Roller classifier

The drum rotates under the drive of the drive motor, because the size of holes in different areas of the drum varies. Fruit and vegetable raw materials evenly enter the drum through the conveyor, with the help of the rotation of the drum, the material constantly turns over. Because of the inclination of the drum, the material moves slowly from high to low in the role of gravity. At this time, materials of different diameters fall into the hopper from different apertures on the drum. The size of the material is graded in order to achieve the purpose of fruit and vegetable grading. The utility model has the advantages of novel structure, energy saving, high efficiency, high production efficiency, no damage to fruits and vegetables, wide application range, etc.
