Seafood Canning Line

Designed for canned fish products, the seafood canning production line is suitable for tuna, sardines, mackerel, tilapia, ribbonfish, anchovies, and other fish raw materials. It can produce canned fish in oil, tomato sauce, brine, seasoning sauce, and ready-to-eat flavors, with packaging options including tin cans and glass jars.

The production line uses a PLC intelligent control system and integrates washing, scaling, head and tail cutting, pre-cooking, filling, seaming, and sterilization into one continuous process. It is especially suitable for medium and large seafood processing companies, helping improve production efficiency, reduce raw material loss and labor costs, and meet export and factory audit requirements.

  • Capacity: 20–100 cans/min, customizable according to production requirements
  • Operation mode: Fully automatic, with manual emergency operation
