[0024] See also Figure 1-4 A down drying and sterilizing device comprises a drying cylinder 1, wherein the drying cylinder 1 is provided with a feed inlet 11 and a discharge outlet 12, wherein a rotator is rotatably connected in the drying cylinder 1, wherein both ends of the drying cylinder 1 are fixedly connected to a hot air duct 3, wherein each of the hot air ducts 3 is provided with a plurality of air guide plates 31, wherein the adjacent air guide plates 31 and the ventilation duct form a hot air channel 32, and further comprising a plurality of air shields 33 arranged in the adjacent air guide plates 31, wherein each of the air shields 33 is arranged at intervals in the hot air ducts 3 on both sides, and wherein an opening and closing component for opening and closing the discharge outlet 12 is arranged at the bottom of the drying cylinder 1. The hot air duct 3 is connected to a hot air blower, and the hot air blower transmits hot air to the two hot air ducts 3 at intervals.
[0025] The down enters the drying drum 1 from the feed port 11 and rotates with the rotator. The hot air enters the drying drum 1 from the hot air channel 32. Due to the wind shields 33 arranged at intervals on both sides, the down in the drying drum 1 moves back and forth in the length direction of the drying drum 1 under the action of the interval hot air, thereby completing the full drying and sterilization of the down.
[0026] Furthermore, the rotator includes a rotating shaft 21, on which a plurality of partition plates 22 are arranged, and brackets 23 rotatably connected to the rotating shaft 21 are fixedly arranged at both ends of the drying cylinder 1, and one end of the rotating shaft 21 passes through the hot air duct 3 and is connected to the motor 24. The motor 24 is arranged on the peripheral fixed facilities; the down enters the drying cylinder 1 from the feed port 11, and the motor 24 drives the rotating shaft 21 and the partition plates 22 to rotate, and the down rotates synchronously with the partition plates 22, thereby cooperating with the hot air channel 32 to perform drying and sterilization.
[0027] Furthermore, a scraper 25 is fixedly connected to the side wall of the air guide plate 31, and the scraper 25 abuts against the inner wall of the drying cylinder 1 to prevent the down from adhering to the inner wall of the drying cylinder 1.
