Description

Technical Field

[0001] The present invention relates to the technical field of powder phospholipid production, and more specifically, to a production device for soybean phospholipid oil powder based on microcapsule technology. Background Art

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

[0003] Since soybean phospholipid oil powder is rich in unsaturated fatty acids, it will undergo auto-oxidation with oxygen when exposed to air, generating harmful substances such as peroxides and aldehydes. Therefore, packaging and sealing after production is an important step to ensure its quality stability, extend the shelf life, prevent oxidation and moisture absorption. Currently, common preservation methods for soybean phospholipid oil powder include vacuum aluminum foil bag packaging, PET / PE composite bag packaging, tinplate barrel packaging and microcapsule technology packaging, etc.

[0004] Among them, microcapsule technology usually makes soybean phospholipid oil powder into capsules to physically isolate the contact between soybean phospholipid oil powder and air and moisture, keep the phospholipids inside the soybean phospholipid oil powder stable, and effectively extend the shelf life of soybean phospholipid oil powder. Therefore, microcapsule technology has high practical value for preserving soybean phospholipid oil powder.

[0005] Currently, when the industrial use of microcapsule technology to preserve soybean phospholipid oil powder, the soybean phospholipid oil powder is required to have a high purity. However, the soybean phospholipid oil powder obtained by the existing production devices for soybean phospholipid oil powder has a low purity and is rich in excessive neutral lipids, proteins, sugars and metal ions inside, which affects the formation of a uniform microcapsule membrane on the surface of soybean phospholipids, resulting in an incomplete microcapsule membrane. Therefore, before using microcapsule technology to preserve soybean phospholipid oil powder, the soybean phospholipid oil powder is usually purified first.

[0006] Common purification methods in the prior art include solvent fractional extraction method, supercritical CO2 extraction method and short-path molecular distillation method.

[0007] The solvent fractional extraction method usually uses an acidic solution as an extractant for hydrating and degumming crude soybean oil, such as hydrochloric acid, citric acid, acetic acid, etc. The introduction of acidic conditions can enhance the ability to selectively separate phospholipids, thereby improving the purity of soybean phospholipid oil powder. However, after the introduction of acidic conditions, it is necessary to stop the machine for distilling and recovering the solvent, and the equipment needs to be thoroughly cleaned between different batches to avoid cross-contamination. Therefore, continuous production cannot be achieved by the purification work through the solvent fractional extraction method.

[0008] The supercritical CO2 extraction method is a green separation technology that uses the high permeability and selective dissolution ability of CO2 in the supercritical state to purify phospholipids. However, the investment and maintenance costs of high-pressure equipment are high, the seals are vulnerable and need to be replaced frequently, and after each batch is completed, it is necessary to release pressure safely. Re-pressurization and temperature equilibration take a long time, resulting in the inability to achieve continuous feeding and discharging of materials, and only intermittent operation is possible.

[0009] The short-path molecular distillation method separates low-boiling components in phospholipids under high-vacuum conditions and is suitable for the purification of heat-sensitive substances. However, the high-molecular polymers or cokes remaining after distillation of hydrated phospholipids will adhere to the surface of the evaporator and need to be cleaned regularly, so it cannot operate continuously completely. Summary of the Invention

[0010] The object of the present invention is to provide a soybean phospholipid oil powder production device based on microcapsule technology to improve the continuous operation ability 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 solutions.

[0012] A soybean phospholipid oil powder production device based on microcapsule technology, including a tank body, characterized in that a hydration degumming part, an acid-base neutralization part, a centrifugation part, a falling film evaporation part and a short-path distillation part are sequentially arranged in the tank body from top to bottom. A conical tank for installing the hydration degumming part and the acid-base neutralization part is fixedly arranged at the top of the tank body. A condensate recovery cylinder is fixedly arranged at the bottom side of the conical tank. The water vapor generated by the falling film evaporation part rises freely inside the tank body and heats the hydration degumming part and the acid-base neutralization part arranged in the conical tank. The condensate recovery cylinder is used to collect the condensate condensed on the outer wall of the conical cylinder and is used to clean the centrifugation part. A solenoid valve for discharging the condensate is arranged at the bottom of the condensate recovery cylinder. The output end of the solenoid valve is fixedly connected to a water delivery pipe communicated with the centrifugation part. A waste water discharge pipe for discharging waste water is arranged on the centrifugation part.

[0013] The prior art generally adopts the method of jacket heating, that is, a jacket is arranged on the outer wall of the reaction tank and hot water is introduced to make the tank wall of the reaction tank uniformly heated, so as to improve the reaction efficiency when crude soybean oil undergoes hydration degumming and acid-base neutralization reactions. Although the method of jacket heating can effectively improve the reaction efficiency when crude soybean oil undergoes hydration degumming and acid-base neutralization reactions, the hot water in the heating jacket consumes a lot of energy.

[0014] In the present invention, the hot vapor generated during the operation of the falling film evaporation part is used to heat the hydration degumming part, the acid-base neutralization part and the centrifugation part, which improves the efficiency of hydration degumming reaction, acid-base neutralization reaction and centrifugal separation while reducing energy consumption.

[0015] Optionally, the following are provided inside the conical tank: A first partition plate, which is fixedly arranged inside the conical tank and divides the conical tank into a hydration degumming chamber and an acid-base neutralization chamber; A first liquid inlet pipe: It is arranged on the top end of the tank body and penetrates through the tank body to communicate with the hydration degumming chamber, and is used for pouring an acidic solution into the hydration degumming chamber; A second liquid inlet pipe: It is arranged on one side of the tank body and penetrates through the tank body to communicate with the acid-base neutralization chamber, and is used for pouring an alkaline solution into the acid-base neutralization chamber; A stirring rod: It is rotatably arranged inside the conical tank and is used for stirring the soybean crude oil, acidic solution and alkaline solution placed inside the conical tank; A thrust balance plate: It is fixedly arranged inside the acid-base neutralization chamber and is used for restricting the bottom position of the stirring rod and reducing the centripetal force when the stirring rod rotates; A first driving motor: It is fixedly arranged on the top end of the tank body to drive the stirring rod; A first propeller blade: It is fixedly arranged on a section of the stirring rod close to the top end of the first partition plate and is used for conveying the solution inside the hydration degumming chamber; A second propeller blade, which is fixedly arranged on a section of the stirring rod close to the top end of the thrust balance plate and is used for conveying the solution inside the acid-base neutralization chamber A first ball valve: It is fixedly arranged at the bottom of the first partition plate and is used for controlling the inflow and outflow of the phospholipid mixed solution inside the hydration degumming chamber; A second ball valve: It is fixedly arranged at the bottom of the conical tank and is used for controlling the inflow and outflow of the leaching juice mixed solution inside the acid-base neutralization chamber; An infusion pipe: It is fixedly arranged at the output end of the second ball valve and communicates with the centrifugal part, and is used for conveying the phospholipid mixed solution inside the acid-base neutralization chamber to the centrifugal part for centrifugal separation.

