Patent number: 10053252Abstract: 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.Type: GrantFiled: August 21, 2017Date of Patent: August 21, 2018Assignee: TETRA LAVAL HOLDINGS & FINANCE S.A.Inventors: Roger Lindgren, Håkan Mellbin, Jonas Dickner, Fredrik Hansen

Patent number: 9850014Abstract: 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.
