Description

Technical Field

[0001] This invention relates to the field of powdered phospholipid production technology, and more specifically, to a soybean phospholipid oil powder production apparatus based on microcapsule technology. Background Technology

[0002] Soybean phospholipid oil powder is a phospholipid product extracted from soybean oil. After processing, it exists in powder form. It is rich in nutrients such as phospholipids, triglycerides, choline, and inositol, and has excellent film-forming, emulsifying, and biodegradable properties.

[0003] Soybean lecithin oil powder is rich in unsaturated fatty acids, which will spontaneously oxidize upon exposure to air, producing harmful substances such as peroxides and aldehydes. Therefore, post-production packaging and sealing are crucial steps to ensure its quality stability, extend shelf life, and prevent oxidation and moisture absorption. Currently, common storage methods for soybean lecithin oil powder include vacuum aluminum foil bag packaging, PET / PE composite bag packaging, tin can packaging, and microencapsulation technology packaging.

[0004] Microencapsulation technology typically involves encapsulating soybean phospholipid oil powder to physically isolate it from air and moisture, thus stabilizing the phospholipids within the powder and effectively extending its shelf life. Therefore, microencapsulation technology has high practical value for preserving soybean phospholipid oil powder.

[0005] Currently, the industrial application of microencapsulation technology for preserving soybean lecithin oil powder requires high purity of the soybean lecithin oil powder. However, existing soybean lecithin oil powder production equipment produces soybean lecithin oil powder with low purity, containing excessive amounts of neutral lipids, proteins, sugars, and metal ions. This affects the formation of a uniform microencapsulation membrane on the soybean lecithin surface, resulting in an incomplete microencapsulation membrane. Therefore, before using microencapsulation technology to preserve soybean lecithin oil powder, it is usually necessary to purify the soybean lecithin oil powder first.

[0006] Commonly used purification methods in the prior art include solvent fractionation extraction, supercritical CO2 extraction, and short-path molecular distillation.

[0007] Solvent fractionation extraction typically uses acidic solutions as extractants for the hydration and degumming of crude soybean oil, such as hydrochloric acid, citric acid, and acetic acid. The introduction of acidic conditions can enhance the selective separation of phospholipids, thereby improving the purity of soybean phospholipid oil powder. However, after introducing acidic conditions, the solvent needs to be recovered by distillation after shutdown, and the equipment needs to be thoroughly cleaned between different batches to avoid cross-contamination. Therefore, continuous production cannot be achieved through solvent fractionation extraction for purification.

[0008] Supercritical CO2 extraction is a green separation technology that uses the high permeability and selective solubility of CO2 in the supercritical state to purify phospholipids. However, the investment and maintenance costs of high-pressure equipment are high, the seals are easily damaged and need to be replaced frequently, and after each batch, it is necessary to safely depressurize, repressurize and temperature equalize, which takes a long time. As a result, continuous material feeding and discharging cannot be achieved, and only intermittent operation is possible.

[0009] Short-path molecular distillation separates low-boiling-point components from phospholipids under high vacuum conditions, making it suitable for the purification of heat-sensitive substances. However, after distillation, the high molecular polymers or coking residues remaining in hydrated phospholipids will adhere to the surface of the evaporator, requiring periodic shutdowns for cleaning, and thus cannot operate continuously. Summary of the Invention

[0010] The purpose of this invention is to provide a soybean phospholipid oil powder production device based on microencapsulation technology, so as to improve the continuous operation capability of soybean phospholipid oil powder production equipment and reduce resource and energy consumption.

[0011] To solve the above problems, the present invention adopts the following technical solution.

[0012] A soybean lecithin oil powder production device based on microcapsule technology includes a tank. The tank is characterized by having, from top to bottom, a hydration and degumming section, an acid-base neutralization section, a centrifugation section, a falling film evaporation section, and a short-path distillation section. A conical tank for housing the hydration and degumming section and the acid-base neutralization section is fixedly installed at the top of the tank. A condensate recovery cylinder is fixedly installed at the bottom of the conical tank. Water vapor generated by the falling film evaporation section rises freely inside the tank and heats the hydration and degumming section and the acid-base neutralization section inside the conical tank. The condensate recovery cylinder collects condensate from the outer wall of the conical cylinder and is used to clean the centrifugation section. A solenoid valve for discharging condensate is installed at the bottom of the condensate recovery cylinder. The output end of the solenoid valve is fixedly connected to a water supply pipe connected to the centrifugation section. A wastewater discharge pipe is installed on the centrifugation section to discharge wastewater.

[0013] Existing technologies generally employ jacketed heating, which involves installing a jacket on the outer wall of the reaction vessel and circulating hot water through it to ensure uniform heating of the vessel wall. This improves the reaction efficiency of crude soybean oil during hydration, degumming, and acid-base neutralization reactions. While jacketed heating can effectively improve the reaction efficiency of crude soybean oil during hydration, degumming, and acid-base neutralization reactions, heating the hot water in the jacket requires a significant amount of energy.

[0014] In this invention, the hot steam generated during the operation of the falling film evaporation section is used to heat the hydration degumming section, the acid-base neutralization section, and the centrifugation section, thereby improving the efficiency of the hydration degumming reaction, the acid-base neutralization reaction, and the centrifugation separation while reducing energy consumption.

[0015] Optionally, the conical tank is provided with:

[0016] A first dividing plate, which is fixedly installed inside the conical tank, divides the conical tank into hydration and degumming chambers.

[0017] With acid-base neutralization chamber;

[0018] Inlet pipe 1: It is located at the top of the tank and passes through the tank to connect with the hydration and degumming chamber, and is used to pour the acidic solution into the hydration and degumming chamber;

[0019] Inlet pipe 2: It is located on one side of the tank and passes through the tank to connect with the acid-base neutralization chamber, and is used to pour alkaline solution into the acid-base neutralization chamber;

[0020] Stirring rod: It is rotatably mounted inside the conical tank and is used to stir the crude soybean oil, acidic solution and alkaline solution placed inside the conical tank;

[0021] Thrust balance disc: It is fixedly installed in the acid-base neutralization chamber to restrict the position of the bottom end of the stirring rod and reduce the centripetal force when the stirring rod rotates;

[0022] First drive motor: It is fixedly installed at the top of the tank and drives the stirring rod;

[0023] Propeller blade one: It is fixedly installed on a section of the stirring rod near the top of the first dividing plate, and is used to transport the solution in the hydration degumming chamber;

[0024] The second propeller blade, fixedly mounted on a section of the stirring rod near the top of the thrust balance disc, is used to transport the solution within the acid-base neutralization chamber.

[0025] Ball valve 1: It is fixedly installed at the bottom of the first partition plate and is used to control the entry and exit of the phospholipid mixture solution in the hydration degumming chamber;

[0026] Ball valve 2: It is fixedly installed at the bottom of the conical tank and is used to control the entry and exit of the acid-base neutralization chamber.

[0027] Infusion tube: It is fixedly installed at the output end of the ball valve and connected to the centrifuge section, and is used to transport the phospholipid mixture in the acid-base neutralization chamber to the centrifuge section for centrifugal separation.

