Description

Technical Field

[0001] This invention specifically relates to a multi-strain synergistic fermentation device for traditional Chinese medicine, belonging to the field of traditional Chinese medicine fermentation technology. Background Technology

[0002] Multi-strain synergistic fermentation technology for traditional Chinese medicine is one of the key directions for promoting the modernization and innovation of traditional Chinese medicine in recent years. This technology introduces a variety of probiotics (such as molds, yeasts, and lactic acid bacteria) to synergistically ferment the substrate of traditional Chinese medicine, which can produce new active metabolites, reduce potential toxicity, enhance bioavailability and improve taste, thereby developing more distinctive new traditional Chinese medicine products.

[0003] However, existing Chinese medicine fermentation equipment and technical solutions have the following problems in practical applications: 1. Traditional processes typically require the separate activation and propagation of multiple microbial strains in independent shake flasks or small fermenters. After completion, the strains are then inoculated into the main fermenter via open or semi-open transfer methods. This process involves multiple manual operations, container transfers, and pipeline connections, which is not only cumbersome and inefficient, but also highly susceptible to introducing contaminants during the transfer process, leading to the failure of the entire batch of fermentation and seriously affecting the consistency and safety of the product.

[0004] 2. Different strains have different optimal growth conditions and inoculation times. Ideal co-fermentation often requires strains to be introduced into the main fermenter in a specific sequence (such as first introducing aerobic bacteria to decompose cellulose, and then introducing anaerobic bacteria for transformation) or precisely and synchronously. Existing equipment lacks an integrated mechanism for independent cultivation and controlled release of strains, making it difficult to achieve this refined process control and limiting the targeted optimization of fermentation product profiles.

[0005] 3. After fermentation, the fermentation mash usually requires solid-liquid separation to obtain supernatant or further processing. Traditional equipment often requires all materials to be discharged to external separation equipment, which is complicated and increases the risk of exposure and contamination. The equipment itself lacks flexible and integrated preliminary solid-liquid separation functions.

[0006] To address the aforementioned issues, there is an urgent need to develop a novel multi-strain synergistic fermentation device for traditional Chinese medicine that is controllable, highly efficient in mixing, and reduces the risk of contamination. This application aims to provide a device that independently cultivates, sequentially and synchronously inoculates, and efficiently mixes strains to meet the pressing needs of modern traditional Chinese medicine fermentation processes for precision, automation, and stability.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-11As shown, a multi-strain synergistic fermentation device for traditional Chinese medicine includes a culture tank 1 and a fermentation tank 2. The culture tank 1 is fixedly installed on the top of the fermentation tank 2. Multiple culture chambers 3 are evenly distributed inside the culture tank 1. A pushing component 4 is installed on the culture tank 1 to move the traditional Chinese medicine substrate within the culture chambers 3. A sliding discharge plate 5 is installed at the bottom of each culture chamber 3. A stirring component 6 is installed inside the fermentation tank 2 to mix and stir the traditional Chinese medicine substrate. A liquid discharge component 7 is installed at the bottom of the fermentation tank 2 to discharge the fermentation liquid. This device vertically sets the independent activation and expansion stages of the microorganisms in space and achieves automatic, aseptic transfer and efficient mixing of materials through a precisely linked mechanical structure. This device solves the problems of traditional traditional Chinese medicine fermentation... To address the issues of cumbersome operation, easy contamination, and difficulty in achieving sequential co-inoculation of multiple microbial strains during the preparation of microbial strains for primary fermentation, a separate culture chamber 3 is established. Different microbial strains (such as molds, yeasts, and lactic acid bacteria) are activated and propagated in solid or liquid states. The culture medium is a pretreated traditional Chinese medicine matrix. It is important to note that a certain amount of pulverized traditional Chinese medicine matrix can be added to the culture chamber 3 through the sealing door 16. This traditional Chinese medicine matrix requires pulverization of the traditional Chinese medicine substrate, homogenization in a premixing chamber, and sterilization at 121℃ for 20 minutes. Furthermore, the culture chamber 3 requires CIP cleaning and UV sterilization. After cultivation, the mature microbial-matrix mixture from each chamber is pushed synchronously or sequentially into the lower fermentation tank 2 via the pushing component 4 through a sealed channel.

