Sterilization apparatus for sterilizing packaging containers, the sterilization apparatus comprising a first carousel for supporting a plurality of sterilization devices, the sterilization devices being adapted to sterilize an interior of the packaging containers by electron beam irradiation, and a transport system for transporting the packaging containers, the transport system comprising a second carousel coaxial with the first carousel, wherein the first carousel comprises a first rotatable shaft and the second carousel comprises a separate second rotatable shaft coaxial with the first rotatable shaft.

Sterilization machine and method for sterilizing packaging containers

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.

Method and device for sterilizing packaging material

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.

Device and method for sterilization of packaging containers

The invention relates to a sterilization device for sterilizing packaging containers with electron beams in a filling machine. The sterilization device comprises at least one first electron beam emitter adapted for sterilization of at least the interior of the packaging container and at least one electron beam emitter adapted for sterilization of at least the exterior of the packaging container. The invention further comprises a method for sterilizing packaging containers.

Device and method for sterlizing packaging containers by electron beam

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.

Device and method for sterilizing a packaging container

The invention relates to a method for sterilizing packaging material, comprising 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.

A unit () for separating opening devices () supplied in the form of a row () and to be applied singly to respective sealed packages () of pourable food products, the unit having a separating assembly (), in turn having a first and a second jaw () movable along a path (P) and defining a seat (), which is movable between an open configuration, in which it receives an opening device () from the row () at a first station (I) along the path (P), and a closed configuration, in which it moves the opening device () singly along the path (P) to detach it from the rest of the row (); the unit () also has elastic means () for loading at least the first jaw () towards the second jaw (); a conveyor () for conveying the opening devices (), and which is separate from the separating assembly (); and at least a first cam () activated by the conveyor () and cooperating cyclically with a cam follower (), integral with the first jaw (), to move the first jaw (), in opposition to the elastic means (), away from the second jaw () and move the seat () into the open configuration.

Separating unit for separating opening devices to be applied singly to respective packages of pourable food products

A method of separating opening devices supplied jointly in the form of a sheet and applied individually to respective packages of pourable food products involves feeding the sheet, which has a number of parallel rows of opening devices integral with one another, to a first station where a first row is detached from the rest of the sheet. The first row is fed to a second station where it is divided into individual opening devices, and a following second row of the sheet is fed to the first station as the preceding first row is being fed to the second station and/or is being at least partly divided.
