Abstract
Description
Technical Field
[0001] This application relates to the field of traditional Chinese medicine material processing, and specifically to an apparatus for freeze-drying traditional Chinese medicine materials.
Background Art
[0002] In the manufacturing and processing process of traditional Chinese medicine materials such as Angelica dahurica, the traditional sulfur fumigation drying method can better preserve the active ingredients of traditional Chinese medicine materials. However, the sulfur dioxide in traditional Chinese medicine materials exceeds the standard, which has a serious impact on the quality of traditional Chinese medicine materials, and the storage time is short. On the contrary, the vacuum freeze-processing technology of traditional Chinese medicine materials can maximize the preservation of the activities of various medicinal and nutritional components such as ferulic acid, polysaccharides, and volatile oils in traditional Chinese medicine materials, and can well maintain the appearance quality, color, and odor of the medicinal materials, with thorough dehydration, long storage time, and advantages that are incomparable to other drying technologies.
[0003] On the other hand, when freeze-processing traditional Chinese medicine materials such as Angelica dahurica, after slicing traditional Chinese medicine materials such as Angelica dahurica and placing them in a tray, it is necessary to put them into freeze-drying equipment for freeze-drying treatment. Since it is difficult for such freeze-drying equipment to simultaneously freeze-dry both sides of traditional Chinese medicine materials, the processing efficiency is low.
Summary of the Invention
Means for Solving the Problems
[0004] To make up for the above deficiencies, this application provides an apparatus for freeze-drying traditional Chinese medicine materials, aiming to improve the problem of low processing efficiency.
[0005] The embodiments of the present application provide a processing device for freeze-drying traditional Chinese medicine materials, which has a drying box, a tray and a refrigerant transport pipe. The tray is slidably mounted inside the drying box. A hollow plate body is mounted on the upper end surface of the tray at intervals, and a communication pipe is connected between the hollow plate bodies. An upper circular pipe is connected to the bottom end of the communication pipe. The refrigerant transport pipe is mounted inside the drying box, and a lower circular pipe is connected to the refrigerant transport pipe. A pipe joint is provided at the tip of the lower circular pipe, and the upper circular pipe is sheathed on the surface of the pipe joint.
[0006] In the above implementation process, after slicing traditional Chinese medicine materials such as angelica dahurica, place them between two adjacent hollow plate bodies on the surface of the tray, transport the refrigerant medium into the refrigerant transport pipe. The refrigerant medium enters the communication pipe through the lower circular pipe, the pipe joint and the upper circular pipe, and then is transported into the hollow plate body, and the refrigerant medium can freeze and dry the sheet-shaped traditional Chinese medicine materials located between the two hollow plate bodies. Also, because the sheet-shaped traditional Chinese medicine is located between the two hollow plate bodies, the refrigerant medium can freeze the sheet-shaped traditional Chinese medicine materials from both sides, enhancing the freezing effect, significantly increasing the drying speed, effectively reducing the processing time, and improving the processing efficiency.
[0007] In a specific embodiment, one side of the drying box is provided with a embossed pattern, and a box door is mounted on the embossed pattern side of the drying box.
[0008] In the above implementation process, by providing the box door, the embossed pattern side of the drying box can be easily closed. After closing the drying box, the inside of the drying box can be made into a vacuum state using equipment such as a vacuum generator, which is more advantageous for freeze-drying traditional Chinese medicine materials.
[0009] In a specific embodiment, a protrusion is provided around the tray, a protrusion block is mounted on the inner wall of the drying box, and the protrusion around the tray is arranged on the surface of the protrusion block.
[0010] In the above implementation process, by providing a protrusion block for supporting the protrusions around the tray, the tray can be installed in the drying box.
[0011] In a specific embodiment, the hollow plate body is inclined on the upper end surface of the tray, and an arrangement groove is formed between the hollow plate bodies.
[0012] In the above implementation process, providing the hollow plate body inclined on the surface of the tray can effectively reduce the height of the hollow plate body and the entire tray compared to providing it vertically, and it can be conveniently used even in a narrow workspace.
[0013] In a specific embodiment, the communication pipe is an angle steel pipe, and the end of the communication pipe is provided in a closed state.
