Description

Technical Field

[0001] The invention relates to the technical field of food oil processing and traditional Chinese medicine herbal products, and in particular to an integrated device and process for low-temperature slow extraction of olive oil as a herbal raw material. Background Art

[0002] Olive oil is a woody plant oil that is directly cold-pressed from fresh olive fruits. It retains its natural nutrients without being heated or chemically treated. Olive oil is considered to be the most suitable oil for human nutrition discovered so far. Herbal olive oil refers to herbs soaked in olive oil for several weeks or longer, allowing the herbs to release fat-soluble active ingredients that dissolve in the olive oil.

[0003] The integrated device and process for low-temperature slow extraction of herbal olive oil solves the problems of active ingredient loss and low efficiency in traditional olive oil production through integrated design and precise temperature control, and is an important direction for the upgrading of the olive oil industry.

[0004] However, the existing integrated device and process for low-temperature slow extraction of herbal olive oil has the following shortcomings: Existing integrated low-temperature slow extraction devices for herbal raw material olive oil usually use mechanical stirring shafts and sealing devices. Long-term operation will cause wear of transmission parts such as bearings. Such metal debris may contaminate the extract, thereby causing unnecessary economic losses. In addition, high-speed mechanical stirring will generate strong eddy currents and shear forces, thereby destroying the molecular structure of heat-sensitive components. Traditional stirring may form local high temperatures or stratification, resulting in insufficient contact between the raw materials and the solvent and a decrease in the extraction rate. At the same time, the ground material needs to be transferred to the reaction tank through a pipeline or container. The exposure in the intermediate link will be exposed to too much oxygen, resulting in an increase in the peroxide value.

[0005] Therefore, we proposed an integrated device and process for low-temperature slow extraction of herbal raw material olive oil in order to solve the above problems. Summary of the Invention

[0022] In the embodiments of the present invention, please refer to the attached Figure 1 -Attached Figure 3 As shown, the present invention provides a technical solution: an integrated device for low-temperature slow extraction of herbal raw material olive oil, comprising a magnetic levitation micro-disturbance component 600, a lifting type grinding pretreatment component 700, and four supporting legs 100. The tops of the four supporting legs 100 are respectively provided with a magnetic levitation micro-disturbance component 600 and a lifting type grinding pretreatment component 700.

The lifting type grinding pretreatment component 700 can grind and crush the raw materials to be extracted in advance, and the ground materials can pass through the electric ball valve 800 directly through the top cover 611 and fall into the inner tank 605.

[0023] Specifically: first, the four legs 100 can provide effective support for the above-mentioned connected components. When the raw materials need to be ground and crushed, the raw materials to be ground and crushed are poured into the groove 709 inside the lower plate 708. After the raw materials are ground and crushed under the action of the grinding parts 707, they pass through the electric ball valve 800 and directly through the top cover 611 into the inner tank 605. Then, the rotating magnetic field generated by the electromagnetic coil 603 drives the permanent magnet 610 array.

[0024] In some embodiments, according to Figures 1-6As shown, the magnetic levitation micro-perturbation component 600 includes a group of electromagnetic coils 603 and a group of permanent magnets 610. The group of electromagnetic coils 603 is used to generate a rotating magnetic field, and the group of permanent magnets 610 is used to generate three-dimensional micro-swings. The group of permanent magnets 610 is arranged in a planar radial pattern and is distributed in a stepped manner at three heights.

[0026] An inner tank 605 is installed between the inner surfaces of the outer tank 601, and there is a circle of movable space between the outer tank 601 and the inner tank 605. The top and bottom of the outer tank 601 and the inner tank 605 are fixedly connected with a top cover 611 and a bottom cover 609. The outer surface of the inner tank 605 is wrapped with a coil 604, the top of the top cover 611 is connected to a feed pipe 612, the outer surface of the outer tank 601 is connected to a vacuum pipe, the top of the bottom cover 609 is embedded and connected to the bottom of a group of permanent magnets 610, and the top of the top cover 611 is connected to the bottom of the electric ball valve 800.

[0027] A circulation pump 606 is fixedly installed on the outer surface of the annular fixed sleeve 602. The top and bottom of the circulation pump 606 are respectively connected to a liquid outlet pipe 607 and a liquid inlet pipe 608. One end of the outer wall of the liquid outlet pipe 607 and the liquid inlet pipe 608 is respectively connected to the liquid outlet end and the liquid inlet end of the coil 604.

