Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine preparation machine technology, and more specifically, to a decoction preparation machine and preparation process for improving spleen metabolism and promoting diuresis. Background Technology

[0002] Metabolic dysfunction-associated fatty liver disease (MAFLD) has become the most common chronic liver disease worldwide. Currently, there is no effective Western medicine. Traditional Chinese medicine has unique advantages in regulating metabolism as a whole. Classic formulas such as the "dampness-removing and spleen-benefiting" formula (which often contains Alisma plantago-aquatica, Atractylodes macrocephala, Poria cocos, etc.) have shown the potential to improve liver lipid metabolism in clinical practice.

[0003] However, the existing traditional methods for preparing Chinese herbal decoctions have obvious defects: different medicinal materials have different optimal dissolution conditions (for example, the effective components of Danshen and Gegen need to be fully soaked and moderately heated, while the organic acids of raw hawthorn are easily destroyed under long-term high temperature). The traditional one-pot decoction method cannot achieve differentiated processing, resulting in insufficient extraction or destruction of some components, which affects the efficacy of the decoction in promoting diuresis, benefiting the spleen and improving metabolism.

[0004] Therefore, the present invention designs a preparation device that performs gradient treatment based on the characteristics of medicinal materials and can ensure the efficient and stable dissolution of active ingredients, which is of great importance for promoting the modernization and standardization of this traditional Chinese medicine composition.

[0015] A process for preparing a decoction to promote diuresis, benefit the spleen, and improve metabolism includes selecting the following raw materials in parts by weight: 12-18 parts of Alisma plantago-aquatica, 5-10 parts of Atractylodes macrocephala, 12-18 parts of Poria cocos, 8-12 parts of Salvia miltiorrhiza, 8-12 parts of Pueraria lobata, and 10-15 parts of raw Crataegus pinnatifida. The steps are as follows: S1. Rinse and drain Alisma plantago-aquatica and Poria cocos; wash Atractylodes macrocephala, Salvia miltiorrhiza and Pueraria lobata and soak them in 30℃ drinking water for 30 minutes; wash raw hawthorn and then lightly break it up with a high-speed blender. S2. Load Atractylodes macrocephala and hawthorn into the first feeding chamber of the equipment, and load Alisma plantago-aquatica, Poria cocos, Salvia miltiorrhiza and Pueraria lobata into the second feeding chamber. Close the feeding pipe and set the extraction program through the controller, that is, open the second feeding chamber in the first decoction stage and open the first feeding chamber in the second decoction stage. S3. The water supply equipment adds drinking water to the extraction tank through the water supply pipe. The program starts: the first feeding chamber is closed, only the second feeding chamber is opened, the stirrer is started and stirred at a low speed of 20r / min, the heating resistance wire is started and the temperature is raised according to the preset program, that is, from 25℃ to 68℃ in 15 minutes, maintained for 8 minutes, and then raised to 102℃ in 8 minutes. When the temperature reaches 100-105℃, the pressurized gas source maintains the pressure in the extraction tank at 0.08-0.12MPa through the pressurized pipe (4). Under this condition, it is boiled for 40 minutes. After the time is up, the pressure is reduced, the first decoction is collected through the liquid outlet pipe, and filtered through the three-stage filter to obtain the first decoction filtrate. S4. Add hot water to the dregs in the tank through the water supply pipe. Open the first feeding chamber with the controller to let the Chinese medicinal materials fall into the tank. Simmer for 30 minutes at normal pressure and 90-95℃. After the decoction is finished, collect the second decoction, filter it to obtain the second decoction filtrate. S5. Combine the first and second decoction filtrates to obtain a decoction that promotes diuresis, benefits the spleen, and improves metabolism.

[0016] The advantages of this invention are: Firstly, this invention allows for differentiated feeding based on the different textures of various medicinal materials, thereby optimizing the extraction of active ingredients from medicinal materials with different properties, improving the total dissolution rate and stability of the effective components, and ensuring the efficacy of the decoction after preparation by promoting diuresis, benefiting the spleen, and improving metabolism.

