Abstract

The invention discloses a sterilization method for improving the safety performance of traditional Chinese medicinal materials, which comprises the following steps: 1) washing and drying the traditional Chinese medicinal materials and cutting them into sections, and evenly drawing notches on the wall surface of the traditional Chinese medicinal materials; 2) putting the medicinal materials in 1) into 3) put the medicinal materials into the ultraviolet sterilization chamber for ultraviolet irradiation; 4) put the 3) Chinese medicinal materials into cloth bags, put them into the sterilization box, and pass through ethanol steam; 5) put the medicinal materials into Put it into a vacuum bag and vacuum seal it. The Chinese medicinal material sterilization method of the present invention is easy to operate, can be carried out continuously, has high production efficiency and low labor intensity, can effectively kill bacteria and microorganisms in the medicinal material, has good sterilization effect and does not damage the properties of the traditional Chinese medicine. Through the collaborative work of multiple processes such as pressure cooker, ultraviolet sterilization, and ethanol sterilization, the sterilization effect on the surface of medicinal materials can be greatly improved. By making a gap on the surface of medicinal materials, the sterilization medium can fully contact with the interior of Chinese medicinal materials. Improve the quality of sterilization.

Example Embodiment

[0014] Example 1
[0015] The sterilization method to improve the safety performance of Chinese medicinal materials includes the following steps: 1) After the Chinese medicinal materials are selected, they are washed, dried and cut into sections, and then 2-3mm long gaps are evenly marked on the wall of each section of Chinese medicinal materials; 2) Put the medicinal materials in step 1) into the pressure cooker, fill the pressure cooker with an appropriate amount of water, place the medicinal materials on the steaming plate of the pressure cooker, and steam for 20-30 minutes; 3) take out the medicinal materials in step 2) and put them into ultraviolet sterilization UV irradiation is carried out indoors, the temperature in the sterilization room is 25-30℃, and the duration is 3-4h; 4) Put the traditional Chinese medicinal materials after UV sterilization in step 3) into a cloth bag, and then put it into the sterilization box. Ethanol steam is introduced into the sterilization box; 5) the medicinal materials in step 4) are put into a sterile vacuum bag, vacuumed, and then sealed and packaged.
[0016] The method for sterilizing Chinese medicinal materials has simple operation, can be performed continuously, has high production efficiency and low labor intensity, can effectively kill bacteria and microorganisms in medicinal materials, has good sterilization effect and does not damage the medicinal properties of Chinese medicine. Through the collaborative work of multiple processes such as autoclave, ultraviolet sterilization, ethanol sterilization, etc., the sterilization effect of the surface of the medicinal material can be greatly improved. By notching the surface of the medicinal material, the sterilization medium can be fully contacted with the inside of the Chinese medicinal material. Improve the quality of sterilization.
[0017] Preferably, the cloth bag is a cloth bag that does not shed fibers, so as to prevent fibers from sticking to the medicinal materials.
[0018] Preferably, after step 3), it further includes putting the medicinal materials into the microwave tunnel of the microwave drying and sterilizing machine for sterilization, and the sterilization time is controlled within 10-15 minutes.
[0019] Preferably, in step 4), the temperature in the sterilization box is raised to 50-60°C, and the duration of the introduction of ethanol vapor is 10-15 minutes.
[0020] Preferably, the vacuum bag is filled with dry ice to facilitate the storage of medicinal materials.
