Description

Technical Field

[0001] This invention belongs to the technical field of solid-state fermentation devices, and more specifically, it relates to a combined solid-state fermentation device for post-fermentation biogener. Background Technology

[0002] With the surge in demand for metabiotics in the feed industry and livestock farming, solid-state fermentation, as the core process for metabiotic production, places higher demands on the efficiency, precision, and versatility of equipment. However, current traditional solid-state fermentation equipment still faces multi-dimensional technical bottlenecks, making it difficult to meet the industry's development needs. Furthermore, existing solid-state fermentation devices have the following shortcomings:

[0003] Traditional equipment relies heavily on independent power sources (such as separate stirring motors and air pumps) for stirring, crushing, and aeration. This not only leads to complex equipment structures and redundant components (resulting in more dispersed failure points), but also makes it prone to asynchronous operation of various functions (such as stirring too fast while aeration lags behind). This causes a disconnect between material mixing and gas contact, increasing energy consumption and reducing operational stability. Traditional stirring is mostly unidirectional rotation, which easily leads to material stratification and low mixing uniformity (usually below 70%), creating local fermentation dead zones. On the other hand, for the 2-10mm lumps generated during fermentation, traditional crushing is mostly rigid impact, which easily damages the cell structure of the material, causing loss of active ingredients. Moreover, the lump crushing rate is less than 75%, and residual lumps can easily cause local hypoxic fermentation, affecting the uniformity of the product.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a combined solid-state fermentation device for biogenerogen after solid-state fermentation, in order to achieve a more practical and valuable purpose. Summary of the Invention

[0005] This invention provides a combined solid-state fermentation device for post-solid-state fermentation of biogener, which overcomes the above-mentioned defects in the prior art.

[0006] The purpose and efficacy of the combined solid-state fermentation device for post-fermentation biogener of the present invention are achieved by the following specific technical means:

An extrusion sleeve assembly is fixedly mounted below the rotating plate. The extrusion sleeve assembly includes an upper sleeve. An extrusion push rod is slidably mounted inside the upper sleeve. An air-inflating assembly is fixedly connected to the lower end of the extrusion push rod.

[0015] In a further technical solution, the inflation assembly includes an air-jet base plate with a cavity inside. A conical extrusion cylinder is fixedly installed below the air-jet base plate, and a fixed base plate is provided at the bottom of the conical extrusion cylinder. The fixed base plate communicates with the inner wall of the bottom of the fermentation tank.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This invention discloses a combined solid-state fermentation device for post-fermentation biogener. The device employs an improved design with a stirring blade assembly: it utilizes a combination of rotational and reciprocating three-dimensional motion with a bidirectional threaded rod; an X-shaped blade layout with inclined guide channels and rough, textured protrusions within the channels; and it shares a power source with the drive motor assembly and cleaning / crushing device for synchronized movement. This results in: 1. Improved material mixing uniformity, completely eliminating localized fermentation dead zones in traditional equipment and avoiding product quality differences caused by uneven mixing; 2. Shortened stirring time, and reduced energy consumption of independent motors due to the shared power design, leading to lower total energy consumption per fermentation cycle; 3. Adaptability to materials of different viscosities (such as semi-solid culture media and high-fiber plant-based materials). The rough, textured protrusions enhance adhesion to sticky materials, preventing material from sticking to the walls or agglomerating, and reducing material loss during cleaning.

[0021] This invention discloses a combined solid-state fermentation device for post-fermentation biosynthetic agents. Through a cleaning and crushing device, it utilizes an integrated structure comprising: "multiple funnel-shaped feed inlets in the feed box actively intercepting clumps," "an elastic, wear-resistant arc-shaped cloth cover that stretches and contracts with rotation, plus internal protrusions for initial crushing," and "a built-in impact crushing device (centrifugal sliding of crushed blocks + high-frequency collision with compression springs + a semi-arc first vertical crushing rod) to refine clumps." This results in: 1. A high clump crushing rate, completely solving the "localized anaerobic fermentation" problem caused by clump residue in traditional equipment, ensuring that each material particle can fully contact the bacteria and gas; 2. The flexible crushing method of the elastic arc-shaped cloth cover avoids the damage to the material's cell structure caused by traditional rigid crushing, ensuring the integrity of the fermentation substrate and improving the retention rate of post-fermentation biosynthetic active ingredients; 3. Components can be replaced individually (e.g., after the arc-shaped cloth cover wears down, only the cloth cover body needs to be replaced, without disassembling the entire device), shortening maintenance time and reducing maintenance costs; 4. Multiple funnel-shaped feed inlets can adapt to clumps of different sizes, improving interception efficiency compared to traditional single feed inlets and preventing clumps from spreading within the tank.

