  • the device described with reference to FIGS. 1 to 4 works as follows: In interval operation, the device is filled through the inlet opening 13 with the medium to be treated to just below the centrifugal wheel 5. Thereupon the inlet opening 13 is closed and the centrifugal wheel 5 is set in rapid rotation by a drive unit (not shown) via the drive shaft 8. Due to the resulting in the radial channels 6 Negative pressure, the medium is sucked out of the inner chamber 1 via the suction nozzle 4 and, due to the centrifugal force, is thrown out of the outlet openings 7 of the radial channels 6 into the outer chamber 2. The medium returns from the outer chamber 2 through the passage openings 16 into the inner chamber 1. This process is maintained until the medium has reached the desired consistency.