[0014] In the above implementation process, since the end is provided in a closed state, it is possible to prevent the refrigerant medium from flowing out from the end of the communication pipe.
[0015] In a specific embodiment, the communication pipe is located at the bottom end of the hollow plate body, and the upper end surface of the communication pipe and the lower end surface of the tray are fixedly connected.
[0016] In the above implementation process, the tray can be supported by the communication pipe, and the compression capacity of the tray can be enhanced.
[0017] In a specific embodiment, the upper circular pipe, the lower circular pipe, and the pipe joint are provided coaxially.
[0018] In a specific embodiment, it further includes a refrigeration system connected to the refrigerant transport pipe.
[0019] In the above implementation process, by providing a refrigeration system, the refrigerant medium in the refrigerant transport pipe is refrigerated.
[0020] In a specific embodiment, the refrigeration system includes a circulation pump and a refrigerator. Two refrigerant transport pipes are provided, and the two refrigerant transport pipes are respectively connected to the output end and the input end of the circulation pump. The refrigerator is connected to one of the refrigerant transport pipes.
[0021] In the above execution process, by providing a circulation pump used for the circulating transportation of the refrigerant medium, it is advantageous for the use of the refrigerant medium.
[0022] In a specific embodiment, two communication pipes are provided on the lower end surface of the tray, and the two communication pipes are respectively communicated with the corresponding refrigerant transport pipes. The refrigerator is a semiconductor refrigerator.
[0023] In the above execution process, by providing two communication pipes, the circulating transportation of the refrigerant medium is facilitated.
[0024] In a specific embodiment, the pipe joint is a cylindrical joint with a large diameter in the middle and small diameters at both ends. The pipe joint is rotatably connected to the lower circular pipe. An annular protrusion is provided at the lower end of the pipe joint, and the annular protrusion is rotatably engaged inside the lower circular pipe. A first blocking plate is fixedly attached inside the lower circular pipe, and a second blocking plate is attached to the bottom end of the pipe joint. Both the first blocking plate and the second blocking plate are semi-circular plates, and the upper end surface of the first blocking plate and the lower end surface of the second blocking plate are adhesively bonded to be sealed.
[0025] In the above execution process, by rotating the pipe joint to rotate the second blocking plate and further shift the second blocking plate and the first blocking plate, the semi-circular first blocking plate and second blocking plate are respectively located on both sides inside the lower circular pipe. The first blocking plate and the second blocking plate block the lower circular pipe, and after the first blocking plate and the second blocking plate block the flow of the refrigerant medium, by removing the upper circular pipe from the surface of the pipe joint, the leakage of the refrigerant medium can be effectively avoided.
[0026] In a specific embodiment, a position limiting block is attached to the body of the upper circular pipe, and an arc plate is covered on the surface of the position limiting block. A clearance fit is provided between the outer wall of the position limiting block and the inner wall of the arc plate. The bottom end of the arc plate is fixedly connected to the central part of the pipe joint, and a position limiting plate corresponding to the position limiting block is attached to the tip of the arc plate.
[0027] In the above execution process, after covering the upper circular pipe on the surface of the pipe joint, rotate the pipe joint to move the position limiting plate by the arc plate on the surface of the pipe joint, cover the arc plate on the surface of the position limiting block on the outer wall of the upper circular pipe. When the position limiting plate moves above the position limiting block and the second blocking plate at the bottom end of the pipe joint moves above the first blocking plate, the second blocking plate and the first blocking plate overlap, and the refrigerant medium transported from the refrigerant transport pipe can be transported into the pipe joint through the lower circular pipe and further into the upper circular pipe. Also, since the position limiting plate restricts the movement of the position limiting block, it is possible to avoid the possibility that the upper circular pipe falls off the surface of the pipe joint due to the impact of the refrigerant medium.
[0028] In a specific embodiment, the upper end surface of the position limiting block and the lower end surface of the position limiting plate are bonded together.
[0029] In a specific embodiment, a slide cover plate is slidably provided inside the communication pipe, and the slide cover plate is located directly above the upper circular pipe. A spring is attached between the upper end surface of the slide cover plate and the inner tip of the communication pipe. The lower end surface of the slide cover plate is bonded to the tip of the upper circular pipe in a sealed manner, and a push block corresponding to the slide cover plate is provided at the tip of the pipe joint.