[0016] Optionally, the centrifugal part includes: A centrifuge: It is arranged at the bottom of the conical tank and is used for centrifugally separating the input phospholipid mixed solution; A support seat: It is fixedly arranged at the bottom of the centrifuge to provide support for the centrifuge; A solution transfer tank: It is arranged at the bottom of the support seat, and a plurality of connecting support rods are circumferentially distributed at the outer edge of the solution transfer tank. The solution transfer tank is fixedly arranged inside the tank body through the connecting support rods and collects the hydrated phospholipids generated after the phospholipid mixed solution passes through centrifugal separation by the centrifuge; A phospholipid delivery pipe: It is fixedly arranged at the bottom of the solution transfer tank and communicates with the falling film evaporation part; Recovery Pipe 1: It is arranged on one side close to the top of the centrifuge and is used to recover the degummed soybean oil after centrifugal separation; Phospholipid Delivery Pipe: It is arranged on one side close to the middle of the centrifuge and is used to deliver the hydrated phospholipids after centrifugal separation; Recovery Pipe 2: It is arranged on one side close to the bottom of the centrifuge and is used to recover the neutralization waste liquid after centrifugal separation; Ball Valve 3: It is fixedly arranged at the liquid inlet ends of the phospholipid delivery pipe, the first recovery pipe, the phospholipid delivery pipe and the second recovery pipe, and is used to control the inflow and outflow of the solution after centrifugal separation.

[0017] In the prior art, after the phospholipid mixture undergoes an acid-base neutralization reaction and is centrifugally separated in the centrifuge, there will still be a small amount of residues of hydrated phospholipids and degummed soybean oil adhering to the inner wall of the centrifuge. After the centrifuge centrifugally separates multiple groups of phospholipid mixtures, the hydrated phospholipids and degummed soybean oil adhering to the inner wall of the centrifuge will gradually increase. If not cleaned in time, it will affect the separation quality of the subsequent phospholipid mixture during centrifugal separation in the centrifuge. If the centrifuge is shut down to clean the hydrated phospholipids and degummed soybean oil adhering to the inner wall, it is not conducive to the continuous production of crude soybean oil.

[0018] In the present invention, while using the vapor discharged from the falling film evaporation section to heat the conical tank, the vapor will condense on the outer wall of the conical tank to form condensed water, and then flow into the condensed water recovery cylinder for storage. Since the centrifugal separation of the phospholipid mixture only takes 10 - 30 seconds, when the centrifuge centrifugally separates a batch of phospholipid mixtures, the phospholipid mixtures in the hydrated degumming section, acid-base neutralization section, falling film evaporation section and short path distillation section are still being processed, and the centrifuge is idle for a relatively long time. When the centrifuge is idle, only need to control the solenoid valve to open, so that the condensed water in the condensed water recovery cylinder flows into the centrifuge, and then start the centrifuge, so that the condensed water cleans the centrifuge, and flows through the waste water discharge pipe on the centrifuge into the waste water recovery device set outside for recovery, thus eliminating the need to shut down the centrifuge for cleaning.

[0019] Optionally, the short path distillation section includes: Short Path Distiller: It is fixedly arranged in the tank body and improves the purity of hydrated phospholipids through the difference in molecular mean free path; Phospholipid Discharge Pipe: It is opened at the bottom of the short path distiller and extends through the tank body to the outside to deliver the purified hydrated phospholipids; Hydrated Phospholipid Transfer Tank: It is fixedly arranged at the top of the short path distiller, collects the hydrated phospholipids discharged from the falling film tube, and discharges the hydrated phospholipids into the short path distiller for subsequent processing.

[0020] In the prior art, the hydrated phospholipids obtained by centrifugal separation are rich in neutral oil, hydrated phospholipids, water and water-soluble impurities inside. If film falling evaporation is directly carried out on them, the sugars rich in the water-soluble impurities will caramelize at high temperature to form brown solids adhering to the tube wall of the film falling evaporator. Prolonged use will cause blockage of the film falling tube. The saponins rich in the water-soluble impurities will decompose into fatty acids and alkalis at high temperature, resulting in unnecessary corrosion of the film falling tube. On the other hand, the neutral oil rich in the hydrated phospholipids can be reprocessed into crude oil, biodiesel raw materials, industrial-grade grease, phospholipid supplements, etc. The water and water-soluble impurities rich in the hydrated phospholipids can be used for phospholipid recovery, water reuse, fermentation medium and agricultural irrigation, etc. Directly carrying out film falling evaporation on the hydrated phospholipids will cause unnecessary waste of resources.

[0021] In the present invention, the hydrated phospholipids discharged into the solution static box are statically layered inside the solution static box, so that the hydrated phospholipids in the solution static box are divided into three layers, namely neutral oil, hydrated phospholipids and water and water-soluble impurities, and are discharged and collected through the first liquid recovery pipe and the second liquid recovery pipe, making full use of resources. At the same time, since the hydrated phospholipids obtained by static settlement only contain a small amount of neutral oil and water and water-soluble impurities, it is not easy to cause blockage and corrosion of the tube wall of the film falling evaporator during the film falling evaporation process.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the present invention, the hydration degumming part and the acid-base neutralization part are arranged in the conical tank, and the hot steam generated by the operation of the falling film evaporation part is used to heat the mixed solution undergoing reaction in the hydration degumming part and the acid-base neutralization part, so as to improve the efficiency of the hydration degumming reaction, the acid-base neutralization reaction and the centrifugal separation while reducing the energy and resource consumption.

[0028] 2.

When the centrifuge is in an idle state, the solenoid valve is opened to convey the condensate into the centrifuge through the water delivery pipe, and the centrifuge is started to clean the condensate inside the centrifuge, so that the hydrated phospholipids and degummed soybean oil attached to the inner wall of the centrifuge fall off from the inner wall of the centrifuge and flow into the wastewater recovery device through the wastewater discharge pipe arranged on the centrifuge, thereby completing the cleaning of the inside of the centrifuge on the premise of keeping the equipment running normally, and effectively ensuring the continuous operation ability of the equipment.

[0029] 3.

The neutral oil, water and water-soluble impurities are discharged and collected through the first liquid recovery pipe and the second liquid recovery pipe, so as to make full use of resources. At the same time, since the hydrated phospholipids obtained by static settlement only contain a small amount of neutral oil, water and water-soluble impurities, it is not easy to cause blockage and corrosion of the wall of the falling film evaporator during the falling film evaporation process. Therefore, it is not necessary to frequently stop the equipment to clean the caramelized solids attached to the wall of the falling film evaporator, further improving the continuous operation ability of the equipment.

[0037] The embodiments of the present invention are intended to introduce and illustrate the structural composition of a gear processing device and the matching relationship between the various components. Unless otherwise specified, the dimensions, materials, and manufacturing processes of the various components suitable for the gear processing device in the embodiments of the present invention can be selected according to specific circumstances and are not specifically limited or explained here.

[0038] Furthermore, in order to provide the public with a better understanding of the present invention, some specific details are described in detail in the following detailed description of the present invention, but those skilled in the art can fully understand the present invention without the description of these details.

