The invention relates to a device for the coating of granulates and seeds, pellets and dragees with one or several coatings, whereby the seeds for coating are placed in a driven rotating drum, into which baffles fixed to the housing, in particular, spray and cleaning arms extend. Air supplies are connected to the drum, by means of which the interior of the drum is subjected to an air stream. The air distribution in the drum is achieved by means of an air splitter-plate fixed to the front side of the drum, arranged opposite a non-rotating air splitter plate fixed to the housing, which is formed such that it may move in an axial direction towards and away from the drum and which may be connected to the drum by means of air. An improved cleaning of the housing and drumward air feed is thus guaranteed.
Device for coating granulates and seeds, pellets and dragees with one or more coatings, where the seeds to be coated are placed in a driven rotating drum, into which baffles fixed to the housing, especially spray and cleaning arms extend, where air supplies are connected to the drum by means of which the interior of the drum is subjected to an air stream, characterized in that the air distribution in the drum (2) is achieved by means of an air distribution plate (11) fixed to the front side of the drum associated with an opposite non-rotating air distribution plate (10) fixed to the housing which is configured such that it can move in axial direction towards and away from the drum (2) and which can be connected with the drum (2) by means of air.
Device for coating granulates and seeds, pellets and dragees with one or more coatings, where the seeds to be coated are placed in a driven rotating drum, into which baffles fixed to the housing, especially spray and cleaning arms extend, where air supplies are connected to the drum by means of which the interior of the drum is subjected to an air stream, characterized in that each air-carrying duct (31) in the drum is covered in radial outward direction by an air duct cover (20) configured such that it can move in radial direction towards and away from the drum.