[0028] Optionally, the centrifuge section includes:

[0029] Centrifuge: It is located at the bottom of the conical tank and is used to centrifuge the input phospholipid mixture solution;

[0030] Support base: It is fixedly installed at the bottom of the centrifuge to provide support for the centrifuge;

[0031] Solution transfer box: It is set at the bottom of the support base, and multiple connecting support rods are distributed circumferentially on the outer edge of the solution transfer box. The solution transfer box is fixedly set in the tank through the connecting support rods, and collects the hydrated phospholipids produced after the phospholipid mixture solution is centrifuged and separated by the centrifuge.

[0032] Phospholipid transport tube: It is fixedly installed at the bottom of the solution transfer tank and connected to the falling film evaporation section;

[0033] Recovery pipe one: It is located on the side near the top of the centrifuge and is used to recover the degummed soybean oil after centrifugation;

[0034] Phospholipid delivery pipe: It is located on one side near the middle of the centrifuge and is used to transport the hydrated phospholipids after centrifugation.

[0035] Recovery pipe 2: It is located on one side near the bottom of the centrifuge and is used to recover the neutralized waste liquid after centrifugation.

[0036] Ball valve three: It is fixedly installed at the inlet end of the phospholipid delivery pipe, the recovery pipe one, the phospholipid delivery pipe and the recovery pipe two, and is used to control the entry and exit of the solution after centrifugation.

[0037] In the existing technology, after the phospholipid mixture undergoes acid-base neutralization reaction and is centrifuged, a small amount of hydrated phospholipids and degummed soybean oil residues will still adhere to the inner wall of the centrifuge. After the centrifuge separates multiple phospholipid mixtures, the amount of hydrated phospholipids and degummed soybean oil adhering to the inner wall of the centrifuge will gradually increase. If they are not cleaned in time, it will affect the separation quality of subsequent phospholipid mixtures in the centrifuge. If the centrifuge is stopped to clean the hydrated phospholipids and degummed soybean oil adhering to the inner wall of the centrifuge, it will be detrimental to the continuous production of crude soybean oil.

[0038] In this invention, the steam discharged from the falling film evaporation section heats the conical tank, while the steam condenses on the outer wall of the conical tank to form condensate, which then flows into the condensate recovery cylinder for storage. Since the phospholipid mixture only takes 10-30 seconds to centrifuge, after the centrifuge has centrifuged a batch of phospholipid mixture, the phospholipid mixture in the hydration degumming section, acid-base neutralization section, falling film evaporation section, and short-path distillation section is still being processed. The centrifuge is idle for a considerable period of time. When the centrifuge is idle, it is only necessary to control the solenoid valve to open, allowing the condensate in the condensate recovery cylinder to flow into the centrifuge. Then, the centrifuge is started to clean the centrifuge with the condensate, and the condensate flows into the external wastewater recovery device through the wastewater discharge pipe on the centrifuge for recycling. Thus, it is not necessary to stop the centrifuge for cleaning.

[0039] Optionally, the short-path distillation section includes:

[0040] Short-path distiller: It is fixedly installed inside the tank and improves the purity of hydrated phospholipids by utilizing the difference in molecular free path.

[0041] Phospholipid discharge pipe: It is located at the bottom of the short-path distiller and extends through the tank to the outside to transport the purified hydrated phospholipid;

[0042] Hydrated phospholipid transfer tank: It is fixedly installed at the top of the short-path distiller to collect the hydrated phospholipid discharged from the falling film tube and discharge the hydrated phospholipid into the short-path distiller for further processing.

[0043] In existing technologies, hydrated phospholipids obtained by centrifugation are rich in neutral oil, hydrated phospholipids, water, and water-soluble impurities. If they are directly subjected to falling film evaporation, the sugars in the water-soluble impurities will caramelize at high temperatures to form brown solids that adhere to the tube walls of the falling film evaporator. Prolonged use will cause blockage of the falling film tubes. The soaps in the water-soluble impurities will decompose into fatty acids and alkalis at high temperatures, causing unnecessary corrosion of the falling film tubes. On the other hand, the neutral oil in hydrated phospholipids can be reprocessed into crude oil, biodiesel feedstock, industrial-grade oils, phospholipid supplements, etc. The water and water-soluble impurities in hydrated phospholipids can be used for phospholipid recovery, water reuse, fermentation culture media, and agricultural irrigation. Directly performing falling film evaporation on hydrated phospholipids will result in unnecessary waste of resources.

[0044] In this invention, the hydrated phospholipid discharged into the solution settling box is allowed to settle and separate into three layers inside the solution settling box: neutral oil, hydrated phospholipid, water, and water-soluble impurities. These layers are then discharged and collected through the first and second liquid recovery pipes, making full use of the resources. At the same time, since the hydrated phospholipid obtained after settling contains only a small amount of neutral oil, water, and water-soluble impurities, it is less likely to cause blockage and corrosion of the falling film evaporator tube wall during the falling film evaporation process.

[0045] Optionally, a settling and recovery section is provided between the centrifugation section and the falling film evaporation section. The settling and recovery section includes a solution settling box located at the bottom of the solution transfer tank. The support base is fixedly installed on the solution settling box.

[0052] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0053] 1. The present invention sets the hydration degumming section and the acid-base neutralization section inside a conical tank, and uses the hot steam generated by the falling film evaporation section to heat the mixed solution reacting in the hydration degumming section and the acid-base neutralization section, thereby improving the efficiency of the hydration degumming reaction, the acid-base neutralization reaction and the centrifugal separation while reducing energy and resource consumption.

[0054] 2. This invention collects condensate generated by the condensation of hot steam through a conical tank, a condensate recovery cylinder, a solenoid valve, and a water supply pipe. When the centrifuge is idle, the solenoid valve is opened to deliver the condensate through the water supply pipe into the centrifuge, and the centrifuge is started. The condensate cleans the inside of the centrifuge, causing the hydrated phospholipids and degummed soybean oil adhering to the inner wall of the centrifuge to fall off and flow into the wastewater recovery device through the wastewater discharge pipe on the centrifuge. Thus, the internal cleaning of the centrifuge is completed while maintaining the normal operation of the equipment, effectively ensuring the continuous operation capability of the equipment.

[0055] 3. This invention, through the solution settling box, allows hydrated phospholipids to separate into three layers within the settling box: neutral oil, hydrated phospholipids, water, and water-soluble impurities. The neutral oil, water, and water-soluble impurities are discharged and collected through the first and second liquid recovery pipes, thus making full use of resources. At the same time, since the hydrated phospholipids obtained after settling contain only a small amount of neutral oil, water, and water-soluble impurities, they are less likely to cause blockage and corrosion of the falling film evaporator tube walls during the falling film evaporation process. Therefore, it is not necessary to frequently shut down the equipment to clean the caramelized solids adhering to the falling film evaporator tube walls, further improving the continuous operation capability of the equipment.

[0082] Example 1

[0083] This invention provides a soybean phospholipid oil powder production device based on microencapsulation technology, such as... Figure 1-3 As shown, it includes a tank body 1, and inside the tank body 1, from top to bottom, there are a hydration degumming section 2, an acid-base neutralization section 3, a centrifugation section 4, a falling film evaporation section 5, and a short-path distillation section 6.

