Abstract
A complex type dryer includes a rotational cylinder, a drying material, a hot air provider, a hot air chamber and a scraping unit. The drying material provider is disposed over the rotational cylinder and coats a drying material on a surface of the rotational cylinder. The hot air provider is connected to both sides of the rotational cylinder, and includes first and second hot air tubes. The first and second hot air tubes alternately provide a hot air into the rotational cylinder or alternately exhaust the hot air passing through the rotational cylinder. The hot air chamber is disposed along an outer surface of the rotational cylinder outside of the rotational cylinder. The scraping unit is disposed at a side of the rotational cylinder, and removes the drying material from the surface of the rotational cylinder after dried by the rotational cylinder and the hot air chamber.