[0028] The top of the bottom cover 609 is connected to four brackets 617 , and the tops of the four brackets 617 are bolted to a guide tube 615 . The outer surface of the guide tube 615 is provided with a spiral guide groove, and the guide groove is used to guide the fluid.

[0029] Four flow-disturbing blades 616 are fixedly installed on the inner surface of the guide tube 615, and the four flow-disturbing blades 616 are used to disrupt the flow direction of the fluid. A vacuum pump 613 is fixedly installed on one side of the outer surface of the outer tank 601, and a pipe interface 614 is connected to one side of the outer wall of the vacuum pump 613, and the pipe interface 614 is connected to the vacuum pipe.

[0030] The vacuum pump 613 is installed on one side of the outer wall of one of the support frames 200 , the bottom of the bottom cover 609 is connected to the top of the discharge port 900 , and the outer surface of the outer tank 601 is connected to one end of the outer wall of the four cross braces 300 .

[0031] The effect achieved by the entire embodiment is as follows: through the above components, a complete magnetic levitation micro-disturbance component 600 is formed. First, the raw materials to be extracted are ground and crushed in advance by the lifting grinding pretreatment component 700. At the same time, the ground materials can pass through the electric ball valve 800 and directly fall into the inner tank 605 through the top cover 611. When all the ground materials enter the inner tank 605, an oxygen content sensor is first installed in the inner tank 605 for detection. Secondly, a PLC control system is installed on the outer wall of the outer tank 601 to control the start of the vacuum pump 613 to control the oxygen content in the inner tank 605 to be lower than 5%, thereby avoiding oxidation reaction. Causes degradation of components, and secondly, a temperature controller is installed inside the inner tank 605. Secondly, the PLC control system starts the heating system through the temperature controller, and the coil 604 between the outer tank 601 and the inner tank 605 is injected with hot water through the circulation pump 606 to adjust the water temperature and flow rate so that the temperature inside the inner tank 605 is stabilized at the target value. The temperature controller is used to monitor the inner layer temperature to form a closed-loop control. At this time, a group of electromagnetic coils 603 outside the outer tank 601 are energized to generate a rotating magnetic field with adjustable frequency. This rotating magnetic field prompts a group of permanent magnets 610 arrays on the plane of the tank bottom to be radially arranged. The external group of electromagnetic coils 603 generates a rotating magnetic field through alternating current. The permanent magnet array 610 rotates due to the force of the magnetic poles, driving the fluid in the tank to form a macro vortex. Since the permanent magnets 610 are arranged in a planar radial pattern and are distributed in three heights in a stepped manner, the stepped distribution with low middle and high outer heights can reduce the edge effect of the magnetic field vortex and avoid local stagnation of the fluid. The fluid is driven to rotate by the magnetic field, thereby driving the solvent and raw material particles in the inner tank 605 to generate a macro vortex. Secondly, the outer surface of the guide tube 615 is provided with a spiral guide groove. The spiral rising guide groove on the outer surface of the guide tube 615 will guide the fluid to rise along the spiral path to form a stable cycle. The four spoiler blades 616 on the inner surface of the guide tube 615 can Break the laminar flow, enhance the turbulence, and promote uniform contact between the solvent and the raw material, thereby avoiding local overheating or precipitation. The eddy currents generated by a group of electromagnetic coils 603 and a group of permanent magnets 610 work together with the turbulence of the four spoiler blades 616 to suspend the raw material particles and continue to roll, thereby increasing the solvent penetration efficiency. When the preset extraction time is reached, a group of electromagnetic coils 603 stops the rotating magnetic field, and a group of permanent magnets 610 array is stationary. At this time, the extracted particles inside the inner tank 605 settle to the bottom of the inner tank 605. At this time, the discharge valve of the bottom cover 609 is opened, and the extracted particles inside the inner tank 605 are discharged through the discharge port 900.

[0032] The magnetic levitation micro-perturbation component 600, the rotating magnetic field generated by the electromagnetic coil 603 drives the permanent magnet 610 array, without the need for mechanical shaft connection, which can avoid friction and seal wear, thereby reducing maintenance costs, and preventing metal debris from contaminating the extract. The permanent magnet 610 array is arranged radially, so that the fluid inside the inner tank 605 circulates synchronously in the radial and axial directions to form a multi-directional mixed flow field. This low-speed stirring can reduce the heat and oxidation generated by violent movement, and avoid the occurrence of local high temperature caused by mechanical friction. Under low temperature conditions, the fluid viscosity is high, and traditional mechanical stirring is prone to uneven eddy currents or stratification. The magnetic levitation micro-perturbation maintains uniform mixing through low-speed, continuous disturbances.

