水分在线检测技术及其在中药干燥领域应用展望

干燥是中药生产过程中最常见的单元操作之一,中药物料干燥伴随着含水率减小的动态过程。物料含水率作为干燥过程终点判定的关键指标,在干燥效率提升、能源节约方面发挥着重要作用。目前,中药干燥生产过程基本通过取样离线检测对物料含水率进行监控,鲜有在线水分检测技术应用报道。该文介绍了不同领域物料干燥过程在线检测技术的原理和应用现状,分析了在线检测技术在中药干燥中的重要意义,展望了在线检测技术在中药干燥领域应用前景。在中药制造业亟待转型升级的大背景下,水分在线检测技术的应用有望成为中药干燥工艺和装备智能化升级的关键突破口。

Online moisture detection technology and its application prospect in drying of traditional Chinese medicine

Drying is one of the most common unit operations in the production of traditional Chinese medicine.The drying process of traditional Chinese medicine materials is accompanied by the dynamic reduction of water content.As a key index to determine the end of the drying process,the moisture content of materials plays an important role in improving drying efficiency and saving energy.Recently,the drying process of traditional Chinese medicine is mostly monitored by offline detection,and there are few reports of online moisture detection applications.In this paper,the principle and current application of online inspection technology for the material drying process in different fields were introduced.The significance of online detection technology in drying of traditional Chinese medicine was also analyzed.Meanwhile,the application prospect of online detection technology in the field of drying of traditional Chinese medicine was predicted.In response to urgent transformation and upgrading of the traditional Chinese medicine manufacturing industry,the application of online moisture detection technology is expected to be a key breakthrough in the intelligent upgrading of traditional Chinese medicine drying technology and equipment.
