Description

Technical Field

[0001] This application relates to the technical field of capsaicin extraction. Specifically, it relates to a device and method for crude extraction of capsaicin. Background Art

[0002] When extracting capsaicin, the organic solvent extraction method is usually adopted. However, in the prior art, usually, the pepper is first crushed by a crushing device and then put into an extraction tank for solution extraction. This method increases the number of devices required for capsaicin extraction, occupies production space, and increases equipment costs.

[0003] In the prior art, there are also devices that integrate crushing and extraction, which crush and perform solution extraction on peppers in the same device. For example, the capsaicin preparation device, preparation process, and its application disclosed in Publication (Announcement) No. CN116236812B. During the extraction process, it is inevitable that the pepper crushing section will also enter the ethanol solution. In this way, it is inevitable that pepper residues will remain on the inner wall of the crushing section cylinder during the crushing of peppers, and due to moisture, the remaining pepper residues cannot enter the solution extraction section. Thus, the effect of the entire capsaicin extraction will be affected. Summary of the Invention

[0004] This application aims to solve at least one of the technical problems existing in the prior art. For this purpose, this application provides a device for crude extraction of capsaicin, including an outer cylinder, a feeding component, and a crushing component. An inner cylinder is coaxially and fixedly connected inside the outer cylinder. The bottom end of the outer cylinder is coaxially connected to a solution cylinder. A reaction cylinder is coaxially sleeved outside the outer cylinder and is used to store anhydrous ethanol. A filter cylinder is coaxially embedded in the reaction cylinder. The filter cylinder is in contact with the reaction cylinder. The filter cylinder is coaxially sleeved on the inner cylinder. The filter cylinder is in contact with the inner cylinder. The upper end of the reaction cylinder is coaxially connected to a condensation cylinder. The condensation cylinder is communicated with the reaction cylinder. A siphon tube is communicated between the reaction cylinder and the filter cylinder. A plurality of holes for passing pepper residues are circumferentially and uniformly arranged at the top of the side wall of the inner cylinder. The solution cylinder and the reaction cylinder are externally connected to a heating device. The outer cylinder is inserted into the filter cylinder, and a feeding channel is formed between the outer cylinder, the inner cylinder, and the filter cylinder. The feeding component includes a feeding cylinder, a feeding hopper, and a motor. The feeding cylinder is coaxially and rotatably inserted into the inner cylinder and extends out of the outer cylinder. The feeding hopper is coaxially arranged at one end of the feeding cylinder extending out of the outer cylinder and is fixedly connected to the outer cylinder. The motor is fixedly connected to the outer cylinder and provides power for the feeding cylinder to rotate. The crushing component includes a spiral conveying blade and a crushing part. The spiral conveying blade is coaxially sleeved on the feeding cylinder. The crushing part is fixedly connected to the side wall of the spiral conveying blade and is in clearance fit with the inner wall of the inner cylinder.

[0005] Preferably, the holes provided at the top of the side wall of the inner cylinder are filter holes, the filter holes are inclined, one end of the filter hole facing the inside of the inner cylinder is higher than the end of the filter hole facing the outside of the inner cylinder, and the top end of the spiral conveyor blade is within the height range of the filter hole on the side wall of the inner cylinder.

[0006] Preferably, a plurality of steam pipes are uniformly communicated circumferentially between the solution cylinder and the condensation cylinder.

[0007] Preferably, the reaction cylinder and the filter cylinder are both annularly arranged, and the cross section of the filter cylinder is U-shaped.

[0008] Preferably, a plurality of conduits are uniformly communicated circumferentially at the bottom end of the condensation cylinder, and the conduits extend to the inner bottom of the filter cylinder.

[0009] Preferably, a bevel gear ring is coaxially sleeved at one end of the feeding cylinder extending out of the outer cylinder, and a notch is provided at one end of the feeding cylinder located at the inner bottom of the inner cylinder.

[0010] Preferably, a plurality of support rods are uniformly fixed on the periphery of the feeding hopper, and the plurality of support rods are fixed to the outer cylinder.

[0011] Preferably, a bevel gear is key-connected to the output end of the motor, and the bevel gear meshes with the bevel gear ring.

[0012] Preferably, a groove is provided on the side wall of the spiral conveyor blade.

