Abstract:
A device for producing a pourable product, comprising a rotor chamber (1) having an axially extending cylindrical wall (6), a rotor (4) defining a vertical rotor axis (3) mounted within said rotor chamber, said rotor (4) having a central horizontal surface and, at least in its radially outer third, the shape of a conical shell (22) with an outward and upward inclination on the rotor axis (3) of between 10Â° and 80Â°, said conical shell having an upper edge (5) of circular shape and lying in a plane (9) perpendicular to the rotor axis, feeds (13, 14, 15) for introducing starting materials for the pourable product, a plurality of guide vanes (11) for circulating the starting materials or the product, said guide vanes (11) being affixed statically on said wall (6) within said rotor chamber (1) and located above the plane (9) of the upper edge (5) of the conical shell of the rotor (4) and having, in cross section to the rotor axis (3), essentially the shape of a segment of a circle or spiral, the outer ends of said guide vanes emerge tangentially from the cylindrical wall (6) of the rotor (4); and the inner ends of said guide vanes lie approximately midway of the rotor radius such that circulating product, which leaves the rotor (4) under the influence of kinetic energy, rolls on an inside surface of said guide vane (11) and falls back into the rotor (4).
