Drop-type Metal Detector

For Vertical Packaging Machines and Free-Fall Products

The throat metal detector is mainly used together with vertical packaging machines to detect metal contamination in products before packaging.

It is suitable for free-flowing materials such as grains, snacks, powders, seeds, nuts, and frozen food products.

The compact structure allows the detector to be installed directly below the weigher or above the packaging machine, saving installation space and making integration easier.

Technical Specification

Applications

• Rice and grains
• Seeds and cereals
• Nuts and dried fruits
• Snack food
• Powder products
• Frozen food
• Pet food

Application Advantage

For products packed with aluminum foil bags or other metalized packaging materials, traditional finished-package metal detectors are often difficult to use.

The throat metal detector performs inspection before packaging, so the packaging material does not affect the detection result.

This makes it suitable for puffed food snack food and other products using aluminum foil packaging.

Integration

The detector can work together with:

• Vertical form fill seal machines
• Multihead weighers
• Premade pouch packaging machines
• Automatic packaging lines

When metal contamination is detected, the detector outputs a relay signal to stop the packaging machine or trigger an alarm.

Optional Configuration

• Different aperture sizes
• Multi-language interface
• Customized installation structure
• High sensitivity configuration
• Product specific feeding solution

Suitable Products

Suitable for free-flowing bulk products requiring inline metal inspection before packaging.
