OThe Length Grader is used to separate the whole grains from the broken or shorter ones according to the variance in length between the whole grain and the-broken ones. When in combination with a traditional rice grading sieve, it is efficient for resulting in the whole grains without any brokens or broken grains without any whole ones.

OA multiple indented cylinder combination is adopted in structure in this Length Grader, which is characteris-tic of compact design, light body, easy assembly/disas-sembly and operation.
