ABSTRACT:
In a method and apparatus for eliminating liquid components and fine-grained components from a sugar suspension, control variables for controlling the centrifuge are obtained from a measurement of the quantity of material per unit of surface area in the filter cake formed in the centrifuge during the centrifuging process. In particular, a radiometric measurement can be used for this purpose. From the time course of the measurements obtained, relationships with the physical composition of the filter cake at the instant of measurement are derived and used to adjust process control variables, such as the quantity of water to be added and the length of the washing phase. The control of such a process can be made fully automatic, with optical quality, using a single continuous measurement.
