Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of extraction equipment, in particular to a synchronous extraction device for polysaccharide and triterpenes in Poria cocos. BACKGROUND

[0002] Polysaccharide and triterpenes in Poria cocos are the core substances for Poria cocos to play a pharmacological effect. Polysaccharide in Poria cocos is of great concern due to its excellent immune enhancement and regulation function, and can effectively activate immune cells and is often used for adjuvant therapy of tumors and defense enhancement of the body. Triterpenes in Poria cocos show significant anti-tumor, anti-inflammatory and liver protection activities, and can directly inhibit the growth of various cancer cells and reduce inflammation and liver damage. The two often act synergistically and jointly constitute the modern scientific basis for the traditional functions of Poria cocos, such as water-dampness elimination, spleen strengthening and spirit calming.

[0003] A method for simultaneously extracting polysaccharide and triterpenes in Poria cocos is disclosed in Chinese patent application No. CN117736350A, which belongs to the technical field of biological extraction. The invention uses a specific first solvent and a second solvent together with water as a solvent, which increases the solubility of triterpenes in the upper phase, allowing them to be enriched in the upper phase. At the same time, the dissolution of polysaccharide by alkali salt allows it to be enriched in the lower phase, forming a double water phase during the extraction of Poria cocos, which realizes the simultaneous extraction and separation of triterpenes in the upper phase and polysaccharide in the lower phase. The polysaccharide yield is close to 5%, the extraction rate is 79.9%, the triterpene yield is 0.44% (4.4mg / g), and the extraction rate is 63.7%. Moreover, the method of the invention uses solvents and alkali salts to realize the natural separation of the upper and lower phases, saving time, effort and material, and being simple to operate, mild in reaction and of wide application value.

[0004] The existing method for simultaneously extracting polysaccharide and triterpenes in Poria cocos requires the use of a mixed solvent to dissolve Poria cocos powder. The polysaccharide and triterpenes in Poria cocos powder are dissolved in different liquid phases. To improve the extraction rate of the mixed solvent for polysaccharide and triterpenes in Poria cocos, a stirring device can be used to stir the mixed solvent and Poria cocos powder, allowing the mixed solvent to fully contact the Poria cocos powder and improve the yield of the mixed solvent for polysaccharide and triterpenes in Poria cocos. After stirring, the solution is allowed to stand and separate into an upper layer solution rich in triterpenes and a lower layer solution rich in polysaccharide. However, traditional stirring equipment cannot improve the uniformity of the mixture of Poria cocos powder and mixed solvent, which slows down the dissolution of polysaccharide and triterpenes in Poria cocos powder into the mixed solvent, resulting in low extraction efficiency of Poria cocos powder. Therefore, it is necessary to redesign a device that meets the existing extraction method of effective substances in Poria cocos powder. SUMMARY

[0005] The purpose of the present application is to provide a synchronous extraction device for polysaccharide and triterpenes in Poria cocos, to solve the problem of insufficient uniformity of Poria cocos powder in the mixed solvent in the prior art, which prevents the effective substances in Poria cocos powder from being fully dissolved in the mixed solvent.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for simultaneous extraction of Poria cocos polysaccharides and triterpenes, comprising:

[0007] A housing, on which a rotary drive component is connected;

[0008] A forward / reverse adjustment assembly, disposed on the housing, includes a drive gear connected to the rotary drive component, an upper connecting pipe connected to the housing, and an upper driven gear connected to the upper connecting pipe. A lower connecting pipe is rotatably connected to the upper driven gear, and a lower driven gear is rotatably connected to the lower connecting pipe. A connecting plate is connected to the housing, and a drive shaft is rotatably connected to the connecting plate. One end of the drive shaft is connected to an intermediate gear that meshes with the upper driven gear. The intermediate gear meshes with both the upper and lower driven gears. The other end of the drive shaft is connected to a side gear. A base plate is connected to the inner wall of the housing, and the base plate is provided with:

[0009] An external rotating stirring assembly is connected to the side gear drive and rotates under the action of the side gear;

[0010] The internal rotating stirring assembly is connected to the upper driven gear or the lower driven gear, and includes a stirring shaft inserted into the upper driven gear and the lower driven gear. The upper driven gear and the lower driven gear are both provided with a slot, and a locking post is provided in the slot. The inner wall of the slot away from the stirring shaft is inclined.

