Description

Technical Field

[0001] This application relates to the technical field of equipment for processing traditional Chinese medicine, and in particular to a constant temperature air drying device for processing traditional Chinese medicine. Background Technology

[0002] Air drying of medicinal herbs is a common processing method in the processing of traditional Chinese medicine. Its function is to evaporate the moisture in some raw materials, thereby concentrating the medicinal effects and extending their shelf life. Existing air drying equipment often uses indoor shelves for stacking and circulates hot air inside to remove moisture. However, this drying environment requires a large volume of raw materials. For drying smaller materials, there is a lack of suitable drying equipment. The current solution is to use sheet metal boxes for storage and circulate hot air at the bottom to achieve the drying process. However, during the air drying process, the raw materials are often piled up thickly, which leads to uneven drying and affects the quality of the finished product. To solve the problem of uneven drying, it is often necessary to extend the drying time or stir the materials midway, which reduces drying efficiency and increases labor intensity. Therefore, it is necessary to improve the existing methods to solve these problems. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the purpose of this application is to provide a constant temperature air drying device for traditional Chinese medicine processing that combines multi-position air supply and uniform material rotation, achieving high air drying uniformity, shortening drying efficiency, and reducing labor intensity.

[0004] The above-mentioned objective of this application is achieved through the following technical solution: A constant-temperature air-drying device for processing traditional Chinese medicine includes: a carrying cylinder, a partition, a turntable, toothed grooves, a drive motor, a drive gear, a support frame, a placement net, a hot air blower body, an air inlet pipe, an air guide pipe, a branch air pipe, an exhaust vent, a door panel, and a conical cover. The carrying cylinder has open ends and a notch on one side. The partition is fixedly connected to the inner wall of the carrying cylinder near its lower end. The turntable is rotatably connected to the middle of the partition. The toothed grooves are arranged in a ring array at the lower edge of the turntable. The drive motor is located below the partition, and the drive gear is fixedly connected to the end of the drive motor's output shaft. The support frame is fixedly connected to the upper end of the turntable and has several layers of support surfaces. The placement nets are respectively connected to each layer of the support frame. The hot air blower body is located below the partition. One end of the air inlet pipe is connected to one side of the bottom of the bearing cylinder, and the other end of the air inlet pipe is connected to the air inlet of the hot air blower body. Two air guide pipes are connected to both sides of the hot air blower body, and the two air guide pipes extend symmetrically into the inner wall of the upper end of the bearing cylinder. The air distribution branch pipes are respectively connected to the air guide pipes at corresponding horizontal positions below each layer of the support frame. The exhaust holes are equidistantly opened on the upper surface of the air distribution branch pipes. The door panel is movably connected to the edge of the notch opened on one side of the bearing cylinder. The conical cover is connected to the upper end of the bearing cylinder, and a through hole is provided in the middle of the conical cover.

[0005] Optionally, it also includes an exhaust pipe, which is fixedly connected to the upper end of the through hole in the middle of the conical cover.

[0006] Optionally, it also includes an observation window, which is located in the middle of the door panel and is fitted with a high-temperature resistant glass plate.

[0007] Optionally, a connecting flange is also included, which is fixedly connected to the upper end of the exhaust pipe.

[0009] Optionally, it also includes ventilation grooves, which are arranged in a circular array and pass through the bottom of the support cylinder.

[0010] This constant temperature air drying device for processing traditional Chinese medicine adopts a modular structure, which can realize the layered placement of materials, reduce the stacking thickness of each layer, and allow each layer to be supplied with air separately. Combined with the rotating placement structure, it achieves a high degree of temperature uniformity and better drying quality. This constant temperature air drying device for Chinese medicine processing can meet the air drying needs of some small-volume materials. It does not require manual turning during operation and has a faster drying speed compared with existing drying equipment. It solves the actual needs of the factory and has good application prospects. This constant temperature air drying device for processing traditional Chinese medicine can disperse the generated drying air through the set air pipes and air distribution branches, so that different temperatures can reach different positions inside the bearing cylinder evenly. Then, with the cooperation of the rotating support frame, it can achieve uniform coverage of each layer, resulting in a more stable air drying effect and good practicality.

[0013] The present application will be further described in detail below with reference to the accompanying drawings.

[0014] To better understand the technical solutions presented in the embodiments of this application, the working principle of existing constant temperature air drying devices for processing traditional Chinese medicine will first be introduced.

