Description

Technical Field

[0001] This application relates to the technical field of traditional Chinese medicine processing, and in particular to a multi-stage heat transfer drying device for traditional Chinese medicine. Background Technology

[0002] Traditional Chinese medicine (TCM) herbs must have their internal moisture removed during storage to maintain their medicinal efficacy and prevent spoilage. The traditional method involves a drying device containing a heater upon which a multi-tiered rack for the herbs is placed. This rack consists of multiple horizontal plates supported by vertical connecting columns. The herbs are laid flat on these plates to receive heat for drying. The heat generated by the heater acts directly on the bottom plate and is then transferred upwards through the connecting columns, evaporating the moisture from the herbs.

[0003] However, this design of the herbal medicine rack has significant flaws. The bottom shelf is in close contact with the heater, causing the herbs in this layer to heat up rapidly and evaporate moisture quickly. However, the heat from the second shelf can only be conducted from the first shelf through the connecting columns, resulting in low heat transfer efficiency. Similarly, the heat from the third and higher shelves is indirectly transferred from the lower layers through the connecting columns, leading to insufficient heating of the upper layers. This uneven heat distribution causes the herbs in the first layer to dry too quickly, while the drying speed decreases as you move upwards. This results in a longer processing time and lower work efficiency. Utility Model Content

[0004] To address the problem of uneven heat distribution in traditional Chinese medicine drying devices, which results in faster drying at the bottom and slower drying at the top, this application provides a layered heat transfer type Chinese medicine drying device.

[0005] The hierarchical heat transfer type traditional Chinese medicine drying device provided in this application adopts the following technical solution: A multi-stage heat transfer type traditional Chinese medicine drying device includes a heater and a traditional Chinese medicine carrying assembly. The heater has a heating block, and the traditional Chinese medicine carrying assembly is mounted on the heating block. A serpentine heating tube is installed inside the heating block. The traditional Chinese medicine carrying assembly includes a first support box, a second support box, and a top cover. The first support box is mounted on the heating block, the second support box is mounted on the first support box, and the top cover is mounted on the second support box. The first support box contains multiple partition blocks. The second support box also contains multiple partition blocks. Each partition block has a heat transfer groove. Multiple heat transfer blocks are installed at the lower end of the second support box, and these heat transfer blocks are inserted into the heat transfer grooves on the first support box. The first support box has a first vent, and the second support box has a second vent.

[0006] By adopting the above technical solution, this solution divides the internal space into multiple small compartments by setting up a first support box and a second support box, and incorporating partition blocks within the boxes. This increases the heating area, allowing the Chinese medicine to be heated from multiple directions—the bottom, side walls, and the side walls of the partition blocks—improving heat conduction efficiency and ensuring uniform heating of the Chinese medicine. The interlocking connection between the heat transfer block and the heat transfer groove provides the main path for heat transfer from the first support box to the second support box, promoting heat conduction between layers. The placement of the first and second vents optimizes the ventilation environment inside the device, facilitating the removal of moisture and heat.

[0007] Preferably, the heating block has a heating groove, and the serpentine heating tube is divided into a horizontal section and a vertical section. The horizontal section is used to heat the bottom of the first support box, and the vertical section is used to heat the side wall of the first support box.

[0008] By adopting the above technical solution, this solution divides the serpentine heating tube into horizontal and vertical sections to heat the bottom and side walls of the first support box respectively, thereby achieving multi-directional heating of the first support box, further improving heat conduction efficiency, and ensuring that the Chinese medicine in the first support box is heated more evenly.

[0009] Preferably, the inner wall of the heating groove is provided with a first transition fillet, and the outer wall of the first support box is provided with a second transition fillet.

[0010] By adopting the above technical solution, this solution increases the heat transfer contact area between the heating tank and the first support box by setting the first transition fillet and the second transition fillet, thereby improving the heat conduction efficiency.

[0011] Preferably, the inner wall of the first support box is provided with a third transition rounded corner.

[0012] By adopting the above technical solution, this solution eliminates the thermal stress concentration at the corner of the inner wall of the first support box by setting a third transition fillet, preventing structural damage caused by repeated hot and cold cycles and extending the service life of the device.

[0013] Preferably, the inner wall of the second support box is provided with a fourth transition rounded corner.

[0014] By adopting the above technical solution, this solution eliminates the thermal stress concentration at the corner of the inner wall of the second support box by setting a fourth transition fillet, preventing structural damage caused by repeated hot and cold cycles and extending the service life of the device.