[0030] In the above execution process, after covering the upper circular tube on the surface of the pipe joint, the push block at the tip of the pipe joint pushes and moves the slide cover plate, separates the slide cover plate from the tip of the upper circular tube, and the slide cover plate pushes out the spring, enabling the refrigerant medium to enter the upper circular tube through the pipe joint. On the other hand, when removing the upper circular tube from the surface of the pipe joint, with the support of the spring, the slide cover moves downward to the tip of the upper circular tube, and by closing the tip of the upper circular tube, the discharge of the refrigerant medium in the communication pipe can be avoided, and the possibility of refrigerant medium leakage can be reduced.
[0031] In a specific embodiment, a guide block is attached to the lower end surface of the slide cover plate, a groove matching the guide block is opened on the inner wall of the upper circular tube, the lower end of the guide block is slidably inserted into the groove on the inner wall of the guide block, and the central part of the pipe joint is bonded to the bottom end of the upper circular tube so as to be sealed.
[0032] In the above execution process, the upper circular tube can further limit the movement range of the slide cover plate by restricting the movement range of the guide block, and the movement of the slide cover plate can be made more stable.
Advantages of the Invention
[0033] The beneficial effects are as follows. This application provides a processing device for freeze-drying traditional Chinese medicinal materials. A hollow plate body is provided at intervals on the surface of the tray, and the traditional Chinese medicinal materials to be freeze-dried are placed between two adjacent hollow plate bodies. The refrigerant in the hollow plate body is used to perform freezing from both sides of the hollow plate material, greatly enhancing the freezing effect, effectively reducing the processing time, and improving the processing efficiency.
[0034] When using a removable pipeline to convey the refrigerant medium, when the pipeline is removed, it becomes difficult to close the conveying pipeline, and the phenomenon of refrigerant medium leakage is likely to occur, which is disadvantageous for use.
[0035] In the present application, when the pipe joint is rotated to rotate the second shut-off plate and further shift the second shut-off plate and the first shut-off plate, the first shut-off plate and the second shut-off plate forming a semi-circular shape are respectively located on both inner sides of the lower circular pipe. The first shut-off plate and the second shut-off plate block the lower circular pipe, and after the first shut-off plate and the second shut-off plate block the flow of the refrigerant medium, by removing the upper circular pipe from the surface of the pipe joint, the leakage of the refrigerant medium can be effectively avoided.
[0036] After covering the upper circular pipe on the surface of the pipe joint, the pipe joint is rotated, and the positioning plate is moved by the arc plate on the surface of the pipe joint. The arc plate is covered on the surface of the positioning block on the outer wall of the upper circular pipe. As the positioning plate moves above the positioning block and the second shut-off plate at the bottom end of the pipe joint moves above the first shut-off plate, the second shut-off plate and the first shut-off plate overlap. The refrigerant medium transported from the refrigerant transport pipe can be transported into the pipe joint through the lower circular pipe and further transported into the upper circular pipe. Also, since the positioning plate restricts the movement of the positioning block, the possibility of the upper circular pipe falling off from the surface of the pipe joint due to the impact of the refrigerant medium can be avoided.
[0037] When using the tray as a carrier and providing a refrigeration structure on its surface, traditional Chinese medicinal materials can be well refrigerated. However, when the refrigeration structure and the refrigerant transport pipeline are separated, it becomes difficult to close the port of the refrigeration structure, and a phenomenon of refrigerant medium leakage occurs, which is disadvantageous for use.
[0038] In the present application, after covering the upper circular pipe on the surface of the pipe joint, the push block at the tip of the pipe joint pushes and moves the slide cover plate, separating the slide cover plate from the tip of the upper circular pipe. Moreover, the slide cover plate pushes out the spring, and the refrigerant medium can enter the upper circular pipe through the pipe joint. On the other hand, by removing the upper circular pipe from the surface of the pipe joint, the slide cover moves downward to the tip of the upper circular pipe with the support of the spring, and by closing the tip of the upper circular pipe, the discharge of the refrigeration medium in the communication pipe can be avoided, and the possibility of refrigerant medium leakage can be reduced.

Embodiments for Carrying Out the Invention
[0040] Hereinafter, the technical means in the embodiments of the present application will be described based on the drawings in the embodiments of the present application.