[0011] Preferably, the cross-section of the slot is trapezoidal, meaning that one side of the slot is deeper than the other side, and the locking post is configured as follows:

[0012] When the locking pin is located at the deep side of the locking groove, the locking pin rotates between the driven gear and the stirring shaft, and no power is transmitted between the driven gear and the stirring shaft;

[0013] When the locking pin is located on the shallow side of the locking groove, the locking pin is engaged between the driven gear and the stirring shaft, and the driven gear transmits power to the stirring shaft through the locking pin.

[0014] Preferably, the diameter of the locking pin is greater than the depth of either side of the locking slot.

[0015] Preferably, the external rotating stirring assembly includes a rotating ring connected to the base plate, a mounting column connected to the rotating ring, and a gear ring connected to the mounting column. The gear ring meshes with the side gear, and an external rotating plate is connected to the mounting column. The external rotating plate is a counterclockwise spiral plate.

[0016] Preferably, the stirring shaft is rotatably connected to the base plate, and the inner rotating stirring assembly further includes a lower driven gear connected to the upper end of the stirring shaft and an inner rotating plate connected to the stirring shaft. The lower driven gear meshes with the intermediate gear, and the inner rotating plate is a spiral plate that spirals upward counterclockwise.

[0017] Preferably, the outer rotating plate and the inner rotating plate are arranged alternately.

[0018] Preferably, the upper end of the outer shell is connected to a feed pipe, the lower end of the outer shell is connected to a distribution valve, and the distribution valve is connected to a discharge pipe.

[0019] Preferably, the stirring axis of the outer rotating stirring assembly and the inner rotating stirring assembly overlaps with the axis of the outer shell, and the rotating drive component is a motor.

[0020] Compared with the prior art, the present invention provides a device for simultaneous extraction of Poria cocos polysaccharides and triterpenes. By setting a forward and reverse rotation adjustment component, an outer rotating stirring component, and an inner rotating stirring component inside the shell, when the rotating drive rotates forward to drive the forward and reverse rotation adjustment component, the forward and reverse rotation adjustment component drives the outer rotating stirring component to rotate in reverse, and at the same time drives the inner rotating stirring component to rotate forward. At this time, the rotation directions of the inner and outer rotating stirring components are opposite. The two rotating stirring components increase the degree of turbulent mixing between the mixed solvent and Poria cocos powder inside the shell, so that the Poria cocos powder is evenly dispersed in the mixed solvent. This allows different liquid phases in the mixed solvent to fully extract the Poria cocos polysaccharides and triterpenes from the Poria cocos powder, thereby improving the extraction rate of effective substances from the Poria cocos powder.

[0021] After the effective substances of Poria cocos powder are extracted, the rotating drive is reversed to drive the forward and reverse rotation adjustment component to operate. The forward and reverse rotation adjustment component drives the outer rotating stirring component to rotate forward, and at the same time drives the inner rotating stirring component to rotate forward. At this time, the rotation direction of the inner and outer rotating stirring components is the same. The rotating stirring component drives the mixed solvent inside the shell to rotate slowly until the mixed solvent precipitates and separates into layers, so as to obtain a solution rich in Poria cocos polysaccharides, a solution rich in triterpenes, and Poria cocos powder precipitate.

[0035] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] As attached Figure 1 To be continued Figure 10 As shown:

[0037] Example 1:

[0038] This invention provides a device for the simultaneous extraction of Poria cocos polysaccharides and triterpenes, comprising:

[0039] The outer casing 1 is connected to a rotary drive component, which is a motor 5.

[0040] A forward / reverse adjustment assembly, disposed on the housing 1, includes a drive gear 6 connected to the rotary drive component, an upper connecting pipe 7 connected to the housing 1, and an upper driven gear 8 connected to the upper connecting pipe 7. A lower connecting pipe 11 is rotatably connected to the upper driven gear 8, and a lower driven gear 12 is rotatably connected to the lower connecting pipe 11. A connecting plate 9 is connected to the housing 1, and a drive shaft is rotatably connected to the connecting plate 9. One end of the drive shaft is connected to an intermediate gear 10 that meshes with the upper driven gear 8. The intermediate gear 10 meshes with both the upper driven gear 8 and the lower driven gear 12. The other end of the drive shaft is connected to a side gear 13. A base plate 14 is connected to the inner wall of the housing 1, and the base plate 14 is provided with:

