Description

Technical Field

[0001] This invention belongs to the field of Yunnan olive extraction and processing technology, specifically relating to a Yunnan olive tannin extraction device. Background Technology

[0002] Yunnan olive, also known as Yunnan amla, is the fruit of *Eupatorium fortunei*, a deciduous shrub or tree belonging to the Euphorbiaceae family. The plant flowers in spring, with small, solitary, yellow flowers; it is monoecious. The fruit is fleshy, oblate, and turns red when ripe. Yunnan olive is an important plant resource used for both medicinal and edible purposes. Its juice has a unique flavor and is rich in nutrients. Besides containing amino acids and trace elements, it is particularly high in Vitamin C. Due to the protection of flavonoids and tannins, Yunnan olive retains up to 72% of its Vitamin C even after processing, far exceeding that of other fruits and vegetables. The fruit is used medicinally, possessing the effects of clearing heat and relieving sore throat, moistening the lungs and resolving phlegm, and promoting the production of body fluids and quenching thirst.

[0003] Modern research shows that Yunnan olives are rich in tannins. Tannic acid has strong antioxidant capacity and good pharmacological activity, and is widely used in health products, pharmaceuticals, and cosmetics. Extracting tannins from Yunnan olives is a new approach to tannin extraction in recent years. The process of extracting tannins from Yunnan olives generally includes raw material selection, soaking and washing, crushing and pulping, soaking and extraction, filtration and separation, and concentration. The cleanliness of Yunnan olives directly affects the processing quality of the product. Therefore, the selected fresh Yunnan olives need to be washed multiple times before extraction. Currently, Yunnan olives are generally washed using drum-type or agitator-type washing machines, or manually. When using the above mechanical washing, collisions between the fruit and the machinery or rapid collisions between the fruits can easily occur, leading to premature fruit breakage and loss of some extractable substances. While manual washing can avoid this situation, it consumes a lot of manpower and resources, which is not conducive to reducing production and processing costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a Yunnan olive tannin extraction device.

[0005] The technical solution adopted to solve the above technical problems is: a Yunnan olive tannin extraction device, including a washing tank, the washing tank including a tank body, a bottom partition plate fixedly connected to the center of the bottom inner surface of the tank body, and a support plate fixedly connected to one side of the front and rear ends of the inner wall of the tank body.

[0006] A rolling cleaning mechanism is provided on one side of the center of the pool. The rolling cleaning mechanism includes a first drive roller and a first driven roller rotatably connected between the front and rear ends of the inner wall of the pool. A first conveyor belt is installed between the first drive roller and the first driven roller. The first conveyor belt has multiple evenly distributed positioning circular holes and strip-shaped sewage discharge holes. A first drive motor connected to the first drive roller is installed at the front end of the pool. A central cleaning plate is installed at the center of the first conveyor belt. A top fixing plate is fixedly installed at the top between the two support plates. The bottom end of the top fixing plate has an arc-shaped structure. This design allows the Yunnan olives in the positioning holes to more easily enter between the top cleaning sponge and the middle cleaning plate. The bottom of the top fixing plate is equipped with a top cleaning sponge. A first guide plate is fixedly installed at the bottom position on one side of the inner wall of the pool. A second guide plate is fixedly connected to the top of the outer wall of the bottom partition on the side away from the first guide plate. During processing, an appropriate amount of clean water is first injected into the pool, and the first drive motor is started. Then, the soaked Yunnan olives are poured into the pool. The first drive motor drives the first drive roller and the first conveyor belt to rotate in a specific direction via its output shaft. Because the first conveyor belt has multiple evenly spaced... Distributed positioning holes allow some Yunnan olives on the first conveyor belt to roll into their corresponding holes. The diameter of these holes is larger than the average diameter of the Yunnan olives. Olives falling into these holes move synchronously with the first conveyor belt. A central cleaning plate is installed at the center of the first conveyor belt. The central cleaning plate is made of rigid material, with sponge on both the top and bottom surfaces. A top cleaning sponge is located at the bottom of the top fixing plate. There are gaps between the central cleaning plate, the top cleaning sponge, and the first conveyor belt, and these gaps are smaller than the average diameter of the Yunnan olives. Therefore, when the Yunnan olives move with the first conveyor belt... During this process, due to friction, the Yunnan olives will roll freely in the corresponding positioning holes, thus continuously rolling and rubbing against the middle cleaning plate and the top cleaning sponge, thereby achieving automatic cleaning of the Yunnan olives and removing some debris attached to the surface of the Yunnan olives; the first conveyor belt also has multiple evenly distributed strip-shaped sewage discharge holes, so that some pollutants attached to the first conveyor belt can fall into the bottom of the pool through the strip-shaped sewage discharge holes, and finally be discharged through the first sewage outlet with the water flow. When the Yunnan olives move to the top position of the first conveyor belt, they will fall naturally and fall onto the lifting conveyor mechanism through the second guide plate;

