Claim of US Patent No. 10,363,532

1. A module for a coating apparatus for granular bodies (1), the module comprising:a rotatable, hollow cylindrical drum (2) that is an accommodation unit for accommodating the granular bodies (1),
wherein within the drum (2) at least one moveable separating element (8) is disposed on an end side of the drum (2) such that transfer of the granular bodies (1) into the drum (2) and/or out of the drum (2) is achievable in a defined manner by a movement of the at least one moveable separating element (8);
wherein the at least one moveable separating element (8) is movable from a closed position to an open position, wherein, in the closed position, a closed subregion of an underside of the at least one moveable separating element (8) lies radially flush against an inner wall of the drum (2) or is arranged radially offset at a distance from the inner wall of the drum (2) via a gap measuring less than an external diameter of each of the granular bodies (1), and in the open position, the closed subregion on the underside is spaced apart from the inner wall of the drum (2) and, in this said open position of the at least one moveable separating element (8), there is an opening in the lower region between the underside of the respective at least one moveable separating element (8) and the inner wall of the drum (2), through which said opening the granular bodies (1) are arranged to pass, and
wherein the at least one moveable separating element (8) is configured to rotate about an axis of rotation (54) to bring the at least one moveable separating element (8) from the closed position into the open position, and the at least one moveable separating element (8) is configured so as to leave a clear space above the closed subregion, and on the end sides of the drum (2) there are elements (6, 7) to which a second drum (2) of at least one second module (3, 5) is connectable in order to form the coating apparatus, and/or to which a closure element (59) is connectable.
