Abstract (en)
An automatic interior cleaning system for a powdered material processing device cleans interior surfaces of powdered material processing devices such as silos, mixers, and dust collectors. A compressor and an accumulator tank (7) supply a cleaning gas, preferably air, at a sufficient pressure to dislodge residues of powdered materials that collect on interior surfaces of a powdered material processing device. A valve (6) connecting the accumulator tank (7) to a cleaning nozzle tube opens (4) and closes, supplying a pulse of air to the cleaning nozzle tube (4). Slits (5) in the cleaning nozzle tube (4) deliver the pulse of pressurized air to an inside surface of the powdered material processing device. The pulse of pressurized air produces a shock wave which dislodges residues from the interior surface of the powdered material processing device. Automatic removal of residues during processing prevents contamination of subsequently processed materials. <IMAGE>
