The downward pressure will force the shaft 651 and the first side 657 of the plate 652 to closely press against the top surface of the washer body 679, and force the supporting member 661 to closely press against the top surface of the connection washer 677, and force the shaft 651. One end of the protruding protrusion 661 is tightly pressed against the top surface of the outer washer 676. Since the inner washer 675 and the outer washer 676 are respectively made of Teflon, it can effectively reduce the friction between the shaft 651 and the aforementioned two components, and can reduce the friction between the plate 652 and the inner washer 675 force. Furthermore, since the connection washer 677 is made of Teflon, and the supporting member 661 is a bearing that is in rolling contact with the connection washer 677, the friction between the two can be effectively reduced. Thereby, each of the receiving units 65 can be smoothly and simultaneously rotated during the rotation of the rotating shaft 61.

The aforementioned carrier plate 650 at the waiting position P1 after receiving the material 8 will rotate in the rotation direction R1 to move away from the waiting position P1, and the carrier plate 650 originally located at the waiting position P2 will then rotate to the waiting position P1 to continue receiving Item 8.

Referring to FIG. 11, FIG. 12, and FIG. 13, when the aforementioned carrier plate 650 at the waiting position P1 is rotated at an appropriate angle in the rotation direction R1 to the blanking position P2, the carrier plate 650 of the uppermost carrier assembly 63 is finished with the animal material. 8 Rotational movements. During the rotation of the carrier plate 650 with the animal material 8, the hot air in the chamber 34 will continuously dry the material 8 on the carrier plate 650. When the carrier plate 650 is at the blanking position P2, the first side 657 of the plate body 652 is separated from the top surface of the washer body 679. At this time, the downward pressure of the material 8 on the plate body 652 will force the carrier plate 650 to move downward. The turning direction R2 rotates around the transverse axis L2 defined by the shaft 651, and the material 8 will gradually slide down the bearing surface 654 during the turning process of the bearing plate 650. When the bearing plate 650 is rotated to the flip angle position, the material 8 moves away from the bearing surface 654 and falls down to the bearing plate 650 of the next layer of the bearing assembly 63 at the waiting position P1, so that the bearing plate 650 can drive Material 8 performs the next rotary motion.

It should be noted that in the process of the upper layer carrier assembly 650 of the carrier plate 650 tilting the material 8 down to the next layer carrier assembly 650 of the carrier layer 650, the material 8 will first move away from the upper carrier plate 8 and then Then it is dropped on the next layer of the carrier plate 650. In this process, the contact area of the hot air and the material 8 will be increased, so that the material 8 can be dried uniformly to improve the drying effect.

Referring to FIGS. 14 and 15, the bearing plate 650 at the turning angle position will continuously rotate in the rotation direction R1. When the back surface 655 of the plate 652 touches the pushing inclined plate 682, it will be blocked by the pushing inclined plate 682. An upwardly-directed component force continuously applied to the back surface 655 will cause the carrying plate 650 to gradually rotate about the transverse axis L2 in an upward turning direction R3 to gradually raise the first side 657 of the plate body 652 upward. When the first side 657 of the plate body 652 moves to a position abutting the top surface of the washer body 679, the carrier plate 650 returns to the bearing angle position shown in FIG. 10 and at the same time returns to the waiting position shown in FIG. 9. The material position enables the carrier plate 650 to continue to receive the next batch of material 8.

Referring to FIG. 1, FIG. 2, and FIG. 3, the operation mode of the receiving unit 65 of the remaining layers of the receiving assembly 63 in the chamber 34 is the same as that of the aforementioned receiving unit 65 of the uppermost receiving assembly 63. I will not repeat them here. When the load-bearing plate 650 of the bottom-level load-bearing assembly 63 dumps the material 8 downwards and is opened by operating the discharge controller 5, the material 8 can be controlled to be discharged downward through the discharge port 311 into the collection box 7. . The weight of the dried material 8 can be reduced, and the volume can be reduced, thereby reducing the cost of subsequent cleaning and handling.

To sum up, the drying device 30 of this embodiment can individually perform the rotation movement of the animal material 8 by one rotation and the action of dumping the material 8 downward by each carrier plate 650 of each layer of the bearing assembly 63. Thus, the feeding device 10 can continuously convey the material 8 into the chamber 34, and the drying device 30 can continuously dry and dry the material 8. This can improve the efficiency of the drying operation. Furthermore, the path of the material 8 moving in the chamber 34 and the time of staying in the chamber 34 can be increased, so that the material 8 can be surely dried, so the purpose of the present invention can be achieved.
