Description

Technical Field

[0001] The present invention belongs to the technical field of anthocyanin extraction and processing, and relates to a high-purity black wolfberry anthocyanin purification device. Background Art

[0002] The content of anthocyanin in black wolfberry is very high, several times that of ordinary foods. It has the reputation of the king of anthocyanins and is the most powerful free radical scavenger discovered so far. It is widely used in the prevention and treatment of cardiovascular and cerebrovascular diseases, can inhibit free radicals in blood vessels, and has the functions of anti-aging, antioxidant, and preventing arteriosclerosis. When extracting and processing anthocyanins, operations such as crushing, squeezing, and filtering of black wolfberry are required.

[0003] A high-purity black wolfberry anthocyanin purification device and its purification method disclosed in Chinese Patent CN115138424B include a base, a large gear, a small gear, a cylinder, an annular plate, a collection hood, and a driving motor. A limiting pin is fixed radially on the outer end of the output shaft of the driving motor. Corresponding card slots are respectively provided on the outer surfaces of the two transfer disks. When the driving motor slides to both sides of the U-shaped chute, the limiting pin can be respectively inserted and matched with the corresponding card slots of the transfer disks, so as to realize the transmission switching of the driving motor between the large gear and the small gear.

[0004] When separating and filtering with this device, it is necessary to remove the cover plate to expose the long strip filter screen, and then the long strip filter screen is separated and filtered under the action of centrifugation. During filtration, only the solution is discharged, and the liquid contained in the filter residue after filtration is not squeezed out, resulting in waste. Moreover, the filter residue after filtration remains in the cylinder, which is not convenient for direct cleaning.

[0014] Further, the elastic filter element includes a rubber ring. The rubber ring is sleeved on the outer surface of the end of the thin cylinder, and the end of the rubber ring is fixedly connected to the outer surface of the thin cylinder. The rubber ring is in sealing sliding fit with the inner wall of the thick cylinder; A plurality of elastic members are evenly fixedly connected to one side of the rubber ring, and the other ends of the elastic members are fixedly connected to the end face of the thick cylinder; Elastic membranes are fixedly connected to both sides of each elastic member, and filter cloths are fixedly connected between adjacent two elastic membranes.

[0019] 4. The high-purity black wolfberry anthocyanin purification device is provided with an elastic filtering component and a crushing component on the thin cylinder and the thick cylinder, which can directly perform operations such as crushing, mixing, and separation filtering, without the need for the raw material to be transferred between different devices multiple times, which is more time-saving and labor-saving.

A gear 21 is fixedly connected to the end of the output shaft of the fourth motor 20. The output shaft of the fourth motor 20 drives the gear 21 to rotate.

[0030] A toothed ring 19 is fixedly connected to the side of the first rotating plate 4 away from the second rotating plate 5, and the toothed ring 19 meshes with the gear 21. When the gear 21 rotates, it will drive the toothed ring 19 to rotate, driving the first rotating plate 4 to rotate, and making the electric push rods 12 and the second rotating plate 5 rotate.

[0031] The same elastic filter element is fixedly connected to the ends of the thin cylinder 7 and the thick cylinder 6 close to each other.

[0032] The elastic filter element includes a rubber ring 8, and the rubber ring 8 is sleeved on the outer surface of the end of the thin cylinder 7. The end of the rubber ring 8 is fixedly connected to the outer surface of the thin cylinder 7, so that the rubber ring 8 can be turned over outside the thin cylinder 7. The rubber ring 8 is in sealing sliding fit with the inner wall of the thick cylinder 6, and the connection between the thick cylinder 6 and the thin cylinder 7 is sealed through the rubber ring 8.

[0033] A plurality of elastic members 9 are uniformly and fixedly connected to one side of the rubber ring 8, and the other ends of the elastic members 9 are fixedly connected to the end surface of the thick cylinder 6. When the elastic members 9 are not stressed, the elastic members 9 are in a vertical state, that is, the elastic members 9 are in a straight strip shape. The elastic members 9 are made of elastic materials, can be stretched and deformed when stressed, and can automatically return to their original state when not stressed.

