Method for sterilizing surface of space and sterilization system

Abstract

Provided are a method and a device for sterilizing the surface of a space-to-be-sterilized which are safe to the human body, which are effective even for sterilizing spore-forming bacteria, which do not require the space-to-be-sterilized to be highly shielded, and which can sterilize the surface of the space efficiently with inexpensive equipment. The disclosed method involves: spraying a low-concentration sterilizing agent in the form of fine particles into the space-to-be-sterilized and making the sterilizing agent adhere to the surface thereof, the low-concentration sterilizing agent being any one of a 1-10 wt% aqueous solution of hydrogen peroxide, a 0.1-1 wt% aqueous solution of peracetic acid, or a 0.01-0.1 wt% aqueous solution of hypochlorous acid; adjusting the humidity in the space-to-be-sterilized; and air-drying the sterilizing agent. Thus, a high level of sterilization can be achieved in a short time and at low cost.

Description

technical field [0001] The present invention relates to a sterilizing method and sterilizing system for the surface of a space using a bactericide in a space requiring sterility or cleanliness, such as container manufacturing such as sanitary bottles facing aseptic filling lines for beverages and foods, and medical manufacturing plants. Background technique [0002] In the manufacture of containers such as sanitary bottles for aseptic filling of beverages and foods, and medical manufacturing plants, etc., the manufacturing equipment, the surface of the container, and the surface of the room, etc., which are in direct or indirect contact with the container or product (hereinafter, collectively referred to as For the space surface), usually requires a high degree of cleanliness. Space surface sterilization technology, especially in the manufacture of containers such as sanitary bottles for aseptic filling, is an old and new technology that is indispensable. Although various me...

AI Technical Summary

Problems solved by technology

Therefore, various methods of sterilizing the sprayed sterilant by vaporizing them have been proposed as mentioned above as conventional space surface sterilization. In the past, it has hardly been put into practical use, and the space sterilization using chemicals generally adopts the method of directly spraying or spraying the sterilizing agent aqueous solution on the object to be sterilized, and then washing it with sterile water, etc.

However, in this case, there are problems such as that it cannot be applied to the object to be sterilized in a wet state, and the sterilizing efficiency is also poor, requiring a large amount of bactericide and washing water.

In addition, when only the fungicide is attached and the fungicide is naturally dried, it takes a long time to completely remove it, and the above-mentioned problems (5) and (6) occur.
