[0002] In the prior art, by turning on the heating box, the rotating shaft drives the second fan blade to rotate when it rotates. At this time, the second fan blade draws the hot air in the heating box into the first gap, and then transports it to the surface of the medicinal materials, thereby effectively drying the medicinal materials. When the hot air flows in the first gap, the rotating shaft and the first fan blade are heated, thereby effectively improving the drying effect of the medicinal materials.

[0003] When the above-mentioned device is drying medicinal materials, hot air flows outward from the center of the gap. However, the medicinal materials in the middle will block the heat flow, causing the medicinal materials in the center to be heated more, while the medicinal materials near the edge have a smaller contact area with the hot air and are insufficiently heated, resulting in uneven drying of the medicinal materials. Therefore, a medicinal material drying device is needed. Utility Model Content

[0022] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0023] Medicinal materials refer to natural substances such as herbs, animals, and minerals used in traditional Chinese medicine theory and practice. According to the classification and application rules of traditional Chinese medicine theory, these substances are used for the purpose of preventing and treating diseases, regulating the balance of yin and yang in the human body, and promoting health. A medicinal material drying device is usually a device specifically designed to dry medicinal materials.

[0024] During the drying process of medicinal materials by the existing device, when hot air flows out from the central position of the gap, however, the medicinal materials in the middle will block the heat flow, resulting in more heat absorption by the medicinal materials in the central part, while the medicinal materials near the edge have insufficient heat absorption due to the smaller contact area with the hot air, resulting in uneven drying of the medicinal materials. Please refer to Figures 1-4 , the embodiment provides a medicinal material drying device, including a drying tank 1 and a feed pipe 11 and a discharge pipe 12 fixedly connected to the drying tank 1.

[0025] Refer to Figures 2-4As shown, during the drying process of medicinal materials by the existing device, when the hot air flows outwards from the central position of the gap, however, the medicinal materials in the middle will block the heat flow, resulting in more heat absorption of the medicinal materials in the central part, while the medicinal materials near the edge are insufficiently heated due to the smaller contact area with the hot air, leading to uneven drying of the medicinal materials. In order to improve the uniformity during the drying process of the medicinal materials and make the final drying effect meet the quality requirements, the following settings are made. A drying mechanism 2 for optimizing the hot air flow and uniformly drying the medicinal materials is provided on the peripheral surface of the drying tank 1. The drying mechanism 2 includes a hot air blower 21 fixed on the peripheral surface of the drying tank 1. The air outlet end of the hot air blower 21 is fixedly communicated with a gas converter 22. The bottom of the gas converter 22 is rotationally communicated with a spiral tube 23. A sliding sleeve is sleeved on the outer wall of the bottom end of the spiral tube 23 with a toggle cylinder 24. A sliding block is fixedly connected to the outer wall of the bottom end of the spiral tube 23. An activity groove communicating with the inside of the W-shaped gas transmission groove 25 is opened on the inner wall of the toggle cylinder 24. A sliding groove is opened on the inner wall of the activity groove. The sliding block slides up and down along the height direction of the sliding groove. A W-shaped gas transmission groove 25 communicating with the inside of the spiral tube 23 is opened on the inner wall of the toggle cylinder 24. A plurality of toggle blades 26 communicating with the inside of the W-shaped gas transmission groove 25 are fixedly connected to the peripheral surface of the toggle cylinder 24. A plurality of jet nozzles 27 are fixedly communicated with the peripheral surfaces of the plurality of toggle blades 26. An exhaust pipe 28 is fixedly communicated with the peripheral surface of the drying tank 1, which is used to release the water vapor generated during the drying process of the medicinal materials. Pour the medicinal materials into the drying tank 1 through the feed pipe 11 and start the hot air blower 21. The hot air flow enters the gas converter 22 and is sequentially transmitted through the spiral tube 23 - toggle cylinder 24 - W-shaped gas transmission groove 25 - toggle blades 26 until it is sprayed in all directions through the plurality of jet nozzles 27 on the outer wall of the toggle blades 26, which can make the hot air flow evenly cover the entire surface of the medicinal materials in the drying tank 1 without obstruction, improve the drying uniformity of the medicinal materials, and ensure that there will be no local overheating or over-wetting of the medicinal materials during the drying process, thereby maintaining the quality and medicinal efficacy of the medicinal materials.

[0026] Reference Figures 2-3As shown in the figure, a secondary drying mechanism 3 for driving the stirring blades 26 to rotate and vertically stir the medicinal materials in a small range for drying is provided at the top of the drying tank 1. The secondary drying mechanism 3 includes a motor 31 fixed to the top of the drying tank 1 and a belt 32 provided on the top of the motor 31. Pulley wheels are fixedly connected to the outer wall of the output end of the motor 31 and the outer wall of the top end of the rotary tube 23, respectively, and the pulley wheels are drivingly connected by the belt 32. A power rod 33 is fixedly connected to the outer wall of the top end of the stirring cylinder 24. A wavy rail groove 34 for the power rod 33 to slide is formed on the inner peripheral surface of the drying tank 1. A circular partition plate 35 is fixedly connected to the inner wall of the drying tank 1. The stirring cylinder 24 is slidably sleeved inside the circular partition plate 35, and the feed pipe 11 and the exhaust pipe 28 are both provided at the bottom of the circular partition plate 35. The circular partition plate 35 serves to block the medicinal materials to prevent the medicinal materials from entering the wavy rail groove 34 and affecting the operation of the secondary drying mechanism 3. During the drying process of the medicinal materials, the motor 31 is started. The output end of the motor 31 drives one of the pulley wheels to rotate. The rotation of one pulley wheel drives the other pulley wheel to rotate through the belt 32, driving the rotary tube 23 to rotate. The rotation of the rotary tube 23 drives the stirring cylinder 24 to rotate. The rotation of the stirring cylinder 24 causes several stirring blades 26 to rotate to stir the medicinal materials, which can make the hot air flow cover each part of the medicinal materials in the drying tank 1 more evenly, avoiding local drying or overheating caused by uneven hot air flow. While the stirring cylinder 24 rotates, the power rod 33 slides in the wavy rail groove 34. During the sliding process, the stirring cylinder 24 moves vertically in a small range reciprocally according to the track shape of the wavy rail groove 34, so as to realize the vertical up-and-down stirring of several stirring blades 26. After the medicinal materials are stirred and vertically stirred by several stirring blades 26, the hot air flow can transfer heat to each part of the medicinal materials more effectively. This uniform heat transfer helps to ensure the consistency and quality stability of the medicinal materials during the drying process. At the same time, it can effectively prevent the medicinal materials from caking or piling up due to their own weight or shape, which not only helps the uniform contact of the hot air flow, but also reduces the uneven drying problems that may occur during the drying process. At the same time, it can make the drying process more efficient, reduce the drying time, and ensure that the drying effect of each batch of medicinal materials can reach a consistent standard, thereby improving the overall production efficiency.

[0027] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
