Description

[0001] The invention belongs to the technical field of microbial fermentation, and in particular relates to a mixing device for microbial fermentation. Background Art

[0002] In the field of microbial fermentation technology, mixing devices, as key equipment, play a vital role in ensuring uniform mixing of materials during the fermentation process, improving fermentation efficiency and product quality. With the continuous development of biotechnology, microbial fermentation processes are increasingly used in food, medicine, chemical industry and other fields, and the performance requirements for mixing devices are also increasing.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The rotation of the driving motor drives the spiral stirring rod to perform efficient stirring. The spiral design of the spiral stirring rod significantly enhances the ability of the material to flip up and down, and the rotating connection between the movable rod and the sleeve ensures that the stirring range can cover all areas of the tank. In addition, the belt drive method of the driving wheel and the transmission wheel not only reduces vibration and noise, but also improves the energy transfer efficiency, achieves full mixing and uniform contact of the material, and is suitable for microbial fermentation processes that require high mixing uniformity, significantly improving fermentation efficiency and product quality.

[0020] (2) Dynamic defoaming treatment is achieved during the fermentation process by adding components such as a sleeve plate, a fixed ring, a connecting rod, a connecting pipe, a mounting rod, a compression spring, a fixed plate, a capillary and a second connecting column. The fixed plate rotates synchronously with the stirring system and generates up and down vibrations through the relative movement of the first connecting column and the second connecting column. The vibrations are transmitted to the capillary at the bottom of the fixed plate, and the bubbles generated during the fermentation process are effectively broken by the microporous structure of the capillary. This not only solves the problems of decreased efficiency and pollution risk caused by foam accumulation in traditional fermentation processes, but is also particularly suitable for microbial fermentation systems that are prone to foaming. Through the dual effects of mechanical vibration and microporous crushing, the stability and controllability of the fermentation process are significantly improved, providing a more efficient and stable mixing environment for microbial fermentation.

[0021] (3) Through the storage box, feed pipe, right-angle connecting pipe, air pump, outlet pipe, annular pipe and connecting pipe and other components, the defoaming agent can be accurately injected and efficiently utilized. The defoaming agent flows to the top of the capillary through the right-angle connecting pipe and is evenly sprayed to the liquid surface when the capillary shakes, effectively inhibiting the formation of foam. At the same time, the compressed air output by the air pump can also backwash the capillary and the right-angle connecting pipe through the same pipeline to remove residual defoaming agent and prevent micropore blockage, thereby ensuring the efficient utilization of the defoaming agent and maintaining the long-term patency of the capillary system through the gas backwash cleaning mechanism. In addition, precise control of each component is achieved through the control panel, the observation glass facilitates real-time monitoring of the fermentation status, the discharge pipe is equipped with a valve to control the discharge, and the support column provides a stable bottom support, thereby improving the reliability and service life of the device, which is particularly suitable for long-term fermentation processes that require continuous defoaming.

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1:

[0032] See also Figures 1 to 7 As shown, a mixing device for microbial fermentation includes: a mixing tank body 1;

[0033] A sealing cover 2 is overlapped on the top of the mixing tank body 1, a mounting frame 3 is fixedly connected to the top of the sealing cover 2, and a driving motor 4 is fixedly connected to the inner wall of the mounting frame 3;

[0034] A driving rod 5 is installed at the output end of the driving motor 4, the bottom end of the driving rod 5 is fixedly connected to the connecting rod 6, the front end of the connecting rod 6 is fixedly connected to the sleeve 7, the inner wall of the sleeve 7 is rotatably connected to the movable rod 8, the surface of the driving rod 5 is rotatably connected to the driving wheel 9, the surface of the driving wheel 9 is rotatably connected to the transmission belt 10, the inner wall of the transmission belt 10 is rotatably connected to the transmission wheel 11, and the bottom of the transmission wheel 11 is fixedly connected to the top of the movable rod 8, and the bottom end of the movable rod 8 is fixedly connected to the spiral stirring rod 12.

