Standard Fully Automatic Sardine Canning Production Line 60 CPM SUS304 Stainless Steel Vacuum Sealing System

The NW-SCL-60 is a standard fully automatic sardine canning production line engineered for mid-size seafood processing enterprises requiring reliable 60 cans per minute throughput with industrial-grade automation and consistent product quality. Constructed entirely from SUS304 food-grade stainless steel, this comprehensive turnkey solution transforms fresh sardines into premium shelf-stable canned seafood products through an optimized sequence of manual fish loading and weighing, automated exhaust removal, precision brine and oil filling, vacuum can seaming, post-seal can washing, high-temperature retort sterilization, and high-resolution inkjet batch coding. The line is controlled by a centralized PLC system with an intuitive HMI touchscreen interface that provides real-time production monitoring, parameter adjustment, recipe management for multiple sardine product formulations, and fault self-diagnosis with historical alarm logging. Designed for continuous single-shift operation with the capability for extended double-shift production during peak fishing seasons, the NW-SCL-60 delivers the throughput, reliability, and product consistency required for established seafood brands competing in both domestic and international canned fish markets.

The production heart of the NW-SCL-60 is its precision liquid filling station, featuring servo-driven positive displacement pumps that independently meter oil, brine, and sauce components into each can at ±0.5% volumetric accuracy for liquid media and ±1% for paste formulations. This level of precision is critical for sardine canning, where the liquid-to-solid ratio directly impacts consumer perception of value and product quality. The filling system stores multiple recipes covering traditional olive oil pack, soybean oil pack, light brine, spiced brine, and tomato sauce variants, enabling rapid product changeovers without mechanical adjustments. The vacuum can seaming station draws a controlled vacuum on each can before mechanically interlocking the can body and lid through precision double-seam rollers, creating hermetic closures verified to maintain seal integrity throughout the product shelf life exceeding 24 months at ambient temperature. The exhaust machine upstream of the seamer removes residual air from the can headspace after filling, preventing oxidative deterioration of the sardine's delicate polyunsaturated fatty acids and ensuring that the vacuum drawn during sealing is not compromised by expanding gases during retort processing. Downstream, the automated can washing station uses recirculating hot water with food-grade detergent to remove all traces of oil, brine, and fish residue from can exteriors, presenting clean, retail-ready cans to the sterilization, coding, and packaging stages.

• Mid-Scale Production Architecture: Optimized 60 CPM throughput with balanced upstream and downstream capacities, eliminating production bottlenecks common in retrofitted or scaled-up entry-level lines. All stations designed for continuous single-shift operation with double-shift capability during peak fishing seasons without degradation in seal integrity or filling accuracy.
• Multi-Recipe PLC Automation: Centralized PLC controller with expanded recipe storage manages all critical process parameters for oil-packed, brine-packed, tomato sauce, and spiced sardine formulations. The intuitive HMI touchscreen provides one-touch recipe changeover, real-time production metrics, and diagnostic alerts with maintenance scheduling.
• Precision Liquid and Paste Filling: Independent servo-driven positive displacement pumps for oil, brine, and sauce components deliver ±0.5% accuracy for liquids and ±1% for paste formulations. Multi-recipe storage enables rapid product changeovers without mechanical adjustments, maximizing production flexibility for multi-SKU operations.
• Industrial Vacuum Can Seaming: High-speed vacuum can seamer creates hermetic double-seam closures verified to maintain seal integrity for 24+ months of ambient-temperature shelf storage. Controlled vacuum draw prevents oxidative degradation of sardine omega-3 fatty acids while ensuring can integrity during retort processing and international shipping.
• Automated Exhaust and Can Washing: Inline exhaust machine removes residual headspace air before sealing, preventing oxidative spoilage and ensuring consistent vacuum across all cans. The recirculating hot water can washer with food-grade detergent removes external residues, presenting clean, retail-quality can exteriors without manual intervention.
• Complete Traceability Integration: High-resolution inkjet coding system prints production date, batch number, expiry date, and QR-code traceability data on every can. This enables full supply chain visibility from fishing vessel landing date to retail shelf, meeting increasingly stringent traceability requirements in EU, North American, and Japanese seafood markets.

The NW-SCL-60 is engineered for mid-size seafood processing enterprises producing branded and private-label canned sardines for domestic retail chains and export markets. It handles the complete spectrum of sardine product formulations including extra virgin olive oil pack for premium Mediterranean and European markets, soybean oil pack for mainstream retail segments, light brine formulations for health-conscious consumers in North America and Northern Europe, rich tomato sauce variants for Middle Eastern and African markets, spiced and chili-marinated sardines for Southeast Asian and Latin American consumer preferences, and smoked sardine fillets in oil for gourmet specialty retail channels. The line accommodates multiple can formats including the international standard 125g oval and round sardine tins, 200g tall cans for family-size portions, and glass jar formats for premium product positioning. Additional applications include co-packing of complementary canned fish products such as mackerel fillets, herring in sauce, and tuna chunks with format changeovers requiring under 30 minutes. The multi-recipe PLC system enables contract canning facilities to manage production campaigns for multiple brand clients with full segregation of recipe parameters, production records, and traceability data per campaign.

The NW-SCL-60 production line is shipped in modular sections with each major station pre-assembled, tested with actual sardine product, and match-marked at the NIWI factory before careful disassembly. All modules are treated with marine-grade VCI anti-corrosion protection, wrapped in multi-layer PE film with desiccant packs, and crated in heavy-duty fumigation-free plywood cases with ISPM-15 certification for international ocean freight. The PLC control panel is shipped as a sealed, nitrogen-purged enclosure to prevent moisture ingress and corrosion during transit. A comprehensive 12-month spare parts kit is included with the initial shipment, containing critical wearing components such as seaming roll sets, pump seals, conveyor belt sections, pneumatic cylinder rebuild kits, retort door gaskets, and calibration reference standards. Every NW-SCL-60 undergoes a mandatory 48-hour continuous production trial with actual sardines during factory acceptance testing, witnessed by the customer or their appointed third-party inspector. NIWI provides comprehensive after-sales support including remote video-guided mechanical installation, on-site commissioning by senior field engineers (subject to regional scheduling), systematic operator training across production, sanitation, and maintenance functions, and full warranty coverage of 3 years on core components and 1 year comprehensive on all other machine elements with timely genuine spare parts supply.
