Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine processing technology, specifically a drying oven for traditional Chinese medicine processing. Background Technology

[0002] The drying oven for traditional Chinese medicine (TCM) processing is a key piece of equipment in the production process of medicinal materials, directly affecting the quality of the finished product, the stability of its medicinal efficacy, and production efficiency. A built-in fan evenly distributes hot air generated by the heating elements into the drying chamber, forming a directional circulating airflow. A typical application is the CT-C series hot air circulating oven, which uses a low-noise, high-temperature resistant axial flow fan, achieving a thermal efficiency of up to 45%, more than 10 times higher than traditional drying rooms. It is suitable for the rapid dehydration of root and rhizome medicinal materials such as ginseng and astragalus.

[0003] In existing technology, such as the drying box for processing traditional Chinese medicine decoction pieces disclosed in announcement number CN208012253U, a box body is included. Multiple placement plates are arranged inside the box body. A first groove is formed on the inner wall of the top of the box body. A gear groove is formed on one side of the inner wall of the first groove. A first rotating rod is rotatably installed in the first groove, and a first gear is fixedly sleeved on the first rotating rod. A first rotary motor is fixedly installed on the inner wall of the top of the box body. The output shaft of the first rotary motor extends into the gear groove and is welded with a second gear, which meshes with the first gear. A first drying lamp is fixedly installed at the bottom of the first rotating rod. A second groove is formed on the inner wall of the bottom of the box body, and a second rotating rod is rotatably installed in the second groove. This allows for the rotation of the first and second drying lamps, achieving the purpose of uniformly drying the traditional Chinese medicine. It has a simple structure and is easy to install.

[0004] The existing drying oven can rotate the first and second drying lamps to achieve the purpose of uniform drying of Chinese medicine. It has a simple structure, but it directly places the Chinese medicine inside the cylindrical box for heating and drying. Stacked Chinese medicine cannot be fully heated and dried, making it difficult to cover all the medicine during the heating process, resulting in poor practicality. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given that the existing drying ovens in the above-mentioned technologies directly place Chinese medicinal materials inside the cylindrical box for heating and drying, the stacked Chinese medicinal materials cannot be fully heated and dried, making it difficult to cover all the medicinal materials during the heating process, resulting in poor practicality.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A drying oven for processing traditional Chinese medicine includes a drying oven shell, with two protective doors hinged to the outer wall of the drying oven shell. A drive assembly for driving the device is provided on one side of the drying oven shell, and a drying assembly for drying traditional Chinese medicine is provided at the upper end of the drying oven shell.

[0009] The drive assembly includes a drive motor, which is fixed to one side of the drying chamber shell by bolts. The drive motor's power output shaft is fixed with a drive pulley. A belt is connected to one side of the drive pulley, and a driven pulley is connected to the right side of the belt. The driven pulley is connected to an inner drying chamber housed inside the drying chamber shell via a rotating shaft.

[0010] As a further improvement of this utility model: the outer surface of the drying inner box is provided with a number of exhaust holes, and the outer wall of the drying inner box is hinged with a door panel.

[0011] As a further improvement of this utility model: the inner wall of the drying oven shell is fixed with an insulated inner shell.

[0012] As a further embodiment of this utility model: the drying assembly includes a circulating air pump, which is fixed to the upper end of the drying chamber shell by bolts, and the input end of the circulating air pump is connected to a filter.

[0013] As a further improvement of this utility model: the output end of the circulating air pump is connected to a conveying pipe, and the end of the conveying pipe is connected to a heating element.

[0014] As a further improvement of this utility model: a heating wire is installed inside the heating element, and a connector is connected to one end of the heating element.

[0015] As a further embodiment of this utility model: the outer surface of the connector is fitted with a fixed bearing embedded in the inner wall of the drying oven shell, and both ends of the connector are connected to auxiliary pipes, and the outer surface of the auxiliary pipes is provided with several hot air holes.

[0016] As a further improvement of this utility model: a filter screen is installed vertically inside the filter element, and both ends of the filter screen are fixed with clips that are inserted and connected to the filter element.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model uses a circulating air pump to extract air from the outer shell of the drying chamber, which is then sent to the heating element through a conveying pipe. The heating wire can heat the air when activated. The heated air enters the interior of the connecting part and is sprayed out through the hot air hole on the auxiliary pipe, thereby drying the Chinese medicine in the drying chamber.

[0019] 2. This utility model uses a drive motor to drive the active pulley to rotate, which, in conjunction with the belt, synchronously drives the driven pulley to rotate, thereby causing the inner drying chamber to rotate. This allows the Chinese medicine inside to tumble, ensuring that the Chinese medicine at the bottom can fully contact the hot air, thus improving the drying effect.

[0020] 3. With the assistance of the auxiliary tube, this utility model can achieve the function of stirring Chinese medicine, and the fixed bearing can prevent the connecting parts from rotating when the inner drying box rotates. The heat-insulating inner shell set inside the outer shell of the drying box can play a certain heat preservation role.

[0021] 4. This utility model recirculates hot air by drawing it out again by a circulating air pump. When the hot air passes through the filter element, the filter screen can filter impurities in the air, realizing the utilization of waste heat. The filter screen can be disassembled by the clips on the filter screen. Attached Figure Description

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0031] Example 1

[0032] Please see Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a drying box for processing traditional Chinese medicine, including a drying box shell 1. Two protective doors 2 are hinged to the outer wall of the drying box shell 1. A drive assembly for driving the device is provided on one side of the drying box shell 1, and a drying assembly for drying traditional Chinese medicine is provided at the upper end of the drying box shell 1.

[0033] The drive assembly includes a drive motor 3, which is fixed to one side of the drying chamber shell 1 by bolts. The power output shaft of the drive motor 3 is fixed with a drive pulley 31. A belt 32 is connected to one side of the drive pulley 31, and a driven pulley 33 is connected to the right side of the belt 32. The inner drying chamber 34, which is placed inside the drying chamber shell 1, is connected to the driven pulley 33 through a rotating shaft.

[0034] Specifically, the outer surface of the drying inner chamber 34 is provided with several exhaust holes 35, and the outer wall of the drying inner chamber 34 is hinged with a door panel 36.

[0035] Furthermore, the Chinese medicine that needs to be dried is poured into the drying chamber 34, and then the door panel 36 and the protective door 2 are closed to provide protection.

[0036] Specifically, an insulated inner shell 4 is fixed to the inner wall of the drying oven outer shell 1.

[0037] Furthermore, the heat-insulating inner shell 4 installed inside the outer shell 1 of the drying oven can play a certain role in heat preservation.

[0038] In use, place the outer shell 1 of the drying chamber in a suitable position, open the protective door 2 on the side wall of the outer shell 1, and then open the door panel 36 on the inner drying chamber 34. Pour the Chinese medicine to be dried into the inner drying chamber 34, and close the door panel 36 and the protective door 2. During the drying process, the drive motor 3 drives the active pulley 31 to rotate. With the cooperation of the belt 32, the driven pulley 33 is driven to rotate synchronously, which in turn drives the inner drying chamber 34 to rotate. This allows the Chinese medicine inside to tumble, so that the Chinese medicine at the bottom can fully contact the hot air, thereby improving the drying effect.

[0039] In summary, when in use, this Chinese medicine processing drying box can drive the inner drying chamber 34 to rotate, which can tumble the Chinese medicine inside, allowing the Chinese medicine at the bottom to fully contact the hot air, improving the drying effect. It can also stir the Chinese medicine, further improving the drying efficiency.

[0040] Example 2

[0041] Please see Figures 1-5 This is the second embodiment of the present utility model.