[0013] Preferably, the crushing member includes a fixing strip embedded in the groove and a plurality of crushing teeth uniformly fixed to the fixing strip, and the plurality of crushing teeth are spaced apart.

[0014] On the other hand, the present application further provides a method for crude extraction of capsaicin, including the following steps: S1, crushing the chili peppers. Put the chili peppers into the feeding hopper, enter the inner cylinder through the feeding cylinder, start the motor to rotate the feeding cylinder, and use the centrifugal force generated by the rotation to throw the chili peppers out from the bottom end of the feeding cylinder. At the same time, the spiral conveyor blade rotates driven by the feeding cylinder, and conveys the chili peppers located at the bottom of the inner cylinder upward. During the conveying process, use the crushing member to complete the crushing operation of the chili peppers; S2, conveying the chili pepper powder. The chili peppers are axially conveyed by the spiral conveyor blade to the hole at the top end of the inner cylinder for the chili pepper powder to pass through. The chili pepper powder smaller than the inner diameter of the hole after crushing can pass through the hole and enter the channel between the outer cylinder and the side wall of the inner cylinder. The larger powder still remains in the inner cylinder and continues to be crushed by the crushing member until it meets the standard. The chili pepper powder entering the channel between the outer cylinder and the inner cylinder falls to the inner bottom end of the filter cylinder; S3. Deliver absolute ethanol, vaporize the absolute ethanol inside by using the heating equipment externally connected to the solution cylinder, and let it enter the condensation cylinder through the steam pipe to form condensate. The condensate drips onto the crushed chili peppers in the filter cylinder through the conduit to dissolve the capsaicin in the crushed chili peppers. S4. Solution reflux. As more and more absolute ethanol condenses in the filter cylinder, when the liquid level height exceeds the siphon pipe, the siphon pipe will generate a siphon effect to suck back the absolute ethanol dissolved with capsaicin in the filter cylinder into the solution cylinder. And the solution cylinder is continuously heated, and the absolute ethanol inside continues to vaporize and is delivered to the condensation cylinder, that is, step S3 continues, so as to form multiple times of solution reflux. S5. Separate capsaicin. Collect the solution after multiple refluxes in the solution cylinder, evaporate the absolute ethanol under reduced pressure at a low temperature to separate capsaicin from the absolute ethanol.

[0015] The beneficial effects of the present invention are as follows: 1. By using the feeding channel formed between the inner cylinder, the outer cylinder and the filter cylinder, the crushed chili peppers in the inner cylinder can and can only enter between the outer cylinder and the inner cylinder from the top of the side wall of the inner cylinder and fall into the filter cylinder. In this way, the absolute ethanol entering the reaction cylinder and the filter cylinder from the condensation cylinder can and can only react with the crushed chili peppers in the filter cylinder, realizing dry-wet separation, avoiding the adhesion of the crushed chili peppers in the inner cylinder in the inner cylinder, resulting in a decrease in the utilization rate of chili peppers and affecting the extraction efficiency of capsaicin. 2. The spiral conveying blade can convey the chili peppers conveyed from the feeding cylinder direction from the bottom end to the top end of the inner cylinder. At the same time, the crushing parts installed on the side wall of the spiral conveying blade rotate along with the spiral conveying blade to crush the chili peppers, realizing multi-process work in the same equipment, saving the space occupied by the equipment, reducing the cost of the equipment, and further improving the production efficiency.

[0020] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application.

[0021] To make the purpose, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0022] Embodiment 1, as Figures 1 - 16 shown, a capsaicin crude extraction device according to an embodiment of the present application includes an outer cylinder 1, a feeding assembly 2, and a crushing assembly 3.

[0023] As Figures 1 - 4 shown, an inner cylinder 11 is coaxially and fixedly connected inside the outer cylinder 1. The bottom end of the outer cylinder 1 is coaxially connected to a solution cylinder 12. A reaction cylinder 13 is coaxially sleeved outside the outer cylinder 1 and is used to store absolute ethanol. A filter cartridge 14 is coaxially embedded in the reaction cylinder 13. The filter cartridge 14 is in contact with the reaction cylinder 13. The filter cartridge 14 is coaxially sleeved on the inner cylinder 11. The filter cartridge 14 is in contact with the inner cylinder 11. The upper end of the reaction cylinder 13 is coaxially connected to a condensation cylinder 15. The condensation cylinder 15 is communicated with the reaction cylinder 13. A siphon 16 is communicated between the reaction cylinder 13 and the filter cartridge 14.

