Description

Microwave Sterilization Device for Chinese Herbal Pieces and Crushed Materials

technical field

The utility model relates to a sterilizing device for Chinese medicinal materials, in particular to a microwave sterilizing device for decoction pieces of traditional Chinese medicine and pulverized materials.

Background technique

Since the state promulgated the "Pharmaceutical Hygienic Standards" in 1978, the problem of sterilization of traditional Chinese medicines has been a problem that all Chinese patent medicine manufacturers, especially those that use a large amount of raw materials for direct crushing and preparation, must face the problem. In the whole process of traditional Chinese medicine production, the channels that cause microbial contamination mainly include the following two aspects: ①The main raw materials used—Chinese herbal medicines will cause pollution during the process of planting, harvesting, drying, storage, and processing; ②The crushing of Chinese herbal medicines Pollution from processing.

The existing sterilization methods used in the production process of traditional Chinese medicine are as follows: ① damp heat steam sterilization; ② microwave sterilization; ③ Co ⁶⁰ irradiation sterilization. (The other two sterilization methods: ethylene oxide sterilization and ozone sterilization are rarely used because they cannot be used in the large-scale production of traditional Chinese medicine.) The above three methods are currently widely used in the production of traditional Chinese medicine. , all have their own disadvantages or imperfections, which will ultimately affect the stability of Chinese patent medicine product quality, the strict implementation of drug production GMP regulations, energy saving and consumption reduction and other issues: ①Moist heat steam sterilization can be used to sterilize raw materials , the effect is better, but the effect on the active ingredients in Chinese medicinal materials, especially the volatile ingredients and heat-sensitive ingredients is particularly prominent. In addition, when the moist heat sterilization method is used to sterilize a large number of traditional Chinese medicines, the energy consumption is large; ② Ordinary microwave The sterilization method used for medicinal materials has a poor sterilization effect, and different forms of medicinal materials absorb microwave energy differently, resulting in poor sterilization uniformity. The use of microwaves in the final sterilization of preparations has certain effects, but according to the requirements of the GMP standard for drug production, the crushing of medicinal materials and the preparation process are required to be carried out in clean workshops. If the medicinal materials themselves are not sterilized, they enter the clean workshop for processing It will affect the standard operation of GMP workshop. ③ Co ⁶⁰ irradiation sterilization has a better sterilization effect on various forms of materials, but Co ⁶⁰ irradiation sterilization will also cause damage to many components in traditional Chinese medicine. Therefore, it is very necessary to seek a new method of sterilization of traditional Chinese medicine, which can effectively sterilize the Chinese medicine, retain the ingredients of the traditional Chinese medicine to the greatest extent, improve the product quality and curative effect of the traditional Chinese medicine, and meet the requirements of the GMP standard.
