[0002] In the production and processing of traditional Chinese medicine, sterilization is a key step to ensure the quality of Chinese medicine, extend its shelf life, and avoid the influence of microbial contamination on its efficacy. Among these technologies, low-temperature plasma sterilization technology has become an ideal direction in the field of Chinese medicine sterilization due to its advantages such as operating at room temperature, high sterilization efficiency, and no residue.

[0003] The inventors have found that at least the following problems remain unsolved in the existing technology: existing sterilization tanks generally lack a mechanism to disturb medicinal materials, causing Chinese medicinal materials to accumulate statically during sterilization, resulting in uneven contact between the low-temperature plasma gas and the medicinal materials, large differences in gas concentration in local areas, and unstable sterilization effect. Of course, sterilization kettles with agitation mechanisms are also produced on the market, but their effects are limited. During the agitation process, the medicinal herbs at the bottom cannot effectively come into contact with the low-temperature gas, resulting in low gas utilization and affecting the sterilization effect and efficiency of the medicinal herbs.

[0004] Therefore, we propose a low-temperature plasma sterilization autoclave for the sterilization process of traditional Chinese medicine, which can solve the above problems. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figures 1 to 4 A low-temperature plasma sterilization autoclave for sterilizing traditional Chinese medicine includes an autoclave body 1. An agitation tube 11 is installed inside the autoclave body 1 to agitate the traditional Chinese medicine materials inside. Equidistant air outlets 34 are provided on the outer side of the agitation tube 11 for uniform emission of low-temperature gas. A driving mechanism is installed above the autoclave body 1 to drive the agitation tube 11 to rotate. A circulation mechanism is installed inside the top of the autoclave body 1 for circulating the low-temperature gas. The driving mechanism includes a control component for automatically controlling the operation of the circulation mechanism.

[0018] The herbal medicines are agitated by a disturbance tube 11 inside the vessel body 1, while the vent 34 on the outside of the disturbance tube 11 evenly discharges low-temperature plasma gas into the vessel, ensuring full contact between the gas and the herbs. A drive mechanism above the vessel body 1 provides rotational power to the disturbance tube 11, continuously agitating the herbs. A circulation mechanism at the top of the vessel body 1 circulates the low-temperature gas within the vessel, reducing gas waste and improving sterilization uniformity. Simultaneously, the control components built into the drive mechanism automatically trigger the circulation mechanism, eliminating the need for manual operation and achieving automated, coordinated sterilization.

[0019] Furthermore, the driving mechanism includes a connecting pipe 16 for mounting the disturbance pipe 11 and a drive motor 17 for driving the connecting pipe 16 to rotate. The disturbance pipe 11 is equidistantly mounted on the outer side of the lower end of the connecting pipe 16. The shaft end of the drive motor 17 is fixedly connected to the top end of the connecting pipe 16. A bracket 18 is fixedly mounted on the upper surface of the vessel body 1, and the drive motor 17 is fixedly connected to the upper surface of the bracket 18.

[0020] When the drive motor 17 starts, its shaft end will directly drive the connecting pipe 16 to rotate. Since the disturbance pipes 11 are equidistantly installed on the outer side of the lower end of the connecting pipe 16, the rotation of the connecting pipe 16 will synchronously drive all the disturbance pipes 11 to rotate inside the vessel body 1, thereby disturbing the Chinese medicinal materials in the vessel in all directions, breaking the accumulation state of the medicinal materials, and creating conditions for the uniform action of the subsequent low-temperature gas.

[0021] Furthermore, the circulation mechanism includes a channel 21 for pumping out low-temperature gas and a gas inlet 29 opened at the upper end of the connecting pipe 16. The channel 21 is horizontally opened inside the top of the vessel body 1. A piston 23 is slidably connected inside the channel 21. A guide groove 25 is opened on one side of the channel 21. The connecting pipe 16 is rotatably connected to the inner wall of the top and bottom ends of the guide groove 25 through a sealed bearing. The guide groove 25 is connected to the connecting pipe 16 through the gas inlet 29. The connecting pipe 16 is connected to the disturbance pipe 11.

[0022] The connecting pipe 16 is rotatably connected to the inner wall of the guide groove 25 via a sealed bearing, ensuring normal rotation of the connecting pipe 16 while preventing gas leakage. When circulating cryogenic gas, the gas can enter the connecting pipe 16 through the gas inlet 29, then flow into the connected agitator pipe 11, and finally exit from the gas outlet 34. At the same time, the through groove 21 can pump out the gas by moving the piston 23, which, together with the connection between the guide groove 25 and the connecting pipe 16, establishes a circulation path for the cryogenic gas.