[0024] It should be noted that the outer cylinder 1 is arranged in an inverted U shape. The top end of the siphon tube 16 penetrates through the bottom end of the side wall of the reaction cylinder 13 and forms a communication state with the filter cylinder 14, so that the solution in the filter cylinder 14 can be sucked by the siphon tube 16 as much as possible.

[0025] As Figure 3 and Figure 4 shown, a plurality of holes for the passage of chili powder are uniformly arranged circumferentially at the top of the side wall of the inner cylinder 11. The design of the holes enables the chili powder inside the inner cylinder 11 to leave the inner cylinder 11 only from here, and the size of the chili powder that can drill out of the inner cylinder 11 is limited by the size of the holes.

[0026] It should be noted that in the specific embodiment of the present application, the solution cylinder 12 and the reaction cylinder 13 are externally connected to a heating device. First, the absolute ethanol in the solution cylinder 12 can be heated and vaporized. Secondly, the chili powder and absolute ethanol in the reaction cylinder 13 (i.e., inside the filter cylinder 14) can be heated to accelerate the dissolution of capsaicin.

[0027] As Figure 3 and Figure 4 shown, the outer cylinder 1 is inserted into the filter cylinder 14, and a feeding channel is formed between the outer cylinder 1, the inner cylinder 11 and the filter cylinder 14. That is, the chili powder drilled out of the inner cylinder 11 enters the inside of the filter cylinder 14 through the gap between the outer cylinder 1 and the inner cylinder 11.

[0028] As Figures 1 - 5 shown, the feeding assembly 2 includes a feeding cylinder 21, a feeding hopper 22 and a motor 23. The feeding cylinder 21 is coaxially and rotatably inserted into the inner cylinder 11 and extends out of the outer cylinder 1. The feeding hopper 22 is coaxially arranged at one end of the feeding cylinder 21 extending out of the outer cylinder 1 and is fixed to the outer cylinder 1. The motor 23 is fixed to the outer cylinder 1 and provides the power for the feeding cylinder 21 to rotate. It can be understood from this that the feeding cylinder 21 can be driven to rotate inside the inner cylinder 11 by the motor 23. Secondly, through the rotation of the feeding cylinder 21, it is possible to prevent the chili fed from the feeding hopper 22 from forming a blockage inside the feeding cylinder 21, and the rotation can also make the chili generate centrifugal force, ultimately facilitating the chili to leave the inside of the feeding cylinder 21 and enter the inner cylinder 11.

[0029] As Figure 3 、 Figure 4 and Figure 7 shown, the crushing assembly 3 includes a spiral conveying blade 31 and a crushing part 32. The spiral conveying blade 31 is coaxially sleeved on the feeding cylinder 21, and the crushing part 32 is fixed to the side wall of the spiral conveying blade 31 and is in clearance fit with the inner wall of the inner cylinder 11. It can be understood from this that since the spiral conveying blade 31 is designed in a spiral shape, the whole crushing part 32 is also designed in the same spiral shape, so that while the chili in the inner cylinder 11 is axially conveyed upward, it is also simultaneously crushed by the crushing part 32.

[0030] Among them, asFigure 3 , Figure 4 and Figure 6 As shown, the hole arranged on the top of the side wall of the inner cylinder 11 is a filter hole 111, and the filter hole 111 is inclined. The end of the filter hole 111 facing the inner side of the inner cylinder 11 is higher than the end of the filter hole 111 facing the outer side of the inner cylinder 11, and the top of the spiral conveying blade 31 is located within the height range of the filter hole 111 on the side wall of the inner cylinder 11. It can be seen that, firstly, the inclined setting of the filter hole 111 helps the crushed chili powder inside the inner cylinder 11 to pass through, and avoids the chili powder remaining in the filter hole 111 as much as possible. Secondly, the position of the top of the spiral conveying blade 31 is limited, so that the end point of the spiral conveying blade 31 in conveying the chili and chili powder upward is limited, which helps the chili powder to drill out of the inner cylinder 11.

