Description

Technical Field

[0001] This invention belongs to the field of ergosterol extraction technology, specifically a device for preparing ergosterol in functional beverages. Background Technology

[0002] Ergosterol is a key sterol component in the cell membranes of fungi and yeast. It is a precursor to vitamin D2 and can be converted into vitamin D2 after being exposed to ultraviolet light. In recent years, with the booming development of the functional food and beverage market, ergosterol has been increasingly used in various functional beverages as a high-value natural active ingredient due to its potential effects in promoting calcium absorption, enhancing immunity, and anti-oxidation.

[0003] Currently, industrial methods for preparing ergosterol from fungal biomass typically rely on traditional solvent extraction and purification processes. A typical workflow includes cell disruption, solvent extraction, saponification, concentration and crystallization, and separation and purification. However, this traditional process has several inherent drawbacks:

[0004] 1. Each unit operation needs to be carried out step by step in different independent equipment. The transfer of materials between different equipment not only leads to long production cycles and low efficiency, but also increases the risk of material loss and cross-contamination, making it difficult to meet the requirements of modern food industry for continuous and closed production.

[0005] 2. Traditional hot reflux extraction or stirring extraction methods have low mass transfer efficiency and require a long time. The long heating process can easily lead to oxidation and isomerization of heat-sensitive ergosterol, reducing its biological activity and yield. Incomplete cell disruption will also directly affect the final extraction efficiency.

[0006] 3. Traditional purification methods heavily rely on multi-step solvent extraction and repeated crystallization operations. In particular, the control of supersaturation during the crystallization process often depends on experience and is difficult to control accurately. This can easily lead to problems such as excessively rapid crystal nucleation, uneven crystal form, and inclusion of impurities, which affect the purity and yield of the final product. At the same time, the use of large amounts of solvent also brings high recycling costs and environmental pressure. Summary of the Invention

[0007] The purpose of this invention is to achieve highly efficient and synergistic extraction through the use of a crushing mechanism, significantly improving efficiency and yield. By integrating an ultrasonic crushing generator and a microwave heating module into the same reaction vessel, the synergistic effect of physical crushing and thermal extraction is realized. Ultrasonic waves utilize cavitation to instantly destroy cell walls and release contents, while microwaves provide rapid and uniform internal heating, greatly accelerating the mass transfer rate. This synergy shortens the ergosterol extraction process from several hours to several minutes, resulting in high extraction efficiency and short extraction time. Simultaneously, it avoids degradation of active ingredients caused by prolonged heating, leading to a higher yield. The use of a discharge mechanism allows for seamless switching between extraction and purification stages within the same device, achieving process integration and continuity, significantly shortening the cycle time, and reducing material transfer losses and contamination risks. Multiple interconnected control components and limit designs ensure process stability. Furthermore, the limit components of the discharge mechanism and the bottom agitator share a support structure, greatly simplifying the overall design of the vessel, making the internal structure compact, maximizing space utilization, and facilitating manufacturing and maintenance. The use of a filter membrane enables in-situ purification and concentration, achieving continuous process and improved quality. This system features a built-in filter membrane at the bottom of the tank, enabling purification and concentration within a single container. The extract can be directly separated within the tank, removing small molecule impurities in real time while retaining and concentrating ergosterol in situ. This avoids losses and contamination caused by material transfer. Continuous impurity removal allows for more precise control of solution supersaturation, inducing ergosterol to form crystals with higher purity and more regular crystal forms, significantly improving the quality of the final product. It eliminates the need for a separate vacuum concentration unit, achieving heat-free physical concentration and reducing energy consumption. The integrated, three-dimensional system, achieved through a bottom agitation mechanism, further enhances the purification process. Stirring ensures separation efficiency and prevents membrane fouling. Through linkage and synchronization components, a single stirring motor drives the upper stirring blades and all bottom stirring blades to rotate synchronously, forming a three-dimensional stirring flow field from top to bottom. This ensures uniform material concentration and temperature within the tank. At the same time, it particularly enhances fluid flow on the surface of the filter membrane. The strong bottom stirring effectively washes the surface of the filter membrane, preventing the deposition of large molecules and pore blockage, thus ensuring the stability and long-term effectiveness of the membrane separation process. Using a single power source to drive multiple stirring elements simplifies the transmission structure and reduces manufacturing and maintenance costs.

