Fish processing machinery peeling machine

A machine for removing the skin from fish fillets. The main components are a pair of rollers of different diameters and relatively rotating knives. The tail end of the fish fillet is clamped by the rollers. When the fish skin is rolled between the large and small rollers, the knife immediately cuts the fish skin surface continuously to separate the fish meat from the skin. Some skinning machines use the freezing method to peel the skin. Refrigerant is introduced into the metal roller to make the surface temperature reach about -10℃. When the fish fillet passes through the roller, it is immediately frozen and adheres to the wall of the roller. The knife can cut the fish skin close to the surface of the fish skin. There are two types of fish skinning machine knives: reciprocating and ring belt. The latter can reduce mechanical noise. At present, herring, cod, flounder and other fish in European countries have basically achieved mechanized processing, and the products have been serialized. Since the 1960s, in order to obtain fresh raw materials, Federal Germany, Poland, the Soviet Union and other countries have installed fish processing machinery lines on trawl processing fishing boats to produce frozen fish fillets. Each ship can process 130 tons of raw materials per day. Since the 1950s, China has tried to produce yellow croaker cutting machines and fish skinning machines, and later successively produced cutting machines for other fish such as hairtail and pufferfish.
