From Raw Fish to Sealed, Sterilized Cans – End-to-End Automation for Safe, High-Quality Tuna Products

In today’s competitive seafood market, safety, consistency, and efficiency are non-negotiable. Our Fully Automatic Canned Tuna Processing Production Line delivers a complete, turnkey solution that transforms whole frozen or fresh tuna into commercial-grade canned tuna—ready for retail, export, or institutional use—with minimal human contact, zero cross-contamination, and full compliance with global food safety standards.

Designed for tuna processors, seafood exporters, and food manufacturers worldwide, this line integrates 10 core machines into one seamless workflow, enabling 24/7 high-volume production while preserving the delicate texture, flavor, and nutritional value of premium tuna.

🔍 How It Works: Step-by-Step Process Flow

The entire line follows HACCP-aligned processing logic, ensuring every can meets international safety requirements:

Thawing & Washing
→ Frozen tuna blocks are gently thawed in controlled water baths, then thoroughly rinsed to remove surface impurities.
Automatic Filleting & Deboning
→ High-precision filleting machine removes skin, bones, and dark meat with >95% yield retention.
Cooking (Steam or Water Bath)
→ Fillets are cooked uniformly to preserve moisture and protein integrity (adjustable time/temp).
Cooling & Draining
→ Rapid cooling stops overcooking; excess liquid is drained to prepare for filling.
Portion Cutting & Weighing
→ Fillets are cut into uniform chunks/flakes and precisely weighed for consistent can content.
Can Loading (Empty Can Feeding)
→ Empty cans are automatically fed, oriented, and conveyed to the filling station.
Automatic Filling
→ Tuna pieces + brine/oil/sauce are filled into cans with ±1g accuracy.
Lid Seaming (Double-Seam Closing)
→ Hermetic sealing ensures long shelf life and prevents leakage or contamination.
Retort Sterilization (High-Temperature Cooking)
→ Cans undergo precise thermal sterilization (e.g., 121°C for 60–90 mins) to eliminate pathogens.
Cooling, Drying & Labeling
→ Sterilized cans are cooled, dried, labeled, and ready for boxing or palletizing.

✅ Optional Add-ons: Metal detection, vision inspection, date coding, automatic cartoning, palletizing robot.

💬 Real Customer Impact

"Before this line, we lost 15% of tuna to inconsistent trimming and had frequent FDA holds due to sealing defects. Now, our yield is up 12%, and we’ve passed three consecutive EU audits with zero non-conformities."
— Mr. Sato, Plant Manager, Pacific Seafoods (Philippines)

"We went from 2,000 to 5,000 cans/hour with the same team. The automatic seamer alone reduced leak complaints by 98%."
— Amina Diallo, Operations Director, West Africa Canning Co. (Senegal)
