A characteristic of one of the crystals in the two-component mixture is measured to assess the mixture quality. At a computer (8) the measurement is compared with a stored desired value, a yardstick for the required mixture quality. In accordance with the result, the ratio of the components is adjusted. Also claimed is the device for the above process. A line (3) carrying the solution is followed by a crystalliser. Two further supply lines (1,2) for the components, feed the line (3). The supply lines have flow controls (4,5) connected to a computer unit (8), receiving the output of a sensor in the line. USE - Used to determine the quality of a sugar solution. ADVANTAGE - An early and reliable indication of the quality of the crystal mixture can be obtained. Continuous measurement is achieved. Standard control methodology and measurements are used.de608670Verfahren zur Bestimmung der Qualitaet eines Kristallgemisches, insbesondere von Zucker, sowie Vorrichtung zur Durchfuehrung eines solchen VerfahrensQuality determination and control of crystal mixture e.g. for sugar production - comprises measuring e.g. colour, pH, etc. as quality determinant and comparing by computer with desired value to adjust slide valves supplying mixture components.patent1996-19612313
