Description

Technical Field

[0001] This invention relates to the field of intestinal regulation drug preparation, specifically to a probiotic fermentation device and fermentation method for regulating intestinal function. Background Technology

[0002] In human health management, gut function regulation is considered a crucial foundation for maintaining immune homeostasis, promoting nutrient absorption, and improving metabolic balance. Studies have shown that improving gut microbiota structure through probiotic intake is one of the safest and most effective long-term regulatory methods. However, different probiotics exhibit variations in bioactivity, tolerability, and the utilization of functional components such as polyphenols. Therefore, an increasing number of solutions in the industry tend to combine probiotics with plant-based bioactive substances or pre-ferment some raw materials with probiotics to enhance their bioavailability and physiological effects. Partial fermentation of components such as tea polyphenols and dietary fiber by specific strains—such as *Lactobacillus plantarum*—can significantly reduce bitterness, improve stability, and generate more small-molecule metabolites with prebiotic effects, thereby enhancing the overall gut health regulation effect.

[0003] In existing probiotic fermentation equipment, foam control remains a critical issue affecting the stability of the fermentation process. Traditional fermenters commonly employ single-sided stirring blades, top spraying, or chemical defoamers to suppress foam. However, unidirectional stirring structures have limited coverage of the liquid surface area, and their defoaming effect is often concentrated in localized areas, making it difficult to comprehensively intervene in the continuously rising and spreading foam. Especially in systems fermented with highly active strains or containing polysaccharide or polyphenol matrix, foam has strong adhesion and is more likely to accumulate in areas that are difficult for the stirring blades to reach.

[0004] Traditional equipment lacks structural designs for "double-sided compression" or "clamping-type foam rupture," resulting in foam rupture primarily relying on single-point cutting or localized disturbance, thus limiting both foam rupture efficiency and rupture path. When the foam accumulation rate exceeds its elimination rate, it not only reduces the effective volume of the tank but also affects dissolved oxygen supply and the stability of the fermentation environment.

[0005] Based on this, this application proposes a "clamping" synergistic defoaming structure formed by a first defoaming section and a second defoaming section arranged in an interleaved manner. The two cooperate with each other during the fermentation process and implement a continuous, active and deep defoaming mechanism through bidirectional extrusion, differential shearing and alternating bursting, thereby significantly improving the problems of insufficient defoaming coverage and low foam breaking efficiency in the prior art. Summary of the Invention

[0006] In order to solve the problem of defoaming in existing fermentation equipment, this invention provides a probiotic fermentation device and fermentation method that regulates intestinal function.

[0007] The present invention solves the above-mentioned technical problems through the following technical solutions: This invention provides a probiotic fermentation device for regulating intestinal function, including a tank body. The top and bottom of the tank body are respectively provided with an inlet and an outlet. A sealing cover is provided on the inlet and a valve is provided on the outlet. A drive assembly is provided at the center of the top of the tank body. The output end of the drive assembly is fixedly connected to the top of the drive shaft. The drive shaft penetrates the top side wall of the tank body vertically and extends to the bottom of the inner cavity of the tank body. A stirring blade is fixed on the side surface of the drive shaft near the bottom of the inner cavity of the tank body. The upper part of the drive shaft is provided with a defoaming component with differential defoaming function. The defoaming component includes a first defoaming part that rotates synchronously with the drive shaft and multiple second defoaming parts that are driven to run differentially by the drive shaft. The first defoaming part and the second defoaming part are arranged alternately.

[0008] The first and second defoaming parts, which are arranged in an alternating manner, defoam the inside of the tank. The first defoaming part, which rotates synchronously with the drive shaft, continuously stirs the liquid near the liquid surface inside the tank to perform active defoaming. The second defoaming part, driven by the drive shaft, forms a speed difference with the continuously rotating first defoaming part, creating a sandwich effect on the bubbles, thereby achieving better defoaming.

