steam-drying

from The Century Dictionary.

• noun The use of steam-driers to remove moisture from objects.
• noun The elimination from steam-vapor of any moisture in the form of water or mist. For every pressure and temperature steam which is called ‘dry’ is in equilibrium of tendency to condense back to water and to vaporize any water accidentally present. If the temperature rises such water will become steam and the vapor become drier. If the temperature falls some steam will go back to water, but the steam remaining uncondensed is dry as before. Further effort to dry results in superheating.
