Maintaining uniform drying of the herbs is crucial during the production of prepared Chinese medicinal herbs, directly affecting their efficacy and quality. Traditional open-type drying ovens circulate hot air through fans, allowing the herbs to gradually dehydrate under natural convection conditions. However, existing equipment still has shortcomings in terms of airflow distribution and heat energy utilization.

[0003] Most common drying ovens currently use a fixed air blowing structure with a single airflow direction, which can easily lead to uneven heating of medicinal materials, resulting in localized overheating or insufficient drying. In addition, some drying ovens lack flexible airflow adjustment functions, making it difficult to adapt to the drying needs of different types of medicinal materials and affecting the overall processing effect.

[0036] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] like Figures 1 to 4 As shown, this utility model discloses a circulating open-type drying box for traditional Chinese medicine, including a drying box 10, a hot air supply mechanism 30, and an air delivery mechanism 40. During operation, the medicinal materials to be dried are placed in the drying box 10. The hot air supply mechanism 30 provides hot air, and the air delivery mechanism 40 delivers the hot air evenly to the medicinal materials, achieving uniform drying and improving the drying quality and efficiency of the medicinal materials.

[0038] Please see Figure 1 and Figure 2 The drying chamber 10 has an open-top drying cavity 11 on its inner side, forming an open structure that facilitates the handling and observation of medicinal materials, while also promoting natural moisture dissipation and improving drying efficiency. A detachable support net 20 is installed inside the drying cavity 11 to support the medicinal materials to be dried. Specifically, the inner wall of the drying cavity 11 has an annular groove 12 that extends circumferentially along the drying cavity 11 and matches the bottom edge of the support net 20. When the support net 20 is installed into the drying cavity 11, its bottom abuts against the groove 12, thus limiting the height of the support net 20. The support net 20 has evenly spaced ventilation holes 21 through which hot air passes. It should be noted that... Figures 1 to 4The ventilation holes 21 are enlarged for easier display; however, in the actual product, the diameter of the ventilation holes 21 is smaller than that of the medicinal materials to prevent them from falling through. Two symmetrically positioned handles 22 are also provided on the support net 20 to facilitate the removal of the support net 20 and the medicinal materials after drying, making it easy to handle. Additionally, a temperature sensor 13 is fixedly installed inside the drying chamber 10 to monitor the temperature of the drying chamber 11, ensuring a stable operating temperature so that staff can monitor and adjust the temperature according to the drying requirements of different medicinal materials.

[0039] Please see Figures 1 to 4 The hot air supply mechanism 30 includes a blower module 31 and a heating module 32 located on one side of the drying chamber 10 and interconnected. The blower module 31 blows air, which is then heated by the heating module 32 to produce hot air. The blower module 31 is a blower. The heating module 32 includes a cabinet 33 and several heating elements (not shown in the figure) installed inside the cabinet 33. The cabinet 33 includes an air inlet and an air outlet arranged opposite each other. There is one air inlet, which is connected to the blower. There are multiple air outlets, each of which is connected to a hot air distribution pipe 34, the other end of which is connected to the drying chamber 11. In addition, there are two sets of heating elements, arranged at the top and bottom of the inner side of the cabinet 33, respectively. The heating elements are connected to a control controller, which is connected to a temperature sensor 13. The control controller controls the voltage of the heating elements according to the monitoring results of the temperature sensor 13 to regulate the temperature of the hot air. A sealing ring 35 is provided at the connection between the hot air distribution pipe 34 and the drying box 10 to improve the sealing performance and prevent hot air from escaping and affecting the drying quality.

[0040] Please see Figures 1 to 4 The air supply mechanism 40 includes a drive module 41 and several air supply pipes 42. The air supply pipes 42 are equidistantly arranged and rotatably connected within the drying chamber 11, and are located at the bottom of the support net 20. Each air supply pipe 42 has a hollow structure, with radially extending air supply holes 421 on its sidewalls that communicate with the inner side. One end of each air supply pipe 42 extends out of the drying chamber 10 and connects to a hot air distribution pipe 34, while the other end extends out of the drying chamber 10 and connects to the drive module 41. During operation, hot air enters different air supply pipes 42 through multiple hot air distribution pipes 34. The drive module 41 drives several air supply pipes 42 to rotate synchronously, causing the air supply holes 421 to evenly and oscillate as they rotate, blowing hot air onto the medicinal materials on the support net 20. This effectively solves the problem of uneven hot air distribution and uneven drying quality in traditional drying chambers 10.

[0041] Specifically, the drive module 41 includes a drive motor 411, a drive wheel 412, and a transmission belt 413; one end of the air duct 42 away from the hot air supply mechanism 30 extends out of the drying chamber 10 and is connected to the transmission wheel 422; the drive wheel 412 is fixed to the output end of the drive motor 411, and the drive wheel 412 and the transmission wheel 422 are engaged with the inner side of the transmission belt 413. The drive motor 411 drives the drive wheel 412 to rotate, thereby causing the transmission belt 413 to roll, which in turn drives the transmission wheel 422 and the air duct 42 to rotate, thus realizing the rotation of the air duct 42. The drive motor 411 is fixed to the side of the drying chamber 10, and a dust cover 43 is fitted on the outer side of the drive module 41.

[0042] Specifically, both ends of the air supply duct 42 are fitted with rotating bearings 423, and the air supply duct 42 is rotatably connected to the drying chamber 10 through the rotating bearings 423, which ensure smooth rotation of the air supply duct 42. In particular, the air supply holes 421 are arranged at intervals along the axial direction of the air supply duct 42, and all air supply holes 421 are opened facing the same side of the air supply duct 42, forming a directional air supply area. This design, by limiting the distribution range of the air supply holes 421, ensures that hot air is concentratedly blown to a specific area of ​​the support net 20, and achieves a swing-type uniform air supply effect in conjunction with the rotational movement of the air supply duct 42.

[0043] The working principle of the circulating open drying box for Chinese medicine involved in this utility model is as follows: the heating module 32 generates heat, the blowing module 31 delivers air, the air absorbs heat when passing through the heating module 32 to form hot air, the hot air enters into different air delivery pipes 42 through different hot air distribution pipes 34, the driving module 41 drives multiple air delivery pipes 42 to swing synchronously, and during the rotation, the hot air is blown out through the air delivery hole 421, and the hot air is concentrated and blown onto the carrying net 20 to dry the medicinal materials.

[0044] Compared to existing technologies, the circulating open-type drying box for traditional Chinese medicine involved in this invention achieves uniform and efficient drying of medicinal materials through the optimized design of a synchronously rotating air supply pipe 42, combined with the hot air supply mechanism 30 and the support net 20. Multiple air supply pipes 42 rotate synchronously under the drive module 41, causing hot air to be blown in an oscillating manner through the radial air supply holes 421, effectively solving the problem of uneven hot air distribution in traditional drying boxes 10. The interconnected design of the heating module 32 and the blowing module 31 ensures the stability of the hot air supply, while the matching installation of the support net 20 and the slot 12 of the drying chamber 11 ensures the stability of the medicinal materials. This structure not only improves the quality and efficiency of medicinal material drying but also facilitates equipment cleaning and maintenance through the detachable support net 20 design and sealing ring 35, offering significant advantages such as simple structure, reliable operation, energy saving, and environmental protection.

[0045] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
