Abstract

Es wird ein Rührorgan, insbesondere zum Dispergieren von Gasen in Flüssigkeiten angegeben, welches eine Mehrzahl Rührblätter (14) hat. Zur Verkürzung der Mischzeit und Herabsetzung des Leistungsabfalls weist jedes Rührblatt (14) einen in Drehrichtung nach vorne abgebogenen Abschnitt (20) auf. Der abgebogene Abschnitt (20) kann an seinem in Drehrichtung gesehen vorderen Endbereich einen beispielsweise etwa dreieckförmigen Endabschnitt (22) aufweist, der einen Winkel (γ) zum ebenen Teil (28) des abgebogenen Teiles (20) bildet, und vom Rührblatt (14) weg gerichtet ist.
