HACCP & FDA Grade Conveyor Belt Type Food Metal Detector
**HACCP & FDA Grade Conveyor Belt Type Food Metal Detector**
In the food production industry, metal contamination is one of the most common and dangerous risks. It can be introduced at any stage of the process, often through machinery, handling equipment, or utensils. A high-quality food metal detector plays a crucial role in ensuring the safety and integrity of both packaged and unpackaged products by identifying metal contaminants during processing or packaging. This helps prevent harmful materials from entering the food supply chain.
Â
Types of Contaminants
Food metal detectors are capable of detecting three main types of metallic contaminants:
Ferrous metals
Non-ferrous metals
Stainless steel, which depends on magnetic or conductive properties
Â
The detection capability of a conventional metal detector in the food industry is influenced by the conductivity and magnetic permeability of the contaminant:
Ferrous metals are both magnetic and conductive, making them easy to detect.
Non-ferrous metals are not magnetic but are good conductors, allowing for relatively easy detection.
Stainless steel is more challenging to detect because it is usually non-magnetic and has poor electrical conductivity. Its detection becomes even harder if the product is wet or contains high levels of salt.
Â
For non-metallic contaminants such as glass, calcified bone, ceramics, or stone, an X-ray inspection system offers better detection capabilities.
Â
Key Features:
l       Dual-channel dual-frequency detection system for improved accuracy.
l       Supports up to 20 different product settings for accurate detection.
l       IP65 rated for dust and water resistance, ideal for industrial environments.
l       Complies with FDA standards, suitable for direct inspection of unpackaged food items.
Â
Specifications:
Material: 304 stainless steel for the detector, 201 stainless steel for the frame, and PVC/PU white belt.
Belt Length: 1600 mm (customizable).
Conveyor Height: 650 mm + 100 mm adjustable feet, with wheels for mobility.
Alarm System: Buzzer and warning lights for immediate alerts.
Rejection Systems:
l       Stop-on-Detect Reject (≤50 kg) – Stops the conveyor when metal is detected, enabling operators to remove contaminated products.
l       Pusher Reject (≤10 kg) – Pneumatic pushers divert contaminated products out of the flow.
l        Flap Reject – End flap or lift flap mechanism used for dry bulk products. Triggers to divert contaminated items from the good product flow.
Flow Speed: Fixed at 25 m/min or variable between 10–40 m/min.
Flow Direction: Left to right or opposite (facing the control panel).
Language Support: English, Spanish, Chinese.
Power Supply: AC 110V/220V, 50/60Hz, power consumption: 90/120/200W.
Aperture / Sensitivity:
Note: The sensitivity values listed above are based on empty-load testing. Actual performance may vary depending on the product being tested.
