    Dry kilns can reduce the moisture content to 5-6%, and the hotter ones can dry most kinds of wood at the fastest possible rates. They do not need vents, but vents can be used for closer temperature control. A pre-dryer can be used to reduce the moisture content to approximately 25% before a dehumidification kiln is used
