Abstract
An agitator for a fermenter, a fermenter and method of operating a fermenter are provided. The agitator has an agitator shaft which stands roughly vertically in the fermenter. Because of this, the substrate in the fermenter is circulated in horizontal planes. This allows the formation of several layered decomposition zones. In addition, the agitator is preferably designed so that it may be removed upwards from the fermenter during continuing operation. This means that it is not necessary to empty the fermenter for maintenance work on the agitator.