[0041] The external rotating stirring assembly is connected to the side gear 13 and rotates under the action of the side gear 13;

[0042] The inner rotating stirring assembly is connected to the upper driven gear 8 or the lower driven gear 12. It includes a stirring shaft 19 inserted into the upper driven gear 8 and the lower driven gear 12. The inner walls of the upper driven gear 8 and the lower driven gear 12 are provided with slots 21. A locking post 22 is provided in the slot 21. The inner wall of the slot 21 away from the stirring shaft 19 is inclined. In order to facilitate the mutual interference between the inner and outer rotating stirring assemblies, the stirring axis of the outer rotating stirring assembly and the inner rotating stirring assembly overlaps with the axis of the outer shell 1.

[0043] As can be seen from the above, by setting a forward / reverse adjustment component, an outer rotating stirring component, and an inner rotating stirring component inside the outer shell 1, when the rotating drive rotates forward to drive the forward / reverse adjustment component to operate, the forward / reverse adjustment component drives the outer rotating stirring component to rotate in reverse, and at the same time drives the inner rotating stirring component to rotate forward. At this time, the rotation directions of the inner and outer rotating stirring components are opposite. The two rotating stirring components increase the degree of turbulent mixing between the mixed solvent and Poria cocos powder inside the outer shell 1, so that the Poria cocos powder is evenly dispersed in the mixed solvent, and the different liquid phases in the mixed solvent fully extract the Poria cocos polysaccharides and triterpenoids in the Poria cocos powder, thereby improving the extraction rate of effective substances from the Poria cocos powder.

[0044] After the effective substances of Poria cocos powder are extracted, the rotating drive is reversed to drive the forward and reverse rotation adjustment component to operate. The forward and reverse rotation adjustment component drives the outer rotating stirring component to rotate forward, and at the same time drives the inner rotating stirring component to rotate forward. At this time, the rotation direction of the inner and outer rotating stirring components is the same. The rotating stirring component drives the mixed solvent inside the shell 1 to rotate slowly until the mixed solvent precipitates and separates into layers, so as to obtain a solution rich in Poria cocos polysaccharides, a solution rich in triterpenes, and Poria cocos powder precipitate.

[0045] Both of the above rotation methods can improve the uniformity of mixing between the Poria cocos powder and the mixed solvent inside the shell 1. However, when the rotation directions of the inner and outer rotating stirring components are the same, the mixed solution inside the shell 1 rotates in the same direction, making the movement of the mixed solution more regular and reducing the degree of disorder. In the later stage of extraction of the effective substances from the Poria cocos powder, the same-direction forward rotation operation can be adopted, which can reduce the energy consumption of the equipment and shorten the sedimentation and stratification time of the mixed solution and the Poria cocos powder mixture.

[0046] Specifically, the cross-section of the slot 21 is trapezoidal, meaning that one side of the slot 21 is deeper than the other side, and the locking post 22 is configured as follows:

[0047] When the locking pin 22 is located deep in the locking groove 21, the locking pin 22 rotates between the driven gear and the stirring shaft 19, and no power is transmitted between the driven gear and the stirring shaft 19;

[0048] When the locking pin 22 is located on the shallow side of the locking groove 21, the locking pin 22 is engaged between the driven gear and the stirring shaft 19, and the driven gear transmits power to the stirring shaft 19 through the locking pin 22.

[0049] Reference Figures 7-10 When motor 5 drives the drive gear 6 to rotate clockwise, the drive gear 6 drives the upper driven gear 8 to rotate counterclockwise. The upper driven gear 8 drives the lower driven gear 12 to rotate clockwise through the intermediate gear 10. At this time, the locking pin 22 in the slot 21 of the upper driven gear 8 slides from the deeper side to the shallower side and locks between the upper driven gear 8 and the stirring shaft 19. Meanwhile, the locking pin 22 in the slot 21 of the lower driven gear 12 slides from the shallower side to the deeper side and no longer locks between the lower driven gear 12 and the stirring shaft 19. At this time, the upper driven gear 8 drives the stirring shaft 19 to rotate counterclockwise through the locking pin 22. The intermediate gear 10 drives the gear ring 17 to rotate clockwise through the transmission shaft and the side gear 13. At this time, the rotation direction of the outer rotating stirring component is opposite to that of the inner rotating stirring component, which improves the mixing uniformity of the Poria cocos powder and the mixed solvent, so that the Poria cocos polysaccharides and triterpenes in the Poria cocos powder can be quickly and fully dissolved in the mixed solvent.

