Centrifugal filters are commonly used in the food processing and chemical industries in order to separate the liquid and

solid phases of a mixture.  Essential design criteria for successful drying of granular particles in a conical continuous centrifugal filter are proposed. Four criteria are considered: minimum flow thickness (to ensure sliding bulk flow rather than particulate flow), desaturation position, output dryness and basket failure. The criteria are based on idealised physical models of the machine operation and are written explicitly as functions of the basket size, spin velocity and input flow rate. The separation of sugar crystals from liquid molasses is taken as a case study and the regime of potential operating points is plotted.
