Patent ID: 7399113

Claim:
An arrangement to produce recipe mixtures, comprising: a mixing vessel sealable by a lid, whose size is matched to the quantity of the recipe mixture: and a mixing tool driven by a drive shaft passing through a sealable central opening of the mixing vessel that possesses friction surfaces that rest against or could rest against at least one inner surface of the mixing vessel under friction pressure, the drive shaft drivable by an adjustable speed motor, wherein the mixing vessel and the mixing tool my move with respect to each other along the axial direction of the drive shaft during manufacture of the recipe mixture, and wherein the mixing tool is a winged agitator with two agitator wings that are displaced with respect to each other along the axial direction and that overlap near the drive shaft, and wherein each of the agitator wings includes flat oval surfaces as seen in their plane of rotation tapering toward their distal ends, in each of which a recess is formed that penetrates the agitator wing, and wherein sides of the agitator wing facing away from each other in a forward area with respect to the rotation direction are inclined with regard to the plane of the other agitator wing, and include reduced material thickness toward the outer edge, and wherein sides of the winged agitator facing each other in the rearward area of the recess with respect to the rotation direction are inclined with regard to the plane of the other agitator wing, and include reduced material thickness toward the outer edge.
