ABSTRACT:
A laundry ironing system, comprising a pre-drying cylinder and at least one mangle cylinder and trough unit, in which a flowable heat carrier medium in the form of live steam that circulates through the mangle cylinder and trough unit and then through the pre-drying cylinder is depressurized within the pre-drying cylinder to generate flash steam which precipitates on the internal surface of the pre-drying cylinder when condensing, thus heating the pre-drying cylinder. The present invention is also directed to such a method of heating the pre-drying cylinder, by collecting the flowable heat carrier medium in the form of live steam, and directing the medium inside the pre-drying cylinder where the heat carrier medium is depressurized, resulting in the formation of flash steam precipitating on the internal surface of the pre-drying cylinder. The heat carrier medium is then withdrawn from the pre-drying cylinder.
