Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical manufacturing equipment technology, and in particular to a drum-type drying device for traditional Chinese medicine decoction pieces. Background Technology

[0002] Traditional Chinese medicine (TCM) decoction pieces are TCM raw materials that have been processed according to TCM theory and processing methods, and can be directly used in TCM clinical practice. This concept indicates that there is no absolute boundary between TCM raw materials and TCM decoction pieces. TCM decoction pieces include some TCM slices processed at the place of origin, raw medicinal materials decoction pieces, and decoction pieces that have been cut and processed. The first two categories should be regarded as TCM raw materials in management, but they are understood as decoction pieces in prescription and preparation according to TCM theory.

[0003] In the production process of Chinese herbal medicine slices, most slices require drying, which extends their storage time. However, existing Chinese herbal medicine drying equipment still faces the following technical problems in actual drying operations:

[0004] Existing traditional drying equipment commonly suffers from uneven temperature control during the drying process. This results in some areas of the medicinal herbs becoming excessively hot during drying, leading to a significant loss of active ingredients and severely impacting the quality and efficacy of the herbs. Furthermore, the processing techniques rely heavily on the individual experience of operators, lacking standardized procedures. From the initial processing of medicinal materials to key steps such as drying temperature, time, and frequency of turning, there are no unified standards. This leads to significant variations in results among different operators, making it difficult to guarantee consistent and stable product quality and hindering the large-scale and standardized development of the traditional Chinese medicine processing industry.

[0005] In response to this technical problem, this application proposes a drum-type drying device for traditional Chinese medicine decoction pieces. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as uneven drying leading to loss of effective components and the fact that processing techniques largely rely on operator experience and lack standardized procedures. This invention proposes a drum-type drying device for Chinese medicinal herbs. The device achieves different heating methods for materials by using different rotational speeds in the outer and inner drums, meeting the drying temperature and turning frequency requirements of different herbs and reducing the loss of effective components in heat-sensitive herbs. Furthermore, the pre-drying steam conditioning combined with a hot air blower achieves gradient heating, providing support for the standardization of processing techniques.

[0018] This invention achieves a difference in rotation speed between the outer and inner rotating drums, allowing materials to be heated in different areas in varying ways. This fully meets the diverse needs of herbs with different particle sizes or heat sensitivities for drying temperature and turning frequency. For example, for herbs with high heat sensitivity, the relatively gentle stirring and rotation speed of the inner drum allows them to be slowly dried at a suitable temperature, effectively reducing the loss of active ingredients due to unsuitable temperature and significantly improving the uniformity of drying quality.

