Abstract

Process and device for the treatment of lumpy products using process media, the treatment including a predetermined sequence of process steps. A chain of treatment units is moved in a stepwise manner. The product to be treated remains within the same treatment unit for the duration of the sequence of the process steps. A supply unit supplies and removes process media in a stopping-station specific manner so that the process steps can proceed simultaneously in the treatment units.
