Abstract (en)

[origin: EP0164303A2] In this stirring device, the energy in the form of shear forces and transport forces is introduced by the rotary motion of a paddle stirrer, whose shaft (2) or rotation axis is mounted eccentrically to the centre (7) of the container bottom under an acute angle (30) to the stagnant liquid level (10, 11, 12), the paddles (6) during the rotation forming the generated surface of a cone in such a way that the generatrix thereof runs parallel to the container bottom at a small distance or almost touches the latter. <IMAGE>