[0025] The tank has a feed hopper fixedly connected to the top side of its outer surface and a discharge valve fixedly connected to the center of its bottom.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] (1) In this invention, the use of the crushing mechanism can achieve efficient and synergistic extraction, greatly improving efficiency and yield. By integrating the ultrasonic crushing generator and the microwave heating module into the same reaction vessel, the synergistic effect of physical crushing and thermal energy extraction is achieved. The ultrasonic wave uses the cavitation effect to instantly destroy the cell wall and release the contents. The microwave provides rapid and uniform internal heating, which greatly accelerates the mass transfer rate. The synergistic effect of the two shortens the extraction process of ergosterol from several hours to several minutes. The extraction efficiency is high and the time is short. At the same time, the degradation of active ingredients caused by long-term heating is avoided, resulting in a higher yield.

[0028] (2) In this invention, by using the discharge mechanism, the extraction section and the purification section can be seamlessly switched in the same device, realizing the integration of processes and the continuity of the process, greatly shortening the cycle, reducing material transfer loss and pollution risk. The multi-group linkage control components and limit design ensure process stability. Furthermore, the limit components of the discharge mechanism and the bottom stirring mechanism share the support structure, which greatly simplifies the overall design inside the tank, making the internal structure of the device compact, with high space utilization, and easy to manufacture and maintain.

[0029] (3) In this invention, the use of a filter membrane enables in-situ purification and concentration, achieving continuous process and quality improvement. A filter membrane is built into the bottom of the tank, enabling purification and concentration to be completed in the same container. The extract can be directly separated by membrane in the tank, small molecule impurities are removed in real time, and ergosterol is retained and concentrated in situ, avoiding loss and pollution caused by material transfer. By continuously removing impurities, the supersaturation of the solution can be controlled more precisely, inducing ergosterol to form crystals with higher purity and more regular crystal form, significantly improving the quality of the final product, eliminating the need for a separate vacuum concentration device, achieving physical concentration without heating, and reducing energy consumption.

[0030] (4) In this invention, the use of the bottom stirring mechanism enables integrated three-dimensional stirring, ensuring separation efficiency and preventing membrane fouling. Through the linkage and synchronization components, only one stirring motor is used to drive the upper stirring blade and all the bottom stirring blades to rotate synchronously, forming a three-dimensional stirring flow field from top to bottom, ensuring uniform material concentration and temperature in the tank. At the same time, the fluid flow on the surface of the filter membrane is particularly enhanced. The strong bottom stirring can effectively flush the surface of the filter membrane, prevent the deposition of large molecules and membrane pore blockage, and ensure the stability and long-term effectiveness of the membrane separation process. Using one power source to drive multiple stirring elements simplifies the transmission structure and reduces manufacturing and maintenance costs. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0041] Example 1, refer to Figure 1-8 An apparatus for preparing ergosterol in a functional beverage, comprising:

[0042] The top is equipped with a support column 1 for the tank body 7;

[0043] The crushing mechanism is located inside the tank 7. The crushing mechanism includes an agitating component, an ultrasonic crushing generator 17, and a microwave heating module 13. The ultrasonic crushing generator 17 is fixedly connected to the top of the tank 7, and the microwave heating module 13 is fixedly connected to the ultrasonic crushing generator 17 near the top. The agitating component is located inside the tank 7.

[0044] The discharge mechanism is located inside the tank body 7. The discharge mechanism includes a control component, a guide hopper 12 and a plug 21. The guide hopper 12 is fixedly connected inside the tank body 7, and the plug 21 is movably connected to the bottom of the guide hopper 12. The control component is provided in multiple sets, and the multiple sets of control components are equidistantly arranged inside the tank body 7, and the multiple sets of control components are all connected to the plug 21.

[0045] The filter membrane 5 is fixedly connected to the bottom of the tank 7 by a flow guiding and positioning ring 24, and the filter membrane 5 is fixedly connected inside the flow guiding and positioning ring 24; and

[0046] The bottom stirring mechanism is located inside the tank body 7.

