Abstract

Die Erfindung betrifft ein Verfahren sowie eine Vorrichtung zum Ausräumen des abgeschleuderten Produktes aus der Zentrifugentrommel einer diskontinuierlichen Zentrifuge, wobei ein Schälmesser (7) in die abgeschleuderte Produktschicht (9) eingeschwenkt wird und hier mit einer gegen die Trommeldrehrichtung (5) gerichteten Schneide (7a) das Produkt abschält. Zur Optimierung des Produktaustrages wird erfindungsgemäß vorgeschlagen, daß das Schälmesser nach seinem Einschwenken über nahezu die gesamte Trommelhöhe Produktkontakt hat, gleichzeitig über die gesamte Trommelhöhe das Produkt von der mit Räumdrehzahl rotierenden Produktschicht schichtweise abschält und bei Erreichen des Trommelsiebes wieder ausgeschwenkt wird.

The invention relates to a method and a device for removing the centrifuged product from the centrifuge drum of a discontinuous centrifuge, a peeling knife (7) being pivoted into the centrifuged product layer (9) and here with a cutting edge (7a) directed against the direction of rotation of the drum (5). the product peels off. To optimize the product discharge, it is proposed according to the invention that the peeling knife has product contact after it has been swiveled in over almost the entire drum height, and at the same time peels off the product layer by layer over the entire drum height and is swung out again when the drum screen is reached.