[0017] Secondly, this invention incorporates a stirring mechanism, and the stirring shaft can be controlled to move up and down during rotation. As the stirring shaft rises, it can scoop up the medicinal materials at the bottom of the extraction tank, forcibly lifting them to the upper liquid or even gas phase. As the stirring shaft descends, the medicinal materials on the stirring plate are scattered back down. This achieves a three-dimensional circulation throughout the entire tank, ensuring that each portion of the medicinal materials periodically travels the complete path from the high-temperature, high-pressure bottom of the tank to the relatively low-temperature liquid surface. It also better mixes the new and old medicinal materials evenly, greatly increasing the contact probability between the new and old medicinal materials and the solvent, resulting in a more thorough and uniform extraction.

[0018] Thirdly, by setting up structures such as a shaking plate, the present invention can quickly shake the medicinal materials on the stirring plate when the stirring shaft moves downward, so that they are evenly scattered in the medicinal liquid. At the same time, the high-concentration extract film attached to the surface of the medicinal materials is "torn off" under the action of shaking force, and the fresh, low-concentration solvent quickly wets the surface of the medicinal materials when they fall back, which significantly enhances the diffusion driving force of concentration difference and accelerates the migration rate of active ingredients from the inside of the medicinal materials to the solvent.

[0022] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0023] In this invention, unless otherwise stated, the directional terms such as "up" and "down" generally refer to the directions shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0024] Please see Figure 1-10 The present invention provides the following technical solutions: Specifically, it refers to a decoction preparation machine for improving spleen function and metabolism by promoting diuresis and eliminating dampness, including an extraction tank 1. A feeding pipe 2 is fixedly connected to the end cap of the extraction tank 1, with its lower end penetrating into the extraction tank 1. A water supply pipe 3 and a pressure pipe 4 are fixedly connected to the end cap of the extraction tank 1. The other end of the water supply pipe 3 is connected to a water supply device, and the other end of the pressure pipe 4 is connected to a pressure device. A pressure sensor 5 for detecting the pressure inside the extraction tank 1 is fixedly connected to the end cap of the extraction tank 1. A thermometer sleeve 6 is fixedly connected to the end cap of the extraction tank 1. The lower end of the thermometer sleeve 6 penetrates into the extraction tank 1, thus it is used to detect the temperature change inside the extraction tank 1. A heating resistance wire 9 is embedded in the inner wall of the extraction tank 1. A liquid outlet pipe 10 is fixedly connected to the lower surface of the extraction tank 1. A solenoid valve is installed on the outer surface of the liquid outlet pipe 10. A filter screen 101 is fixedly connected to the inner wall of the liquid outlet pipe 10 near the extraction tank 1. A controller is installed on the extraction tank 1. The controller is electrically connected to the water supply equipment, pressurization equipment, pressure sensor 5, thermometer sleeve 6, solenoid valve and heating resistance wire 9 respectively.

[0025] Furthermore, the feeding pipe 2 is equipped with a cover plate structure for sealing, and the extraction tank 1 is equipped with a stirring mechanism for stirring. A partition plate 28 is fixedly connected between the inner walls of opposite sides of the feeding pipe 2, dividing the feeding pipe 2 into a first feeding chamber and a second feeding chamber. The lower side of the partition plate 28 extends out of the lower surface of the feeding pipe 2, and two feeding baffles 29 are provided on the opposite sides of the lower side of the partition plate 28. The two feeding baffles 29 respectively block the lower side of the first feeding chamber and the lower side of the second feeding chamber. A rotating groove 210 is opened on the side of the partition plate 28 facing the feeding baffles 29, and the rotating groove 210 is located on opposite sides. A rotating shaft 211 is rotatably connected between the inner walls. A rotating block 212 is fixedly connected to the side of the feeding baffle 29 near the rotating groove 210. The other side of the rotating block 212 extends into the rotating groove 210 and is fixedly sleeved on the outer surface of the rotating shaft 211. A control cavity 213 is opened inside the partition plate 28 near the rotating groove 210. A micro motor 214 is fixedly connected to the bottom wall of the control cavity 213. The micro motor 214 is a GW370 worm gear reducer motor. The end of the rotating shaft 211 near the control cavity 213 rotates through the control cavity 213 and is fixedly connected to the output shaft of the micro motor 214.

