Embodiment Construction

[0024] An electron beam sterilization device according to an embodiment of the present invention will be described below with reference to the drawings. In short, the electron beam sterilization equipment is equipment that sterilizes containers by irradiation with electron beams while transporting containers. In addition, the following as figure 1 As shown, the preform P is described as an example of the container. The preform P is a raw material before being formed into a plastic bottle B by blow molding, and is in the shape of a test tube (U-shaped in longitudinal section with an open upper end u).

[0025] Such as figure 2 As shown, the electron beam sterilization equipment generally has five chambers. Starting from the upstream side of the path of the conveyed preforms P, these five chambers are in order: a supply chamber 1 in which the preforms P are supplied from the outside; A surface sterilization chamber 4; an inner surface sterilization chamber 5 for sterilizing...

Abstract

Electron beam sterilisation equipment comprising: an inner surface sterilisation chamber (5) in which an inner surface electron beam irradiation device is disposed; and a shield chamber (6) which receives preformed bodies (P) from the inner surface sterilisation chamber (5) and shields X-rays generated by irradiation with an electron beam. The shield chamber (6) has: an upstream side opening (62) which receives the preformed bodies (P); and a downstream side opening (63) which transfers the preformed bodies (P). The shield chamber (6) is provided with: gripping tools (74) which grip the preformed bodies (P); an aseptic revolving table (71) which conveys the gripped preformed bodies (P) on a circular path; and shield walls (81) which shield the X-rays and are not in contact with the aseptic revolving table (71). The shield walls (81) face the upstream side opening (62) [or the downstream side opening (63)] and have a larger surface area than the upstream side opening (62) [or the downstream side opening (63)].

Description

technical field [0001] The present invention relates to electron beam sterilizing equipment for sterilizing, for example, containers for food and beverages and pharmaceuticals by irradiation with electron beams. Background technique [0002] For companies dealing with containers for food and beverages, if food poisoning incidents occur due to insufficient sterilization of the containers, their credibility in society will be seriously damaged. Therefore, in developed countries where safety of food and drink is emphasized, containers for food and drink need to be strictly sterilized. [0003] Currently, as a device for strictly sterilizing a container, a device for irradiating the container with electron beams is used. Although such an apparatus can strictly sterilize the container, it generates X-rays, which are biologically dangerous radiation, by irradiating the container with electron beams. Therefore, a configuration has been proposed in which X-rays are sufficiently sh...