[0019] This invention utilizes a steam-moistening treatment of medicinal herbs before drying, allowing them to absorb an appropriate amount of moisture and soften their internal structure. Simultaneously, a hot air blower at the rear blows hot air from back to front, creating a gradient heating environment—the temperature increases towards the back of the herb—effectively preventing damage to the active ingredients caused by sudden or sustained high temperatures, thus comprehensively ensuring the quality of the prepared Chinese medicine slices. This standardized drying process provides solid hardware support for the processing technology, greatly reducing reliance on manual experience and significantly improving drying efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figure 2 , Figure 4 and Figure 5This utility model provides an embodiment of a rotary drum drying device for traditional Chinese medicine decoction pieces, comprising a base 1; a feeding box 2 is installed on the top of the base 1; an arc-shaped groove 39 is opened on the top left side of the outer wall of the feeding box 2; an observation window 3 is rotatably connected to the top front side of the feeding box 2; a humidifying hopper 4 is rotatably connected to the inner wall of the feeding box 2; a partition 5 is fixedly connected to the middle of the inner wall of the humidifying hopper 4; a pouring plate 7 is fixedly connected to the left and right ends of the rear side of the outer wall of the humidifying hopper 4; a reserved opening 6 is opened on the left and right ends of the front side of the outer wall of the humidifying hopper 4; a feeding plate 8 is fixedly connected to the bottom end of the inner wall of the reserved opening 6; a sliding rod 9 is fixedly connected to the top left side of the outer wall of the humidifying hopper 4; the sliding rod 9 is slidably connected inside the arc-shaped groove 39; a positioning block 10 is installed on the left side of the outer side of the sliding rod 9; the positioning block 10 is connected to a fixed seat 12 through a movable component 11; the fixed seat 12 is fixedly connected to the left side of the outer wall of the feeding box 2; a steam injection component 13 is fixedly connected to the top side of the inner wall of the feeding box 2; and the rear side of the base 1... The base 16 is fixedly connected to the bottom. Support rods 17 are fixedly connected to the front ends of both the left and right sides of the base 16. A support sleeve 18 is fixedly connected to the top of each support rod 17. A feed inlet 19 is provided on the front side of the support sleeve 18. A through plate 20 is fixedly connected to the bottom end of the inner wall of the feed inlet 19. An outer rotating cylinder 22 is connected to the base 16 via a rotating assembly 21. A transmission assembly 27 is installed on the front end of the inner wall of the outer rotating cylinder 22. The outer rotating cylinder 22 is connected to an inner rotating cylinder 22 via the transmission assembly 27. 8. A fixing sleeve 32 is installed at the rear end of the outer wall of the inner rotating cylinder 28. A discharge port 38 is opened on the bottom side of the inner wall of the fixing sleeve 32. The fixing sleeve 32 is connected to the support sleeve 24 through the fixing rod 31. A support base 25 is fixedly connected to the rear end of the bottom side of the outer wall of the support sleeve 24. A discharge port 26 is opened at both the front and rear ends of the bottom side of the inner wall of the support sleeve 24. A vent pipe 34 is fixedly connected to the rear side of the outer wall of the support sleeve 24. A hot air blower 35 is installed on the rear side of the vent pipe 34.

[0029] Specifically, the main function of the positioning block 10 is to firmly lock and fix the slide rod 9 at the top position during normal operation. At this time, the steaming hopper 4 remains in a stable and upright state, which facilitates the steam steaming of Chinese herbal medicine slices inside and prevents the steaming hopper 4 from accidentally shaking or tipping over, thus affecting the steaming effect. When it is necessary to pour out the steamed Chinese herbal medicine slices, the operator can operate the positioning block 10 to make it work in conjunction with the movable component 11 to slide and release the fixation on the slide rod 9. In this way, the slide rod 9 can slide smoothly in the arc groove 39, thereby driving the steaming hopper 4 to rotate and realize the pouring action. The operation is convenient, precise and controllable. The sliding groove 1102 in the movable component 11 is located on the rear side of the fixed base 12 and is slidably connected to the positioning block 10. The limiting groove 1103 is located on the left side of the outer wall of the fixed base 12. The limiting block 1101 is installed on the inner wall of the limiting groove 1103 and is fixedly connected to the front side of the positioning block 10. This structure allows the moistening hopper 4 to slide in the arc groove 39 via the sliding rod 9, enabling flexible rotation and facilitating material pouring. The positioning block 10, in cooperation with the movable component 11, can accurately position the moistening hopper 4, ensuring operational accuracy. The steam jet component 13, fixedly connected to the top side of the inner wall of the feeding box 2, is connected to the steam generator 15 via the pipe 14. The steam generator 15 is installed at the top right end of the base 1 and can generate steam to moisten the Chinese herbal medicine slices in the moistening hopper 4. Steam moistening allows the medicinal materials to absorb an appropriate amount of moisture, softening their internal structure and creating favorable conditions for subsequent drying, thus improving drying efficiency and quality.