[0009] In this technical solution, the first defoaming part and the second defoaming component mesh with each other, and the second defoaming part is driven by the rotating drive shaft to achieve differential active defoaming; The first defoaming section includes at least one rotating defoaming unit connected to the drive shaft, and the second defoaming section includes a support unit. The support unit is fixed in position inside the tank, and multiple differential defoaming units are provided on the support unit that can slide and reset after sliding. The defoaming ends on the differential defoaming units and the defoaming ends on the rotating defoaming units are interlocked and meshed with each other. The drive shaft drives the differential defoaming unit to slide and then reset through the transmission components, forming a swinging motion.

[0010] The first defoaming unit rotates synchronously with the drive shaft, while the drive shaft drives the differential defoaming unit to slide and then reset through the transmission assembly, thereby achieving a different speed, amplitude, and trajectory than the first defoaming unit, thus realizing differential defoaming.

[0011] In this technical solution, the differential defoaming unit is slidably connected to the bearing unit through a spring-loaded sliding unit, and the trajectory of the differential defoaming unit being pushed and slid by the transmission component is an arc shape, and the arc shape is concentric with the drive shaft.

[0012] That is, the differential defoaming unit oscillates in an arc-shaped trajectory.

[0013] In this technical solution, the bearing unit includes a bearing ring, which is sleeved around the drive shaft and is concentrically arranged with the drive shaft. The bearing ring is fixed in position inside the tank, and the differential defoaming units are distributed in a ring array on the bearing ring. The bearing ring has sliding slots that are the same number as the differential defoaming units. The sliding units pass through the bearing ring through the sliding slots. The side of the sliding unit near the drive shaft is connected to the driven plate. The driven plate is connected to the drive assembly in the inner ring of the bearing ring. The other side of the sliding unit is connected to the differential defoaming unit.

[0014] In this technical solution, the sliding unit includes a connecting rod that passes through the bearing ring via a sliding groove. The connecting rod is arranged radially along the bearing ring and is slidably connected to the bearing ring via a retractable and resilient inner guide and an outer sliding member.

[0015] In this technical solution, the inner guide and the outer sliding member are respectively disposed on the inner ring sidewall and the outer ring sidewall of the bearing ring; The inner guide component includes two symmetrically arranged guide arc rods, which are telescopic. The two guide arc rods are fixed on the two end faces of the connecting rod, and the ends of the two guide arc rods are fixed on the inner ring side wall of the bearing ring. The two guide arc rods are concentric with the bearing ring. Springs are sleeved on the surface of the guide arc rods, and the two ends of the springs are fixed to the two ends of the guide arc rods.

[0016] In this technical solution, the sliding component includes a slider, which is fixed to the end of the connecting rod and slidably connected to the arc-shaped guide rail. The guide rail is fixed to the outer wall of the bearing ring on one side of the sliding groove.

[0017] When the driven plate is pushed, the slider connected to the driven plate slides on the guide rail, which causes one of the guide arc rods to be stretched and the other guide arc rod to be compressed. The spring on the guide arc rod deforms and accumulates elastic potential energy to push the slider back to its original position.

[0018] In this technical solution, the differential defoaming unit is fixedly connected to the sliding part through a synchronizing rod. The differential defoaming unit includes a second mounting vertical rod, on which a plurality of equally spaced second mounting horizontal rods are fixed. On the second mounting horizontal rod, a plurality of equally spaced second misaligned rods are fixed. The second misaligned rods are arranged vertically, and two symmetrically arranged second defoaming rods are fixed at the ends of the second misaligned rods. The second mounting crossbar is distributed radially along the bearing ring.

[0019] A guide sleeve is provided above the bearing ring. The vertical projection of the guide sleeve completely covers the bearing ring, preventing the material from directly stopping on the bearing ring and other structures supported by the bearing ring when it is put into the tank from the inlet.

[0020] In this technical solution, the rotating defoaming unit is fixedly connected to the drive shaft via a carrier plate. The carrier plate is sleeved and fixed on the surface of the drive shaft. The rotating defoaming unit includes a first mounting vertical rod, which is fixed on the carrier plate or on the tip of an auxiliary blade. Multiple first mounting horizontal rods with equal spacing and radially distributed along the drive shaft are fixed on the surface of the first mounting vertical rod. Multiple equally spaced first misaligned rods are fixed on the first mounting crossbar, and two symmetrically arranged first defoaming rods are fixed to the ends of the first misaligned rods.

