A powder and granular body superheated steam sterilization process and system

Abstract

The invention discloses a technology and a system of powder body superheated steam sterilization, and belongs to the field of material sterilization and drying. The technology comprises the following steps: (1) adding a powder body material steam into a superheated steam stream; (2) controlling the superheated steam stream to form a cyclone stream, so that the material is dispersed in the cyclone stream, and utilizing the steam heat for sterilization for 3-10 seconds, and controlling the sterilization temperature within the range of 120-250 DEG C; (3) causing the steam stream to form cyclone stream, and utilizing the centrifugal force to separate the material and the steam stream; (4) utilizing the dried hot wind to dry the material, and utilizing dried cold air to cool the dried material; (5) performing steam and temperature compensation on the steam stream in the step (3), and participating in the superheated steam stream feeding technology in the step (1). The invention further discloses a system of powder body superheated steam sterilization. According to the invention, the technology is convenient in operation and simple in device structure, realizes automatic and continuous sterilization production, is low in consumption for sterilization, and is greatly increased in production efficiency.

Description

Technical field [0001] The invention relates to a sterilization process and system, and more specifically, to a powder and granular superheated steam sterilization process and system. Background technique [0002] For the sterilization of powders and granules, there are generally two types of non-heat sterilization and heat sterilization. Non-heat sterilization methods also include pharmaceutical sterilization, ozone sterilization, radiation sterilization and ultraviolet sterilization. Pharmaceutical sterilization generally uses ethylene oxide, propylene oxide and other drugs for sterilization. However, although these drugs have effects on most microorganisms Sterilization ability, but even if the sterilization conditions are optimized, a long sterilization time is required, and there are problems such as the possibility of carcinogenesis or quality deterioration due to the residue of the drug, so it is difficult to realize practical use; the ozone sterilization method except for...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the shortcomings of the existing powder and granular body that the sterilization effect is not ideal and it is difficult to realize continuous automatic production, and to provide a powder and granular body superheated steam sterilization process and system. The technical scheme of the present invention is adopted, the process is convenient to operate, and the device The structure is simple, the cost is low, and the automatic continuous sterilization production is realized, and the finished product does not agglomerate and can be directly packaged; at the same time, the energy consumption of sterilization is low, and the production efficiency is greatly improved
