High-Speed 8-Head Automatic Tuna Filling Machine SUS304 Stainless Steel PLC

The LW-FWS50-8H is a high-speed 8-head automatic shredded tuna filling machine engineered for large-scale seafood processing enterprises and export-oriented canneries requiring sustained 40 bottles per minute throughput with uncompromising filling accuracy and maximum operational uptime. This flagship filling system represents the culmination of LWT's 16 years of food machinery expertise, incorporating full SUS304 stainless steel construction with sanitary orbital welding, advanced PLC intelligent control with extensive multi-recipe storage and remote diagnostic capability, eight independent servo-driven filling heads with dynamic metering and automatic calibration, integrated photoelectric counting with real-time OEE tracking, and comprehensive predictive maintenance monitoring. Designed for continuous-duty operation in demanding wet processing environments, the LW-FWS50-8H delivers consistent ±1% volumetric accuracy from 50g to 2000g across the complete range of shredded tuna, chunk fish, and mixed seafood product formulations. For large-scale canneries processing over 10 million containers annually, this 8-head configuration provides the throughput, precision, and reliability required to maintain competitive per-unit production costs while meeting the stringent net weight compliance standards of FDA, EU, and other international regulatory jurisdictions.

The technological sophistication of the LW-FWS50-8H is evident in every subsystem. Each of the eight filling heads features independent servo motor control with closed-loop position feedback, enabling individual head calibration, performance monitoring, and automatic deviation compensation through the centralized PLC. If any single head begins to drift from its calibrated setpoint, the system automatically adjusts that head's stroke parameters while alerting the operator through the diagnostic display, maintaining production quality without line stoppage. The dynamic metering system with automatic tare calibration continuously compensates for container weight variations, product density changes between batches, and ambient temperature effects on liquid component viscosity, ensuring consistent fill weights throughout extended production campaigns without manual adjustment. The expanded recipe storage system accommodates over 50 complete product parameter sets with password-protected access levels for operators, supervisors, and maintenance personnel, preventing unauthorized parameter changes while enabling rapid, error-free product changeovers. The integrated OEE tracking module calculates availability, performance, and quality metrics in real time, displaying production dashboards on the touchscreen and exporting data via USB or optional Ethernet connection for integration with factory MES and ERP systems. Remote diagnostic capability allows LWT support engineers to securely connect to the PLC for troubleshooting, parameter optimization, and software updates, dramatically reducing response time for technical issues at overseas production facilities.