[0084] A conical tank 8 is fixedly installed at the top of the tank body 1. A condensate recovery cylinder 9 is fixedly installed at the bottom of the conical tank 8. A solenoid valve 10 for discharging condensate is installed at the bottom of the condensate recovery cylinder 9. The output end of the solenoid valve 10 is fixedly connected to a water supply pipe 11 that communicates with a centrifuge section 4. A wastewater discharge pipe 12 for discharging wastewater is installed on the centrifuge section 4. A first partition plate 13 is fixedly installed inside the conical tank 8, dividing the conical tank 8 into a hydration degumming chamber 14 and an acid-base neutralization chamber 15. The hydration degumming section 2 and the acid-base neutralization section 3 are respectively installed in the hydration degumming chamber 14 and the acid-base neutralization chamber 15. A liquid inlet pipe 16 and a liquid inlet pipe 17 are respectively installed on the tank body 1. The liquid inlet pipe 16 is fixedly installed at the top of the tank body 1 and passes through the tank body 1 to communicate with the hydration degumming chamber 14. The liquid inlet pipe 17 is fixedly installed on one side of the tank body 1 and passes through the tank body 1 to communicate with the acid-base neutralization chamber 15. The conical tank 8 is connected to the centrifuge. A stirring rod 18 is rotatably installed inside the conical tank 8. A thrust balance plate 19 is fixedly installed on the side of the acid-base neutralization chamber 15 away from the first partition plate 13. One end of the stirring rod 18 away from the thrust balance plate 19 passes through the tank body 1 and is connected to the first drive motor 20. The other end of the stirring rod 18 passes through the first partition plate 13 and is rotatably connected to the thrust balance plate 19. The stirring rod 18, the conical tank 8, the first partition plate 13 and the thrust balance plate 19 are all coaxially arranged. A propeller blade 1 21 is fixedly installed on the section of the stirring rod 18 near the top of the first partition plate 13. A propeller blade 22 is fixedly installed on the side of the stirring rod 18 near the top of the thrust balance plate 19. A ball valve 1 23 is installed at the bottom of the first partition plate 13. A ball valve 24 is fixedly installed at the bottom of the conical tank 8. A liquid delivery pipe 25 is fixedly connected to the output end of the ball valve 24. A wastewater discharge pipe 12 is installed on the centrifuge section 4 to discharge wastewater.

[0085] It should be noted that when not in use, the inlet can be sealed with an end cap connected to its top thread to prevent external dust or impurities from flowing into the hydration degumming chamber 14 and the acid-base neutralization chamber 15. Furthermore, the actual volume of the acid-base neutralization chamber 15 is larger than that of the hydration degumming chamber 14. The outlet of the inlet connected to the acid-base neutralization chamber 15 is located at the top of the acid-base neutralization chamber 15, so that after the phospholipid mixture in the hydration degumming chamber 14 is discharged into the acid-base neutralization chamber 15, the liquid level is lower than the height of the outlet end of the inlet. This prevents the phospholipid mixture in the acid-base neutralization chamber 15 from flowing into the inlet during the acid-base neutralization process, ensuring the stable operation of the device. On the other hand, adding an acidic solution during the hydration degumming process of crude soybean oil can effectively increase the precipitation rate of phospholipids in crude soybean oil, thereby improving the purity of soybean phospholipid oil powder after production.

[0086] On the other hand, the end of the wastewater discharge pipe 12 away from the centrifuge 401 passes through the tank 1 and is connected to the external wastewater recovery device. When cleaning the impurities attached to the centrifuge 401, the steam discharged from the falling film evaporator 5 will heat the conical tank 8 and condense on the outer wall of the conical tank 8 to form condensate, which then flows into the condensate recovery cylinder 9 for storage. When the centrifuge 401 finishes working, it is only necessary to control the solenoid valve 10 to open so that the condensate in the condensate recovery cylinder 9 flows into the centrifuge 401, and then start the centrifuge 401 to clean the centrifuge 401 with condensate, and then flow into the external wastewater recovery device for recovery through the wastewater discharge pipe 12 set on the centrifuge 401. Thus, it is not necessary to stop the centrifuge 401 for cleaning. It is only necessary to use the condensate collected in the condensate recovery cylinder 9 to clean the centrifuge 401 when the centrifuge 401 is idle, which effectively ensures the continuous operation capability of the centrifuge 4.

[0087] Reference Figure 2-3 As shown, the centrifuge section includes a centrifuge 401 located at the bottom of the conical tank 8. The centrifuge 401 is equipped with a recovery pipe 404 (first recovery pipe), a phospholipid delivery pipe 405, and a recovery pipe 406 for recovering the centrifuged and separated solution. The recovery pipe 404 is fixedly located near the top of the centrifuge 401, the phospholipid delivery pipe 405 is fixedly located near the middle of the centrifuge 401, and the recovery pipe 406 is fixedly located near the bottom of the centrifuge 401. Both the recovery pipe 404 and the recovery pipe 406 extend through the tank 1 to the outside. The phospholipid delivery pipe 405 passes through the support base 402 and the solution... The transfer box 403 is connected. Ball valve 3 407 is fixedly installed at the inlet end of the recovery pipe 1 404, phospholipid delivery pipe 405 and recovery pipe 2 406. A support base 402 is fixedly installed at the bottom of the centrifuge 401 to support it. The solution transfer box 403 is fixedly installed at the bottom of the support base 402. Multiple connecting support rods 409 are arranged circumferentially at the outer edge of the solution transfer box 403. The solution transfer box 403 is fixedly installed in the tank 1 through the connecting support rods 409. A phospholipid delivery pipe 410 for transporting the phospholipid mixture is provided at the bottom of the solution transfer box 403.

[0088] It should be noted that in this embodiment, centrifuge 401 is a three-phase disc centrifuge 401. The phospholipid mixture entering the three-phase disc centrifuge 401 is centrifuged and separated into a light phase degummed soybean oil, a medium phase hydrated phospholipid, and a heavy phase neutralization waste liquid. Recovery pipes located at the top and bottom of the three-phase disc centrifuge 401 are respectively connected to recovery devices to recover the degummed soybean oil and neutralization waste liquid. The degummed soybean oil collected in the recovery devices can be used for direct industrial applications, food-grade recycling, agricultural and feed applications, and high-value-added uses. The neutralized waste liquid can be tested. If its pH value, COD content, phosphate content, and oil content all meet the discharge standards, the neutralized waste liquid can be discharged directly. If any of the pH value, COD content, phosphate content, or oil content in the neutralized waste liquid does not meet the direct discharge standards, the neutralized waste liquid must be treated accordingly before it can be discharged to reduce damage to the natural environment. The recovery pipe located in the middle of the centrifuge 401 transports the hydrated phospholipid in the three-phase disc centrifuge 401 to the solution transfer tank 403 for subsequent processing.

