Abstract: The invention provides a method and apparatus for energy efficient drying of moist material, for example washed garments, using superheated steam as the drying medium. Apparatus for carrying out the method comprises a casing 10 which is thermally insulated and gas-tight apart from an outlet vent 11. The air initially within the casing is circulated by a fan 13 through a heat source 16 and through moist garments 17. The heated air produces steam from the moisture in the garments which, due to the resultant increase in pressure in the casing, eventually displaces the air from the casing. Continued recirculation of the steam through the heat source 16 causes it to become superheated. As the process continues, and more moisture is evaporated from the garments, a portion of the superheated steam is continually discharged through the vent 11 where it passes into a condenser where its thermal energy is recovered and is transferred by heat exchange to, for example, water which may be used for other purposes.
