PURPOSE: A conveyor-type drying system having an air injection device is provided to improve drying efficiency, remove a restriction in installation space by shortening the length of the system, and reduce the manufacturing cost and the installation cost. CONSTITUTION: A conveyor-type drying system having an air injection device comprises plural far infrared lamps(35) installed at regular intervals in the longitudinal direction of a drying chamber(11); a preheating air injection pipe(59) disposed alternately with the far infrared lamps between the far infrared lamps and a conveyor(20) transferring objects(80); an air chamber(43) installed to the inside of the drying chamber and connected to a blowing fan(52) and a preheating air injection duct(47) by an air hose(49); a preheating heater(45) made of heater pipes having a hot wire inside and installed in the air chamber; and a blowing unit(44) comprising the blowing fan installed to the outside of a body and an air filter(51) installed to the suction port side of the blowing fan, to filter foreign materials contained in external air. A blowing port of the blowing fan is connected to the air chamber by the air hose.
