Drop-type Metal Detector

Efficient Metal Detection Solution for Food Packing Production Lines

The Throat Metal Detector is specially designed for vertical packaging machines and free-fall production lines. It provides high-sensitivity metal contamination detection before product sealing, effectively ensuring food safety and product quality.

Equipped with a high-performance detection system, the machine can reliably detect ferrous, non-ferrous, and stainless steel contaminants. It is widely used for granules, powders, nuts, seeds, snack foods, and frozen food applications.

Product Features

High Sensitivity Detection

Accurately detects small metal contaminants, reducing the risk of missed detection and improving product safety.

Suitable for Free-Falling Products

Specially designed for online inspection of granules, powders, and bulk materials before packaging.

Compact Structure and Space Saving

The throat-type structure can be directly installed at the discharge point of packaging machines, saving production space and allowing easy integration into existing lines.

Automatic Alarm and Machine Stop Function

When metal contamination is detected, the system automatically triggers an alarm and outputs a stop signal to prevent defective products from entering the market.

SUS304 Food Grade Stainless Steel Body

The entire machine is made of SUS304 stainless steel with a stable structure, easy cleaning, and compliance with food industry hygiene standards.

Stable Operation with Low False Alarm Rate

Designed with strong anti-interference capability to ensure stable performance in complex production environments.

Application Range

Grains and Seeds
Nuts and Dried Fruits
Snack Foods
Oats and Muesli
Powder and Granular Products
Frozen Foods
Pet Food

Suitable for Metalized Packaging Materials

For packaging materials containing metal components, such as aluminum foil bags, traditional finished-product metal detectors are often unable to perform accurate detection.

The throat metal detector can directly inspect raw materials before packaging, effectively avoiding interference caused by the packaging material itself.

It is especially suitable for puffed food and snack food production lines using aluminum foil packaging bags, providing more reliable metal detection before sealing.

System Advantages

Compared with traditional conveyor metal detectors, the throat-type metal detector is more suitable for free-flowing products. It performs metal detection directly before sealing, reducing product waste while improving detection efficiency and production stability.

The system can be flexibly integrated with vertical packaging machines, premade pouch machines, and multihead weighers, providing a more efficient and reliable inspection solution for food packaging production lines.
