    Dryer performance and the ability to transfer heat is dependent on the movement or behavior of the water within the dryer. At low speeds, condensate rests in a puddle at the bottom of the cylinder causing steam to condense on the inside wall. As speed increases, 'cascading' occurs as a layer of the condensate falls to the cylinder's bottom.