[0026] In use, Atractylodes macrocephala and hawthorn can be put into the first feeding chamber, while Alisma plantago-aquatica, Poria cocos, Salvia miltiorrhiza, and Pueraria lobata can be put into the second feeding chamber. After feeding, the feeding pipe 2 is closed by the cover plate structure. At different stages, the micro motor 214 at the corresponding position is started, so that the output shaft of the micro motor 214 drives the rotating shaft 211 to rotate, thereby driving the feeding baffle 29 to rotate downward, no longer blocking the first or second feeding chamber, so that the medicinal materials in the corresponding feeding chamber fall into the extraction tank 1. Thus, the feeding can be differentiated according to the differences in the texture of different medicinal materials, realizing the optimized extraction of active ingredients of medicinal materials with different properties, improving the total dissolution rate and stability of effective ingredients, and ensuring the efficacy of the decoction after preparation by promoting diuresis, benefiting the spleen and improving metabolism.

[0027] Furthermore, the cover structure includes a cover plate 21, which is located on the upper side of the feeding pipe 2. The outer surface of the feeding pipe 2 located on the upper side of the end cap of the extraction tank 1 is fixedly connected to a first hinge seat 22. An L-shaped rotating plate 23 is hinged to the first hinge seat 22. One side of the horizontal plate of the L-shaped rotating plate 23 is fixedly connected to the outer surface of the cover plate 21. Therefore, the cover plate 21 rotates with the first hinge seat 22 as the rotation point. A plurality of U-shaped locking plates 24 arranged in a circumferential array are fixedly connected to the outer surface of the cover plate 21. A second hinge seat 25 is fixedly connected to the outer surface of the feeding pipe 2 near the U-shaped locking plate 24. A pressing rod 26 is hinged to the second hinge seat 25. The end of the pressing rod 26 away from the second hinge seat 25 can be inserted into the notch of the U-shaped locking plate 24. Threaded teeth are provided on the outer surface of the end of the pressing rod 26 away from the second hinge seat 25. A locking sleeve 27 is threaded on the threaded teeth of the pressing rod 26.

[0028] When in use, when the cover plate 21 is closed on the feeding pipe 2, rotate the clamping rod 26 upward so that the clamping rod 26 moves away from the second hinge seat 25 and inserts into the notch of the U-shaped locking plate 24. Twist the locking sleeve 27, and the locking sleeve 27 moves downward under the transmission of the thread teeth and presses against the upper surface of the U-shaped locking plate 24, thereby fixing the cover plate 21 on the feeding pipe 2 and completing the sealing of the feeding pipe 2.

[0029] Furthermore, the stirring mechanism includes a stirring shaft 8, which is located inside the extraction tank 1. Two stirring plates 81 are provided on opposite sides of the lower end of the stirring shaft 8. The two stirring plates 81 are arranged in a cross-shaped inclined manner. The lower side of the stirring plates 81 extends out of the lower side of the stirring shaft 8 and slides in contact with the bottom wall of the extraction tank 1. A drive shaft 82 is provided at the upper end of the stirring shaft 8. The upper end of the drive shaft 82 rotates through the upper surface of the extraction tank 1 in a sealed manner. A drive mechanism 7 for controlling the rotation of the drive shaft 82 is provided on the upper surface of the extraction tank 1.

[0030] During use, the drive mechanism 7 drives the drive shaft 82 to rotate, and the stirring shaft 8 rotates synchronously with the drive shaft 82, so that the stirring plate 81 stirs the medicinal materials at the bottom of the extraction tank 1, thereby improving the extraction efficiency of the medicinal materials.

[0031] Furthermore, a control ring 83 is fixedly connected to the top wall of the extraction tank 1. The upper ends of the drive shaft 82 and the stirring shaft 8 are located at the center of the control ring 83. An annular groove 84 is formed on the inner ring of the control ring 83. The unfolded shape of the annular groove 84 is M-shaped (see attached diagram). Figure 6 The stirring shaft 8 is located on opposite sides of the control ring 83, and a rotating shaft 85 is rotatably connected to each other. The rotating shaft 85 is cylindrical in shape, and the side of the rotating shaft 85 away from the stirring shaft 8 extends into the annular groove 84 and slides in the annular groove 84.