[0039] Example 1 The present invention provides a soybean lecithin oil powder production device based on microcapsule technology, such as Figures 1-3 As shown, it comprises a tank body 1, in which a hydration degumming section 2, an acid-base neutralization section 3, a centrifugal section 4, a falling film evaporation section 5 and a short-path distillation section 6 are sequentially arranged from top to bottom; A conical tank 8 is fixedly arranged at the top end of the tank body 1. A condensate water recovery cylinder 9 is fixedly arranged at the bottom side of the conical tank 8. A solenoid valve 10 for discharging condensate water is arranged at the bottom of the condensate water recovery cylinder 9. The output end of the solenoid valve 10 is fixedly connected to a water delivery pipe 11 communicating with the centrifugal part 4. A waste water discharge pipe 12 for discharging waste water is arranged on the centrifugal part 4. A first partition plate 13 is fixedly arranged inside the conical tank 8. The first partition plate 13 divides the conical tank 8 into a hydration degumming cavity 14 and an acid-base neutralization cavity 15. The hydration degumming part 2 and the acid-base neutralization part 3 are respectively arranged in the hydration degumming cavity 14 and the acid-base neutralization cavity 15. A first liquid inlet pipe 16 and a second liquid inlet pipe 17 are respectively arranged on the tank body 1. The first liquid inlet pipe 16 is fixedly arranged at the top end of the tank body 1 and penetrates through the tank body 1 to communicate with the hydration degumming cavity 14. The second liquid inlet pipe 17 is fixedly arranged on one side of the tank body 1 and penetrates through the tank body 1 to communicate with the acid-base neutralization cavity 15. A stirring rod 18 is rotatably arranged inside the conical tank 8. A thrust balance disk 19 is fixedly arranged on one side of the acid-base neutralization cavity 15 away from the first partition plate 13. One end of the stirring rod 18 away from the thrust balance disk 19 penetrates through the tank body 1 and is connected to a first driving motor 20. The other end of the stirring rod 18 penetrates through the first partition plate 13 and is rotatably connected to the thrust balance disk 19. The stirring rod 18, the conical tank 8, the first partition plate 13 and the thrust balance disk 19 are all coaxially arranged. A first propeller blade 21 is fixedly arranged on a section of the stirring rod 18 close to the top end of the first partition plate 13. A second propeller blade 22 is fixedly arranged on one side of the stirring rod 18 close to the top end of the thrust balance disk 19. A ball valve 23 is arranged at the bottom of the first partition plate 13. A ball valve 24 is fixedly arranged at the bottom of the conical tank 8. The output end of the ball valve 24 is fixedly connected to an infusion pipe 25. A waste water discharge pipe 12 for discharging waste water is arranged on the centrifugal part 4; It should be noted that when not in use, the liquid inlet can be sealed by an end cover threadedly connected to its top end to prevent external dust or impurities from flowing into the hydration degumming cavity 14 and the acid-base neutralization cavity 15 through the liquid inlet. Moreover, the actual volume of the acid-base neutralization cavity 15 is larger than that of the hydration degumming cavity 14, and the liquid outlet end of the liquid inlet communicating with the acid-base neutralization cavity 15 is at the top of the acid-base neutralization cavity 15, so that after the phospholipid mixture in the hydration degumming cavity 14 is discharged into the acid-base neutralization cavity 15, its liquid level is lower than the height of the output end of the liquid inlet, to prevent the phospholipid mixture in the acid-base neutralization cavity 15 from flowing into the liquid inlet during the acid-base neutralization process and ensure the stable operation of the device. On the other hand, during the hydration degumming process of crude soybean oil, adding an acidic solution can effectively increase the precipitation rate of phospholipids in the crude soybean oil, thereby improving the purity of the soybean phospholipid powder produced; On the other hand, the end of the wastewater discharge pipe 12 far from the centrifuge 401 penetrates through the tank body 1 and is connected to the external wastewater recovery device. When cleaning the impurities attached to the centrifuge 401, the vapor discharged from the falling film evaporation section 5 will heat the conical tank 8, and condense to form condensate on the outer wall of the conical tank 8, and then flow into the condensate recovery cylinder 9 for storage. When the centrifuge 401 finishes working, only need 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, so that the condensate cleans the centrifuge 401, and flows into the externally arranged wastewater recovery device through the wastewater discharge pipe 12 arranged on the centrifuge 401 for recovery. Thus, there is no need to stop the machine to clean the centrifuge 401. Only when the centrifuge 401 is idle, use the condensate collected in the condensate recovery cylinder 9 to clean the centrifuge 401, which effectively ensures the continuous operation ability of the centrifugal section 4.

[0040] Refer to Figures 2-3 As shown, the centrifugal section includes a centrifuge 401 arranged at the bottom of the conical tank 8. The centrifuge 401 is provided with a first recovery pipe 404 for recovering the centrifugally separated solution, a phospholipid delivery pipe 405 and a second recovery pipe 406. The first recovery pipe 404 is fixedly arranged on one side close to the top end of the centrifuge 401, the phospholipid delivery pipe 405 is fixedly arranged on one side close to the middle of the centrifuge 401, and the second recovery pipe 406 is fixedly arranged on one side close to the bottom end of the centrifuge 401. Both the first recovery pipe 404 and the second recovery pipe 406 penetrate through the tank body 1 and extend to the outside. The phospholipid delivery pipe 405 penetrates through the support seat 402 and is connected to the solution transfer tank 403. Ball valves 407 are fixedly arranged at the liquid inlet ends of the first recovery pipe 404, the phospholipid delivery pipe 405 and the second recovery pipe 406. A support seat 402 for supporting the centrifuge 401 is fixedly arranged at the bottom of the centrifuge 401. A solution transfer tank 403 is fixedly arranged at the bottom of the support seat 402. A plurality of connecting support rods 409 are circumferentially arranged at the outer edge of the solution transfer tank 403. The solution transfer tank 403 is fixedly arranged in the tank body 1 through the connecting support rods 409. A phospholipid delivery pipe 410 for delivering the phospholipid mixture is arranged at the bottom of the solution transfer tank 403.

[0041] It should be noted that in this embodiment, the centrifuge 401 is a three-phase disc centrifuge 401, which centrifugally separates the phospholipid mixture entering the interior of the three-phase disc centrifuge 401 into light-phase degummed soybean oil, middle-phase hydrated phospholipids, and heavy-phase neutralization waste liquid. Recovery devices are respectively connected to the recovery pipes at the top and bottom of the three-phase disc centrifuge 401 to recover the degummed soybean oil and neutralization waste liquid. The degummed soybean oil collected in the recovery device can be used for direct industrial use, food-grade reuse, agriculture and feed fields, and high-value-added utilization, etc. The neutralization waste liquid collected in the recovery device can be detected. If its pH value, COD content, phosphate content, and oil content all meet the discharge standards, the neutralization waste liquid can be directly discharged. If any one of the pH value, COD content, phosphate content, and oil content in the neutralization waste liquid does not meet the direct discharge standard, the neutralization waste liquid needs to be treated accordingly before it can be discharged to reduce damage to the natural environment. The recovery pipe in the middle of the centrifuge 401 transports the hydrated phospholipids in the three-phase disc centrifuge 401 to the solution transfer tank 403 for subsequent processing.

[0042] Referring to Figure 3 As shown, the falling film evaporation section 5 includes a falling film evaporation tank 501 provided at the bottom of the conical sleeve 722. A rotary scraper 502 is rotatably provided on the falling film evaporation tank 501. A second drive motor 503 for driving the rotary scraper 502 is provided at the top of the falling film evaporation tank 501. A second partition plate 504 is fixedly provided inside the falling film evaporation tank 501. The second partition plate 504 divides the falling film evaporation tank 501 into a scraping film chamber 505 and a heating chamber 506. A plurality of falling film tubes 508 are provided inside the heating chamber 506. The top ends of the falling film tubes 508 penetrate through the second partition plate 504 and communicate with the scraping film chamber 505. An external heat source 507 for heating it is connected to the heating chamber 506. A plurality of steam discharge holes 509 for facilitating the outflow of steam are provided at the bottom side of the heating chamber 506. The short path distillation section 6 includes a short path distiller 601 fixedly provided at the bottom of the falling film evaporation tank 501. The short path distiller 601 is fixedly provided inside the tank body 1. A phospholipid discharge pipe 602 penetrating through the bottom of the tank body 1 is provided at the bottom of the short path distiller 601. A hydrated phospholipid transfer tank 603 for collecting hydrated phospholipids is fixedly provided at the top of the short path distiller 601. The top end of the hydrated phospholipid transfer tank 603 is communicated with a plurality of falling film tubes 508. A...

