Embodiment Construction

[0018] figure 1 A processing system for powders for pharmaceutical use according to the invention is shown in perspective view. The processing system comprises a processing device 1 for powder, which is here a capsule filling device, but can also be a tablet press or the like, only schematically sketched as a box. Furthermore, the processing system comprises a closed housing 2 which encloses an inner production space 3 and which is hermetically sealed from the external environment during operation. The processing device 1 is placed in this inner manufacturing space 3 so that no partial quantity of powder to be processed can reach the outside.

[0019] Operating the processing device 1 from the outside of the housing 2 is possible by means of a user interface 11 . The operation can be monitored visually through the window 13 , which is also equipped with a glove interface (handschuheingriff, sometimes referred to as a glove operator) 14 . Manual access via the glove engaging...

Abstract

The invention relates to a processing system for powder and a method for cleaning such processing system, in particular to the processing system for especially medicinal powder and a method for cleaning such processing system. The processing system comprises a processing device (1) for powder and a closed housing (2) with an inner production space (3) in which the processing device (1) is arranged. Furthermore, the processing system comprises a steam generator (4), by means of which steam is introduced into the production space (3) in an amount such that air supersaturated with respect to the steam occurs at least in some sections. Possible powder residues are combined by means of water in such a way that the supersaturated water condenses in the production space (3). Condensed water, including powder residues bound therein, is removed, in particular when the housing (2) is open.

Description

technical field [0001] The invention relates to a processing system for powders for pharmaceutical use and a method for cleaning such a processing system. Background technique [0002] High-potency powders are processed to some extent in the pharmaceutical industry by filling them, for example, into hard gelatin capsules or pressing them into tablets. Such highly effective powders can exert toxic effects in corresponding concentrations. When processing such powders it must therefore be ensured that the machine operator and the surrounding environment are not overloaded or at all endangered. [0003] According to the prior art, such powders are processed in isolated spaces. The corresponding processing device is arranged in a production space enclosed by the housing in a hermetically sealed manner. Such a casing is also called a containment. A further challenge is that closed housings can also be opened when required, when a closed housing processing system ensures reliab...
