Screw Flights - Bulknet

Typically both the hollow centre pipe and the hollow flight are used as a heat exchanger to cool, heat or thaw the material being conveyed. Short pitch screws are used in inclined conveyors. They are also used to control the feed at the inlet and to reduce flushing of free flowing materials. The shorter the pitch the more efficient is the

HEAT-TRANSFERRING, HOLLOW-FLIGHT SCREW

02.09.2009· Steam-heated, hollow-flight screw conveyors are commonly used to convey and transfer heat to a material. Common applications for such screw conveyors include cooking, heating, and drying of solid and semi-solid materials. In general, these screw conveyors have a helical flight that conveys the material as the screw conveyor is rotated.

Screw Heat Exchanger – Koellemann

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 and optionally