[0022] Inside the fermentation tank 2, the stirring component 6 achieves thorough and uniform mixing of various microorganisms and the traditional Chinese medicine base, and carries out synergistic fermentation under a controlled environment. After fermentation, the liquid outlet component 7 achieves precise diversion and collection of the fermentation supernatant, or performs solid-liquid separation. It should be noted that both the fermentation tank 2 and the culture tank 1 of this device need to be connected to external temperature control equipment (such as a jacketed circulating temperature control device, whose circulation pipeline is connected to the jacket layer of the fermentation tank 2 and the culture tank 1, and the heat transfer medium (water, heat transfer oil) is driven by the pump to circulate in the jacket to achieve precise temperature control inside the tank) to achieve microbial fermentation. Since this is not an improvement point of this device, and it is a common existing technology on the market, the structure of this device is not described.

[0023] A sealing door 8 is hinged to the outer circumference of the culture tank 1. The sealing door 8 is located at one end of the culture chamber 3. A storage frame 9 is evenly fixedly installed on the outer circumference of the culture tank 1. One end of the discharge plate 5 is slidably engaged in the storage frame 9. A sealing door 16 is tightly inserted into the top of one end of the culture chamber 3. A through hole is provided at the lower end of the culture chamber 3. The side wall of one end of the discharge plate 5 is tightly fitted with the inner wall of the through hole. A sealing strip 10 is provided on the side wall of one end of the discharge plate 5. A pull rod 11 is fixedly installed at one end of the discharge plate 5. The end of the storage frame 9 is through the pull rod 11, and a return spring 12 is sleeved on it. One end of the return spring 12 is fixedly connected to the inner wall of the storage frame 9. It should be noted that when mixing and feeding is required, two workers need to pull the pull rod 11 simultaneously to make the discharge plate 5 slide inside the storage frame 9. At this time, the through hole at the lower end of the culture chamber 3 is opened, which facilitates the feeding and guiding of the mixed bacterial culture substrate. It should be noted that the sealing strip 10 is made of rubber, which can enhance the sealing between the discharge plate 5 and the through hole.

[0024] The feeding assembly 4 includes a spiral feeding frame 401, which is rotatably engaged inside the culture chamber 3. The top of the spiral feeding frame 401 extends through the top of the culture chamber 3. A driven gear 402 is fixedly installed on the top of the spiral feeding frame 401. A driving gear 403 is rotatably engaged on the top surface of the culture tank 1. There are multiple driven gears 402, and the driving gears 403 mesh with each other for transmission. A feeding motor 404 is fixedly installed on the upper surface of the driving gear 403. A motor housing 405 is fitted around the feeding motor 404. The motor housing 405 is connected to the culture tank. The upper surfaces of body 1 are fixedly connected to each other. It should be noted that after the staff pulls the discharge plate 5, the staff controls the pusher motor 404 to start through the external controller, which enables the pusher motor 404 to drive the drive gear 403 to rotate. At this time, the drive gear 403 drives the driven gear 402 to rotate. At this time, multiple driven gears 402 start to rotate. Through the driven gears 402, the spiral pusher frame 401 can be rotated, which facilitates the rapid falling of the Chinese medicine substrate and prevents the Chinese medicine substrate from remaining stationary without external force, which is not conducive to the mixing of the inoculum.

[0025] An air inlet pipe 13 is connected to the lower end of the fermentation tank 2, and an air exchange pipe 14 is connected to the upper end of the fermentation tank 2. A support frame 15 is fixedly installed on the outer wall of the fermentation tank 2 to support the fermentation tank 2. It should be noted that, through the setting of the air inlet pipe 13 and the air exchange pipe 14, the bottom air inlet pipe 13 can be connected to sterile air, nitrogen or a specific mixed gas to control dissolved oxygen (DO); the top air exchange pipe 14 is connected to the condenser and the exhaust gas treatment device to realize gas exchange and maintain the tank pressure of the fermentation tank 2. The support frame 15 ensures the overall stability.

