Canned Tuna Production Line

The PLC-controlled canned tuna production line is designed for industrial continuous production, with line accuracy, operating stability, and food safety compliance matched to the needs of medium and large processing plants.

The production line can reduce manual operation across the process, lower production costs, and support efficient, compliant tuna canning. It is suitable for canned tuna chunks, tuna flakes, tuna in oil, tuna in brine, and other deep-processed tuna products.

  • Control system: PLC intelligent control, with operation interface for coordinating the whole production line
  • Capacity: 1–5 tons/h, adjustable according to factory requirements with unified line operation
  • Operation mode: Fully automatic, with manual emergency operation; each process can be controlled separately
  • Applicable products: Full-process canning for tuna and other seafood products
Features
  • Industrial-grade PLC control coordinates the operation of the whole production line, keeping each step accurate and stable while reducing uneven line operation and process disconnection.
  • The production line is compatible with common can types, and parameters can be switched with one touch to support different canned tuna specifications.
  • Food-contact parts are made of food-grade 304 stainless steel, covering filling, seaming, and other direct-contact processes to meet food processing hygiene requirements.
  • The complete production line can replace multiple manual workstations, including filling, seaming, sorting, and other process steps, helping reduce labor and management costs.