[0030] The outer rotating drum 22 primarily accommodates and initially turns the material. Multiple lifting plates 33 fixed to its rear inner wall lift and scatter the medicinal herbs during rotation, allowing for large-area contact between the material and hot air, achieving initial drying and position adjustment. Meanwhile, the stirring plates 29 fixed to the front outer wall of the inner rotating drum 28 initially stir and disperse the material inside the outer drum 22 during its operation. This action separates any clustered or adhered medicinal herbs, evenly dispersing the material and greatly improving its spatial uniformity. As a result, all parts of the material can equally contact the hot air during subsequent drying, preventing localized overheating or under-drying, ensuring each medicinal herb fully absorbs heat, accelerating moisture evaporation, and working in conjunction with the outer rotating drum 22 to significantly improve the uniformity, efficiency, and consistency of drying quality, comprehensively optimizing the drying process for medicinal herbs. Meanwhile, the inner rotating drum 28 rotates at a faster speed than the outer rotating drum 22. Therefore, medicinal materials with low heat sensitivity can be placed in the inner rotating drum 28 for simultaneous drying, preventing the loss of effective components due to overheating. This meets the personalized drying needs of various medicinal materials, improving production flexibility and work efficiency.

[0031] Reference Figure 1 , Figure 3 and Figure 5The top of the steam jet 13 penetrates the top of the feed box 2 and is fixedly connected to a pipe 14. A steam generator 15 is installed at the right end of the pipe 14. The steam generator 15 is installed at the top right end of the base 1. The movable component 11 includes a slide groove 1102 and a limiting groove 1103. The slide groove 1102 is opened on the rear side of the fixed base 12 and is slidably connected to the positioning block 10. The limiting groove 1103 is opened on the left side of the outer wall of the fixed base 12. A limiting block 1101 is installed on the inner wall of the limiting groove 1103. The limiting block 1101 is fixed. A thrust wheel 23 is fixedly connected to the front side of the positioning block 10. Thrust wheels 23 are installed at both the front and rear ends of the top of the machine base 16. The top side of the thrust wheel 23 is in contact with the outer wall of the outer rotating cylinder 22. The rotating assembly 21 includes a motor 2101 and a gear 2103. The motor 2101 is fixedly connected to the middle of the top of the machine base 16. A gear 2102 is fixedly connected to the drive end of the motor 2101. The gear 2103 is fixedly connected to the middle of the outer wall of the outer rotating cylinder 22, and the gear 2103 meshes with the gear 2102. The rear end of the inner wall of the outer rotating cylinder 22 is fixedly connected to... There are multiple lifting plates 33. A stirring plate 29 is fixedly connected to the front end of the outer wall of the inner rotating cylinder 28. A vent hole 30 is opened in the middle of the outer wall of the inner rotating cylinder 28. The front end of the outer wall of the outer rotating cylinder 22 is rotatably connected to the inner wall of the first support sleeve 18. The rear end of the outer wall of the outer rotating cylinder 22 is rotatably connected to the inner wall of the second support sleeve 24. The rear end of the outer wall of the inner rotating cylinder 28 is rotatably connected to the inner wall of the fixed sleeve 32. The fixed rod 31 is fixedly connected to the outer wall of the fixed sleeve 32. The top end of the fixed rod 31 is fixedly connected to the inner wall of the second support sleeve 24. The transmission assembly 27 includes a second tooth 27. 01 and tooth 2701 are fixedly connected to the front end of the inner wall of the outer rotating cylinder 22, and tooth 2703 is fixedly connected to the front end of the outer wall of the inner rotating cylinder 28. Tooth 2701 is connected to tooth 2703 through gear 2702. Tooth 2703 is rotatably connected to the top end of the front side of the inner wall of the support sleeve 18. The right end of the front side of the outer wall of the support sleeve 18 is equipped with an exhaust pipe 37. The rear end of the exhaust pipe 37 passes through the front side of the support sleeve 18. A ventilation hole 36 is opened on the rear side of the outer wall of the fixed sleeve 32.