[0032] When the stirring shaft 8 rotates, the rotating shaft 85 moves synchronously with the stirring shaft 8, thereby sliding within the annular groove 84. Since the annular groove 84 has an M-shaped unfolded shape, when the rotating shaft 85 slides from the lower part of the annular groove 84 to the higher part, the rotating shaft 85 drives the stirring shaft 8 to move upward. When the rotating shaft 85 slides from the higher part of the annular groove 84 to the lower part, the stirring shaft 8 moves downward synchronously. Through the above structure, the stirring plate 81 can be moved up and down, thus increasing the stirring range of the stirring plate 81.

[0033] Furthermore, a sliding column 87 is fixedly connected to the upper surface of the stirring shaft 8, and a vertical groove 88 is provided on the lower surface of the drive shaft 82. The upper end of the sliding column 87 extends into the vertical groove 88 and slides within the vertical groove 88. Restricting sliders 89 are fixedly connected to the opposite sides of the upper end of the sliding column 87. A restricting groove 810 is provided on the inner wall of the vertical groove 88 near the restricting slider 89. The other side of the restricting slider 89 extends into the restricting groove 810 and slides within the restricting groove 810. Therefore, when the stirring shaft 8 moves up or down, the sliding column 87 moves up and down synchronously within the vertical groove 88, while the restricting slider 89 slides within the restricting groove 810. Thus, when the drive shaft 82 rotates, the stirring shaft 8 rotates synchronously with the drive shaft 82 under the restriction of the restricting slider 89.

[0034] Furthermore, two transmission cavities 811 are opened inside the lower end of the stirring shaft 8. The two transmission cavities 811 are located on one side near the two stirring plates 81. A swing shaft 812 is fixedly connected to the surface of the stirring plate 81 near the stirring shaft 8. The other end of the swing shaft 812 is sealed and rotatably inserted into the transmission cavity 811. A worm gear 813 is fixedly sleeved on the outer surface of the end of the swing shaft 812 located in the transmission cavity 811. A worm 814 is meshed with the outer surface of the worm gear 813. The lower end of the worm 814 is rotatably connected to the bottom wall of the transmission cavity 811. In use, by controlling the rotation of the worm 814, the worm 814 synchronously meshes and drives the worm gear 813 to rotate. Therefore, the swing shaft 812 can drive the stirring plate 81 to rotate, thereby changing the tilt angle of the stirring plate 81.

[0035] Furthermore, a fixed push rod 815 is provided on the upper side of the worm gear 814. The upper end of the fixed push rod 815 slides through the upper surface of the stirring shaft 8 and is fixedly connected to the lower surface of the drive shaft 82. A first sleeve plate 816 is fixedly sleeved on the outer surface of the lower end of the fixed push rod 815. A first spring 817 is fixedly connected between the upper surface of the first sleeve plate 816 and the top wall of the transmission cavity 811 and is movably sleeved on the outer surface of the fixed push rod 815. A twist rod 818 is fixedly connected to the lower end of the fixed push rod 815. A twist groove 819 is spirally sleeved on the outer surface of the twist rod 818 on the upper surface of the worm gear 814.

