ヒドロラジカルになる。(Effects of the Invention) As described above, in the container sterilization method of the present invention, ozone water and approximately equivalent amount of hydrogen peroxide solution (or peracetic acid aqueous solution) are first mixed. This ozonated water and hydrogen peroxide solution become hydroradicals with strong sterilizing power within a short period of several seconds to 20 seconds after being mixed.
この混合直後のオゾン水と過酸化水素水とを噴射ノズル
から被殺菌容器へ噴射して、被殺菌容器の内外面を殺菌
し、その前後にオゾン水を必要に応じ被殺菌容器へ噴射
して、過酸化水素水または過酢酸水溶液の除去を行うの
で、前記従来のように殺菌処理部とリンス部とのそれぞ
れに殺菌装置を設ける必要がなくて、装置スペースを節
減できる。Immediately after mixing, the ozonated water and hydrogen peroxide solution are injected from the injection nozzle into the container to be sterilized to sterilize the inside and outside surfaces of the container to be sterilized, and before and after that, ozonated water is injected into the container to be sterilized as necessary. Since the hydrogen peroxide solution or the peracetic acid aqueous solution is removed, there is no need to provide a sterilization device in each of the sterilization processing section and the rinsing section as in the conventional method, and the device space can be saved.
また前記従来のように殺菌処理部とリンス部との間で行
っていたハンドリングを不用にできて。Moreover, the handling that was performed between the sterilization processing section and the rinsing section as in the conventional method can be made unnecessary.
無菌維持を容易に行うことができる。Sterilization can be easily maintained.
またオゾン水と過酸化水素水とを混合させて。Also, mix ozone water and hydrogen peroxide solution.
強力な殺菌力を持つ安全性の高いヒドロラジカルにする
ので、比較的濃度の高い殺菌剤を不用にできる上に１リ
ンス水を節減できる効果がある。Since it is a highly safe hydroradical with strong bactericidal activity, it is possible to eliminate the need for relatively highly concentrated bactericides and also to save water per rinse.
