According to the hollow-flight principle, screw flights are hollow, so that they provide a path for a cooling or heating medium to flow through. This means that bulk materials that have to be thermally processed, can be cooled, heated or kept at a constant temperature. Screw conveyors with conventional design only allow the heating or cooling medium to flow through the housing

Heating Cooling for Screw Conveyors. Heat transfer is accomplished through contact with an external jacket (bolt-on or integral), and/or through the transfer auger itself. The material is heated or cooled while being tranferred down the length of the conveyor. In the case of a hollow flight auger, the flights themselves aid in heat transfer.
