The present invention relates to a roller cooling device for the continuous conversion of a hot flowable mass into solid chips by cooling, with at least one cooling roller, one crushing roller and one pressing belt, rotating via deflecting pulleys. The cooling roller and crushing roller serve for rolling out the mass into a thin film. The pressing belt runs on a part circumference of the cooling roller and serve for pressing the film against the cooling roller there. The parts are held from only one side and the rollers are mounted only on the same side and are driven from the same side, and in that said the parts are thereby accessible and/or demountable from the other side for cleaning purposes.
