysis in manufacture process is offered.