[0031] like Figures 1 - 4 As shown, a plurality of steam pipes 121 are evenly connected circumferentially between the solution cylinder 12 and the condensation cylinder 15 , so as to facilitate the anhydrous ethanol vaporized by heat in the solution cylinder 12 to enter the interior of the condensation cylinder 15 .

[0032] It should be noted that a condenser tube (not shown in the figure) of an external refrigeration device is provided in the condenser cylinder 15 so that the vaporized anhydrous ethanol entering the condenser cylinder 15 can be transformed from a gaseous state to a liquid state.

[0033] In the specific embodiment of the present application, the reaction cylinder 13 and the filter cylinder 14 are both arranged in an annular shape, wherein the cross section of the filter cylinder 14 is U-shaped, such as Figure 4 As shown, the reaction cylinder 13 wraps the filter cylinder 14 .

[0034] like Figure 3 and Figure 4 As shown, a plurality of conduits 151 are evenly connected to the bottom of the condensing cylinder 15 in a circumferential direction, and the conduits 151 extend to the inner bottom of the filter cylinder 14 to facilitate the formation of liquid anhydrous ethanol to enter the filter cylinder 14. It should be noted that a one-way valve is arranged in the conduit 151, and the flow direction of the one-way valve is from the condensing cylinder 15 to the filter cylinder 14.

[0035] like Figures 1 - 5 As shown, one end of the feed barrel 21 extending out of the outer barrel 1 is coaxially sleeved with a bevel gear ring 211, and one end of the feed barrel 21 located at the bottom of the inner barrel 11 is provided with a notch 212. It can be understood that when the feed barrel 21 rotates, the peppers therein will be thrown into the inner barrel 11 from the notch 212 under the action of centrifugal force, and the feed barrel 21 and the notch 212 thereon during the rotation process will allow the peppers to be evenly thrown into the inner barrel 11.

[0036] Among them, a plurality of support rods 221 are evenly fixed to the circumference of the feeding hopper 22 , and the plurality of support rods 221 are fixed to the outer cylinder 1 , so as to facilitate the fixing of the feeding hopper 22 .

[0037] likeFigure 4 and Figure 5 As shown, the output end of the motor 23 is key-connected with a bevel gear 231, and the bevel gear 231 meshes with the bevel gear ring 211. Thus, it can be understood that the motor 23 can drive the feeding cylinder 21 to rotate.

[0038] As Figure 7 shown, grooves 311 are provided on the side wall of the spiral conveyor blade 31. The crushing member 32 includes a fixing strip 321 embedded in the groove 311 and a plurality of crushing teeth 322 uniformly fixed to the fixing strip 321. The plurality of crushing teeth 322 are arranged at intervals. Thus, it can be understood that the rotation of the feeding cylinder 21 will synchronously drive the spiral conveyor 31 and the crushing member 32 on its side wall to rotate, achieving the effect of axially transporting and crushing the chili peppers at the same time.

