Description

Technical Field

[0001] This utility model relates to the field of drying equipment, and in particular to a traditional Chinese medicine drying machine. Background Technology

[0002] Traditional Chinese medicine (TCM), as an important part of China's traditional medicine, has a history of thousands of years. It has unique advantages in the prevention and treatment of diseases and has received increasing attention worldwide in recent years. With the improvement of people's health awareness and the growth of demand for natural medicines, the TCM market is showing a rapid development trend. In order to meet market demand and ensure the quality of medicinal materials, the processing technology of TCM is particularly important. Among them, drying is one of the key steps to preserve and improve the quality of medicinal materials.

[0003] Traditional methods of drying Chinese medicinal herbs mainly include natural air drying and fire-heated drying. With the advancement of technology, various modern drying equipment and technologies have emerged. They use electric heating or steam heating to generate hot air, which circulates in a closed space to achieve a fast and uniform drying effect. However, some operators, in order to dry more herbs at once, cause the herbs to pile up when laid out, resulting in incomplete drying. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that Chinese medicinal materials tend to pile up during the laying process, resulting in incomplete drying, and proposes a Chinese medicinal material drying machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A traditional Chinese medicine drying machine includes a housing and an isolation door. The isolation door is rotatably mounted on the housing. A motor is fixedly mounted on the housing. The output end of the motor passes through the housing and is fixedly mounted on a first transmission block. A support member is rotatably mounted inside the housing. A support mesh plate for supporting the traditional Chinese medicine to be dried is mounted on the support member. A second transmission block is fixedly mounted on one end of the support member near the first transmission block. The machine also includes a horizontal plate, which is fixedly mounted inside the housing to support the support member. The first transmission block and the second transmission block each have equally spaced helical teeth on their opposing surfaces and are connected by the meshing of the helical teeth.

[0007] To satisfy the purpose of the support component moving up and down in the box to vibrate the medicinal materials, causing the medicinal materials to oscillate on the support mesh plate and reducing the adhesion of the medicinal materials, preferably, the support component includes a support shaft and a bushing rotatably installed on the bottom surface of the box. A limit plate is fixedly installed on one end of the support shaft located inside the bushing. A spring is sleeved on the support shaft, and the two ends of the spring are respectively fixed to the limit plate and the bottom surface of the bushing.

[0008] To prevent unnecessary lateral movement or tilting during rotation, the inner wall of the bushing is provided with symmetrically arranged sliding grooves, and the limiting plate has sliding pins that are adapted to the sliding grooves.

[0009] To achieve height adjustment and fixation of the support mesh plate, the support mesh plate further includes a connecting part coaxially arranged with the support shaft. The connecting part has symmetrically arranged connecting holes, and the support shaft has equidistant adjusting holes. The support mesh plate is fixed by locking bolts that engage with any adjusting hole on the support shaft.

[0010] To prevent the accumulation of dregs or other impurities from affecting air circulation and to ensure uniform heating of the medicinal materials and effective removal of moisture, the bushing is further provided with an air outlet and an air outlet hose adapted to the air outlet. The end of the air outlet hose away from the bushing is fixed to the support mesh plate. The bushing is provided with an air inlet, and a one-way valve is installed in both the air outlet and the air inlet.

[0011] To accelerate the evaporation of moisture and improve the overall drying efficiency, the exhaust hose is further provided with equidistant turbulence holes at one end of the support mesh plate.

[0012] To maintain stable air pressure inside the enclosure and avoid problems caused by unbalanced airflow, a ventilation system is further included. The ventilation system includes an air inlet and an exhaust outlet installed on the enclosure to maintain suitable airflow inside the enclosure, and a filter plate installed inside the air inlet to isolate external pollutants.