[0022] This invention discloses a combined solid-state fermentation device for post-fermentation metabolites. Through an aeration and extrusion assembly, it achieves the following through a coordinated design: "using the mechanical energy of the stirring blades to drive the extrusion sleeve assembly to complete piston pumping," "achieving uniform gas injection through the combination of a conical extrusion cylinder, a gas collection hood, and an air jet base plate," and "coordinating the disturbance of the air jet and rotating blade assembly." This results in: 1. Improved gas utilization, avoiding gas loss and waste caused by traditional static aeration, especially reducing oxygen supply in aerobic fermentation; 2. No need for an additional aeration pump, reducing the number of equipment components and size, saving laboratory installation space, reducing power source failure points, and lowering equipment failure rate; 3. Increased oxygen absorption rate during aerobic fermentation, accelerating bacterial reproduction, shortening the fermentation cycle, and increasing the content of short-chain fatty acids, antimicrobial peptides, and other active ingredients in the metabolites due to sufficient oxygen; 4. The uniform gas distribution design of the air jet base plate reduces gas concentration differences between different areas within the tank, avoiding fermentation abnormalities caused by localized gas excess or deficiency.

[0044] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0047] As attached Figure 1 To be continued Figure 11 As shown:

[0048] This invention provides a combined solid-state fermentation device for biogenerators after solid-state fermentation, including a combined fermentation tank 1. The combined fermentation tank 1 includes a first fermentation tank 11 and a second fermentation tank 12. An inner tank 18 is installed inside the first fermentation tank 11. The inner tank 18 is equipped with a stirring blade device 26, a cleaning and crushing device 25, and an aeration and extrusion assembly 3. A drive motor assembly 22 is fixedly installed above the stirring blade device 26, and the drive motor assembly 22 provides rotational power for the stirring blade device 26 and the cleaning and crushing device 25. Through the combined design of the two fermentation tanks, simultaneous fermentation of multiple batches or different strains can be achieved, improving equipment utilization. At the same time, the concentrated power output of the drive motor assembly 22 reduces the number of power sources and lowers equipment energy consumption and failure probability.

[0049] The stirring blade device 26 is driven by the drive motor assembly 22 to move up and down and rotate. A cleaning and crushing device 25 is provided on the outside of the stirring blade device 26. The cleaning and crushing device 25 works with the stirring blade device 26 to intercept and crush the internal lumps. The combined up-and-down movement and rotation of the stirring blade device 26 can greatly improve the uniformity of material mixing and avoid local fermentation dead zones. The synergistic effect of the cleaning and crushing device 25 and the stirring blade device 26 can promptly crush the lumps generated during fermentation, ensuring that the material is in full contact with the fermentation environment and improving fermentation efficiency.

[0050] When the stirring blade device 26 extends and retracts, it will compress the aeration extrusion component 3. After compression, the aeration extrusion component 3 will eject gas. The ejected gas will cooperate with the stirring blade device 26 to achieve a thorough mixing reaction. The stirring action and the aeration action are linked, so that the gas is evenly diffused in the flow field generated by the stirring, avoiding the problem of local gas accumulation in the traditional aeration method, improving the contact efficiency between gas and material, ensuring the stability of the gas environment required for fermentation, and thus improving the uniformity of fermentation products.

[0051] Preferred options are shown in the appendix. Figure 1 To be continued Figure 2 The first fermentation tank 11 includes a fermentation tank body 16. A lower support 19 is fixedly installed below the fermentation tank body 16, and a top cover is fixedly installed above the fermentation tank body 16. The top cover is equipped with a stirring drive assembly 2, a feed inlet 29, and a pressure relief valve 21. An inner tank 18 is fixedly installed inside the fermentation tank body 16. The inner tank 18 is equipped with a stirring blade device 26, a cleaning and crushing device 25, and an air-pressurizing assembly 3. The lower support 19 raises the height of the tank body off the ground, facilitating bottom pipeline operation and equipment maintenance. The top cover design ensures the tank body's sealing. The pressure relief valve 21 can adjust the pressure inside the tank in real time to prevent excessive pressure from affecting fermentation safety, while also timely discharging the waste gas generated during fermentation to maintain a stable internal environment. The independent setting of the inner tank 18 facilitates cleaning and replacement, improving the flexibility of equipment use.

