Nowadays, more and more egg-washing machines are automated, and highly intelligent, fully automatic models are already equipped with water temperature monitoring functions. As winter brings lower ambient and water temperatures, which can affect cleaning quality, what is the appropriate water temperature for egg-washing machines during the winter months?
The temperature used in fully automatic egg-washing machines is generally at least 11 degrees higher than that of the raw eggs themselves, and typically does not exceed 49 degrees.

Consequently, in winter, the temperature of the egg-washing machine should be maintained at around 10 degrees Celsius below 50 degrees Celsius. Egg-washing machine Water temperature too low: If the water temperature is below 10 degrees Celsius, parts of the eggshell will contract, creating a vacuum pressure difference between the inside and outside, which makes it easier for bacteria on the shell to penetrate the egg cell. This also affects the cleaning effectiveness of the egg-washing machine.
Water temperature too high: If eggs are left in hot water above 50°C for an extended period, they will be ‘cooked’. You can clean the surface of the eggs with washing-up liquid and allow them to dry naturally.