[0033] according to Figure 1-Figure 3 as well as Figure 7-Figure 8 As shown, the lifting grinding pretreatment component 700 includes an upper plate 706, the bottom of which is fixedly connected to a grinding piece 707, a lower plate 708 is installed at the bottom of the upper plate 706, a groove 709 is opened inside the lower plate 708, and the grinding piece 707 and the groove 709 are engaged with each other.

[0034] The lifting grinding pretreatment component 700 also includes a fixed plate 701, on the top of which an electric cylinder 702 is fixedly mounted. The shaft end of the electric cylinder 702 is fixedly sleeved with an L-shaped plate 703, and a servo motor 704 is fixedly mounted on one side of the outer wall of the L-shaped plate 703.

[0035] The shaft end of the servo motor 704 is rotatably connected to a metal connecting plate 705, the bottom of the metal connecting plate 705 is connected to the top bolt of the upper plate 706, the bottom of the fixed plate 701 is connected to the top bolt of the connecting piece 500, the outer surface of the lower plate 708 is connected to one side of the outer wall of the four support frames 200, the bottom of the upper plate 706 is connected to the top bolt of the grinding piece 707, and the bottom of the lower plate 708 is connected to the top of the electric ball valve 800.

[0036] The effect achieved by the entire embodiment is as follows: through the above components, a complete lifting grinding pre-treatment component 700 is formed. First, the equipment is connected to an external power supply. Secondly, the electric cylinder 702 is started by the external power supply. The electric cylinder 702 can convert electrical energy into mechanical energy to drive the servo motor 704 and the connected components to make linear motion, thereby raising the upper plate 706 at the bottom to the top. At this time, the staff pours the raw materials into the groove 709 inside the lower plate 708. At this time, the electric cylinder 702 is started again. According to the preset parameters, the electric cylinder 702 can convert electrical energy into mechanical energy to drive the servo motor 704 and the connected components. It makes linear motion. When the grinding piece 707 is fully engaged with the groove 709, the servo motor 704 drives the upper plate 706 to rotate at high speed and engage with the groove 709, forming a shearing and extrusion grinding effect. The grinding pressure is monitored by the pressure sensor installed inside the grinding piece 707. If the current hardness of the raw material is too high, the electric cylinder 702 drives the connected components to reduce the distance between the upper plate 706 and the lower plate 708 to increase the pressure. If the raw material is soft, the distance is increased to avoid excessive crushing. When the grinding is completed, the electric ball valve 800 is opened, and the fine particles after grinding fall into the inner tank 605 under the action of gravity.

[0037] The lifting grinding pretreatment component 700 uses the electric cylinder 702 to adjust the gap between the upper plate 706 and the lower plate 708 in real time, and matches the grinding pressure according to the hardness of the raw material and the required particle size, which can avoid insufficient grinding of hard raw materials or excessive crushing of soft raw materials. At the same time, the ground material falls directly into the inner tank 605, which can eliminate the intermediate storage or transmission steps, thereby reducing the risk of material contamination, and can reduce the equipment footprint, realize an integrated design, and thus improve production efficiency.

[0038] according to Figure 1-Figure 3 As shown, a group of four support legs 100 are connected to four support frames 200 by top bolts, and a cross brace 300 is welded to one side of the outer wall of each of the four support frames 200. The top bolts of the four support frames 200 are connected to a support platform 400, and the top bolts of the support platform 400 are connected to a connecting piece 500. The bottom of the connecting piece 500 is respectively provided with an electric ball valve 800 and a discharge port 900.

[0039] The effect achieved by the entire embodiment is as follows: first, determine the specific installation position of the four legs 100, then move the entire device to the area where it is to be installed, then contact the four legs 100 with the ground and fully fix the four legs 100 to the ground, after the four legs 100 are fixed, connect the external power supply to the device to be powered, then bolt the tops of the four legs 100 to the four support frames 200, and weld the cross braces 300 on one side of the outer wall of the four support frames 200, then bolt the tops of the four support frames 200 to the ground. The four support frames 200 are connected to the support platform 400, and the connecting piece 500 is bolted to the top of the support platform 400. The four support frames 200 can provide effective vertical support force for the components connected thereto. Secondly, the cross brace 300 can provide lateral support force, and the support platform 400 on the top of the four support frames 200 can provide bearing capacity for the electric cylinder 702, the servo motor 704, the upper plate 706 and the grinding piece 707, so as to ensure that the lifting type grinding pretreatment component 700 provides sufficient support force when grinding the raw materials, so as to ensure the normal progress of subsequent production.