[0015] Preferably, the first support box is further provided with a connecting groove, and the second support box is further provided with a connecting post, the connecting post being inserted into the connecting groove; the second support box is also provided with a connecting groove.

[0016] By adopting the above technical solution, this solution achieves accurate positioning and reliable connection between the first support box and the second support box through the plug-in cooperation of the connecting column and the connecting groove, which increases the contact area, enhances the heat conduction between layers, and improves the stability of the overall structure.

[0017] Preferably, the top cover is provided with a lifting head.

[0018] By adopting the above technical solution, this solution facilitates the removal and placement of the top cover by setting up a lifting head.

[0019] Preferably, the top cover is also provided with a plug-in post.

[0020] By adopting the above technical solution, this solution achieves accurate positioning and connection between the top cover and the second support box through the setting of plug-in posts, ensuring the sealing and stability of the overall structure.

[0021] In summary, this application includes the following beneficial technical effects: The serpentine heating tubes within the heating block are divided into horizontal and vertical sections, heating the bottom and side walls of the first support box respectively, achieving multi-directional heating. Dividing blocks within the first and second support boxes divide the internal space into multiple small compartments, increasing the heating area and allowing the Chinese medicine to be heated simultaneously from the bottom, side walls, and the side walls of the dividing blocks. The interlocking connection between the heat transfer block and the heat transfer groove forms the main path for heat transfer from the first to the second support box, ensuring efficient heat conduction between layers. The first and second vents optimize the ventilation environment, promoting the removal of moisture and heat. The interlocking connection between the connecting column and the connecting groove enhances heat conduction between layers and structural stability. The rounded transition corners reduce thermal stress concentration and prevent structural cracks. These design features work together to achieve uniform heating and efficient drying of the Chinese medicine, improving work efficiency. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0030] This application discloses a hierarchical heat transfer type traditional Chinese medicine drying device, referring to... Figure 1 The device includes a heater 1 and a traditional Chinese medicine carrier component 2. In this embodiment, the heater 1 is vertically arranged, and the traditional Chinese medicine carrier component 2 is vertically arranged on the heater 1. The traditional Chinese medicine carrier component 2 is used to carry traditional Chinese medicine, and the heater 1 is used to heat the traditional Chinese medicine carrier component 2.

[0031] Reference Figures 1-2 A heating block 11 is fixedly connected to the upper end of the heater 1, and a heating groove 111 is formed on the upper end of the heating block 11. The Chinese medicine carrying component 2 includes a first support box 21, a second support box 22, and a top cover 23. The first support box 21 is vertically arranged in the heating groove 111, and the second support box 22 is vertically arranged on the upper end of the first support box 21. In this embodiment, the second support box 22 is provided in two layers, and the top cover 23 is arranged on the upper end of the highest layer of the second support box 22. A lifting head 232 is fixedly connected to the upper end of the top cover 23.

[0032] Reference Figures 2-4 A serpentine heating tube 112 is fixedly connected inside the heating block 11. In this embodiment, the serpentine heating tube 112 is divided into a vertical section and a horizontal section. The horizontal section is laid horizontally inside the heating block 11, and the vertical section is set vertically inside the heating block 11. The first support box 21 is located inside the heating groove 111. The horizontal section of the serpentine heating tube 112 is used to heat the bottom of the first support box 21, and the vertical section of the serpentine heating tube 112 is used to heat the side walls of the first support box 21.

[0033] Reference Figure 2 , Figure 5 and Figure 6The first support box 21 has a first vent hole 212 on its side wall. A vertically extending connecting groove 113 is arranged around the edge of the opening at the upper end of the first support box 21. Correspondingly, a connecting post 224, matching the shape and size of the connecting groove 113, is provided around the bottom outer periphery of the second support box 22. The connecting post 224 is inserted into the connecting groove 113. The first support box 21 has multiple vertically arranged partition blocks 211, each with a vertically formed heat transfer groove 2111. The partition blocks 211 divide the internal space of the first support box 21 into multiple small compartments. Multiple heat transfer blocks 221 are vertically fixedly connected to the lower end of the second support box 22, and these heat transfer blocks 221 are inserted into the heat transfer grooves 2111. In this embodiment, each heat transfer block 221 has a row of third vent holes 2211 along the short axis of the first support box 21, and the axis of the third vent holes 2211 is parallel to the long axis of the first support box 21. Each partition block 211 has a row of fourth vent holes 2112, and each fourth vent hole 2112 is aligned with a corresponding third vent hole 2211. The second support box 22 also has partition blocks 211 with the same structure as the first support box 21. At the edge of the upper opening of the second support box 22, a vertically extending connecting groove 113 is also arranged around it. The side wall of the second support box 22 has a second vent hole 222.