[0007] A debris collection mechanism is provided on the outer wall of the pool near the rolling cleaning mechanism, a lifting and conveying mechanism is provided on the center of the pool away from the rolling cleaning mechanism, and a high-pressure spraying mechanism corresponding to the lifting and conveying mechanism is installed on one side of the top of the pool.

[0008] The washing tank is provided with a crushing and pulping mechanism, a heating and extraction mechanism, a filtration and separation mechanism, and a depressurization and concentration mechanism in sequence on the side away from the debris collection mechanism.

[0009] The crushing and pulping mechanism, heating and extraction mechanism, filtration and separation mechanism, and vacuum concentration mechanism are connected by a pumping mechanism.

[0010] Furthermore, a water inlet is provided on one side of the rear end of the inner wall of the pool, and a waste outlet is provided at the center of one side of the inner wall of the pool. The front and rear ends of the inner wall of the pool are respectively provided with positioning grooves and positioning holes for supporting and positioning the middle cleaning plate, and a detachable cover plate for sealing the middle cleaning plate is installed at the rear center of the positioning hole. A first sewage outlet and a second sewage outlet are respectively provided on both sides of the bottom front end of the pool.

[0011] With the above technical solution, during processing, water can be slowly injected into the pool through the water inlet. When there are floating debris in the pool, the debris will flow out through the debris outlet. The sewage at the bottom of the pool can be discharged by opening the corresponding first and second sewage outlets. After the equipment is used, the detachable cover can be opened and the middle cleaning plate can be removed from the pool for cleaning.

[0012] Furthermore, the debris collection mechanism includes a debris collection box disposed on one side of the outer wall of the pool. A debris filter plate is installed at the top center of the debris collection box, and the top of the debris filter plate is flush with the bottom of the debris discharge port. A third sewage discharge port is disposed at the center of the bottom front end of the debris collection box. When floating debris follows the water flow into the debris collection box through the sewage discharge port, the floating debris will be intercepted by the debris filter plate, while the water flow will enter the debris collection box and then be discharged outward through the third sewage discharge port.

[0013] Furthermore, the lifting and conveying mechanism includes a second drive roller shaft and a second driven roller shaft rotatably connected between the front and rear ends of the inner wall of the pool. A second conveyor belt is installed between the second drive roller shaft and the second driven roller shaft. The outer surface of the second conveyor belt is provided with a plurality of evenly distributed limiting strips. Each of the plurality of limiting strips is provided with a strip-shaped drainage hole. A second drive motor connected to the second drive roller shaft is installed on the outer surface of the front end of the pool. A guide frame corresponding to the second conveyor belt is fixedly installed on the top of the outer wall of the pool on the side away from the debris collection mechanism.

[0014] With the above technical solution, when the Yunnan olives after the rolling cleaning are dropped onto the second conveyor belt via the second guide plate, the second conveyor belt will move in a direction under the drive of the second drive motor. The second conveyor belt is equipped with multiple limit strips, which will drive the Yunnan olives to continue moving towards the top of the other end of the pool. In addition, each of the multiple limit strips is provided with a strip-shaped drainage hole, so that the water sprayed by the subsequent high-pressure spraying mechanism can flow to the bottom of the pool through the strip-shaped drainage hole, thereby realizing the rapid drainage of the cleaned Yunnan olives and preventing a large amount of cleaning water from being sent into the crushing and pulping mechanism along with the Yunnan olives.

