  • Patent number: 10053252
    Abstract: A method for sterilizing packaging material comprises an emitter that is adapted to emit charge carriers, in particular electrons, wherein the charge carriers form at least one cloud, and wherein the emitter and the packaging material are moved relative to each other so that a flow of a gaseous medium is established in between the emitter and the packaging material. The method comprises the steps of: controlling a movement profile between the emitter and the packaging material; sterilizing the flow of the medium in between the emitter and the packaging material by adjusting the movement profile so that the flow of the medium in between the emitter and the packaging material is sterilized. Also disclosed is a device for sterilizing packaging material.

  • Patent number: 9969513
    Abstract: The invention relates to a device for sterilization of the interior surface of packaging containers with electron beam, comprising an emitter provided with an electron exit window. The emitter is adapted to emit charge carriers, such as electrons, through the electron exit window, said electrons forming an electron cloud. The device comprises at least one outlet adapted to provide a flow of sterile gaseous medium adapted to maintain a local aseptic zone around at least an emitter portion including the electron exit window, thus preventing any flow of medium from outside the local aseptic zone from coming into the local aseptic zone. The invention also relates to a method.

  • Patent number: 9850014
    Abstract: The invention relates to a device for sterilization of the interior surface of packaging containers with electron beam, comprising an emitter provided with an electron exit window. The emitter is adapted to emit charge carriers, such as electrons, through the electron exit window, said electrons forming an electron cloud. The device comprises at least one outlet for conditioning at least a sterilized volume in the packaging container. The outlet is adapted to provide a flow of a sterile gaseous medium, thereby generating a first condition at least inside the sterilized volume of the packaging container. The first condition is adapted to prevent any flow of medium from outside the sterilized volume from coming into the sterilized volume without first being sterilized by the electron cloud. The invention also relates to a method.