[0035] When in use, the mixing tank body 1 serves as the core container for carrying the fermentation material, and the top is sealed by the sealing cover 2 to achieve a closed environment to prevent contamination; the mounting frame 3 fixes the drive motor 4 to provide a power source; the drive motor 4 drives the drive rod 5 to rotate, and the drive rod 5 is linked to the sleeve tube 7 through the connecting rod 6, so that the movable rod 8 rotates in the sleeve tube 7; the drive wheel 9 drives the transmission wheel 11 through the transmission belt 10, and further drives the spiral stirring rod 12 at the bottom of the movable rod 8 to rotate, forming a multi-stage stirring structure. The spiral stirring rod 12 enhances the ability of the material to flip up and down through the spiral design, and the rotating connection between the movable rod 8 and the sleeve tube 7 ensures that the stirring range covers all areas of the tank body. The belt drive mode of the drive wheel 9 and the transmission wheel 11 reduces vibration and noise, while improving the energy transfer efficiency, achieving full mixing and uniform contact of the materials, solving the problems of uneven stirring and low efficiency of traditional fermentation devices, and is particularly suitable for microbial fermentation processes that require high mixing uniformity. In addition, the overlap design of the sealing cover 2 and the mixing tank body 1 facilitates disassembly and cleaning, and the special shape of the spiral stirring rod 12 can effectively avoid material deposition, significantly improving fermentation efficiency and product quality.

[0036] Example 2:

[0037] See also Figures 1 to 7 As shown, the bottom end of the sleeve tube 7 is fixedly connected to a sleeve disk 13, the inner wall of the sleeve disk 13 is rotatably connected to a fixing ring 14, and the inner wall of the fixing ring 14 is fixedly connected to the surface of the movable rod 8, the surface of the fixing ring 14 is fixedly connected to multiple groups of connecting rods 15, the bottom of the connecting rod 15 is fixedly connected to two connecting tubes 16, the bottom end of the connecting tube 16 is inserted with a mounting rod 17, and the inner wall of the mounting rod 17 is inserted with a compression spring 18, and the top of the compression spring 18 is fixedly connected to the inner top wall of the connecting tube 16, the bottom end of the mounting rod 17 is fixedly connected to a fixing disk 19, the top of the fixing disk 19 is fixedly connected to multiple groups of first connecting columns 20, and a capillary 21 arranged in a ring shape is fixedly connected at the bottom edge of the fixing disk 19, the inner wall of the sleeve disk 13 is fixedly connected to multiple groups of second connecting columns 22, and the second connecting columns 22 are arranged above the first connecting columns 20.

[0038] During use, the socket disk 13 serves as the core support structure, and its inner wall is linked to the movable rod 8 through the fixed ring 14, so that the fixed disk 19 can rotate synchronously with the stirring system; the connecting rod 15 connects the fixed ring 14 to the connecting tube 16, and the inside of the connecting tube 16 forms an elastic connection with the mounting rod 17 through the compression spring 18, so that the fixed disk 19 can vibrate up and down during rotation; the first connecting column 20 is fixedly connected to the fixed disk 19 and rotates with it, while the second connecting column 22 is fixed to the inner wall of the socket disk 13 and remains stationary. The relative movement of the two generates mechanical vibration; the capillary tubes 21 are distributed in an annular shape on the bottom edge of the fixed disk 19. When the fixed disk rotates and vibrates, the microporous structure of the capillary tubes 21 can effectively break up the bubbles generated during the fermentation process, so that while the device is stirring and mixing, the rotation and vibration of the fixed disk 19 drive the capillary tubes 21 to generate high-frequency disturbances on the liquid surface, thereby achieving uniform mixing of the materials and completing efficient dynamic defoaming treatment, solving the problems of efficiency reduction and pollution risk caused by foam accumulation in traditional fermentation processes, and is particularly suitable for microbial fermentation systems that are prone to foaming.

