A device for the discharge of insoluble constituents in a dissolving apparatus has two conveying worms (40) arranged in troughs (36) in the container floor (30). Rabble arms (68, 70) can be twisted in a reciprocating manner above the container floor in order to bring about the progressive, monitored collapse of arches (84, 94) which have formed above the conveying worms. <IMAGE>
