[0023] See also Figure 1-4 As shown, a device for uniformly drying kudzu root powder comprises a drying box 1, a feeding pipe 2 is connected through the top of the drying box 1, and a discharge port 3 is opened at the bottom of the outer side of the drying box 1, a drying chamber 4 and a collecting chamber 5 are respectively arranged at the upper and lower ends of the drying box 1, and a rotating mechanism for turning and drying the kudzu root powder is arranged inside the drying chamber 4, and the rotating mechanism comprises a hollow rotating rod 10 rotatably connected to the inner side walls on both sides of the drying chamber 4, and the two ends of the hollow rotating rod 10 extend to the outer sides of the drying box 1, and the interior of the drying chamber 4 and the hollow rotating rod 10 are located The outer surface of the drying box 1 is evenly spaced and arranged with through hollow flip plates 11. The first gear 15 is fixedly connected to the outer surface of one end of the hollow rotating rod 10 outside the drying box 1, and the end thereof is rotatably connected to a rotary joint 17. The middle of the outer side surface of the drying box 1 and located below the first gear 15 is rotatably connected to the second gear 16 through a connecting rod 18. A driving motor 9 is installed at one end of the connecting rod 18 corresponding to the outer side of the drying box 1. The output end of the driving motor 9 is fixedly connected to the connecting rod 18, and the first gear 15 and the second gear 16 are meshed. The kudzu root powder to be dried is transported to the drying chamber 4 in the drying box 1 through the feeding pipe 2. Then, the driving motor 9 is used as a driving source to drive the connecting rod 18 to drive the second gear 16 to rotate, and under the meshing characteristics of the gears, the first gear 15 is synchronously driven to rotate, so that the hollow rotating rod 10 drives the hollow flip plate 11 to continuously flip and stir the kudzu root powder, preventing the kudzu root powder from condensing into a block, ensuring the drying efficiency, and improving the uniformity of the kudzu root powder drying.

[0024] The outer wall of the drying box 1 is provided with a heating mechanism for heating the rotating end of the rotating mechanism, and the heating mechanism includes a hot air blower connected to the bottom of the outer side of the drying box 1, and the air outlet end of the hot air blower is respectively connected with a first air outlet pipe 12 and a second air outlet pipe 13, and the end of the first air outlet pipe 12 is connected to the rotating joint 17 on the end of the hollow rotating rod 10, and the end of the second air outlet pipe 13 passes through the top of the drying box 1 and extends to the inner top surface of the drying chamber 4. A valve 14 is fixedly installed on the outside of the drying box 1 and on the second air outlet pipe 13. By starting the hot air blower, the formed hot air is transported to the first air outlet 12 and the second air outlet 13 through the air outlet respectively, and then the hot air is sent into the hollow rotating rod 10 along the first air outlet 12, and is diverted to the hollow flip plate 11 along the hollow rotating rod 10, and is discharged along the end of the hollow rotating rod 10. The hot air is continuously heated, so that the temperature of the contact surface between the hollow rotating rod 10 and the hollow flip plate 11 and the kudzu root powder is continuously increased, thereby improving the drying processing efficiency. At the same time, after the material is unloaded, the valve 14 on the second air outlet 13 can be opened, and the hot air can be blown away and removed along the second air outlet 13 to the kudzu root powder blocks remaining in the drying chamber 4 and adhered to the inner wall, thereby avoiding waste and the trouble of cleaning in the later stage, and further improving the applicability of the device.

[0025] A through hole 6 connected to the collecting chamber 5 is provided on the inner bottom surface of the drying chamber 4, and a T-shaped baffle plate 7 is connected to the inner top surface of the collecting chamber 5 and below the through hole 6. Both ends of the T-shaped baffle plate 7 slide in the sliding grooves 8 provided on the inner side walls of the collecting chamber 5. The other end of the T-shaped baffle plate 7 extends to the outside of the drying box 1 and is installed with a push-pull plate. The inner bottom end of the collecting chamber 5 is inclined, and its inclined end corresponds to the discharge port 3. When it is necessary to discharge the material, the push-pull plate is pulled to drive the T-shaped baffle plate 7 to slide back and forth in the sliding groove 8, so that the T-shaped baffle plate 7 can open and block the through hole 6, and then the through hole 6 can be blocked and closed during processing to prevent the kudzu root powder from flowing out. After the processing is completed, the through hole 6 is opened to discharge the material. The operation is simple and convenient to use.

[0026] The working principle of the utility model is as follows: when the kudzu root powder is dried, the kudzu root powder is added into the drying box 1 through the feeding pipe 2, and a valve is arranged on the feeding pipe 2. After the kudzu root powder is added, the valve on the feeding pipe 2 is closed;

[0027] Then, the hot air blower is turned on, and the hot air generated by the hot air blower is discharged from the air outlet end and transported to the first air outlet pipe 12 and the second air outlet pipe 13. The hot air is transported to the hollow rotating rod 10 and the hollow flip plate 11 by the first air outlet pipe 12 for preheating, so that the hot air contacts with the kudzu root powder to achieve the drying process of the kudzu root powder. During the drying process, the valve 14 is in a closed state.

[0028] At the same time, the driving motor 9 is started to drive the connecting rod 18 to rotate, and under the meshing characteristics of the gears, the first gear 15 and the second gear 16 rotate synchronously, thereby driving the hollow rotating rod 10 to rotate with the hollow flip plate 11 in the drying chamber 4. Secondly, since the hot air in the first air outlet 12 is continuously heated, the kudzu root powder is continuously flipped and stirred on the hollow rotating rod 10 and the hollow flip plate 11, which can not only effectively prevent the kudzu root powder from condensing into lumps, but also ensure the drying efficiency. The hot air does not directly contact the kudzu root powder, thereby avoiding the kudzu root powder in the drying box 1 from splashing around during stirring, affecting the processing effect and causing waste, thereby improving the uniformity of the kudzu root powder drying effect. Secondly, the rotating joint 17 can ensure that the hollow rotating rod 10 can continue to rotate while the first air outlet 12 continuously outputs hot air.

[0029] After the kudzu root powder is dried, the T-shaped baffle plate 7 is pulled to allow the kudzu root powder to flow into the collecting chamber 5 along the through hole 6, and flow along the inclined inner bottom surface of the collecting chamber 5 to the discharge port 3 for discharge. After the unloading is completed, the valve 14 on the second air outlet pipe 13 can be opened to blow away the kudzu root powder blocks remaining in the drying chamber 4 and adhered to the inner wall with hot air along the second air outlet pipe 13, thereby avoiding waste and the trouble of cleaning in the later stage, and further improving the applicability of the device.

[0030] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
