[0028] In this invention, when in use, a certain amount of rice seeds are first added to the feeding assembly. Then, the second motor 13, the screening assembly, and the second motor 13 are started. The second motor 13 can drive the screening assembly to rotate via the transmission shaft 17. At this time, the rice seeds inside the feeding assembly will enter the interior of the feeding shell 5 and be lifted from the bottom to the top by the lifting assembly. Then, they will enter the rotating screening assembly through the discharge pipe 4. The screening assembly can then dry the rice seeds inside the screening assembly.
