A centrifuge

1,111,557. Centrifugal separators. ALFALAVAL AKTIEBOLAG. 22 March, 1967 [24 March, 1966], No. 13375/67. Heading B2P. In a centrifuge for separating two liquid components from each other, one of the components being highly viscous, the outlet for one of the components is hermetically connected to a stationary pipeline 7 in which is inserted a displacement pump 8 whose throughput capacity can be adjusted during operation of the centrifuge. The pump 8 which may be of the motor-driven gear type and may be controlled by a known device 9, is preferably inserted in the outlet pipe for that component which is present in a smaller quantity. When treating a glucose-containing corn starch hydrolysate, for example, a glucose-containing heavy liquid is discharged through a pipe 6 while a highviscosity, fat and protein-containing light liquid is discharged through the pipeline 7.