[0089] Reference Figure 3 As shown, the falling film evaporation unit 5 includes a falling film evaporator 501 disposed at the bottom of the conical sleeve 722. A rotating scraper 502 is rotatably disposed on the falling film evaporator 501. A second drive motor 503 is disposed at the top of the falling film evaporator 501 to drive the rotating scraper 502. A second partition plate 504 is fixedly disposed inside the falling film evaporator 501, dividing the falling film evaporator 501 into a scraping chamber 505 and a heating chamber 506. A plurality of falling film tubes 508 are disposed inside the heating chamber 506. The top ends of the falling film tubes 508 pass through the second partition plate 504 and are connected to the scraping chamber 505. An external heating device is connected to the heating chamber 506 to heat the tubes. The heat source 507 and the heating chamber 506 have multiple steam outlet holes 509 on the bottom side to facilitate the flow of water vapor. The short-path distillation section 6 includes a short-path distiller 601 fixedly installed at the bottom of the falling film evaporator 501. The short-path distiller 601 is fixedly installed inside the tank body 1. The bottom of the short-path distiller 601 is provided with a phospholipid discharge pipe 602 that penetrates the bottom of the tank body 1. The top of the short-path distiller 601 is fixedly provided with a hydrated phospholipid transfer box 603 for collecting hydrated phospholipids. The top of the hydrated phospholipid transfer box 603 is connected to multiple falling film pipes 508. The bottom of the hydrated phospholipid transfer box 603 is provided with a way to discharge hydrated phospholipids into the short-path distiller 601.

[0090] It should be noted that a ball valve is provided at the bottom drain end of the hydrated phospholipid transfer tank 603, which is connected to the inlet end of the short-path distiller 601, to control whether the hydrated phospholipid in the hydrated phospholipid transfer tank 603 flows into the short-path distiller 601 and to control the flow rate of the hydrated phospholipid.

[0091] In use, crude soybean oil is poured into the conical tank 8 through the inlet pipe 16 on the tank body 1. Then, according to the total amount of crude soybean oil poured in, an acidic solution is poured in through the inlet. The first drive motor 20 is then started, driving the stirring rod 18 to rotate within the hydration and degumming chamber 14 and the acid-base neutralization chamber 15. After the hydration and degumming reaction of the crude soybean oil is complete, the ball valve 23 opens. The propeller blade 21 on the stirring rod 18, under the rotation of the stirring rod 18, transports the phospholipid mixture solution in the hydration and degumming chamber 14, allowing it to flow into the acid-base neutralization chamber 15 through the ball valve 23. After the phospholipid mixture solution in the hydration and degumming chamber 14 has completely flowed into the acid-base neutralization chamber 15, the first drive motor 20 stops, and the ball valve 23 closes. At this point, the solution is poured in through the inlet pipe 16 on the tank body 1. Soybean oil and a suitable amount of acidic solution are poured into the hydration and degumming chamber 14 again through pipe 16, and a suitable amount of alkaline solution is poured into the acid-base neutralization chamber 15 through inlet pipe 27. This neutralizes the acidic solution in the phospholipid mixture, balancing the pH value of the phospholipid mixture. Then, the first drive motor 20 is restarted to drive the stirring rod 18 to rotate in the hydration and degumming chamber 14 and the acid-base neutralization chamber 15, increasing the reaction rate of the hydration and degumming reaction and the acid-base neutralization reaction. After the acid-base neutralization reaction of the phospholipid mixture is completed, ball valve 24 is opened, and the propeller blade 22 on the stirring rod 18 will transport the phospholipid mixture in the acid-base neutralization chamber 15 under the rotation of the stirring rod 18, allowing it to flow into the centrifuge through ball valve 24 and inlet pipe 25. Centrifugation is performed within centrifuge 401. Since the single-pass time for centrifuging the phospholipid mixture solution is only 10-30 seconds, the stirring rod 18 and propeller blade 21 do not affect the acid-base neutralization effect within the neutralization chamber 15 during the process of transferring the phospholipid mixture solution from the neutralization chamber 15 to centrifuge 401. After all the phospholipid mixture solution in the neutralization chamber 15 has been transferred to centrifuge 401, ball valve 23 opens, and the phospholipid mixture solution in the hydration and degumming chamber 14 flows into the neutralization chamber 15 under the transport of propeller blade 21. Then, the first drive motor 20 stops, ball valve 23 closes, and the mixture flows again along the opening on tank 1. Soybean oil and a suitable amount of acidic solution are poured into the hydration and degumming chamber 14 through inlet pipe 16, and a suitable amount of alkaline solution is poured into the acid-base neutralization chamber 15 through inlet pipe 27. Then, the first drive motor 20 is started, driving the stirring rod 18 to rotate in the hydration and degumming chamber 14 and the acid-base neutralization chamber 15 to increase the reaction rate of the hydration and degumming reaction and the acid-base neutralization reaction. During this process, the phospholipid mixture separated by centrifugation in centrifuge 401 is divided into three layers: the upper layer is degummed soybean oil, the middle layer is hydrated phospholipids, and the lower layer is neutralization waste liquid. The upper layer of degummed soybean oil flows into the externally installed recovery device through ball valve 3 407 and recovery pipe 1 404, and the lower layer of neutralization waste liquid flows into the externally installed recovery device through ball valve 3 407 and recovery pipe 2 406.The hydrated phospholipids in the middle layer flow into the solution transfer tank 403 through ball valve 3 407 and phospholipid delivery pipe 405, and then flow into the falling film evaporator 501 through the phospholipid delivery pipe 410 at the bottom of the solution transfer tank 403 for falling film evaporation to further purify the phospholipid mixture. During the falling film evaporation purification process, the hot steam discharged from the external heat source 507 into the heating chamber 506 flows out of the heating chamber 506 through the steam discharge hole 509, and heats the inside of the tank 1, so that the hydration degumming section 2, acid-base neutralization section 3 and centrifugation section are heated. The temperature of the phospholipid mixture processed in section 4 is increased to improve the efficiency of the hydration degumming reaction, acid-base neutralization reaction, and centrifugal separation. The hydrated phospholipids, purified by evaporation in the falling film evaporation section 5, flow under gravity through multiple falling film pipes 508 into the hydrated phospholipid transfer tank 603. Then, through a ball valve at the bottom of the hydrated phospholipid transfer tank 603, they flow into the short-path still 601 for further purification and are discharged through the phospholipid discharge pipe 602 at the bottom of the short-path still 601, thus completing the production and processing of soybean phospholipid oil powder.

[0092] When cleaning impurities attached to the centrifuge 401, the steam discharged from the falling film evaporator 5 heats the conical tank 8 and condenses on the outer wall of the conical tank 8 to form condensate, which then flows into the condensate recovery tank 9 for storage. When the centrifuge 401 finishes working, it is only necessary to control the solenoid valve 10 to open so that the condensate in the condensate recovery tank 9 flows into the centrifuge 401. Then, the centrifuge 401 is started so that the condensate cleans the centrifuge 401 and flows into the external wastewater recovery device for recycling through the wastewater discharge pipe 12 set on the centrifuge 401.

[0093] Example 2

[0094] This embodiment further optimizes upon Embodiment 1. The hydrated phospholipids obtained by centrifuge 401 are rich in neutral oil, hydrated phospholipids, water, and water-soluble impurities. If they are directly subjected to falling film evaporation, the free fatty acids in the hydrated phospholipids will oxidize at high temperatures to generate harmful gases such as aldehydes and ketones. Furthermore, the sugars in the water-soluble impurities will caramelize at high temperatures to form brown solids that adhere to the tube walls of the falling film evaporator. Prolonged use will cause blockage of the falling film tube 508. The soaps in the water-soluble impurities will decompose into fatty acids and alkalis at high temperatures, leading to unnecessary corrosion of the falling film tube 508. On the other hand, the neutral oils in the hydrated phospholipids can be reprocessed into crude oil, biodiesel feedstock, industrial-grade oils, phospholipid supplements, etc. The water and water-soluble impurities in the hydrated phospholipids can be used for phospholipid recovery, water reuse, fermentation culture media, and agricultural irrigation. Directly subjecting the hydrated phospholipids to falling film evaporation would result in unnecessary waste of resources.

