Abstract (en)
[origin: EP0486912A2] To minimise the entrainment losses, the treatment solutions are automatically removed from the immersion drum by means of a drainage channel (DK) and a drip strip (15) after the drums (1) have been lifted out of the treatment baths (13). When the drum (1) is rotated in the direction of rotation (B) by means of the drum rotary drive (16), a barrier strip (2) and a drainage strip (3) prevent the product conglomerate and the treatment solution dropping onto the inside casing of the drum (1). The treatment solution collected in front of the drainage channel (DK) drains via the openings (6) in the drum casing (4). A control system controls the sequence of transport, rotation and direction of rotation of the drum (1), and also the stop and go operation for the rotation of the drum (1) in order to optimise the separation phase for removing treatment solutions from the drum (1). <IMAGE>
