Description

Technical Field

[0001] The invention relates to the technical field of polygonatum polysaccharide extraction equipment, in particular to a polygonatum polysaccharide separation and extraction device and a preparation method. Background Art

[0002] Polygonatum, the name of traditional Chinese medicine, is the dried rhizome of Yunnan Polygonatum, Polygonatum sibiricum or Polygonatum multiflorum of the Liliaceae family. According to different shapes, it is commonly known as "big Polygonatum", "chicken-head Polygonatum", "ginger-shaped Polygonatum". Polygonatum needs to extract the polysaccharides inside during the processing, so it is necessary to use extraction equipment, which mainly involves slicing or crushing the Polygonatum and putting it into the lifting bucket to allow the Polygonatum to fully contact with the liquid, and then remove the impurities.

[0003] During the use of traditional Polygonatum sibiricum polysaccharide extraction barrels, Polygonatum sibiricum and liquid are mixed together. After the extraction is completed, the liquid mixed with Polygonatum sibiricum residue is not convenient to be discharged from the extraction barrel. The pipe is easily blocked during the discharge process, and it is required to be filtered afterwards, which affects the extraction efficiency of Polygonatum sibiricum polysaccharide. At the same time, it is easier to operate Polygonatum sibiricum after cutting it. The smaller the particle size of the cut, the higher the extraction efficiency of Polygonatum sibiricum polysaccharide.

[0004] This case was created to solve the above problems. Summary of the Invention

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0032] like Figure 1-6 As shown: A device for separating and extracting polygonatum polysaccharide and a preparation method thereof, comprising an extraction box 1, a support frame 2, a fixed plate 4 fixed on the support frame 2, a hole in the middle of the fixed plate 4, a cutting structure in the hole, a loading outer cylinder 3 being threadedly connected to the bottom surface of the fixed plate 4, a limiting plate 10 being provided in the extraction box 1, a hole being opened in the middle of the limiting plate 10, a rolling assembly being provided below the limiting plate 10, a reaction cylinder 12 being threadedly connected to the bottom surface of the limiting plate 10, the rolling assembly being located in the reaction cylinder 12 as a whole, the loading inner cylinder being inserted into the loading outer cylinder 3 Inside, fix the loading outer cylinder 3 through a threaded connection, then place the polygonatum to be cut on the cutting blade 6, press down while turning the handle back and forth, driving the support plate 22 to rotate back and forth continuously, thereby controlling the limiting rod 23 to move from one end to the other end in the limiting groove 24 through the limiting groove 24, thereby driving the cutting blade 6 to move continuously inward and outward, thereby realizing the cutting of the polygonatum, and the cut polygonatum falls into the loading inner cylinder 7. When the cutting is completed, remove the loading inner cylinder 7 and put it into the reaction cylinder 12.

[0033] After the loading inner cylinder 7 is placed in the reaction cylinder 12, since the polygonatum inside it has only been preliminarily processed and cut, the telescopic rod 11 is driven up and down by the driving motor 8, thereby driving the vertical plate 14 and the first rolling roller 13 to move up and down, thereby controlling the distance between the first rolling roller 13 and the second rolling roller 21. The worm 15 is controlled to rotate as a whole by an electronic control connection. When the worm 15 rotates, the turbine 19 thereon rotates accordingly, and the first rotating disk 18 and the second rotating disk 20 are driven to rotate through the worm transmission, thereby driving the first rolling roller 13 and the second rolling roller 21 to rotate. The two rotate in opposite directions to each other, thereby rolling the polygonatum between the two, thereby better crushing them and achieving subsequent sufficient reaction. The entire rolling structure is located in the reaction cylinder 12, and its size is also smaller than that of the loading inner cylinder 7. Therefore, part of the polygonatum is in the reaction cylinder and is rolled and ground by the second rolling roller 21 and the bottom of the reaction cylinder, thereby further grinding the polygonatum and achieving sufficient grinding of the polygonatum in the loading inner cylinder 7.

