Compact Grader


The Marelec M3 Compact Grader has been specially designed for the weighing and grading of small vulnerable products such as fish, poultry and meat. This efficient system is designed with infeed, weigher and outfeed in one simple and robust solution and the intelligent batching software can grade to size and number.


With the Marelec M3 compact grader Marelec sets the new standard for grading systems. The patented Marelec solution leads the way in this field with various batching and other outfeed possibilities, from 2 to 8 stations, combined left/right or in line and by size.

Gentle Grading

Because grading small vulnerable products at high speeds requires a gentle approach, the Compact Grader has been designed to gently pull product off the belt instead of propelling it. This reduces the risk of unnecessary product damage, rejected items or consumer complaints.
