The air-drying device for a twin-screw extruder set provided by the utility model comprises a roller passing assembly and an air blowing assembly. The roller passing assembly comprises a plurality of rotatable passing rollers, each passing roller is provided with a plurality of annular grooves for supporting material strands, and the plurality of passing rollers are arranged in parallel and at intervals along the traveling direction of the material strands. The air blowing assembly is arranged between two passing rollers, and the air blowing assembly at least comprises a group of air knives symmetrically distributed on the upper and lower sides of the material strands, and each air knife is provided with a slit-type air outlet facing the upper surface or lower surface of the material strands. By arranging an air suction assembly and a vacuum pump, the air suction assembly is located behind the air blowing assembly and between two passing rollers. The air suction assembly comprises an air suction pipe located below the material strands and air suction grooves formed at the top of the air suction pipe and corresponding to the annular grooves one by one. The air suction port of the vacuum pump is communicated with the air suction grooves through the air suction pipe, and the air exhaust port is communicated with the air outlets through the air knives, so that the material strands on the passing rollers pass through the air outlets and the air suction grooves in turn, with good air-drying effect and high energy utilization rate.