[0026] The stirring assembly 6 includes a main rod 601, which is rotatably engaged with the bottom of the fermentation tank 2. Stirring frames 602 are evenly fixedly installed on the outer circumference of the main rod 601. A rotating stirring frame 603 is rotatably installed inside the stirring frame 602. A bevel gear 604 is fixedly installed at one end of the rotating frame. A bevel gear ring 605 is fixedly installed on the inner circumference of the fermentation tank 2. The bevel gear 604 and the bevel gear ring 605 mesh and drive each other. A cross-shaped insertion slot 606 is provided on the main rod 601. A drive rod 607 is inserted into the inside of the culture tank 1. The lower end of the drive rod 607 is inserted into the cross-shaped insertion slot 606. A drive motor 608 is fixedly installed on the upper end of the drive rod 607. The drive motor 608 is connected to the culture tank 1 via a motor frame. It should be noted that the main rod 601 is rotated by the drive motor 608 through the drive rod 607 and the cross-shaped insertion slot 606. The main rod 601 rotates, causing the stirring frame 602 to revolve around the central axis of the fermentation tank. Each stirring frame 602 contains an independent rotating stirring rack 603, one end of which is equipped with a bevel gear 604. The bevel gear 604 meshes with a bevel gear ring 605 fixed to the tank wall. When the main rod 601 revolves, the bevel gear 604 rolls along the bevel gear ring 605, thereby driving each rotating stirring rack 603 to rotate in the opposite direction around its own axis. This motion generates an extremely complex and efficient flow field, which can fully shear, convection and diffusion mix the high viscosity and multi-solid traditional Chinese medicine fermentation mash, promoting the homogenization of cells, substrate, oxygen and metabolites, far superior to traditional single stirring. The culture tank 1 and the fermentation tank 2 are connected by bolts, and the cross-shaped plug-in connection between the drive rod 607 and the main rod 601 is a quick-installation design, which facilitates the separation of the upper culture tank 1 and the lower fermentation tank 2 for independent cleaning, sterilization or maintenance.

[0027] The liquid discharge assembly 7 includes liquid discharge holes 701, which are evenly distributed at the bottom of the fermentation tank 2. A discharge cone frame 702 is rotatably engaged with the lower end of the fermentation tank 2. The top of the discharge cone frame 702 is provided with a liquid guide hole 703 that aligns with the liquid discharge holes 701 one by one. A discharge pipe 704 is fixedly connected to the lower end of the discharge cone frame 702. A discharge valve 705 is provided on the discharge pipe 704. The liquid discharge holes 701 are evenly distributed at the bottom of the fermentation tank. The discharge cone frame 702 is rotatably sleeved on the bottom of the tank via bearings. The liquid guide holes 703 at its top correspond to the liquid discharge holes 701. Rotating the discharge cone frame 702... 02. Align all liquid guiding holes 703 with all liquid outlet holes 701 to quickly discharge all liquid. Rotate to align some holes for mid-process sampling or discharge of some supernatant. Install a filter screen in the discharge pipe 704 and rotate to open only a small number of bottom holes. After the stirring has basically stopped, use hydrostatic pressure to achieve preliminary solid-liquid separation. Collect the filtrate first. The rotary motor 708 drives the rotary gear 706 through the rotary gear 709 to precisely control the rotation angle of the discharge cone frame 702, thereby controlling the opening and closing state and opening degree of the liquid guiding holes 703, realizing the automation and precise control of the liquid discharge process.

[0028] The liquid discharge assembly 7 also includes a rotating toothed tooth 706, which is uniformly and fixedly installed on the upper circumferential outer wall of the discharge cone frame 702. A motor plate 707 is fixedly installed on the lower outer wall of the fermentation tank 2. A rotary motor 708 is fixedly installed on the lower surface of the motor plate 707. A rotary gear 709 is fixedly installed at the output end of the rotary motor 708. The rotary gear 709 and the rotating toothed tooth 706 mesh with each other for transmission. It should be noted that the rotary motor 708 drives the rotating toothed tooth 706 through the rotary gear 709, which can precisely control the rotation angle of the discharge cone frame 702, thereby controlling the opening and closing state and opening degree of the liquid guide hole 703, realizing the automation and precise control of the liquid discharge process.

[0029] Working principle: Phase 1: Preparation and Loading Pretreatment: The Chinese herbal medicine substrate is crushed, homogenized, and sterilized at high temperature (e.g., 121℃ for 20 minutes). Then, by opening the sealing door 16 at the top of each culture chamber 3, it is quantitatively loaded into each independent culture chamber 3 of the upper culture tank 1. Each culture chamber 3 can be used as an independent culture medium for different bacterial strains.