[0036] In use, when the stirring shaft 8 is on the side away from the drive shaft 82 and the rotating shaft 85 is at the lower part of the annular groove 84, the first sleeve plate 816 is on the side away from the top wall of the transmission cavity 811, and the first spring 817 is in a free state. The lower end of the twisted rod 818 is on the upper side of the twisted groove 819, and the stirring plate 81 is in an inclined state. When the stirring shaft 8 rotates counterclockwise, the lower side of the inclined stirring plate 81 scrapes along the bottom wall of the extraction tank 1. When the rotating shaft 85 slides from a lower position to a higher position, the stirring shaft 8 gradually moves upward, and the twisted rod 818 moves downward in the twisted groove 819. At the same time, the first spring 817 is stretched, and the worm gear 814 rotates under the drive of the spiral pattern of the twisted rod 818, thereby causing the stirring plate 81 to rotate from an inclined state. When the stirring shaft 8 moves horizontally, as the stirring shaft 8 moves downward, the twisted rod 818 moves upward within the twisted groove 819, causing the stirring plate 81 to gradually rotate from a horizontal position to an inclined position. Through the above structure, the medicinal materials at the bottom of the extraction tank 1 can be lifted up during the upward movement of the stirring shaft 8. The upward lifting action forces the medicinal materials at the bottom to the middle and upper liquid phase and even the gas phase space. When the stirring shaft 8 descends, the medicinal materials on the stirring plate 81 can be sprinkled back down. This achieves a three-dimensional circulation throughout the entire tank, ensuring that each part of the medicinal materials can periodically undergo the complete path from the high-temperature and high-pressure tank bottom to the relatively low-temperature liquid surface area. At the same time, it also better mixes the new and old medicinal materials evenly, greatly increasing the contact probability between the new and old medicinal materials and the solvent, making the extraction more thorough and uniform.

[0037] In this embodiment, the distance between the lowest and highest points of the annular chute 84 is higher than the distance between the bottom wall of the extraction tank 1 and the liquid surface. As the stirring plate 81 moves upward with the stirring shaft 8, it can carry the medicinal materials on the stirring plate 81 out of the liquid surface. In this way, the medicinal materials come into direct contact with the steam in the tank and can undergo brief gas phase heating. When the medicinal materials are re-immersed in the hot liquid, they undergo liquid phase heating again. This "gas-liquid alternation" heating mode can more gently and effectively cause the medicinal material tissue to expand and the cell wall to rupture. It is especially beneficial to the stable dissolution of heat-sensitive components (such as puerarin and some tanshinone) while avoiding local overheating damage caused by continuous high temperature at the bottom.

[0038] Furthermore, a receiving groove 821 is provided on the side surface of the stirring plate 81 facing the rotation direction of the stirring shaft 8. A shaking plate 820 is provided in the receiving groove 821. The outer surface of the shaking plate 820 is in contact with the inner wall of the receiving groove 821 and slides in the receiving groove 821. An inner cavity 823 is provided in the stirring plate 81. A connecting rod 822 is fixedly connected to the surface of the shaking plate 820 facing the inner cavity 823. The other end of the connecting rod 822 slides through the inner cavity 823 in a sealed manner. A second sleeve plate 824 is fixedly connected to one end of the connecting rod 822 located in the inner cavity 823. A second spring 825 is fixedly connected between the second sleeve plate 824 and the inner wall of the inner cavity 823 and is movably sleeved on the outer surface of the connecting rod 822. When the second spring 825 is in a free state, the second spring 825 exerts a thrust on the second sleeve plate 824, so that the initial position of the shaking plate 820 is retracted into the receiving groove 821.

[0039] Furthermore, a trigger rod 826 is provided inside the inner cavity 823. The other end of the trigger rod 826 slides through the stirring plate 81 and the swing shaft 812, and extends into the transmission cavity 811. One end of the trigger rod 826 located in the inner cavity 823 is hinged to the second sleeve plate 824 by a hinged rotating plate 827. One end of the trigger rod 826 located in the transmission cavity 811 is hinged to a one-way rod 828. A torsion spring (not shown in the figure) is hinged between the one-way rod 828 and the trigger rod 826. The one-way rod 828 is under the action of the torsion spring. The trigger rod 826 is kept horizontal. A baffle 829 is fixedly connected to the lower surface of the trigger rod 826 near the one-way rod 828. The other side of the baffle 829 contacts the lower surface of the one-way rod 828, thereby restricting the one-way rod 828 from rotating downward. Multiple trigger protrusions 86 arranged in an arc array are fixedly connected to the inner wall of the transmission cavity 811 near the one-way rod 828. The trigger protrusions 86 are in the shape of isosceles triangles. The other end of the one-way rod 828 away from the trigger rod 826 can slide in contact with the inclined surface of the trigger protrusions 86.

