Device for the continuous coating of cores with a draining device, which is composed of at least one drum (91) rotatably driven, in which a product (5) is coated with one or several masses of coating or subjected to other treatment processes, such as spraying, drying and the like, in which the interior space of the drum (91) is subdivided into a multiplicity of chambers (72-74) isolated from each other, in which the longitudinal conveyor it can be temporarily switched from transport operation to mixing operation, so that if necessary a passage from one chamber (72-74) to the other chamber (72-74) adjacent with a product transport is formed, in which the chamber (72-74) is formed respectively by the drum wrapper (66) and by two discs (68-71) spaced apart from one another, connected in a integral manner in rotation with the drum wrapper (66), which respectively have a an opening that can be closed and opened by means of a closing element (76) operable by means of a drive (78), characterized in that at least one pivoting cover (68-71) is arranged as a closing element (76) on the separator disk (68-71). 76), whose pivot axis (77) is oriented almost perpendicularly to the plane of the drum wrap (66), whose pivotable free end can be applied to the adjacent separator disk (68-71), whereby the pivoting cover ( 76) acts as a diverting cover and longitudinal conveyor of the product (5) through the opening.Dispositivo para el revestimiento continuo de núcleos con un dispositivo de drageado, que se compone de al menos un tambor (91) accionado de forma giratoria, en el que un producto (5) se reviste con una o varias masas de recubrimiento o se somete a otros procesos de tratamiento, como por ejemplo, pulverización, secado y similares, en el que el espacio interior del tambor (91) está subdividido en una multiplicidad de cámaras (72-74) asiladas unas respecto a otras, en el que el transportador longitudinal se puede conmutar temporalmente del funcionamiento de transporte al funci