[0034] On both sides of each elastic member 9, there are elastic membranes 11 fixedly connected. The elastic membrane 11 is a soft and transparent film that can deform together with the elastic member 9. A filter cloth 10 is fixedly connected between two adjacent elastic membranes 11. One end of the elastic membrane 11 and the filter cloth 10 is fixedly connected to one side of the rubber ring 8, and the other end of the elastic membrane 11 and the filter cloth 10 is fixedly connected to the end face of the thick cylinder 6. When the elastic member 9 is stressed, it will drive the filter cloth 10 and the elastic membrane 11 to move together, and the filter cloth 10 has a filtering effect.

[0035] At the ends of the thin cylinder 7 and the thick cylinder 6 that are away from each other, there are a sealing assembly and a crushing assembly respectively.

[0036] The crushing assembly includes a second motor 15. Fixing members 14 are fixedly connected to the inner walls of the thin cylinder 7 and the thick cylinder 6, and the second motor 15 is fixedly connected to the middle of the fixing member 14. The output end of the second motor 15 is fixedly connected to a rotating shaft, and a number of crushing blades 16 are evenly fixedly connected to the outer surface of the rotating shaft.

Third motors 18 are fixedly connected to the end faces of the thin cylinder 7 and the thick cylinder 6, and the lid 17 is fixedly connected to the end of the output shaft of the corresponding third motor 18. The output shaft of the third motor 18 drives the lid 17 to rotate.

[0038] One of the lids 17 is in sealed sliding fit with the end face of the thin cylinder 7, and the other lid 17 is in sealed sliding fit with the end face of the thick cylinder 6. So as to seal the thin cylinder 7 or the thick cylinder 6 through the lid 17 and process the black goji berries inside the thin cylinder 7 and the thick cylinder 6.

[0039] The cross-sectional shape of the inner wall of the connecting cylinder 2 is V-shaped, and a first liquid discharge port 22 is provided in the middle of the side of the connecting cylinder 2. So as to facilitate the discharge of the liquid in the connecting cylinder 2. A second liquid discharge port 23 is provided on the second rotating plate 5, and valves are provided on both the first liquid discharge port 22 and the second liquid discharge port 23.

[0040] A robotic arm 24 is arranged outside the fixing frame 1. The movable end of the robotic arm 24 is fixedly installed with a mounting plate 25, and a feeding pipe 26, a liquid injection pipe 27, and a flushing pipe 28 are fixedly penetrated through the mounting plate 25. The feeding pipe 26 is connected to a box containing black goji berries, the liquid injection pipe 27 is connected to a box containing ethanol solution, and the flushing pipe 28 is connected to a box containing water. The diameters of the feeding pipe 26, the liquid injection pipe 27, and the flushing pipe 28 are all smaller than the diameter of the thick cylinder 6, so as to facilitate the feeding of materials into the thick cylinder 6.

[0041] Working principle: In the initial state, one end of the thin cylinder 7 extends into the thick cylinder 6. The rubber ring 8 seals the connection between the thin cylinder 7 and the thick cylinder 6, and the elastic member 9 is in a bent annular state. The elastic member 9 props up the filter cloth 10 and the elastic membrane 11. At this time, the elastic member 9, the filter cloth 10, and the elastic membrane 11 enclose a cavity. This cavity is not connected to the thin cylinder 7 and the thick cylinder 6.

[0042] Start the first motor 3 to drive the connecting cylinder 2 to rotate. Rotate the thick cylinder 6 and the thin cylinder 7 to the vertical state, and the thick cylinder 6 is located above.

[0043] Start the third motor 18 on the thick cylinder 6. The third motor 18 drives the cover 17 to rotate. The cover 17 rotates away from the thick cylinder 6 to open the end of the thick cylinder 6.

