Plum is a kind of nucleated fruit, so since we want to grade, we should choose a grading equipment with good grading effect but no damage to the fruit. The choice of fruit grader can choose roller grader, roller grader, stainless steel round fruit grader, mesh belt Fruit Sorter and so on, and the use effect is very good.

Today, we will first introduce the principle of plum roller classifier. The roller classifier is mainly composed of frame, drive motor, grading hopper, drive device cover, roller and other parts. The roller is its main structure, which is placed at 3 ° to 5 ° with the horizontal. The roller rotates under the drive of drive motor, because the size of holes in different areas of the roller is different. After the fruit and vegetable materials enter the drum evenly through the conveyor, the materials are continuously turned over by the rolling of the drum. Because of the skewness of the drum, the materials move slowly from high to low under the action of gravity. At this moment, the materials with different diameters fall into the hopper from different holes on the drum. The size of the material is graded in turn, and then the intention of fruit and vegetable grading is reached. The device can plan multi-level classification according to user's requirements.
