Abstract
A continuously operating sugar centrifuge has a centrifugal basket with three stages including a preseparating stage, an intermediate meshing-in and washing stage, and a separating stage proper. The intermediate stage has three zones, namely a first zone without any perforations or screens and with a cylindrical or somewhat inwardly inclined wall, adjacent to the preseparating stage, a second cylindrical or slightly outwardly inclined intermediate zone with a screening area in which the openings take up 2% maximum and a third zone having a wall with a 10.degree. outward inclination at the most which merges into said separating stage and which carries a screen having the largest possible screen openings. A liquid supply device is arranged to feed liquid into the intermediate stage.
Claims9
In a basket structure for a continuously operating sugar centrifuge into which massecuite is continuously supplied by feeding and accelerating means including a preseparating stage and a further separating stage, the improvement comprising washing stage means arranged between said preseparating stage and said further separating stage, said washing stage means comprising three zones including a juicing-up zone, an intermediate zone and a separating zone, arranged in that order as viewed in the flow-direction of the material being centrifuged, said juicing-up zone having impermeable and unperforated wall means with a radial spacing from said preseparating stage, said intermediate zone comprising first separating screen means with an open screening area of maximal 2% of its total area, said separating zone comprising wall means having a radially outward inclination of up to 10.degree. relative to the vertical, whereby the separating zone has an outwardly flaring upper end, said separating zone further comprising second screen means having a maximum of open area relative to its total area, said upper end of said separating zone merging into said further separating stage, and washing liquid supply means operatively arranged for feeding washing liquid into said juicing-up zone.