[0052] Preferred options are shown in the appendix. Figure 4 To be continued Figure 8 The stirring drive assembly 2 includes a drive motor assembly 22 and a bidirectional threaded rod 221. A rotating blade assembly 23 is fixedly mounted on the surface of the bidirectional threaded rod 221. A stirring blade device 26 is fixedly mounted below the rotating blade assembly 23. The stirring blade device 26 includes a rotating sleeve 262. An X-shaped stirring blade 261 is fixedly connected to the surface of the rotating sleeve 262. The surface of the X-shaped stirring blade 261 is provided with multiple guide grooves, which are obliquely arranged and have rough, textured protrusions. The bidirectional threaded rod 221 drives the stirring blade device 26 to achieve up-and-down reciprocating motion, which, combined with the rotational motion, forms a three-dimensional stirring trajectory. The structural design of the X-shaped stirring blade 261 increases the contact area with the material. The oblique guide grooves guide the material to form a spiral flow, improving the uniformity of stirring. The rough, textured protrusions enhance the friction on the material, preventing the material from slipping on the blade surface and further improving the stirring effect.

[0053] Preferred options are shown in the appendix. Figure 6 To be continued Figure 8The cleaning and crushing device 25 includes a fixed guide rod 251 and a crushing component 252. The fixed guide rod 251 is fixedly connected to the rotating blade assembly 23. The crushing component 252 is fixedly connected to both ends of the fixed guide rod 251. The crushing component 252 includes a feed box 2523. The feed box 2523 has multiple discharge ports 2524 at its feed inlet. Arc-shaped cloth covers 2522 are installed on both sides of the rear end of the feed box 2523. The upper and lower ends of the arc-shaped cloth covers 2522 are fixedly installed with... An impact crushing device 5 is installed inside the end cap 2521 and the arc-shaped cloth cover 2522; the fixed guide rod 251 ensures that the crushing component 252 moves synchronously with the rotating blade component 23; multiple discharge ports 2524 expand the interception range of agglomerated materials; the arc-shaped cloth cover 2522 can undergo elastic deformation with movement to enhance the wrapping and crushing effect of agglomerated materials; the internal impact crushing device 5 realizes secondary fine crushing of agglomerated materials to avoid large pieces of material remaining and affecting the uniformity of fermentation.

[0054] Preferred options are shown in the appendix. Figure 10 To be continued Figure 11 The impact crushing device 5 includes two sets of second vertical crushing rods 55, with a through-axis 51 fixedly installed between the two sets of second vertical crushing rods 55. Several sets of first vertical crushing rods 54 are arrayed on the surface of the two sets of second vertical crushing rods 55. The outer protrusion of the first vertical crushing rods 54 forms a semi-arc shape. Two sets of crushing blocks 53 are movably installed on the surface of the through-axis 51. A compression spring 52 is provided between the two sets of crushing blocks 53 and the two sets of second vertical crushing rods 55. The semi-arc protrusion of the first vertical crushing rods 54 can reduce the hard impact damage to the agglomerates. At the same time, the arc surface guides the agglomerates to gather towards the center. The crushing blocks 53 reciprocate under the action of centrifugal force and compression spring 52, forming high-frequency collision crushing of the agglomerates. Combined with the array distribution of the second vertical crushing rods 55, a multi-angle and multi-level crushing effect is achieved, improving the crushing efficiency and crushing fineness of the agglomerates.

