Description

Technical Field

[0001] The invention relates to the technical field of salted duck egg sterilization, and in particular to intelligent salted duck egg sterilization equipment and a sterilization method. Background Art

[0002] The ultraviolet disinfection equipment after washing salted duck eggs is mainly composed of ultraviolet generator, reflector, transmission system, control system and safety protection device. The ultraviolet generator generates ultraviolet photons of a specific wavelength, the reflector reflects the photons to the surface of the salted duck eggs, and the transmission system ensures that the salted duck eggs are evenly irradiated. Under ultraviolet irradiation, the DNA or RNA molecular structure of the microorganisms on the surface of the salted duck eggs is destroyed and loses the ability to reproduce, thereby achieving sterilization and disinfection. The control system is responsible for adjusting the irradiation time and intensity to ensure the sterilization effect. The safety protection device protects the safety of operators and equipment. The whole equipment has a compact structure and a simple principle, and can sterilize and disinfect efficiently and evenly to ensure the hygienic safety of salted duck eggs. For example, an intelligent salted duck egg sterilization device and a sterilization method disclosed in the authorization announcement number CN118177398B include a horizontally arranged processing table, a carrier frame is fixedly arranged on the processing table, a conveyor belt for conveying duck eggs is arranged on the carrier frame, the conveyor belt is chain-type, and bearing devices for conveying duck eggs are arranged at equal intervals on the conveyor belt.

However, during the implementation of the above technical scheme, the conveyor belt will continue to drive the duck eggs to move and pass through the sterilizing light lamp. Since the salted duck eggs are located in the supporting device, the egg body part immersed in the supporting device will inevitably not be irradiated by the sterilizing light lamp, resulting in that part of the egg body is not sterilized and there is still a risk of microbial contamination. In addition, since the salted duck eggs move on the conveyor belt, they can only be exposed to ultraviolet rays for a short time, and the microorganisms deep in the eggshell surface cannot be completely killed, increasing the risk of residual microorganisms.

[0022] When the embodiment of the present application is used, the cleaned salted duck eggs are first assembled into the screw-feed self-pressing device 10.
