Food Industrial Conveyor Tunnel Metal Detector Inspection Systems

Advanced Metal Contamination Detection for Food Safety and Compliance

In today's fast-paced and highly regulated food industry, ensuring metal-free products is crucial not only for consumer safety but also for maintaining brand integrity and regulatory compliance. The Food Industrial Conveyor Tunnel Metal Detector Inspection System is engineered to provide highly sensitive, fully automated metal detection across a wide range of food processing and packaging lines. This state-of-the-art system helps food manufacturers detect and reject ferrous, non-ferrous, and stainless steel contaminants in real-time, significantly reducing the risk of recalls, fines, and damaged reputation.

Whether you're producing baked goods, frozen foods, meats, dairy, grains, or snacks, this metal detector offers exceptional detection accuracy, hygienic design, and seamless integration into existing conveyor lines.

 

What Is a Conveyor Tunnel Metal Detector for Food?

A conveyor tunnel metal detector is an inline inspection system featuring a rectangular detection head (tunnel) mounted over a conveyor belt. As products pass through the tunnel, the system automatically scans for any metal contaminants and instantly activates a reject mechanism if contamination is found.

These systems are essential for HACCP, IFS, BRC, and FDA compliance, helping manufacturers ensure their products meet the highest food safety standards from raw ingredient processing to final packaging.

 

Industries and Applications

The Food Industrial Conveyor Tunnel Metal Detector is widely used in various sectors within the food industry, including:

• Meat and Poultry Processing: Whole cuts, sausages, chicken breasts, ground meat

• Seafood Processing: Fish fillets, shrimp, shellfish, and frozen seafood

• Baked Goods: Bread, pastries, cookies, crackers

• Dairy Products: Cheese blocks, butter, yogurt packages

• Frozen and Ready-to-Eat Foods

• Snacks and Confectionery: Chips, chocolates, candy bars

• Dry Goods and Grains: Flour, sugar, rice, spices

• Fruits and Vegetables: Fresh and frozen produce

• Pet Food and Animal Feed

 

Key Features of the Food Conveyor Tunnel Metal Detector System

1. Multi-Frequency Digital Signal Processing (DSP)

The system utilizes multi-frequency technology to adjust detection frequencies based on the product's characteristics. This ensures optimal sensitivity across wet, dry, and conductive products, reducing false rejects and enhancing reliability.

2. High Sensitivity to All Metal Types

Capable of detecting ferrous, non-ferrous (aluminum, brass), and stainless steel contaminants as small as 0.3 mm, depending on aperture size and product effect.

3. Intelligent Auto-Learn Function

Quick product setup using an auto-learn algorithm optimizes settings for different products, reducing downtime during changeovers and minimizing operator training requirements.

4. Hygienic Stainless Steel Construction

The system is built with 304/316L stainless steel, IP66 or IP69K rated, suitable for wet washdown environments. It's ideal for high-hygiene areas in meat, seafood, and dairy plants.

5. Customizable Aperture Sizes

Tunnel openings can be adjusted to match product size and conveyor width, optimizing detection sensitivity and line compatibility.

6. Integrated Reject Mechanisms

Choose from various reject systems including:

• Air-blast ejector

• Drop-flap diverter

• Pneumatic pusher

• Retracting belt

• Stop-and-alarm for large bulk items

All reject mechanisms are designed to handle fragile or irregular products without damage.

7. User-Friendly Touchscreen Interface

Operators can easily navigate the 7" or 10" color touchscreen HMI, adjust parameters, view real-time status, and generate inspection reports.

8. Data Logging and Traceability

Built-in data storage and connectivity options (USB, Ethernet, RS485) allow you to log inspection results for regulatory audits and continuous improvement.

How It Works

1. Product Feeding: Food products enter the detection tunnel via the conveyor.

2. Real-Time Metal Detection: As the product passes through the electromagnetic field inside the tunnel, the system scans for any metallic anomalies.

3. Automatic Rejection: If contamination is detected, the product is automatically diverted by the reject mechanism to a reject bin.

4. Data Logging: The detection event is logged with time, product code, and reject status for traceability.

 

Advantages of the Tunnel Conveyor Metal Detector

1. Improved Food Safety

Detect and remove dangerous metal fragments to protect consumers and prevent product recalls.

2. Regulatory Compliance

Easily meet HACCP, BRC, IFS, ISO 22000, and FDA requirements through documented inspection and traceability.

3. Minimized Product Loss

High accuracy means fewer false rejects, reducing unnecessary waste of good products and saving costs.

4. Line Efficiency

Quick product changeover, auto-learn features, and simple controls allow for minimal downtime and high productivity.

5. Robust for Harsh Environments

IP66/IP69K models are built to withstand wet cleaning, temperature extremes, and rugged conditions in food plants.

6. Custom Integration

Compatible with checkweighers, X-ray machines, labeling units, or robotic arms for fully integrated inspection lines.

 

Optional Add-Ons & Customization

• Dual-frequency switching for product effect compensation

• High-speed rejectors for fragile or high-volume items

• Dual-lane or multi-lane designs for parallel production lines

• Lockable reject bins with audit trails

The tunnel metal detector is a system that detects the presence of ferrous materials (steel, iron) in the areas surrounding the tunnel. It can be used for food processing industries and other industrial applications. The most common types of tunnels are those used for transporting liquids, gases and solids.

The tunnel metal detector is an effective way to detect ferrous materials in tunnels that are used for transporting liquids, gases and solids. If you have a process that involves moving liquids through tunnels or pipelines, then you should consider using a tunnel metal detector system to ensure that your material doesn't get contaminated by foreign objects.

Whether you're looking to improve your operations or just want more control over your costs because you aren't paying for unnecessary inspection fees anymore, our products will help you achieve your goals while reducing risk and improving safety. Our detectors are easy to install and operate so there's no need to hire contractors when it comes time to get started on building out your facility's infrastructure.
Food processing tunnel metal detector systems are an essential part of any industrial food facility. The system combines a metal detector and conveyor to ensure that only food is transported through the facility. This ensures that no dangerous materials are allowed to enter the facility, including pathogens such as E-coli, Listeria and Salmonella.

The system can be installed in minutes and is easy to operate. It can be set up with just a few tools and supplies, making it simple for any operator to get started right away. The system works by identifying metals using a sensor placed on the conveyor belt of your processing line. When metal is detected, it sends an alert to your control panel, which stops the conveyor temporarily so that employees can remove any items that may contain contaminants.
