Products on the four lane multi-aperture metal detector travel through a single search head with four apertures.


Product is randomly presented to the food metal detector where it is separated into four lanes which travel through a single search head. The Fortress search head is comprised of four separate apertures with a single item being inspected by each one.

The main advantage of this approach is that there is only minimal widening of the conveyor belt to accommodate a single search head as opposed to installing four individual food metal detectors.

All four heads are controlled from the one control panel which streamlines operator access. Individual items are inspected and rejected via a raise flap reject system in to a reject bin.

The Fortress food metal detector establishes a new industry standard and is capable of detecting down to 0.3mm ferrous, 0.4mm non ferrous and 0.5mm stainless steel.
