Mackerel & Herring

Fish must be processed shortly after catch

Both mackerel and herring must be processed shortly after being catched to preserve their good taste and high content of vitamins and minerals. They must be sorted, packed and frozen within a few hours to ensure the high quality and visual expression of the fish.

Equipment for fish factories

Intech supplies both complete fish lines to trawlers and fish factories on land, but also single machines and equipment. Common to the stainless process equipment is that we never compromise on product quality. We know the life on board trawlers, because we have been there ourselves, and we know all about the work processes at fish factories on land. Both places have high demands and expectations for the equipment, which constitute the fish processing line. We streamline food processing with our machines and equipment, which means you get a fast, efficient and reliable fish line that support high productivity, more ergonomic working conditions and a sublime final product.

Process equipment for processing mackerel and herring

A fish line on board a trawler or on a land-based fish factory consists of several machines, all of which help to get the fish processed accurately and gently in a quick and efficient way.

Processing of mackerel and herring consist of different steps. On fishing vessels, the catch must first be tempered after it has been pulled on board, and then the head and tail of the fish are cut off. When the fish are to be cut, it is extremely useful with a Fish Grinder with great bite force that can easily grinds any kind of fish heads and other waste. In addition to being extremely efficient, the fish grinder also has a hygienic design, which facilitates cleaning, so that any kinds of fish-remains easily can be washed away. Next, the fish must be sorted by size. It is easy to achieve an efficient sorting of fish with Style Grader, that creates a more evenly distributed layer of fish across the conveyor belt. This results in a very accurate grading of sizes. Subsequently, the fish is cleaned and filleted before being transported on to the weighing, freezing and packaging processes. In the freezing process, the fish must be frozen for increased shelf life, and so the vessels can stay longer at sea. In this step, it is possible to avoid heavy lifting and touching the fish blocks by using the Automatic Discharge System combined with a vertical freezer. In the packaging process, our One-in-All Machine is very popular, as it is a unique combination of a block knockout, box folder and block-in-box. Finally, the fish are palletized and are ready for pilotage when the trawler enters port again.