[0013] Compared with the prior art, this utility model provides a traditional Chinese medicine drying machine, which has the following features:

[0014] Beneficial effects:

[0015] 1. This Chinese herbal medicine dryer uses a motor to drive the first transmission block to rotate in both directions, changing the motion state of the second transmission block. When the first transmission block rotates in the forward direction, the second transmission block drives the support component to rotate together, thus ensuring that the herbs are fully heated and evenly heated during the drying process. When the first transmission block rotates in the reverse direction, the helical teeth on the first transmission block press against the helical teeth on the second transmission block, causing the second transmission block to drive the support component to move up and down inside the chamber, vibrating the herbs and causing them to oscillate on the support mesh, reducing the possibility of herbs sticking together. At the same time, the residual heat inside the chamber is used to make the herbs go from a relatively ideal level of dryness to an ideal level of dryness, thereby improving drying efficiency and quality.

[0016] 2. This Chinese herbal medicine dryer allows the operator to flexibly adjust the height of the support mesh plate according to the type, volume, and drying requirements of the herbs, ensuring that the herbs are evenly spread and avoiding excessive stacking that would affect the drying effect. Once the support mesh plate is adjusted to the appropriate position and fixed with locking bolts, it can effectively ensure that the support mesh plate remains stable throughout the drying process, thereby improving drying efficiency and quality. Furthermore, since the height of the support mesh plate can be adjusted as needed, the operator can check the condition of the herbs at any time during the drying process and make corresponding adjustments based on the actual situation (such as increasing or decreasing the number of layers).

[0017] 3. In this Chinese medicine dryer, when the support moves up and down in the box, it vibrates the medicinal materials, causing them to oscillate on the support mesh plate. Due to the presence of air outlets and air inlets, the air inside the bushing is constantly renewed and squeezed into the air outlet hose, directly acting on the medicinal materials. This prevents the accumulation of dregs or other impurities from affecting air circulation, ensuring uniform heating of the medicinal materials and effective removal of moisture.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example:

[0026] Reference Figures 1-4 A traditional Chinese medicine dryer includes a housing 1 and an isolation door 2. The housing 1 serves as the outer shell of the dryer, providing a sealed space to prevent outside air from entering and affecting the drying effect, while effectively retaining internal heat. The isolation door 2 is rotatably mounted on the housing 1, facilitating the loading and unloading of the traditional Chinese medicine to be dried, and also serves as a seal to ensure controllable temperature and humidity during the drying process. A motor 3 is fixedly mounted on the housing 1, with the output end of the motor 3 passing through the housing 1 and fixedly mounted on a first transmission block 6. A support member 4 is rotatably mounted inside the housing 1, and a support mesh plate 5 for supporting the traditional Chinese medicine to be dried is mounted on the support member 4. The support member 4 is close to the first transmission block 6. A second transmission block 7 is fixedly installed at one end of the transmission block 6, and a horizontal plate 8 is also included. It is fixedly installed inside the box 1 to support the support member 4, ensuring its stability and balance, while allowing the support member 4 to rotate freely. The first transmission block 6 and the second transmission block 7 have equally spaced helical teeth 9 on their opposite surfaces, and are connected by meshing helical teeth 9. The motor 3 drives the first transmission block 6 to rotate, and through the meshing of the helical teeth 9, it drives the second transmission block 7 and the connected support member 4 to rotate together. The support mesh plate 5 on the support member 4 rotates accordingly, so that the Chinese medicinal materials placed on it can receive sufficient heat energy during the drying process, thereby achieving the purpose of uniform heating.

[0027] It should be noted that a temperature and humidity sensor panel controller is added to cabinet 1 to achieve precise control of the drying environment, thereby further improving drying quality and efficiency.

