[0026] A drying device for processing fresh Chinese medicinal materials includes a drying chamber 1 and an air circulation assembly. A protective door 2 is rotatably mounted on one side of the drying chamber 1. The protective door 2 is opened to allow the placement of medicinal materials or their removal after drying. The drying chamber 1 contains multiple placement trays 3 for holding the medicinal materials to be dried. Insertion blocks 4 are connected to both sides of each placement tray 3. Multiple insertion slots 5 are symmetrically formed on both sides of the drying chamber 1 for inserting the insertion blocks 4. The insertion slots 5 are evenly distributed on both sides of the drying chamber 1. The spacing between the insertion blocks 4 and the upper and lower placement trays 3 can be determined according to the different medicinal materials in the trays 3, allowing the insertion blocks 4 to be inserted into the corresponding insertion slots 5 at the desired height. This adapts to the drying of different medicinal materials, improving the practicality of the device. Furthermore, the number of placement trays 3 can be adjusted at any time, increasing the working efficiency of the drying device. To ensure relative stability between the placement tray 3 and the drying chamber 1, a fixing component is provided on the front surface of both the placement tray 3 and the insertion block 4. This fixing component ensures that the placement tray 3 is stably placed inside the drying chamber 1, guaranteeing the orderly progress of the drying process. A vacuum pump 8 is fixedly connected to the rear end of the drying chamber 1, and a hot air blower 12 is installed on the top outer side of the drying chamber 1. The output end of the hot air blower 12 is connected to the air inlet hood 13 inside the drying chamber 1. When drying medicinal materials, the materials to be dried are first placed on the placement tray 3, then the protective door 2 is closed, and then the vacuum pump 8 is turned on. The air pressure inside the drying chamber 1 decreases, allowing the moisture in the medicinal materials to evaporate under low-temperature conditions. Then, the hot air blower 12 is turned on, allowing hot air to enter the drying chamber 1 through the air inlet hood 13. The pressure inside the drying chamber 1 causes the moisture in the medicinal materials to evaporate under low-temperature conditions, enabling the medicinal materials to be dried at low temperatures. This prevents high temperatures from affecting the efficacy of the medicinal materials, making it convenient to use and highly practical.

[0027] In the above embodiment, the air circulation assembly includes a return pipe 9, a dryer, and an air outlet pipe 11. The input end of the return pipe 9 is connected to the lower part of the drying chamber 1, and the output end of the return pipe 9 is connected to the dryer. The output end of the dryer is connected to the hot air blower 12 through the air outlet pipe 11. The dryer is fixedly installed on the drying chamber 1. When drying the Chinese medicinal materials in the drying chamber 1, the humid hot air enters the dryer through the return pipe 9 for drying. The structure and working principle of the dryer can be found in the prior art. Afterward, the dried hot air enters the hot air blower 12 through the air outlet pipe 11 for recycling, which allows the hot air to be recycled, reduces the waste of heat energy, and is convenient and practical.

[0028] To improve drying efficiency, preferably, a partition net 301 is provided at the bottom of the placement tray 3, and handles 302 are provided at the left and right positions on the upper surface of the placement tray 3, so that the placement tray 3 can be lifted easily by means of the handles 302.

[0029] In this embodiment, the fixing component includes a connecting block 601 shared by the front surfaces of the placement plate 3 and the insertion block 4. The connecting block 601 has movable grooves 602 on both its left and right sides. A fixing rod 603 is slidably disposed within the movable groove 602. One end of a connecting spring 604 is fixedly connected to the inner wall of the movable groove 602, and the other end of the connecting spring 604 is fixedly connected to the fixing rod 603. One end of the fixing rod 603 extends out of the connecting block 601. The inner wall of the insertion slot 5 has a connecting hole 605 that engages with the fixing rod 603. One end of a movable rod 606 is fixedly connected to the upper surface of the fixing rod 603, and the other end of the movable rod 606 extends out of the connecting block 601 and is fixedly connected to a movable rod 606. The upper surface of the connecting block 601 is provided with a moving groove 608 for the moving rod 606 to move. When adjusting the relative height of the placement tray 3, the moving plate 607 can be pulled first. The moving plate 607 drives the fixed rod 603 to move in the moving groove 602 through the moving rod 606. At this time, the fixed rod 603 disengages from the connecting hole 605, thereby releasing the fixation of the placement tray 3. Then, the placement tray 3 can be moved out by the cooperation of the insertion block 4 and the insertion groove 5 and inserted into the insertion groove 5 of the corresponding height. By inserting the fixed rod 603 into the corresponding connecting hole 605, the relative height of the placement tray 3 can be adjusted. By setting multiple insertion grooves 5, a corresponding number of placement trays 3 can also be used as needed.

[0030] To facilitate the movement of this device, preferably, a support assembly 7 is provided at the bottom of the drying oven 1.

[0031] The support assembly 7 includes a threaded post 701, a rotating sleeve 702, a base plate 703, and casters 704. One end of the threaded post 701 is connected to the bottom of the drying chamber 1, and the other end of the threaded post 701 is inserted into the rotating sleeve 702 and screwed into it. The rotating sleeve 702 is rotatably connected to the base plate 703. The casters 704 are connected to the bottom of the base plate 703. A self-locking assembly 705 is provided on the casters 704. When the device needs to be placed on an uneven ground, the corresponding side base plate 703 can be fixed, and then the side rotating sleeve 702 can be rotated to adjust the distance between the side base plate 703 and the bottom surface of the drying chamber 1, so that the drying chamber 1 can be placed stably and horizontally on the bottom surface. The casters 704 facilitate the movement of the drying chamber 1 by the operator. The self-locking assembly 705 locks the casters 704 after the drying chamber 1 is moved into place, preventing the drying chamber 1 from moving freely.

[0032] Preferably, the air inlet hood 13 is equipped with a filter screen inside to filter impurities in the air, preventing impurities from adhering to the surface of the Chinese medicinal materials, thereby greatly improving the quality of the medicinal materials.

[0033] The drying device for processing fresh Chinese medicinal materials provided in this application operates as follows: The Chinese medicinal materials to be dried are placed in a placement tray 3. The tray 3 is lifted using handles 302 on both sides, allowing the insertion blocks 4 on both sides to be inserted into the corresponding insertion slots 5. The relative height of the placement tray 3 is adjusted by inserting the fixing rod 603 into the corresponding connecting hole 605. Then, the protective door 2 is closed, and the vacuum pump 8 is turned on. The air pressure inside the drying chamber 1 decreases, allowing the moisture in the medicinal materials to evaporate at low temperatures. Then, the hot air fan 12 is turned on, allowing hot air to enter the drying chamber 1 through the air inlet hood 13. The pressure inside the drying chamber 1 causes the moisture in the medicinal materials to evaporate at low temperatures, allowing the Chinese medicinal materials to be dried at low temperatures. This prevents high temperatures from affecting the efficacy of the medicinal materials, making it convenient to use and highly practical. After drying, the movable plate 607 can be pulled. The movable plate 607 drives the fixed rod 603 to move in the movable groove 602 through the movable rod 606. At this time, the fixed rod 603 disengages from the connecting hole 605, thereby releasing the fixation of the placement tray 3. Then, the placement tray 3 can be moved out through the cooperation of the plug block 4 and the plug slot 5.
