Abstract (en)
[origin: US4762570A] The screen drum of a continuously operable sugar centrifuge is divided into three sections along its axial length from the drum bottom to the sugar discharge rim. A first upper section extends from the discharge rim downwardly. This first section has such a wall inclination ( alpha ) relative to the central rotational axis that a layer of material being centrifuged remains stationary on the first section when the supply of massecuite is interrrupted and the supply of covering or wash-water is continued while the centrifuge keeps operating. A second mid-section extends along a mid-portion of the drum and another angle of inclination ( beta )relative to the rotational axis, whereby the angle ( beta ) is larger by about 3 DEG to 7 DEG than the angle ( alpha ). A third lower section encloses a third angle ( gamma ) with the rotational drum axis. The third angle ( gamma ) is about equal to the first angle ( alpha ). A so constructed drum facilitates the control of variables which influence the distribution of the massecuite on ther inner surface of the screen drum. Specifically a more uniform distribution of the material on the inner drum surface is obtained with a layer thickness tapering toward the discharge rim.
