Das Rührrad 5 weist stirnseitig zwei parallel zueinander angeordnete Scheiben 12 und 13 auf, zwischen denen eine Anzahl von Rührschaufeln 14 angeordnet ist. Die Scheiben 12 und 13 sind nach Art einer Fachwerkkonstruktion mit einem Umfangsband 15 und mehreren Speichen 16 ausgebildet. Das Rührrad 5 bildet auf diese Weise eine Anordnung nach Art eines drehbaren Käfigs, der im weitesten Sinne an ein an sich bekanntes Wasserrad erinnert. Im Gegensatz zu bekannten Wasserrädern sind die Rührschaufeln 14 zwischen den Scheiben 12 und 13 schräg angeordnet, so dass das angetriebene Rührrad 5 der im Fermentationsbehälter 1 befindlichen Biomasse einen vorbestimmbaren Drall versetzen kann. Die Rotation der flüssigen bis teigigen Biomasse im Fermentationsbehälter 1 kann durch die gezielte Ausrichtung der Rührschaufeln 14 beeinflusst werden. Die einzelnen Rührschaufeln 14 können aus mehreren Rührelementen 17 bestehen, oder aber auch einstückig ausgeführt sein. Die mehrteilige Ausführung der Rührschaufeln 14 begünstigt den Austausch von fehlerhaften Rührelementen 17, da bei Beschädigungen nicht unbedingt die komplette Rührschaufel 14 ausgetauscht werden muß.
