Patent ID: 6921194

Claim:
A device for mixing a flowable or pourable medium, the device comprising a container ( 1 ) receiving the medium; a rotatable shaft ( 2 ) having substantially radially projecting support arms ( 4 ) and rotatable in a direction of rotation; at least two mixing elements ( 5 ) connected to the substantially radially projecting support arms ( 4 ); wherein the at least two mixing elements ( 5 ) are tubular and formed as coil-shaped spirals ( 6 ) conically shaped at least across a partial length of the coil-shaped spirals ( 6 ), respectively; wherein the coil-shaped spirals ( 6 ) have a first end face and a second end face, respectively; wherein the first end faces pointing in the direction of rotation have a cross-section greater than a cross-section of the second end faces; wherein the coil-shaped spirals ( 6 ) have a central axis (M), respectively, having a slant angle (α) relative to a plane of rotation of the at least two mixing elements ( 5 ); wherein the support arms ( 4 ) and the coil-shaped spirals ( 6 ) connected to the support arms ( 4 ), respectively, are formed of a single wire as a monolithic part, respectively.
