Abstract (en)
[origin: WO2008055456A1] Method and apparatus for determining the homogeneity (3) of a mixture. Known mixing methods require multiple calibration passes in order to automatically determine the end point of a mixing operation. This signifies a high level of complexity in the case of continuously changing products. The object of the present invention is to make it possible to automatically determine the end point of a mixing operation without having to carry out calibration passes. This is achieved by creating continuous spectral analyses of the mixture. As soon as the variance is under a tolerance (8) over a predefinable amount of time, the mixture is deemed to be homogeneous. The invention also relates to the determination of the end point of a mixing operation and to substance classification.