[0040] When the stirring plate 81 rotates from an inclined position to a horizontal position, the trigger rod 826 slides downward synchronously with the swing shaft 812. Since the baffle 829 only blocks the lower side of the one-way rod 828, when the trigger rod 826 contacts the trigger protrusion 86, the one-way rod 828 cannot push the trigger rod 826 to move, and the one-way rod 828 rotates. At the same time, the torsion spring deforms. When the stirring plate 81 rotates from a horizontal position to an inclined position, the trigger rod 826 contacts the trigger protrusion 86 again. Since the baffle 829 restricts the one-way rod 828 from rotating to one side of the baffle 829, the one-way rod 828 can push the trigger rod 826 into the inner cavity 8. The displacement of one side of the 23 hinge plate 827 creates a thrust on the connecting rod 822, causing one side of the shaking plate 820 to move out of the receiving groove 821. Due to the setting of multiple triggering protrusions 86, the shaking plate 820 is repeatedly displaced, which can quickly shake off the medicinal materials on the stirring plate 81 and make them evenly dispersed in the medicinal liquid. At the same time, the high-concentration extract film adhering to the surface of the medicinal materials is "torn off" under the action of the dynamic force. Fresh, low-concentration solvent quickly wets the surface of the medicinal materials when they fall back, which significantly enhances the diffusion driving force of concentration difference and accelerates the migration rate of effective ingredients from the inside of the medicinal materials to the solvent.

[0041] Working principle: The drive mechanism 7 drives the drive shaft 82 to rotate, and the stirring shaft 8 rotates synchronously with the drive shaft 82. The rotating shaft 85 moves synchronously with the stirring shaft 8, thus sliding in the annular groove 84. Since the annular groove 84 unfolds into an M-shape, when the rotating shaft 85 slides from the lower part to the higher part of the annular groove 84, the rotating shaft 85 drives the stirring shaft 8 to move upward. The twisted rod 818 moves downward in the twisted groove 819. At the same time, the first spring 817 is stretched by force, and the worm gear 814 rotates under the drive of the spiral pattern of the twisted rod 818, thereby causing the stirring plate 81 to rotate from an inclined position to a horizontal position. When the rotating shaft 85 slides from the high point to the low point of the annular groove 84, the stirring shaft 8 moves downward synchronously, and the twist rod 818 moves upward in the twist groove 819. As a result, the stirring plate 81 gradually rotates from a horizontal position to an inclined position. The trigger rod 826 contacts the trigger protrusion 86 again. Since the baffle 829 restricts the one-way rod 828 from rotating to one side of the baffle 829, the one-way rod 828 can push the trigger rod 826 to one side of the inner cavity 823. The hinged rotating plate 827 exerts a thrust on the connecting rod 822, causing one side of the shaking plate 820 to move out of the receiving groove 821. Since multiple trigger protrusions 86 are provided, the shaking plate 820 moves repeatedly, shaking the medicinal materials on the stirring plate 81.

[0042] The present invention provides a new technical solution based on the above scheme: a decoction formula for improving spleen metabolism and promoting diuresis, which is made from the following raw materials in parts by weight: 12-18 parts of Alisma plantago-aquatica, 5-10 parts of Atractylodes macrocephala, 12-18 parts of Poria cocos, 8-12 parts of Salvia miltiorrhiza, 8-12 parts of Pueraria lobata, and 10-15 parts of raw hawthorn.

