First Industry designs and manufactures roller grader that sort plums with gentleness, because plums are delicate fruits and bruise easily. In view of this, our plum grading machines are carefully designed to avoid any damage that might fall off during the grading and sorting process.

Plums are classified according to parameters such as diameter or weight. These parameters can be used individually or in combination to achieve a more specific grading. 

Plum sorter has many advantages, such as the operation is very convenient, only need to artificially pour the plums in the feeding part on the line; The elevator then automatically transfers the plums to the grader section. The size of plums is sorted by gradually increasing the gap between rollers. Plum sizing machine are designed to prevent damage to all areas of contact with plums to minimize damage to plums during sorting.

Last year First Industry sold a plum grading machine in Poland. The customer said that the plum sorting grading machine is very practical and the sorting effect is very good.
