Description

Technical Field

[0001] This invention belongs to the field of agricultural product component extraction technology, specifically relating to an extraction device for solanine from potato tubers. Background Technology

[0002] Solanine can affect and reduce the expression of proteins on tumor cell membranes, such as reducing sialic acid content, inhibiting ATPase activity, and downregulating N-acetyltransferase expression, thereby reducing tumor cell membrane fluidity and inhibiting the metabolic growth of tumor cells.

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] like Figures 1 to 8 As shown, the present invention provides a technical solution: an extraction device for solanine in potato tubers, comprising a main tank 1, an extraction tank 3 disposed inside the main tank 1, a mounting frame 4 fixedly connected to the top of the main tank 1, a plurality of storage tanks 5 fixedly installed on the inner wall of the mounting frame 4, a discharge pipe 6 fixedly connected to the bottom of each storage tank 5, the outlet end of each discharge pipe 6 being located above the top opening end of the extraction tank 3, a base plate 8 fixedly connected to the bottom opening end of the extraction tank 3, a liquid outlet pipe disposed at the bottom of the base plate 8, a plurality of sets of drainage holes 7 evenly arranged on the outer wall of the extraction tank 3, a plurality of baffle plates 9 slidably connected to the outer wall of the extraction tank 3, the plurality of baffle plates 9 being located on one side of the plurality of sets of drainage holes 7, a stirring assembly disposed inside the extraction tank 3, a side-moving assembly disposed at the stirring assembly, the side-moving assembly being used to drive the plurality of baffle plates 9 to slide simultaneously along the outer wall of the extraction tank 3.

[0031] During operation: When extracting solanine from potato chunks, they need to be crushed into small pieces. Then, the potato chunks and extraction solvent are added together into the tank for mixing and reaction to extract and separate solanine from the solid. The extraction solvent includes ethanol solution, acetonitrile solution and glacial acetic acid solution.

[0032] First, the prepared raw materials (potato chunks and extraction solvent) are added into the extraction tank 3 through the storage tank 5 and the discharge pipe 6. The stirring assembly is started to fully mix and react the raw materials to generate a mixed solution containing solanine. In the initial state, multiple baffles 9 are located on one side of multiple sets of drainage holes 7, temporarily blocking the drainage holes 7. This ensures that the extraction solvent and potato chunks can be in the extraction tank 3 at the same time under the action of the stirring assembly, so that the raw materials can fully contact and react. After the reaction is completed, the stirring assembly stops moving, and the valve on the discharge pipe at the bottom of the base plate 8 is opened. The mixed solution flows out to the bottom of the main tank 1 under the action of gravity, thus completing the overall extraction process.

[0033] Additionally, after the reaction, some of the mixed solution may remain between potato pieces and on the stirring device. This solution will not flow out after the valve on the outlet pipe is opened. At this time, the side-shifting component moves, and after the side-shifting component completes its movement, the stirring component moves. Under the driving force of the stirring component, the side-shifting component will cause multiple baffles 9 to slide along the outer wall of the extraction tank 3 at the same time. In this way, the multiple baffles 9 will no longer block the drain hole 7. When the stirring component continues to move, it will drive the entire extraction tank 3 to rotate through the baffles 9. Under the centrifugal force generated by the rotation of the extraction tank 3, the mixed solution remaining on the surface of the solid material and in the gaps of the stirring device will be efficiently thrown out through the drain hole 7. The thrown solution will slide down along the inner wall of the main tank 1 and be collected together with the extracted mixed solution for subsequent distillation.

[0034] Through the above embodiments, when the baffle plate 9 blocks the drain hole 7, the extraction solvent and potato pieces can react fully under the action of the stirring component. By controlling multiple baffle plates 9 to slide along the outer wall of the extraction tank 3 through the side-moving component, the drain hole 7 can be dynamically opened and closed. In conjunction with the stirring component driving the tank to rotate, the residual solution is efficiently discharged through the drain hole 7 under the action of centrifugal force, avoiding the residue of mixed solution and improving the extraction yield of solanine.

[0035] like Figures 4 to 6 As shown, the stirring assembly includes a motor 13, which is fixedly mounted on the top of the mounting frame 4. The output shaft of the motor 13 is fixedly connected to a rotating shaft 14, which passes through the inner wall of the mounting frame 4 and is rotatably connected to the mounting frame 4. A stirring mechanism 15 is fixedly connected to the outer wall of the rotating shaft 14, and the stirring mechanism 15 is located inside the extraction tank 3.

[0036] During operation: After adding raw materials into the extraction tank 3, the motor 13 is started, and its output shaft drives the rotating shaft 14 to rotate. The rotating shaft 14 drives the stirring mechanism 15 to rotate, so that the potato pieces and the extraction solvent are fully mixed and reacted. After the rotating shaft 14 drives the offset component to move multiple baffles 9 along the outer wall of the extraction tank 3, when the motor 13 continues to start, it will drive the entire extraction tank 3 to rotate together through the rotating shaft 14. At this time, the drain hole 7 is in the open stage, and the residual mixed solution can be thrown out along the inner hole of the drain hole 7, thereby completing the treatment of the residual solution.

