ABSTRACT:
A drying apparatus with a deodorizing member for a printing machine including a hot blast nozzle for directing a hot blast against a web of printed material for drying the printed material. The deodorizing member includes a preheating chamber provided with a burner for preheating a collective process gas including a portion of a used process gas already used during the drying operation. A catalytic layer is provided for oxidizing the used process gas and is operatively connected to a fan for supplying the used process gas through the catalytic layer. A duct circuit is provided for dividing a treated process gas including a hot blast obtained by the treatment with the deodorizing member into two parts and discharging one portion of the two parts and sub-dividing the other portion into two parts and introducing one part thereof to an odor collective chamber connected to the preheating chamber and introducing the other part to a hot blast mixing chamber into which the other part of the foregoing used process gas is supplied. In addition, a hot blast circulating blower is provided for supplying a mixture process gas of the treated process gas and the used process gas in the foregoing hot blast mixing chamber to the hot blast nozzle.
