Abstract: The disclosure relates to a processing system for in particular pharmaceutical powders, and to a method for decontamination of such a processing system. The processing system includes a processing device for the powder, and a closed housing with an inner production space in which the processing device is arranged. The processing system further includes a steam generator via which water vapor is introduced into the production space in such a quantity that air supersaturated with water vapor develops there at least in some parts. Any powder residues present are bound via water since, on account of the supersaturation, water condenses in the production space. The condensed water, including powder residues bound therein, is removed, in particular with the housing opened.

Abstract: The application relates to a processing system and to a method for processing pharmaceutical powders. The processing apparatus comprises a plurality of processing stations which are arranged in a cyclical manner. The processing system includes at least one first zone and one second zone, wherein each zone includes at least one processing station of the processing apparatus. A cleaning tunnel which encompasses at least one processing station of the second zone is included in the second zone. A first end of the cleaning tunnel adjoins the first zone. A suction installation is arranged in the region of an opposite second end of the cleaning tunnel. Using the suction installation, a purifying-gas stream is generated in the cleaning tunnel.
