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.
干燥是中药生产中最常见的单元操作之一。中药材的干燥过程伴随着含水量的动态降低。作为确定干燥过程结束的关键指标，物料的含水量对提高干燥效率和节约能源起着重要作用。近年来，中药干燥过程大多通过离线检测进行监测，关于在线水分检测应用的报道较少。本文介绍了不同领域物料干燥过程在线检测技术的原理及当前应用情况。还分析了在线检测技术在中药干燥中的意义。同时，对在线检测技术在中药干燥领域的应用前景进行了预测。针对中药制造业迫切的转型升级需求，在线水分检测技术的应用有望成为中药干燥技术与装备智能化升级的关键突破口。