[0021] The end of the first defoaming rod is the defoaming end on the rotating defoaming unit.

[0022] In this technical solution, the number of first mounting crossbars on a single rotating defoaming unit and the number of second mounting crossbars on a single differential defoaming unit are the same, and they are staggered vertically to avoid interference during rotation. The first misaligned rod and the second misaligned rod are staggered with each other, that is, one of the first misaligned rod and the second misaligned rod extends upward and the other extends downward, so that the first defoaming rod and the second defoaming rod on the corresponding first misaligned rod and the second misaligned rod are on the same horizontal plane.

[0023] The two symmetrical first defoaming rods and the first mounting crossbar form a cross shape, and the two symmetrical second defoaming rods and the second mounting crossbar also form a cross shape.

[0024] Both the first and second defoaming rods have an arc-shaped structure.

[0025] The defoaming effect is enhanced by using a first and second defoaming rod that are on the same horizontal plane and mesh with each other.

[0026] In this technical solution, the transmission component includes a bearing block, a mounting bracket is fixed on one end face of the bearing block near the drive shaft, a self-rotating sleeve is sleeved on the mounting bracket, and a transmission plate that can overlap with the sliding unit is fixed on the surface of the self-rotating sleeve, that is, overlap with the transmission plate on the sliding unit. The self-rotating sleeve is arranged vertically. A coil spring is fitted onto the surface of the rotating sleeve, with its two ends acting on the rotating sleeve and the mounting bracket, respectively. The load-bearing block is fixed to the drive shaft or the extension end of the drive shaft by a fixing rod.

[0027] When the bearing block rotates synchronously with the drive shaft via the fixed rod, the transmission plate, which rotates synchronously with the bearing plate, comes into contact with the driven plate. Under the action of the spring force, the transmission plate does not rotate, thus pushing the driven plate to move until it reaches the end of the slide groove. At this point, the driven plate stops moving, while the transmission plate rotates. The rotating transmission plate then disengages from the driven plate.

[0028] A fermentation method for producing raw materials for probiotics that regulate intestinal function includes the following steps: (1) Preparation of tea polyphenol solution; (2) Pre-treat the tea polyphenol solution by pouring the tea polyphenol solution into the tank and then heating it to 40℃~50℃ and maintaining it for 10~20 minutes or introducing inert gas to reduce dissolved oxygen in the solution. (3) Inoculate the pretreated tea polyphenol solution with Lactobacillus plantarum solution, i.e., put Lactobacillus plantarum solution into the tank; (4) Pre-fermentation is carried out under controlled conditions, with a fermentation temperature of 30℃~37℃ and an initial pH of 5.8~6.2. Fermentation is carried out for 4~12 hours in a micro-aerobic or anaerobic environment, so that the pH of the fermentation system naturally decreases to 4.0~4.5; (5) Cool or lightly sterilize to terminate fermentation and obtain tea polyphenol fermentation broth partially pre-fermented by Lactobacillus plantarum. Then freeze-dry the fermentation broth to obtain pre-fermented tea polyphenol freeze-dried powder.

[0029] Preferably, the stirring speed during fermentation is controlled at 100-200 rpm to reduce the oxidation rate of tea polyphenols, while defoaming is achieved through a defoaming component.

[0030] Furthermore, the obtained fermented tea polyphenol freeze-dried powder is mixed with compound probiotic powder, resistant dextrin, inulin, vitamin B1, vitamin B2, vitamin D and erythritol / xylitol to form a probiotic mixture that regulates intestinal function; The mixture comprises: 2%–15% compound probiotic powder, 5%–20% freeze-dried fermented tea polyphenol powder, 10%–60% resistant dextrin, 10%–50% inulin, 0.075%–0.3% vitamin B1, 0.075%–0.3% vitamin B2, 0.0000625%–0.000625% vitamin D, and 0%–40% erythritol / xylitol.

