To dry and unload a large amount of objects to be treated with less thermal energy, by providing a fixed shelf with a falling port and a pore at a drying cylinder in multiple stages, providing a rotator at each fixed shelf that is fixed to a rotary shaft being supported at the drying cylinder rotatably oppositely, and suspending a crushed body in the rotator.

A drying cylinder 1 is provided with a throwing port 2 of an object W1 to be treated, a hot wind supply port 3 for accepting hot wind for drying the object W1 to be treated, and a carrying conveyor 4 for sending out the object W to be treated. The object W1 to be treated being thrown from the throwing port 2 or an object W2 that has already been treated being directed toward a lower shelf are deposited on the fixed shelf 5 with a falling port and a pore for hot wind being provided in the drying cylinder 1 in a mulitilayer system. The object W1 to be treated or the object W2 that has already been treated fall onto the fixed shelf 5 that is lowered at the lower part of a falling port and at the same time is dried and treated via the pore. A rotator 6 that opposes the fixed shelf 5 is fixed to an erected rotary shaft 7 of the drying cylinder 1 and a crusher 8 is provided at the rotator 6.
