[0002] Egg yolk antibodies (IgY) are immunoglobulins produced by laying hens after immunization with specific antigens and transferred and stored in the yolk. Due to their advantages such as good antigen-specific recognition, safety with no residue, and readily available raw materials, they are widely recognized in disease prevention and control.
[0003] The current laboratory preparation method for egg yolk globulin includes: diluting egg yolk with water, adding citric acid to adjust the pH value, then placing the solution in a refrigerator at 4°C overnight. The next day, the solution is taken out, centrifuged and the supernatant is collected. Citric acid is added again to adjust the pH value, an appropriate amount of sodium chloride is added and stirred evenly, and the solution is left to stand in a refrigerator at 4°C for six hours. The precipitate is then collected by centrifugation.

[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0047] The purpose of this invention is to provide an egg yolk globulin powder extraction system to solve the problems existing in the prior art, improve the extraction efficiency of egg yolk globulin powder, and reduce the labor intensity of experimental personnel.
[0048] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0049] like Figure 1 As shown, this embodiment provides an egg yolk globulin powder extraction system, including a water purification device, a refrigeration unit 200, an acidification tank 300, a flocculation tank 400, a filter assembly, and a freeze dryer 800. The water purification device's inlet is connected to a tap water source via a pipeline. The water purification device is used to purify tap water into pure water; the tap water source can be a common faucet or other pipeline capable of delivering tap water. The water purification device's outlet is connected to the inlets of the refrigeration unit 200, the acidification tank 300, and the flocculation tank 400, respectively, to provide them with the required pure water. The acidification tank's outlet is connected to the flocculation tank's inlet, the flocculation tank's outlet is connected to the filter assembly's inlet, and the filter assembly's outlet is connected to the freeze dryer's inlet. The outer wall of the flocculation tank body 400 is provided with a flocculation tank jacket, and the outer side of the filter assembly is provided with a filter assembly jacket. The coolant outlet of the refrigeration unit body 200 is connected to the flocculation tank jacket and the filter assembly jacket respectively, so as to supply coolant to the flocculation tank body 400 and the filter assembly, so that they are always kept at a suitable low temperature, usually controlled at 4℃-8℃, in order to protect the antibody activity.
[0050] In actual use, the water purification device is first activated to purify ordinary water (i.e., tap water) into high-purity water. The prepared pure water is then piped to the acidification tank 300 and the flocculation tank 400 for preparing relevant solutions. The refrigeration unit 200 is turned on, which provides coolant to the flocculation tank 400 and the filter components, maintaining them in a low-temperature environment. The collected egg yolk material is poured into the acidification tank 300, and an appropriate amount of pure water is injected into the acidification tank 300 through a pipe connected to the pure water machine 100 to initially dilute the egg yolk material. Precisely measured amounts of acid solution (including but not limited to citric acid) are slowly added, and the pH value of the solution is monitored in real time. The acidification process lasts for 30-40 minutes. During this period, the proteins in the egg yolk undergo an acidification reaction, initially separating some impurities. The low-temperature environment effectively maintains the activity of egg yolk globulin. After acidification, the solution in the acidification tank 300 flows by gravity into the flocculation tank 400 through a pipeline. Similarly, a suitable amount of pure water is added to the flocculation tank 400 via the pure water system 100 to further dilute the solution. A measured amount of flocculant (including but not limited to sodium chloride) is slowly added. The flocculant combines with impurities in the solution, gradually forming larger flocculent particles. The flocculation process lasts for 20-30 minutes. The refrigeration unit 200 continuously supplies coolant to the flocculation tank jacket to provide a low-temperature environment, enhancing the separation of impurities from egg yolk globulin and ensuring the stability of the egg yolk globulin. The flocculated solution is then transported through pipelines to the filter assembly, where the solution undergoes layer-by-layer filtration to increase the concentration of egg yolk globulin, providing high-quality raw materials for subsequent freeze-drying operations. Finally, the filtered and concentrated egg yolk globulin solution enters the freeze dryer body 800. The solution is evenly placed on the material tray of the freeze dryer body 800. The freeze drying parameters are set, and the temperature is first rapidly lowered to -40℃ to -50℃ to freeze the solution. Then, the temperature is slowly raised in a vacuum environment of 10-20Pa to allow the water to sublimate. The entire freeze drying process lasts for 12-15 hours, and finally the egg yolk globulin is dried into powder for long-term storage and subsequent use.
