Metal Detector Inspection for Food Products with Flap Reject System

Application Overview

In food processing, even small metal contaminants can pose serious safety risks and lead to product recalls. In this case, our metal detection system is used to inspect finished food products on a production line, ensuring compliance with food safety standards and protecting brand reputation.

Product Tested

The metal detector is suitable for a wide range of food products, including:

• Bakery products and snacks

• Meat and seafood products

• Frozen foods

• Packaged and wrapped food items

The system can reliably detect common metal contaminants such as ferrous, non-ferrous, and stainless steel.

Reject Systems Options for Different Applications

To meet different product types, speeds, and installation requirements, our metal detection systems can be equipped with various reject devices, not limited to a single solution. Each reject mechanism is selected based on product characteristics and line layout.

Available reject systems include:

• Flap Reject System: Quickly diverts contaminated products off the conveyor, ideal for packaged food with stable shape and spacing.

• Pusher Reject (Air or Motor Driven): Gently pushes defective products sideways, suitable for cartons, trays, and flow-wrapped items.

• Drop / Falling Reject: Uses gravity to remove contaminated products, commonly applied to free-fall or bulk product lines.

• Retract Belt Reject: Separates products by momentarily retracting a section of the conveyor, effective for fragile or soft food items.

• Air Blast Reject: Uses compressed air to remove lightweight products such as snacks or small packaged items at high speed.

All reject systems are designed to:

• Ensure accurate and timely removal of contaminated products

• Minimize product damage and line interruption

• Improve overall production efficiency and automation level

Our engineers recommend the most suitable reject solution based on your product type, line speed, and installation environment, ensuring stable performance in real production conditions.

Inspection Result

During testing, the metal detector demonstrated:

• High sensitivity and stable detection performance

• Accurate rejection of contaminated products

• Reliable operation under continuous production conditions

This helps food manufacturers maintain consistent product quality while meeting international food safety requirements.