[0015] Furthermore, the high-pressure spraying mechanism includes a fixed frame fixed to one side of the top of the pool body. A guide pipe is installed between the front and rear ends of the inner wall of the fixed frame. Multiple evenly distributed high-pressure nozzles are installed at the bottom end of the guide pipe. A water supply connector communicating with the guide pipe is provided at the rear end of the fixed frame.

[0016] With the above technical solution, when the water supply connector is connected to the high-pressure water flow, the water flow will enter the guide pipe through the water supply connector, and then be sprayed downward through multiple high-pressure nozzles, thereby realizing secondary high-pressure cleaning of the Yunnan olives on the second conveyor belt, so that the Yunnan olives can be cleaned more thoroughly.

[0017] Furthermore, the crushing and pulping mechanism includes a crushing cylinder located at the bottom of the guide frame. The bottom of the crushing cylinder is arranged in an inverted cone shape. A fixed top cover is fixedly installed on the top of the crushing cylinder. A crushing motor is installed at the center of the top of the fixed top cover. A rotating shaft is fixedly connected to the bottom end of the output shaft of the crushing motor. Multiple sets of evenly distributed crushing blades are fixedly installed on the outer wall of the rotating shaft. A feeding hole is opened on one side of the top of the fixed top cover. A sliding cover is slidably connected between the front and rear ends of the inner wall of the feeding hole. A top protective frame is fixedly connected to the top side of the feeding hole. A first solenoid valve is installed at the center of the discharge port at the bottom of the crushing cylinder, and a first discharge pipe is fixedly installed at the center of the bottom of the crushing cylinder.

[0018] With the above technical solution, when the Yunnan olives move to the top position with the second conveyor belt, they will fall naturally and then roll into the crushing cylinder through the guide frame. After all the material is fed, the sliding cover is slid to close the feeding hole. At this time, the crushing motor is started. The output shaft of the crushing motor will drive the rotating shaft and multiple sets of evenly distributed crushing blades to quickly crush the Yunnan olives in the crushing cylinder to form slurry. When the first solenoid valve is opened, the first pump body can pump the slurry to the heating and extraction mechanism through the first discharge pipe and the first feeding pipe.

[0019] Furthermore, the heating extraction mechanism includes a heating extraction tank disposed on one side of the crushing and pulping mechanism. Multiple first support legs are fixedly connected to the bottom edge of the heating extraction tank. A first tank cover is installed on the top of the heating extraction tank. A first water inlet is provided on one side of the top of the first tank cover. An electromagnetic heating coil is installed at the center of the inner wall of the heating extraction tank. A second solenoid valve is installed at the center of the bottom outlet of the heating extraction tank. A second discharge pipe is installed at the bottom end of the second solenoid valve.

[0020] With the above technical solution, after the slurry is introduced into the heating extraction tank, an appropriate amount of extraction solvent is added to the heating extraction tank through the first water inlet. The tank is soaked for about one hour, and then the heating extraction tank is heated to 75-80°C by the electromagnetic heating coil. The heating is stopped after 20 minutes. Then the second solenoid valve is opened, and the second pump body can pump the slurry to the filtration and separation mechanism through the second discharge pipe and the second feeding pipe.

[0021] Furthermore, the filtration and separation mechanism includes a filtration and separation box located on the other side of the heating extraction tank. A bottom support frame is fixedly connected to the bottom of the filtration and separation box, and a support frame is fixedly connected to the bottom of the inner wall of the filtration and separation box. A separable activated carbon filter box is installed at the center of the support frame. A protective door is rotatably connected to the front opening of the filtration and separation box. A third solenoid valve is installed at the center of the bottom outlet of the filtration and separation box, and a third discharge pipe is installed at the bottom end of the third solenoid valve.

[0022] With the above technical solution, after the slurry is introduced into the filtration and separation box, the slurry also accumulates on the top of the activated carbon filter box. The activated carbon filter box is equipped with activated carbon packs. After the liquid in the slurry is filtered by the activated carbon, it enters the bottom of the filtration and separation box to form an extract. At this time, the third solenoid valve is opened, and the third pump body can pump the extract to the pressure reduction and concentration mechanism through the third discharge pipe and the third feeding pipe.