[0043] Alisma plantago-aquatica: sweet and bland in taste, cold in nature, mainly enters the kidney and bladder meridians, and has the effects of promoting water passage and draining dampness, so it is the chief herb in this formula; Atractylodes macrocephala: It tastes sweet and bitter, and is warm in nature. It enters the spleen and stomach meridians. It can strengthen the spleen and replenish qi, dry dampness and promote diuresis. It can enhance the digestive function of the spleen and stomach, reduce the generation of dampness from the root, and at the same time, its ability to dry dampness can assist Alisma plantago-aquatica in removing dampness. It is the assistant herb in this formula. Poria: It is sweet and bland in taste and neutral in nature. It enters the heart, spleen and kidney meridians. It can promote diuresis and eliminate dampness, as well as strengthen the spleen and calm the mind. It can assist Alisma plantago-aquatica in enhancing the diuretic effect and also tonify the spleen. It can prevent Alisma plantago-aquatica from excessively depleting the body's vital energy, thus achieving "dampness elimination without harming the body's vital energy". Therefore, it is the assistant herb in this formula. Danshen: It tastes bitter and is slightly cold in nature. It enters the heart and liver meridians and can clear stagnant blood vessels and resolve "stasis" syndrome caused by dampness. It can promote blood circulation, remove blood stasis, and relieve pain. It is an adjuvant medicine in this prescription. Kudzu root: It has a sweet and pungent taste and a cool nature. It enters the spleen and stomach meridians and can raise the clear yang of the spleen and stomach, generate fluids and quench thirst. Raising yang can help the spleen to transport and transform, and indirectly assist in removing dampness. It is an adjuvant medicine in this formula. Raw hawthorn: It has a sour and sweet taste and is warm in nature. It enters the spleen, stomach and liver meridians. It can help digest food, promote blood circulation and remove blood stasis. It is especially good at resolving greasy meat food stagnation and phlegm. Its turbidity-resolving effect can help clear the "turbid stagnation" (such as phlegm and dampness, food stagnation) derived from dampness. At the same time, hawthorn enters the spleen meridian, which can guide the action of the whole prescription to the spleen and stomach, which is in line with the core function of "strengthening the spleen and removing dampness". It plays the role of "guiding the meridian and acting as the messenger", so it is the guiding medicine.

[0044] This invention conducts experiments based on the above-mentioned formula (hereinafter referred to as the Dampness-Clearing and Spleen-Strengthening Formula), and the experimental steps include: First, a MAFLD mouse (C57BL / 6J) model group was established by feeding the mice with a high-fat diet (HFD) (60% fat, catalog number: HF60, Ditz) for 12 weeks.

[0045] Establish the Shenshi and Pifang intervention group: After 8 weeks of HFD feeding, the Shenshi and Pifang were administered by gavage starting in the 9th week (the dosage was converted according to the human and mouse dosage) for 4 weeks.

[0046] Mice that had been fed normally for 12 weeks were selected as the normal group.

[0047] After week 12, the mice in the three groups were sacrificed, and samples were collected for testing. The results are as follows: like Figure 11 As shown in the figure, A: Body weight curve. B: Final body weight. C: Liver weight. D: Liver-to-body weight ratio. E: Serum AST level. F: Serum ALT level. G: Liver H&E staining. * P <0.05,** P <0.01, *** P <0.001, **** P <0.0001.

[0048] pass Figure 11 It can be seen that, compared with the normal group, the mice in the model group had a significantly increased body size, and the dampness-reducing and spleen-strengthening formulas could effectively reduce HFD-induced weight gain. Figure 11 Compared with the normal group, the model group mice had increased liver weight and a higher liver-to-body weight ratio; however, these results were significantly reduced after the intervention of the dampness-removing and spleen-strengthening formulas. Figure 11 (CD), long-term high-fat diet leads to liver damage, the main marker of which is elevated serum ALT and AST levels. Compared with the model group, serum ALT and AST levels were significantly reduced after the intervention of Shenshi and Pifang. Figure 11 Histopathological examination of liver sections using H&E staining showed that hepatocytes in the model group mice exhibited significant ballooning degeneration and inflammatory cell infiltration, and these pathological features were significantly improved after intervention with Shenshi and Pifang. Figure 11 Therefore, based on the above information, it can be concluded that this formula can reduce body weight and liver damage in MAFLD mice.

[0049] Lipid dysregulation is a major characteristic of MAFLD, and this invention targets the detection of lipid dysregulation, such as... Figure 12 As shown in the figure, A: Liver triglyceride content. B: Liver total cholesterol content. C: Serum triglyceride content. D: Serum total cholesterol content. E: Serum HDL-c content. F: Serum LDL-c content. G: Liver Oil Red O staining. * P <0.05,** P <0.01, *** P <0.001, **** P <0.0001.