[0050] To prevent the locking post 22 from detaching from the slot 21, and to facilitate contact between the stirring shaft 19 and the locking post 22, the diameter of the locking post 22 is greater than the depth of either side of the slot 21.

[0051] Example 2:

[0052] This invention provides a device for the simultaneous extraction of Poria cocos polysaccharides and triterpenes, comprising:

[0053] The outer casing 1 is connected to a rotary drive component, which is a motor 5.

[0054] A forward / reverse adjustment assembly, disposed on the housing 1, includes a drive gear 6 connected to the rotary drive component, an upper connecting pipe 7 connected to the housing 1, and an upper driven gear 8 connected to the upper connecting pipe 7. A lower connecting pipe 11 is rotatably connected to the upper driven gear 8, and a lower driven gear 12 is rotatably connected to the lower connecting pipe 11. A connecting plate 9 is connected to the housing 1, and a drive shaft is rotatably connected to the connecting plate 9. One end of the drive shaft is connected to an intermediate gear 10 that meshes with the upper driven gear 8. The intermediate gear 10 meshes with both the upper driven gear 8 and the lower driven gear 12. The other end of the drive shaft is connected to a side gear 13. A base plate 14 is connected to the inner wall of the housing 1, and the base plate 14 is provided with:

[0055] The external rotating stirring assembly is connected to the side gear 13 and rotates under the action of the side gear 13;

[0056] The inner rotating stirring assembly is connected to the upper driven gear 8 or the lower driven gear 12. It includes a stirring shaft 19 inserted into the upper driven gear 8 and the lower driven gear 12. The inner walls of the upper driven gear 8 and the lower driven gear 12 are provided with slots 21. A locking post 22 is provided in the slot 21. The inner wall of the slot 21 away from the stirring shaft 19 is inclined. In order to facilitate the mutual interference between the inner and outer rotating stirring assemblies, the stirring axis of the outer rotating stirring assembly and the inner rotating stirring assembly overlaps with the axis of the outer shell 1.

[0057] As can be seen from the above, by setting a forward / reverse adjustment component, an outer rotating stirring component, and an inner rotating stirring component inside the outer shell 1, when the rotating drive rotates forward to drive the forward / reverse adjustment component to operate, the forward / reverse adjustment component drives the outer rotating stirring component to rotate in reverse, and at the same time drives the inner rotating stirring component to rotate forward. At this time, the rotation directions of the inner and outer rotating stirring components are opposite. The two rotating stirring components increase the degree of turbulent mixing between the mixed solvent and Poria cocos powder inside the outer shell 1, so that the Poria cocos powder is evenly dispersed in the mixed solvent, and the different liquid phases in the mixed solvent fully extract the Poria cocos polysaccharides and triterpenoids in the Poria cocos powder, thereby improving the extraction rate of effective substances from the Poria cocos powder.

[0058] After the effective substances of Poria cocos powder are extracted, the rotating drive is reversed to drive the forward and reverse rotation adjustment component to operate. The forward and reverse rotation adjustment component drives the outer rotating stirring component to rotate forward, and at the same time drives the inner rotating stirring component to rotate forward. At this time, the rotation direction of the inner and outer rotating stirring components is the same. The rotating stirring component drives the mixed solvent inside the shell 1 to rotate slowly until the mixed solvent precipitates and separates into layers, so as to obtain a solution rich in Poria cocos polysaccharides, a solution rich in triterpenes, and Poria cocos powder precipitate.

[0059] Both of the above rotation methods can improve the uniformity of mixing between the Poria cocos powder and the mixed solvent inside the shell 1. However, when the rotation directions of the inner and outer rotating stirring components are the same, the mixed solution inside the shell 1 rotates in the same direction, making the movement of the mixed solution more regular and reducing the degree of disorder. In the later stage of extraction of the effective substances from the Poria cocos powder, the same-direction forward rotation operation can be adopted, which can reduce the energy consumption of the equipment and shorten the sedimentation and stratification time of the mixed solution and the Poria cocos powder mixture.

