Conveyor Metal Detector : Improving Food Safety Control in Cheese Production Line

1. Industry Background: Increasing Demand for Food Safety Inspection in Dairy Processing

The global dairy industry continues to increase its requirements for food safety, production efficiency and contamination prevention.

Cheese manufacturers, especially those supplying supermarkets, restaurants and international food brands, must maintain strict quality control systems based on HACCP, BRC, IFS and other food safety management standards.

During cheese processing, metal contamination risks may come from:

• Stainless steel equipment wear
• Cutting blades
• Processing machines
• Conveyor components
• Raw material handling systems

Even very small metal particles can cause:

• Customer complaints
• Product recalls
• Brand reputation damage
• Production losses

Therefore, modern dairy factories increasingly require reliable online inspection solutions instead of traditional manual inspection methods.

A conveyor metal detector installed directly on the production line provides continuous inspection capability and helps manufacturers detect metal contamination before products reach customers.

2. Customer Production Challenges

A European cheese processing company produces sliced and block cheese products for retail packaging.

The production process includes:

Raw Cheese Material
↓
Cutting Process
↓
Forming
↓
Cooling
↓
Packaging
↓
Final Inspection

The customer faced several challenges:

1. High contamination risk during cutting process

Cheese production equipment contains:

• Cutting knives
• Stainless steel components
• Mechanical moving parts

Long-term operation may create metal fragments.

2. Manual inspection could not guarantee 100% inspection

Before installing an automatic inspection system, operators mainly depended on:

• Visual checking
• Random sampling

However:

• Sampling cannot inspect every product
• Human inspection efficiency decreases during long production hours
• Small metal contamination may be missed

3. Need for continuous production line integration

The customer required:

• Automatic online detection
• Easy cleaning
• Stainless steel construction
• Integration with existing conveyor system
• Automatic reject function

3. Why Traditional Inspection Methods Were Not Enough

Traditional quality inspection methods have limitations.

Manual Inspection

Although operators can visually check product appearance, metal particles inside products cannot be identified.

Sampling Inspection

Sampling inspection only checks selected products.

For high-volume cheese production:

Thousands of products pass through the production line every day.

A sampling method creates potential food safety risks.

Production Efficiency Issues

Stopping production for inspection affects:

• Output capacity
• Labor cost
• Delivery schedule

Therefore, the customer needed an automatic food safety inspection solution capable of checking every product.

4. Fanchi-tech Solution: Conveyor Metal Detector for Cheese Production Line

To solve the customer's food safety challenges, Shanghai Fanchi-tech Machinery Co., Ltd. provided a customized Conveyor Metal Detector solution designed for dairy and frozen food production environments.

The equipment shown in the application image is a stainless-steel inline metal detection system installed directly on the production conveyor.

The solution focuses on:

• Continuous online metal contamination detection
• Food-grade hygienic design
• Automatic reject control
• Stable operation in harsh production environments
• Integration with existing processing lines

The system detects potential metal contamination including:

• Ferrous metal
• Non-ferrous metal
• Stainless steel fragments

During production, every cheese product passes through the detection area.

If metal contamination is detected, the system automatically activates the reject mechanism to remove contaminated products before packaging and shipment.
