Abstract

In accordance with embodiments of the herein disclosed subject matter it is described a stirring device (100) comprising a shaft rotatable about an axis of rotation; a stirring element (106) attached to the shaft, the stirring element (106) having a recess (108); the recess (108) having a surface portion (114) and an edge (116), the edge (116) defining an opening which provides access to the surface portion (114); the recess (108) being spaced from the shaft, wherein a rotation of the shaft defines a moving direction (120) of the recess (108) in which the edge (116) forms a leading edge of the recess (108); the surface portion (114) defining a depth (122) of the recess (108) with regard to the edge (116); and wherein in a direction (124) radially inwardly the depth (122) of the recess (108) is decreasing. In accordance with embodiments, the decreasing depth (122) may be realized by a suitable inclination (136) of the surface portion (114) of the recess (116) and/or by a suitable inclination (140) of the edge (116) of the recess (108).
