metal detector for food inspection - GFMD

TARGET MICRO SCAN Metal Detection Systems are designed to meet the strict demands of the bulk food and packaged food industries monitoring for metal impurities.

Our metal detectors operate on the inductive measuring principle. A high frequency electromagnetic alternating field is generated. If a metal object passes through the metal detector, the detector experiences a change in the field based on the magnetic and electrical properties of the metal object. All types of metals (i.e. non-ferrous, ferrous and stainless) are detected.

The metal detector is integrated with a conveyor. Metal passing through the metal detector unit will be detected and optional devices can be used to reject the contaminated product. Metal detectors can be integrated with existing production lines or provided with a conveyor specifically matched to the requirements. Basic systems can be built with a simple stop alarm whilst more sophisticated designs can include failsafe systems to ensure contaminated product is rejected.

Automatic Reject Devices
Automatic rejection systems are designed as an integral part of the conveyor metal detector package. A wide variety of rejection systems can be used on any conveyor, as shown in the following illustrations, to insure contaminated product is removed without disruption to product flow. Contaminated product will be automatically rejected without impeding product flow.

Design Considerations

• Product flow should allow for evenly spaced products; this will minimize the number of products rejected when metal has been detected.
• Reject mechanism should be fast enough and strong enough to remove product without disturbing product flow
• Belting should be matched to environment and reject concerns
• Product transfer between metal detector conveyor and existing conveyors
