Case Study: Conveyor Metal Detector for Food Processing

How Fanchi-tech Helps Food Manufacturers Improve In-Line Metal Contamination Control

Metal contamination can occur during food processing due to equipment wear, cutting operations, machinery components or raw-material handling. For manufacturers supplying retailers and food brands, detecting metal contaminants before products leave the production line is a critical part of a robust food safety process.

For this application, Fanchi-tech provides a conveyor metal detection solution designed for continuous inspection of packaged food products.

Application: Continuous Metal Detection on a Food Production Line

The pictured system uses a conveyor-based inspection configuration, allowing products to pass automatically through the metal detection tunnel during production.

For applications such as packaged meat, frozen food, seafood, snacks and other processed food products, the key requirement is not simply detecting metal. The system must also integrate smoothly with the existing conveyor line and remove contaminated products without unnecessarily interrupting production.

A typical inspection process is:

Product Infeed → Metal Detection → Automatic Reject → Qualified Product Outfeed

This configuration gives production teams a clear and repeatable control point for metal contamination.

Why Conveyor Metal Detection Matters

Food manufacturers commonly need to control potential physical hazards introduced during processing. FDA guidance identifies metal fragments as a physical hazard that may originate from processing equipment, including cutting and mechanical operations.

A properly integrated conveyor metal detector can help manufacturers:

• Detect ferrous and non-ferrous metal contamination
• Inspect products automatically during continuous production
• Remove rejected products from the production flow
• Reduce dependence on manual inspection
• Create a more consistent foreign-body control process

For export-oriented food manufacturers, foreign-body detection can also form part of the broader food safety system expected by customers and certification programmes. BRCGS Food Safety Issue 9 specifically includes foreign-body detection and removal equipment within its food safety guidance.

Recommended Applications

Based on the conveyor configuration shown in this application, the solution is particularly suitable for:

Packaged Meat & Poultry
Processed meat, chicken portions and other packaged products moving continuously on a conveyor.

Frozen Seafood & Frozen Food
Products requiring automated inspection before packing, boxing or dispatch.

Snack & Processed Food
Bags, trays and other packaged food products where high-throughput inspection is required.

The final metal detector specification should be selected according to the product type, product effect, package size, conveyor width, line speed and required detection sensitivity rather than using one standard configuration for every product.

Why Fanchi-tech

Fanchi-tech focuses on industrial inspection equipment for food and manufacturing applications, including Industrial Metal Detectors, Online Checkweighers, X-ray Inspection Systems and Combination Inspection Systems.

For food processors, the objective is straightforward:

Reliable inspection. Automatic rejection. Easy integration. Better control of production-line quality.

Our engineers can configure the metal detection system according to your actual product and conveyor requirements.
