AI Technical Summary
Existing methods for sterilizing food surfaces, such as hen's eggs, face challenges with uneven electron beam irradiation, leading to insufficient sterilization of the inside and increased radiation dose due to bremsstrahlung X-rays, especially when dirt is present on the surface.
A sterilizing device and method that uses a rotating delivery system with an electron-beam irradiator, ensuring even surface irradiation of food items with electron beams while minimizing bremsstrahlung X-ray exposure by adjusting the angle and intensity of the electron beam.
Achieves uniform surface sterilization of food items with reduced internal radiation dose, meeting regulatory standards by evenly distributing electron beam exposure and minimizing bremsstrahlung X-ray impact.
