A cleaning device for a residue contaminated conveyor belt includes a roller arranged below the conveyor belt such that the lateral surface thereof contacts a lower strand of the conveyor belt, and a cleaning belt is arranged below the roller. The lateral surface of the roller contacts an upper strand of the cleaning belt, which is tilted relative to a main conveying direction at the upper strand relative to a longitudinal roller axis. A dispensing device on and/or above the cleaning belt feeds a solvent thereon. The dispensing device and the cleaning belt are relatively arranged such that the solvent from the cleaning belt is conveyed by a conveying movement of the cleaning belt into a region in which the cleaning belt contacts the roller, which via a rotational movement, at least partially picks up the solvent located on the cleaning belt and dispenses it onto the conveyor belt.