[0055] Preferred options are shown in the appendix. Figure 6 To be continued Figure 9Below the stirring blade device 26, there is an air-pressing assembly 3. The air-pressing assembly 3 includes a rotating plate assembly 31 and an extrusion sleeve assembly 32. The rotating plate assembly 31 includes a lifting filter plate and a rotating plate. The lifting filter plate is fixedly connected to the X-shaped stirring blade 261. The rotating plate is rotatably mounted on the surface of the lifting filter plate. The extrusion sleeve assembly 32 is fixedly mounted below the rotating plate. The extrusion sleeve assembly 32 includes an upper sleeve 321. An extrusion push rod 322 is slidably mounted inside the upper sleeve 321. An air-pressing assembly 4 is fixedly connected to the lower end of the extrusion push rod 322. The lifting filter plate moves synchronously with the X-shaped stirring blade 261, driving the rotating plate to achieve vertical displacement, thereby driving the extrusion sleeve assembly 32 to complete the piston-like suction action. The mechanical energy of the stirring action is converted into air-pressing power, eliminating the need for an additional air-pressing drive device, simplifying the equipment structure, and reducing energy consumption. The rotating connection design between the rotating plate and the lifting filter plate ensures that the extrusion action is not disturbed by the rotational motion, improving the stability of the assembly operation.

[0056] Preferred options are shown in the appendix. Figure 6 To be continued Figure 8 The inflation assembly 4 includes an air jet base plate 27 with an internal cavity. A conical extrusion cylinder 41 is fixedly installed below the air jet base plate 27. A fixed base plate 43 is provided at the bottom of the conical extrusion cylinder 41, which communicates with the inner wall of the bottom of the fermentation tank 16. A gas collection hood 42 is connected between the interior of the conical extrusion cylinder 41 and the interior of the air jet base plate 27. An air jet nozzle 28 is fixedly installed on the surface of the air jet base plate 27 and communicates with the interior of the fermentation tank 16. The structural design of the conical extrusion cylinder 41 can enhance the gas compression effect and increase the air jet pressure. The gas collection hood 42 realizes the centralized guidance of gas and avoids gas leakage loss. The cavity design of the air jet base plate 27 makes the gas evenly distributed to each air jet nozzle 28, ensuring a balanced gas supply in each area of ​​the tank. The air jet nozzle 28 is directly connected to the interior of the tank, reducing gas transmission resistance and improving gas utilization.

[0057] Preferred options are shown in the appendix. Figure 1 To be continued Figure 2 The first fermenter 11 and the second fermenter 12 are provided with an air inlet valve 14 and an exhaust valve 15 at the bottom. A sterile pipe 13 is fixedly connected between the first fermenter 11 and the second fermenter 12, and the sterile pipe 13 is connected in series with the second fermenter 12.

[0058] Preferred options are shown in the appendix. Figure 1 To be continued Figure 2The fermentation tank body 16 is provided with a feeding port 24 on the outside and a feeding door 17 on the outside. The feeding door 17 and the air inlet valve 14 are located on one side. The feeding port 24 is located on the outside to facilitate material feeding operations. The rotating feeding door 17 ensures the sealing of the tank after feeding. The feeding door 17 and the air inlet valve 14 located on the same side facilitate centralized operation by operators and improve the ease of use of the equipment.

[0059] Preferred options are shown in the appendix. Figure 1 To be continued Figure 2 Each connection point between the sterile pipe 13 and the first fermenter 11 and the second fermenter 12 is equipped with an air inlet valve 14 and an exhaust valve 15. The air inlet valve 14 is connected to an external air source, and the exhaust valve 15 is connected to an external waste gas treatment device. The air inlet valve 14 and the exhaust valve 15 are electrically connected to the pressure sensor inside the jet base plate 27, which can automatically start or stop the air supply or exhaust according to the pressure value inside the jet base plate 27. One-way control valves are provided on the sterile pipe 13 at the positions corresponding to the first fermenter 11 and the second fermenter 12. The one-way control valves can control the flow of bacteria between the first fermenter 11 and the second fermenter 12 through the sterile pipe 13.

