1. Patented soft-bristled brush roller + variable frequency water flow control, dynamic adjustment of cleaning pressure, ensuring that eggshells have no hidden cracks (breakage rate ≤0.1%, industry average 0.3%). 2. The closed-loop water circulation system saves water by over 30%, meeting environmental protection requirements. 3. The combined sterilization of ozone water and ultraviolet light has a Salmonella killing rate of 99.9%, which is superior to single chemical disinfection (such as sodium hypochlorite which is prone to residue). 4. Supports switching among multiple categories such as eggs, duck eggs, and quail eggs (replacement of accessories ≤30 minutes) 5. By adopting photoelectric sensors, it can be classified by weight, color and crack defects (such as blood-stained eggs and dirty eggs identification), with an accuracy rate of ≥99%, which is much higher than that of traditional mechanical classification (85%-90%).
