The stirring structure is composed of a stirring main shaft 11 and a number of evenly and equidistantly arranged stirring horizontal shafts 12, which can stir the wood fiber during the drying process, effectively prevent the fiber from agglomerating, and ensure the uniform heating and drying effect of the fiber. Each stirring horizontal shaft 12 is connected to the inside of the stirring main shaft 11, and a number of evenly and equidistantly arranged hot air holes 13 are opened on the outer wall. This design allows hot air to flow out of the stirring horizontal shaft 12 evenly, thereby improving the drying effect.