[0040] The working principle of the whole equipment is as follows: during the grinding stage, first connect the equipment to an external power supply, then start the electric cylinder 702 through the external power supply, the electric cylinder 702 can convert electrical energy into mechanical energy to drive the servo motor 704 and the connected parts to do linear motion, thereby raising the upper plate 706 at the bottom to the top, at this time the staff pours the raw materials into the groove 709 inside the lower plate 708, at this time start the electric cylinder 702 again, the electric cylinder 702 can convert electrical energy into mechanical energy according to the preset parameters to drive the servo motor 704 and the connected parts to do linear motion, when the grinding piece 70 7 fully meshes with the groove 709. At this time, the servo motor 704 drives the upper plate 706 to rotate at high speed and mesh with the groove 709, forming a shearing and extrusion grinding effect. The grinding pressure is monitored by the pressure sensor installed inside the grinding member 707. If the current hardness of the raw material is too high, the electric cylinder 702 drives the connected components to reduce the distance between the upper plate 706 and the lower plate 708 to increase the pressure. If the raw material is soft, the distance is increased to avoid excessive crushing. When the grinding is completed, the electric ball valve 800 is opened, and the ground fine particles fall into the inner tank 605 under the action of gravity.

[0041] During the extraction stage, the ground material can pass through the electric ball valve 800 and directly fall into the inner tank 605 through the top cover 611. When all the ground materials enter the inner tank 605, first, an oxygen content sensor is installed in the inner tank 605 for detection. Then, a PLC control system installed on the outer wall of the outer tank 601 controls the start of the vacuum pump 613 to control the oxygen content in the inner tank 605 to be lower than 5% to avoid degradation of the components caused by oxidation reaction. Then, a temperature controller is installed in the inner tank 605. Then, the PLC control system starts the heating system through the temperature controller. The outer tank 601 and the inner tank The coil 604 between the tanks 605 is injected with hot water through a circulation pump 606, and the water temperature and flow rate are adjusted to stabilize the temperature inside the inner tank 605 at the target value. The inner temperature is monitored by a thermostat to form a closed-loop control. At this time, a set of electromagnetic coils 603 outside the outer tank 601 are energized to generate a rotating magnetic field with adjustable frequency. This rotating magnetic field prompts a set of permanent magnet arrays 610 radially arranged on the bottom plane of the tank. The external set of electromagnetic coils 603 generates a rotating magnetic field through alternating current. The set of permanent magnet arrays 610 rotates due to the force exerted on the magnetic poles, driving the fluid in the tank to form macroscopic eddy currents. The permanent magnets 610 are arranged in a radial plane and are distributed in a stepped manner at three heights. The stepped distribution with the middle low and the outer high can reduce the edge effect of the magnetic field eddy current, avoid local stagnation of the fluid, and rotate under the drive of the magnetic field, thereby driving the solvent in the inner tank 605 and the raw material particles to generate macroscopic eddy currents. Secondly, the outer surface of the guide tube 615 is provided with a spiral guide groove. The spiral rising guide groove on the outer surface of the guide tube 615 will guide the fluid to rise along the spiral path to form a stable cycle. The four spoiler blades 616 on the inner surface of the guide tube 615 can break the laminar flow, enhance the turbulence, and promote the solvent and raw material particles to form a stable cycle. The eddy currents generated by a set of electromagnetic coils 603 and a set of permanent magnets 610 work together with the turbulence of the four spoiler blades 616 to suspend the raw material particles and continue to roll, thereby increasing the solvent penetration efficiency. When the preset extraction time is reached, a set of electromagnetic coils 603 stops rotating the magnetic field, and a set of permanent magnet arrays 610 is stationary. At this time, the extracted particles inside the inner tank 605 settle to the bottom of the inner tank 605. At this time, the discharge valve of the bottom cover 609 is opened, and the extracted particles inside the inner tank 605 are discharged through the discharge port 900.

[0042] Specifically: when Chinese medicinal herbs need to be ground and crushed, the ground and crushed Chinese medicinal herbs are poured into the groove 709 inside the lower plate 708, so that the grinding piece 707 is fully engaged with the groove 709, and the servo motor 704 is used to drive the upper plate 706 to rotate at high speed to form a shearing and squeezing grinding effect with the groove 709. When the grinding is completed, the electric ball valve 800 is opened, and the fine particles after grinding fall into the inner tank 605 under the action of gravity, and the PLC control system is started at the same time to calibrate and initialize various sensors such as the oxygen content sensor and the temperature controller inside the inner tank 605.