[0028] When using this Chinese herbal medicine dryer, the operator first needs to open the isolation door 2, which is mounted on the rotating housing 1, and evenly spread the Chinese herbal medicines to be dried on the support mesh plate 5, ensuring that the medicines are not stacked too high to avoid affecting rotation and heat distribution. After confirming that the medicines are loaded, close and lock the isolation door 2 to ensure the airtightness of the housing 1. Set appropriate parameters such as temperature, humidity, and time through the panel controller to ensure that the optimal drying conditions for the specific Chinese herbal medicines are met. Once all preparations are complete, start the motor 3. The motor 3 rotates clockwise, driving the first transmission block 6 to rotate. The helical teeth 9 on the first transmission block 6 and the second transmission block 7 mesh with each other. As the first transmission block 6 rotates, the second transmission block 7 drives the support member 4 to rotate as well. The rotation of the support member 4 causes the installed... The supporting mesh plate 5 also rotates, allowing the medicinal materials to be fully heated during the drying process and ensuring uniform heating. When the predetermined drying time is reached and / or the medicinal materials have reached a relatively ideal degree of dryness, the drive motor 3 rotates counterclockwise to drive the first transmission block 6. The helical teeth 9 on the first transmission block 6 press against the helical teeth 9 on the second transmission block 7, causing the second transmission block 7 to drive the support member 4 to move up and down inside the box 1, generating vibrations in the medicinal materials. This causes the medicinal materials to vibrate on the supporting mesh plate 5, reducing the possibility of the medicinal materials sticking together. At the same time, the residual heat inside the box 1 is used to change the medicinal materials from a relatively ideal degree of dryness to an ideal degree of dryness. After cooling, the isolation door 2 can be safely opened, and the dried Chinese medicinal materials can be carefully removed from the supporting mesh plate 5 for further processing or packaging.

[0029] The support component 4 includes a support shaft 401, which is the core part of the entire support system. It not only supports the support mesh plate 5 for placing Chinese medicinal materials, but also achieves rotation by meshing with the first transmission block 6 through the second transmission block 7 at one end. The bushing 402, which is rotatably installed on the bottom surface of the housing 1, provides a stable rotation fulcrum for the support shaft 401. The bushing 402 ensures that the support shaft 401 can rotate smoothly while maintaining its verticality and stability. A limit plate 403 is fixedly installed on one end of the support shaft 401 inside the bushing 402 to prevent the support shaft 401 from sliding out of the bushing 402. A spring 404 is sleeved on the support shaft 401, and the two ends of the spring 404 are fixed to the limit plate 403 and the bottom surface of the bushing 402, respectively.

[0030] When the support shaft 401 is subjected to external impact or vibration, the spring 404 can absorb this energy, reduce the impact on the transmission system, and protect the motor 3 and other mechanical parts. The spring 404 can also allow the support shaft 401 to float up and down within a certain range, so that the support 4 can move up and down in the box 1 to generate vibration on the medicinal materials, so that the medicinal materials can vibrate on the support mesh plate 5 and reduce the adhesion of the medicinal materials.

[0031] The inner wall of the bushing 402 is provided with symmetrically arranged sliding grooves 405, and the limiting plate 403 has sliding pins 406 that are adapted to the sliding grooves 405.

[0032] The cooperation of the slide groove 405 and the sliding pin 406 can ensure the linear movement of the limit plate 403 and the support shaft 401 in the axial direction, preventing unnecessary lateral movement or tilting during rotation. At the same time, through the precise matching of the slide groove 405 and the sliding pin 406, the maximum distance of the support shaft 401 floating in the axial direction can be effectively limited, avoiding the failure of the connection between the transmission components due to excessive displacement.

[0033] The support mesh plate 5 has a connecting part 501 coaxially arranged with the support shaft 401. The connecting part 501 serves as a connecting bridge between the support mesh plate 5 and the support shaft 401, ensuring a tight fit between the two. The connecting part 501 has symmetrically arranged connecting holes 502, and the support shaft 401 has equidistantly arranged adjustment holes 407. The support mesh plate 5 is fixed by locking bolts to any adjustment hole 407 on the support shaft 401, thereby realizing the height adjustment and fixation of the support mesh plate 5.