[0043] It should be noted that a ball valve communicating with the liquid inlet end of the short path distiller 601 is provided at the bottom liquid discharge end of the hydrated phospholipid transfer tank 603 to control whether the hydrated phospholipids in the hydrated phospholipid transfer tank 603 flow into the short path distiller 601 and control the flow rate of the flowing hydrated phospholipids; During use, pour crude soybean oil into the conical tank 8 along the first liquid inlet pipe 16 opened on the tank body 1. Then, pour the acidic solution along the liquid inlet according to the total amount of the poured crude soybean oil. Then, control the first drive motor 20 to start and drive the stirring rod 18 to rotate in the hydration degumming chamber 14 and the acid-base neutralization chamber 15. When the hydration degumming reaction of the crude soybean oil is completed, the first ball valve 23 is opened, and the first propeller blade 21 arranged on the stirring rod 18 will, under the rotation of the stirring rod 18, convey the phospholipid mixed solution in the hydration degumming chamber 14, so that it flows into the acid-base neutralization chamber 15 through the first ball valve 23. After the phospholipid mixed solution in the hydration degumming chamber 14 completely flows into the acid-base neutralization chamber 15, the first drive motor 20 stops, and the first ball valve 23 closes. At this time, pour crude soybean oil and an appropriate amount of acidic solution into the hydration degumming chamber 14 again along the first liquid inlet pipe 16 opened on the tank body 1, and pour an appropriate amount of alkaline solution into the acid-base neutralization chamber 15 along the second liquid inlet pipe 17 to cause a neutralization reaction with the acidic solution in the phospholipid mixed solution to balance the pH value of the phospholipid mixed solution. Then, start the first drive motor 20 again to drive the stirring rod 18 to rotate in the hydration degumming chamber 14 and the acid-base neutralization chamber 15 to increase the reaction rate of the hydration degumming reaction and the acid-base neutralization reaction. When the acid-base neutralization reaction of the phospholipid mixed solution is completed, the second ball valve 24 is opened, and the second propeller blade 22 arranged on the stirring rod 18 will, under the rotation of the stirring rod 18, convey the phospholipid mixed solution in the acid-base neutralization chamber 15, so that it flows into the centrifuge 401 through the second ball valve 24 and the infusion pipe 25 for centrifugal separation. Since the single-pass time for centrifugal separation of the phospholipid mixed solution is only 10 - 30 seconds, during the process of conveying the phospholipid mixed solution in the acid-base neutralization chamber 15 to the centrifuge 401 for centrifugal separation, the stirring and conveying of the phospholipid mixed solution by the stirring rod 18 and the first propeller blade 21 will not affect the acid-base neutralization effect of the phospholipid mixed solution in the acid-base neutralization chamber 15. After all the phospholipid mixed solution in the acid-base neutralization chamber 15 is conveyed to the centrifuge 401 for centrifugal separation, the first ball valve 23 is opened, and the phospholipid mixed solution in the hydration degumming chamber 14 flows into the acid-base neutralization chamber 15 under the conveyance of the first propeller blade 21. Then, the first drive motor 20 stops, and the first ball valve 23 closes. Pour crude soybean oil and an appropriate amount of acidic solution into the hydration degumming chamber 14 again along the first liquid inlet pipe 16 opened on the tank body 1, and pour an appropriate amount of alkaline solution into the acid-base neutralization chamber 15 along the second liquid inlet pipe 17. Then, control the first drive motor 20 to start and drive the stirring rod 18 to rotate in the hydration degumming chamber 14 and the acid-base neutralization chamber 15 to increase the reaction rate of the hydration degumming reaction and the acid-base neutralization reaction. During this process, the centrifuged phospholipid mixed solution in the centrifuge 401 is divided into three layers. The upper layer is degummed soybean oil, the middle layer is hydrated phospholipid, and the lower layer is neutralization waste liquid. The upper-layer degummed soybean oil flows into the externally provided recovery device through the third ball valve 407 and the first recovery pipe 404, and the lower-layer neutralization waste liquid flows into the externally provided recovery device through the third ball valve 407 and the second recovery pipe 406.The hydrated phospholipids in the middle layer flow into the solution transfer tank 403 through the ball valve three 407 and the phospholipid delivery pipe 405, and then flow into the falling film evaporation tank 501 through the phospholipid delivery pipe 410 arranged at the bottom of the solution transfer tank 403 for falling film evaporation to further purify the phospholipid mixture. During the process of falling film evaporation and purification, the hot steam discharged by the external heat source 507 into the heating chamber 506 will flow out of the heating chamber 506 through the steam discharge hole 509 and heat the inside of the tank body 1, so that the temperature of the phospholipid mixture processed in the hydration degumming section 2, acid-base neutralization section 3 and centrifugation section 4 increases, so as to improve the efficiency of the hydration degumming reaction, acid-base neutralization reaction and centrifugal separation. The hydrated phospholipids evaporated and purified by the falling film evaporation section 5 flow into the hydrated phospholipid transfer tank 603 through multiple falling film tubes 508 under the action of gravity, and then flow into the short-path distiller 601 through the ball valve arranged at the bottom of the hydrated phospholipid transfer tank 603 for further purification, and are discharged through the phospholipid discharge pipe 602 arranged at the bottom of the short-path distiller 601, thus completing the production and processing of soybean phospholipid powder; When cleaning the impurities attached to the centrifuge 401, the steam discharged from the falling film evaporation section 5 will heat the conical tank 8, and condense to form condensed water on the outer wall of the conical tank 8, and then flow into the condensed water recovery cylinder 9 for storage. When the centrifuge 401 finishes working, only need to control the solenoid valve 10 to open, so that the condensed water in the condensed water recovery cylinder 9 flows into the centrifuge 401, and then start the centrifuge 401, so that the condensed water cleans the centrifuge 401, and flows into the waste water recovery device set outside through the waste water discharge pipe 12 arranged on the centrifuge 401 for recovery.

[0044] Example Two This embodiment is further optimized on the basis of Example One. The hydrated phospholipids separated by the centrifuge 401 are rich in neutral oil, hydrated phospholipids, water and water-soluble impurities. If directly subjected to falling film evaporation, the free fatty acids rich in the hydrated phospholipids will oxidize to generate aldehyde and ketone harmful gases at high temperature, and the sugars rich in the water-soluble impurities will caramelize at high temperature to form brown solids attached to the tube wall of the falling film evaporator. Prolonged use will cause blockage of the falling film tubes 508. The saponins rich in the water-soluble impurities will decompose into fatty acids and alkalis at high temperature, resulting in unnecessary corrosion of the falling film tubes 508; on the other hand, the neutral oil rich in the hydrated phospholipids can be reprocessed into crude oil, biodiesel raw materials, industrial-grade oils, phospholipid supplements, etc. The water and water-soluble impurities rich in the hydrated phospholipids can be used for phospholipid recovery, water reuse, fermentation medium and agricultural irrigation, etc. Direct falling film evaporation of the hydrated phospholipids will cause unnecessary waste of resources.