[0030] Through the same sealing door 16 or a dedicated inoculation port, the target bacterial strain (e.g., mold in chamber A, yeast in chamber B, and lactic acid bacteria in chamber C) is introduced into each culture chamber 3 that has been filled with sterilized substrate. Then all sealing doors 8 are closed, and the sealing doors 8 can be connected to the culture tank 1 through locks.

[0031] The external temperature control system connected to the device is activated (through jacket circulation) to provide an independent and suitable growth temperature for each culture chamber 3. At the same time, sterile ventilation can be provided to each chamber as needed (a ventilation tube can be connected to the top of each culture chamber 3) to begin independent activation and propagation of the strain. During this stage, the discharge plate 5 at the bottom of each chamber is closed under the action of the reset spring 12 to ensure a seal.

[0032] Phase Two: Controlled Vaccination and Transfer Opens the Channel When the bacterial strains in each chamber grow to the required biomass or are in a specific growth stage, they can be inoculated according to the process requirements. The operator (or the automated actuator) simultaneously or sequentially pulls the corresponding chamber's lever 11 outward to overcome the spring force and pull the discharge plate 5 into the side storage frame 9, thereby opening the through hole at the bottom of the chamber. The design of the sealing strip 10 ensures airtightness when closed.

[0033] After the through hole is opened, the pusher motor 404 is started immediately. The motor drives the drive gear 403 to rotate, and through gear meshing, it synchronously drives all driven gears 402 and the connected spiral pusher frame 401 to rotate. The spiral pusher frame 401 pushes the inoculum-substrate mixture in the chamber smoothly and continuously downward, so that it falls into the fermentation tank 2 in the lower layer through the through hole, thereby realizing the synchronous mechanical inoculation of multiple inoculum species, or the sequential inoculation can be realized by controlling the start and stop sequence of the pull rod 11 and the motor. The process is closed, which greatly reduces the risk of contamination.

[0034] Third stage: Primary fermentation and mixing of ingredients Once the inoculum and the traditional Chinese medicine substrate have all entered the fermentation tank 2, the drive motor 608 is started. The drive motor 608 drives the main rod 601 to rotate through the drive rod 607 and the cross-shaped insertion slot 606, causing the stirring frame 602 fixed on the main rod 601 to revolve around the central axis of the tank.

[0035] The bevel gear 604 at the end of the rotating stirring frame 603 in each stirring frame 602 meshes with the bevel gear ring 605 fixed to the tank wall. During the revolution, the bevel gear 604 rolls along the gear ring, forcing each rotating stirring frame 603 to rotate in the opposite direction around its own axis at the same time.

[0036] This stirring creates a complex and efficient three-dimensional flow field, which can achieve vigorous and uniform mixing of high-viscosity, multi-solid-phase Chinese medicine mash in a short time, ensuring that the microbial community, nutrients and dissolved oxygen are highly homogenized.

[0037] While stirring, sterile air or a specific gas is introduced through the air inlet pipe 13 at the bottom to control dissolved oxygen, while the air exchange pipe 14 at the top maintains the pressure difference and discharges waste gas. The external temperature control system continuously provides precise temperature control for the fermentation tank 2, creating the best synergistic fermentation environment.

[0038] Phase 4: Product Collection and Equipment Maintenance with Flexible Liquid Discharge After fermentation, the liquid discharge component 7 can be operated as needed to start the rotary motor 708. Through the meshing of the rotary gear 709 and the rotary teeth 706, the discharge cone frame 702 can be rotated precisely.

[0039] Rotate the conical frame to align all liquid guide holes 703 with all liquid outlet holes 701 at the bottom of the tank, open the discharge valve 705 to discharge all liquid, and the solid and liquid are initially separated. After fermentation is completed, the connecting bolts can be loosened to separate the culture tank 1 from the fermentation tank 2. The drive rod 607 can be pulled out from the cross-shaped insertion slot 606 to facilitate thorough CIP cleaning and sterilization of each component (such as steam sterilization and ultraviolet irradiation) to prepare for the next batch of fermentation.
