Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Decken des Zuckers in einer Zentrifuge, vorzugsweise einer Kontinuierlichen Zentrifuge, wobei zur Säuberung des Zuckers auf die sich auf der Innenwand der Zentrifugentrommel befindliche Zuckerschicht eine Flüssigkeit, vorzugsweise Wasser gesprüht wird. Zur Verbesserung der Zuckerverarbeitung wird erfindungsgemäß vorgeschlagen, daß der von der Zuckerschicht nicht aufgenommene, von ihr reflektierte Flüssigkeitsnebel in unmittelbarer Nähe des Aufsprühbereiches abgesaugt und aus dem Trommelinnenraum nach außen abgeführt wird.The invention relates to a method and an apparatus for Cover the sugar in a centrifuge, preferably a continuous one Centrifuge being used to clean up the sugar the one located on the inner wall of the centrifuge drum Sugar layer sprayed a liquid, preferably water becomes. To improve sugar processing, the invention suggested that the one not absorbed by the sugar layer, liquid mist reflected by it in the immediate vicinity Aspirated near the spray area and out of the drum interior is discharged to the outside.
