Embodiment 1

[0043] figure 1 A schematic diagram of the steam sterilization device according to the present invention is provided, and it can be seen from the figure that the steam sterilization device includes a sterilization chamber 6 and a cooling chamber 21; a sterilization chamber is arranged on the sterilization chamber 6 The feed inlet 30 and the sterilization chamber discharge port 31 are also provided with a hot air inlet 24 on the sterilization chamber 6, and the superheated sterilization steam enters the sterilization chamber 6 through the pulse control valve 1 through the hot air inlet 24 Inside. A gas discharge port 29 is also provided on the sterilization chamber 6, and the gas discharge port 29 is arranged outside the sterilization chamber 6. In this embodiment, it is located on the upper part of the sterilization chamber 6, through which the gas The switch of the discharge port 29 realizes the discharge of hot steam and hot air inside the sterilization chamber 6 .

Embodiment 2

[0047] The steam sterilizer described in this embodiment is as figure 2 As shown, the hot air inlet 24 is also provided with a first branch air inlet 25 and a second branch air inlet 26, and the first branch air inlet 25 communicates with the heat through the first passage 51 of the three-way control valve 5. The heat exchanger 3 is connected, and the second branch air inlet 26 is connected with the heat exchanger 3 through the pulse control valve 1, and the heat exchanger 3 is connected with the hot air induced draft fan 2 and the steam generator 4, and the three-way control valve The second passage 52 communicates with the hot air induced fan 2 .

[0048] When the steam sterilizer in this embodiment is working, it is first necessary to open the gas discharge port 29, and at the same time open the hot air induced draft fan 2 and the first passage 51 of the three-way control valve, through which the hot air induced draft fan 2 can exchange heat The device 3 and the sterilizi...

Embodiment 3

[0051] The steam sterilizer described in this embodiment is as image 3 As shown, it is provided with a sterilization chamber shell 14 that forms an interlayer with the sterilization chamber 6 on the sterilization chamber 6, and fills the heat preservation medium in the interlayer, thereby reducing the sterilization process of the sterilization chamber 6 as much as possible. Neutralize the external energy exchange, thereby reducing the loss of high temperature and reducing energy consumption. In addition, a feed hopper 9 is further provided at the feed port 30 of the sterilization chamber, and the feed hopper 9 and the feed port 30 of the sterilization chamber are connected through a feed port control valve 8 to facilitate the addition of materials. Similarly, a control valve 15 for the discharge port of the sterilized chamber can be set between the discharge port 31 of the sterilized chamber and the feed port 32 of the cooling chamber to control the transfer of the sterilized...

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...