[0037] like Figures 5 to 6 As shown, the inner side of the baffle plate 9 is arc-shaped and fits the outer wall of the extraction tank 3. Multiple fixing plates 11 are fixedly connected to the outer wall of the extraction tank 3. Multiple side connecting blocks 10 are fixedly connected to one side of the baffle plate 9. Torsion spring rods 12 are fixedly connected between the fixing plates 11 and the multiple side connecting blocks 10.

[0038] During operation: After the lateral displacement component completes its initial displacement, the motor 13 drives the rotating shaft 14 to rotate continuously. At this time, the lateral displacement component continuously squeezes the outside of the baffle plate 9, forcing the baffle plate 9 to slide laterally along the arc-shaped guide rail on the outer wall of the extraction tank 3. Simultaneously, the torsion spring rod 12 is compressed to generate elastic energy. When the baffle plate 9 moves to the critical position where the drain hole 7 is fully exposed, the torsion spring rod 12 reaches the maximum deformation threshold. At this time, the continuous squeezing force of the rotating shaft 14 is transmitted to the outer wall of the extraction tank 3 through the rigid connection between the side block 10 of the baffle plate 9 and the fixed plate 11, forming a torque that drives the extraction tank 3 to rotate at high speed around the central axis.

[0039] like Figures 7 to 8 As shown, a connecting block 23 is fixedly connected to one side of each of the multiple blocking plates 9, and a push plate 24 is fixedly connected to one side of each connecting block 23. The lateral movement component includes a polygonal frame 18, which is fixedly installed on the outer wall of the rotating shaft 14. Multiple inner rods 19 are inserted into the inner wall of the polygonal frame 18, and a push rod 22 is provided at the bottom of each inner rod 19. A pressing component is provided above the polygonal frame 18, which is used to squeeze the multiple inner rods 19 to move downward along the inner wall of the polygonal frame 18.

[0040] During operation: Under normal conditions, when the pressing component is not activated, the pusher rod 22 is located above the pusher plate 24 and does not contact it. When the rotating shaft 14 drives the polygonal frame 18 to rotate, the pusher rod 22 and the pusher plate 24 do not interact. After the first stirring is completed and the mixed solution is discharged from the bottom of the extraction tank 3, the pressing component presses down multiple inner rods 19 simultaneously and drives the pusher rod 22 to move down along the inner wall of the polygonal frame 18 to the side of the pusher plate 24. At this time, the motor 13 is restarted to drive the rotating shaft 14 to continue rotating. During the revolution around the extraction tank 3, the pusher rod 22 squeezes the adjacent pusher plates 24 in sequence. The thrust is transmitted to the blocking plate 9 through the connecting block 23 so that it moves laterally along the outer wall of the extraction tank 3 to open the drain hole 7. When the pusher rod 22 continues to apply pressure to the deformation limit of the torsion spring rod 12, the squeezing force is converted into torque through the fixed plate 11 to drive the entire extraction tank 3 to rotate around the axis.

[0041] like Figures 7 to 8 As shown, the bottom of each inner insert rod 19 is fixedly connected to an arc-shaped slide block 21, the inner wall of each arc-shaped slide block 21 is fixedly connected to an arc-shaped slide rod 27, the outer wall of each arc-shaped slide rod 27 is slidably connected to an inner slider 26, and multiple inner sliders 26 are slidably connected to multiple arc-shaped slide blocks 21 respectively. The bottom of the inner slider 26 is fixedly connected to the top of the push rod 22.

[0042] During operation: After the first mixing is completed, the push rod 22 may stop directly above the push plate 24. When the pressing component is activated to move the push rod 22 downward, the push rod 22 will be restricted by the push plate 24. The pressing component cannot smoothly move the push rod 22 to the side of the push plate 24, thus preventing the blocking plate 9 from shifting laterally due to the pressure between the push rod 22 and the push plate 24. However, the inner slider 26 and the arc-shaped slider 27 prevent the push rod 22 from stopping directly above the push plate 24. When the pusher is directly above the pusher plate 24, the pusher rod 22 will be squeezed by the top surface of the pusher plate 24 when it moves down. At this time, the inner slider 26 will slide laterally along the preset arc path under the dual guidance of the arc-shaped slide block 21 and the arc-shaped slide rod 27, so that the pusher rod 22 will deflect to the side in the process of vertical pressing, thereby bypassing the vertical blocking surface of the pusher plate 24 and finally positioning itself to the side, ensuring that the pusher rod 22 can smoothly squeeze the pusher plate 24 to trigger the lateral movement of the blocking plate 9 and the rotation of the tank when it rotates laterally.

