ABSTRACT:
A rotary drying drum for a moving web includes a stationary heater drum positioned coaxially within the drying drum such that the drying drum rotates around the heater drum. The heater drum may be supplied with steam via a hollow drying drum shaft without the use of high pressure steam joints. Heat from the interior heater drum is transferred to the rotary drying drum wall by a thin layer of suitable heat exchange fluid confined to the annular space between the coaxial drum walls. A low melting point bismuth/lead/tin alloy is the preferred heat exchange fluid.
