Abstract:
Provided is a sterilization device that irradiates a food having a shell or an outer skin that cover an edible portion with an electron beam more uniformly on the entire surface thereof and imparts a sterilizing effect by the electron beam on the entire surface. A sterilization device for sterilizing a food (target object 40) having an edible portion and a surface portion covering the edible portion by irradiating with an electron beam, the sterilization device comprising an electron beam generating unit 10 for irradiating the food with an electron beam and a conveying unit 21 which conveys the food while rotating so that the food may pass through an irradiation area of the electron beam from an electron beam irradiation unit. The electron beam generating unit has a chamber, a filament, and a window, and electrons emitted as a result of passing an electric current through the filament are accelerated by an accelerating voltage and pass through a foil provided in the window, thereby enabling irradiation with the electron beam. In addition, the conveying unit has a plurality of pivotally supported rollers, and the food is conveyed while rotating in the rotation direction of the rollers.
