ABSTRACT:
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.degree. to 7.degree. 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.
