A disinfectant vaporizing apparatus for dropwise flowing a disinfectant liquid on a heating unit so as to provide a uniform disinfection gas on a surface of a material to be sterilized, characterized in that at least one supply port for supplying heated carrier gas at a high temperature is provided in a vaporization chamber for the disinfectant liquid. A vaporization part is provided with a plurality of cavities on an upper surface thereof and at least one dropping nozzle is provided above each cavity, wherein the disinfection gas carried by the heated carrier gas is applied on a surface of a material to be sterilized through a droplet splash removing apparatus. The droplet splash removing apparatus has a series of vertically, spaced-apart shield plates with staggered holes therein through which the vaporized disinfectant and carrier gas pass and entrained droplets of disinfectant liquid are removed.

Disinfectant vaporizing apparatus

A rotatable partition is provided to establish a sealing relationship between each pair of successive processes in a germ-free filling/packaging system or between a said processes and the outer air and a hollow cylinder containing therein this rotatable partition is provided with an inlet through which germ-free gas flows in and an outlet through which germ-free gas flows out. Floor(s) of a germicide mist fixing station and/or a germicide removing station, and/or conveyor arms is (are) provided heater elements.

Method for container conveyance in germ-free filling/packaging system

An outer container is detachable mounted on a neck of an inner container having its interior previously sterilized and sealed with a portion of the inner container underlying the neck being sealed. Such container assembly of double structure is sterilized and dried, then transferred into a germ-free filling chamber isolated from the atmosphere here the top of the inner container is cut off, then the inner container is filled with food or drink and the cut off portion is sealed again. Finally the outer container is separated from the inner container outside the germ-free filling chamber.

Container and method for germ-free packaging

A hydrogen peroxide gas maintained at a temperature which is higher than its condensing temperature at the least is admitted to a surface of an object to be sterilized, the hydrogen peroxide gas is condensed on the surface of the object maintained at a temperature below the condensing temperature to sterilize the object, and thereafter the hydrogen peroxide is removed by hot air.
