The hyper-detect^® from tna and Safeline is the world’s first non-symmetrical balanced coil metal detector with a conical aperture into the detector.While conventional ‘throat’ metal detectors have long been used in the industry to inspect the product before it enters the bag to allow the use of metallised film, packaging speeds have been limited until now. The revolutionary integrateddesign of the hyper-detect^®allows the metal detector to be positioned much closer to the multi-head weigher, dramatically increasing the speed at which the bagger can produce finished bags.

With a high frequency function, the hyper-detect provides stable operation for optimum sensitivity and consistent performance when inspecting products. Able to detect ferrous contaminants from 0.8mm to 0.9mm, non-ferrous pieces up to 1.0mm and even non-magnetic stainless steel from 1.0mm to 1.2mm, the hyper-detect is extremely sensitive, greatly reducing the risk of contaminants entering the value chain, safeguarding consumer safety and the company’s reputation.

The hyper-detect^® metal detector and bagger integration takes place on two levels. Mechanically, the detector and chute work together to provide a fully optimised path for the product to travel down, offering greater control and repeatability for faster product transfer and reduction in rejects. At the same time, operator control is integrated into the tna robag^® product and operational screens allow for a single set-up of the whole system, leaving no room for error, and offering real productivity and cost improvements.