[0044] Move the mounting plate 25 through the robotic arm 24, and insert the bottom end of the feeding pipe 26 into the thick cylinder 6. Feed the black goji berries into the thick cylinder 6, and the black goji berries will fall into the thin cylinder 7. After feeding, the robotic arm 24 removes the feeding pipe 26.

[0045] The third motor 18 on the thick cylinder 6 drives the cover 17 to continue rotating, so that the cover 17 seals the end of the thick cylinder 6.

[0046] Start the second motor 15 in the thick cylinder 6 and the thin cylinder 7. The second motor 15 drives the rotating shaft and the crushing blade 16 to rotate, so that the crushing blade 16 crushes the black goji berries.

[0047] Start the first motor 3. The output shaft of the first motor 3 rotates intermittently, so that the connecting cylinder 2 rotates intermittently.

[0048] When the thick cylinder 6 and the thin cylinder 7 rotate to the vertical state and the thick cylinder 6 is located below the thin cylinder 7. The black goji berries in the thin cylinder 7 will fall into the thick cylinder 6, and the crushing blade 16 in the thick cylinder 6 crushes the black goji berries. After the black goji berries are crushed inside the thick cylinder 6 for a period of time, the connecting cylinder 2 continues to rotate.

[0049] When the thick cylinder 6 and the thin cylinder 7 rotate to the vertical state and the thin cylinder 7 is located below the thick cylinder 6, the black goji berries will fall from the thick cylinder 6 into the thin cylinder 7, and the crushing blade 16 in the thin cylinder 7 crushes the black goji berries.

[0050] Make the connecting cylinder 2 rotate 180 degrees and then stop for a period of time, with the thin cylinder 7 and the thick cylinder 6 located above in turn. So as to facilitate the crushing blade 16 to crush the black goji berries during the falling process, avoid the accumulation of the black goji berries at the bottom and the difficulty of contact with the crushing blade 16 for crushing, and make the crushing more thorough.

[0051] After crushing, rotate the thick cylinder 6 and the thin cylinder 7 to the vertical state, and the thick cylinder 6 is located above. At this time, the crushed black goji berries are located in the thin cylinder 7.

[0052] Open the lid 17 on the thick cylinder 6, insert the liquid injection tube 27 into the thick cylinder 6 through the robotic arm 24, introduce the ethanol solution into the thick cylinder 6, and the ethanol solution enters the thin cylinder 7 and contacts the black goji berries. Remove the liquid injection tube 27 and let the lid 17 continue to seal the thick cylinder 6.

[0053] Start the second motor 15 to make the crushing blade 16 continue to rotate. While continuing to crush, the crushing blade 16 can mix the black goji berries and the ethanol solution. The output shaft of the first motor 3 rotates intermittently, driving the black goji berries and the ethanol solution to move, making the mixing effect better.

[0054] The ethanol solution serves as an eluent, which helps to improve the purity of anthocyanin and desorbs it from the resin through the elution process, thus achieving the purpose of high purity.

[0055] After mixing is completed, the first motor 3 rotates the thick cylinder 6 and the thin cylinder 7 to an inclined state, with the thin cylinder 7 at a higher position. At this time, all the solution is in the thick cylinder 6, and then soak for a period of time to allow the anthocyanin to fully dissolve in the solvent.

[0056] Start the electric push rod 12. The electric push rod 12 pushes the connecting rod 13, and the connecting rod 13 drives the thin cylinder 7 to move. The thin cylinder 7 drives the rubber ring 8 to move towards the outside of the thick cylinder 6, and the rubber ring 8 drives one end of the elastic member 9, the filter cloth 10, and the elastic membrane 11 to move, so that the cavity formed by the elastic member 9, the filter cloth 10, and the elastic membrane 11 communicates with the thin cylinder 7 and the thick cylinder 6.