[0043] During the static constant temperature slow extraction stage, the ground Chinese medicinal herbs enter the inner tank 605 through the electric ball valve 800 under the action of gravity, and olive oil is added. At this time, the thermostat can monitor the temperature inside the inner tank 605 in real time. When the thermostat detects that the temperature inside the inner tank 605 is lower than the set temperature of 30-42°C, the circulation pump 606 is started by an external power supply. The circulation pump 606 will draw external hot water source and transport the hot water source to the coil 604 through the liquid inlet pipe 608, and the circulated hot water is transported to the circulation pump 606 through the liquid outlet pipe 607, so that the temperature inside the inner tank 605 is stabilized at the target value and is left to stand for 21 days to allow it to naturally infiltrate and release the initial components.

[0044] During the intermittent stirring and slow extraction phase, the timing module of the PLC control system is first set to activate the magnetic levitation micro-perturbation assembly 600 once every 12 hours, gently stirring the Chinese herbs and olive oil inside the inner tank 605 for three minutes. At this time, a set of electromagnetic coils 603 on the outside of the outer tank 601 is energized, generating a rotating magnetic field with an adjustable frequency. This rotating magnetic field drives a radial array of permanent magnets 610 on the bottom of the tank. The external set of electromagnetic coils 603 generates a rotating magnetic field through alternating current. The magnetic poles of the array of permanent magnets 610 rotate due to the force applied to them, driving the fluid in the tank to form macroscopic eddy currents. Because the array of permanent magnets 610 is arranged radially in a plane and arranged in a stepped manner at three heights (with a low center and a high outer height), the stepped arrangement reduces the edge effects of the magnetic field eddy currents and prevents local stagnation of the fluid. Driven by the magnetic field, the fluid rotates, thereby gently stirring the Chinese herbs and olive oil in the inner tank 605. This process is continued for up to 60 days to enhance homogeneity and fully release the active ingredients.

[0045] To control the oxygen content, first, the real-time oxygen content data inside the inner tank 605 is transmitted to the PLC control system through the oxygen content sensor. When the oxygen content inside the inner tank 605 is higher than 5%, the vacuum pump 613 is started by an external power supply. At this time, the vacuum pump 613 can extract the oxygen inside the inner tank 605 through the pipeline, and control the oxygen content inside the inner tank 605 to be lower than 5%, so as to inhibit the degradation of easily oxidized components, thereby ensuring the stability of the herbal volatile substances and oil quality. Specific implementation method: For the pretreatment of Ganoderma lucidum raw materials, mature red Ganoderma lucidum fruiting bodies are selected and dried naturally in a combination of natural sun drying and low-temperature drying (40°C) to a moisture content of ≤8%. They are then broken into 2-5 mm fragments using the lifting grinding pretreatment component 700 and then gently baked (45-50°C, 4-6 hours) to stimulate cell wall activity.

[0047] The Ganoderma lucidum extraction process is to mix Ganoderma lucidum with extra virgin olive oil at a weight ratio of 1:5-1:8 by weight, place the mixture in an inner tank 605, and first let it soak at 30-42°C for 30 days. The magnetic levitation micro-perturbation component 600 is activated once every 12 hours and stirred for 3 minutes to promote the dissolution of fat-soluble components such as triterpenes and polysaccharides. The low-temperature slow extraction is continued for up to 81 days. During this period, the temperature is circulated and controlled by the coil 604, and the vacuum pump 613 is used to maintain the oxygen content ≤5%, ultimately achieving deep fusion of the oil body and the active ingredients.

[0048] Pretreatment of Gastrodia elata raw materials: roughly cut the Gastrodia elata tubers into 1-2 cm thick slices and place them in a hot air circulation oven for light baking (40-45°C, 4 hours) to reduce moisture and activate the gastrodin precursor.

[0049] In the gastrodia elata extraction process, gastrodia elata and olive oil are mixed in a ratio of 1:6-1:7, and low-temperature slow extraction is started at 30-40°C. Volatile oil components are released by static infiltration for the first 21 days. During this period, the low-frequency magnetic field generated by the electromagnetic coil 603 drives the permanent magnet 610 to cause micro-perturbations every day. Subsequently, slow extraction is continued for 81 days. The spiral guide groove of the guide tube 615 is used to guide fluid circulation, stabilize the active ingredients of gastrodia glycosides, and avoid high-temperature degradation.