[0032] Specifically, when the motor 2101 is working, it drives the gear 2102 to rotate, thereby causing the outer rotating cylinder 22 to rotate around the axis. The top side of the thrust wheel 23 installed at the front and rear ends of the top of the base 16 is in contact with the outer wall of the outer rotating cylinder 22, which can help support the outer rotating cylinder 22, reduce the friction during rotation, and improve the rotational stability. The outer rotating drum 22 is connected to the inner rotating drum 28 via a transmission assembly 27. Gear 2701 in the transmission assembly 27 is fixed to the front end of the inner wall of the outer rotating drum 22, and gear 2703 is fixed to the front end of the outer wall of the inner rotating drum 28. Gear 2701 is connected to gear 2702 via gear 2702. Gear 2703 is rotatably connected to the top front side of the inner wall of the support sleeve 18. When the outer rotating drum 22 rotates, it drives gear 2701 and gear 2702 to drive gear 2703, which in turn drives the inner rotating drum 28 to rotate. Since the two rotating drums rotate at different speeds, they can tumble and stir the medicinal herbs to varying degrees, improving the uniformity of drying. Multiple lifting plates 33 fixedly connected to the rear end of the inner wall of the outer rotating drum 22 can lift and drop the medicinal herbs during rotation, increasing the contact area between the material and hot air. Stirring plates 29 fixedly connected to the front end of the outer wall of the inner rotating drum 28 stir the material inside, further promoting uniform heating.

[0033] The ventilation hole 30 at the middle of the outer wall of the inner rotating cylinder 28 facilitates the circulation of hot air between the cylinders, enhancing the drying effect. The front end of the outer wall of the outer rotating cylinder 22 is rotatably connected to the inner wall of the first support sleeve 18, and the rear end is rotatably connected to the inner wall of the second support sleeve 24. The rear end of the outer wall of the inner rotating cylinder 28 is rotatably connected to the inner wall of the fixed sleeve 32. The fixed sleeve 32 is connected to the second support sleeve 24 via a fixed rod 31. This connection method ensures the stability and coordination of the rotation of each component. The support seat 25 fixedly connected to the rear end of the bottom side of the outer wall of the second support sleeve 24 provides additional support. The discharge port 26 at the front and rear ends of the bottom side of the inner wall of the second support sleeve 24 and the discharge port 38 at the bottom side of the inner wall of the fixed sleeve 32 facilitate the discharge of the dried Chinese herbal medicine pieces. A vent pipe 34, fixedly connected to the rear side of the outer wall of support sleeve 24, is connected to a hot air blower 35. Hot air generated by the hot air blower 35 enters support sleeve 24 through vent pipe 34, and then enters the outer rotating drum 22 and the inner rotating drum 28 to provide heat for drying. An exhaust pipe 37 installed at the right end of the front side of the outer wall of support sleeve 18 can promptly discharge exhaust gas generated during the drying process, maintaining a good drying environment. Ventilation holes 36 on the rear side of the outer wall of fixed sleeve 32 facilitate air circulation, further optimizing the drying effect.

[0034] Working principle: During operation, steam generator 15 generates steam, which is sent through pipe 14 and steam injection component 13 into the steam-soaking hopper 4 in the feed box 2 to steam-soak the Chinese herbal medicine slices. During this process, positioning block 10 fixes slide rod 9 to keep steam-soaking hopper 4 upright. After steaming, the positioning block 10 cooperates with movable component 11 to make slide rod 9 slide in arc groove 39, driving steam-soaking hopper 4 to pour out the material. The material enters outer rotating drum 22 and inner rotating drum 28 through feed port 19 and through plate 20. Motor 2101 on machine base 16 drives gear 1 2102 to rotate, driving outer rotating drum 22 to rotate around the axis. Thrust wheel 23 provides auxiliary support to reduce friction. 2. The inner rotating drum 28 is driven to rotate at different speeds by the transmission component 27. The lifting plate 33 on the inner wall of the outer rotating drum 22 lifts up and sprinkles the Chinese herbal medicine pieces. The stirring plate 29 on the outer wall of the inner rotating drum 28 stirs and disperses the materials. At the same time, the hot air generated by the hot air blower 35 enters the second support sleeve 24 through the air pipe 34 and then enters the outer rotating drum 22 and the inner rotating drum 28 to provide heat for drying. The hot air between the rotating drums circulates through the air hole 30 on the outer wall of the inner rotating drum 28 to improve the drying effect. The waste gas generated during the drying process is discharged through the waste gas discharge pipe 37. Finally, the dried Chinese herbal medicine pieces are discharged through the discharge port 26 on the inner wall of the second support sleeve 24 and the discharge port 38 on the inner wall of the fixed sleeve 32.
