The steam-water separator 24 separates the water in the air.

[0027] In one embodiment, such as Figure 1 and Figure 3 As shown, a drainage assembly is installed at the bottom of the steam-water separator 24 to drain water.

[0028] In one embodiment, such as Figure 1 and Figure 3 As shown, the drainage assembly includes a water outlet pipe 25, which is installed at the bottom of the steam-water separator 24. A water storage tank 26 is installed on one side of the water outlet pipe 25, and a drain pipe 27 is installed on one side of the water storage tank 26.

Air is sent into the air outlet hopper 13 through the air outlet plate 3, and then divided by the partition plate 14. After that, the air is evenly distributed through the first flow equalization net 15, so that the circulating air is evenly sent into the heating lamp tube 16 to heat the air. This improves the energy efficiency of the device and the uniformity of material drying. The heated air is then evenly distributed through the second flow equalization net 17 and blown onto the material above the conveyor belt 1, improving the practicality of the device.
