Abstract

A stirring device of a plug-flow fermentation device includes a shaft rotatable about an axis of rotation which defines an axial direction. The stirring device further includes a boundary stirring element that defines the axial extent of a stirring volume covered by the stirring device. A nearest neighbor of the boundary stirring element in the axial direction has an axial maximum width which is smaller than an axial maximum width of the boundary stirring element and which is larger than an axial maximum width of a next-nearest neighbor of the boundary stirring element.