[0034] Reference Figure 2 , Figure 5 and Figure 6 Through the design of the aforementioned partition block 211, the internal space of the first support box 21 and the second support box 22 is divided into multiple independent small compartments. This allows the Chinese medicine to be distributed in various small compartments instead of simply being laid flat on a large plate. The advantage of this layout is a significant increase in heating area: in traditional plate structures, the Chinese medicine is heated only by the bottom of the plate; however, in this embodiment, the Chinese medicine is heated not only by the bottom of the support box but also by the side walls of the support box and the side walls of the partition block 211. This multi-directional heating method effectively improves heat conduction efficiency, ensuring more uniform heating of the Chinese medicine and thus improving the drying effect.

[0035] Reference Figure 2 , Figure 5 and Figure 6 A ring of insertion posts 231, which are in shape and size matching the connecting groove 113, is provided on the lower outer periphery of the top cover 23. The insertion posts 231 are inserted into the connecting groove 113 of the second support box 22 on the highest layer.

[0036] Reference Figure 2 , Figure 5 and Figure 6To achieve better heat transfer, this embodiment enhances the heat conduction efficiency between the first support box 21 and the second support box 22 by interlocking the connecting post 224 with the connecting groove 113. The interlocking of the connecting post 224 and the connecting groove 113 not only serves for positioning and connection but also increases the contact area between them, allowing heat to be transferred more quickly from the first support box 21 to the second support box 22, thereby improving the drying effect on the traditional Chinese medicine. The interlocking post 231 on the top cover 23 interlocks with the connecting groove 113 located at the uppermost end of the second support box 22. Through the interlocking of the interlocking post 231 and the connecting groove 113, accurate positioning and reliable connection between the top cover 23 and the second support box 22 can be achieved, ensuring the stability of the overall structure.

[0037] Reference Figures 4-6 The inner wall of the heating tank 111 is provided with a first transition fillet 1111, and the outer wall of the first support box 21 is provided with a corresponding second transition fillet 213. This fillet design effectively increases the heat transfer contact area between the heating tank 111 and the first support box 21, thereby improving heat conduction efficiency. Furthermore, the inner walls of the first support box 21 and the second support box 22 are respectively provided with a third transition fillet 214 and a fourth transition fillet 223. This design aims to eliminate thermal stress concentration at corners during repeated heating and cooling cycles, thereby preventing structural cracks caused by stress concentration and ensuring the structural safety and service life of the device during long-term use.

[0038] The implementation principle of the hierarchical heat transfer type traditional Chinese medicine drying device in this application embodiment is as follows: Heater 1 is activated, and the serpentine heating tube 112 heats the heating block 11. Heat is transferred through the heating block 11 to the bottom and side walls of the first support box 21. The interior of the first support box 21 is divided into multiple independent small compartments by partition blocks 211. Heat is simultaneously applied from the bottom and side walls of the first support box 21 and the side walls of the partition blocks 211 to heat the traditional Chinese medicine placed in the small compartments in multiple directions, increasing the heating area. The heat transfer groove 2111 on the partition block 211 is inserted and engaged with the heat transfer block 221 fixed to the bottom of the second support box 22, forming the main path for heat transfer from the first support box 21 to the second support box 22. The third vent 2211 on the heat transfer block 221 is aligned with the fourth vent 2112 on the partition block 211, facilitating the circulation of hot air within a small area.

[0039] The first vent 212 on the side wall of the first support box 21 facilitates the discharge of hot and humid air from inside the first support box 21. The second vent 222 on the side wall of the second support box 22 facilitates the discharge of hot and humid air from inside the second support box 22. The arrangement of these vents together optimizes the overall ventilation environment inside the device.

[0040] The insertion and engagement of the upper connecting groove 113 of the first support box 21 and the bottom connecting post 224 of the second support box 22 increases the contact area between the two and forms an auxiliary heat conduction path between the layers.

[0041] This application achieves efficient core heat transfer between layers through the main heating path formed by the heat transfer block 221 and the heat transfer groove 2111, making the drying speed of Chinese medicine in each layer more consistent, thereby improving the overall drying efficiency.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
