ELECTRON BEAM STERILIZATION EQUIPMENT FOR CONTAINERS THAT USES REVOLVING TRANSPORT DEVICE

摘要

Electron beam sterilization equipment includes an outer-surface sterilization zone Z2 for sterilizing the outer surface of a container B by emitting electron beams when the container B is transported along circular paths L1 and L2; and an inner-surface sterilization zone Z3 for sterilizing the inner surface of the container B. An electron beam irradiator E1 is located near the upstream side of a 1-2 joint J1-2 of the circular paths L1 and L2 disposed in the outer-surface sterilization zone Z2, and a electron beam irradiator E2 is located near the downstream side of the joint. Thus, the electron beam irradiator E1 and the electron beam irradiator E2 are brought close to each other so as to sequentially sterilize the one half outer surfaces and the other half outer surface of the container B.

主权项

1. Electron beam sterilization equipment for containers having a plurality of revolving transport devices, the electron beam sterilization equipment comprising:
a plurality of shield chambers each containing one of the revolving transport devices forming a plurality of circular paths connected in series; an outer-surface sterilization zone for sterilizing an outer surface of the container by emitting electron beams from outside of the container when the container is transported upstream along the two circular paths; and an inner-surface sterilization zone for sterilizing an inner surface of the container by emitting electron beams from an electron beam irradiation nozzle inserted into the container when the container is transported downstream along the plurality of circular paths, wherein a first electron beam irradiator for emitting electron beams to one outer half surface of the container is located near an upstream side of a joint of two circular paths disposed in the outer-surface sterilization zone, and a second electron beam irradiator for emitting electron beams to the other outer half surface of the container is located near a downstream side of the joint, so that the first electron beam irradiator and the second electron beam irradiator are located close to each other.
