ABSTRACT:
A separation device with a transparent separation chamber, whereby a direct light source illuminates the components to be separated and the individual components reflect the light intensity as a function of their individual coloring (brightness) via optics onto a linear group of photodetectors. The signals received by the detectors are forwarded to a computing unit in which they are processed. A regulating unit, which operates very precisely due to the accuracy and the high speed of the receiver and computing unit, is controlled according to a program and thus assures optimum separation performance of the separation device.
