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. The products that are 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. Additionally, a passage is formed from one chamber to the adjacent, other chamber if necessary.