[0060] Specific usage of this invention:

[0061] When using this equipment, first move it to a laboratory that meets the requirements for solid-state fermentation (ensure that the ambient temperature and humidity meet the fermentation conditions). Then, manually rotate and open the feeding door 17 (the rotating connection structure between the feeding door 17 and the fermentation tank body 16 allows for quick opening and closing while ensuring a tight seal). Feed the required fermentation materials (such as culture medium, inoculum, etc.) into the fermentation tank body 16 through the feeding port 24. The materials will naturally fall onto the air jet bottom plate 27 (the surface of the air jet bottom plate 27 is flat and has evenly distributed air jets 28, which can prevent material accumulation and blockage). After feeding the materials, close the feeding door 17, then turn on the power to start the equipment and begin the stirring and mixing fermentation program. Traditional solid-state fermentation tanks rely solely on unidirectional stirring, which easily leads to material stratification and uneven mixing. Furthermore, the gas is mostly introduced statically, resulting in insufficient contact with the material and a gas mixing compliance rate of less than 60%, ultimately causing incomplete fermentation and significant differences in product quality. This equipment, through a multi-component collaborative design, effectively solves the above problems. During stirring, if additional material needs to be added, the 29 valve can be opened to add material from top to bottom.

[0062] Subsequently, when the equipment is running, the drive motor assembly 22 is first started via the control panel (the drive motor assembly 22 is a servo motor, which can precisely control the speed and direction). When the drive motor assembly 22 is powered on and rotates, its output shaft drives the bidirectional threaded rod 221 to rotate synchronously (the thread structure on the surface of the bidirectional threaded rod 221 matches the threaded hole in the rotating blade assembly 23), thereby driving the rotating blade assembly 23 to move up and down along the axial direction of the bidirectional threaded rod 221. At the same time, the rotating blade assembly 23 drives the stirring blade device 26 fixedly connected below and the cleaning and crushing device 25 fixed on the side to rotate synchronously (the three achieve synchronous power transmission through a fixed structure to ensure coordinated action). The stirring blade device 26 rotates while reciprocating up and down along the threaded trajectory of the bidirectional threaded rod 221 (the reciprocating stroke can be adjusted according to the amount of material by motor parameters). During the movement, the X-shaped stirring blade 261 generates lateral shearing force through rotation and longitudinal tumbling force through up and down movement. The combined lateral and longitudinal forces can drive the material to form a three-dimensional flow trajectory, completely breaking the limitation of unidirectional movement in traditional stirring and achieving a thorough stirring effect (the material mixing uniformity can reach more than 95% according to tests).Furthermore, when the X-shaped stirring blade 261 moves downward, the lifting filter plate fixedly connected to its bottom (the lifting filter plate and the X-shaped stirring blade 261 are integrally formed, with high strength and not easily deformed) moves downward simultaneously, generating a downward squeezing force on the rotating plate assembly 31 below (the rotating plate assembly 31 and the lifting filter plate are rotatably connected, and can rotate with the X-shaped stirring blade 261 without affecting the vertical displacement). After being subjected to force, the rotating plate assembly 31 pushes the lower extrusion sleeve assembly 32 to move—the extrusion push rod 322 slides downward along the inner wall of the upper sleeve 321 (the upper sleeve 321 and the extrusion push rod 322 form a piston structure, and the inner wall is provided with a sealing ring to ensure no gas leakage), realizing the piston pulling action; when the extrusion push rod 322 extrudes downward, the conical extrusion cylinder 41 fixedly connected to its lower end (the conical structure can reduce the internal volume and improve the gas compression efficiency) is subjected to downward pressure, and the internal gas is rapidly compressed (the compressed gas pressure can reach 0.3-0.5MPa). The compressed gas passes through the collection tube connected to the top of the conical extrusion cylinder 41. The gas hood 42 (the gas collection hood has a funnel-shaped structure that can concentrate and guide dispersed gas) enters the cavity inside the jet bottom plate 27. When the gas pressure inside the cavity of the jet bottom plate 27 reaches the set threshold (monitored in real time by a pressure sensor), the gas is sprayed upward in a uniform airflow form through the jet nozzle 28, directly acting on the fermentation material above the jet bottom plate 27, thereby replenishing the gas supply to the fermentation material inside the inner tank 18 (the gas is oxygen or inert gas required for fermentation, which is set in advance according to the requirements of the strain). At the same time, during the rotation of the rotating blade assembly 23, the surface of its blades can generate a disturbance effect on the gas inside the tank, further dispersing the gas ejected from the jet nozzle 28 into tiny bubbles, increasing the contact area between the gas and the material (the bubble diameter can be reduced to 1-3 mm). Furthermore, through the blowing action of the rotating blade assembly 23, the bubbles are driven to diffuse with the material flow to various areas inside the tank, ultimately achieving the linkage between the up-and-down movement of the stirring blade device 26 and the gas injection, ensuring the full mixing and reaction of the material and gas during the fermentation process.