[0045] Refer to Figures 3-18As shown in the figure, a static recovery part 7 is arranged between the centrifugal part 4 and the falling film evaporation part 5. The static recovery part 7 includes a solution static box 701 arranged at the bottom of the solution transfer box 403. The support base 402 is fixedly arranged at the top end of the solution static box 701. A plurality of static modules 702 facilitating the static settlement of the solution are fixedly arranged inside the solution static box 701. The bottoms of the plurality of static modules 702 are fixedly connected to a bottom plate 703. A turntable 704 is rotatably arranged at the bottom of the solution transfer box 403. A first ball group 705 is circumferentially arranged at the outer edge of the turntable 704. A first ball groove 706 matching the first ball group 705 is formed on the solution transfer box 403. The middle part of the bottom end of the turntable 704 is connected to a first speed reducer 707 and a third driving motor 708. A first rotor pump 709 facilitating the discharge of hydrated phospholipids is fixedly arranged on the turntable 704. The output end of the first rotor pump 709 is flush with the top end of the solution static box 701. A plurality of first transfer pipes 710 matching the output end of the first rotor pump 709 are arranged on the solution static box 701. The first transfer pipes 710 are movably clamped at the top end of the solution static box 701. A plurality of first compression springs 711 are arranged on the first transfer pipes 710. The two ends of the first compression springs 711 are respectively abutted against the outer edge of the first transfer pipes 710 and the top wall of the solution static box 701; On one side of the plurality of first transfer pipes 710, a first blocking block 712 for blocking them is arranged. A first guiding slider 713 is fixedly arranged at one end of the first blocking block 712 away from the first transfer pipes 710. A first connecting rod 714 is fixedly arranged at one end of the first guiding slider 713 away from the first blocking block 712. The bottom of one end of the first connecting rod 714 away from the first guiding slider 713 is fixedly connected to a first rotating shaft 715. An installation groove 716 facilitating the installation of the first guiding slider 713, the first connecting rod 714 and the first rotating shaft 715 is formed on the solution static box 701. Both ends of the first rotating shaft 715 are rotatably arranged on the inner wall of the installation groove 716. The first guiding slider 713 and the first connecting rod 714 are both slidably clamped in the installation groove 716 with the first rotating shaft 715 as the center. On a section of the first guiding slider 713 located inside the installation groove 716, arc-shaped springs 717 are fixedly abutted on both sides of it. The two ends of the arc-shaped springs 717 are respectively fixedly connected to the first guiding slider 713 and the inner wall of the installation groove 716.

[0046] It should be noted that the outer edge of the top end of the first transfer pipe 710 is designed with a tapered shape that is narrower at the top and wider at the bottom, so as to cooperate with a plurality of first compression springs 711 fixedly connected to its bottom, enabling the first transfer pipe 710 to gradually apply pressure to the first compression springs 711 under the extrusion of the output end of the first rotor pump 709 and the first plugging block 712, causing them to contract, so that the first transfer pipe 710 is always retracted into the solution static box 701 until it is flush with the top end of the solution static box 701. At this time, the first transfer pipe 710 will always abut against the output end of the first rotor pump 709 or the first plugging block 712 under the action of the first compression springs 711, so as to ensure good sealing between the first transfer pipe 710 and the output end of the first rotor pump 709 and the first plugging block 712, to prevent the hydrated phospholipids from flowing out through the gap between the output end of the first rotor pump 709 and the first transfer pipe 710 during transportation, or to prevent the water vapor generated by the operation of the falling film evaporation section 5 from flowing into the solution static box 701 through the gap between the first transfer pipe 710 and the first plugging block 712, enabling the solution static box 701 to maintain good sealing. Moreover, when the first transfer pipe 710 is in a state where its top end is flush with the top end of the solution static box 701, its bottom end is lower than the bottom plane of the top end of the solution static box 701, thus preventing the hydrated phospholipids flowing through the first transfer pipe 710 from flowing into the groove where the first compression springs 711 are installed through the bottom end of the first transfer pipe 710, effectively ensuring the resource utilization rate; On the other hand, the cross-sectional dimension of the first plugging block 712 is larger than that of the first transfer pipe 710, so that the first plugging block 712 can fit well on the surface of the first transfer pipe 710 to block it, preventing the water vapor generated by the operation of the falling film evaporation section 5 from flowing into the solution static box 701 through the fitting gap between the first plugging block 712 and the first transfer pipe 710, to avoid the combination of water vapor and hydrated phospholipids, further controlling the water content inside the hydrated phospholipids and effectively ensuring the purity of the hydrated phospholipids. The extension degree of the first arc spring 717 in the free state makes the first guiding slider 713 located in the middle of the outer edge of the first installation groove 716. At this time, the first plugging block 712 fixedly connected to the first guiding slider 713 fits on the surface of the first transfer pipe 710 to block it. When the first guiding slider 713 is extruded by the output end of the first rotor pump 709, the first arc springs 717 on both sides of the first guiding slider 713 are respectively subjected to compressive and tensile forces, causing the first guiding slider 713 to slide inside the first installation groove 716 with the first rotating shaft 715 as the center and driving the first plugging block 712 to disengage from the first transfer pipe 710, so that the output end of the first rotor pump 709 covers the first transfer pipe 710, in order to transport the hydrated phospholipids to the static module 702 for static settlement. Moreover, the elastic force of the first arc spring 717 is greater than the elastic force of the first compression spring 711, so that when the first plugging block 712 resets, it extrudes the first transfer pipe 710, causing it to retract into the solution static box 701 again and abut against the bottom wall of the first plugging block 712.

[0047] Refer to Figures 5-7 As shown in Figures 11-13 The static module 702 includes a plurality of solution static boxes 718 which are inclinedly arranged on the solution static box 701. The solution static boxes 718 are circumferentially distributed on the solution static box 701. A plurality of drain pipes 719 facilitating the discharge of the solution are provided on the solution static boxes 718. A plurality of partition baffles 720 are movably clamped inside the solution static boxes 718. The outer ends of the partition baffles 720 are abutted against second compression springs 721. The two ends of the second compression springs 721 are respectively abutted against the partition baffles 720 and the outer walls of the solution static boxes 718. A conical sleeve 722 is provided at the bottom of the solution static box 701. An airbag extrusion assembly 723 for extruding the partition baffles 720 is provided on the conical sleeve 722. The opposite ends of the plurality of partition baffles 720 are provided with plug-in ends 724 which cooperate with each other. And limiting stop strips 725 for limiting the movement positions of the partition baffles 720 are provided on the upper and lower sides of the plug-in ends 724. The plurality of partition baffles 720 divide the solution static boxes 718 into a plurality of solution storage cavities 726; A sliding block 727 is fixedly provided at the top end of the conical sleeve 722. A second ball group 728 is rotatably provided on the sliding block 727. A sliding groove 729 matching the sliding block 727 and the second ball group 728 is provided on the solution static box 701. The conical sleeve 722 is rotatably arranged at the bottom end of the solution static box 701 through the sliding block 727 and the second ball group 728. A third ball group 730 is rotatably provided at the bottom end of the bottom plate 703. A second ball groove 731 matching the third ball group 730 is provided on the conical sleeve 722. The bottom plate 703 is rotatably arranged on the conical sleeve 722 through the third ball group 730. A first waste liquid recovery box 732 and a second waste liquid recovery box 733 for recovering and storing the waste liquid are respectively provided on the solution static box 701 and the conical sleeve 722. A plurality of fixing plates 734 are circumferentially arranged on the outer side of the first waste liquid recovery box 732. The solution static box 701 is fixedly arranged in the tank body 1 through the plurality of fixing plates 734. The second waste liquid recovery box 733 is rotatably arranged on the conical sleeve 722. A plurality of first liquid recovery pipes 735 and a plurality of second liquid recovery pipes 736 are respectively provided on the first waste liquid recovery box 732 and the second waste liquid recovery box 733.