[0023] Furthermore, the pressure reduction and concentration mechanism includes a concentration tank disposed on one side of the filter separation box. Multiple second support legs are fixedly connected to the bottom edge of the concentration tank. A second tank cover is fixedly installed on the top of the concentration tank. A second water inlet is provided on one side of the top of the second tank cover. A fourth solenoid valve is installed at the center of the discharge port at the bottom of the concentration tank. A fourth discharge pipe is installed at the bottom end of the fourth solenoid valve.

[0024] With the above technical solution, after the extract enters the concentration tank, the extract can be concentrated under reduced pressure. Finally, the fourth solenoid valve is opened, and the viscous liquid after reduced pressure concentration will flow out through the fourth discharge pipe. The liquid is collected and then dried to obtain a high-purity tannin product.

[0025] Furthermore, the pumping mechanism includes a first pump body, a second pump body, and a third pump body. One end of the first discharge pipe is connected to the inlet of the first pump body, and the outlet of the first pump body is connected to a first feeding pipe that communicates with the first tank cover. One end of the second discharge pipe is connected to the inlet of the second pump body, and the outlet of the second pump body is connected to a second feeding pipe that communicates with the top of the filter separation box. One end of the third discharge pipe is connected to the inlet of the third pump body, and the outlet of the third pump body is connected to a third feeding pipe that communicates with the top of the second tank cover.

[0026] Through the above technical solution, the first pump body, the second pump body and the third pump body are mainly used to pump the slurry during the extraction process to realize automated production line processing.

[0027] The beneficial effects of the present invention are as follows: (1) By designing a rolling cleaning mechanism, when Yunnan olives move with the conveyor belt, they will roll freely in the corresponding positioning holes, thereby continuously rolling and rubbing against the middle cleaning plate and the top cleaning sponge, thus realizing automatic cleaning of Yunnan olives, thereby removing some impurities attached to the surface of Yunnan olives, ensuring cleaning efficiency, and also avoiding fruit breakage; (2) By adopting a rolling friction automatic cleaning structure, the present invention can effectively avoid collisions between fruits and mechanical equipment or rapid collisions between fruits, thereby preventing premature breakage of fruits and avoiding loss of extracted substances; (3) By designing a fully automated production line, the present invention can fully automatically complete the fully automated extraction and processing of tannins in Yunnan olives, which not only greatly improves production efficiency, but also saves a lot of labor costs.

[0046] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0047] like Figures 1-6As shown, this embodiment of the Yunnan olive tannin extraction equipment includes a washing tank 1, which includes a tank body 101. A bottom partition 102 is fixedly connected to the center of the bottom inner surface of the tank body 101. Support plates 106 are fixedly connected to one side of the front and rear ends of the inner wall of the tank body 101. A water inlet 103 is opened on one side of the rear end of the inner wall of the tank body 101, and a waste discharge port 104 is opened at the center of one side of the inner wall of the tank body 101. Positioning grooves and positioning holes for supporting and positioning the middle washing plate 207 are respectively opened at the front and rear ends of the inner wall of the tank body 101, and a sealing device for the middle washing plate 207 is installed at the center of the rear end of the positioning hole. The detachable cover plate 105 of 07 and the first drain port 107 and the second drain port 108 are respectively provided on both sides of the bottom front end of the pool body 101. During processing, water can be slowly injected into the pool body 101 through the water inlet 103. When there are debris floating in the pool body 101, the debris will flow out through the debris outlet 104. The sewage at the bottom of the pool body 101 can be discharged by opening the corresponding first drain port 107 and the second drain port 108. After the equipment is used, the detachable cover plate 105 can be opened and the middle cleaning plate 207 can be removed from the pool body 101 for cleaning.