[0039] On the other hand, the present application further provides a method for rough extraction of capsaicin, including the following steps: S1, Chili pepper crushing: Put the chili peppers into the feeding hopper 22, enter the inner cylinder 11 through the feeding cylinder 21, start the motor 23 to rotate the feeding cylinder 21, and use the centrifugal force generated by the rotation to throw the chili peppers from the notch 212 at the bottom end of the feeding cylinder 21 into the inner cylinder 11. At the same time, the spiral conveyor blade 31 rotates driven by the feeding cylinder 21, and conveys the chili peppers at the bottom of the inner cylinder 11 upward. During the conveying process, the crushing member 32 is used to complete the crushing operation on the chili peppers; S2, Conveying chili pepper powder: The chili peppers are axially conveyed by the spiral conveyor blade 31 to the hole (i.e., the filter hole 111) at the top end of the inner cylinder 11 for the chili pepper powder to pass through. The chili pepper powder smaller than the inner diameter of the filter hole 111 after crushing can pass through the filter hole 111 and enter the channel between the outer cylinder 1 and the side wall of the inner cylinder 11. The larger powder still remains in the inner cylinder 11 and continues to be crushed by the crushing member 32 until it meets the standard. The chili pepper powder that enters the channel between the outer cylinder 1 and the inner cylinder 11 drops to the bottom end of the filter cylinder 14; S3, Conveying anhydrous ethanol: Use the heating device externally connected to the solution cylinder 12 to vaporize the anhydrous ethanol therein, and enter the condensate cylinder 15 through the steam pipe 121 to form condensate. The condensate drips onto the chili pepper powder in the filter cylinder 14 through the conduit 151 to dissolve the capsaicin in the chili pepper powder. The chili pepper crushing treatment can improve the full dissolution between the capsaicin in it and the anhydrous ethanol, and improve the dissolution efficiency of capsaicin; S4, Solution reflux: As more and more anhydrous ethanol condenses in the filter cylinder 14, when the liquid level height exceeds the siphon tube 16, the siphon tube 16 will generate a siphon effect to suck the anhydrous ethanol dissolved with capsaicin in the filter cylinder 14 back into the solution cylinder 12. And the solution cylinder 12 is continuously heated, and the anhydrous ethanol therein is continuously vaporized and conveyed into the condensate cylinder 15, that is, step S3 is repeated. In this way, multiple times of solution reflux are formed, which can fully dissolve the capsaicin in the chili pepper powder and improve the extraction effect of capsaicin; S5. Separate capsaicin. Collect the solution after multiple refluxes in the solution cylinder 12. Evaporate absolute ethanol under reduced pressure at low temperature to separate capsaicin from absolute ethanol, thus completing the crude extraction of capsaicin.

[0040] In the related art, for this crude capsaicin extraction device and method, although the absolute ethanol dissolved with capsaicin in the filter cylinder 14 can be sucked back into the solution cylinder 12 through the siphon effect, and the solution in the solution cylinder 12 is continuously heated to continuously vaporize the absolute ethanol in it and then liquefy again after entering the condensation cylinder 15 and enter the filter cylinder 14 again to dissolve capsaicin again. However, the siphon effect is affected by various factors such as pressure, liquid level height, and the height and thickness of the siphon tube 16. Once the siphon effect cannot be completed, it will affect the normal extraction of capsaicin. Secondly, even if the siphon effect can be continuously completed, each time the solution is sucked back from the direction of the filter cylinder 14 is not thorough, and there will always be residual solution in the pepper powder in the filter cylinder 14. Especially when the last siphon is completed during multiple siphons, the residual solution in the pepper powder cannot be completely extracted, resulting in the residual of absolute ethanol dissolved with capsaicin in the pepper powder, causing certain resource waste.

[0041] Example two. According to some embodiments of the present application, as Figures 8 - 13 shown, an auxiliary mechanism 4 is provided inside the outer cylinder 1 and the reaction cylinder 13.

[0042] Specifically, the auxiliary mechanism 4 includes a transmission component 41, a lifting component 42, a pressing plate 43, a plurality of pressure sensors 44, and a plurality of passive baffles 45. Among them, the transmission component 41 drives the filter cylinder 14 to rotate by the rotation of the feeding cylinder 21. It can be understood that when the filter cylinder 14 rotates, the conduit 151 inside it remains stationary. Thus, the pepper powder and absolute ethanol in the filter cylinder 14 will first form a mixture under the action of centrifugal force, and secondly, the conduit 151 will stir the pepper powder and absolute ethanol, further promoting the full dissolution of capsaicin in the pepper powder by absolute ethanol, and improving the extraction efficiency and effect of capsaicin.

[0043] The lifting component 42 is uniformly fixed to the outer side of the reaction cylinder 13.

[0044] The pressing plate 43 is coaxially and slidably arranged inside the filter cylinder 14. The pressing plate 43 is slidably sleeved on the liquid discharge end of the condensation cylinder 15 (i.e., the conduit 151). It can be understood that when the filter cylinder 14 rotates, the pressing plate 43 remains stationary under the action of the conduit 151.

[0045] A plurality of pressure sensors 44 are uniformly fixed to the inner top end of the filter cylinder 14 to facilitate assisting in determining the water level height and cooperating with other related components to forcibly form a siphon effect.

[0046] A plurality of passive baffles 45 are circumferentially and uniformly arranged at the bottom end of the side wall of the outer cylinder 1, and a radial sealing and sliding fit is formed between the passive baffle 45 and the filter cartridge 14.