[0034] The operator can flexibly adjust the height of the support mesh plate 5 according to the type, volume and drying requirements of the medicinal materials to ensure that the medicinal materials are evenly spread and avoid stacking too high, which would affect the drying effect. Once the support mesh plate 5 is adjusted to the appropriate position and fixed with locking bolts, it can effectively ensure that the support mesh plate 5 remains stable throughout the drying process, thereby improving drying efficiency and quality. Furthermore, since the height of the support mesh plate 5 can be adjusted as needed, the operator can check the condition of the medicinal materials at any time during the drying process and make corresponding adjustments (such as increasing or decreasing the number of layers) according to the actual situation.

[0035] The bushing 402 is provided with an air outlet 408 and an air outlet hose 409 adapted to the air outlet 408. The end of the air outlet hose 409 away from the bushing 402 is fixed on the support mesh plate 5. The bushing 402 is provided with an air inlet 411. Both the air outlet 408 and the air inlet 411 are equipped with one-way valves.

[0036] When the support 4 moves up and down inside the housing 1, it vibrates the medicinal materials, causing them to oscillate on the support mesh plate 5. Due to the presence of the air outlet 408 and the air inlet 411, the air inside the bushing 402 is constantly renewed and squeezed into the air outlet hose 409, directly acting on the medicinal materials. This prevents the accumulation of dregs or other impurities from affecting air circulation, ensuring uniform heating of the medicinal materials and effective removal of moisture.

[0037] It should be noted that the one-way valve ensures that the gas can only flow in the set direction, that is, it enters from the inlet 411, passes through the bushing 402 and is discharged from the outlet 408, forming a circulation loop.

[0038] Furthermore, the air outlet hose 409 has equidistant turbulence holes 410 at one end on the support mesh plate 5.

[0039] The presence of the turbulence hole 410 allows the hot and humid air discharged through the air outlet hose 409 to spread more evenly above the support mesh plate 5, rather than being concentrated at one point. This helps to form a more uniform airflow throughout the entire support mesh plate 5, ensuring that all parts of the medicinal material receive good ventilation and drying. Since the airflow is dispersed into multiple small streams, the chance of contact with the surface of the medicinal material is increased, thereby accelerating the rate of moisture evaporation and improving the overall drying efficiency.

[0040] The Chinese herbal medicine dryer also includes a ventilation system, which includes an air inlet 10 and an exhaust outlet 11 installed on the housing 1. The air inlet 10 serves as a channel for fresh air to enter the drying chamber, providing the necessary oxygen for the drying process, maintaining suitable temperature and humidity conditions, and promoting uniform drying of the medicinal materials. In conjunction with the exhaust outlet 11, it maintains stable air pressure inside the housing 1, avoiding problems caused by unbalanced airflow, and maintaining suitable airflow inside the housing 1. The exhaust outlet 11 is also installed on the housing 1, but is usually located at the top or side to facilitate the discharge of hot and humid air, prevent moisture accumulation from affecting the drying effect, and a filter plate 12 is installed inside the air inlet 10 to isolate external pollutants, protect the medicinal materials from contamination, and ensure the quality of the medicinal materials.

[0041] Before drying begins, fresh air introduced through air inlet 10 pre-adjusts the environmental conditions inside chamber 1, ensuring optimal conditions from the outset. Throughout the drying process, the ventilation system ensures a continuous supply of fresh air and effective removal of moisture from chamber 1, maintaining suitable temperature and humidity levels and improving drying efficiency. The presence of filter plate 12 effectively isolates external pollutants, ensuring that the medicinal materials are not affected by external factors during the entire drying process, thus guaranteeing the quality of the medicinal materials. After drying, air inlet 10 continues to introduce fresh air to help cool the chamber, while exhaust port 11 ensures that any remaining moisture is completely removed, facilitating subsequent operations such as unloading the medicinal materials.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
