Microwave sterilization process for traditional Chinese medicines

Abstract

The invention discloses a microwave sterilization process for traditional Chinese medicines. The microwave sterilization process comprises the following steps: (1) performing pretreatment, namely performing pretreatment on raw materials so as to obtain traditional Chinese medicines; (2) crushing, namely crushing the obtained traditional Chinese medicines into granules not greater than 5mm by usinga crushing machine; (3) performing microwave sterilization, namely performing sterilization treatment on crushed traditional Chinese medicine granules in a microwave sterilization tank, and conveyingthe sterilized traditional Chinese medicines for later use in next procedures, wherein the sterilization temperature is 60-80 DEG C, and the sterilization time is 30-60 minutes. The process disclosedby the invention is low in sterilization temperature and rapid in speed, and thus loss of effective components of medicines is reduced.

Description

technical field [0001] The invention relates to a microwave sterilization process for Chinese medicinal materials. Background technique [0002] Chinese herbal medicines will be polluted by the outside world during storage and transportation, and they must be sterilized before use. The sterilization methods commonly used in the production process of traditional Chinese medicines are: ①moist heat steam sterilization; ②microwave sterilization; ③Co60 radiation Sterilize. (The other two sterilization methods: ozone sterilization and ethylene oxide sterilization are rarely used because they cannot be used for large-scale production of traditional Chinese medicine). These sterilization methods have their own disadvantages or imperfections to varying degrees, which will ultimately affect the stability of the product quality of Chinese patent medicines, the strict implementation of GMP standards for drug production, and energy saving and consumption reduction: ① Moist heat steam st...

(The other two sterilization methods: ozone sterilization and ethylene oxide sterilization are rarely used because they cannot be used in large-scale production of traditional Chinese medicine)

These sterilization methods have their own disadvantages or imperfections to varying degrees, which will ultimately affect the stability of the product quality of Chinese patent medicines, the strict implementation of GMP standards for drug production, and energy saving and consumption reduction: ① Moist heat steam sterilization, commonly used It is good for the sterilization of raw medicinal materials; however, due to the cold air in the medicinal materials, the steam is not easy to penetrate, and it must reach a certain temperature and maintain a certain period of time to achieve the sterilization effect. On the one hand, high temperature can easily cause volatile components in the medicinal materials and heat-sensitive components are lost in large quantities. On the other hand, when used for sterilization of a large number of Chinese medicinal materials, the energy consumption is large

However, different forms of medicinal materials have different degrees of absorption of microwave energy, resulting in poor sterilization uniformity. In addition, the water content of sterilized materials is only about 10%, so the sterilization effect of ordinary microwave sterilization is poor.
