ABSTRACT:
The invention relates to a device for covering lumpy products, especially pills, pellets or tablets, with a coating material, comprising a rotatable drum, a device designed for feeding air into the drum, a device designed for releasing the air from the drum, including at least one releasing air channel provided with at least one air passage opening directed to the interior space of the drum, and further comprising a device designed for spraying the product located in the drum with a coating material. In order to provide a coating device which is easy to operate, especially easy to clean, and the stop periods of which are substantially reduced, the at least one releasing air channel extends along at least one part of the inside wall of the drum and is detachably connected thereto. Thus, the releasing air channels are easy to detach from the drum and may be cleaned outside therefrom.
