Method for steam sterilization of rare and precious medicinal materials

Abstract

The invention discloses a method for the steam sterilization of rare and precious medicinal materials, which comprises: opening a pulse control valve connected with a sterilization chamber to introduce superheated steam into the sterilization chamber, wherein the superheated steam is changed into pulse superheated and sterilized steam after passing through the pulse control valve; and introducingthe pulse superheated and sterilized steam to the sterilization chamber from the hot air inlet of the sterilization chamber, and performing pulse blowing of the materials to be sterilized in the chamber for 1 to 60 seconds, wherein the steam passes through a preheating system before the sterilization. The invention solves the problem of the steam sterilization method in the prior art that the rotation of a stirrer for uniform and complete sterilization causes damages to the materials to be sterilized and influences the medicinal value of the materials to be sterilized by providing the method for the steam sterilization of the rare and precious medicinal materials which can ensure the materials are neither damaged nor affected in medicinal value.

Description

technical field [0001] The invention relates to a sterilization method, in particular to a steam sterilization method for rare medicinal materials such as cordyceps. Background technique [0002] Sterilization technology belongs to the basic technology of microbiology, which uses physical and chemical means to kill or remove the vegetative cells and their spores (or spores) of all microorganisms in the culture medium, fermentation equipment or other targets, so as to achieve the purpose of sterility. Sterilization technology is a necessary condition for culture medium, fermentation equipment or other target substances to obtain pure culture, and it is an indispensable technology to ensure food and drug safety in the food industry and pharmaceutical fields (especially in the field of traditional Chinese medicine production). [0003] The thoroughness of the sterilization technique depends on the two parameters of sterilization time and sterilant strength. According to differ...

AI Technical Summary

Problems solved by technology

[0007] For this reason, the technical problem to be solved by the present invention is that the steam sterilization method in the prior art uses the agitator to rotate during sterilization to ensure uniform and thorough sterilization, but the material to be sterilized is damaged and its medicinal value is affected. , so as to propose a steam sterilization method for rare and precious medicinal materials that can effectively ensure that the materials will not be damaged and will not affect their medicinal value