[0050] Cordyceps raw material pretreatment: After the mycelium of Cordyceps sinensis is sliced, it is dried with hot air at 45°C until the moisture content is ≤10%. The mycelium is broken into powder by the shearing action of the grinding piece 707 and the groove 709.

[0051] In the cordyceps extraction process, the powder and olive oil are mixed in a ratio of 1:7 and slowly extracted at a low temperature of 30-40°C. During the first 40 days, the stepped permanent magnet 610 array of the magnetic levitation micro-perturbation component 600 generates a three-dimensional eddy current to promote the release of cordycepin, alkaloids, ergosterol and other components. Subsequently, the slow extraction is continued for 81 days. The hot water flow of the circulation pump 606 is adjusted by the PLC control system to maintain the temperature fluctuation of the inner tank 605 ≤±1°C to complete the alcoholization reaction in the oil.

[0052] For the pretreatment of angelica raw materials, select angelica from authentic production areas, first dry it in the shade until the moisture content is ≤12%, then cut it into 0.5 cm thick slices, and lightly roast it at low temperature (40-45℃) to remove some volatile oil impurities and retain the active ingredients.

[0053] The angelica extraction process involves mixing angelica and olive oil in a ratio of 1:5-1:6. The mixture is first soaked in a 30-42°C environment for 25 days. Turbulator blades 616 are used to disrupt laminar flow and promote component dissolution. Slow extraction is then continued for 81 days. During this period, a vacuum pump 613 is activated every 48 hours to maintain an oxygen content of ≤3%. Combined with water temperature control in the coil 604, the oil's aroma and color are stabilized to prevent oxidative browning.

[0054] Ginseng raw materials are pre-treated. Five-year-old sun-dried ginseng is baked (45-50°C) to soften and then chopped into 2-3 mm thin slices. The electric cylinder 702 is used to adjust the distance between the upper plate 706 and the lower plate 708, and the grinding pressure is controlled to 0.3-0.5 MPa to form uniform particles.

[0055] In the ginseng extraction process, ginseng slices and olive oil are mixed in a ratio of 1:8 and placed in an environment of 37-41°C. For the first 35 days, the adjustable frequency magnetic field of the electromagnetic coil 603 drives the permanent magnet 610 to rotate, promoting the release of the fat-soluble segment of the saponin. Subsequently, the extraction is slowed down to 81 days, and the spiral upward flow field of the guide tube 615 promotes particle suspension.

[0056] The mulberry leaves and wolfberry raw materials are pretreated by first drying the mulberry leaves in the shade until the moisture content is ≤10% and then lightly roasting them at 40-45°C. The wolfberries are low-temperature dried at 35-40°C and then mixed and crushed by the lifting grinding pretreatment component 700.

[0057] In the mulberry leaf and wolfberry extraction process, the total amount of herbs is mixed with olive oil in a ratio of 1:10, and low-temperature slow extraction is started at 30-40°C for 9 days. Low-speed stirring is performed daily through the magnetic levitation micro-perturbation component 600 to promote the release of antioxidant ingredients.

[0060] The raw materials of the dang ginseng and astragalus are pretreated. The dang ginseng and astragalus are sliced ​​and dried to a moisture content of ≤10%. The slices are then processed through a lifting grinding pretreatment component 700 to form 2-4 mm particles.

[0061] The extraction process of Codonopsis pilosula and Astragalus membranaceus is mixed with olive oil in a ratio of 1:10, and slowly extracted for 12 days at 30-40°C. The turbulence is enhanced by the turbulent blades 616 of the guide tube 615 to promote the dissolution of saponins and immune-enhancing ingredients.

[0062] The lily and platycodon grandiflorum raw materials are pre-processed. The lily is lightly baked to prevent moisture, and the platycodon grandiflorum is sliced ​​and lightly roasted to enhance the aroma. The two are mixed and then ground into particles by the lifting grinding pre-processing component 700.

[0063] The lily and platycodon grandiflorum extraction process is to mix them with olive oil in a ratio of 1:10 and slowly extract them at 30-40°C for 9 days. The stepped permanent magnet 610 of the magnetic levitation micro-perturbation component 600 is arranged to form a radial and axial mixed flow field, thereby extracting lung-moistening and cough-relieving ingredients.
