The invention discloses a radiograph drying machine. The machine includes a drying machine shell, a machine door, radiograph hanging rods and a temperature control hot-air machine, wherein one side of the drying machine shell is provided with the machine door, and the top of the drying machine shell is provided with a cross plate through a connecting rod; the bottom of the cross plate is provided with the multiple radiograph hanging rods, and the two opposite sides of the interior of the drying machine shell are provided with side guide rails. According to the radiograph drying machine, through the arrangement of the temperature control hot-air machine, temperature control drying can be conducted on radiographs inside the drying machine shell so as to avoid that radiograph developing is vague since the temperature is higher than 55 DEG C, which effectively improves the drying quality of the drying machine to the radiographs; moreover, the temperature control hot-air machine can move in the drying machine; on the one hand, the drying efficiency of the radiographs is improved, the drying cost of the radiographs is reduced, and the caused pollution to the radiographs when the radiographs are dried is prevented; on the other hand, the radiograph drying uniformity of the drying machine is improved, and it is avoided that uneven drying caused by heating source fixing influences developing.