[0050] Through append Figure 12 It was found that compared with the normal group, the lipid water content in the liver and serum of mice in the model group was significantly increased, especially total triglycerides and total cholesterol. However, these indicators were reversed after the intervention of dampness-removing and spleen-strengthening formula. Figure 12 In addition, compared with the model group, serum LDC-c levels were significantly reduced and HDL-c levels were significantly increased after the intervention of Shenshi and Pifang. Figure 12 Oil Red O staining results showed that, compared with the model group, the intervention of Shenshi and Pifang significantly reduced the size and number of lipid droplets in the liver. Figure 12 G).

[0051] Given that insulin resistance is a significant factor in the development of MAFLD, this invention evaluated glucose and insulin tolerance in mice in different groups, such as... Figure 13 As shown in the figure, AD represents the glucose tolerance test and mouse insulin resistance test, along with the AUC curve. *P <0.05,** P <0.01, *** P <0.001, **** P <0.0001.

[0052] pass Figure 13 It can be seen that, compared with the model group, the glucose tolerance and insulin sensitivity of mice were significantly improved after the intervention of the dampness-removing and spleen-strengthening formula.

[0053] According to the above-mentioned scheme, the present invention also provides a preparation process for preparing a decoction that promotes diuresis, benefits the spleen, and improves metabolism using a preparation machine. The operation steps are as follows: S1. Rinse and drain Alisma plantago-aquatica and Poria cocos; wash Atractylodes macrocephala, Salvia miltiorrhiza and Pueraria lobata and soak them in 30℃ drinking water for 30 minutes; wash raw hawthorn and then use a high-speed blender to lightly break down the cell walls, which greatly increases the contact area between the pulp and the solvent and promotes the rapid dissolution of organic acids and other components. S2. Load Atractylodes macrocephala and hawthorn into the first feeding chamber of the equipment, and load Alisma plantago-aquatica, Poria cocos, Salvia miltiorrhiza and Pueraria lobata into the second feeding chamber. Close feeding pipe 2 and set the extraction program through the controller, that is, open the second feeding chamber in the first decoction stage and open the first feeding chamber in the second decoction stage. S3. The water supply equipment adds drinking water (approximately 9 times the volume) to the extraction tank 1 through the water supply pipe 3. The program starts: the first feeding chamber is closed, only the second feeding chamber is opened, the stirrer is started, and the stirring is carried out at a low speed of 20 r / min. The heating resistance wire 9 is started to heat the tank according to the preset program, that is, the temperature rises from 25℃ to 68℃ within 15 minutes, is maintained for 8 minutes, and then rises to 102℃ within 8 minutes (gradual heating). When the temperature reaches 100-105℃, the pressurized gas source maintains the pressure inside the extraction tank 1 at 0.08-0.12MPa (i.e., slightly positive pressure) through the pressurized pipe 4. Under these conditions, the tank is decocted for 40 minutes. After the time is up, the pressure is reduced, and the first decoction is collected through the liquid outlet pipe 10 and filtered through a three-stage filter to obtain the first decoction filtrate. A slightly positive pressure environment can slightly increase the boiling point and enhance the cell wall breaking ability of medicinal plants, which is especially beneficial to the dissolution of components such as Alisma plantago-aquatica triterpenes and Poria cocos polysaccharides. At the same time, it shortens the extraction time. The programmed temperature control curve (such as first soaking at medium temperature and then raising to the boiling point) helps the heat-sensitive components in Salvia miltiorrhiza and Pueraria lobata to be released slowly and reduce heat loss. S4. Add hot water (about 5 times the amount) to the dregs in the tank through water supply pipe 3. Open the first feeding chamber of the controller to let the Chinese medicinal materials fall into the tank. Simmer over low heat for 30 minutes at normal pressure and 90-95℃. After the end, collect the second decoction, filter it, and obtain the second decoction filtrate. This stage mainly extracts the remaining effective components. Mild conditions can prevent the decomposition or adverse changes of certain components (such as organic acids in hawthorn) under long-term decoction. S5. Combine the first and second decoction filtrates to obtain a decoction that promotes diuresis, benefits the spleen, and improves metabolism.