[0048] like Figures 6-9As shown, a rolling cleaning mechanism 2 is provided on one side of the center of the pool body 101. The rolling cleaning mechanism 2 includes a first drive roller shaft 201 and a first driven roller shaft 202 rotatably connected between the front and rear ends of the inner wall of the pool body 101. A first conveyor belt 203 is installed between the first drive roller shaft 201 and the first driven roller shaft 202. The first conveyor belt 203 has multiple evenly distributed positioning circular holes 204 and strip-shaped sewage discharge holes 205. A first drive motor 206 connected to the first drive roller shaft 201 is installed at the front end of the pool body 101. A middle cleaning plate 207 is installed at the center of the first conveyor belt 203. A top fixing plate 208 is fixedly installed at the top between the two support plates 106. The bottom end of the top fixing plate 208 is arc-shaped. The structure allows the Yunnan olives in the positioning hole 204 to more easily enter between the top cleaning sponge 209 and the middle cleaning plate 207. The bottom of the top fixing plate 208 is provided with the top cleaning sponge 209. A first guide plate 210 is fixedly installed at the bottom position on one side of the inner wall of the pool body 101. A second guide plate 211 is fixedly connected to the top of the outer wall of the bottom partition 102 on the side away from the first guide plate 210. During processing, an appropriate amount of clean water is first injected into the pool body 101, and the first drive motor 206 is started. Then, the soaked Yunnan olives are poured into the pool body 101. The first drive motor 206 will drive the first drive roller shaft 201 and the first conveyor belt 203 to rotate in a directional manner through its output shaft. Since the first conveyor belt 203 has openings Multiple evenly distributed positioning holes 204 allow some Yunnan olives located on the first conveyor belt 203 to roll into the corresponding positioning holes 204. The diameter of the positioning holes 204 is larger than the average diameter of the Yunnan olives. The Yunnan olives falling into the positioning holes 204 will move synchronously with the first conveyor belt 203. Since a central cleaning plate 207 is installed at the center of the first conveyor belt 203, the central cleaning plate 207 is made of hard material, and the upper and lower surfaces are made of sponge. A top cleaning sponge 209 is provided at the bottom of the top fixing plate 208. There are certain gaps between the central cleaning plate 207, the top cleaning sponge 209 and the first conveyor belt 203, and these gaps are smaller than the average diameter of the Yunnan olives. Therefore, when the Yunnan olives follow the first conveyor belt 203... When the conveyor belt 203 moves, due to friction, the olives will roll freely in the corresponding positioning holes 204, thus continuously rolling and rubbing against the middle cleaning plate 207 and the top cleaning sponge 209, thereby achieving automatic cleaning of the olives and removing some debris attached to the surface of the olives; the first conveyor belt 203 is also provided with multiple evenly distributed strip-shaped drain holes 205, so that some pollutants attached to the first conveyor belt 203 can fall into the bottom of the pool 101 through the strip-shaped drain holes 205, and finally be discharged through the first drain outlet 107 with the water flow. When the olives move to the top position of the first conveyor belt 203, they will fall naturally and fall onto the lifting conveyor mechanism 4 through the second guide plate 211.

[0049] like Figures 4-6 As shown, a debris collection mechanism 3 is provided on the side of the outer wall of the pool body 101 near the rolling cleaning mechanism 2. The debris collection mechanism 3 includes a debris collection box 301 located on one side of the outer wall of the pool body 101. A debris filter plate 302 is installed on the top center of the debris collection box 301, and the top of the debris filter plate 302 is flush with the bottom of the debris discharge port 104. A third sewage discharge port 303 is provided at the center of the bottom front end of the debris collection box 301. When floating debris follows the water flow into the debris collection box 301 through the debris discharge port 104, the floating debris will be intercepted by the debris filter plate 302, while the water flow will enter the debris collection box 301 and then be discharged outward through the third sewage discharge port 303.