[0095] Reference Figure 3-18As shown, a settling and recovery section 7 is provided between the centrifuge section 4 and the falling film evaporation section 5. The settling and recovery section 7 includes a solution settling tank 701 located at the bottom of the solution transfer tank 403. A support base 402 is fixedly located at the top of the solution settling tank 701. Multiple settling modules 702 for facilitating solution settling are fixedly arranged inside the solution settling tank 701. A base plate 703 is fixedly connected to the bottom of the multiple settling modules 702. A turntable 704 is rotatably arranged at the bottom of the solution transfer tank 403. A first ball bearing assembly 705 is circumferentially arranged at the outer edge of the turntable 704. A first ball bearing groove 706 matching the first ball bearing assembly 705 is opened on the solution transfer tank 403. The bottom center of the turntable 704 is connected to the first reducer 707 and the third drive motor 708. The turntable 704 is fixedly equipped with a first rotor pump 709 to facilitate the discharge of hydrated phospholipids. The output end of the first rotor pump 709 is flush with the top of the solution settling tank 701. The solution settling tank 701 is equipped with a plurality of transfer tubes 710 that cooperate with the output end of the first rotor pump 709. The transfer tubes 710 are movably locked at the top of the solution settling tank 701. The transfer tubes 710 are equipped with a plurality of first compression springs 711. The two ends of the first compression springs 711 abut against the outer edge of the transfer tubes 710 and the top wall of the solution settling tank 701, respectively.

[0096] A sealing block 712 is provided on one side of multiple transfer tubes 710 to seal them. A guide slider 713 is fixedly provided at the end of the sealing block 712 away from the transfer tube 710. A connecting rod 714 is fixedly provided at the end of the guide slider 713 away from the sealing block 712. A first rotating shaft 715 is fixedly connected to the bottom of the end of the connecting rod 714 away from the guide slider 713. The solution settling tank 701 is provided with a way to facilitate the connection of the guide slider 713, the connecting rod 714 and the first rotating shaft 715. The first rotating shaft 715 is installed in the mounting groove 716. Both ends of the first rotating shaft 715 are rotatably set on the inner wall of the mounting groove 716. The guide slider 713 and the connecting rod 714 are slidably locked in the mounting groove 716 with the first rotating shaft 715 as the center. The guide slider 713 is located in the mounting groove 716. Both sides of the guide slider 713 are fixedly abutted against the arc spring 717. The two ends of the arc spring 717 are fixedly connected to the guide slider 713 and the inner wall of the mounting groove 716, respectively.

[0097] It should be noted that the outer edge of the top of the transfer tube 710 is tapered, narrower at the top and wider at the bottom, to cooperate with the multiple first compression springs 711 fixedly connected to its bottom. This allows the transfer tube 710 to gradually compress the first compression springs 711 under the pressure of the output end of the first rotor pump 709 and the sealing block 712, causing it to contract. This ensures that the transfer tube 710 remains contracted within the solution settling tank 701 until it is flush with the top of the solution settling tank 701. At this point, the transfer tube 710, under the action of the first compression springs 711, will always be in contact with the output end of the first rotor pump 709 or the sealing block 712, ensuring that the transfer tube 710 is in close contact with the output end of the first rotor pump 709 and the sealing block 712. The 12 sections have good sealing properties to prevent hydrated phospholipid from flowing out of the gap between the output end of the first rotor pump 709 and the transfer pipe 710 during transportation, or to prevent water vapor generated by the falling film evaporation section 5 from flowing into the solution settling tank 701 through the gap between the transfer pipe 710 and the sealing block 712, so that the solution settling tank 701 can maintain good sealing. In addition, when the top of the transfer pipe 710 is flush with the top of the solution settling tank 701, its bottom end is lower than the bottom plane of the top of the solution settling tank 701, thereby preventing the hydrated phospholipid flowing through the transfer pipe 710 from flowing into the groove where the first compression spring 711 is installed through the bottom end of the transfer pipe 710, effectively ensuring the utilization rate of resources.

[0098] On the other hand, the cross-sectional dimension of the sealing block 712 is larger than that of the transfer tube 710, so that the sealing block 712 can fit perfectly against the surface of the transfer tube 710 to seal it. This prevents water vapor generated by the falling film evaporation section 5 from flowing into the solution settling tank 701 through the gap between the sealing block 712 and the transfer tube 710, thus preventing water vapor from combining with the hydrated phospholipid and further controlling the water content inside the hydrated phospholipid, effectively ensuring the purity of the hydrated phospholipid. When the arc spring 717 is in a free state, its extension position causes the guide slider 713 to be located at the middle of the outer edge of the mounting groove 716. At this time, the sealing block 712 fixedly connected to the guide slider 713 fits against the surface of the transfer tube 710 to seal it. When the guide slider 713 is squeezed by the output end of the first rotor pump 709, the arc springs 717 on both sides of the guide slider 713 are subjected to compression and tension forces respectively, causing the guide slider 713 to slide inside the mounting groove 716 with the first rotating shaft 715 as the center, and driving the sealing block 712 to disengage from the transfer tube 710, so that the output end of the first rotor pump 709 covers the transfer tube 710, so as to transport the hydrated phospholipid to the settling module 702 for settling. Moreover, the elastic force of the arc spring 717 is greater than the elastic force of the first compression spring 711, so that when the sealing block 712 is reset, it squeezes the transfer tube 710, causing it to retract into the solution settling tank 701 and abut against the bottom wall of the sealing block 712.

[0099] Reference Figure 5-7 and Figure 11-13 As shown, the settling module 702 includes multiple solution settling boxes 718 inclinedly arranged on the solution settling tank 701. The solution settling boxes 718 are distributed circumferentially on the solution settling tank 701. Multiple drain pipes 719 are provided on the solution settling boxes 718 to facilitate solution discharge. Multiple partition baffles 720 are movably mounted inside the solution settling boxes 718. The outer ends of the partition baffles 720 abut against the second compression springs 721. The two ends of the second compression springs 721 are respectively connected to the partition baffles 720 and the solution settling boxes. The outer walls of the box 718 abut against each other. The bottom of the solution settling box 701 is provided with a conical sleeve 722. The conical sleeve 722 is provided with an airbag compression assembly 723 that compresses the partition baffles 720. The opposite ends of the multiple partition baffles 720 are provided with mutually cooperating plug-in ends 724. The upper and lower sides of the plug-in ends 724 are provided with limiting bars 725 that restrict the movement position of the partition baffles 720. The multiple partition baffles 720 divide the solution settling box 718 into multiple solution storage chambers 726.