[0047] Specifically, as Figure 9 shown, the transmission assembly 41 includes a sealing plate 411, a transmission gear ring 412, a plurality of passive gears 413, a plurality of positioning shafts 414, a plurality of transmission shafts 415 and a plurality of transmission gears 416. The sealing plate 411 is coaxially and sealingly rotatably connected to the top end of the inner cylinder 11, and the sealing plate 411 is fixedly sleeved on the feeding cylinder 21. It can be seen therefrom that when the feeding cylinder 21 rotates, it will drive the sealing plate 411 to rotate synchronously and in the same direction, and the sealing plate 411 covers the open top of the inner cylinder 11, preventing the peppers in the inner cylinder 11 from jumping out of the top of the inner cylinder 11 and falling into the filter cartridge 14, which affects the normal extraction efficiency and effect of capsaicin; The transmission gear ring 412 is coaxially fixed to the sealing plate 411 and extends out of the side wall of the sealing plate 411; a plurality of passive gears 413 are circumferentially and uniformly distributed on the periphery of the transmission gear ring 412, and the plurality of passive gears 413 are engaged with the transmission gear ring 412; a plurality of positioning shafts 414 are respectively fixedly connected to the plurality of passive gears 413 one by one, and the positioning shafts 414 are rotatably connected to the inner top of the outer cylinder 1. It can be seen therefrom that when the transmission gear ring 412 follows the sealing plate 411 to rotate, it will drive the plurality of passive gears 413 on the periphery to rotate synchronously; A plurality of transmission shafts 415 are respectively fixedly connected to the plurality of passive gears 413 one by one, and the transmission shafts 415 extend into the interior of the filter cartridge 14; a plurality of transmission gears 416 are respectively fixedly connected to the plurality of transmission shafts 415 one by one.

[0048] Specifically, as Figure 11 shown, a passive gear ring 141 is coaxially fixed to the inner wall of the filter cartridge 14, an inclined surface 142 is provided at the top end of the passive gear ring 141, and the plurality of transmission gears 416 are respectively engaged with the passive gear ring 141. It can be seen therefrom that the transmission gears 416 will drive the passive gear ring 141 to rotate under the action of the passive gears 413, and then drive the filter cartridge 14 to rotate.

[0049] Furthermore, a support ring 131 is coaxially fixed to the outer wall of the reaction cylinder 13. The lifting assembly 42 includes at least two hydraulic cylinders 421, a plurality of lifting rods 422 and a plurality of connecting pieces 423. At least two hydraulic cylinders 421 are circumferentially and uniformly fixed to the support ring 131; a plurality of lifting rods 422 slidably penetrate through the reaction cylinder 13 and extend into the filter cartridge 14 to abut against the pressing plate 43; a plurality of connecting pieces 423 respectively fix the piston ends of the hydraulic cylinders 421 and the lifting rods 422. It can be seen therefrom that when the piston ends of the hydraulic cylinders 421 descend, they will synchronously drive the pressing plate 43 to descend in the filter cartridge 14.

[0050] It should be noted that in the initial state, the piston end of the hydraulic cylinder 421 extends to the limit position and does not apply a downward pressing force on the pressing plate 43.

[0051] As Figure 12 and Figure 13 shown, a plurality of cross plates 143 and a plurality of vertical plates 144 are annularly arrayed inside the filter cartridge 14. The plurality of cross plates 143 and the plurality of vertical plates 144 are fixedly connected, and adjacent cross plates 143 and vertical plates 144 do not contact each other. Limiting grooves 145 are symmetrically arranged on both sides of the vertical plate 144.

[0052] It should be noted that in the specific embodiment of the present application, the bottom end of the outer cylinder 1 abuts against the cross plate 143, and the diameter of the outer cylinder 1 is the same as the diameter of the ring formed by the plurality of vertical plates 144.

[0053] Furthermore, a plurality of passive baffles 45 are respectively radially sealed and slid between adjacent cross plates 143 and vertical plates 144. It should be noted that there is a sealed sliding connection between the passive baffle 45 and the bottom end of the outer cylinder 1.