[0041] Referring to FIGS. 1-8, the embodiments of the present application provide a processing device for freeze-drying traditional Chinese medicinal materials, which includes a drying box 100, a tray 200, and a refrigerant transport pipe 300. Here, both the tray 200 and the refrigerant transport pipe 300 are provided in the drying box 100.
[0042] The tray 200 is slidably mounted inside the drying box 100. A hollow plate body 210 is mounted on the upper end surface of the tray 200 at intervals, and a communication pipe 220 is communicated between the hollow plate bodies 210. An upper circular pipe 230 is communicated with the bottom end of the communication pipe 220. The refrigerant transport pipe 300 is mounted inside the drying box 100, and a lower circular pipe 310 is communicated with the refrigerant transport pipe 300. A pipe joint 320 is provided at the tip of the lower circular pipe 310, and the upper circular pipe 230 is sleeved on the surface of the pipe joint 320.
[0043] In the above execution process, after slicing traditional Chinese medicinal materials such as Chinese angelica, place them between two adjacent hollow plate bodies 210 on the surface of the tray 200, transport the refrigerant medium into the refrigerant transport pipe 300. The refrigerant medium enters the communication pipe 220 through the lower circular pipe 310, the pipe joint 320 and the upper circular pipe 230, and then is transported into the hollow plate body 210. The refrigerant medium can freeze and dry the sheet-shaped traditional Chinese medicinal materials located between the two hollow plate bodies 210. Also, since the sheet-shaped traditional Chinese medicine is located between the two hollow plate bodies 210, the refrigerant medium can freeze the sheet-shaped traditional Chinese medicinal materials from both sides, enhancing the freezing effect, significantly increasing the drying speed, effectively reducing the processing time, and improving the processing efficiency.
[0044] In a specific embodiment, one side of the drying box 100 is provided with a watermark engraving, and a box door is mounted on the watermark engraving side of the drying box 100.
[0045] In the above execution process, by providing the box door, the watermark engraving side of the drying box 100 can be easily closed. After closing the drying box 100, the inside of the drying box 100 can be made into a vacuum state using equipment such as a vacuum generator, which is more advantageous for the freeze-drying of traditional Chinese medicinal materials.
[0046] In a specific embodiment, a protrusion is provided around the tray 200, a protrusion block 110 is mounted on the inner wall of the drying box 100, and the protrusion around the tray 200 is arranged on the surface of the protrusion block 110.
[0047] In the above execution process, by providing the protruding block 110 for supporting the protrusions around the tray 200, the tray 200 can be installed in the drying box 100.
[0048] In a specific embodiment, the hollow plate body 210 is inclined on the upper end surface of the tray 200, and a placement groove is formed between the hollow plate bodies 210.
[0049] In the above execution process, providing the hollow plate body 210 inclined on the surface of the tray 200 can effectively reduce the height of the hollow plate body 210 and the entire tray 200 compared to providing it vertically, and it can be conveniently used even in a narrow workspace.
[0050] In a specific embodiment, the communication pipe 220 is an angle steel pipe, and the ends of the communication pipe 220 are provided in a closed state.
[0051] In the above execution process, since the ends are provided in a closed state, it is possible to prevent the refrigerant medium from flowing out from the ends of the communication pipe 220.
[0052] In a specific embodiment, the communication pipe 220 is located at the bottom end of the hollow plate body 210, and the upper end surface of the communication pipe 220 and the lower end surface of the tray 200 are fixedly connected.
[0053] In the above execution process, the communication pipe 220 can support the tray 200 and enhance the compression capacity of the tray 200.
[0054] In a specific embodiment, the upper circular pipe 230, the lower circular pipe 310, and the pipe joint 320 are provided coaxially.
[0055] In a specific embodiment, it further includes a refrigeration system 400 connected to the refrigerant transport pipe 300.
[0056] In the above execution process, by providing the refrigeration system 400, the refrigerant medium in the refrigerant transport pipe 300 is refrigerated.
[0057] In a specific embodiment, the refrigeration system 400 includes a circulation pump 410 and a refrigerator 420. Two refrigerant transport pipes 300 are provided, and the two refrigerant transport pipes 300 are respectively connected to the output end and the input end of the circulation pump 410. The refrigerator 420 is connected to one of the refrigerant transport pipes 300.
