Fortress dual lane combi doubles down on dairy inspection waste

Fortress Technology has custom-engineered a twin aperture metal detector and dual lane Raptor checkweigher for one of the world’s premium dairy companies, helping to halve waste.

Receiving shredded cheese pouches directly from a dual head bagger, the design unlocks space and cost savings for the dairy plant.

Offering a customized solution, the twin lane conveyor configuration consolidates a single Fortress metal detector divided into two apertures and two independent weight verification Raptor checkweighers for optimized quality control. Each technology and lane has its own air blast reject mechanism to isolate metal contaminants and weight rejects, helping reduce and minimize good product being wasted by more than 50%. Measuring 10ft in length, Fortress also integrated a radius conveyor into the metal detector infeed.

European commercial manager Jodie Curry said, “The high-spec Fortress multi-aperture system was engineered specifically to ensure that there was no trade-off in terms of performance and metal detection sensitivity. One of the key benefits of a twin aperture system is the halving of waste caused by rejects. “.

The special dual-lane version of Fortress Technology’s multi-aperture metal detector comprises a single unit split into two smaller dedicated apertures for each lane that act as independent metal detectors. For optimal metal detection sensitivity the two apertures – measuring 102mm in height by 254mm wide – means packs pass individually through the center point of the metal detector.
