ELECTRON BEAM STERILIZATION DEVICE AND STERILE FILLING EQUIPMENT

摘要

A circular sterilization path (CD) is divided into a front sterilization path (Pd) having a preform sterilization section formed and a rear sterilization path (Bd) having a molded-container sterilization section formed. A single electron beam sterilization device simultaneously sterilizes a preform (P) and a molded container (B), achieving effective sterilization and a size reduction of equipment.

主权项

1. An electron beam sterilization device capable of simultaneously sterilizing a molded container and a preform of the molded container,
the electron beam sterilization device comprising: electron beam irradiation nozzles that are protruded at regular intervals and are moved along an endless sterilization path; container holders that are moved along the sterilization path so to hold the molded container and the preform; and a nozzle inserting/removing device that moves one of the container holder and the electron beam irradiation nozzle to the other so as to insert and remove the electron beam irradiation nozzle into and from the molded container and the preform, wherein the sterilization path partially serves as a front sterilization path where a container carrier device holds and transports the preform while the other part of the transport path serves as a rear sterilization path where the container carrier device holds and transports the molded container, the front sterilization path has a preform sterilization section where the nozzle inserting/removing device inserts a distal end of the electron beam irradiation nozzle into the preform from an opening portion and internally sterilizes the preform while the rear sterilization path has a molded-container sterilization section where the nozzle inserting/removing device inserts the distal end of the electron beam irradiation nozzle into the molded container from the opening portion and internally sterilizes the molded container.