[0058] In the above execution process, by providing the circulation pump 410 used for the circulating transport of the refrigerant medium, it is advantageous for the use of the refrigerant medium.
[0059] In a specific embodiment, two communication pipes 220 are provided on the lower end surface of the tray 200, and the two communication pipes 220 are respectively communicated with the corresponding refrigerant transport pipes 300. The refrigerator 420 is a semiconductor refrigerator.
[0060] In the above execution process, by providing the two communication pipes 220, the circulating transport of the refrigerant medium is facilitated.
[0061] When using a removable pipeline to transport the refrigerant medium, when the pipeline is removed, it becomes difficult to close the transport pipeline, and the phenomenon of refrigerant medium leakage is likely to occur, which is disadvantageous for use.
[0062] In a specific embodiment, the pipe joint 320 is a cylindrical joint with a large diameter in the middle and small diameters at both ends. The pipe joint 320 is rotatably connected to the lower circular pipe 310. An annular protrusion 321 is provided at the lower end of the pipe joint 320, and the annular protrusion 321 is rotatably engaged inside the lower circular pipe 310. A first blocking plate 311 is fixedly attached inside the lower circular pipe 310. A second blocking plate 322 is attached to the bottom end of the pipe joint 320. Both the first blocking plate 311 and the second blocking plate 322 are semi-circular plate materials, and the upper end surface of the first blocking plate 311 and the lower end surface of the second blocking plate 322 are bonded together to be sealed.
[0063] In the above execution process, by rotating the pipe joint 320, the second shut-off plate 322 is rotated, and further when the second shut-off plate 322 and the first shut-off plate 311 are displaced, the first shut-off plate 311 and the second shut-off plate 322 forming a semi-circular shape are respectively located on both inner sides of the lower circular pipe 310. The first shut-off plate 311 and the second shut-off plate 322 block the lower circular pipe 310, and after the first shut-off plate 311 and the second shut-off plate 322 block the flow of the refrigerant medium, by removing the upper circular pipe 230 from the surface of the pipe joint 320, the leakage of the refrigerant medium can be effectively avoided.
[0064] As can be understood, seal rings can be provided at both the connection location between the pipe joint 320 and the lower circular pipe 310 and the connection location between the pipe joint 320 and the upper circular pipe 230. The seal ring is fixed only to the pipe joint 320, and the lower circular pipe 310 and the upper circular pipe 230 are only in close contact with the inner wall of the seal ring. On the premise that the rotation of the pipe joint 320 is not affected, the sealing performance between the lower circular pipe 310, the upper circular pipe 230, and the pipe joint 320 can be enhanced.
[0065] In a specific embodiment, a position limiting block 231 is attached to the body of the upper circular pipe 230, and an arc plate 330 is covered on the surface of the position limiting block 231. A clearance fit is provided between the outer wall of the position limiting block 231 and the inner wall of the arc plate 330. The bottom end of the arc plate 330 and the central part of the pipe joint 320 are fixedly connected, and a position limiting plate 340 corresponding to the position limiting block 231 is attached to the tip of the arc plate 330.
[0066] In the above execution process, after covering the upper circular pipe 230 on the surface of the pipe joint 320, the pipe joint 320 is rotated, and the position limiting plate 340 is moved by the arc plate 330 on the surface of the pipe joint 320. The arc plate 330 is covered on the surface of the position limiting block 231 on the outer wall of the upper circular pipe 230. As the position limiting plate 340 moves above the position limiting block 231 and the second shut-off plate 322 at the bottom end of the pipe joint 320 moves above the first shut-off plate 311, the second shut-off plate 322 and the first shut-off plate 311 overlap. The refrigerant medium transported from the refrigerant transport pipe 300 can be transported into the pipe joint 320 through the lower circular pipe 310 and further into the upper circular pipe 230. Also, since the position limiting plate 340 limits the movement of the position limiting block 231, it is possible to avoid the possibility that the upper circular pipe 230 falls off the surface of the pipe joint 320 due to the impact of the refrigerant medium.