[0047] In this implementation scheme: support column 1 supports tank 7; ultrasonic crushing generator 17 is equipped with a probe that can directly extend into the material inside tank 7 to generate cavitation effect, powerfully breaking down fungal cell walls; microwave heating module 13 uniformly introduces microwave energy into tank 7, selectively and rapidly heating the solvent and material internally; microwaves can rapidly raise the internal temperature of the material within seconds, significantly improving mass transfer efficiency; the synergistic effect of ultrasonic crushing generator 17 and microwave heating module 13 enables ergosterol to be efficiently extracted in a very short time; stirring components ensure uniform mixing of the material in the guide hopper. The bottom of 12 is controlled by the stopper 21 to control the material discharge from the top of the guide bucket 12. The pore size of the filter membrane 5 is selected to be sufficient to retain ergosterol molecules, but allows small molecule impurities to pass through. Small molecule impurities in the solution will be continuously removed through the membrane, while ergosterol is retained in the vessel, thereby achieving in-situ concentration and purification without heating. When the ergosterol concentration reaches the precise supersaturation point through membrane separation, nucleation and growth in the solution are induced. Since impurities are continuously removed, the supersaturation can be controlled very precisely. The top of the tank 7 is equipped with a pressure control component to control the pressure inside the tank 7.

[0048] Specifically: The agitating components include an agitator motor 18, a connecting rod 20, and an upper agitator blade 14. The connecting rod 20 is rotatably connected inside the tank body 7. The agitator motor 18 is fixedly connected to the top center of the tank body 7, and the output end of the agitator motor 18 is fixedly connected to the top of the connecting rod 20. The upper agitator blade 14 is fixedly connected to the connecting rod 20.

[0049] In this embodiment, the model of the stirring motor 18 can be selected from those available on the market as needed, which will not be elaborated here. The stirring motor 18 controls the connecting rod 20 to rotate, so that the upper stirring blade 14 can fully stir the solution at the top of the guide bucket 12 and complete the uniform mixing.

[0050] Specifically: Each set of control components includes a hinge seat 22, an opening and closing telescopic rod 11, and a limiting component. There are two hinge seats 22, one of which is fixedly connected to the tank body 7, and the other is fixedly connected to the plug 21. The two ends of the opening and closing telescopic rod 11 are respectively fixedly connected to the two hinge seats 22. The limiting component is located at the bottom of the plug 21, and the plug 21 is connected to the limiting component.

[0051] In this embodiment, the model of the telescopic rod 11 can be selected from those available on the market as needed, which will not be elaborated here. The height of the sealing plug 21 is adjusted by controlling the telescopic rod 11 to complete the opening and closing control of the bottom of the guide bucket 12. During the use of the telescopic rod 11, the hinge seat 22 can adjust the angle of the telescopic rod 11 accordingly so that the extension and retraction of the telescopic rod 11 is not affected by the angle.

[0052] Specifically: the limiting component is a limiting rod 10, which is fixedly connected to the bottom of the guide bucket 12, and the plug 21 is slidably connected to the limiting rod 10.

[0053] In this embodiment, the limiting rod 10 restricts the lifting path of the plug 21, so that the plug 21 can accurately extend and retract within the guide bucket 12.

[0054] Specifically: The bottom agitation mechanism includes:

[0055] The rotating components are provided in multiple sets, with each set of rotating components located at the bottom of each limiting rod 10;

[0056] Synchronization components are mounted on the rotating components; and

[0057] The linkage component is located on the connecting rod 20 and is connected to the rotating component.

[0058] In this embodiment, the rotating component, the synchronizing component, and the linkage component cooperate with each other to enable the connecting rod 20 to drive the bottom stirring mechanism.

[0059] Specifically: Each set of rotating parts includes a mounting frame 9, a bottom stirring rod 3 and a bottom stirring blade 6. The mounting frame 9 is fixedly connected to the bottom of the limiting rod 10, the bottom stirring rod 3 is rotatably connected to the mounting frame 9, and the bottom stirring blade 6 is fixedly connected to the bottom stirring rod 3.

[0060] In this embodiment: the bottom of the bottom stirring rod 3 is installed on the tank body 7, and the top of the bottom stirring rod 3 is installed on the mounting frame 9. The bottom stirring rod 3 controls the corresponding bottom stirring blade 6 to rotate, thereby completing the flow control of the broken solution.

[0061] Specifically: The synchronization component includes a synchronization gear 27 and a linkage gear ring 26. The bottom of multiple mounting brackets 9 are fixedly connected to mounting ring sleeves 8. Multiple synchronization gears 27 are provided, and each synchronization gear 27 is fixedly connected to the top of each bottom stirring rod 3. The linkage gear ring 26 is rotatably connected inside the mounting ring sleeve 8, and the linkage gear ring 26 meshes with multiple synchronization gears 27.

[0062] In this embodiment, the synchronous gear 27 and the linkage gear ring 26 cooperate with each other to realize the synchronous rotation of the bottom stirring rod 3.

