[0022] The net cylinder 17 facilitates draining of the raw materials while ventilating, reducing the water adhering to the raw materials and improving the drying efficiency. The rotation driving mechanism drives the rotation cage 18 and the net cylinder 17 to rotate, causing the raw materials to be rotated and tumbled inside the net cylinder 17 to ensure that the drying mechanism can thoroughly dry the raw materials. The drying mechanism blows hot air while the raw materials are being tumbled to achieve hot air drying of the raw materials. The drying outer shell 2 covers the circumferential sides of the rotation cage 18 and the net cylinder 17 to reduce the escape of hot air and improve the drying efficiency.

After drying is completed, the end of the net tube 17 connected to the feed hopper is higher than the end connected to the discharge bin 21, so that the dried raw materials enter the discharge bin 21 and are discharged from the discharge hopper 22.

[0027] Further, the rotary drive mechanism includes a rotary drive motor 12 and a gear transmission pair; the gear transmission pair includes a driving gear 13 and a driven gear 14; the rotary drive motor 12 is mounted on the top plate 16; the driving gear 13 is mounted on the output shaft of the rotary drive motor 12; a transmission hole is provided on the top plate 16; the driven gear 14 is rotatably mounted on the transmission hole and extends into the drying housing 2; the driven gear 14 is meshed with the driving gear 13; a driven gear ring 15 is coaxially mounted on the outer circumference of the rotary cage 18, and the driven gear ring 15 is meshed with the driven gear 14.

[0029] The hot air is blown out by the hot air blower 25, and the hot air passes through the flexible air duct 24 and the air outlet pipe 20 in turn and is blown out from the air outlet hole 11. During the rotation of the mesh drum 17, the hot air dries the raw material and is then discharged through the exhaust pipe 28 to achieve hot air drying.

[0030] Furthermore, the bottom surface of the drying shell 2 is configured to be a downwardly contracted funnel, and a water outlet pipe 3 is provided at the bottom of the funnel-shaped bottom surface of the drying shell 2. The water drained from the net cylinder 17 is discharged by the water outlet hopper and the water outlet pipe 3, thereby reducing the humidity in the drying shell 2 to a certain extent.
