Metal Detection

Metal detectors are most commonly used by the food, pharamaceutical and chemical industries for the final inspection and removal of contaminated product at the end of process lines

A metal detector consists of the detection head (or coil) and electronic control equipment that interprets signals sent from the detection head.

Contaminated product can be removed from the process line by one of the following reject mechanisms:

• Push/pull paddle
• Diverter flap
• Swing arm
• Air blast system
• Drop away/retracting belt
• Pneumatically activated flap/valve
• Special reject system

Total Foreign Body Detection and Removal

Metal detectors are often used with magnetic separators to provide full foreign body detection (FBD). Typically magnetic separators are used at product input and at key points along the process line, continuously removing ferrous and para-magnetic contamination from the ingredients and product. Metal detectors remove metal contaminated product itself.