[0051] In this embodiment, the water purification device is a pure water machine body 100, and the pure water machine body 100 adopts an existing pure water machine, such as... Figure 1The pure water machine body 100 shown includes three parts: an industrial control computer, a pure water filtration module, and a water storage tank. The pure water filtration module consists of several existing filters connected in series, including but not limited to existing quartz sand filters, activated carbon filters, security filters, and reverse osmosis membranes. Researchers can add or remove filters as needed; the configuration is not unique. Tap water from the municipal water supply passes through the industrial control computer and flows to the pure water filtration module. A first pure water filtration valve 102 is installed on the pipeline between the industrial control computer and the pure water filtration module to control the flow between them. A second pure water filtration valve 103 is installed on the pipeline between the pure water filtration module and the water storage tank to control the flow between them. A tap water pressure valve 101 is installed on the pipeline connecting the pure water machine body 100 to the municipal water supply to regulate the tap water pressure. The water outlet pipe of the pure water machine body 100 is connected to the pure water main pipe A00. The pure water main pipe A00 is equipped with a pure water main pipe valve 104 and a pure water main pipe delivery pump 105. The pure water main pipe valve 104 is used to control the flow of pure water in the pure water main pipe A00, while the pure water main pipe delivery pump 105 provides power for the pure water in the pure water main pipe A00.
[0052] In this embodiment, the end of the main pure water pipe A00 furthest from the pure water machine body 100 is connected to a first pure water branch pipe A01, a second pure water branch pipe A02, and a third pure water branch pipe A03. These three branches are connected in parallel, and their connection relationships are as follows:
[0053] The first pure water branch pipe A01, located away from the main pure water pipe A00, is connected to the water inlet of the chiller body 200. A chiller inlet pressure valve 201 is installed on the first pure water branch pipe A01 to control the pure water inlet pressure of the chiller body 200. During the circulation process, some coolant may be lost from the chiller body 200; the first pure water branch pipe A01 can be used to replenish it with pure water (i.e., coolant).
[0054] The end of the second pure water branch pipe A02 away from the pure water main pipe A00 is connected to the water inlet of the acidification tank body 300. The second pure water branch pipe A02 is equipped with an acidification tank inlet pressure valve 301. The acidification tank inlet pressure valve 301 is used to control the pressure of pure water flowing into the acidification tank body 300. The pure water here is used to dilute the egg yolk raw material in the acidification tank body 300.
[0055] The end of the third pure water branch pipe A03 away from the pure water main pipe A00 is connected to the inlet of the flocculation tank body 400. The third pure water branch pipe A03 is equipped with a flocculation tank inlet pressure valve 401, which is used to control the pressure of pure water flowing into the flocculation tank body 400. The pure water here is used to dilute the solution in the flocculation tank body 400.
[0056] In addition, the pure water main pipe A00 can also be connected to the filter assembly and the freeze dryer body 800 through additional branches for equipment cleaning and maintenance, ensuring that the entire extraction system is in a pure and impurity-free state and avoiding contamination of egg yolk globulin.
[0057] In this embodiment, regarding the specific structure of the acidification tank body 300, an acidification tank stirring device is provided on the acidification tank body 300. The acidification tank stirring device includes an acidification tank stirring motor 302, which is fixed to the top outer side of the acidification tank body 300. The output shaft of the acidification tank stirring motor 302 is connected to an acidification tank stirring shaft, which passes through the acidification tank body 300 and extends into the interior of the acidification tank body 300. Multiple acidification tank stirring blades are provided at the lower end of the acidification tank stirring shaft, and the acidification tank stirring blades are located inside the acidification tank body 300. In actual use, the acidification tank stirring motor 302 can be started to drive the acidification tank stirring blades to rotate, thereby fully and uniformly stirring the solution inside the acidification tank body 300. During the stirring process, acid (including but not limited to citric acid) can be added.
[0058] An acidification tank temperature gauge 303 is also installed at the upper end of the acidification tank body 300 to monitor the internal temperature of the acidification tank body 300. The upper end of the acidification tank body 300 is also provided with an acidification tank opening 304, through which the experimenter can pour a certain amount of acid solution and egg yolk raw material into the acidification tank body 300.
