Abrégé

A sterilizing device evenly irradiating an entire surface of a food with electron beam to provide a sterilizing effect based on the electron beam to the entire surface is provided. The sterilizing device includes: an electron-beam irradiator unit 10 configured to irradiate a process-target object (such as a raw egg) 40 with electron beam EB; a placement stage 22 for the process-target object 40; and a slit SL arranged between the process-target object 40 and the electron-beam irradiator unit 10, the slit unit SL includes a plurality of openings, and is arranged to be upper than a high portion of the process-target object 40. In this manner, since the process-target object 40 is irradiated with the electron beam EB through the slit SL, its entire surface can be more evenly irradiated with the electron beam, and a sterilizing effect based on the electron beam can be provided to the entire surface. The influence of the bremsstrahlung X ray caused by the irradiation with the electron beam on the inside contents of the process-target object 40 can be made small, and a dose of the X ray with which the inside contents (that is the portion to be the eatable part) of the process-target object 40 is irradiated can be made small so as to meet a criterion value regulated in a law or others.

Abrégé

Provided is a sterilization device that irradiates a food with an electron beam more uniformly on the entire surface of the food, and that imparts a sterilizing effect by the electron beam on the entire surface. The present invention includes an electron beam generation unit 10 that irradiates an object to be treated (for example, a raw egg) 40 with an electron beam EB, a mounting stand 22 for the object to be treated 40, and a slit SL disposed between the object to be treated 40 and the electron beam generation unit 10. The slit SL includes a plurality of openings, and is provided above a high portion of the object to be treated 40. Thus, the object to be treated 40 is irradiated with the electron beam EB through the slit SL and, as a result, the entire surface can be irradiated more uniformly with the electron beam, and a sterilizing effect of the electron beam can be imparted on the entire surface. Additionally, the effects of braking X-rays, generated due to the irradiation with the electron beam, on the interior of the object to be treated 40 can be reduced, and the dose of X-rays that the interior (edible portion) of the object to be treated 40 is irradiated with can be kept low so as to satisfy standards stipulated by legal regulations and the like.