[0060] Specifically, the cross-section of the slot 21 is trapezoidal, meaning that one side of the slot 21 is deeper than the other side, and the locking post 22 is configured as follows:

[0061] When the locking pin 22 is located deep in the locking groove 21, the locking pin 22 rotates between the driven gear and the stirring shaft 19, and no power is transmitted between the driven gear and the stirring shaft 19;

[0062] When the locking pin 22 is located on the shallow side of the locking groove 21, the locking pin 22 is engaged between the driven gear and the stirring shaft 19, and the driven gear transmits power to the stirring shaft 19 through the locking pin 22.

[0063] Reference Figures 7-10 When motor 5 drives the drive gear 6 to rotate clockwise, the drive gear 6 drives the upper driven gear 8 to rotate counterclockwise. The upper driven gear 8 drives the lower driven gear 12 to rotate clockwise through the intermediate gear 10. At this time, the locking pin 22 in the slot 21 of the upper driven gear 8 slides from the deeper side to the shallower side and locks between the upper driven gear 8 and the stirring shaft 19. Meanwhile, the locking pin 22 in the slot 21 of the lower driven gear 12 slides from the shallower side to the deeper side and no longer locks between the lower driven gear 12 and the stirring shaft 19. At this time, the upper driven gear 8 drives the stirring shaft 19 to rotate counterclockwise through the locking pin 22. The intermediate gear 10 drives the gear ring 17 to rotate clockwise through the transmission shaft and the side gear 13. At this time, the rotation direction of the outer rotating stirring component is opposite to that of the inner rotating stirring component, which improves the mixing uniformity of the Poria cocos powder and the mixed solvent, so that the Poria cocos polysaccharides and triterpenes in the Poria cocos powder can be quickly and fully dissolved in the mixed solvent.

[0064] To prevent the locking post 22 from detaching from the slot 21, and to facilitate contact between the stirring shaft 19 and the locking post 22, the diameter of the locking post 22 is greater than the depth of either side of the slot 21.

[0065] The external rotating stirring assembly includes a rotating ring 15 connected to the base plate 14, a mounting column 16 connected to the rotating ring 15, and a toothed ring 17 connected to the mounting column 16. The toothed ring 17 meshes with the side gear 13. An outer rotating plate 18 is connected to the mounting column 16. The outer rotating plate 18 is a counterclockwise spiral plate. The rotating toothed ring 17 drives the mounting column 16 and the rotating ring 15 to rotate, and then the mounting column 16 drives the outer rotating plate 18 to rotate.

[0066] The stirring shaft 19 is rotatably connected to the base plate 14. The inner rotating stirring assembly also includes a lower driven gear 12 connected to the upper end of the stirring shaft 19 and an inner rotating plate 20 connected to the stirring shaft 19. The lower driven gear 12 meshes with the intermediate gear 10. The inner rotating plate 20 is a spiral plate that spirals upward counterclockwise. The stirring shaft 19 will drive the inner rotating plate 20 to rotate.

[0067] The outer rotating plate 18 and the inner rotating plate 20 are staggered. The inner rotating plate 20 and the outer rotating plate 18 have the same spiral direction. When the inner rotating plate 20 and the outer rotating plate 18 rotate in opposite directions, the multiple staggered inner rotating plates 20 and outer rotating plates 18 can push the mixed solvent inside the shell 1 in different directions, so that the mixed solvents moving in different directions impact each other, further improving the uniformity of solvent mixing inside the shell 1.

[0068] The upper end of the outer shell 1 is connected to a feed pipe 2, through which the mixed solvent and Poria cocos powder can enter the outer shell 1. The lower end of the outer shell 1 is connected to a dispensing valve 3, and the dispensing valve 3 is connected to a discharge pipe 4. Multiple discharge pipes 4 are provided. After the mixed solvent inside the outer shell 1 has finished mixing and extracting the Poria cocos powder and has been allowed to stand and separate into layers, the dispensing valve 3 can be controlled to open one discharge pipe 4 to discharge the lower layer solution in the outer shell 1. Then, the dispensing valve 3 can be controlled to open another discharge pipe 4 to discharge the upper layer solution in the outer shell 1.

[0069] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