[0031] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0032] The positive and progressive effects of this invention are as follows: By incorporating interlocking first and second defoaming sections inside the tank, a synergistic dynamic defoaming mechanism is created during fermentation. The first defoaming section rotates synchronously with the drive shaft, continuously agitating and cutting the foam near the liquid surface to actively eliminate newly generated foam. Meanwhile, the second defoaming section moves at different speeds, amplitudes, and trajectories under the drive shaft, creating a significant speed difference relative to the first defoaming section.

[0033] With this differential speed structure, the foam inside the tank is subjected to a bidirectional squeezing and shearing action, similar to a "pincer attack," between the two defoaming sections. This not only increases the frequency of foam bursting but also accelerates the release efficiency of gas inside the bubbles. Compared to defoaming methods that rely solely on a single rotating component, this staggered arrangement can cover a wider liquid surface area, creating a more thorough disturbance path and avoiding local dead zones. This significantly improves the overall defoaming speed and effectiveness, ensuring stable operation of the fermentation process even in high-foaming environments. Attached Figure Description

[0036] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments.

[0037] like Figures 1-3 As shown, a probiotic fermentation device for regulating intestinal function includes a tank 1. The top and bottom of the tank 1 are respectively provided with an inlet 13 and an outlet 12. A sealing cover is provided on the inlet 13 and a valve is provided on the outlet 12. A drive assembly is provided at the center of the top of the tank 1. The output end of the drive assembly is fixedly connected to the top of the drive shaft 4. The drive shaft 4 penetrates the top side wall of the tank 1 vertically and extends to the bottom of the inner cavity of the tank 1. A stirring blade 41 is fixed on the side surface of the drive shaft 4 near the bottom of the inner cavity of the tank 1. The upper part of the drive shaft 4 is provided with a defoaming component with differential defoaming function. The defoaming component includes a first defoaming part 7 that rotates synchronously with the drive shaft 4 and multiple second defoaming parts 8 that are driven by the drive shaft 4 to run differentially. The first defoaming part 7 and the second defoaming part 8 are arranged alternately.

[0038] The drive assembly includes a motor, which is fixed to a bracket 2. The bracket 2 is fixed to the top side wall of the tank 1. The output end of the motor is fixedly connected to the top of the drive shaft 4 via a connector 3. The motor is not shown in the figure. The connector 3 is a coupling or reducer that is already in the prior art. The motor drives the drive shaft 4 to rotate via the connector 3.

[0039] like Figure 5 As shown, the first defoaming part 7 and the second defoaming component mesh with each other, and the second defoaming part 8 is driven by the rotating drive shaft 4 to achieve differential active defoaming. The first defoaming section 7 includes at least one rotating defoaming unit connected to the drive shaft 4. The second defoaming section 8 includes a support unit. The support unit is fixed in position inside the tank 1. Multiple differential defoaming units 85 are provided on the support unit and can be slidable and reset after sliding. The defoaming ends on the differential defoaming units 85 and the defoaming ends on the rotating defoaming units are interlocked and meshed with each other. The drive shaft 4 drives the differential defoaming unit 85 to slide and then reset through the transmission component 9, forming a swing motion.

[0040] Multiple equally spaced support rods 11 are fixed on the outer wall of the tank body 1.

[0041] The first defoaming unit 7 rotates synchronously with the drive shaft 4, while the drive shaft 4 drives the differential defoaming unit 85 to slide and then reset through the transmission assembly 9, thereby achieving a different speed, amplitude and running trajectory than the first defoaming unit 7, thus realizing differential defoaming.

[0042] The rotating defoaming unit rotates synchronously with the drive shaft 4, meaning it defoams along the direction of liquid rotation in the tank 1. Meanwhile, the differential defoaming unit 85, after rotating a certain distance with the drive shaft 4, returns to its original position, creating a oscillation that causes the liquid in the tank 1 to actively "collide" with the differential defoaming unit 85, thus frequently and locally "pinching" the bubbles. This is particularly suitable for defoaming viscous liquids.

