Abstract

The present continuously operating centrifuge produces sugar of uniformly high quality from low grade sugar massecuite of uneven consistency by distributing the massecuite to differing selected levels of a centrifugal screening basket. The distribution level depends on the liquid content characteristics of the massecuite. An accelerating cup is mounted for rotation centrally within the basket for receiving and delivering massecuite to a distributing bell opening downwardly and surrounding the accelerating cup. The distributing bell directs the massecuite toward the tapering wall of the centrifugal screening basket. The lower edge of the distributing bell is vertically adjustable relative to a lower zone of the screening basket for said distributing of the massecuite to different levels of the basket. The centrifugal basket may have several zones. The lower edge of the distributing bell is adjustable relative to a lower zone of the basket from which the area of aperture openings decreases in the upward direction. Adjustment of the vertical position of the distributing bell may be automatically controlled in response to the characteristics of the sugar passing over the upper edge of the centrifugal basket.
