Fish Processing

The world's demand for fish products increases, and fish farms and fish processing plants are constantly increasing. Therefore, the fish processing industry faces new challenges in the treatment of waste generated by fish processing and the treatment efficiency of fish by-products. Centrifuge can be an essential tool to extract discred fish by-product, as well as high-quality fish oil from inedible fish processing residues. It can effectively compensate for the economic loss caused by processing efficiency.

ZK SEPARATION Decanters for Fish Processing

Fish processing usually involves separating fish oil, protein, and fish meal by centrifuges. Our equipment has a successful application case in the fish processing industry. It can be used to treat a large number of fish products. By heating and solidifying the fish, the fish products can be effectively separated into solid, water, and oil phases using a three-phase centrifuge. To further purify the separated oil phase, polishing can also be used Machine for processing. ZK provides a perfect solution for fish processing. Our centrifuges are made of food-grade materials, and at the same time, they are treated with wear resistance and high-temperature resistance. It provides a reliable guarantee for high-quality and efficient fish processing.
