Abstract

The system to remove water, or other condensation, from a steam-heated drum used in paper manufacture, uses an internal spiral configuration to give a number of water collection zones across the width of the drum. The system ensures that the water content of the drum is kept in small-volume zones which are easily extracted, which reduce the weight and the drive power required, and which can be contained without being deflected by the centrifugal forces of the drum rotation.
