Abstract
A beam handling system that switches between two beam distribution systems (irradiation areas). When the first product has passed the beam, the second product starts to be irradiated in the second beam. This may be the same beam but directed in a different direction, or two separate beams, and the switching of direction is synchronized to occur as one product irradiation is completed and the second comes into position.
Claims18
A method for irradiating products with electron beams from at least one electron beam delivery device, each of said products being contained in a container moving along a path past said at least one electron beam delivery device, comprising the steps of:
- controlling said at least one electron beam delivery device to switch beam delivery positions on said path, thereby irradiating at least two different locations on said path, and
- synchronizing the switching of the at least one beam delivery device between different beam delivery positions with positions and speeds at which products are conveyed along the path.
A system for irradiating products with electron beams from at least one electron beam delivery device, each of said products being contained in a container moving along a path past said at least one electron beam delivery device, comprising:
- means for controlling said at least one electron beam delivery device to switch beam delivery positions on said path, thereby irradiating at least two different locations on said path, and
- means for synchronizing the switching of the at least one beam delivery device between different beam delivery positions with positions and speeds at which products are conveyed along the path.
