Abstract: Disclosed is a method for continuously coating cores by means of a dragée-making apparatus (15) comprising at least one rotatably driven drum (1) in which the product (5) is coated with one or several coating materials or is subjected to other treatment processes, such as spraying, drying. In order to be able to individually treat several small charges within a very limited space and with little effort regarding machines, the charge of the product that is to be processed is divided into small individual charges at the inlet end of the drum, is conveyed through the drum in a clocked manner, and is treated in individual treatment chambers (7, 8, 9, 10, 11, 12, 13) in the drum, which are separated from each other. The longitudinal conveyor (3) that conveys the individual charges through the drum embodies the individual treatment chambers in connection with the inner wall of the drum.

Abstract: Continuously coating cores by a dragee-making apparatus including at least one rotatably driven drum in which the product is coated with one or several coating materials or is subjected to other treatment processes. The charge of the product to be processed divided into small individual charges at the inlet end of the drum is conveyed through the drum in a clocked manner and treated in individual treatment chambers separated from each other. The longitudinal conveyor that conveys the individual charges through the drum embodies the individual treatment chambers in connection with the inner wall of the drum. The products to be treated constantly rotate in the revolving drum without being conveyed in the longitudinal direction, the longitudinal conveyor located in the drum conveying the product from one treatment station to the next as required. A passage is formed from one chamber to the adjacent, other chamber if necessary.

Abstract: A method for carrying out a cleaning process in coating systems. Such a coating system comprises a horizontally, rotationally mounted drum container for receiving the product which is to be coated and polygonal and perforated lateral areas which are sealingly covered, respectively, by an air duct. The invention also relates to a device for carrying out the method. The invention is characterised in that a cleaning lance, which can be displaced axially, automatically passes through the air duct arranged on the outer wall of the drum container for cleaning and/or drying, and it cleans and/or dries the inner wall of the air duct.

Abstract: A device for the coating of granulates and seeds, pellets and dragées with one or several coatings, whereby the seeds for coating are placed in a driven rotating drum, into which baffles fixed to the housing, in particular, spray and cleaning arms extend. Air supplies are connected to the drum by means of which the interior of the drum is subjected to an air stream. The air distribution in the drum is achieved by means of an air distribution plate fixed to the front side of the drum arranged opposite a non-rotating air distribution plate fixed to the housing, which is formed such that it may move in an axial direction towards and away from the drum and which may be connected to the drum by means of air. An improved cleaning of the housing and drum air feed is thus guaranteed.

Abstract: Spray arm for a coating device and a method of supplying a coating material to a spray arm. The spray arm including at least one nozzle pipe having an open end, a closed end, and at least one nozzle positioned between the open end and the closed end, and at least one delivery pipe having a supply end and a delivery end. The delivery end may be positioned adjacent the closed end of the at least one nozzle pipe, the open end of the at least one nozzle pipe may be couplable to a coating material supply, and the supply end of the at least one delivery pipe may be couplable to the coating material supply. The method includes supplying coating material to the at least one nozzle in a first direction substantially along a longitudinal axis of the at least one nozzle pipe, and supplying coating material to the at least one nozzle in a second direction, the second direction being substantially opposite the first direction.
