Description

Technical Field

[0001] This utility model relates to the field of Dendrobium officinale processing technology, and in particular to a drum-type drying device for processing Dendrobium officinale. Background Technology

[0002] Dendrobium officinale is a perennial epiphytic herb of the Orchidaceae family. It grows on semi-shaded and damp rocks in mountainous areas at an altitude of up to 1600 meters. It prefers a warm and humid climate and a semi-shaded environment. It is not cold-resistant, but can generally withstand a low temperature of -5℃. Dendrobium can be divided into dozens of varieties such as Huangcao, Jinchai, and Mabian. Dendrobium officinale is the best of the Dendrobium varieties. It is named for its iron-green epidermis.

[0003] However, when existing drying equipment processes Dendrobium officinale, the material tends to accumulate into clumps inside the drum. Especially in the initial processing stage when the Dendrobium officinale has a high moisture content, heat cannot penetrate the clumps, requiring the drying time to be extended to twice the traditional drying cycle. This not only increases energy consumption but also reduces the content of Dendrobium officinale polysaccharides due to prolonged heating, thus reducing the efficacy of Dendrobium officinale. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a drum-type drying device for processing Dendrobium officinale, which solves the technical problems of existing drying devices causing material to clump together when processing Dendrobium officinale with high moisture content, making it difficult for heat to penetrate, thus doubling the drying time, increasing energy consumption, and reducing polysaccharide content, thereby reducing its efficacy.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A drum-type drying device for processing Dendrobium officinale includes a heating cylinder. Supports are symmetrically fixedly installed at the lower end of the heating cylinder. A feeding plate is hinged to the side wall of the heating cylinder. A drive motor is fixedly installed on the side wall of the heating cylinder away from the feeding plate. A rotating shaft is fixedly installed at the output end of the drive motor. The rotating shaft is rotatably installed inside the heating cylinder. A side rod is fixedly installed on the side wall of the rotating shaft. A side strip is fixedly installed on the side wall of the side rod. A tamping strip is fixedly installed on the side wall of the side strip. This device enables the orderly feeding and driving stirring of Dendrobium officinale, increases the heating area for drying Dendrobium officinale, and enhances the drying effect.

[0007] Preferably, the side wall of the side rod is provided with a first inner groove and a discharge port. The discharge port is located below the first inner groove, providing a flow channel for materials so that the materials in the first inner groove can be discharged in an orderly manner through the discharge port.

[0008] Preferably, the discharge port is equipped with a dispersion tooth fixedly installed inside. The dispersion tooth is evenly distributed along the length of the discharge port, which can disperse the material discharged through the discharge port and prevent Dendrobium officinale from accumulating and clumping.

[0009] Preferably, the side strip has a second inner groove inside, and the lower end of the side strip has a discharge port, which is connected to the second inner groove, so that a material storage and discharge path is formed inside the side strip, ensuring the orderly flow of materials.

[0010] Preferably, a first guide strip is fixedly installed inside the second inner tank, which can guide the Dendrobium officinale in the second inner tank and provide directional guidance for the flow of materials.

[0011] Preferably, the first guide bar is provided with a guide groove, which is symmetrically distributed along the length of the first guide bar. The material is diverted by the symmetrically distributed grooves, so that the Dendrobium officinale flows more evenly.

[0012] Preferably, a second guide bar is fixedly installed inside the second inner tank. The second guide bar is located below the first guide bar, receiving the material above and guiding it a second time, thus extending the flow path of the material in the heating cylinder.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This equipment, through the synergistic action of the tamping strips, the first guide strip, the second guide strip, and the dispersing teeth, enables Dendrobium officinale to form an orderly flow, dispersion, and circulation within the heating cylinder. This significantly increases the contact area between Dendrobium officinale and the thermal environment inside the heating cylinder, effectively avoiding uneven drying in certain areas and significantly improving the drying efficiency and quality of Dendrobium officinale.