[0039] Example 3:

[0040] See also Figures 1 to 7 As shown, the inner wall of the fixed disk 19 is fixedly connected to a storage box 23, the top of the fixed disk 19 is fixedly connected to a feed pipe 24, the surface of the storage box 23 is fixedly connected to a right-angle connecting pipe 25, and the surface of the right-angle connecting pipe 25 is fixedly connected to the inner wall of the socket disk 13, the bottom end of the right-angle connecting pipe 25 is fixedly connected to the top of the capillary 21, the top of the fixed disk 19 is fixedly connected to an air pump 26, the output end of the air pump 26 is equipped with an air outlet pipe 27, the bottom end of the air outlet pipe 27 is fixedly connected to an annular pipe 28, the bottom end of the annular pipe 28 is fixedly connected to multiple groups of connecting pipes 29, and the bottom end of the connecting pipe 29 is fixedly connected to the surface of the right-angle connecting pipe 25, the transmission wheel 11 The top of the mixing tank body 1 is fixedly connected to a positioning rod 30, the top of the positioning rod 30 is fixedly connected to a bearing ring, the surface of the bearing ring is rotatably connected to a positioning ring 31, and the top of the positioning ring 31 is fixedly connected to the bottom of the sealing cover 2, the top of the sealing cover 2 is fixedly connected to an injection pipe 32, the surface of the mixing tank body 1 is fixedly connected to a control panel 33, the surface of the mixing tank body 1 is located at the top of the control panel 33 and is fixedly connected to an observation glass 34, the bottom of the mixing tank body 1 is fixedly connected to a discharge pipe 35, the inner wall of the discharge pipe 35 is rotatably connected to a valve, the bottom of the mixing tank body 1 is fixedly connected to multiple groups of support columns 36, and the bottom ends of the support columns 36 are fixedly connected to anti-slip pads.

[0041] When in use, the storage box 23 serves as a defoaming agent storage container, and the precise injection of the defoaming agent is achieved through the feeding pipe 24 connected at the top; the right-angle connecting pipe 25 connects the storage box 23 with the annularly distributed capillary tube 21 to form a defoaming agent delivery network, and the air pump 26 serves as the core power source. The compressed air it outputs enters the annular tube 28 through the air outlet pipe 27, and is then diverted to each right-angle connecting tube 25 through multiple groups of connecting tubes 29, and finally ejected from the micropores of the capillary tube 21. The system has a dual function: during the defoaming operation, the defoaming agent flows from the storage box 23 through the right-angle connecting tube 25 to the capillary tube 21 by gravity, and participates in the defoaming of the liquid surface; in the cleaning stage, the high-pressure gas generated by the air pump 26 Back flushing through the same pipeline can effectively remove the defoaming agent residue in the capillary 21 and the right-angle connecting pipe 25 to prevent clogging of the micropores. The positioning rod 30 and the positioning ring 31 ensure the stable operation of the transmission wheel 11. The injection pipe 32 is used for adding the main material. The control panel 33 realizes precise control of each component. The observation glass 34 facilitates real-time monitoring of the fermentation status. The discharge pipe 35 is equipped with a valve to control the discharge. The support column 36 provides a stable bottom support. This integrated design not only ensures the efficient utilization of the defoaming agent, but also maintains the long-term patency of the capillary system through the gas backflushing cleaning mechanism, significantly improving the reliability and service life of the device. It is particularly suitable for long-term fermentation processes that require continuous defoaming.

[0042] Example 4:

[0043] See also Figures 1 to 7 As shown, in the beer brewing industry, efficient yeast cultivation and fermentation are key production links. Traditional fermentation tanks have problems such as uneven mixing and foam accumulation affecting fermentation efficiency. This mixing device for microbial fermentation significantly improves the uniformity of yeast cultivation and fermentation efficiency through an innovative stirring and defoaming system, and is suitable for large-scale yeast expansion and fermentation production in breweries.

[0044] Check the sealing of the mixing tank body 1 and ensure that the sealing cover 2 is tightly overlapped with the tank body to prevent external contamination.

[0045] Yeast culture medium (such as malt juice) is added into the mixing tank body 1 through the injection pipe 32, and the liquid level is controlled within the safe range indicated by the observation glass 34.

[0046] Liquid defoaming agent is injected into the storage box 23 from the feeding pipe 24 , and the defoaming agent is pre-filled into the micropores of the capillary tube 21 through the right-angle connecting pipe 25 .

