Steam sterilizing system for powdery materials

Abstract

The invention discloses a steam sterilizing system for powdery materials. The system comprises a dry heat sterilization mechanism used for providing hot air, a wet heat sterilization mechanism used for providing hot steam, a sterilization chamber, a feeding mechanism, an unloading mechanism, and a regulation mechanism used for providing all operating parameters for the system. The system can increase the sterilization efficiency, and can enable the material not to be influenced by steam humidity, thus guaranteeing the quality of the materials after sterilization.

Description

technical field [0001] The invention relates to the field of sterilization, in particular to a sterilization system for powdery materials in the food and pharmaceutical fields. Background technique [0002] Sterilization technology is to kill or remove the vegetative cells and their spores (or spores) of all microorganisms in the target object by physical and chemical means, so as to achieve the purpose of sterility. Sterilization technology is a necessary condition for obtaining pure culture of the target object, and it is an indispensable technology for ensuring the safety of food and medicine in the food industry and the field of medicine (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 different sterilizing agents, sterilization techniques are mainly divided into chemical reagent sterilization, radiation s...

Problems solved by technology

[0005] First, cobalt 60 radiation sterilization, the principle is to use high-energy electromagnetic waves to act on bacteria to produce biological effects to inhibit or kill bacteria, viruses, fungi and parasites, etc. There are still some doubts about the safety of medicines and food after sterilization, so this method has been canceled by some countries and regions;

[0006] Second, ethylene oxide sterilization, the use of ethylene oxide as a sterilant can effectively kill bacteria on the surface of the material, but after this method is sterilized, there will be sterilizers on the surface of the material, and the residue of sterilizers will affect the material There are potential safety hazards in the subsequent use and consumption of these residues, and the waste liquid obtained after removing these residues will pollute the environment;

However, moist heat sterilization is not suitable for sterilizing materials with high humidity, and while effectively achieving the purpose of sterilization, it must be heated for a long time, and after the above-mentioned long-term sterilization treatment, due to the difference in steam humidity, It is very easy to cause changes in the color, fragrance and active ingredients of the processed product, affecting the quality and value of the product
