Metal Detectors
Metal detectors are an essential tool in food inspection, used to detect metallic contaminants that may have accidentally entered food during processing or packaging. They are designed to identify and reject any metal contamination before it can reach consumers, ensuring the safety and quality of food products. We offer a variety of metal detectors from a number of vendors including A&D, Fortress, and Minebea.

Custom Configurations
Conveyor Metal Detectors
This type is the most common kind, and the first to come to mind: a metal detector integrated with a conveyor belt. The metal detector is usually located at the end of the conveyor belt and can detect metallic contaminants in packaged or unpackaged food items. These metal detectors are very efficient and can detect even small metal particles. They are easy to install and can be integrated into existing production lines.
Pipeline Metal Detectors
This type of metal detector is used in food processing industries where products are transported through pipelines. The metal detector is installed in the pipeline and can detect metallic contaminants in liquids or slurries. Pipeline metal detectors are designed to be easy to clean and maintain, and they can be customized to suit specific product and pipeline configurations.
Gravity-Fed Metal Detectors
This type of metal detector is used in the packaging industry, where products are dropped through a metal detector before being packaged. Gravity-fed metal detectors are easy to use and can detect metallic contaminants in a wide range of products, including dry, powdered, or granular products.
Custom Reject Systems
We can integrate any reject system into virtually any metal detector, regardless of brand.
Air blast reject system
This system uses a blast of compressed air to remove contaminated products from the production line. It is ideal for high-speed lines and can remove products without causing damage. The system is also suitable for handling delicate products, such as fruits and vegetables.
Pusher reject system
This system uses a mechanical arm to push contaminated products off the conveyor belt. The pusher arm is activated by a signal from the metal detector, and it can remove products quickly and efficiently.
Drop-down reject system
This system uses a series of air-operated pistons to drop contaminated products from the production line. It is suitable for handling heavy products, such as meat or cheese, and can remove them without causing damage.
Belt-stop reject system
This system stops the conveyor belt when a contaminated product is detected. It is suitable for low-speed lines and is ideal for handling large and heavy products.
Diverting reject system
This system diverts contaminated products to a separate reject channel or bin. It is ideal for handling small and light products and can remove them without causing damage.
