Abstract (en)
[origin: WO2012032090A1] Stirrer (10) having a motor (12); a hollow shaft (14) that can be driven via the motor and is provided with at least one additive exit opening (16) via which an additive passed through the hollow shaft can be given off; and a rotor (22) that is arranged on the hollow shaft and has rotor blades (24), characterized in that a second rotor (26) having rotor blades (28) is provided on the hollow shaft, at a distance from the first rotor, and in that the at least one additive exit opening is arranged between the two rotors, wherein the rotors are constructed and can be driven in such a manner that during operation, a negative pressure and a centrifugal force are generated in the intermediate space (30) defined between the rotors.
