[0031] The following further describes the present utility model with reference to the accompanying drawings, but the protection scope of the present utility model is not limited to the following.

[0032] As Figures 1 to 3 shown, a material dryer includes an oven 1. Inside the oven 1, a partition board 11 is vertically installed for dividing the internal space of the oven 1 into two parts. On one side of the partition board 11, a water filtering component 2 is installed, and on the other side, a drying component 3 for drying traditional Chinese medicine pieces is installed. On the top of the drying component 3 on the oven 1, an exhaust pipe 12 is installed. The exhaust pipe 12 is communicated with the inside of the oven 1 for discharging waste gas. The water filtering component 2 includes a support frame 21 and a drum 22. The support frame 21 is inclined and installed inside the oven 1. The height of the support frame 21 at the end close to the partition board 11 is lower than that at the end far from the partition board 11. The drum 22 is rotatably installed on the top of the support frame 21 and is parallel to the support frame 21. A plurality of filter holes 23 are uniformly arranged along the circumferential direction of the drum 22. A first driving motor 24 is installed on the support frame 21. On the output shaft of the first driving motor 24, a transmission shaft 25 is coaxially installed. The transmission shaft 25 is rotatably installed on the support frame 21, and the length direction of the transmission shaft 25 is the same as the length direction of the drum 22. Two transmission wheels 26 are sleeved on the transmission shaft 25. The two transmission wheels 26 are respectively rotatably connected to the two ends of the drum 22. The transmission wheels 26 are used to drive the drum 22 to rotate. The discharge end of the drum 22 is communicated with the other side of the partition board 11. A hopper is installed on the oven 1, and the hopper is communicated with the feed end of the drum 22. The bottom of the oven 1 is installed with a discharge hopper 14. The discharge hopper 14 is located below the drying component 3 for outputting the dried traditional Chinese medicine pieces.

[0033] The traditional Chinese medicine decoction pieces enter the drum 22 from the hopper. Start the first driving motor 24. The first driving motor 24 drives the transmission shaft 25 to rotate. During the rotation of the transmission shaft 25, it will drive the transmission wheel 26 to rotate. During the rotation of the transmission wheel 26, it will drive the drum 22 to rotate. During the process of the traditional Chinese medicine decoction pieces rolling on the drum 22, the water droplets can be thrown out through the leakage holes, so as to control the water on the surface of the traditional Chinese medicine decoction pieces. The effect of water control for throwing water is better, with high efficiency. The traditional Chinese medicine decoction pieces after water control are then dried by the drying component 3, which can improve the drying efficiency of the traditional Chinese medicine decoction pieces and has a better drying effect.

[0034] As Figures 1 to 3 shown, a spiral plate 27 is installed inside the drum 22; the spiral plate 27 can extend the distance of the traditional Chinese medicine decoction pieces from the feed end to the discharge end of the drum 22, thereby increasing the residence time of the traditional Chinese medicine decoction pieces on the drum 22, and further enabling the drum 22 to throw the water on the traditional Chinese medicine decoction pieces more cleanly.

[0035] As Figures 1 to 4 shown, the drying component 3 includes a plurality of conveyor belts 31 and electric hot air blowers 32. The plurality of conveyor belts 31 are all inclined towards the bottom of the drying oven 1, and the plurality of conveyor belts 31 are arranged in a staggered manner up and down. The plurality of conveyor belts 31 form an S-shaped drying channel. A discharge hopper 14 is provided at the bottom of the drying oven 1. One end of the discharge hopper 14 is located below the conveyor belt 31. A second driving motor 33 for driving the conveyor belt 31 to rotate is installed on the side wall of the drying oven 1. The electric hot air blower 32 is installed on one side of the drying oven 1. An air delivery pipe 34 is connected and installed on the electric hot air blower 32. The end of the air delivery pipe 34 away from the electric hot air blower 32 is connected to the bottom of the drying oven 1; the traditional Chinese medicine decoction pieces fall from the discharge end of the drum 22 onto the conveyor belt 31, and the traditional Chinese medicine decoction pieces will move towards the bottom of the drying oven 1 along the S-shaped drying channel formed by the plurality of conveyor belts 31. The hot air provided by the hot air blower dries the traditional Chinese medicine decoction pieces. Finally, the dried traditional Chinese medicine decoction pieces fall from the conveyor belt 31 at the bottom of the drying oven 1 into the discharge hopper 14, and then slide out of the drying oven 1 from the discharge hopper 14.

[0036] As Figure 1 、 Figure 2 shown, a plurality of air permeable holes 35 are formed in the conveyor belt 31, and the plurality of air permeable holes 35 are uniformly arranged along the length direction of the conveyor belt 31; the air permeable holes 35 can facilitate the flow of hot air, thereby improving the flow efficiency of hot air, and further improving the drying effect on the traditional Chinese medicine decoction pieces.

The tops of the multiple flexible baffles 7 are fixedly arranged, and the bottoms of the multiple flexible baffles are movably arranged. Since the bottoms of the flexible baffles 7 are movably arranged, the bottoms of the flexible baffles 7 can move towards the direction of the conveyor belt 31. The Chinese herbal medicine pieces can then fall onto the conveyor belt 31 through the gaps between the bottoms of the flexible baffles 7. Without affecting the falling of the Chinese herbal medicine pieces from the drum 22 onto the conveyor belt 31, the flexible baffles 7 can block the moisture thrown out by the drum 22 from entering the conveyor belt 31 to a certain extent, and the flexible baffles 7 can separate the areas on both sides of the partition plate 11 to a certain extent, thereby being able to slow down the air circulation between the hot air in the area where the drying assembly 3 is located and the area where the drum 22 is located, ensuring the dryness of the area where the drying assembly 3 is located, and further improving the drying effect on the Chinese herbal medicine pieces.

[0041] The implementation principle of this embodiment is as follows: When the staff needs to dry the Chinese herbal medicine pieces, the Chinese herbal medicine pieces are poured into the feed hopper, and then the first drive motor 24, the second drive motor 33, and the electric hot air blower 32 are started. The Chinese herbal medicine pieces are first further dried of the residual moisture on their surfaces at the drum 22, and then fall onto the conveyor belt 31. The conveyor belt 31 will carry the Chinese herbal medicine pieces and move slowly for drying. To improve the drying effect, the auxiliary heating wires 5 are started. The auxiliary heating wires 5 are located at the bottom of the Chinese herbal medicine pieces, thereby being able to accelerate the drying rate of the Chinese herbal medicine pieces. Finally, the dried Chinese herbal medicine pieces slide out of the oven 1 from the discharge hopper 14.

[0042] The above are only the preferred embodiments of the present utility model and do not impose any formal restrictions on the present utility model.