[0054] Two limiting blocks 451 are symmetrically and fixedly connected to both sides of the passive baffle 45. The limiting blocks 451 are limited and slid in the limiting grooves 145. It can be understood that the on-off of the feeding channel between the inner cylinder 11 and the filter cartridge 14 is realized by the radial sealed sliding of the passive baffle 45 between adjacent cross plates 143 and vertical plates 144. Specifically, when the passive baffle 45 is displaced radially outward, at this time, the passive baffle 45 disengages from the two adjacent vertical plates 144, the two cross plates 143 and the bottom end of the outer cylinder 1. At this time, an open channel is formed by the two vertical plates 144, the two cross plates 143 and the bottom end of the outer cylinder 1. On the contrary, when the passive baffle 45 is displaced radially inward, the passive baffle 45 will form a closed state for this channel.

[0055] Therefore, during specific use, when the liquid level in the filter cartridge 14 does not exceed the height of the siphon tube 16, under the rotation of the filter cartridge 14, the passive baffle 45 will move radially outward due to centrifugal force. Thus, an open channel is formed by the two vertical plates 144, the two horizontal plates 143, and the bottom end of the outer cylinder 1. It can be understood that in this state, the chili powder drilled out at the filter holes 111 on the inner cylinder 11 can continuously fall into the filter cartridge 14, and the rotation of the filter cartridge 14 will cause the conduit 151 inside it to agitate the objects inside the filter cartridge 14. In this way, a sufficient mixture can be formed between the chili powder and the absolute ethanol in the filter cartridge 14, improving the dissolution effect and efficiency of the absolute ethanol on capsaicin. As the absolute ethanol continuously enters the inside of the filter cartridge 14, the liquid level in the filter cartridge 14 rises accordingly, and simultaneously causes the pressing plate 43 to rise. It rises until the pressing plate 43 touches the pressure sensor 44 (it should be noted here that the water level at this time is not lower than the height of the siphon tube 16 to prevent the mixed solution in the filter cartridge 14 from not being able to enter the solution cylinder 12 when the siphon effect cannot be completed), and then the hydraulic cylinder 421 is started, and its piston end retracts, that is, drives the lifting rod 422 to move downward, forcing the pressing plate 43 to move downward, squeezing the chili powder and the mixed solution below it. Due to the extrusion of the chili powder and the mixed liquid, it will force the passive baffle 45 to move radially inward until the originally unobstructed channel (the open channel formed by the two vertical plates 144, the two horizontal plates 143, and the bottom end of the outer cylinder 1) is closed. At this time, the piston end of the hydraulic cylinder 421 continues to descend. In this way, the pressure in the space where the chili powder and the mixed liquid are located will increase, and then force the siphon tube 16 to be in an unobstructed state, so that the mixed liquid enters the solution cylinder 12 through the siphon tube 16, forcing the siphon tube 16 to complete a siphon action. During this process, because a one-way valve is provided in the conduit 151, it can prevent the mixed solution or chili powder from entering the conduit 151, and the design of the filter cartridge 14 can prevent chili powder from entering the siphon tube 16.

[0056] Of course, in the specific embodiment of the present application, the piston end of the hydraulic cylinder 421 resets actively after descending. The specific circuit design and program design can be realized in the related prior art, and will not be elaborated here.

[0057] With this design, through the design of the pressing plate 43, the pressure sensor 44, and the passive baffle 45, it can be ensured that when the siphon tube 16 in the crude extraction device of the present application cannot complete the siphon action independently, a passive solution reflux effect will also be formed, and the extrusion of the pressing plate 43 further promotes the separation between the mixed solution and the chili powder, effectively saving resources and improving the extraction effect of capsaicin.

[0058] In the related art, for a crude capsaicin extraction device and a crude extraction method thereof, since the chili peppers need to be crushed and then the capsaicin therein is dissolved with absolute ethanol, the crushed chili peppers are relatively light in weight. Therefore, when being conveyed into the filter cylinder 14, although the filter holes 111 are inclined, it is still impossible to ensure that the filter holes 111 are not blocked. Once the filter holes 111 are blocked, the extraction efficiency of capsaicin in the filter cylinder 14 will be affected.

