A high frequency metal detector has been developed which offers food manufacturers and packers heightened sensitivity for non-ferrous and stainless steel contaminants -- up to 30% higher than standard detectors.

Flakes or slivers from machinery as well as swarf or wire from sieves, cutters or drilling during maintenance work can infiltrate the line at any stage during the production process. It is the non-ferrous metals and stainless steel alloys that pose major challenges to standard metal detectors.

Lock Inspection Systems' detector is based on its MET 30+. The MET 30+ hf detector remains robust and reliable at peak sensitivities by employing a single high frequency, crystal controlled oscillator.

Designed primarily for snack food and bakery industries, the unit will inspect dry foods such as biscuits and crisps at 875kHz -- four times more than standard food industry detectors. It eliminates the need to reconfigure the settings for each product, reducing downtime while increasing efficiency and operating speeds.

The system is currently available as a horizontal unit, employed at the end of the line for final screening of dry, polywrapped, finished products.

Lock is also developing a Waferthin model for space-restricted lines as well as a Vertical Fall option for free-flowing goods such as coffee granules, sugar and cocoa later this year.
