  • the sterilization is performed such that both surfaces of the above-mentioned glass tube are sufficiently contacted with a heating solution for sterilization, for example, a hydrogen peroxide solution. That is, in the first stage, the heat sterilization solution naturally falls in the heating space between the heat sterilization solution storage tanks while sufficiently spreading the band-shaped tube. At the same time, the above-mentioned condition-bubble is simultaneously moved vertically downward in the space filled with the heat sterilization solution, and is continuously sterilized at a constant high temperature. The sterilizing solution is supplied in such a manner that it always overflows into this space, so that both surfaces of the tape are kept at a predetermined temperature.

Abstract

Appareil permettant de stériliser une feuille souple en continu analogue à une bande, telle qu'un film de conditionnement en continu passant dans une zone humide. Cet appareil est constitué de sorte que la stérilisation de la feuille en continu s'effectue lorsque celle-ci est amenée en contact, dans des espaces étroits, avec une solution de stérilisation chauffée. Ces espaces étroits de stérilisation sont ménagés dans l'appareil de manière à amener la feuille en contact avec la solution de stérilisation en déplaçant ladite feuille dans le sens d'écoulement de la solution, et à amener ensuite la feuille en contact avec la solution en la déplaçant dans le sens opposé au sens d'écoulement de la solution.