[0059] The lower end of the acidification tank body 300 is provided with an acidification tank sampling port 307 and an acidification tank outlet. The sampling port 307 and the outlet are two outlets located at the bottom of the acidification tank body 300. Alternatively, an outlet pipe can be provided at the bottom of the acidification tank body 300, with the sampling port 307 and the outlet being two branches of this outlet pipe. Regardless of the method used, the sampling port 307 and the outlet are connected in parallel. An acidification tank sampling valve 306 is provided at the sampling port 307. The sampling valve 306 controls the flow through the sampling port 307. If it is necessary to test the pH value of the solution inside the acidification tank body 300, the sampling valve 306 can be opened to collect a sample solution from the sampling port 307, thereby measuring its pH value. In addition, to monitor the pH value inside the acidification tank 300 in real time, a pH meter can be installed on the acidification tank 300 to monitor the internal pH value. An acidification tank outlet valve 305 is installed on the pipeline between the outlet of the acidification tank and the inlet of the flocculation tank 400. The acidification tank outlet valve 305 is used to control the flow of solution from the acidification tank 300 to the flocculation tank 400.
[0060] In practical use, the collected egg yolk material is poured into the acidification tank body 300. An appropriate amount of pure water is injected into the acidification tank body 300 through the second pure water branch pipe A02 to initially dilute the egg yolk material. The agitator in the acidification tank is turned on, and the inlet pressure valve 301 is adjusted to a suitable pressure. During the agitation process, the temperature gauge 303 of the acidification tank is closely monitored. Precisely measured amounts of acid are slowly added, while the pH value of the solution is monitored in real time. A sample is taken from the sampling port 307 of the acidification tank to detect changes in the pH of the material. The acidification process lasts for 30-40 minutes. During this period, the proteins in the egg yolk undergo an acidification reaction, initially separating some impurities. The low-temperature environment effectively maintains the activity of the yolk globulin.
[0061] In this embodiment, a flocculation tank agitator is provided on the flocculation tank body 400. The flocculation tank agitator is used to agitate the solution inside the flocculation tank body 400. The flocculation tank agitator includes a flocculation tank agitator motor 404, which is installed on the outer top of the flocculation tank body 400. The output shaft of the flocculation tank agitator motor 404 is connected to a flocculation tank agitator shaft. The lower end of the flocculation tank agitator shaft passes through the flocculation tank body 400 and is located inside the flocculation tank body 400. The flocculation tank agitator shaft is provided with multiple flocculation tank agitator blades, which are located inside the flocculation tank body 400. In actual use, the flocculation tank agitator motor 404 can be started to drive the flocculation tank agitator blades to rotate, thereby fully and uniformly agitating the solution inside the flocculation tank body 400. During the agitation process, flocculants (including but not limited to sodium chloride) can be added to ensure that the flocculant is fully mixed with the solution.
[0062] The top of the flocculation tank body 400 is equipped with a flocculation tank vent, and a flocculation tank vent valve 402 is installed at the vent. When the internal air pressure of the flocculation tank body 400 is high, the flocculation tank vent valve 402 can be opened to release some gas, thereby maintaining the stability of the internal air pressure of the flocculation tank body 400. The top of the flocculation tank body 400 is also equipped with a flocculation tank pressure gauge 403 and a flocculation tank temperature gauge 405. The pressure gauge 403 is used to monitor the internal pressure of the flocculation tank body 400, and the temperature gauge 405 is used to monitor the internal temperature of the flocculation tank body 400. The top of the flocculation tank body 400 is equipped with a flocculation tank opening 406, through which operators can add flocculant into the flocculation tank body 400. A flocculation tank inlet pressure valve 407 is installed at the inlet of the flocculation tank body 400. The solution from the acidification tank body 300 will pass through the flocculation tank inlet pressure valve 407 and then enter the interior of the flocculation tank body 400. The flocculation tank inlet pressure valve 407 can control the pressure of the solution from the acidification tank body 300.