[0100] A sliding block 727 is fixedly installed at the top of the conical sleeve 722. A second ball bearing assembly 728 is rotatably mounted on the sliding block 727. A sliding groove 729 matching the sliding block 727 and the second ball bearing assembly 728 is provided on the solution settling tank 701. The conical sleeve 722 is rotatably mounted at the bottom end of the solution settling tank 701 via the sliding block 727 and the second ball bearing assembly 728. A third ball bearing assembly 730 is rotatably mounted at the bottom end of the base plate 703. A second ball bearing groove 731 matching the third ball bearing assembly 730 is provided on the conical sleeve 722. The base plate 703 is rotatably mounted at the bottom end of the conical sleeve 722 via the third ball bearing assembly 730. On the conical sleeve 722, a first waste liquid recovery tank 732 and a second waste liquid recovery tank 733 are respectively provided on the solution settling tank 701 and the conical sleeve 722 for recycling and storing waste liquid. Multiple fixing plates 734 are arranged on the outer circumference of the first waste liquid recovery tank 732. The first waste liquid recovery tank 732 fixes the solution settling tank 701 in the tank body 1 through the multiple fixing plates 734. The second waste liquid recovery tank 733 is rotatably mounted on the conical sleeve 722. Multiple first liquid recovery pipes 735 and multiple second liquid recovery pipes 736 are respectively provided on the first waste liquid recovery tank 732 and the second waste liquid recovery tank 733.

[0101] It should be noted that the airbag compression assembly 723 adopts existing technology, such as an airbag plus an inflation component. When it is necessary to separate the solution settling box 718, it is only necessary to control the inflation component to inflate the airbag, so that the airbag compresses the separating baffle 720. This causes the separating baffles 720, which are slidably locked on both sides of the solution settling box 718, to gradually move closer to the solution settling box 718 and abut against each other, dividing the solution settling box 718 into three chambers. This completely separates the neutral oil, hydrated phospholipids, water, and water-soluble impurities after settling and stratification within the solution settling box 718, allowing for the classification and treatment of neutral oil, hydrated phospholipids, water, and water-soluble impurities. Furthermore, compared to a vertically set solution settling box 718, the inclined solution settling box 718 only needs to move a horizontal projection distance along the inclined surface, driving the heavy phase solution to slide downwards along the inclined surface, while the light phase solution gathers upwards, forming a dynamic separation interface. To accelerate the settling and stratification of hydrated phospholipids, sealing rubber gaskets are provided at the outer edges of the mating insertion ends 724 of the partition baffles 720 to enhance their sealing performance. This makes the partition baffles 720 fit more tightly, preventing the solution in one solution storage chamber 726 from flowing into the solution storage chamber 726 being aspirated through the gap between the partition baffles 720 when the solution in one solution storage chamber 726 is being aspirated. This effectively ensures the isolation effect of the partition baffles 720 on the solution. Furthermore, the mating insertion ends 724 of the two partition baffles 720 have a wedge-shaped block at one end that is narrow at the front and wide at the back, and a wedge-shaped groove at the other end that matches the wedge-shaped block. This makes the mating process of the two partition baffles 720 smoother and provides support for each other after mating, overcoming the bending of the partition baffles 720 due to their own weight, so that the two partition baffles 720 can always maintain a good fit.

[0102] On the other hand, the conical sleeve 722 is rotatably locked at the bottom of the solution settling tank 701 and is coaxially arranged with the solution settling tank 701. Simultaneously, the sliding engagement between the sliding block 727 fixed at the top of the conical sleeve 722, the second ball bearing assembly 728 and the sliding groove 729, and the sliding engagement between the third ball bearing assembly 730 fixed at the bottom of the conical sleeve 722 and the second ball bearing groove 731 reduces the movement resistance of the conical sleeve 722 when rotating on the solution settling tank 701 and the base plate 703, improving the smoothness of the conical sleeve 722's rotation. The first waste liquid recovery tank 732 and the second waste liquid recovery tank 733 are both rotatably mounted on the conical sleeve 722. Furthermore, the first waste liquid recovery tank 732 is connected to the solution settling tank 701 by multiple fixing plates 734 arranged circumferentially on its outer side. 1. Fixedly installed inside the tank 1, it also provides support for the centrifuge 4, so that the centrifuge 401 remains stable when rotating. The outer sides of the first waste liquid recovery tank 732 and the second waste liquid recovery tank 733 are respectively provided with a first liquid guide pipe and a second liquid guide pipe penetrating the tank 1. The ends of the first liquid guide pipe and the second liquid guide pipe extending outside the tank 1 are respectively connected to a recovery device for collecting neutral oil, water and water-soluble impurities. The second waste liquid recovery tank 733 is kept relatively stationary with the tank 1 through the second liquid guide pipe penetrating the tank 1, so that when the conical sleeve 722 rotates under the drive of the second reducer 758 and the fourth drive motor 753, the conical sleeve 722 can maintain its own rotation without driving the first waste liquid recovery tank 732 and the second waste liquid recovery tank 733 to rotate.

[0103] Reference Figure 13-15As shown, the conical sleeve 722 is provided with a phospholipid guide tube 737 that cooperates with the drain pipe 719. The phospholipid guide tube 737 is provided with a first telescopic sleeve 738 that cooperates with the drain pipe 719. The first telescopic sleeve 738 includes a first fixed tube 739 and a first telescopic tube 740. The first telescopic tube 740 is located at one end of the first fixed tube 739 and is slidably locked outside the first fixed tube 739. A first guide block 741 is fixedly provided at the end of the first telescopic tube 740 near the first fixed tube 739. The top of the first guide block 741 is threadedly connected to a first adjusting screw 742. The conical sleeve 722 is provided with multiple second telescopic sleeves 743 that mate with the drain pipe 719, the first liquid recovery pipe 735, and the second liquid recovery pipe 736. Each of the drain pipe 719, the first liquid recovery pipe 735, and the second liquid recovery pipe 736 is fixedly provided with sealing plates 744 that match the ends of the first telescopic sleeve 738 and the second telescopic sleeve 743. The second telescopic sleeve 743 includes a second fixed tube 74. 5. The second telescopic tube 746 is located at both ends of the second fixed tube 745 and is slidably locked outside the second fixed tube 745. A second guide block 747 is fixedly installed at one opposite end of each of the two second telescopic tubes 746. A second adjusting screw 748 is threadedly connected to the top of the second guide block 747. Both ends of the second adjusting screw 748 are rotatably mounted on the tapered sleeve 722. A first synchronous pulley 749 is fixedly installed on both the first adjusting screw 742 and the second adjusting screw 748. A timing belt 750 is fitted around the first timing pulley 749. A second timing pulley 751 is fitted around the end of the timing belt 750 away from the first timing pulley 749. A second rotating shaft 752 is fixedly installed in the middle of the second timing pulley 751. The second rotating shaft 752 is rotatably installed in the conical sleeve 722. A fourth drive motor 753 is fixedly installed at one end of one of the second rotating shafts 752. A gear 754 is fixedly installed on the second rotating shaft 752. A toothed belt 755 meshes with the outside of the multiple gears 754.

