System for protecting a container treatment device by means of an electron beam

摘要

A treatment device for sterilizing containers by an electron beam includes a carousel that comprises a rotary holding plate supporting a plurality of treatment stations, each station including a sterilization device comprising an electron beam emitter, and a holding device for holding a container under the emitter. The treatment device includes a protection system for stopping the rays emitted by the emitters, the protection system comprises an annular segment-shaped, open stationary channel that is mounted in a stationary manner under the holding plate and forms, with the latter, a protective chamber in which the holding device supporting the containers moves, the channel having an open upstream end, for the inlet of the containers to be treated into the protective chamber, and an open downstream end, for the outlet of the treated containers from the chamber.

1. Treatment device for sterilizing containers by an electron beam, comprising:
a carousel comprising a rotary holding plate, supporting a plurality of treatment stations arranged with regular angular spacing, each said treatment station comprising sterilization means which include an electron beam emitter and holding means for holding a container under said emitter, said emitter being able to emit an electron beam passing through an upper opening of a container supported by said holding means in order to sterilize said container, a protection system for stopping rays emitted by the emitters, said protection system comprising a protective chamber formed by an open stationary channel mounted under said rotary holding plate; said open stationary channel configured in the form of a ring-shaped segment mounted in a stationary manner under said rotary holding plate, said open stationary channel having a transversal section with at least one of a U and a V shape said open stationary channel having an open upstream end configured as an inlet for the containers, said open stationary channel having an open downstream end configured as an outlet for the containers.