[0015] In existing important processing air-drying equipment, the temperature of the hot air generated by the air-drying equipment can be kept constant to ensure basic stability. However, after the hot air with constant temperature enters the drying equipment, due to the different thickness of the Chinese medicinal materials and the fixed position of the air inlet, the material temperature near the bottom inlet is higher, while the material temperature in the thicker areas is lower. The drying speed is not uniform, and after a certain period of time, the internal materials are not dry to the same degree, so manual turning is required. Therefore, it is necessary to improve the structure of the existing air-drying equipment to solve these problems.

[0016] Please see Figures 1 to 4This application discloses a constant temperature air-drying device for processing traditional Chinese medicine, comprising: a carrying cylinder 1, a partition 2, a turntable 3, a toothed groove 4, a drive motor 5, a drive gear 6, a support frame 7, a placement net 8, a hot air blower body 9, an air inlet pipe 10, an air guide pipe 11, a branch air pipe 12, an exhaust vent 13, a door panel 14, and a conical cover 15. The upper and lower ends of the carrying cylinder 1 are open, and a notch is opened on one side of the carrying cylinder 1. The partition 2 is fixedly connected to the inner wall of the carrying cylinder 1 near the lower end. The turntable 3 is rotatably connected to the middle of the partition 2. The toothed groove 4 is arranged in a ring array at the lower edge of the turntable 3. The drive motor 5 is located below the partition 2. The drive gear 6 is fixedly connected to the end of the output shaft of the drive motor 5. The support frame 7 is fixedly connected to the upper end of the turntable 3. The support frame 7 has several layers of support surfaces. The net 8 is connected to each layer of support surface of the support frame 7. The hot air blower body 9 is located below the partition plate 2. One end of the air inlet pipe 10 is connected to one side of the bottom of the bearing cylinder 1, and the other end of the air inlet pipe 10 is connected to the air inlet of the hot air blower body 9. Two air guide pipes 11 are connected to both sides of the hot air blower body 9, and the two air guide pipes 11 extend symmetrically into the inner wall of the upper end of the bearing cylinder 1. The air distribution branch pipes 12 are connected to the air guide pipes 11 at the corresponding horizontal positions below each layer of support surface of the support frame 7. The exhaust holes 13 are equidistantly opened on the upper surface of the air distribution branch pipes 12. The door panel 14 is movably connected to the edge of the notch opened on one side of the bearing cylinder 1. The conical cover 15 is connected to the upper end of the bearing cylinder 1, and a through hole is provided in the middle of the conical cover 15.

[0017] Specifically, during use, the placement nets 8 are placed on each layer of the support frame 7, thus dispersing the medicinal materials on different layers. After the door panel 14 is closed, the hot air blower body 9 at the bottom can draw in air through the air inlet pipe 10 and heat it. The heated air enters two air guide pipes 11 through two outlets, and then disperses to different heights through each air branch pipe 12. It is then discharged to the bottom of each layer of placement nets 8 through the exhaust vent 13, achieving basic complete coverage of both sides. The drive motor 5 drives the drive gear 6 to rotate, which in turn drives the turntable 3 to rotate through the tooth groove 4. When the turntable 3 rotates, it drives the support frame 7 to rotate as well, thus realizing the rotation of the placement nets 8 during the drying process, forming a drying and rotating effect simultaneously. The separate air supply for each layer ensures that the humidity of each layer can be fully removed, the drying speed is the same from top to bottom, the temperature coverage is more uniform, and there is no need for manual turning or extending the drying time in the middle, which greatly improves production efficiency. Compared with existing drying equipment, it is more flexible, has better application prospects, and is more easily accepted by people.

[0020] Please see Figure 1 As another specific embodiment provided in the application, it also includes an observation window 17, which is opened in the middle of the door panel 14, and a high-temperature resistant glass plate is installed at the observation window 17.

[0021] Specifically, the observation window 17 allows for easy and intuitive observation of the internal drying process, offering good flexibility and meeting the needs of real-world scenarios.

[0022] Please see Figure 3 As another specific embodiment provided in the application, it also includes a connecting flange 18, which is fixedly connected to the upper end of the exhaust pipe 16.

The input end of the control switch group 19 is electrically connected to the output end of the external power supply, and the output end of the control switch group 19 is electrically connected to the input ends of the drive motor 5 and the hot air blower body 9, respectively.

[0025] Specifically, the control switch group 19 can control the power of the drive motor 5 and the hot air blower body 9 separately to achieve automatic drying effect and meet the needs of different materials.

[0026] Please see Figure 2 As another specific embodiment provided in the application, it also includes ventilation grooves 20, which are arranged in a ring array and pass through the bottom of the support cylinder 1.

[0027] Specifically, the ventilation slots 20 prevent heat buildup at the bottom, keeping the bottom temperature within a certain range and improving safety.
