Egg washing system

This creation is related to egg cleaning, especially an egg cleaning system that can fully clean the shell eggs before they enter the egg breaking process.

Birds’ eggs and feces will pass through the cloaca and be excreted, so when the hen lays eggs, the eggshell will inevitably be contaminated with the feces; while the feces of chickens contain a large amount of Staphylococcus aureus, Escherichia coli and Salmonella, once the eggshell is broken, the egg yolk or egg white is easily contaminated by the excrement attached to the egg shell, and it is easy to breed the aforementioned bacteria; and the egg yolk or egg white that breeds bacteria will be eaten by people. Cause food poisoning, and make people have symptoms such as vomiting, diarrhea or abdominal pain.

In particular, the liquid eggs used in large quantities by the bakers, due to the lack of eggshell protection, make the yolk and albumen more susceptible to contamination. Therefore, the production process and equipment related to the production of liquid eggs must meet more stringent standards; In the production of liquid eggs, manufacturers usually use high-speed egg-beating equipment for production. How to avoid contamination of the liquid eggs by the excrement attached to the egg shells during egg-beating; Moreover, the Chinese government has recently actively promoted the popularity of washed eggs Therefore, how to clean shell eggs adequately and appropriately is an important issue that the relevant industry must face in the future.

In order to provide adequate and proper cleaning of the shell eggs before the egg breaking process. This creation proposes an egg washing system, which is installed in front of the egg breaking equipment and is provided with a cleaning channel with a cover conveying device along the conveying device. There are many nozzles in the washing channel that can spray water jets to clean the shell eggs.
