As a matter of fact, our company -- ZHENGZHOU FIRST INDUSTRY CO., LTD. can provide two kinds of apple sorting machines for users.

According to my knowledge of the whole fruits and vegetables industry, the commonplace apple sorting or grading machines are size classifier and weight grader. As for the question that: How to choose suitable apple sorting machine? It totally depends on your actual demands and the final effect your wanted.

Type 1: Apple Roller Size Sorting Machine

This size grading part can be used for separating different diameters of apples from different sizes of apples. Under this circumstance, screw size sorting machine is more suitable than rolling grading section, which doesn’t do harm to apples peel. 

Type 2: Apple Turntable Weight Sorting Machine

While, if you want to pack different weights of apples into final packages for exporting or selling, this new type of turntable weight sorting machine is the best choice.