[0050] A lifting and conveying mechanism 4 is provided on the side of the pool body 101 away from the rolling cleaning mechanism 2. The lifting and conveying mechanism 4 includes a second drive roller shaft 401 and a second driven roller shaft 402 rotatably connected between the front and rear ends of the inner wall of the pool body 101. A second conveyor belt 403 is installed between the second drive roller shaft 401 and the second driven roller shaft 402. A plurality of evenly distributed limiting strips 404 are provided on the outer surface of the second conveyor belt 403. Each of the multiple limiting strips 404 has a strip-shaped drainage hole 405. A second drive motor 406 connected to the second drive roller shaft 401 is installed on the outer surface of the front end of the pool body 101. A guide corresponding to the second conveyor belt 403 is fixedly installed on the top of the outer wall of the pool body 101 on the side away from the debris collection mechanism 3. When the Yunnan olives, after being washed by rolling, fall onto the second conveyor belt 403 via the second guide plate 211, the second conveyor belt 403, driven by the second drive motor 406, will move in a directional manner. The second conveyor belt 403 is equipped with multiple limiting strips 404, which will drive the Yunnan olives to continue moving towards the top of the other end of the pool 101. In addition, each of the multiple limiting strips 404 is provided with a strip-shaped drainage hole 405, so that the water sprayed by the subsequent high-pressure spray washing mechanism 5 can flow to the bottom of the pool 101 through the strip-shaped drainage hole 405, thereby realizing the rapid drainage of the washed Yunnan olives and preventing a large amount of washing water from being sent into the crushing and pulping mechanism 6 along with the Yunnan olives.

[0051] like Figure 6As shown, a high-pressure spray washing mechanism 5 corresponding to the lifting and conveying mechanism 4 is installed on one side of the top of the pool body 101. The high-pressure spray washing mechanism 5 includes a fixed frame 501 fixed to one side of the top of the pool body 101. A guide pipe 502 is installed between the front and rear ends of the inner wall of the fixed frame 501. Multiple evenly distributed high-pressure nozzles 503 are installed at the bottom end of the guide pipe 502. A water supply connector 504 communicating with the guide pipe 502 is provided at the rear end of the fixed frame 501. When the high-pressure water flow is connected to the water supply connector 504, the water flow will enter the guide pipe 502 through the water supply connector 504, and then be sprayed downward through the multiple high-pressure nozzles 503, thereby realizing a secondary high-pressure cleaning of the Yunnan olives on the second conveyor belt 403, so that the Yunnan olives can be cleaned more thoroughly.

[0052] On the side of the washing tank 1 away from the debris collection mechanism 3, a crushing and pulping mechanism 6, a heating and extraction mechanism 7, a filtration and separation mechanism 8, and a vacuum concentration mechanism 9 are arranged in sequence.

[0053] like Figures 10-11 As shown, the crushing and pulping mechanism 6 includes a crushing cylinder 601 located at the bottom of the guide frame 407. The bottom of the crushing cylinder 601 is arranged in an inverted cone shape. A fixed top cover 602 is fixedly installed on the top of the crushing cylinder 601. A crushing motor 603 is installed at the center of the top of the fixed top cover 602. A rotating shaft 604 is fixedly connected to the bottom of the output shaft of the crushing motor 603. Multiple sets of evenly distributed crushing blades 605 are fixedly installed on the outer wall of the rotating shaft 604. A feeding hole 606 is opened on one side of the top of the fixed top cover 602. A sliding cover 607 is slidably connected between the front and rear ends of the inner wall of the feeding hole 606. A top protective frame 608 is fixedly connected to the top side of the feeding hole 606. A first electric motor is installed at the center of the discharge port at the bottom of the crushing cylinder 601. A solenoid valve 609 is installed, and a first discharge pipe 610 is fixedly installed at the bottom center of the crushing cylinder 601. When the Yunnan olives move to the top position with the second conveyor belt 403, they will fall naturally and then roll into the crushing cylinder 601 through the guide frame 407. After all the materials are fed, the sliding cover 607 is slid to close the feeding hole 606. At this time, the crushing motor 603 is started. The output shaft of the crushing motor 603 will drive the rotating shaft 604 and multiple sets of evenly distributed crushing blades 605 to quickly crush the Yunnan olives in the crushing cylinder 601 to form a slurry. When the first solenoid valve 609 is opened, the first pump body 1001 can pump the slurry to the heating extraction mechanism 7 through the first discharge pipe 610 and the first feeding pipe 1002.

