Abstract (en)

[origin: DE19714115A1] The invention relates to a device and method for optically detecting the presence of ingredients of a pourable product by NIR-spectroscopy. In order to obtain reproducible measured results, the device is characterized in that the product flows in the direction of gravitational force, a valve (8) is fitted in the duct downs tream from the measuring window (6), and the valve can be moved into closed position by a control system, at least for the duration of measuring. The method is characterized in that the product flows in the direction of gravitational force past a measuring point, is retained downstream from the measuring point such that the flow comes to a standstill at the measuring point, and, after measuring, the product is removed from the banked-up stretch.