[0063] Specifically: the linkage components include a timing belt 23, a drive gear 25, and a driven gear 28. A protective cover 4 is fixedly connected to the bottom of the tank body 7. The driven gear 28 is fixedly connected to the bottom of one of the bottom stirring rods 3. The drive gear 25 is fixedly connected to the bottom of the connecting rod 20. The timing belt 23 is installed inside the protective cover 4, and the timing belt 23 meshes with the drive gear 25 and the driven gear 28.

[0064] In this embodiment, the drive gear 25 and the driven gear 28 are the same size. The drive gear 25 and the driven gear 28 rotate synchronously through the synchronous belt 23, and the connecting rod 20 controls one of the bottom stirring rods 3 to rotate.

[0065] Specifically: A reagent inlet pipe 19 is fixedly connected to the bottom of the tank body 7, and multiple reagent nozzles 15 are equidistantly connected to the bottom of the reagent inlet pipe 19.

[0066] In this embodiment: the reagent inlet pipe 19 is connected to an external reagent device to realize reagent input, and multiple reagent nozzles 15 are evenly distributed to complete the uniform mixing of materials and reagents.

[0067] Specifically: a feed hopper 16 is fixedly connected to one side of the top of the outer surface of the tank body 7, and a discharge valve 2 is fixedly connected to the center of the bottom of the tank body 7.

[0068] In this embodiment: the feed hopper 16 facilitates the input of materials, and the feed hopper 16 can be sealed to ensure the sealing of the inside of the tank 7 and achieve stable internal air pressure. The discharge valve 2 discharges the impurities filtered by the filter membrane 5.

[0069] During use, ensure all components of the device are in good working order, with the discharge valve 2 closed. The plug 21 should tightly seal the bottom outlet of the guide hopper 12 under the action of the telescopic rod 11. Feed the dried fungal powder rich in ergosterol into the tank 7 through the feed hopper 16. Simultaneously, feed an appropriate amount of food-grade extraction solvent into the tank 7 through the reagent inlet pipe 19 and multiple reagent nozzles 15. The material and solvent should be positioned in the space above the guide hopper 12. Turn on the stirring motor 18, which will rotate the connecting rod 20 and the upper stirring blade 14 fixed thereon, mixing the material and solvent in the tank 7 to form a uniform slurry. Simultaneously, start the microwave heating... The heating module 13 and the ultrasonic crushing generator 17 are used. The microwave heating module 13 provides rapid and uniform internal heating to the slurry, greatly improving mass transfer efficiency. The cavitation effect generated by the ultrasonic crushing generator 17 powerfully breaks down the fungal cell walls, releasing intracellular ergosterol. The synergistic effect of microwave and ultrasound allows ergosterol to be efficiently extracted into the solvent in a very short time. After crushing, all the opening and closing telescopic rods 11 are controlled to extend and retract. Through the linkage of the hinge seat 22, the stopper 21 is pulled down along the limiting rod 10, opening the outlet at the bottom of the guide bucket 12. The crushed material solution flows out through the outlet at the bottom of the guide bucket 12 under the action of gravity. Inside the tank 7, at the bottom, the rotation of connecting rod 20 transmits power to one of the bottom stirring rods 3 via the drive gear 25, synchronous belt 23, and driven gear 28 at its bottom. The rotation of this bottom stirring rod 3, through the meshing of the synchronous gear 27 at the top and the linkage gear ring 26, drives all the bottom stirring rods 3 and their bottom stirring blades 6 to rotate synchronously, ensuring that the solution near the filter membrane 5 in the tank 7 flows sufficiently and evenly. Simultaneously, small molecule impurities in the solution, under the influence of pressure and concentration difference, pass through the micropores of the filter membrane 5 and enter the bottom of the tank 7. Ergosterol molecules trapped by the filter membrane 5 remain in the filter membrane. In the solution above the filter membrane 5, in-situ concentration and purification without heating are achieved. Impurities and waste liquid that have permeated to the bottom of the tank 7 during the purification process are periodically discharged through the discharge valve 2. When the purification and concentration meet the requirements, the stirring motor 18 is stopped, and the purified and concentrated solution or slurry rich in high-purity ergosterol is taken out to complete the preparation. After completion, the cleaning solvent is introduced, the stirring mechanism is started, and the inside of the tank 7, the stirring blades, and the filter membrane 5 are cleaned. After cleaning, the discharge valve 2 is closed, and the opening and closing telescopic rod 11 is operated to lift the plug 21 and reseal the bottom of the guide bucket 12 to prepare for the next preparation.
