According to the company, Unisort Film uses the so-called Active Object Control (AOC) technology. It’s a stabilizing system that uses airflow to influence the material being sorted on the belt, enabling a degree of control over the material’s flight parabola in the area of the catcher hood. The material is analysed and classified by a near infrared camera that works using Hyperspectral Imaging Technology (HSI). The material is sorted out a compressed air system with a nozzle bar equipped with high-speed-valves.
Unisort Black basically functions in the same way as the standard Unisort. But due to the use of HSI technology and a more complex evaluation of the spectrum, it is now possible to recognize objects without a spectrum and soot-blackened objects of down to 200 millimetres in size.