[0034] The cutting structure includes a cutting blade 6, a support plate 22, a limiting rod 23, and a limiting groove 24. The support plate 22 is located in the fixed plate 4. A plurality of limiting grooves 24 are provided on the support plate 22. A plurality of limiting rods 23 are respectively located in a limiting groove 24. The movement of the limiting rod 23 drives the displacement of the cutting blade 6.

[0036] The rolling assembly includes a first rolling roller 13, a vertical plate 14, a worm 15, a first rotating disk 18, a second rotating disk 20, and a second rolling roller 21. A drive motor 8 is provided on the inner side wall of the extraction box 1. The output end of the drive motor 8 is connected to the connecting rod 9. The end of the connecting rod 9 is connected to a telescopic rod 11. The end of the telescopic rod 11 is connected to the vertical plate 14. The drive motor 8 drives the telescopic rod 11 to move up and down, thereby controlling the distance between the first rolling roller 13 and the second rolling roller 21.

[0037] The end of the first laminating roller 13 passes through the vertical plate 14 and is connected to the first rotating disk 18. The first laminating roller 13 is rotatably connected to the vertical plate 14. The end of the first laminating roller 13 is fixedly connected to the first rotating disk 18. A plurality of ridges 17 are provided on the first rotating disk 18. As the worm 15 rotates, the turbine 19 is driven to reciprocate, so that the ridges 17 rotate as the turbine 19 moves, driving the first rotating disk 18 to rotate. The diameter of the ridges 17 is smaller than the distance between the two turbines 19.

[0038] A worm 15 is provided below the first rotating disk 18, and a turbine 19 is provided on the worm 15. The turbine 19 engages with the ridges 17 on the first rotating disk 18. Both ends of the worm 15 are rotatably connected to the support columns 16, and the tops of the two support columns 16 are fixedly connected to the limit plates 10, thereby achieving fixed limiting.

[0039] A second rolling roller 21 is provided below the worm 15, and a second rotating disk 20 is provided at the end of the second rolling roller 21. A plurality of ridges 17 are circumferentially provided on the inner side surface of the second rotating disk 20. The second rotating disk 20 is arranged opposite to the first rotating disk 18. The ridges 17 on the second rotating disk 20 are engaged with the turbine 19. A fixed vertical plate is provided downwardly on the limiting plate 10, and the rear end of the second rolling roller 21 is rotatably connected to the fixed vertical plate, so that the position of the second rolling roller 21 is fixed.

[0040] A loading inner cylinder 7 is provided inside the loading outer cylinder 3. A plurality of holes are provided on the wall of the loading inner cylinder 7. When the Polygonatum odoratum is crushed, the residue remains in the loading inner cylinder 7 and will not be taken out, while the liquid after the reaction flows into the reaction cylinder along the holes, realizing precise separation. The size of the loading inner cylinder 7 is smaller than that of the reaction cylinder 12.

[0041] The bottom of the extraction box 1 is provided with a sedimentation cylinder 25, a centrifugal chamber 26 is provided in the sedimentation cylinder 25, and a plurality of reaction rollers 29 are circumferentially connected to the lower end of the centrifugal chamber 26.

An opening and a closing port are provided at the connection between the reaction cylinder 12 and the connecting pipe 27. When the pipe is not connected, the opening can be directly closed, and the other end extends into the sedimentation cylinder 25. A collection pipe is connected to the side wall of the sedimentation cylinder 25. When the liquid in the reaction cylinder 12 undergoes subsequent reaction along the connecting pipe, the liquid is collected. 27 flows into the sedimentation tube 25. At this time, the inflowing liquid may be mixed with small granular fixed sediments that exist after grinding. These particles also enter the sedimentation tube 25 along the connecting pipe 27. At this time, the centrifugal chamber 26 in the sedimentation tube 25 starts to work under the electrical control connection. The centrifugal chamber 26 and the reaction roller 29 rotate, and the particles in the inflowing liquid are thrown out and adsorbed on the side wall of the sedimentation tube 25, ensuring that there are no small particles in the liquid after the reaction, and obtaining high-purity liquid. At this time, this part of the liquid flows out along the collection pipe 28.