[0104] It should be noted that ball valves are installed on the first liquid recovery pipe 735, the second liquid recovery pipe 736, and the drain pipe 719 to close them, thereby preventing accidental leakage of the solution in the first waste liquid recovery tank 732, the second waste liquid recovery tank 733, and the solution settling box 718 when they are not connected to the second telescopic sleeve 743. The number of first liquid recovery pipes 735 and second liquid recovery pipes 736 on the first waste liquid recovery tank 732 and the second waste liquid recovery tank 733 corresponds to the number of solution settling boxes 718. The ends of the first liquid recovery pipes 735 and second liquid recovery pipes 736 near the conical sleeve 722 are respectively embedded in the first waste liquid recovery tank 732 and the second waste liquid recovery tank 733 to prevent contact between the first liquid recovery pipes 735 and the second liquid recovery pipes 736 when the conical sleeve 722 rotates. To prevent unnecessary motion interference, the threads on the second adjusting screw 748 are designed with two sections of opposite directions of rotation. This allows the two second guide blocks 747 connected to the threads on the second adjusting screw 748 to move simultaneously in opposite or opposite directions when the second adjusting screw 748 rotates. This allows the second telescopic tube 746, which is fixedly connected to the bottom of the second guide block 747, to extend and retract on the second fixed tube 745 accordingly. The threads on the first adjusting screw 742 have the same direction of rotation and the same pitch as the threads on one section of the first adjusting screw 748. This allows the second guide plate connected to the threads on the first adjusting screw 742 to move the same distance as the first guide plate connected to the threads on the second adjusting screw 748. Furthermore, the edge of the toothed belt 755 is parallel to the generatrix of the tapered sleeve 722, allowing the second rotating shaft 752, gear 754, and toothed belt 755 to be installed and operate normally within the tapered sleeve 722.

[0105] In use, the fourth drive motor 753 is started, causing the second rotating shaft 752 to rotate, which in turn drives the gear 754 on the second rotating shaft 752 to rotate. Then, through the toothed belt 755 sleeved on the outside of the gear 754, the three second rotating shafts 752 rotate synchronously. This causes the second rotating shaft 752 to drive the first synchronous pulley 749 to rotate through the second synchronous pulley 751 fixed in its middle and the synchronous belt 750 sleeved on the outside of the second synchronous pulley 751. This causes the first synchronous pulley 749 to drive the first adjusting screw 742 and... The second adjusting screw 748 rotates within the tapered sleeve 722, causing the first guide block 741 and the second guide block 747, which are threadedly connected to the first adjusting screw 742 and the second adjusting screw 748, to drive the first telescopic tube 740 and the second telescopic tube 746, which are fixedly connected to their bottoms, to extend and retract on the first fixed tube 739 and the second fixed tube 745 respectively, thereby causing the first telescopic tube 740 to be inserted into the drain pipe 719 and the second telescopic tube 746 to be inserted into the first liquid recovery pipe 735, the second liquid recovery pipe 736, and the drain pipe 719.

[0106] Reference Figure 6 and Figure 16-18 As shown, a second rotor pump 756 is connected to the bottom end of the phospholipid guide tube 737. A first mounting plate 757 is fixedly installed at the bottom of the second rotor pump 756 to facilitate its installation. The first mounting plate 757 is fixedly installed at the bottom of the conical sleeve 722. A second reducer 758 is fixedly installed at the middle of the bottom end of the conical sleeve 722. A fifth drive motor 759 is connected to the input end of the second reducer 758. A second reducer 758 and a fifth drive motor 759 are fixedly installed at their bottoms. Mounting plate 760 is fixedly mounted on the falling film evaporator 501. A second drive motor 503 for driving the rotating scraper 502 is located at the bottom of the second mounting plate 760. Multiple transfer pipes 761, cooperating with the second rotor pump 756, are located at the top of the falling film evaporator 501. These transfer pipes 761 are movably engaged at the top of the falling film evaporator 501. Multiple third compression springs 762 are mounted on the transfer pipes 761, with each end of the third compression spring 762 respectively connected to… The outer edge of the transfer pipe 2 761 abuts against the top wall of the falling film evaporator 501. A sealing block 2 763 is provided on one side of the transfer pipe 2 761 to seal it. A guide slider 2 764 is fixedly installed on one side of the sealing block 2 763. A connecting rod 2 765 is fixedly installed on one side of the guide slider 2 764. One end of the connecting rod 2 765 is fixedly connected to a third rotating shaft 766. The falling film evaporator 501 has openings to facilitate the installation of the guide slider 2 764, the connecting rod 2 765, and the third rotating shaft 766. Mounting groove 2 767, guide slider 2 764 and connecting rod 2 765 are all slidably locked in mounting groove 2 767 with the third rotating shaft 766 as the center. The guide slider 2 764 is located in a section inside mounting groove 2 767, and arc springs 2 768 are fixedly abutted on both sides of it. The two ends of the arc springs 2 768 are fixedly connected to the guide slider 2 764 and the inner wall of mounting groove 2 767, respectively.

[0107] It should be noted that the outer edge of the top of the transfer tube 761 is tapered, narrower at the top and wider at the bottom, to cooperate with the multiple third compression springs 762 fixedly connected to its bottom. This allows the transfer tube 761 to gradually compress the third compression springs 762 under the pressure of the output end of the second rotor pump 756 and the sealing block 763, causing it to contract. This ensures that the transfer tube 761 remains contracted within the falling film evaporator 501 until it is flush with the top of the falling film evaporator 501. At this point, the transfer tube 761, under the action of the third compression springs 762, will always abut against the output end of the second rotor pump 756 or the sealing block 763, ensuring that the transfer tube 761 is in contact with the output end of the second rotor pump 756 and the sealing block 763. The 63 sections have good sealing properties to prevent hydrated phospholipid from flowing out of the gap between the output end of the second rotor pump 756 and the intermediate transfer pipe 761 during transportation, or to prevent water vapor generated by the operation of the falling film evaporator 5 from flowing into the falling film evaporator 501 through the gap between the intermediate transfer pipe 761 and the sealing block 763, so that the falling film evaporator 501 can maintain good sealing. In addition, when the top of the intermediate transfer pipe 761 is flush with the top of the falling film evaporator 501, its bottom end is lower than the bottom plane of the top of the falling film evaporator 501, thereby preventing the hydrated phospholipid flowing through the intermediate transfer pipe 761 from flowing into the groove where the third compression spring 762 is installed through the bottom end of the intermediate transfer pipe 761, effectively ensuring the utilization rate of resources.

[0108] On the other hand, the cross-sectional dimension of the sealing block 763 is larger than that of the transfer pipe 761, so that the sealing block 763 can fit perfectly against the surface of the transfer pipe 761 to seal it. This prevents water vapor generated during the operation of the falling film evaporation section 5 from flowing into the falling film evaporator 501 through the gap between the sealing block 763 and the transfer pipe 761, thus preventing water vapor from combining with the hydrated phospholipid and further controlling the water content inside the hydrated phospholipid, effectively ensuring the purity of the hydrated phospholipid. When the arc spring 768 is in its free state, the extension degree of the guide slider 764 is located at the middle of the outer edge of the mounting groove 767. At this time, the sealing block 763 fixedly connected to the guide slider 764 fits against the surface of the transfer pipe 761 to seal it. When the guide slider 2 764 is squeezed by the output end of the second rotor pump 756, the arc springs 2 768 on both sides of the guide slider 2 764 are subjected to compression and tension forces respectively, causing the guide slider 2 764 to slide inside the mounting groove 2 767 with the third rotating shaft 766 as the center, and driving the sealing block 2 763 to disengage from the transfer pipe 2 761, so that the output end of the second rotor pump 756 covers the transfer pipe 2 761, so as to transport the hydrated phospholipid to the settling module 702 for settling. Moreover, the elastic force of the arc spring 2 768 is greater than the elastic force of the third compression spring 762, so that when the sealing block 2 763 resets, it squeezes the transfer pipe 2 761, causing it to retract into the falling film evaporator 501 and abut against the bottom wall of the sealing block 2 763.

