PROBLEM TO BE SOLVED: To reduce cost required for drying treatment by reducing the quantity of water used in a drying treatment machine. SOLUTION: The drying treatment machine has: a dryer for drying a treated material while agitating it by agitation blades disposed inside a treating container; a heating device for heating the inside of the dryer; a liquefying device for liquefying water vapor produced in the dryer; and a cooling water supply device for supplying cooling water to the liquefying device. The liquefying device is constituted to recycle water liquefied from water vapor, as cooling water of the cooling water supply device. The liquefying device has a dust separator at a part directly above the treating container of the dryer to separate dust in water vapor to fall into the treating container. The upper part of a cooling device for cooling water vapor, and the dust separator are connected in communication by a communicating pipe, and a filter is replaceably disposed at an intermediate part of the communicating pipe.
