[0029] Specifically, after the crop seeds are fed from the feed port 101, they are tumbled by the rotation of the drum 100, and are simultaneously transported to the discharge port 102 by the propulsion of the spiral blades 110. During the propulsion, the seeds are prevented from piling up due to the action of the arc surface 111, and the seeds can also tumble on the arc surface 111. When the seeds are tumbling and transported, the hot air ejected from the equally spaced hot air nozzles 220 covers the surface of the seeds and takes away the moisture in the seeds, and the airflow blown from the air nozzle 210 can remove the water-carrying air. Therefore, in the drying process of this embodiment, the hot air at an appropriate temperature can efficiently dry the seeds and avoid the situation where the seeds are inactivated by high temperature.

[0030] In one embodiment of the present application, Figures 1 to 5 As shown, preferably, an anti-skid layer is applied on the inner wall of the drum 100 and the arc surface 111 to increase the friction force on the crop seeds, so that the crop seeds roll longer and the drying efficiency is improved.
