PCT No. PCT/EP83/00055 Sec. 371 Date Oct. 6, 1983 Sec. 102(e) Date Oct. 6, 1983 PCT Filed Feb. 26, 1983 PCT Pub. No. WO83/03052 PCT Pub. Date Sep. 15, 1983.A device for coating formed bodies, like dragees, has a device for spraying the formed the formed bodies with a drageeing suspension and a suction device for sucking off air and dust while the formed bodies are in a kettle and moved therein by rotation of the kettle about a titled axis so that the drageeing material undergoes a three-dimensional rolling movement. The suction device has one or more perforated separating walls so in the kettle that, during the rotation of the kettle, running off drageeing material flows over a portion of one side thereof and air removal from the other side of the separating walls is restricted thereto. As a result, a large part of the air flows through the running off material for more effective drying and dust removal.
