[0025] The overall working principle: during the drying operation, the resin is introduced into the interior of the drying cylinder 8, and then the power of the heating plate 9 is turned on to heat the interior of the drying cylinder 8. Then, the rotating mechanism 7 is used to control the rotation of the drying cylinder 8 to stir the raw materials. At the same time, the fan 13 is started to circulate the hot air inside the drying cylinder 8 in the circulation bin 4 and the interior of the drying cylinder 8. The steam carried in the hot air will gather at the top of the circulation bin 4. The steam removal machine 14 can remove the steam generated by drying to speed up the drying. In addition, when the circulating hot air enters the interior of the drying cylinder 8 through the sleeve 5, it is evenly discharged through the pores 6 and blown on the surface of the raw materials. Therefore, direct contact drying and hot air drying are adopted in the drying process of the resin to speed up the drying rate.

[0026] In this embodiment, a filter screen 11 is disposed inside the through pipe 10 , and a side surface of the filter screen 11 is flush with an end surface of the through pipe 10 .

[0027] Partial working principle: In the process of controlling the hot air circulation, the filter 11 is used to prevent the raw materials from entering the inside of the circulation pipe 12.