[0063] Subsequently, as the stirring blade device 26 moves up and down and rotates, the cleaning and crushing device 25 connected to its outer side via the fixed guide rod 251 also moves synchronously to intercept and collect the clumps in the material inside the tank (clumps with a diameter of 5-10 mm that are easily formed due to changes in moisture and temperature during fermentation). Specifically, the crushing component 252 of the cleaning and crushing device 25 generates centrifugal force as it rotates, attracting the surrounding clumps of material towards the feed box 2523. The clumps of material enter the crushing component 252 through multiple discharge ports 2524 at the feed inlet of the feed box 2523 (the discharge ports 2524 are funnel-shaped openings to increase the feeding range and prevent clogging). At the same time, the arc-shaped cloth cover 2522 (made of elastic and wear-resistant fabric that can deform elastically with centrifugal force) is subjected to the dual action of centrifugal force and material impact force during rotation, achieving irregular movement of stretching outward or contracting inward (deformation range can reach 5-8cm). This movement can reduce or expand the internal cavity space of the crushing component 252, squeezing and shaking the clumps of material inside. The inner surface of the arc-shaped cloth cover 2522 is provided with raised dots (the dots are 2-3mm in diameter and made of hard plastic). When the raised dots come into contact with the clumps of material, they can generate local compressive stress, initially destroying the clump structure. When the agglomerated material enters the crushing component 252, it first comes into contact with the crushing blocks 53 of the impact crushing device 5 (the crushing blocks 53 have an arc-shaped structure and a smooth surface, which can reduce material adhesion). The centrifugal force generated by the high-speed rotation causes the two sets of crushing blocks 53 to slide outward along the through-axis 51, squeezing the compression springs 52 on both sides (the elastic coefficient of the compression springs 52 can be selected according to the hardness of the agglomerated material). When the crushing blocks 53 slide to the maximum stroke, the compression springs 52 reach the maximum compression. Then, under the action of the spring force, the crushing blocks 53 return to the inward and collide with the agglomerated material at a high frequency (the collision frequency can reach 10-15 times / second). At the same time, the first vertical crushing rods 54 (the semi-arc protrusion structure can avoid scratching the material and increase the contact area) of the two sets of second vertical crushing rods 55 surface arrays produce multi-angle shearing action on the agglomerated material as the impact crushing device 5 rotates. Under the dual action, the agglomerated material can be completely crushed into fine particles with a diameter of less than 1 mm. The crushed material is discharged through the opening at the rear end of the crushing component 252 and re-enters the tank to mix with other materials (to avoid material residue after crushing). To ensure fermentation effectiveness, the equipment is set to start a mixing and crushing program every half hour, lasting 10 minutes each time (the program can be set independently through the control panel to adapt to the needs of different fermentation stages), ensuring that there are no lumps or residues throughout the fermentation process.

[0064] Gas supply within the conical extrusion cylinder 41 is achieved through the inlet valve 14—which is connected to an external gas source (such as a gas cylinder or air compressor) and can automatically open or close the gas supply based on the pressure sensor signal within the jet base plate 27 (automatic gas supply when the pressure is below 0.2 MPa and stops when it is above 0.5 MPa). Simultaneously, the exhaust valve 15 is connected to an external waste gas treatment device, which can discharge waste gases such as carbon dioxide and organic acids generated during fermentation in real time (the exhaust rate matches the inlet rate to maintain pressure balance within the tank), achieving coordinated control of dynamic gas supply and waste gas emission. In addition, the sterile pipe 13 (with a diameter of 100-150mm and a smooth inner wall for easy sewage discharge) connecting the first fermenter 11 and the second fermenter 12 not only enables centralized sewage discharge of multiple tanks (eliminating the need to operate each tank individually during cleaning, thus improving cleaning efficiency), but also allows for the flow of materials / microorganisms between tanks through valve control. When the fermentation in the first fermenter 11 reaches a certain stage, the connecting valve can be opened to allow the fermentation material in the tank to enter the second fermenter 12 through the sterile pipe 13, providing auxiliary microorganisms for the fermentation in the second fermenter 12, realizing multi-tank synergistic fermentation, and improving fermentation efficiency and product diversity.
