ABSTRACT:
In the drying apparatus for rotary printing press for drying the ink on the printed paper which has a direct fired deodorizing apparatus (8) and a heat recovery apparatus (9) for heating the hot air circulating in a drying apparatus (1) by using the exhaust gas from the deodorizing apparatus, the drying apparatus and its control device are so adapted that a bypass line (20) is installed on the hot air circulation line to bypass the heat recovery apparatus to control the temperature of printed paper and/or the temperature of hot air blowing from nozzles (3) by adjusting the degree of opening of a bypass damper (21) disposed in the bypass line, and the burning amount of the burner for deodorization is controlled so that the deodorizing apparatus furnace temperature corresponding to the blowing hot air temperature (16) or paper temperature (17) is obtained. Further, the control device carries out the control in response to the change in printing speed. Thus, the control responsiveness can be enhanced.