[0054] like Figures 12-13As shown, the heating extraction mechanism 7 includes a heating extraction tank 701 disposed on one side of the crushing and pulping mechanism 6. Multiple first support legs 702 are fixedly connected to the bottom edge of the heating extraction tank 701. A first tank cover 703 is installed on the top of the heating extraction tank 701. A through-hole first water inlet 704 is provided on one side of the top of the first tank cover 703. An electromagnetic heating coil 705 is installed at the center of the inner wall of the heating extraction tank 701. A second solenoid valve 706 is installed at the center of the bottom outlet of the heating extraction tank 701. A second discharge pipe 707 is installed at the bottom end of the second solenoid valve 706. After the slurry is introduced into the heating extraction tank 701, an appropriate amount of extraction solvent (ethanol, alcohol, distilled water, acetic anhydride or acetone, etc. can be selected according to actual needs) is added to the heating extraction tank 701 through the first water inlet 704. Soak for about one hour, and then heat the heating extraction tank 701 through the electromagnetic heating coil 705 to 75-80℃. Continue heating for 20 minutes and then stop heating. Then open the second solenoid valve 706, and the second pump body 1003 can pump the slurry through the second discharge pipe 707 and the second feeding pipe 1004 to the filtration and separation mechanism 8.

[0055] like Figures 14-15 As shown, the filtration and separation mechanism 8 includes a filtration and separation box 801 located on the other side of the heating extraction tank 701. A bottom support frame 802 is fixedly connected to the bottom of the filtration and separation box 801, and a support frame 803 is fixedly connected to the bottom of the inner wall of the filtration and separation box 801. A separable activated carbon filter box 804 is installed at the center of the support frame 803. A protective door 805 is rotatably connected to the front opening of the filtration and separation box 801, and a third solenoid valve 806 is installed at the center of the bottom outlet of the filtration and separation box 801. The bottom of the three solenoid valves 806 is equipped with a third discharge pipe 807. When the slurry is introduced into the filtration and separation box 801, the slurry also accumulates on the top of the activated carbon filter box 804. The activated carbon filter box 804 is equipped with activated carbon packs. After the liquid in the slurry is filtered by the activated carbon, it enters the bottom of the filtration and separation box 801 to form an extract. At this time, the third solenoid valve 806 is opened, and the third pump body 1005 can pump the extract through the third discharge pipe 807 and the third feeding pipe 1006 to the pressure reducing and concentrating mechanism 9.

[0056] like Figures 16-17As shown, the vacuum concentration mechanism 9 includes a concentration tank 901 located on one side of the filter separation box 801. Multiple second support legs 902 are fixedly connected to the bottom edge of the concentration tank 901. A second tank cover 903 is fixedly installed on the top of the concentration tank 901. A through second water inlet 904 is provided on one side of the top of the second tank cover 903. A fourth solenoid valve 905 is installed at the center of the bottom outlet of the concentration tank 901. A fourth discharge pipe 906 is installed at the bottom end of the fourth solenoid valve 905. When the extract enters the concentration tank 901, vacuum concentration of the extract can be performed (vacuum concentration technology is a mature existing technology, and its specific principles will not be detailed here). Finally, the fourth solenoid valve 905 is opened, and the viscous liquid after vacuum concentration flows out through the fourth discharge pipe 906. The liquid is collected and then dried to obtain a high-purity tannin product.

[0057] like Figures 1-3 As shown, the crushing and pulping mechanism 6, the heating and extraction mechanism 7, the filtration and separation mechanism 8, and the vacuum concentration mechanism 9 are connected by a pumping mechanism 10. The pumping mechanism 10 includes a first pump body 1001, a second pump body 1003, and a third pump body 1005. One end of the first discharge pipe 610 is connected to the inlet of the first pump body 1001, and the outlet of the first pump body 1001 is connected to a first feeding pipe 1002 that communicates with the first tank cover 703. One end of the second discharge pipe 707 is connected to the inlet of the second pump body 1003. The first pump body 1001, the second pump body 1003 and the third pump body 1005 are connected to each other. The outlet of the second pump body 1003 is connected to the second feeding pipe 1004, which is connected to the top of the filter separation box 801. One end of the third discharge pipe 807 is connected to the inlet of the third pump body 1005. The outlet of the third pump body 1005 is connected to the third feeding pipe 1006, which is connected to the top of the second tank cover 903. The first pump body 1001, the second pump body 1003 and the third pump body 1005 are mainly used to pump the slurry during the extraction process to realize automated production line processing.

