Sterilizing method for low temperature steam sterilized traditional Chinese medicine

Abstract

The invention provides a sterilizing method for low temperature steam sterilized traditional Chinese medicine, and relates to the technical field of traditional Chinese medicine sterilizing methods. The sterilizing method comprises the following steps: placing traditional Chinese medicine into a sterilizing room; vacuuming the sterilizing room; introducing high-temperature and high-pressure steam into the sterilizing room; when the pressure in the sterilizing room reaches a sterilizing pressure, preheating for stabilizing; continually introducing high-temperature and high-pressure steam, so that the temperature in the sterilizing room rises to a sterilizing temperature; starting sterilization; entering a drying process after finishing the sterilization; drying and standing for 24 hours to wait for the growth of spores; sterilizing once again; repeating the waiting and sterilizing processes after finishing the sterilization; finishing the sterilization. The sterilizing method is convenient to run, energy consumption is lowered greatly, and the original efficacy, characteristic and uniformity of the traditional Chinese medicine are kept; meanwhile, a plurality of bacteria such as molds and escherichia coli in traditional Chinese medicinal powder are killed fully, and a large amount of energy and material resource cost is saved; the sterilizing method is a novel and environment-friendly sterilizing method being worthy of wide popularization.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine sterilization methods, in particular to a sterilization method for low-temperature steam sterilization of traditional Chinese medicines. Background technique [0002] The new version of the "Good Manufacturing Practice for Drugs" promulgated by the State Food and Drug Administration has made detailed regulations on the sterilization operations of traditional Chinese medicine and its preparations. The "Chinese Pharmacopoeia" also put forward strict requirements for the microbial limit inspection of traditional Chinese medicine and its preparation , Sterilization operation, as a key operation unit affecting the quality of traditional Chinese medicine and its preparations, will directly affect the safety, effectiveness and quality stability of medicines. At present, the current situation of sterilization of traditional Chinese medicine is not to sterilize or use high temperature ...

AI Technical Summary

Problems solved by technology

At present, the current situation of sterilization of traditional Chinese medicine is not to sterilize or use high temperature and high pressure steam to sterilize. For traditional Chinese medicine that is not sterilized, the Chinese medicinal materials are directly washed and dried, and then crushed in a crusher and filtered to form traditional Chinese medicine powder. The powder is directly packaged and sold. Although it can maintain the efficacy and properties of the original traditional Chinese medicine, it is prone to mildew due to the presence of miscellaneous bacteria (such as molds, Escherichia coli, etc.) and the growth of other bacteria, resulting in harmful pathogens in the medicine, resulting in Drugs contain different strains of bacteria that have different effects, and the uniformity of drug properties cannot be achieved; high-temperature and high-pressure steam sterilization uses high-temperature and high-pressure steam to sterilize and dry Chinese medicine, and put sterile Chinese medicine powder in the sterile area After being packaged and sold, this method can maintain the uniformity of the original Chinese medicine powder. However, after the high-temperature treatment of the medicine powder, the sugar-containing part will be gelatinized, and a series of chemical reactions may occur in other parts due to high-temperature and high-pressure steam treatment, resulting in sterilized Chinese medicine powder. The actual content and composition of the drug have changed a lot, and the original efficacy of traditional Chinese medicine cannot be maintained.
