If you have higher requirements on the capacity and quality of your egg production, ZENYER provides egg graders that function with more automation. This type of egg grader sorts through an electronic senor weighing scale and all steps are completely automatic from egg loading to tray filling with fully no human contacts and no egg collisions. Gentle operation is guaranteed on each egg. By using egg graders, the growth and spreading of bad bacteria is prevented and the cracking rate is kept at nearly 0%.
