Poultry egg sterilization method

Abstract

The invention discloses a poultry egg sterilization method, comprising: conveying in a predetermined direction, poultry eggs to be sterilized through a conveying mechanism, while keeping the poultry eggs rotating in a predetermined direction through the conveying mechanism; producing low-energy electron beams of predetermined energy by an electron beam generating mechanism arranged on the conveying mechanism so as to irradiate with the low-energy electron beams, shells of the poultry eggs passed on the conveying mechanism, so that microbes attaching to the surfaces of the shells of the poultry eggs and microbes hiding in micropores of the shells of the poultry eggs are killed. According to the poultry egg sterilization method, low-energy electron beams are used to irradiate the surfaces of the poultry eggs to kill the microbes attaching to the surfaces, the electron beams partially enter the micropores of the shells to kill the microbes hiding in the micropores and close to inner membranes at the tail ends of the micropores, the killing rate may reach 99.9% and above, and reliable aseptic poultry eggs are acquired.

Description

technical field [0001] The present invention relates to a sterilization method for use in the context of food processing. More specifically, the present invention relates to a method of sterilization of poultry eggs for use in the case of poultry egg or poultry egg product processing. Background technique [0002] A large number of microorganisms, especially a large number of pathogenic bacteria, adhere to the surface of poultry egg shells, which are harmful to humans. As the storage time prolongs, microorganisms will slowly enter the eggshell through the micropores on the eggshell, causing the egg to deteriorate. In addition to being sold as a whole, it will also be made into egg products, such as liquid eggs (egg white liquid, egg yolk liquid, whole egg liquid) and egg powder, to meet people's eating needs, but in order to reduce the cost of direct sterilization of egg products to consumers Therefore, the current operation is to control microorganisms at the source of eg...

Problems solved by technology

[0003] At present, there are many ways to sterilize poultry eggs. For details, see "Research on Key Technologies of Clean Egg Production Process". The radiation method mentioned in it usually refers to high-penetrating gamma rays or high-energy (1MeV~10MeV) Electron beams, these rays have strong penetrating ability, can kill all microorganisms inside and outside poultry eggs, and can even penetrate packaging materials for sterilization, which is convenient to use. However, while sterilization, the contents are also irradiated, and there will be Changes, and even "irradiation odor" will appear, which will affect the quality of food. Therefore, most of the current methods are relatively advanced ultraviolet sterilization. However, due to the weak penetration of ultraviolet rays, the sterilization is not complete, and even if the irradiation time is prolonged, the surface cannot be completely killed. In addition, the micropores on the eggshell cannot enter the ultraviolet rays, and cannot kill the microorganisms inside the micropores, and cannot be completely sterile

Other sterilization methods have obvious defects, and it is urgent to develop more advanced sterilization technology
