The invention relates to a steam drying device of a continuous pigment dyeing padding mangle, which comprises steam drying cylinders, drying transmission mechanisms, a second humidity-discharging device, a water ratio detecting device and an electric cabinet which are arranged on a second mangle frame, wherein the steam drying cylinders are divided into two groups; and the drying transmission mechanisms are divided into two groups correspondingly. During operation, the drying transmission mechanisms drive a fabric to advances sequentially to be dried on the steam drying cylinders. If the water ratio detecting device detects that a water ratio is overhigh, the electric cabinet can be operated in an automatic or a manual mode to reduce the rotating speed of a transmission motor to increase drying time; and otherwise, the rotating speed of the transmission motor is increased to reduce the drying time. Because two groups of steam drying cylinders are adopted to achieve a high advancing speed of the fabric, the steam drying device of the continuous pigment dyeing padding mangle improves the drying efficiency and has a high processing capacity of the drying fabric.