[0043] Specifically, the differential defoaming unit 85 is slidably connected to the bearing unit through a spring-loaded sliding unit, and the trajectory of the differential defoaming unit 85 being pushed and slid by the transmission component 9 is an arc shape, and the arc shape trajectory is concentric with the drive shaft 4.

[0044] That is, the differential defoaming unit 85 oscillates in an arc-shaped trajectory.

[0045] Specifically, such as Figure 6 and Figure 9 As shown, the bearing unit includes a bearing ring 81, which is sleeved around the drive shaft 4 and is concentrically arranged with the drive shaft 4. The bearing ring 81 is fixed inside the tank 1, and the differential defoaming unit 85 is distributed in a ring array on the bearing ring 81. The bearing ring 81 has sliding slots 811 in the same number as the differential defoaming units 85. The sliding units pass through the bearing ring 81 via the sliding slots 811. The side of the sliding unit near the drive shaft is connected to the driven plate 83. The driven plate 83 is connected to the drive assembly in the inner ring of the bearing ring 81. The other side of the sliding unit is connected to the differential defoaming unit 85.

[0046] When the drive shaft 4 drives the drive assembly to rotate, the drive assembly moves to the driven plate 83 and pushes the driven plate 83 to move in an arc-shaped trajectory. This causes the differential defoaming unit 85 to slide on the bearing ring 81 through the sliding unit until the drive assembly disengages from the transmission plate 93. Then the sliding unit rebounds, causing the differential defoaming unit 85 to return to its original position, thus realizing the swing of the differential defoaming unit 85 on an arc-shaped trajectory.

[0047] like Figure 12 As shown, the sliding unit includes a connecting rod 82, which passes through the bearing ring 81 via a sliding groove 811. The connecting rod 82 is arranged radially along the bearing ring 81, and is slidably connected to the bearing ring 81 via a retractable and elastic inner guide and an outer sliding member.

[0048] The inner guide and the outer sliding member are respectively provided on the inner ring sidewall and the outer ring sidewall of the bearing ring 81; The inner guide includes two symmetrically arranged guide arc rods 86, which are telescopic. The two guide arc rods 86 are fixed on the two end faces of the connecting rod 82, and the ends of the two guide arc rods 86 are fixed on the inner ring side wall of the bearing ring 81. The two guide arc rods 86 are concentrically arranged with the bearing ring 81. A spring is sleeved on the surface of the guide arc rod 86, and the two ends of the spring are fixed to the two ends of the guide arc rod 86.

[0049] The sliding component includes a slider 87, which is fixed to the end of the connecting rod 82. The slider 87 is slidably connected to the arc-shaped guide rail 88, which is fixed to the outer wall of the bearing ring 81 on one side of the sliding through groove 811.

[0050] When the driven plate 83 is pushed, the slider 87 connected to the driven plate 83 slides on the guide rail 88, thereby causing one of the guide arc rods 86 to be stretched and the other guide arc rod 86 to be compressed. The spring on the guide arc rod 86 deforms and accumulates elastic potential energy to push the slider 87 back to its original position.

[0051] The extension and retraction of the guide arc rod 86 and the sliding connection between the slider 87 and the guide rail 88 both provide guidance for the movement of the differential defoaming unit 85, improving the stability of the differential defoaming unit 85 during movement. The spring provides driving force for the differential defoaming unit 85 to slide and reset. When the springs on the two guide arc rods 86 do not deform or the two guide arc rods 86 are not subjected to any external force other than the spring force and gravity, the connecting rod 82 is located at the center of the sliding through groove 811.

[0052] like Figures 9-11 as well as Figure 13As shown, the differential defoaming unit 85 is fixedly connected to the sliding part through the synchronizing rod 84. The differential defoaming unit 85 includes a second mounting vertical rod 851, a plurality of equally spaced second mounting horizontal rods 852 are fixed on the second mounting vertical rod 851, a plurality of equally spaced second misaligned rods 853 are fixed on the second mounting horizontal rods 852, the second misaligned rods 853 are arranged vertically, and two symmetrically arranged second defoaming rods 854 are fixed at the ends of the second misaligned rods 853. The second mounting crossbar 852 is distributed radially along the bearing ring 81.