[0059] Embodiment 3. According to some embodiments of the present application, as Figure 3 、 Figures 14 - 16 shown, a knocking mechanism 5 is provided at the bottom end of the sealing plate 411. The knocking mechanism 5 is located inside the inner cylinder 11. The knocking mechanism 5 includes a plurality of arc-shaped blocks 51 and a plurality of knocking components 52. The plurality of arc-shaped blocks 51 are circumferentially and fixedly connected to the inner cylinder 11. The plurality of arc-shaped blocks 51 are located on the top side of the holes provided in the side wall of the inner cylinder 11. It can be understood that the arc-shaped blocks 51 are prevented from hindering the chili powder.

[0060] As Figure 14 shown, the plurality of knocking components 52 are distributed in a fan shape. The plurality of knocking components 52 are located at the rear side of the rotation direction of the top end of the spiral conveying blade 31. It can be understood that the knocking components 52 are prevented from affecting the normal conveying action of the spiral conveying blade 31. The plurality of knocking components 52 are respectively arranged at intervals with the corresponding plurality of arc-shaped blocks 51 within the corresponding range.

[0061] Specifically, the knocking component 52 includes a fixed block 521, a guide rod 522, a spring 523, a slider 524, a connecting rod 525 and a disc 526. The fixed block 521 is fixedly connected to the sealing plate 411 along the radial direction. A cavity is provided inside the fixed block 521; the guide rod 522 is fixedly connected to the cavity inside the fixed block 521 along the length direction; the spring 523 is sleeved on the guide rod 522; the slider 524 slides in the cavity inside the fixed block 521, and the slider 524 is slidably sleeved on the guide rod 522; one end of the connecting rod 525 is fixedly connected to the slider 524, and the other end of the connecting rod 525 extends out of the fixed block 521. The connecting rod 525 is slidably adapted to the fixed block 521, and the connecting rod 525 is slidably adapted to the arc-shaped block 51; the disc 526 is fixedly connected to the end of the connecting rod 525 extending out of the fixed block 521, and the disc 526 is intermittently abutted against the side wall of the inner cylinder 11.

[0062] Therefore, during specific use, since the sealing plate 411 rotates with the feeding cylinder 21, it will drive the plurality of knocking components 52 distributed in a fan shape to rotate synchronously. The plurality of arc-shaped blocks 51 are arranged at intervals. In this way, a sliding contact phenomenon will occur between the connecting rod 525 and the plurality of arc-shaped blocks 51. It should be noted that in the initial state, under the elastic force of the spring 523, the slider 524 is located at one end of the fixed block 521 facing the inner wall of the inner cylinder 11, that is, at this time, the disc 526 abuts against the inner wall of the inner cylinder 11. At this time, the connecting rod 525 is located between two adjacent arc-shaped blocks 51 and does not contact the arc-shaped blocks 51. When the knocking component 52 rotates with the sealing plate 411, the connecting rod 525 gradually rotates towards one of the arc-shaped blocks 51. As the rotation continues, it will form a sliding contact with the arc-shaped block 51. Under the protrusion of the arc-shaped block 51, the connecting rod 525 will be radially squeezed inward, that is, during this process, the slider 524 will move radially inward along the guide rod 522 and squeeze the spring 523. At this time, the disc 526 separates from the inner wall of the inner cylinder 11. As the rotation continues, when the connecting rod 525 rotates to the other side of the arc-shaped block 51, under the elastic force of the spring 523, it will move radially outward. In this way, the disc 526 approaches the inner wall of the inner cylinder 11 again. It can be understood that during the continuous rotation process, the plurality of discs 526 in the plurality of knocking components 52 will form a continuous knocking action on the inner wall of the inner cylinder 11. In this way, the vibration will occur at the filter holes 111 on the inner cylinder 11, and the chili powder stuck inside will fall off as much as possible, that is, to a certain extent, the phenomenon of blockage at the filter holes 111 is prevented, and the normal conveying effect of the chili powder is improved.

[0063] It should be noted that the specific model specifications of the siphon 16, the passive gear ring 141, the motor 23, the bevel gear ring 211, the bevel gear 231, the spiral conveyor blade 31, the pressure sensor 44, the transmission gear ring 412, the passive gear 413, the transmission gear 416, the hydraulic cylinder 421 and the spring 523 need to be selected according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0064] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
