Grains, like rice, wheat, lentils, maize, etc., as well as fine seeds and other dry material can be graded according to the length by using intended cylinder. This separating machine separates the grains by the use of rotating cylinder with impressed pockets on the interior cover. The grains larger than the pockets will remain inside, while smaller ones get into the pockets and carried forward until dropped out of the pockets into the trough. Cylinder forms the main part of this indented cylinder separator. This machine is completely enclosed with a protective hood.