[0067] As can be understood, the first shut-off plate 311 and the position limiting block 231 are located on the same side inside the lower circular pipe 310. When the second shut-off plate 322 and the position limiting plate 340 are located on the same side of the pipe joint 320, as the position limiting plate 340 moves above the position limiting block 231, the second shut-off plate 322 also moves right above the first shut-off plate 311. When the lower circular pipe 310 and the pipe joint 320 communicate, the position limiting plate 340 locks to the position limiting block 231, and the upper circular pipe 230 will not fall off the surface of the pipe joint 320 during the conveyance of the refrigerant medium.
[0068] Preferably, anti-slip rubber pads are provided on both the lower end surface of the position limiting plate 340 and the upper end surface of the position limiting block 231, so as to enhance the anti-slip effect between the position limiting plate 340 and the position limiting block 231.
[0069] In a specific embodiment, the upper end surface of the position limiting block 231 and the lower end surface of the position limiting plate 340 are adhered to each other.
[0070] When using a tray as a carrier and providing a refrigeration structure on its surface, Chinese medicinal materials can be well refrigerated. However, when the refrigeration structure and the refrigerant transport pipeline are separated, it becomes difficult to close the ports of the refrigeration structure, and a phenomenon of refrigerant medium leakage occurs, which is disadvantageous for use.
[0071] In a specific embodiment, a slide cover plate 500 is slidably provided inside the communication pipe 220. The slide cover plate 500 is located directly above the upper circular pipe 230. A spring is attached between the upper end surface of the slide cover plate 500 and the inner tip of the communication pipe 220. The lower end surface of the slide cover plate 500 is adhesively attached to the tip of the upper circular pipe 230 in a sealed manner. A push block 350 corresponding to the slide cover plate 500 is provided at the tip of the pipe joint 320.
[0072] In the above execution process, after covering the upper circular pipe 230 on the surface of the pipe joint 320, the push block 350 at the tip of the pipe joint 320 pushes and moves the slide cover plate 500, separating the slide cover plate 500 from the tip of the upper circular pipe 230. The slide cover plate 500 pushes out the spring, and the refrigerant medium can enter the upper circular pipe 230 through the pipe joint 320. On the other hand, when the upper circular pipe 230 is removed from the surface of the pipe joint 320, the slide cover 500 moves downward to the tip of the upper circular pipe 230 under the support of the spring, closing the tip of the upper circular pipe 230, thereby avoiding the discharge of the refrigeration medium in the communication pipe 220 and reducing the possibility of refrigerant medium leakage.
[0073] In a specific embodiment, a guide block 510 is attached to the lower end surface of the slide cover plate 500. A groove that mates with the guide block 510 is opened on the inner wall of the upper circular pipe 230. The lower end of the guide block 510 is slidably inserted into the groove on the inner wall of the guide block 510. The central part of the pipe joint 320 is adhesively attached to the bottom end of the upper circular pipe 230 in a sealed manner.
[0074] In the above execution process, the upper circular pipe 230 can further limit the movement range of the slide cover plate 500 by limiting the movement range of the guide block 510, and can make the movement of the slide cover plate 500 more stable.
[0075] Specifically, when using the processing device for freeze-drying traditional Chinese medicinal materials, after slicing traditional Chinese medicinal materials such as Angelica dahurica, place them between two adjacent hollow plate bodies 210 on the surface of the tray 200, transport the refrigerant medium into the refrigerant transport pipe 300, and the refrigerant medium enters the communication pipe 220 through the lower circular pipe 310, the pipe joint 320 and the upper circular pipe 230, and then is transported into the hollow plate body 210. The refrigerant medium can freeze and dry the sheet-shaped traditional Chinese medicinal materials located between the two hollow plate bodies 210. Also, since the sheet-shaped traditional Chinese medicine is located between the two hollow plate bodies 210, the refrigerant medium can freeze the sheet-shaped traditional Chinese medicinal materials from both sides, enhancing the freezing effect, significantly increasing the drying speed, effectively reducing the processing time, and improving the processing efficiency.
[0076] In addition, the upper circular pipe 230 is covered on the surface of the pipe joint 320, making it easy to detach. The tray 200 can be easily removed from the surface of the pipe joint 320, and the removed tray 200 can be inverted, and the freeze-dried sheet-shaped traditional Chinese medicinal materials on the surface of the tray 200 can be easily poured out.
