How are peanuts graded?

The peanut grading machine adopts a chain wheel and chain drive push rod to make the screening body smoothly reciprocate screening. First, workers need to put peanuts into the charging barrel, the lifter then drives the peanuts into the grader. The screen will shake when the machine is running. Peanut kernels will be divided into 4-5 grades through multiple grading screens. Finally, different grades of peanut kernels will come out from different outlets.