[0021] This application provides a drum-type drying device for processing Dendrobium officinale, which effectively solves the problems of existing drying devices that easily accumulate and clump together when processing Dendrobium officinale with high moisture content, making it difficult for heat to penetrate and doubling the drying time, increasing energy consumption, and reducing polysaccharide content, thus reducing its efficacy. This device, through the synergistic action of the tamping strip, the first guide strip, the second guide strip, and the dispersing teeth, enables Dendrobium officinale to form an orderly flow, dispersion, and circulation within the heating drum, greatly increasing the contact area between Dendrobium officinale and the thermal environment inside the heating drum, effectively avoiding uneven drying in certain areas, and significantly improving the drying efficiency and quality of Dendrobium officinale.

[0022] Example

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problems of existing drying devices that easily cause material to clump together when processing Dendrobium officinale with high moisture content, making it difficult for heat to penetrate, thus doubling the drying time, increasing energy consumption, and reducing polysaccharide content and efficacy. The overall idea is as follows: A drum-type drying device for processing Dendrobium officinale includes a heating cylinder 1 for providing a drying thermal environment. The heating cylinder 1 is a cylindrical hollow structure with closed ends. Two supports 2 are symmetrically fixedly installed at the lower end of the heating cylinder 1 along its axis. The supports 2 are welded and fixed to the outer wall of the heating cylinder 1 to ensure support stability. An openable feeding plate 3 is hinged to the side wall of the heating cylinder 1 near its end. The edge of the feeding plate 3 is connected to the side wall of the heating cylinder 1 by a hinge. When closed, it can seal the feeding port of the heating cylinder 1. A drive motor 4 is fixedly installed at the center of the side wall of the heating cylinder 1 away from the feeding plate 3. The output end of the drive motor 4 is along the heating cylinder 1. A rotating shaft 5 is extended and fixedly installed along the axial direction. The end of the rotating shaft 5 away from the drive motor 4 is rotatably installed on the corresponding position of the inner side wall of the heating cylinder 1 through a bearing, so that the rotating shaft 5 can rotate stably around its own axis. At least two side rods 6 are fixedly installed at intervals along the length direction of the side wall of the rotating shaft 5. The side rods 6 are perpendicular to the rotating shaft 5 and extend outward. A long strip 10 is fixedly installed on the side wall of each side rod 6 away from the rotating shaft 5. The length direction of the side strip 10 is consistent with the length direction of the side rod 6. A tamping strip 11 is fixedly installed at intervals along the length direction of the side wall of the side strip 10 away from the side rod 6. The tamping strip 11 is set perpendicular to the side strip 10. This structure enables the device to be stably placed through the bracket 2. The feeding plate 3 facilitates the feeding of materials and the sealing of the device. The drive motor 4 drives the rotating shaft 5, side rods 6, side strips 10 and tamping strips 11 to rotate synchronously, so that the tamping strips 11 can turn over the materials in the heating cylinder 1, providing a basis for the uniform heating of the materials.

[0024] A first inner groove 7 is formed along the length of the side wall of the side rod 6 away from the rotating shaft 5. The first inner groove 7 is a long strip-shaped groove with its opening facing the side bar 10. A discharge port 8 is formed through the side wall of the side rod 6 near its lower end. The discharge port 8 is a long strip-shaped through hole with its length adapted to the length of the first inner groove 7. The upper edge of the discharge port 8 is connected to the lower groove wall of the first inner groove 7, so that the material in the first inner groove 7 can flow directly into the discharge port 8. This structure realizes the temporary containment of material through the first inner groove 7. The connection design between the discharge port 8 and the first inner groove 7 allows the contained material to be discharged in a directional manner, avoiding the accumulation of material at the side rod 6.

