Product overview

Marelec’s Marine Grader was designed for whole fish or fillets, fresh, frozen, or vacuum-packed fish. Its graders can sort different sizes into fixed-weight trays or bulk packs based on your specifications. A major benefit of the Marine 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. Our brochure provides an in-depth look at all available options.

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.
