PURPOSE: A strip dryer is provided to transfer the air injected from an injection nozzle to both sides of a strip by arranging an injection pipe on the strip in V shaped pattern. CONSTITUTION: A strip dryer comprises an injection pipe(100), multiple injection nozzles(120), a supply tank(200), a feeding line(300), a detection sensor, and a control unit. The injection pipe is arranged to be bent sharply the longitudinal direction of a strip. The injection nozzle is arranged to be separated along the longitudinal direction of the injection pipe, and sprays the air to both sides of the strip. The supply tank supplies the air to multiple the injection nozzles. The feeding line connects the injection pipe and the supply tank. The injection pipe includes the main injection pipe with a bent portion(110) arranged at the central part, and a first sub-injection pipe with bent portions arranged both sides of the main injection pope, and a second sub-injection with a bent portion arranged on both sides of the first sub-injection pipe. The control unit controls the range of the air injection through the injection nozzle based on the width of a strip detected by a sensor.
