Abstract:
1. A 3-fluid nozzle used for sterilizing an inner surface of a container, comprising a mixing section and a hot air mixing section, said mixing section comprising: a. a hydrogen peroxide supply nozzle at an upstream portion of the mixing section for supplying hydrogen peroxide aqueous solution to the mixing section, said hydrogen peroxide supply nozzle comprising an opening and closing valve that opens and closes a channel of hydrogen peroxide aqueous solution that is supplied to the mixing section, b. an air-at-the-normal-temperature supply nozzle at an intermediate portion of the mixing section for supplying air at the normal temperature to the mixing section, and c. an outlet at a downstream portion of the mixing section for injecting the mixture of the hydrogen peroxide aqueous solution and the air-at-the-normal-temperature into an upstream portion of a hot air mixing section; and said hot air mixing section comprising: a. a hot air supply nozzle that is provided on an intermediate portion of the hot air mixing section for supplying hot air to the hot air mixing section, and b. an outlet at a downstream portion of the hot air mixing section, wherein the hydrogen peroxide aqueous solution, the air at the normal temperature and the hot air are simultaneously injected into the container from the hot air mixing section, thereby immediately gasifying the hydrogen peroxide aqueous solution.
