A drying chamber through which the printing paper passes is provided with a nozzle for blowing hot air for drying the printing paper, and the hot air for drying the printing paper is heated through a heating device and a blower and is again supplied to the nozzle. In a dryer that has a path to purify a portion of the hot air that has dried the printing paper through a heating device and an oxidation catalyst and a blower to release it to the atmosphere, the hot air circulation path The heat exchange passage of the exchanger is interposed, the heat dissipation passage of the above heat exchanger is interposed in the passage of high temperature air for purification of the purification passage, and the cleaning passage is heated during high temperature drying to dry the printing paper printed with high temperature dry printing ink. The device and the heating device of the hot air circulation path are activated, and the heating device of the purification air path is activated and the heating device of the hot air circulation path is not activated during low temperature drying in which the printing paper printed with low-temperature dry printing ink is dried. Printing characterized by Of the dryer.
