Abstract

The shrouding for the contact drying cylinder, to dry fabric piece goods, has a dividing wall to give a convection heat transfer to the drying gas to the fabric through radiation from heaters connected to an external power supply. - Pref. the dividing wall has a large number of channels through the wall in the direction of cylinder surface rotation, spaced from each other and connected to an external steam supply. The channels act to intensify the drying gas and deflect it into the flanges extending round the direction of cylinder surface travel. The channels are linked to the external steam supply through a lateral steam distribution channel connected at its lower end to a lateral condensation removal channel. The condensation removal channel. The condensation removal channel leads to the ends of the shrouding, with openings in the dividing wall, to give a locally intensified drying gas flow from the outer to the inner flow channel. Two dividing walls can be fitted, in the direction of cylinder surface travel, with separate drying gas entry openings and a common outlet opening for the moisture-laden drying gas.
