[0002] In the process of Chinese medicine processing, in order to ensure the safety of Chinese medicine consumption and the long-term storage, the raw materials of Chinese medicine usually need to be sterilized before the production process of the medicinal materials. The sterilization methods usually used are ultraviolet sterilization or high-temperature steam sterilization. Ultraviolet sterilization has a strong effect, but its ability to penetrate objects is very weak. When sterilizing a large number of Chinese medicine raw materials, the Chinese medicine raw materials need to be laid flat and turned over. The sterilization effect is not very ideal, and the efficiency of the sterilization treatment is also low. Therefore, in order to improve the effect and efficiency of the sterilization of Chinese medicine raw materials, high-temperature steam is generally used to sterilize the medicinal materials.
[0003] However, in the prior art, conventional medicinal high-temperature steam sterilizers have dead corners when performing high-temperature steam sterilization on Chinese medicine raw materials. Some Chinese medicine raw materials cannot be fully exposed to high-temperature steam, and the sterilization is not comprehensive enough, resulting in poor effect.
[0004] In summary, there is currently a need for a high-temperature sterilization equipment for Chinese medicine raw materials that can fully sterilize the Chinese medicine raw materials. Summary of the invention

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A high-temperature sterilization device for Chinese medicine raw materials comprises a casing, a base frame is installed inside the casing, the base frame and the casing are movably connected left and right, a placement rack is installed on the base frame, the placement rack and the base frame are movably connected up and down, a driving device connected to the base frame and the placement rack is arranged inside the casing, and a steam inlet nozzle corresponding to the placement rack is arranged on the side wall of the casing.
[0007] During sterilization, the Chinese medicine raw materials are placed on the placement rack in the casing, and then steam enters the casing through the steam inlet nozzle to perform high-temperature sterilization on the Chinese medicine raw materials on the placement rack. At the same time, the driving device will control the bottom frame in the casing to start moving, so that the bottom frame and the placement rack on it will reciprocate left and right in the horizontal direction, thereby sifting the Chinese medicine raw materials on the placement rack left and right, and the driving device will also control the placement rack to reciprocate up and down relative to the bottom frame in the vertical direction, thereby sifting the Chinese medicine raw materials on the placement rack up and down, so as to fully turn over the Chinese medicine raw materials during the sterilization process, thereby ensuring that each portion of Chinese medicine raw material can fully and comprehensively contact with the high-temperature steam, thereby greatly improving the sterilization effect.
[0008] Preferably, the placement rack is provided with a plurality of placement mesh plates, a guide plug-in block is fixed on the side wall of the placement mesh plate, a guide slot matching the guide plug-in block is provided on the placement rack, the placement mesh plate is installed on the placement rack and movably connected with the placement mesh plate through the cooperation of the guide slot and the guide plug-in block, a mesh plate opening matching the placement mesh plate is provided on the side wall of the housing, a sealing cover plate is installed at the mesh plate opening, the sealing cover plate and the mesh plate opening are movably connected, a blocking net matching the placement mesh plate is fixed on the placement rack, and the placement mesh plate is located on the inner side of the blocking net.

[0028] like Figure 1 and Figure 4 As shown, a horizontal slide groove 24 is provided on the side wall of the casing 1, and a horizontal slider 25 matching the horizontal slide groove 24 is fixed on the base frame 2. The base frame 2 is installed on the side wall of the casing 1 through the cooperation of the horizontal slider 25 and the horizontal slide groove 24 and is movably connected to the left and right sides.

[0029] like Figure 2 and Figure 6 As shown, a cam 27 is sleeved on the rotating shaft 19, and the cam 27 and the rotating shaft 19 are fixedly connected. A horizontal plate 28 matching the cam 27 is fixed on the placement frame 3, and the horizontal plate 28 is placed above the cam 27, and the bottom surface of the horizontal plate 28 is in contact with the outer wall of the cam 27.
[0030] like Figure 2 and Figure 6 As shown, a plurality of vertical rods 29 are fixed on the base frame 2, and a vertical rod slide groove 30 matching the vertical rod 29 is provided at the bottom of the placement rack 3.

[0031] Before sterilization, the operator pulls out the topmost placement mesh plate 5 from the placement rack 3 through the mesh plate opening 8, places all the Chinese medicine raw materials on the topmost placement mesh plate 5, and then pushes the placement mesh plate 5 with the Chinese medicine raw materials into the placement rack 3.

At this time, the positioning pin 13 in the positioning pin slide slot 18 can be inserted into the limiting slot 14, so as to fix the placement mesh plate 5 on the placement rack 3.
[0032] During sterilization, high-temperature steam enters the casing 1 through the steam inlet nozzle 4 and impacts the blades 16 on the outside of the drum 15. The thrust of the high-temperature steam drives the drum 15 and the steam vent 17 thereon to rotate, so that the high-temperature steam can be evenly sprayed onto the Chinese medicinal materials on the placement rack 3 through the steam vent 17. At the same time, the driving device will control the base frame 2 in the casing 1 to start moving, so that the base frame 2 and the placement rack 3 thereon will reciprocate left and right in the horizontal direction, thereby sifting the Chinese medicinal materials on the placement rack 3 left and right, and the driving device will also control the placement rack 3 to reciprocate up and down in the vertical direction relative to the base frame 2, thereby sifting the Chinese medicinal materials on the placement rack 3 up and down, so as to fully turn over the Chinese medicinal materials during the sterilization process, and well ensure that each portion of Chinese medicinal materials can fully and comprehensively contact with the high-temperature steam. In addition, when the driving device controls the movement of the base frame 2 and the placement rack 3 to turn over the Chinese medicinal materials on the placement mesh plate 5, the Chinese medicinal materials smaller than the mesh aperture will automatically pass through the mesh holes on the placement mesh plate 5 and fall onto the next layer of the placement mesh plate 5, so that the Chinese medicinal materials can be automatically screened while being sterilized at high temperature.
[0033] Working principle of the driving device: Since the rotating drum 15 and the rotating shaft 19 are fixedly connected by the connecting rod 20, the rotating shaft 15 will also rotate synchronously when the rotating drum 15 rotates. When the rotating rod 21 on the rotating shaft 15 rotates to the position of the upper support block 22, it will push the entire base frame 2 and the placement rack 3 thereon to move toward the left side. When the rotating rod 21 on the rotating shaft 19 rotates to the position of the lower support block 23, it will push the entire base frame 2 and the placement rack 3 thereon to move toward the right side, thereby realizing the left and right screening of the Chinese medicine raw materials on the placement rack 3. When the raised part of the cam 27 on the rotating shaft 19 rotates to the position of the horizontal plate 28, it will push the horizontal plate 28 upward, thereby pushing the placement rack 3 on the base frame 2 to move upward; when the raised part of the cam 27 on the rotating shaft 19 rotates past the horizontal plate 28, the placement rack 3 on the base frame 2 will move downward under the action of gravity, thereby realizing the up and down screening of the Chinese medicine raw materials on the placement rack 3.
[0034] After sterilization, the positioning pin 13 only needs to be pulled out from the limiting slot 14, and the placement screen 5 will automatically pop out under the elastic force of the ejection spring 11, and then the sterilized Chinese medicine raw materials can be removed from the placement screen 5.