[0109] In this embodiment, the hydrated phospholipids separated by centrifugation flow into the solution settling box 718 in the solution settling tank 701 for settling and stratification. The hydrated phospholipids are separated into three layers in the solution settling box 718: neutral oil, hydrated phospholipids, water, and water-soluble impurities. The layers are discharged and collected through the first liquid recovery pipe 735 and the second liquid recovery pipe 736, making full use of the resources. At the same time, since the hydrated phospholipids obtained after settling contain only a small amount of neutral oil, water, and water-soluble impurities, they are less likely to cause blockage and corrosion of the falling film evaporator tube wall during the falling film evaporation process.

[0110] During use, the hydrated phospholipids separated by centrifuge 401 are discharged into the solution transfer tank 403. The third drive motor 708 is then activated, driving the first reducer 707 to rotate, causing the turntable 704 to rotate clockwise at the bottom of the solution transfer tank 403. This rotation also drives the first rotor pump 709, fixed on the turntable 704, to rotate clockwise. During this process, the output end of the first rotor pump 709 gradually compresses the first transfer tube 710, causing the transfer tube 710 to apply pressure to the first compression spring 711, keeping the transfer tube 710 confined within the solution settling tank 701 until it is flush with the top of the solution settling tank 701. Simultaneously, the output end of the first rotor pump 709 also compresses the transfer tube 710. The sealing block 712 on 710 is compressed, and the guide slider 713 fixed on the sealing block 712 will compress and stretch the arc springs 717 on both sides accordingly. This causes the guide slider 713 to slide inside the mounting groove 716 with the first rotating shaft 715 as the center, and drive the sealing block 712 to disengage from the transfer pipe 710. This allows the output end of the first rotor pump 709 to cover the transfer pipe 710. At this time, the third drive motor 708 stops, and the transfer pipe 710 will always be in contact with the output end of the first rotor pump 709 under the action of the first compression spring 711. Then, the first rotor pump 709 is started. The first rotor pump 709 has a preset threshold value, so that the first discharge... The total amount of hydrated phospholipid will not exceed the actual volume of the solution settling box 718. The hydrated phospholipid in the solution transfer tank 403 is transported to the solution settling box 718 corresponding to the transfer tube 710. When the solution settling box 718 is gradually filled with hydrated phospholipid, the first rotor pump 709 is stopped, and then the third drive motor 708 is restarted, causing the first reducer 707 to drive the turntable 704 to rotate clockwise at the bottom of the solution transfer tank 403. During this process, the output end of the first rotor pump 709 gradually disengages from the transfer tube 710, and the transfer tube 710 will be ejected from the solution settling box 701 under the action of the first compression spring 711. When the output end of the first rotor pump 709 is completely separated from the sealing block... After block 712 is disengaged, it will be reset by the action of arc spring 717 and squeeze transfer tube 710, causing it to retract back into solution settling tank 701. When the output end of the first rotor pump 709 driven by turntable 704 is covered on the next transfer tube 710, the third drive motor 708 stops and the first rotor pump 709 starts to deliver hydrated phospholipid. This operation is repeated until the output end of the first rotor pump 709 covers the last transfer tube 710 for delivery. Then the third drive motor 708 starts again and drives turntable 704 to rotate counterclockwise, so that the first rotor pump 709 rotates to the initial position and the third drive motor 708 stops.

[0111] After the hydrated phospholipids in the solution settling box 718 have completely settled and separated, the fifth drive motor 759 is started, driving the second reducer 758 to rotate, so that the conical sleeve 722 rotates clockwise at the bottom of the solution settling box 701, and drives the second rotor pump 756 fixed on the conical sleeve 722 to rotate clockwise. During this process, the output end of the second rotor pump 756 gradually squeezes the first intermediate transfer tube 761, so that the intermediate transfer tube 761 applies pressure to the third compression spring 762, and keeps the intermediate transfer tube 761 contracted inside the falling film evaporator 501 until it is flush with the top of the falling film evaporator 501. At the same time, the output end of the second rotor pump 756 also presses the sealing block 720 covering the intermediate transfer tube 761. When 63 is compressed, the guide slider 764 fixed on the sealing block 763 will compress and stretch the arc springs 768 on both sides, causing the guide slider 764 to slide inside the mounting groove 767 with the third rotating shaft 766 as the center. This will cause the sealing block 763 to disengage from the transfer pipe 761, so that the output end of the second rotor pump 756 covers the transfer pipe 761. At this time, the fifth drive motor 759 stops, and the transfer pipe 761 will always be in contact with the output end of the second rotor pump 756 under the action of the third compression spring 762. Then, the airbag compression assembly 723 set on the conical sleeve 722 is activated, causing the airbags set on both sides of the partition baffle 720 to expand and divide the... The baffles 720 are pressed together, causing the baffles 720, which are slidably mounted on both sides of the solution settling box 718, to gradually move closer to the solution settling box 718 and abut against each other, dividing the solution settling box 718 into three chambers. This completely separates the neutral oil, hydrated phospholipids, water, and water-soluble impurities that have settled and separated within the solution settling box 718. Then, the fourth drive motor 753 is activated to drive the second rotating shaft 752 to rotate, which in turn drives the gear 754 on the second rotating shaft 752 to rotate. Then, through the toothed belt 755 sleeved on the outside of the gear 754, the three second rotating shafts 752 are driven to rotate synchronously, so that the second rotating shafts 752 are connected to the second synchronous pulley 751 fixed in the middle. A synchronous belt 750, externally sleeved on pulley 751, drives the first synchronous pulley 749 to rotate. This causes the first synchronous pulley 749 to drive the first adjusting screw 742 and the second adjusting screw 748 to rotate within the tapered sleeve 722. This causes the first guide block 741 and the second guide block 747, threadedly connected to the first adjusting screw 742 and the second adjusting screw 748, to cause the first telescopic tube 740 and the second telescopic tube 746, fixedly connected to their bottoms, to extend and retract respectively on the first fixed tube 739 and the second fixed tube 745. This allows the first telescopic tube 740 to insert into the drain pipe 719, and the second telescopic tube 746 to insert into the first liquid recovery pipe 735, the second liquid recovery pipe 736, and the drain pipe 719.Then, the ball valves on the corresponding drain pipe 719, the first liquid recovery pipe 735, and the second liquid recovery pipe 736 are opened, allowing the neutral oil, water, and water-soluble impurities that have separated in the solution settling box 718 to flow into the recovery device through the first liquid recovery pipe 735 and the second liquid recovery pipe 736, respectively.

[0112] Then, the second rotor pump 756 is started to transport the hydrated phospholipid in the solution settling box 718 to the falling film evaporator 501. After the hydrated phospholipid in the solution settling box 718 is completely extracted, the second rotor pump 756 is stopped, and the above operation is repeated until all the hydrated phospholipid in the last solution settling box 718 is extracted and transported to the falling film evaporator 501. Then, the fifth drive motor 759 is started again and drives the conical sleeve 722 to rotate counterclockwise, so that the second rotor pump 756 rotates to the initial position and the fifth drive motor 759 stops.

[0113] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