[0048] It should be noted that the airbag extrusion assembly 723 is composed of existing technologies such as an airbag and an inflation component. When it is necessary to separate the solution static box 718, only need to control the inflation component to inflate the airbag, so that the airbag squeezes the separation baffle 720, making the separation baffle 720 slidably clamped on both sides of the solution static box 718 gradually move towards the direction close to the solution static box 718 and abut against each other, separating the solution static box 718 into three chambers, so that the neutral oil, hydrated phospholipids, water and water-soluble impurities after static stratification in the solution static box 718 are completely separated, in order to classify and process the neutral oil, hydrated phospholipids, water and water-soluble impurities. At the same time, compared with the vertically arranged solution static box 718, the inclined solution static box 718 only needs the hydrated phospholipids to move the horizontal projection distance along the inclined plane, driving the heavy-phase solution to slide downward along the inclined plane, and the light-phase solution to gather upward, forming a dynamic separation interface, significantly accelerating the static stratification of the hydrated phospholipids. A sealing rubber pad for strengthening the sealing performance is arranged at the outer edge of the plug-in end 724 where the separation baffles 720 are mutually matched, so that the fit between the separation baffles 720 is closer, in order to prevent the solution in other solution storage chambers 726 from flowing into the solution storage chamber 726 being aspirated through the gap between the separation baffles 720 when aspirating the solution in one of the solution storage chambers 726, effectively ensuring the isolation effect of the separation baffles 720 on the solution. Moreover, for the mutually cooperating plug-in ends 724 of the two separation baffles 720, one end is a wedge block with a narrow front and a wide rear, and the other end is a wedge groove matching the wedge block, making the mutual fitting process of the two separation baffles 720 smoother, and at the same time providing support for each other after fitting to overcome the bending of the separation baffles 720 caused by their own gravity, so that the two separation baffles 720 can always maintain a good fit; On the other hand, the conical sleeve 722 is rotationally clamped at the bottom of the solution static box 701 and is coaxially arranged with the solution static box 701. At the same time, through the cooperation between the sliding block 727 fixedly arranged at the top of the conical sleeve 722, the second ball group 728 and the sliding groove 729, and the sliding cooperation between the third ball group 730 fixedly arranged at the bottom of the conical sleeve 722 and the second ball groove 731, the movement resistance of the conical sleeve 722 during rotation on the solution static box 701 and the bottom plate 703 is reduced, and the smoothness of the rotation of the conical sleeve 722 is improved. Among them, the first waste liquid recovery box 732 and the second waste liquid recovery box 733 are both rotationally arranged on the conical sleeve 722. Moreover, through a plurality of fixing plates 734 circumferentially arranged on the outer side of the first waste liquid recovery box 732, the first waste liquid recovery box 732 and the solution static box 701 are fixedly arranged in the tank body 1, and at the same time, support is provided for the centrifugal part 4 to keep the centrifuge 401 stable during rotation. The outer sides of the first waste liquid recovery box 732 and the second waste liquid recovery box 733 are respectively provided with a first liquid diversion pipe and a second liquid diversion pipe penetrating through the tank body 1. The ends of the first liquid diversion pipe and the second liquid diversion pipe extending outside the tank body 1 are respectively communicated with a recovery device for collecting neutral oil, water and water-soluble impurities. The second waste liquid recovery box 733 is relatively stationary with the tank body 1 through the second liquid diversion pipe penetrating through the tank body 1. Therefore, when the conical sleeve 722 rotates driven by the second speed reducer 758 and the fourth driving motor 753, the conical sleeve 722 can rotate itself while not driving the first waste liquid recovery box 732 and the second waste liquid recovery box 733 to rotate.

[0049] Refer to Figures 13-15As shown, a phospholipid diversion pipe 737 that cooperates with the drain pipe 719 is provided on the conical sleeve 722. A first telescopic sleeve 738 that cooperates with the drain pipe 719 is provided on the phospholipid diversion pipe 737. The first telescopic sleeve 738 includes a first fixed pipe 739 and a first telescopic pipe 740. The first telescopic pipe 740 is provided at one end of the first fixed pipe 739 and is slidably clamped outside the first fixed pipe 739. A first guiding block 741 is fixedly provided at one end of the first telescopic pipe 740 close to the first fixed pipe 739. A first adjusting screw 742 is threadedly connected to the top end of the first guiding block 741. A plurality of second telescopic sleeves 743 that cooperate with the drain pipe 719, the first liquid recovery pipe 735 and the second liquid recovery pipe 736 are provided on the conical sleeve 722. Sealing pieces 744 that match the ends of the first telescopic sleeve 738 and the second telescopic sleeve 743 are fixedly provided on the drain pipe 719, the first liquid recovery pipe 735 and the second liquid recovery pipe 736. The second telescopic sleeve 743 includes a second fixed pipe 745 and a second telescopic pipe 746. The second telescopic pipe 746 is provided at both ends of the second fixed pipe 745 and is slidably clamped outside the second fixed pipe 745. Second guiding blocks 747 are fixedly provided at the opposite ends of the two second telescopic pipes 746. A second adjusting screw 748 is threadedly connected to the top end of the second guiding block 747. Both ends of the second adjusting screw 748 are rotatably provided on the conical sleeve 722. First synchronous pulleys 749 are fixedly provided on both the first adjusting screw 742 and the second adjusting screw 748. A synchronous belt 750 is sleeved outside the first synchronous pulley 749. A second synchronous pulley 751 is sleeved at one end of the synchronous belt 750 away from the first synchronous pulley 749. A second rotating shaft 752 is fixedly provided in the middle of the second synchronous pulley 751. The second rotating shaft 752 is rotatably provided in the conical sleeve 722. A fourth driving motor 753 is fixedly provided at one end of one of the second rotating shafts 752. A gear 754 is fixedly provided on the second rotating shaft 752. A toothed belt 755 is meshed outside the plurality of gears 754.

