During the operation of an egg-washing machine, issues with the eggs themselves or the commissioning of the equipment will inevitably result in egg breakage. Broken eggs not only disrupt the normal operation of the machine and contaminate the washing tank, but also directly increase the cost of egg washing. So, how can the breakage rate of the egg-washing machine be reduced?
I. Optimising the egg-washing process
A well-designed egg-washing process can effectively reduce the damage rate. For example, prior to washing, eggs can be weighed individually using a mechanical scale, with eggs of different weights directed to separate zones. Operators can then place the eggs onto egg trays. Furthermore, ensuring eggs are of uniform size can effectively prevent damage to washed eggs. II. Appropriate conveyance methods
Eggs are susceptible to impact, but are safer when submerged in water. If an automatic egg-washing machine can operate with the eggs submerged, this effectively prevents eggs from colliding with one another, thereby reducing the likelihood of damage.

III. Pay Attention to Egg Types When Purchasing
Many chicken and duck eggs are not suitable for the washing process. There are numerous causes of damage to these eggs, as they may already have been damaged by other factors prior to washing; this necessitates paying close attention to quality when purchasing eggs.
The reason for washing eggs is that they are laid through the cloaca of laying hens; the surface of the cloaca is colonised by intestinal microorganisms, and in contaminated environments, the eggs can become infected with large numbers of pathogens. Sampling surveys have shown that a small number of eggs carry Salmonella on their surfaces, whilst a large number of eggs contain E. coli levels that severely exceed safety limits. Microorganisms and pathogens on the surface of eggs can enter the egg through the numerous pores in the shell and multiply rapidly, severely affecting egg quality and posing a risk to consumers. The method to prevent egg contamination is to wash and disinfect the eggs promptly after production to kill harmful bacteria. This removes contaminants from livestock and poultry manure and eliminates the inevitable presence of pathogens and harmful substances arising during the poultry production process.