[0053] A guide sleeve 5 is provided above the bearing ring 81. The vertical projection of the guide sleeve 5 completely covers the bearing ring 81, so as to prevent the material from directly staying on the bearing ring 81 and other structures supported by the bearing ring 81 when it is put into the tank 1 through the feed port 13.

[0054] The top of the material guide sleeve 5 is a frustum-shaped structure, and the bottom is a cylindrical structure. The top of the material guide sleeve 5 is fitted onto the surface of the drive shaft 4, and the material guide sleeve 5 is fixed to the inner wall of the tank 1 by rods.

[0055] The end of the second defoaming rod 854 is the defoaming end on the differential defoaming unit 85.

[0056] The bearing ring 81 is connected to the inner wall of the guide sleeve 5 or directly to the inner wall of the tank 1 via the fixing rod 812.

[0057] like Figure 11 As shown, the synchronizing rod 84 has an "L" shaped structure, and the end of the synchronizing rod 84 passes over the entire differential defoaming unit 85 from above or below, and is fixedly connected to the outer wall of the corresponding second mounting vertical rod 851 on the side away from the bearing ring 81.

[0058] In this technical solution, it is preferable to place the bearing ring 81 above the first defoaming part 7.

[0059] like Figure 7 As shown, the rotating defoaming unit is fixedly connected to the drive shaft 4 via the support plate 6. The support plate 6 is sleeved and fixed on the surface of the drive shaft 4. The rotating defoaming unit includes a first mounting vertical rod 71. The first mounting vertical rod 71 is fixed on the support plate 6 or on the top of the auxiliary blade 61 fixed on the support plate 6. Multiple first mounting horizontal rods 72 with equal spacing and radially distributed along the drive shaft 4 are fixed on the surface of the first mounting vertical rod 71. Multiple equally spaced first misaligned rods 73 are fixed on the first mounting crossbar 72, and two symmetrically arranged first defoaming rods 74 are fixed on the ends of the first misaligned rods 73.

[0060] Multiple auxiliary blades 61 are arranged in a ring array on the annular surface of the bearing disk 6.

[0061] The end of the first defoaming rod 74 is the defoaming end on the rotating defoaming unit.

[0062] like Figure 14 As shown, the number of first mounting crossbars 72 on a single rotating defoaming unit and the number of second mounting crossbars 852 on a single differential defoaming unit 85 are the same, and they are staggered vertically to avoid interference during rotation. The first misaligned bar 73 and the second misaligned bar 853 are staggered, that is, one of the first misaligned bar 73 and the second misaligned bar 853 extends upward and the other extends downward, so that the first defoaming bar 74 and the second defoaming bar 854 on the corresponding first misaligned bar 73 and the second misaligned bar 853 are on the same horizontal plane.

[0063] Two symmetrical first defoaming rods 74 and the first mounting crossbar 72 form a cross shape, and two symmetrical second defoaming rods 854 and the second mounting crossbar 852 also form a cross shape.

[0064] Both the first defoaming rod 74 and the second defoaming rod 854 have an arc-shaped structure.

[0065] The defoaming effect is enhanced by the first defoaming rod 74 and the second defoaming rod 854 that are on the same horizontal plane and mesh with each other.

[0066] Preferably, the ends of the first defoaming rod 74 and the second defoaming rod 854 are pointed.

[0067] like Figure 5 and Figure 15 As shown, the transmission assembly 9 includes a support block 92. A mounting bracket 94 is fixed on one end face of the support block 92 near the drive shaft 4. A rotatable self-rotating sleeve 95 is sleeved on the mounting bracket 94. A transmission plate 93 that can overlap with the sliding unit is fixed on the surface of the self-rotating sleeve 95. That is, it overlaps with the transmission plate 93 on the sliding unit. The self-rotating sleeve 95 is arranged vertically. A coil spring is fitted onto the surface of the rotating sleeve 95, and the two ends of the coil spring act on the rotating sleeve 95 and the mounting bracket 94 respectively. The bearing block 92 is fixed to the drive shaft 4 or the extension end of the drive shaft 4 by the fixing rod 91.