[0050] It should be noted that ball valves are provided on the first liquid recovery pipe 735, the second liquid recovery pipe 736 and the drain pipe 719 to close the first liquid recovery pipe 735, the second liquid recovery pipe 736 and the drain pipe 719, so as to prevent the solutions in the first waste liquid recovery tank 732, the second waste liquid recovery tank 733 and the solution static box 718 from accidentally flowing out when not connected to the second telescopic sleeve 743. The number of the first liquid recovery pipe 735 and the second liquid recovery pipe 736 provided on the first waste liquid recovery tank 732 and the second waste liquid recovery tank 733 corresponds to the number of the solution static boxes 718. The ends of the first liquid recovery pipe 735 and the second liquid recovery pipe 736 close to the conical sleeve 722 are respectively embedded in the first waste liquid recovery tank 732 and the second waste liquid recovery tank 733 to avoid unnecessary movement interference between the conical sleeve 722 and the first liquid recovery pipe 735 and the second liquid recovery pipe 736 when the conical sleeve 722 rotates. The thread on the second adjusting screw 748 is designed as two reverse-threaded left-hand and right-hand threads, so that when the second adjusting screw 748 rotates, the two second guiding blocks 747 threadedly connected thereto can move in two opposite directions, either away from or towards each other, so that the second telescopic pipe 746 fixedly connected to the bottom end of the second guiding block 747 can telescopically move on the second fixed pipe 745. The thread helix direction of the first adjusting screw 742 is the same as and the pitch is equal to that of one section of the thread of the first adjusting screw 742 close to the second adjusting screw 748, so that the second guiding plate threadedly connected to the first adjusting screw 742 and the first guiding plate threadedly connected to the second adjusting screw 748 move the same distance. Moreover, the side line of the toothed belt 755 is parallel to the generatrix of the conical sleeve 722, so that the second rotating shaft 752, the gear 754 and the toothed belt 755 can be installed and operate normally in the conical sleeve 722.

[0051] During use, start the fourth driving motor 753 to drive the second rotating shaft 752 to rotate, and drive the gear 754 on the second rotating shaft 752 to rotate. Then, through the toothed belt 755 sleeved outside the gear 754, drive the three second rotating shafts 752 to rotate synchronously, so that the second rotating shaft 752 drives the first synchronous pulley 749 to rotate through the second synchronous pulley 751 fixedly arranged in the middle thereof and the synchronous belt 750 sleeved outside the second synchronous pulley 751. Thus, the first synchronous pulley 749 drives the first adjusting screw 742 and the second adjusting screw 748 to rotate in the conical sleeve 722, so that the first guiding blocks 741 and the second guiding blocks 747 threadedly connected to the first adjusting screw 742 and the second adjusting screw 748 drive the first telescopic pipe 740 and the second telescopic pipe 746 fixedly connected to their bottoms to telescopically move on the first fixed pipe 739 and the second fixed pipe 745 respectively, so that the first telescopic pipe 740 is inserted into the drain pipe 719, and the second telescopic pipe 746 is inserted into the first liquid recovery pipe 735, the second liquid recovery pipe 736 and the drain pipe 719.

[0052] Refer to Figure 6 And Figures 16-18 As shown, the bottom end of the phospholipid diversion pipe 737 is connected to a second rotor pump 756. A first mounting plate 757 for facilitating the installation of the second rotor pump 756 is fixedly arranged at the bottom of the second rotor pump 756. The first mounting plate 757 is fixedly arranged at the bottom of the conical sleeve 722. A second speed reducer 758 is fixedly arranged in the middle of the bottom end of the conical sleeve 722. The input end of the second speed reducer 758 is connected to a fifth driving motor 759. The second speed reducer 758 and the fifth driving motor 759 are fixedly provided with a second mounting plate 760 at the bottom. The second mounting plate 760 is fixedly arranged on the falling film evaporation tank 501. A second driving motor 503 for driving the rotating scraper 502 is arranged at the bottom of the second mounting plate 760. A plurality of second transfer pipes 761 matching with the second rotor pump 756 are arranged at the top end of the falling film evaporation tank 501. The second transfer pipes 761 are movably clamped at the top end of the falling film evaporation tank 501. A plurality of third compression springs 762 are arranged on the second transfer pipes 761. Both ends of the third compression springs 762 are respectively abutted against the outer edge of the second transfer pipes 761 and the top wall of the falling film evaporation tank 501. A second blocking block 763 for blocking the second transfer pipes 761 is arranged on one side of the second transfer pipes 761. A second guiding slider 764 is fixedly arranged on one side of the second blocking block 763. A second connecting rod 765 is fixedly arranged on one side of the second guiding slider 764. One end of the second connecting rod 765 is fixedly connected to a third rotating shaft 766. An installation groove 767 for facilitating the installation of the second guiding slider 764, the second connecting rod 765 and the third rotating shaft 766 is formed on the falling film evaporation tank 501. The second guiding slider 764 and the second connecting rod 765 are both slidably clamped in the installation groove 767 with the third rotating shaft 766 as the center. On a section of the second guiding slider 764 located in the installation groove 767, arc-shaped springs 768 are fixedly abutted on both sides. Both ends of the arc-shaped springs 768 are respectively fixedly connected to the second guiding slider 764 and the inner wall of the installation groove 767. Both ends of the arc-shaped springs 768 are respectively fixedly connected to the second guiding slider 764 and the inner wall of the installation groove 767.

[0053] It should be noted that the outer edge of the top end of the second transfer pipe 761 is designed in a conical shape that is narrow at the top and wide at the bottom, so as to cooperate with a plurality of third compression springs 762 fixedly connected to its bottom, enabling the second transfer pipe 761 to gradually apply pressure to the third compression springs 762 under the extrusion of the output end of the second rotor pump 756 and the second plugging block 763, causing them to contract, so that the second transfer pipe 761 is always retracted into the falling film evaporation tank 501 until it is flush with the top end of the falling film evaporation tank 501. At this time, the second transfer pipe 761 will always abut against the output end of the second rotor pump 756 or the second plugging block 763 under the action of the third compression springs 762, so as to ensure good sealing between the second transfer pipe 761 and the output end of the second rotor pump 756 and the second plugging block 763, to prevent the hydrated phospholipids from flowing out through the gap between the output end of the second rotor pump 756 and the second transfer pipe 761 during transportation, or to prevent the water vapor generated by the operation of the falling film evaporation section 5 from flowing into the falling film evaporation tank 501 through the gap between the second transfer pipe 761 and the second plugging block 763, enabling the falling film evaporation tank 501 to maintain good sealing. Moreover, when the second transfer pipe 761 is in a state where its top end is flush with the top end of the falling film evaporation tank 501, its bottom end is lower than the bottom plane of the top end of the falling film evaporation tank 501, thereby preventing the hydrated phospholipids flowing through the second transfer pipe 761 from flowing into the groove where the third compression springs 762 are installed through the bottom end of the second transfer pipe 761, effectively ensuring the utilization rate of resources; On the other hand, the cross-sectional dimension of the second plugging block 763 is larger than that of the second transfer pipe 761, so that the second plugging block 763 can fit well on the surface of the second transfer pipe 761 to block it, preventing the water vapor generated by the operation of the falling film evaporation section 5 from flowing into the falling film evaporation tank 501 through the fitting gap between the second plugging block 763 and the second transfer pipe 761, so as to prevent the combination of water vapor and hydrated phospholipids, further controlling the water content inside the hydrated phospholipids and effectively ensuring the purity of the hydrated phospholipids. When the arc spring two 768 is in a free state, the extension degree makes the guide slider two 764 located in the middle of the outer edge of the installation groove two 767. At this time, the second plugging block 763 fixedly connected to the guide slider two 764 fits on the surface of the second transfer pipe 761 to block it. When the guide slider two 764 is squeezed by the output end of the second rotor pump 756, the arc springs two 768 on both sides of the guide slider two 764 are respectively subjected to compressive and tensile forces, causing the guide slider two 764 to slide inside the installation groove two 767 with the third rotating shaft 766 as the center and driving the second plugging block 763 to separate from the second transfer pipe 761, so that the output end of the second rotor pump 756 covers the second transfer pipe 761, in order to transport the hydrated phospholipids into the static module 702 for static settlement. Moreover, the elastic force of the arc spring two 768 is greater than the elastic force of the third compression spring 762, so that when the second plugging block 763 is reset, it squeezes the second transfer pipe 761, causing it to retract into the falling film evaporation tank 501 again and abut against the bottom wall of the second plugging block 763.

