Fish grading machine – it is a type of equipment used in the seafood industry to sort and grade fish according to their size and quality. Therefore, these machines are designed to automate the process of sorting and grading on fish processing lines.
Normar has been operating with the fish grading and sorting machines for over 25 years, buying and overhauling used machines and then selling them to customers. Overhauling machines involves refurbishing and repairing any worn or damaged components, ensuring the machine is in good working condition before it is resold.

In industrial seafood production, grading and sorting determine yield accuracy, pricing tiers, and downstream processing stability. A modern fish grading system typically combines dynamic weighing conveyors, PLC control (often Siemens or Allen-Bradley based), and multi-lane distribution gates. Leading manufacturers such as Marel, Baader, and Uni-Food Technic have refined fish grading equipment to handle species-specific calibration for salmon, cod, and pelagic fish.
Fish grader machine classifies fish by weight ranges with high-speed load cells, while a fish sorting machine distributes product automatically into preset categories. In high-throughput plants processing 5–20 tons per hour, a seafood sorting machine ensures stable product flow before filleting or portioning. The integrated sorting and grading of fish improves traceability, supports digital batch recording, and aligns with modern HACCP and EU food safety compliance requirements.
Investment in professional fish grading equipment directly improves yield control and production planning. Automated fish grading reduces manual handling variability and ensures accurate size segmentation, which is critical for filleting lines and fixed-weight retail portions.
A calibrated fish grading system minimizes product giveaway by directing raw material to the correct processing stream. A high-capacity fish sorting machine also reduces labor costs and stabilizes throughput during peak landing periods. In modern seafood facilities, where efficiency and margin control are decisive, reliable fish sorting and grading solutions form a central part of processing optimization strategy.
When choosing a fish grading machine, there are several factors that you should consider to ensure you make the right choice for your specific needs. Here are some important factors to consider:
Determine the volume of fish you need to grade per hour or per day. Choose a machine that can handle your desired capacity efficiently without compromising the grading accuracy.
Look for a machine that provides accurate grading results. The grading accuracy will depend on the machine’s design, technology used, and the precision of its sensors or cameras. Ensure that the machine can meet your specific grading requirements.
Assess the machine’s durability and maintenance requirements. Check if the machine is constructed with high-quality materials and components. Consider the availability of spare parts and technical support in case of breakdowns or repairs.
Ensure that the equipment is capable of handling a wide range of fish species and sizes. Fish can vary significantly in terms of shape, texture, and dimensions, so it’s important to choose a machine that can accommodate these variations. Look for a machine that offers adjustable parameters or customizable grading settings to cater to different fish types.
Consider whether the machine can integrate smoothly with other processing equipment in your production line. Efficient integration allows for seamless transfer of fish between different stages of processing, such as washing, scaling, gutting, or filleting. That is why compatibility with conveyor systems, automated lines, or manual handling processes is crucial to maintaining a continuous and efficient workflow.
