APPARATUS AND METHOD FOR STERILIZING VESSEL WITH ELECTRON BEAM

摘要

PROBLEM TO BE SOLVED: To prevent electrical charging inside a resin material as well as a surface of a resin vessel 2 in sterilizing the resin vessel 2 by applying an electron beam.

SOLUTION: A bottle support means 18 is mounted on a lower end of a cylindrical rotating shaft 44 rotatably supported by a rotating wheel 12. The bottle support means 18 includes a pair of grip members 52A and 52B by which a mouth 2a of a bottle 2 is gripped. The bottle 3 rotated and conveyed while being supported by the bottle support means 18 is irradiated with the electron beam from an electron beam irradiator 16 to sterilize the bottle. A ground electrode (a member for attracting electrons) 90 is disposed to be inserted into an inside of the resin vessel 2 through the mouth 2a thereof, and the electron beam is irradiated while the ground electrode 90 is inserted into the resin vessel 2. Since extra electrons or ions, which are generated by the irradiation to the resin vessel 2 with the electron beam, flow outside, a charge amount of the resin vessel 2 is alleviated.
