PCT No. PCT/EP84/00109 Sec. 371 Date Dec. 20, 1984 Sec. 102(e) Date Dec. 20, 1984 PCT Filed Apr. 10, 1984 PCT Pub. No. WO84/04261 PCT Pub. Date Nov. 8, 1984.In a pivoted drum, e.g., a dragée coating drum for coating granular surfaces, a pivoted nozzle carrier (26b) projects along the drum axis, while forming an annular chamber (57), from which extends a multitude of similarly arranged elbows (64) with spray nozzles (65). A casing tube (22) surrounding the nozzle arrangement forms a lid (73) which, when in operating position, is opened by the spray nozzles, so that a spray can be sprayed into the coating chamber outside the casing tube (22). When in cleansing position (65'), the spraying device is completely sealed off to the outside and can be thoroughly rinsed with a cleansing agent which is drained off inside the casing tube (22) by the gutter (69) and the drain pipe (71). The cleansing processes can then be executed during the short intervals between coating, without interrupting the overall program.