[0058] The working principle of this embodiment is as follows: After soaking, Yunnan olives are poured into the pool 101. The first drive motor 206 drives the first drive roller 201 and the first conveyor belt 203 to rotate in a directional manner through its output shaft. Since the first conveyor belt 203 has multiple evenly distributed positioning holes 204, some of the Yunnan olives on the first conveyor belt 203 roll into the corresponding positioning holes 204. The diameter of the positioning holes 204 is larger than the average diameter of the Yunnan olives. The Yunnan olives falling into the positioning holes 204 will move synchronously with the first conveyor belt 203. Since a middle cleaning plate 207 is installed at the center of the first conveyor belt 203, and a top cleaning sponge 209 is provided at the bottom of the top fixing plate 208, and there is a certain gap between the middle cleaning plate 207, the top cleaning sponge 209 and the first conveyor belt 203, when the Yunnan olives move with the first conveyor belt 203, due to friction, the Yunnan olives will roll irregularly in the corresponding positioning holes 204, thereby continuously interacting with the middle cleaning plate 207 and the top cleaning sponge. Rolling friction occurs at 209, thus achieving automatic cleaning of the Yunnan olives and removing some impurities attached to their surface. When the Yunnan olives move to the top of the first conveyor belt 203, they fall naturally and are guided by the second guide plate 211 onto the lifting conveyor mechanism 4. After the rolling cleaning is completed, the Yunnan olives fall onto the second conveyor belt 403 via the second guide plate 211. Driven by the second drive motor 406, the second conveyor belt 403 moves in a directional manner. Multiple limiting strips 404 are provided on the belt 403. The multiple limiting strips 404 will drive the Yunnan olives to continue to move towards the top of the other end of the pool 101. A high-pressure spray washing mechanism 5 corresponding to the lifting conveyor mechanism 4 is installed on one side of the top of the pool 101. When the water supply connector 504 is connected to the high-pressure water flow, the water flow will enter the guide pipe 502 through the water supply connector 504, and then be sprayed downward through multiple high-pressure nozzles 503, thereby realizing the secondary high-pressure cleaning of the Yunnan olives on the second conveyor belt 403, so that the Yunnan olives can be cleaned more thoroughly.

[0059] When the Yunnan olives move to the top position along the second conveyor belt 403, they will fall naturally and then roll into the crushing cylinder 601 via the guide frame 407. Then, the crushing motor 603 drives the rotating shaft 604 and multiple sets of evenly distributed crushing blades 605 to quickly crush the Yunnan olives in the crushing cylinder 601 to form a slurry. When the first solenoid valve 609 is opened, the first pump body 1001 can pump the slurry through the first discharge pipe 610 and the first feeding pipe 1002 to the heating extraction mechanism 7.

[0060] After the slurry is introduced into the heating extraction tank 701, an appropriate amount of extraction solvent is added to the heating extraction tank 701 through the first water inlet 704. The tank is soaked for about one hour. Then, the heating extraction tank 701 is heated by the electromagnetic heating coil 705 to 75-80°C. The heating is stopped after 20 minutes. Then, the second solenoid valve 706 is opened and the second pump body 1003 can pump the slurry to the filtration and separation mechanism 8 through the second discharge pipe 707 and the second feeding pipe 1004.

[0061] After the slurry is introduced into the filtration and separation box 801, the slurry also accumulates on the top of the activated carbon filter box 804. The activated carbon filter box 804 is equipped with activated carbon packs. After the liquid in the slurry is filtered by the activated carbon, it enters the bottom of the filtration and separation box 801 to form an extract. At this time, the third solenoid valve 806 is opened, and the third pump body 1005 can pump the extract through the third discharge pipe 807 and the third feeding pipe 1006 to the pressure reducing and concentrating mechanism 9.

[0062] After the extract enters the concentration tank 901, the extract can be concentrated under reduced pressure. Finally, the fourth solenoid valve 905 is opened, and the viscous liquid after reduced pressure concentration will flow out through the fourth discharge pipe 906. The liquid is collected and then dried to obtain a high-purity tannin product.

[0063] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