[0063] The lower end of the flocculation tank body 400 is provided with a flocculation tank sampling port 411 and a flocculation tank outlet. The flocculation tank sampling port 411 and the flocculation tank outlet are set in the same way as the acidification tank sampling port 307 and the acidification tank outlet mentioned above, so they will not be described again. A flocculation tank sampling valve 410 is provided at the flocculation tank sampling port 411. By opening the flocculation tank sampling valve 410, the sample liquid inside the flocculation tank body 400 can be taken out and tested. A flocculation tank outlet valve 409 is provided on the pipeline between the flocculation tank outlet and the inlet of the filter assembly.

The flocculant delivery pump 413 is used to provide power for the liquid delivery in the pipeline, and the flocculant flow meter 414 is used to monitor the flow rate in the pipeline.
[0064] After acidification, the solution in the acidification tank 300 flows by gravity into the flocculation tank 400 through a pipe. The pure water machine 100 adds an appropriate amount of pure water to the flocculation tank 400 through the third pure water branch pipe A03 to further dilute the solution. The flocculation tank stirring device is started, and the flocculation tank inlet pressure valve 401 and the flocculation tank liquid inlet pressure valve 407 are adjusted to suitable pressures. The changes in the flocculation tank pressure gauge 403 and the flocculation tank temperature gauge 405 are observed. A measured amount of flocculant is slowly added. The flocculant combines with impurities in the solution, gradually forming larger flocculent particles. Samples are taken periodically from the flocculation tank sampling port 411 for testing. The flocculation process lasts 20-30 minutes. The refrigeration unit 200 continuously provides a low-temperature environment for the flocculation tank 400, enhancing the separation effect between impurities and egg yolk globulin and ensuring the stability of egg yolk globulin.
[0065] In this embodiment, the filtration assembly includes a primary filter 500, a secondary filter 600, and a tertiary filter 700 connected in sequence.

Through triple filtration, impurities in the solution can be effectively removed.
[0066] In this embodiment, the primary filter 500, secondary filter 600, and tertiary filter 700 are all existing cross-flow filters.

Of course, operators can adjust the specific pore size of each filter membrane according to actual needs; it is not limited to this one method.
[0067] In this embodiment, the primary filter 500 includes a primary feed tank, a first-stage membrane module, and two second-stage membrane modules. The membrane module consists of a filter membrane and a housing surrounding it. The filter membrane includes, but is not limited to, existing ceramic membranes, which are inherent structures of existing cross-flow filters; therefore, their details will not be elaborated further.

The filtrate outlets of the two second-stage membrane modules are connected to the secondary filter 600, and the feed liquid outlets of the two second-stage membrane modules are connected to the circulating feed liquid inlet of the primary feed tank. In actual use, the solution flowing out of the flocculation tank 400 first enters the primary feed tank. The liquid in the primary feed tank flows into the first-stage membrane module for preliminary filtration. The filtered liquid then enters the second-stage membrane module. The filtrate flowing out of the outlet of the second-stage membrane module flows into the secondary filter 600. The feed liquid flowing out of the outlet of the second-stage membrane module flows back into the primary feed tank, thus entering the next cycle.

The inlet of the three-stage feed tank is connected to the filtrate outlet of the second-stage and third-stage membrane modules, and the outlet of the three-stage feed tank is connected to the inlet of the first-stage and third-stage membrane modules. The outlet of the first-stage and third-stage membrane modules is connected to the inlets of the two second-stage and third-stage membrane modules, and the filtrate outlets of the two second-stage and third-stage membrane modules are connected to a filtrate collection container. Unlike the one-stage filter 500 and the two-stage filter 600, the feed outlets of the two second-stage and third-stage membrane modules are connected to the circulating feed inlet of the three-stage feed tank, and the product solution outlet of the three-stage feed tank is connected to a freeze dryer. In actual use, the filtrate flowing out of the second and third stage membrane modules first enters the third stage feed tank. The liquid in the third stage feed tank flows into the first and third stage membrane modules for preliminary filtration. The filtered liquid then flows into the second and third stage membrane modules respectively. The filtrate flowing out of the outlets of the second and third stage membrane modules flows into the filtrate collection container for collection. The feed liquid flowing out of the outlets of the second and third stage membrane modules flows back into the third stage feed tank. Finally, the solution in the third stage feed tank flows into the freeze dryer body 800 through pipelines.