[0047] The driving motor 4 is started through the control panel 33 , and the driving motor 4 drives the driving rod 5 to rotate, and the driving rod 5 drives the movable rod 8 to rotate through the connecting rod 6 and the sleeve 7 .

[0048] The spiral stirring rod 12 at the bottom of the movable rod 8 starts to rotate, and its spiral structure pushes the culture medium up and down to ensure that the yeast is fully in contact with the nutrients.

[0049] At the same time, the driving wheel 9 drives the driving wheel 11 through the driving belt 10, so that the rotation speed of the movable rod 8 is further increased, forming a multi-stage stirring effect.

[0050] The fixed disk 19 rotates synchronously with the movable rod 8. The relative movement of the first connecting column 20 and the second connecting column 22 causes the fixed disk 19 to generate high-frequency vibration, driving the capillary 21 to mechanically break the foam on the liquid surface.

[0051] The defoaming agent flows from the storage box 23 to the capillary tube 21 through the right-angle connecting pipe 25 and is evenly sprayed onto the liquid surface to further suppress the generation of foam.

[0052] After each batch of fermentation is completed, the air pump 26 is started, and the high-pressure gas is reversely flushed through the outlet pipe 27, the annular pipe 28 and the connecting pipe 29 to flush the right-angle connecting pipe 25 and the capillary tube 21 to remove residual defoaming agent and prevent micropores from being blocked.

[0053] The fermentation liquid status is monitored in real time through the observation glass 34, and the control panel 33 adjusts the speed of the drive motor 4 to meet the requirements of different fermentation stages.

[0054] After the fermentation is completed, the valve of the discharge pipe 35 is opened to guide the fermentation liquid to the next process.

[0055] The anti-skid pads of the support column 36 ensure the stability of the equipment during operation and avoid vibration interference.

[0056] Working Principle: During operation, the mixing tank is sealed with a sealing cap to ensure a clean, pollution-free fermentation environment. After the drive motor is activated, its output drives the drive rod to rotate. This rod is linked to the sleeve via a connecting rod, causing the movable rod to rotate within the sleeve. Simultaneously, a drive wheel on the rod's surface rotates via a transmission belt, further driving the spiral stirring rod at the bottom of the movable rod to rotate and stir. The spiral design of the stirring rod effectively propels the materials in the fermentation tank up and down, achieving initial mixing.

[0057] The socket disc at the bottom of the sleeve tube serves as the core support structure. Linked to the movable rod via a fixed ring, the fixed disc rotates synchronously with the stirring system. A connecting rod connects the fixed ring to the connecting tube, while the mounting rod inside the connecting tube forms an elastic connection to the connecting tube via a compression spring. During the rotation of the fixed disc, the relative motion between the first connecting post at the top of the fixed disc and the second connecting post on the inner wall of the socket disc causes the fixed disc to vibrate up and down. This vibration is transmitted through the fixed disc to the capillary tube at its bottom. The microporous structure of the capillary tube effectively breaks up bubbles generated during the fermentation process under the action of the vibration, achieving dynamic defoaming treatment.

[0058] In addition, the storage box serves as a defoamer storage container, allowing precise injection of defoamer through the feed tube. The defoamer flows through the right-angle connecting tube to the top of the capillary tube and is evenly sprayed onto the liquid surface when the capillary tube shakes, further suppressing foam formation. When cleaning is required, the air pump starts, and the compressed air output enters the annular tube through the outlet pipe. It is then diverted to each right-angle connecting tube through the connecting pipe and finally ejected from the capillary micropores, achieving high-pressure gas backwash cleaning of the capillary tube and the right-angle connecting tube, preventing micropore blockage.

[0059] The entire device's operation is precisely controlled by a control panel, allowing the operator to adjust the drive motor speed to suit the needs of different fermentation stages. An observation glass facilitates real-time monitoring of the fermentation liquid's status, ensuring smooth progress. Upon completion, the liquid is discharged via a valve in the discharge pipe. The support columns and their anti-slip pads provide a secure base, ensuring stability during operation.