[0057] When the rubber ring 8 drives one end of the elastic member 9 to move, the thrust on the elastic member 9 decreases, causing the elastic member 9 to automatically return to the vertical state under its own elasticity. Due to the restriction of the rubber ring 8, the elastic member 9 remains in a bent and deformed state.

[0058] After there is an opening between the rubber ring 8 and the thick cylinder 6, the first motor 3 drives the connecting cylinder 2 to rotate slowly, making the thick cylinder 6 and the thin cylinder 7 rotate slowly. Until the thick cylinder 6 is in an inclined state at a higher position, so that the solution in the thick cylinder 6 will all flow into the cavity formed by the elastic member 9, the filter cloth 10, and the elastic membrane 11.

[0059] The electric push rod 12 pulls the end of the thin cylinder 7 towards the inside of the thick cylinder 6 through the connecting rod 13, and the rubber ring 8 drives one end of the elastic member 9, the filter cloth 10, and the elastic membrane 11 to move. The elastic member 9 continues to be compressed until the rubber ring 8 reseals the connection between the thin cylinder 7 and the thick cylinder 6.

[0060] Start the fourth motor 20. The fourth motor 20 drives the gear 21 to rotate. The gear 21 drives the toothed ring 19 to rotate, making the first rotating plate 4 rotate, and the electric push rod 12 and the second rotating plate 5 rotate.

[0061] The first rotating plate 4 and the second rotating plate 5 drive the thick cylinder 6 and the thin cylinder 7 to rotate, causing the elastic member 9, the filter cloth 10, and the elastic film 11 to rotate. This drives the solution to rotate, and the filter cloth 10 performs filtration. The filtered solution enters the connecting cylinder 2, and the filtered waste residue remains in the cavity formed by the elastic member 9, the filter cloth 10, and the elastic film 11.

[0062] During the filtration process, the electric push rod 12 pushes the thin cylinder 7 towards the inside of the thick cylinder 6. This causes the rubber ring 8 to pull the elastic member 9 to continue deforming, reducing the cavity formed by the elastic member 9, the filter cloth 10, and the elastic film 11. As a result, the filter residue in the cavity will be compressed, and the filter cloth 10 will continue to squeeze out the solution.

[0063] After the filtration is completed, the valve on the first drain port 22 is opened to collect the solution.

[0064] When cleaning the filter residue, the first motor 3 rotates the thick cylinder 6 and the thin cylinder 7 to the vertical state, with the thick cylinder 6 positioned above. Two third motors 18 are started to open the lids 17 on the thick cylinder 6 and the thin cylinder 7.

[0065] The electric push rod 12 pushes the thin cylinder 7 towards the end away from the thick cylinder 6. This causes the elastic member 9 to gradually return to the vertical state. The elastic member 9 will pull the rubber ring 8 to turn over, moving the rubber ring 8 to the top of the thin cylinder 7, and the elastic member 9 pulls the filter cloth 10 and the elastic film 11 to the vertical state.

[0066] At this time, the filter residue on the filter cloth 10 and the elastic film 11 will fall downward and be discharged through the bottom end of the thin cylinder 7.

[0067] The flushing pipe 28 is inserted into the thick cylinder 6 through the robotic arm 24, and water is drained into the thick cylinder 6. The water will flush the crushing blade 16 and the filter cloth 10, taking away the filter residue, and the flushing water is discharged through the lid 17 at the bottom end of the thin cylinder 7.

[0068] During the flushing process, some water will enter the connecting cylinder 2 through the filter cloth 10. Open the valve on the second drain port 23 to drain the water.

[0069] After the flushing is completed, the electric push rod 12 pulls the thin cylinder 7 towards the inside of the thick cylinder 6. This causes the rubber ring 8 to turn over and return to the initial state, thereby sealing the connection between the thin cylinder 7 and the thick cylinder 6. The elastic member 9 is in a bent annular state for easy reuse.
