When combined with the Marelec Portio intelligent portioning system, the Classic Grader creates a turnkey solution for processors who want to accurately portion a high volume of product with minimal waste. Whole primals can be weighed and graded into different weight categories. After grading, portions can be transported directly to packaging machines or combined into a fixed-weight pack. Our brochure provides an in-depth look at all available options.

A major benefit of the Classic Grader is its modular design which allows for multiple customization options. Processors can choose from multiple infeed options, labeling as well as outfeed options, such as trays, batching bins, or belts for further processing. This type of flexibility makes the classic grader an ideal solution for whole primal portions, whole bird and poultry parts (including fillets, tenders, and legs) as well as batching of strips and dices after portioning.
