Device for mixing a flowable or pourable medium, especially a highly viscous medium

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.
