Standard 6-Head Automatic Tuna Filling Machine SUS304 Stainless Steel PLC Control 30 Bottles/Min

The LW-FWS50-6H is a standard 6-head automatic shredded tuna filling machine engineered for mid-size seafood canning enterprises requiring reliable 30 bottles per minute throughput with industrial-grade precision and multi-product flexibility. Constructed entirely from SUS304 food-grade stainless steel with sanitary welding and polished surface finish, this filling system represents the optimal balance of production capacity, filling accuracy, and operational simplicity for established seafood processors scaling from manual or semi-automatic operations. The PLC intelligent control system with multi-recipe touchscreen storage manages all critical filling parameters across multiple product formulations, enabling rapid changeovers between shredded tuna in oil, chunk tuna in brine, salmon flakes in sauce, and mixed seafood products without mechanical adjustments or recalibration procedures. At the core of the LW-FWS50-6H, six independent servo-driven filling heads with dynamic metering technology deliver ±1% volumetric accuracy with automatic tare calibration, ensuring consistent net weight compliance across the full 50-5000ml filling range while minimizing costly product overfill that directly impacts per-unit profitability in competitive canned seafood markets.

The LW-FWS50-6H builds upon the proven LW-FWS50 platform with significant enhancements for mid-scale production environments. The expanded 6-head configuration increases throughput to 30 bottles per minute while maintaining the same compact operational footprint, enabling production facilities to double output without doubling floor space requirements. The multi-recipe touchscreen system stores complete parameter sets for up to 30 different product formulations, including filling volume, head speed profiles, drip cutoff timing, and container height offsets. This capability is particularly valuable for contract canning operations producing multiple brand specifications from a single filling line, where recipe-driven changeovers eliminate setup errors and reduce transition time between production campaigns. The integrated photoelectric counting system has been upgraded with cumulative production tracking and shift-based reporting, providing production managers with real-time OEE data and batch traceability without dedicated SCADA infrastructure. The directional feeding system includes an enhanced anti-bridging agitator in the stainless steel hopper that actively prevents fibrous tuna meat from compacting and interrupting product flow, a common challenge when processing high-protein shredded fish products that tend to mat and interlock during extended production runs. The fault display system has been expanded with detailed diagnostic codes, maintenance interval reminders based on actual cycle counts, and consumable part life tracking for predictive replacement of wearing components including filling nozzle seals, pneumatic cylinder piston rings, and metering chamber O-rings.

• 6-Head High-Throughput Configuration: Six independent servo-driven filling heads delivering 30 bottles per minute sustained throughput, doubling the capacity of 4-head configurations while maintaining the same compact operational footprint. Each head independently calibrated with automatic deviation monitoring across production runs.
• Multi-Recipe PLC with 30-Product Storage: Advanced touchscreen interface storing complete parameter sets for up to 30 product formulations. One-touch recipe changeover eliminates manual recalibration between different tuna, salmon, and mixed seafood products, reducing changeover time to under 5 minutes with two operators.
• Dynamic Metering with Auto-Tare Calibration: Enhanced dynamic metering system with automatic tare weight compensation adjusts fill volume based on real-time container tare weight variation, a critical feature for glass jar applications where individual container weights can vary by several grams and affect final net weight compliance.
• Anti-Bridging Agitator System: Integrated hopper agitator with variable-speed drive actively prevents fibrous tuna meat from compacting, matting, and bridging during extended production runs. This ensures consistent product flow to all six filling heads without operator intervention to manually clear blockages.
• Enhanced Production Tracking and Diagnostics: Upgraded photoelectric counting with shift-based production reports and cumulative batch traceability. Expanded fault diagnostics with detailed error codes, maintenance interval alerts based on actual machine cycles, and consumable part life tracking for predictive replacement scheduling.
• IP55+ Rated for Continuous Wet Environment Duty: Fully sealed electrical enclosure with stainless steel conduit and cable glands, IP55+ rated control panel with positive-pressure ventilation, and marine-grade connector interfaces ensure reliable 24/7 operation in seafood processing environments with frequent washdown procedures and high ambient humidity.

The LW-FWS50-6H is engineered for mid-size seafood processing enterprises producing branded and private-label canned tuna and aquatic products for domestic supermarket chains and regional export markets. With a sustained throughput of 30 bottles per minute equivalent to approximately 1,800 containers per hour, this filling machine supports annual production volumes in the 3-5 million container range on single-shift operation. Primary applications include premium solid-pack tuna in olive oil for Mediterranean and European retail markets, chunk-style tuna in vegetable oil for mainstream domestic distribution, shredded tuna with spiced sauces for Southeast Asian and Middle Eastern consumer segments, salmon flakes in brine for health-conscious Northern European markets, and mixed seafood medleys combining tuna, mackerel, and vegetables for ready-to-eat meal product categories. The multi-recipe storage capability enables contract canning facilities to efficiently manage production campaigns for multiple brand clients, with complete parameter segregation preventing cross-contamination of filling specifications between different customer formulations. The machine accommodates the full range of seafood container formats including standard 185g tuna cans, 95g snack-size tins, 400g family-size cans, and 200-500ml glass jars for premium product positioning, with container format changeovers achievable in under 10 minutes using the stored recipe parameters and quick-release guide rail adjustments.

Each LW-FWS50-6H filling machine undergoes complete factory assembly, calibration with certified test weights, and a minimum 8-hour continuous production trial using actual shredded tuna product across multiple container formats at the LWT 20,000 m² manufacturing facility. The machine is disassembled into logical modules with match-marked connections for simplified site reassembly. All components receive VCI anti-corrosion treatment, multi-layer PE film wrapping with desiccant packs, and crating in heavy-duty fumigation-free plywood cases with ISPM-15 certification for international ocean freight. The PLC control panel and touchscreen HMI are shipped as a sealed module in a dedicated shock-resistant case. A comprehensive 12-month spare parts kit accompanies each shipment, containing filling nozzle seals, metering chamber O-rings, pneumatic cylinder seal kits, solenoid valve rebuild sets, conveyor belt segments, sensor calibration references, and touchscreen protective overlays. LWT's after-sales program includes remote video-guided installation, optional on-site commissioning by factory-trained field engineers, structured operator training covering filling parameter optimization and product changeover procedures, preventive maintenance certification for in-house maintenance technicians, 1-year comprehensive machine warranty, 3-year coverage on core components including PLC, servo motors, and filling head assemblies, and timely global supply of genuine LWT wearing parts and consumables through the company's international spare parts distribution network serving customers in over 80 countries.
