Method for powder disinfection and apparatus thereof

Abstract

A method for disinfecting the powdered material includes such steps as feeding the powdered material in a mixing cabin, introducing the pressurized disinfecting air containing ozone to the mixing cabin to blow up the powdered material for sufficient contact between powdered material and disinfecting air, and filtering for cyclic use of disinfecting air. Its apparatus is composed of a mixing cabin, a pressurized disinfecting air generator, a filter and the connecting pipelines.

Description

technical field [0001] The invention relates to a method and a disinfection device for sterilizing object powder, in particular to a method and a disinfection device for sterilizing by fully contacting disinfection gas with object powder. technical background [0002] At present, there are several methods to sterilize the powder, such as steam sterilization, microwave sterilization and radiation sterilization. Steam disinfection is to use the high temperature of water vapor to sterilize the powder in a high-pressure container. The high temperature, high pressure and high humidity environment will have a great impact on the disinfection object. For example, when disinfecting traditional Chinese medicine powder, the active ingredients of the traditional Chinese medicine powder will be It is greatly damaged, greatly reducing the efficacy of traditional Chinese medicine products; when sterilizing condiments, dehydrated vegetables, tea leaves, etc., their taste will be greatly re...

AI Technical Summary

Problems solved by technology

Steam disinfection is to use the high temperature of water vapor to sterilize the powder in a high-pressure container. The high temperature, high pressure and high humidity environment will have a great impact on the disinfection object. For example, when disinfecting traditional Chinese medicine powder, the active ingredients of the traditional Chinese medicine powder will be It is greatly damaged, greatly reducing the efficacy of traditional Chinese medicine products; when sterilizing condiments, dehydrated vegetables, tea leaves, etc., their taste will be greatly reduced; using steam to sterilize chemical raw materials can easily cause chemical changes in chemical raw materials, resulting in chemical raw material denaturation

When using steam to sterilize, the sterilized object is easy to agglomerate after disinfection, and must be crushed and sieved, which will inevitably cause secondary pollution

In addition, the use of steam disinfection must be equipped with boilers and steam pipelines, and the energy consumption and operating costs are relatively high

Microwave disinfection is a high-temperature disinfection using microwave heating. The high-temperature environment has a great impact on the disinfection objects. The active ingredients of traditional Chinese medicine powder are greatly damaged, which reduces the efficacy of traditional Chinese medicine products, and the taste of condiments, dehydrated vegetables and tea leaves is also great. Discount, the high temperature environment will also cause denaturation of chemical raw materials, and the side effects of microwave radiation on workers are also great

Irradiation disinfection is to use the radiation of radioactive elements to complete disinfection. Its disadvantages are: 1. Lipid-rich disinfection objects are highly variable during the irradiation process, which reduces the use value of disinfection objects and even produces toxic substances; 2. Irradiation costs Higher, generally 1,000 yuan / ton, so the cost of disinfection is high
