Fortress Technology Customized System Delivers Double Inspection Advantages

Combines twin-aperture metal detector with dual-lane checkweigher for operational efficiency

Fortress Duo Lane Raptor

The Fortress Technology custom-designed, dual-lane Raptor 200 checkweigher is fed by a dual-lane Stealth metal detector to provide quality control, with the ability to work in unison with a dual-head vertical form/fill/seal bagging machine and match output speeds of 120 to 140 ppm. The compatible system utilizes a modular plastic chain radius conveyor belt to provide optimal lane spacing for the dual-aperture detector and meet end user requirements.

The 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 acts as independent metal detectors. While both simultaneously inspect products, the lanes remain programmed to run independently to help to minimize interruption and provide extra inspection and weight verification capacity.

Using air blast nozzles between the two outfeed conveyors, the Raptor checkweigher can independently remove contaminated products into lockable, stainless-steel reject bins. The air blast devices provide quality control by detecting both metal and weight rejects in each lane, whereby contaminants are blasted outward to their retrospective bins that are equipped with sensors.

The Raptor’s load cells can weigh, analyze, capture, and report data simultaneously to ensure traceability and compliance with retailer Codes of Practice and QA protocols. Both the metal detector and Raptor checkweigher capture easy-to-read, live OEE data and benefit from integrated Contact Reporter software.
