Method for realizing and maintaining sterile environment of sterile filling isolation bin

Abstract

The invention provides a method for realizing and maintaining a sterile environment of a sterile filling isolation bin, which comprises the following steps: spraying a peracetic acid solution into the isolation bin to sterilize the isolation bin, and then introducing first vaporized hydrogen peroxide into the isolation bin to fumigate the isolation bin, and introducing sterile dry hot air into the isolation bin to keep the isolation bin dry. The peracetic acid solution is sprayed into the isolation bin, so that the isolation bin can be primarily sterilized and disinfected, the residual stabilizer in the isolation bin can be removed, and the condition of scaling in the isolation bin is effectively prevented; and the method has the advantages of simple process, good sterilizing effect, high sterilizing efficiency and good stability.

Description

technical field [0001] The invention relates to an aseptic filling production line, in particular to a method for realizing and maintaining the aseptic environment of an aseptic filling isolation warehouse. Background technique [0002] With the continuous development of aseptic filling production line, the use of aseptic filling production line is more and more recognized by customers. The use of the aseptic filling production line can not only maintain the original characteristics, taste and nutritional value of the product as much as possible, and is more easily accepted and favored by consumers, but also can avoid product contamination and further improve the shelf life of the product. [0003] Sterilizing the aseptic filling isolation warehouse is the key to ensure the aseptic environment. As a bactericide, peracetic acid has strong oxidizing properties, and its sterilizing effect is good, but it is easy to have acid residue, and it needs to be washed with a large amou...

AI Technical Summary

Problems solved by technology

As a bactericide, peracetic acid has strong oxidizing properties, and its sterilizing effect is good, but it is easy to have acid residues. After sterilization, it needs to be washed with a large amount of sterile water, which is costly and not environmentally friendly.

Hydrogen peroxide is cheap and has a good sterilizing effect. At present, hydrogen peroxide is generally used for sterilization. However, due to the instability of hydrogen peroxide, it is easily decomposed by heat and light, which greatly reduces the sterilizing effect.

In order to reduce the decomposition of hydrogen peroxide and ensure the sterilization effect, stabilizers are generally added to hydrogen peroxide. If hydrogen peroxide containing stabilizers is used for sterilization for a long time, it is easy to scale in the isolation chamber and pipeline, which is not conducive to non-toxic Sustained maintenance of bacterial environment