[0043] It should be noted that if the push stick 22 is not stopped directly above the push plate 24, as the push stick 22 continues to rotate with the rotating shaft 14 and presses the push plate 24, the push stick 22 and the inner slider 26 will first slide along the inner wall of the arc-shaped slide block 21 to the maximum stroke position. This sliding process will not affect the final pressing effect on the push plate 24, and can still ensure that the blocking plate 9 completes the lateral movement as designed.

[0044] like Figure 5 and Figure 8As shown, the top surface of the push plate 24 is all curved.

[0045] During operation: Since the top surface of the push plate 24 is all curved, when the push stick 22 stops directly above the push plate 24 due to the initial position deviation, the curved top surface can transform the rigid contact in the vertical direction into a progressive inclined extrusion during the pressing process, so that the inner slider 26 slides along the curved slider 27. The lifting force of the curved surface can be decomposed into vertical and horizontal components, and the push stick 22 can smoothly complete the lateral deflection.

[0046] like Figure 4 and Figure 7 As shown, the pressing assembly includes multiple telescopic rods 16, all of which are fixedly connected to the bottom of the mounting frame 4. A pressing ring 17 is fixedly connected between the bottom ends of the mounting frame 4. A pressing block 20 is fixedly connected to the top of each inner rod 19, and the top of each pressing block 20 is in contact with the bottom surface of the pressing ring 17.

[0047] During operation: When the pressing component is working, multiple telescopic rods 16 synchronously extend and retract, driving the mounting frame 4 to move the pressing ring 17 vertically. The vertical pressure is evenly transmitted to the inner rod 19 through the top pressing block 20, so that the ball pusher 22 can simultaneously achieve obstacle avoidance deflection or direct positioning and squeezing during axial movement, thereby enabling the ball pusher 22 to eventually move down to the side of the push plate 24.

[0048] like Figures 7 to 8 As shown, the outer wall of the inner insert rod 19 is provided with a second spring 29, and the two ends of the second spring 29 are fixedly connected to the bottom of the top pressure block 20 and the top of the polygonal frame 18, respectively. The outer wall of the arc-shaped slide rod 27 is provided with a first spring 28, and the two ends of the first spring 28 are fixedly connected to one side of the inner slider 26 and the inner wall of the arc-shaped slide seat 21, respectively.

[0049] During operation: When the top pressure block 20 is squeezed and moved downward by the lower pressure ring 17, the second spring 29 will be compressed and deformed. When the inner slider 26 slides along the inner wall of the arc-shaped slide block 21, the first spring 28 will also be compressed and deformed. After the rotation effect of the extraction tank 3 is finally completed, the lower pressure assembly is reset. At this time, the top pressure block 20 is reset first under the action of the second spring 29. During the reset, the pusher rod 22 is disengaged from the contact of the pusher plate 24. During the process, the inner slider 26 and the pusher rod 22 are reset under the action of the first spring 28. At this time, the blocking plate 9 will be reset under the action of the torsion spring rod 12 and return to the position of blocking the drain hole 7.

[0050] like Figure 2 , Figure 3 and Figure 5As shown, an inner groove slip ring 31 is fixedly connected to the inner wall of the main tank 1, and multiple sliding blocks 30 are slidably connected to the inner wall of the inner groove slip ring 31. One side of each sliding block 30 is fixedly connected to the outer wall of the base plate 8. A collection funnel 32 is fixedly connected to the inner wall of the main tank 1, and the collection funnel 32 is located below the extraction tank 3.

[0051] During operation: Through the inner groove slip ring 31 and the sliding block 30, when the extraction tank 3 rotates, the sliding block 30 will move along the inner groove wall of the inner groove slip ring 31, which ensures the stability of the rotation of the extraction tank 3. The collection funnel 32 is used to collect the mixed solution extracted in the first extraction and the solution ejected by centrifugation in the second extraction. The solution ejected by centrifugation in the second extraction will eventually slide along the inner wall of the main tank 1 to the surface of the collection funnel 32.

[0052] like Figures 1 to 2 As shown, a detachable evaporator 2 is provided at the bottom of the main tank 1. A heating plate 33 is provided on the top surface of the inner wall of the evaporator 2. A receiving plate 25 is fixedly connected to one side of the evaporator 2. An alkaline liquid storage pipe 34 is provided above the receiving plate 25. A dripping pipe 35 is fixedly connected to the bottom of the alkaline liquid storage pipe 34. The open end of the dripping pipe 35 is located inside the evaporator 2.

[0053] During operation: The extracted mixed solution will eventually drip along the arc surface of the collecting funnel 32 onto the surface of the heating plate 33. At this time, the alkaline solution in the alkaline storage tube 34 is added to the surface of the heating plate 33 through the drip tube 35. With the heating function of the heating plate 33, the alkaline solution reacts with the mixed solution on the surface of the heating plate 33. The reaction produces gas that flows out from the top of the main tank 1, and the final solanine product is obtained. The product on the surface of the heating plate 33 is collected by disassembling the evaporation tank 2.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