[0054] In this embodiment, the hydrated phospholipids separated by centrifugation flow into the solution static box 718 in the solution static box 701 for static layering, so that the hydrated phospholipids are divided into three layers, neutral oil, hydrated phospholipids, water and water-soluble impurities in the solution static box 718, and are discharged and collected through the first liquid recovery pipe 735 and the second liquid recovery pipe 736, making full use of resources. At the same time, since the hydrated phospholipids obtained by static settlement only contain a small amount of neutral oil, water and water-soluble impurities, it is not easy to cause blockage and corrosion of the tube wall of the falling film evaporator during the falling film evaporation process.

[0055] During use, the hydrated phospholipids separated by the centrifuge 401 are discharged into the solution transfer box 403, and the third drive motor 708 is started to drive the first reducer 707 to rotate, so that the turntable 704 rotates clockwise at the bottom of the solution transfer box 403, and drives the first rotor pump 709 fixedly arranged on the turntable 704 to rotate clockwise. During this process, the output end of the first rotor pump 709 gradually squeezes the first transfer pipe 710, causing the transfer pipe 710 to exert pressure on the first compression spring 711, and making the transfer pipe 710 always contract in the solution static box 701 until it is flush with the top of the solution static box 701. At the same time, the output end of the first rotor pump 709 will also squeeze the plug block 712 covering the transfer pipe 710. The guide slider 713 fixedly arranged on the plug block 712 will correspondingly squeeze and stretch the arc springs 717 arranged on both sides of it, causing the guide slider 713 to slide inside the installation groove 716 with the first rotating shaft 715 as the center, and driving the plug block 712 to separate from the transfer pipe 710, so that the output end of the first rotor pump 709 covers the transfer pipe 710. At this time, the third drive motor 708 stops, and the transfer pipe 710 will always abut against 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 is preset with a threshold value so that the total amount of hydrated phospholipids discharged at one time does not exceed the actual volume of the solution static box 718, and the hydrated phospholipids in the solution transfer box 403 are transported to the solution static box 718 corresponding to the transfer pipe 710. When the solution static box 718 is gradually filled with hydrated phospholipids, the first rotor pump 709 is stopped, and then the third drive motor 708 is started again, so that the first reducer 707 drives the turntable 704 to rotate clockwise at the bottom of the solution transfer box 403. During this process, the output end of the first rotor pump 709 gradually separates from the transfer pipe 710, and the transfer pipe 710 will pop out of the solution static 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 plug block 712, the plug block 712 will reset under the action of the arc spring 717 and squeeze the transfer pipe 710, causing it to retract into the solution static box 701 again. When the output end of the first rotor pump 709 driven by the turntable 704 covers the next transfer pipe 710, the third drive motor 708 stops, and the first rotor pump 709 is started to transport the hydrated phospholipids. Then, this operation is repeated in turn until the output end of the first rotor pump 709 covers the last transfer pipe 710 for transportation. Then, the third drive motor 708 is started again and drives the turntable 704 to rotate counterclockwise. After the first rotor pump 709 rotates to the initial position, the third drive motor 708 stops; After the hydrated phospholipids in the solution static box 718 are completely static and stratified, start the fifth driving motor 759 to drive the second speed reducer 758 to rotate, so that the tapered sleeve 722 rotates clockwise at the bottom of the solution static box 701, and drives the second rotor pump 756 fixedly arranged on the tapered sleeve 722 to rotate clockwise. During this process, the output end of the second rotor pump 756 gradually squeezes the first transfer pipe two 761, causing the transfer pipe two 761 to exert pressure on the third compression spring 762, and keeping the transfer pipe two 761 always retracted in the falling film evaporation tank 501 until it is flush with the top of the falling film evaporation tank 501. At the same time, the output end of the second rotor pump 756 will also squeeze the blocking block two 763 covering the transfer pipe two 761. The guiding slider two 764 fixedly arranged on the blocking block two 763 will correspondingly squeeze and stretch the arc springs two 768 arranged on both sides of it, causing the guiding slider two 764 to slide inside the installation groove two 767 with the third rotating shaft 766 as the center, and driving the blocking block two 763 to separate from the transfer pipe two 761, so that the output end of the second rotor pump 756 covers the transfer pipe two 761. At this time, the fifth driving motor 759 stops, and the transfer pipe two 761 will always abut against the output end of the second rotor pump 756 under the action of the third compression spring 762. Then start the airbag extrusion assembly 723 arranged on the tapered sleeve 722 to inflate the airbags arranged on both sides of the partition baffle 720 and squeeze the partition baffle 720, so that the partition baffle 720 slidingly clamped on both sides of the solution static box 718 gradually moves towards the direction close to the solution static box 718 and abuts against each other, dividing the solution static box 718 into three chambers, completely separating the neutral oil, hydrated phospholipids, water and water-soluble impurities after static stratification in the solution static box 718. Then start the fourth driving motor 753 to drive the second rotating shaft 752 to rotate, and drive the gear 754 on the second rotating shaft 752 to rotate. Then, through the toothed belt 755 sleeved outside the gear 754, drive the three second rotating shafts 752 to rotate synchronously, so that the second rotating shaft 752 drives the first synchronous belt wheel 749 to rotate through the second synchronous belt wheel 751 fixedly arranged in the middle of it and the synchronous belt 750 sleeved outside the second synchronous belt wheel 751. Thus, the first synchronous belt wheel 749 drives the first adjusting screw 742 and the second adjusting screw 748 to rotate in the tapered sleeve 722, so that the first guiding block 741 and the second guiding block 747 threadedly connected to the first adjusting screw 742 and the second adjusting screw 748 drive the first telescopic tube 740 and the second telescopic tube 746 fixedly connected to their bottoms to perform corresponding telescoping on the first fixed tube 739 and the second fixed tube 745 respectively, so that the first telescopic tube 740 is inserted into the drain pipe 719, the second telescopic tube 746 is inserted into the first liquid recovery pipe 735, the second liquid recovery pipe 736 and the drain pipe 719.Then, control the ball valves on the corresponding liquid discharge pipe 719, the first liquid recovery pipe 735, and the second liquid recovery pipe 736 to open, so that the neutral oil, water, and water-soluble impurities stratified in the solution static box 718 flow into the recovery device through the first liquid recovery pipe 735 and the second liquid recovery pipe 736 respectively; Then, start the second rotor pump 756 to transport the hydrated phospholipids in the solution static box 718 to the falling film evaporation tank 501. When all the hydrated phospholipids in the solution static box 718 are completely pumped out, stop the second rotor pump 756, and repeat the above operation until all the hydrated phospholipids statically placed in the last solution static box 718 are pumped out and transported to the falling film evaporation tank 501. Then, the fifth driving motor 759 is started again to drive the tapered sleeve 722 to rotate counterclockwise. After the second rotor pump 756 rotates to the initial position, the fifth driving motor 759 stops.
