Example Embodiment

[0053] Example

[0054] In order to confirm the bactericidal effect of the present invention, the following experiments were carried out.

[0055] As a container to be sterilized in the experiment, a 500-ml PET bottle was used, and after the container was sterilized using the three-fluid nozzle described in FIG. 1 , the container was washed with warm water.

[0056] As sample bottles to be sterilized, ten 500-ml PET bottles were prepared. As the test bacteria, adjust the suspension of Bacillus subtilis var. niger NBRC13721 to the specified concentration, spray the inside of each sample bottle with 0.3ml of each bottle, and make the concentration reach 10 5 cfu / piece, make the bacterial suspension adhere to the inside of each bottle (initial bacterial count is 1.0×10 5 cfu / piece).

[0057] After the bacteria suspension was adhered, each bottle was stored in a clean room (class 10,000) for 24 hours to dry the inside of the bottle.

[0058] During sterilization, 30% hydrogen ...

Abstract

For reducing time required for sterilizing a container by hydrogen peroxide, mitigating a cost required therefore, simplifying a sterilizing apparatus, reducing space for installing such apparatus, and mitigating load to the environment, a method for sterilizing a container is provided according to which hydrogen peroxide aqueous solution, air at the normal temperature and hot air are simultaneously injected into a container whereby the hydrogen peroxide aqueous solution which has been turned to minute droplets by the air at the normal temperature is instantly gasified.

Description

technical field [0001] The present invention relates to a method of sterilizing polyester containers such as PET bottles and other containers, and a 3-fluid nozzle used in the sterilizing method. Background technique [0002] The aseptic filling system sterilizes containers such as bottles suitable for filling beverages and beverages, and fills and seals beverages in sterilized containers in an aseptic environment. As a method of sterilizing a container, a method of washing the container with sterile water or hot air after sterilizing the container with an aqueous solution of peracetic acid or hydrogen peroxide mist is widely used. In the aseptic filling system, although the amount of chemical solution and sterile water for cleaning is determined by the pipeline structure, as the pipeline speed increases, the amount of chemical solution and sterile water supplied to the pipeline per unit time increases, resulting in Increases in initial costs and operating costs, enlargemen...
