In the meat and seafood industry, food safety is non-negotiable. Metal fragments from processing equipment (blades, grinders, slicers) pose a critical risk to consumer health and brand reputation. Additionally, the high moisture, salt, and fat content of these products creates strong “product effect” signals that can overwhelm conventional metal detectors, leading to false rejects, wasted product, and production delays.
The Fanchi-tech Conveyor Metal Detector is purpose-built to solve these challenges. Engineered specifically for meat and seafood processing lines, this robust, hygienic system delivers reliable metal contamination control, even in the most demanding conditions.
1. Advanced Detection Technology to Overcome Product Effect
Meat and seafood products—especially raw, marinated, or frozen varieties—are highly conductive, creating strong signals that can mask metal contaminants. The Fanchi-tech system solves this with:
- Dual-Frequency Adaptive Detection: Simultaneously analyzes low and high-frequency signals to suppress interference from moisture, salt, and fat. This ensures accurate identification of ferrous, non-ferrous, and stainless steel contaminants while minimizing false rejects.
- Ultra-High Sensitivity: Detects metal fragments as small as 0.8mm (ferrous), 1.2mm (non-ferrous), and 1.5mm (stainless steel), even in high-density products like frozen fish blocks or processed meat patties.
- Automatic Product Learning: The system “learns” the unique signal of each meat/seafood product, creating optimized detection profiles to ensure consistent performance across diverse SKUs.
2. Hygienic, Washdown-Ready Design
Meat and seafood facilities require equipment that withstands daily high-pressure washdowns and harsh cleaning chemicals:
- 304 Stainless Steel Construction: A fully crevice-free, smooth-finish frame prevents bacteria buildup and supports daily wet cleaning, complying with HACCP, GMP, and BRC hygiene standards.
- Food-Grade Conveyor Options: Choose between:
- White PU Belt: Ideal for fresh or frozen meat/seafood, oil-resistant and easy to clean.
- Stainless Steel Roller Conveyor: Perfect for heavy, rigid products like crated fish or bulk meat cuts, with corrosion-resistant rollers that resist moisture damage.
- IP65-Rated Electronics: Sealed control panels and components protect against water jets and dust, ensuring reliable performance in washdown environments.
3. High-Volume, Line-Friendly Operation
Designed to keep pace with fast-paced meat and seafood processing lines:
- Customizable Conveyor Speeds: Supports line speeds up to 60m/min, matching the throughput of slicing, grinding, and packaging equipment.
- Automated Rejection Systems: Choose from:
- Air Blower Rejectors: For light, packaged products like vacuum-sealed fish fillets.
- Pneumatic Push-Rods: For heavy, bulk items like meat blocks or crated seafood.
- Diverter Gates: For high-volume lines, diverting contaminated products into locked bins without halting production.
- Modular Design: The detector can be easily integrated into existing processing lines, with adjustable height and width to fit crated, bulk, or packaged products.
4. Compliance & Traceability Features
Meat and seafood processors must meet strict regulatory and retailer requirements:
- Multi-Language Touchscreen HMI: Store up to 100 product recipes, adjust detection parameters, and monitor real-time performance with English, Spanish, French, and other optional languages.
- Comprehensive Data Logging: Automatically records inspection results, reject events, and system performance, with data export via USB or Ethernet for audit trails and regulatory reporting.
- Certifications: CE, ISO9001, and ISO14001 certified, ensuring compliance with international food safety standards.
Customer Background
Nordic Seafoods, a leading Norwegian seafood processor, produces over 80 SKUs of frozen fish fillets, smoked salmon, and breaded seafood products for major European supermarket chains. The company operates three high-volume processing lines, with daily output exceeding 20 tons.
Challenge
Before adopting the Fanchi-tech Conveyor Metal Detector, Nordic Seafoods faced two critical issues:
- Unreliable Detection: Its previous metal detectors struggled with the high moisture and salt content of seafood, leading to frequent false rejects (up to 7% of production) and occasional missed contaminants.
- Compliance Risks: Retail partners threatened to terminate contracts due to inconsistent metal detection performance, which failed to meet EU food safety regulations.
Solution
Nordic Seafoods integrated four Fanchi-tech metal detectors into its processing lines. The systems were configured with stainless steel roller conveyors for bulk frozen fish blocks and PU belt conveyors for packaged fillets, calibrated to detect metal fragments as small as 1.0mm.
Results
- Zero Contamination Incidents: The detectors eliminated the risk of metal fragments reaching consumers, resolving all compliance issues with retail partners.
- 95% Reduction in False Rejects: The dual-frequency technology minimized interference from product effect, reducing false reject rates from 7% to below 0.3% and saving the company over €150,000 annually in product waste.
- Improved Line Efficiency: Automated rejection systems eliminated manual sorting, freeing up 6 full-time operators and reducing production downtime.
- Full Retailer Compliance: The detectors’ data logs provided complete audit trails, helping Nordic Seafoods renew its contracts with major European supermarket chains.
“Before the Fanchi-tech metal detector, we were constantly fighting false rejects and compliance concerns,” says Nordic Seafoods’ Quality Control Manager. “Now, the system reliably detects contaminants in every product, even high-moisture seafood, and we’ve eliminated both waste and compliance risks. It’s been a game-changer for our business.”
The Fanchi-tech Conveyor Metal Detector is more than just a piece of equipment—it’s a comprehensive solution for meat and seafood processors looking to protect consumers, reduce waste, and ensure compliance with global food safety standards. Whether you’re upgrading a single line or implementing plant-wide quality control, Fanchi-tech provides tailored support from initial consultation to installation, training, and ongoing technical service.
