steam-drier

from The Century Dictionary.

• noun An apparatus or plant for removing moisture from lumber, cloth, air, etc., by heat conveyed from a boiler to coils of pipe. A circulation of air, either natural or forced by a fan, carries away the moisture vaporized out of the material by the heat. To raise the temperature of air is to increase its capacity to carry moisture without tendency to precipitate it, and this principle is made use of in the steam-driers to cause the air to absorb moisture from other objects.
