Abstract:
A stirring staff arrangement (29) for being connected to a stirring machine that can be combined with a container (20) for receiving liquids, wherein the container, in an upper bottom wall (26), has a filling opening being closable with the help of a lid (28) for filling the container, wherein the stirring staff arrangement has a bar-shaped stirrer element carrier (30) embodied as a hollow shaft for receiving a stirring machine shaft, and stirrer elements (32) coupled to the stirrer element carrier so as to be pivotable, in such a manner that the stirrer elements have been pivoted, in a mounting configuration, with a free stirrer element end, against an axis of rotation of the stirrer element carrier, wherein a spring means is arranged between the stirrer elements and the stirrer element carrier, in such a manner that the stirrer elements, in an operating configuration, are charged with centrifugal force as a consequence of a rotation of the stirrer element carrier and take a pivoted position that depends on the rotational speed of the stirrer element carrier, a stirring angle δ being realized with respect to the axis of rotation, wherein the free stirrer element ends are arranged at a stirring distance r from the axis of rotation and the spring force, which increases as the stirring angle grows, opposes the centrifugal force.