[0023] Furthermore, a rotating groove 2 is provided on the side of the through groove 21 away from the guide groove 25. A flywheel 22 is horizontally arranged on the inner side of the rotating groove 2. One end of the bottom side of the flywheel 22 is connected to the piston 23 via a crank connecting rod 24. An air outlet groove 26 and an air extraction groove 27 are respectively provided above and below the inner wall of the through groove 21 near the guide groove 25.

[0024] When the flywheel 22 rotates, it drives the piston 23 to reciprocate linearly within the through groove 21 via the crank connecting rod 24. When the piston 23 moves outward, it can extract the low-temperature gas at the top of the vessel through the extraction groove 27; when the piston 23 moves inward, it can force the gas through the outlet groove 26 into the guide groove 25, thereby realizing the extraction and discharge operation of the low-temperature gas and providing power for gas circulation.

[0025] Furthermore, the through groove 21 is connected to the guide groove 25 via the vent groove 26, and the through groove 21 is connected to the top of the inside of the vessel body 1 via the extraction groove 27. Both the vent groove 26 and the extraction groove 27 are equipped with one-way valves 28.

[0026] The one-way valve 28 in the outlet groove 26 only allows gas to flow from the through groove 21 to the guide groove 25, preventing gas from flowing back into the through groove 21; the one-way valve 28 in the extraction groove 27 only allows gas to flow from inside the vessel body 1 to the through groove 21, preventing gas in the through groove 21 from flowing back into the vessel body 1. Through the one-way conduction of the two one-way valves 28, it is ensured that the cryogenic gas always circulates in the direction of "inside the vessel body 1 → extraction groove 27 → through groove 21 → outlet groove 26 → guide groove 25", ensuring circulation efficiency and stability.

[0027] Furthermore, the control component includes a small pulley 31 for driving the flywheel 22 to rotate, a large pulley 32 is fixedly installed through the connecting pipe 16 near the drive motor 17, a drive rod 3 is vertically fixedly installed in the middle of the bottom side of the small pulley 31, one end of the drive rod 3 is fixedly connected to the middle of the upper surface of the flywheel 22, the drive rod 3 is rotatably connected to the inner wall of the top of the rotating groove 2 through a bearing, and the large pulley 32 is connected to the small pulley 31 through a transmission belt 33.

[0028] When the connecting pipe 16 rotates under the drive of the drive motor 17, the large pulley 32 will rotate synchronously. The large pulley 32 transmits power to the small pulley 31 through the transmission belt 33, causing the small pulley 31 to rotate accordingly. The drive rod 3 on the bottom side of the small pulley 31 is fixedly connected to the flywheel 22, and the drive rod 3 is rotatably connected to the inner wall of the top of the rotating groove 2 through a bearing. The rotation of the small pulley 31 will drive the drive rod 3 and the flywheel 22 to rotate, which in turn drives the piston 23 to move through the crank connecting rod 24, realizing the automatic start of the circulation mechanism without the need for an additional power source, and realizing the power linkage between the drive mechanism and the circulation mechanism.

[0029] Furthermore, an air inlet pipe 12 and an air outlet pipe 13 are respectively installed through the top of the inner walls on both sides of the vessel body 1, and a discharge pipe 14 is installed through the middle of the inner wall at the bottom of the vessel body 1. Valves 15 are provided inside the air inlet pipe 12, the air outlet pipe 13 and the discharge pipe 14.

[0030] The air inlet pipes 12 at the top of both sides of the vessel body 1 are used to introduce low-temperature plasma gas into the vessel, and the air outlet pipes 13 are used to discharge the gas from the vessel after sterilization. The discharge pipe 14 at the bottom is used to discharge the sterilized Chinese medicinal materials. The valves 15 inside the air inlet pipes 12, 13, and 14 can control the opening and closing of each pipe. During sterilization, the valves 15 of the air outlet pipes 13 and 14 are closed, and the valve 15 of the air inlet pipe 12 is opened to introduce gas. After sterilization, the valve 15 of the air inlet pipe 12 is closed, the valve 15 of the air outlet pipe 13 is opened to exhaust gas, and finally the valve 15 of the discharge pipe 14 is opened to discharge the medicinal materials. The orderly operation of different processes is achieved by switching the valves 15.

[0031] Furthermore, a feed pipe 19 is installed through the inner wall of the top of the vessel body 1 on the side away from the rotating groove 2, and a sealing cap 35 is detachably installed at the top of the feed pipe 19.

[0032] The feed pipe 19 at the top of the vessel body 1 provides a channel for the input of Chinese medicinal herbs. When inputting the herbs, the sealing cap 35 at the top of the feed pipe 19 can be removed, and the herbs can be poured into the vessel body 1 through the feed pipe 19. After the herbs have been input, the sealing cap 35 can be reinstalled to ensure the airtightness of the vessel body 1, prevent low-temperature gas from leaking from the feed pipe 19 during the sterilization process, and ensure the gas concentration and sterilization effect inside the vessel.

[0033] 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.
