[0030] When the corrugated paper needs to be dried, the corrugated paper can be placed on the supporting platform 11, and the corrugated paper can be passed between the drag reducing roller 2 and the rotating disk 10, and then the air intake fan 19 is started. Through the rotation of the air intake fan 19, the air is filtered through the filter cover 18 and drawn into the interior of the air intake pipe 16, and then the air is heated by the heating plate 17.

[0035] A heat recovery condensation structure is disposed outside the box body 1, and the hot air heated by the heating plate 17 after drying the corrugated paper is recovered and reused through the heat recovery condensation structure.

[0036] As the corrugated paper is dried, the hot air will float upwards and be drawn into the return air port 14 by the suction fan 13, and then discharged through the heat dissipation return air duct 15 and the air outlet condensation pipe port 21, and heated again by the heating plate 17, and the hot air is recycled.

[0038] As the hot air enters the interior of the heat dissipation return air duct 15, the cold air drawn in by the air inlet fan 19 will pass through the heat dissipation return air duct 15 and the air outlet condensation pipe port 21, so that the water vapor contained in the hot air condenses on the inner walls of the heat dissipation return air duct 15 and the air outlet condensation pipe port 21, and falls into the lower end of the heat dissipation return air duct 15.
