Stealth In-Foil Metal Detector
The Stealth In Foil Metal Detector is an inspection system designed to detect metallic contamination in products packaged with aluminum foil or foil-based trays. It is typically used in food factories and processing facilities where conventional detectors struggle due to foil interference. The system supports contamination control by identifying ferrous and selected metal fragments without being affected by aluminum packaging. It is suited for inline conveyor installation and accommodates a wide range of pack sizes within defined aperture dimensions. The Stealth In Foil Metal Detector is widely deployed across the UAE, GCC, and Middle East food processing sectors.
In UAE production environments such as Dubai and Sharjah, the system is integrated directly into conveyor lines before final packing or secondary inspection points. It operates effectively within temperature-controlled processing rooms and washdown-rated zones when paired with stainless steel conveyor frames. Typical installations support variable belt speeds aligned with packaging lines and aperture sizes matched to product footprint rather than height alone.
The detector interfaces with reject mechanisms including pusher arms or drop-nose conveyors to isolate affected packs without halting production. Its consistent detection performance, combined with stable calibration, supports HACCP control requirements in high-volume food manufacturing and distribution facilities.
Halo Automatic Testing System for Metal Detectors
Halo is suitable for any Fortress metal detector; ideally added at the point of manufacture, it can however, be added to some existing systems.

Frequently Asked Questions
In UAE food factories, in-foil detection is typically required for products packed in aluminum trays, foil wraps, or laminated films. Ready meals, frozen foods, and sealed protein portions produced in Dubai or Sharjah often use this system to maintain inspection accuracy where standard detectors are affected by foil packaging.
The system is installed directly onto existing stainless steel conveyors, usually after sealing and before secondary packing. UAE plants often align belt speed with upstream packaging equipment to maintain inspection stability. Mechanical integration focuses on correct aperture sizing and smooth product tracking through the detection zone.
The detector is specifically designed to suppress foil signal response while maintaining sensitivity to metallic contamination. In high-volume UAE operations, reliable performance depends on consistent pack positioning, controlled belt speed, and correct setup rather than production volume alone.
The system is intended for indoor, temperature-controlled food processing areas common across the GCC. Stable power supply, controlled humidity, and routine cleaning support consistent performance. It is not intended for outdoor exposure or areas with excessive vibration or uncontrolled washdown.
The detector interfaces with automatic reject devices such as pushers or drop-nose conveyors. In UAE plants, these systems divert affected packs into a reject bin while allowing the main line to continue running, reducing downtime and maintaining throughput targets.
Routine checks include cleaning contact surfaces, verifying detector response using certified test pieces, and inspecting reject mechanisms. Many UAE facilities align these tasks with HACCP verification schedules to ensure traceable inspection records and consistent operational control.
