  • Patent number: 11731157
    Abstract: A drum coater device (10) for coating tablets, comprising a mixing drum (18) which can be rotated about an axis of rotation (20) and which has an interior (24) for arranging a tablet batch to be coated, further comprising a spraying device for introducing a coating material into the interior, wherein the mixing drum has a hollow-cylindrical, perforated wall which delimits at least part of the interior of the mixing drum, wherein mixing elements for mixing the tablets of a tablet batch are arranged on the inner side, which faces the interior, of the wall, wherein pairs (36) of mixing elements (34a, 34b) form legs which are oriented with respect to one another in a V shape, wherein the distance between the legs of a pair widens from a central annular region, as seen along the axis of rotation, of the wall in the direction of lateral annular regions adjacent to the central annular region.

  • Publication number: 20090064926
    Abstract: The invention concerns a drum for coating or drying grained substrates (10), said drum comprising a horizontal or slightly inclined axis (1). The invention is characterized in that the casing (2) of the drum comprises slots (5) for allowing through gas, said slots being formed between parallel ridges (8), said ridges (8) arranged inside the casing (2) of the drum sloping relative to the axis (1) and to the horizontal, such that the grained substrates (10), during rotation of the drum, are moved outwards of the drum into the discharge outlet zone. The geometrical cross-section of the ridges (8) is of any particular shape.