[0068] In one scenario, when the bearing block 92 rotates synchronously with the drive shaft 4 via the fixed rod 91, the transmission plate 93, which rotates synchronously with the bearing block 92, comes into contact with the driven plate 83. Under the action of the spring's own elasticity, the transmission plate 93 does not rotate, thus pushing the driven plate 83 to move until it reaches the end of the slide groove. At this point, the driven plate 83 stops moving, while the transmission plate 93 rotates, and the rotating transmission plate 93 disengages from the driven plate 83.

[0069] After disengaging from the driven plate 83, the transmission plate 93 rotates back to its original position during the process of the coil spring recovering its deformation.

[0070] In another scenario, after the transmission plate 93, which rotates synchronously with the bearing block 92, comes into contact with the driven plate 83, it begins to rotate relative to the driven plate 83. However, it still pushes the driven plate 83 to move until the transmission plate 93 rotates to the point of disengaging from the surface of the driven plate 83, or until the transmission plate 93 moves to the end of the slide groove, the transmission plate 93, which continues to rotate, disengages from the surface of the driven plate 83.

[0071] The tank 1 in this application is also provided with other common structures in the prior art, such as heating and insulation structures, oxygenation structures, and other structures used for fermentation.

[0072] A fermentation method for producing raw materials for probiotics that regulate intestinal function includes the following steps: (1) Preparation of tea polyphenol solution; (2) Pre-treat the tea polyphenol solution by pouring the tea polyphenol solution into the tank 1 and then heating it to 40℃~50℃ and maintaining it for 10~20 minutes or introducing inert gas to reduce dissolved oxygen in the solution. (3) Inoculate the pretreated tea polyphenol solution with Lactobacillus plantarum solution, i.e., put Lactobacillus plantarum solution into the tank; (4) Pre-fermentation is carried out under controlled conditions, with a fermentation temperature of 30℃~37℃ and an initial pH of 5.8~6.2. Fermentation is carried out for 4~12 hours in a micro-aerobic or anaerobic environment, so that the pH of the fermentation system naturally decreases to 4.0~4.5; (5) Cool or lightly sterilize to terminate fermentation and obtain tea polyphenol fermentation broth partially pre-fermented by Lactobacillus plantarum. Then freeze-dry the fermentation broth to obtain pre-fermented tea polyphenol freeze-dried powder.

[0073] During fermentation, the stirring speed is controlled at 100-200 rpm to reduce the oxidation rate of tea polyphenols, while defoaming is achieved through the defoaming component.

[0074] The obtained fermented tea polyphenol freeze-dried powder is mixed with compound probiotic powder, resistant dextrin, inulin, vitamin B1, vitamin B2, vitamin D and erythritol / xylitol to form a probiotic mixture that regulates intestinal function; The mixture comprises: 2%–15% compound probiotic powder, 5%–20% freeze-dried fermented tea polyphenol powder, 10%–60% resistant dextrin, 10%–50% inulin, 0.075%–0.3% vitamin B1, 0.075%–0.3% vitamin B2, 0.0000625%–0.000625% vitamin D, and 0%–40% erythritol / xylitol.

[0075] Fermented tea polyphenol freeze-dried powder can also be replaced with green tea extract to reduce the overall cost of the mixture.

[0076] Compared to traditional green tea extracts, fermented tea polyphenol freeze-dried powder contains more easily absorbed small-molecule polyphenols and GABA metabolites, thus increasing anti-inflammatory and antioxidant effects. When preparing the mixture, simply dry-mix all the raw materials.

[0077] Specifically, the compound probiotic powder is a mixture of Bifidobacterium animalis subsp. lactis, Lactobacillus acidophilus, Bifidobacterium longum subsp. longis, Lactobacillus rhamnosus, Bifidobacterium adolescentis, Lactobacillus plantarum, and Bifidobacterium bifidum.

The protection scope of this invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of this invention, but all such changes and modifications shall fall within the protection scope of this invention.
