传统中成药蜜丸、水泛丸、散剂等以中药原粉为主要成型原料,中药原粉(或称生粉)存在染菌问题,是影响中成药产品质量的重要因素之一。目前除了对药材进行净选冲淋除菌及在粉碎过程中减少污染之外,生粉灭菌已为人们所重视。中药生粉灭菌一般采用流通蒸汽灭菌、热压灭菌、远红外线干燥灭菌;设备有各式灭菌器、消毒柜、烘箱等。这些灭菌方法和设备各有利弊,并且在尔后的干燥或混和工序中都有重新污染的可能,在生产应用中未能尽如人意,因此设计中药粉灭菌器,如图。
Traditional Chinese medicines, such as Miwan Pills, Shuipan Pills, and Powders, use traditional Chinese medicine powder as the main raw material for molding, and the traditional Chinese medicine powder (or powder) has the problem of contamination, which is one of the important factors affecting the quality of proprietary Chinese medicines. At present, in addition to the net selection of herbs for rinsing and sterilizing and reducing pollution during the comminution process, the sterilization of raw powder has been paid attention to by people. The sterilization of traditional Chinese medicine powders generally adopts circulating steam sterilization, autoclave sterilization, and far-infrared drying sterilization; the equipment includes various types of sterilizers, disinfection cabinets, and ovens. These sterilization methods and equipment have advantages and disadvantages, and may be re-contaminated in the subsequent drying or mixing process, and are not satisfactory in production applications. Therefore, a traditional Chinese medicine powder sterilizer is designed as shown in the figure.