[0025] Inside the discharge port 8, there are equidistantly fixed dispersing teeth 9 along its length. The dispersing teeth 9 are long strip-shaped rods whose length direction is consistent with the width direction of the discharge port 8. The two ends of the dispersing teeth 9 are fixedly connected to the two side walls of the discharge port 8 respectively. A gap is formed between adjacent dispersing teeth 9 to allow material to pass through. This structure separates the material in the discharge port 8 through the equidistantly distributed dispersing teeth 9, so that the clumps of Dendrobium officinale are broken up when passing through the gaps, ensuring the dispersion of the discharged material.

[0026] The side strip 10 has a second inner groove 12 along its length. The second inner groove 12 is a long strip-shaped groove that penetrates the side wall of the side strip 10 away from the side rod 6. The lower end of the side strip 10 has multiple discharge ports 13 spaced apart along its length. Each discharge port 13 is a circular or square through hole, and all discharge ports 13 are connected to the bottom wall of the second inner groove 12 to form a material flow channel. This structure receives the material shoveled in by the tamping bar 11 through the second inner groove 12, and the discharge ports 13 realize the uniform discharge of the material in the second inner groove 12, ensuring the orderly flow of material.

[0027] A first guide strip 14 is fixedly installed inside the second inner tank 12 along its length. The first guide strip 14 is a long strip-shaped plate adapted to the length of the second inner tank 12. Its two side edges are fixedly connected to the two side walls of the second inner tank 12, and the first guide strip 14 is centrally located along the width of the second inner tank 12. This structure guides the material in the second inner tank 12 through the first guide strip 14, preventing the material from accumulating on one side of the tank and ensuring that the material is evenly distributed along the length of the tank.

[0028] The first guide bar 14 is symmetrically provided with guide grooves 15 along its length. The guide grooves 15 are V-shaped or U-shaped grooves. The symmetrically distributed guide grooves 15 are arranged with the center line of the first guide bar 14 as the axis of symmetry, and the spacing between adjacent guide grooves 15 is adapted to the spacing of the discharge port 13. This structure diverts the material on the first guide bar 14 to both sides through the symmetrical guide grooves 15, so that the material can be accurately guided to the corresponding discharge port 13 below, thereby improving the uniformity of material discharge.

[0029] A second guide strip 16 is fixedly installed inside the second inner tank 12 along its length. The second guide strip 16 has the same structure and length as the first guide strip 14. Its two side edges are fixedly connected to the two side walls of the second inner tank 12. The second guide strip 16 is located directly below the first guide strip 14, with a distance of 5-10cm between them. This structure receives the material diverted by the first guide strip 14 through the second guide strip 16, provides secondary guidance for the material, prolongs the residence time of the material in the second inner tank 12, and improves the contact effect between the material and the thermal environment.

[0030] To address the problems existing in the prior art, this utility model provides a drum-type drying device for processing Dendrobium officinale. This device, through the synergistic action of the tamping strip, the first guide strip, the second guide strip, and the dispersing teeth, enables Dendrobium officinale to form an orderly flow, dispersion, and circulation within the heating drum. This significantly increases the contact area between Dendrobium officinale and the thermal environment inside the heating drum, effectively avoiding uneven drying in certain areas and significantly improving the drying efficiency and quality of Dendrobium officinale.

[0031] Working principle:

[0032] When in use, the feeding plate 3 can be opened, and then Dendrobium officinale can be put into the heating cylinder 1. Then, the drive motor 4 can be started. Under the action of the drive motor 4, the rotating shaft 5 will be rotated, and the rotating shaft 5 will drive the side rod 6 to rotate. Under the rotation of the side rod 6, the side strip 10 will rotate. At this time, the tamping strip 11 will first scoop Dendrobium officinale into the guide groove 15. After passing through the channel of the guide groove 15, Dendrobium officinale will fall onto the second guide strip 16. Then, after being guided by the second guide strip 16, it will be discharged from the discharge port 13. Then, after being broken up by the dispersing teeth 9, it will enter the stirring cycle. Dendrobium officinale increases the heating area by repeatedly rolling inside the heating cylinder 1, thereby improving the drying efficiency.

[0033] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
