Description

Technical Field

[0001] The present invention belongs to the technical field of microbial fermentation reactors. Specifically, it particularly relates to a glutamic acid fermentation reactor device and its operation method. Background Art

[0002] Glutamic acid is an important amino acid, which has relatively large applications in the food field, animal feed field, and agricultural field. For example, glutamic acid can be used as a nutritional supplement to provide various amino acids required for animal growth, improve the flavor of feed and its attractiveness for feeding, and enhance the immunity of animals, etc. The most common way to synthesize glutamic acid is by using the microbial synthesis method, which mainly has the advantages of high production efficiency, high product purity, wide and cheap raw material sources, and being very friendly to the environment. During the fermentation process, it is necessary to pay attention to the preparation of nutrient components, the regulation of temperature, the stable supply of dissolved oxygen, etc., in order to ensure the efficient synthesis of glutamic acid. However, there is a lack of special reactors for glutamic acid fermentation on the market.

[0003] A Chinese patent with the publication number "CN118217916A" discloses a chemical reactor, including a reactor body. The reactor body includes an inner reactor body and an outer reactor body. There is an interlayer between the inner reactor body and the outer reactor body. There are turntables at the tops of the inner reactor body and the outer reactor body. There is an arc-shaped ring plate at the top of the outer reactor body. A cylinder is fixedly connected to the middle of the arc-shaped ring plate. A first circular groove is formed on one side of the turntable located in the arc-shaped bin. A first rotating block is rotatably connected in the first circular groove. A U-shaped tube is fixedly connected in the first rotating block. This device is used to solve the problem that the materials in the middle of the reactor body are far from the interlayer, resulting in poor heat transfer effect.

[0004] During the later use process, the following problems still exist in this device: 1. In order to achieve sufficient mixing of the materials, the stirring mechanism of the reactor needs to occupy a relatively large space inside the reactor; 2. The materials close to the inner wall of the interlayer need to be continuously stirred. There is a lack of mechanisms such as scraping plates in this device. In order to avoid coking, the paddles and stirring blades must maintain a high rotation speed to stir the materials close to the inner wall of the interlayer, consuming a large amount of electric power resources and easily affecting the continuation of the reaction. The relatively high shear force is likely to damage the formation conditions of the reactants. Summary of the Invention

Detailed implementation mode

[0017] The present invention will be further described below with reference to the accompanying drawings: In the paragraphs of detailed description, the orientation nouns involved are only for the convenience of those skilled in the art to understand the technical solutions recorded in this application according to the visual orientation shown in the accompanying drawings. Unless otherwise clearly specified and limited, terms such as "set", "installed", "connected", etc. should be understood in a broad sense. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] As Figure 1 、 Figure 4 and Figure 5 shown, a glutamic acid fermentation reactor device includes a kettle body 1. Support legs 101 are fixedly connected to the bottom of the kettle body 1. A driving motor 2 is fixedly installed at the center of the top of the kettle body 1. A gas transmission pipe 3 is fixedly connected to the top of the kettle body 1. A heating chamber 4 is fixedly provided inside the kettle body 1. A partition is fixedly provided on the heating chamber 4. A water inlet valve pipe 104 is fixedly connected to the outer wall of the lower part of the heating chamber 4. A water outlet valve pipe 105 is fixedly connected to the outer wall of the upper part of the heating chamber 4. Water meeting the temperature range of the material reaction is introduced into the heating chamber 4 through the water inlet valve pipe 104, gradually flows from the bottom to the top of the heating chamber 4, and flows out through the water outlet valve pipe 105. By setting the partition, the hot water can maintain a constantly flowing state everywhere in the heating chamber 4, avoiding the occurrence of flow dead zones and affecting the heating and heat preservation effect on the reaction chamber 5.

[0019] Inside the heating chamber 4, a reaction chamber 5 is fixedly arranged. At the bottom of the reaction chamber 5, a discharge valve pipe 102 is fixedly arranged. At the top of the reaction chamber 5, a feed inlet 103 is fixedly arranged. At the inner wall of the bottom of the reaction chamber 5, a rotary scraping rack 6 is rotatably connected. By arranging the rotary scraping rack 6, when the sealing rotary cylinder 7 rotates reversely, it drives the rotary scraping rack 6 to directly stir the side wall of the reaction chamber 5, avoiding the coking of materials due to staying close to the heating chamber 4 for a long time. At the center of the bottom of the reaction chamber 5, a fixed column 501 is fixedly connected. As Figure 6 shown, a guiding and limiting groove 502 is fixedly formed on the outer wall of the fixed column 501. At the inner wall of the top of the reaction chamber 5, a sealing rotary cylinder 7 is rotatably connected. As Figure 11 shown, a sliding port 701 is fixedly formed on the side wall of the sealing rotary cylinder 7. At the bottom of the sealing rotary cylinder 7, a gear ring 702 is fixedly connected. As Figure 10 and Figure 12 shown, a driving assembly 8 is arranged inside the sealing rotary cylinder 7. The driving assembly 8 is connected with an installation slider 9 in a matching way. By arranging the installation slider 9 and the fixed column 501, while the installation slider 9 rotates circumferentially, the installation slider 9 will also have an axial displacement under the guidance of the fixed column 501, thereby driving the stirring blade 11 to stir the materials in a larger space range, promoting the rapid and uniform mixing operation of the materials.

[0020] The installation slider 9 is slidably connected with the sliding port 701. An outer sealing flap 12 is fixedly connected to the outside of the installation slider 9. The outer sealing flap 12 is slidably connected with the outer wall of the sealing rotary cylinder 7. An adjusting sliding column 10 is arranged inside the installation slider 9. The adjusting sliding column 10 is fixedly connected with a stirring blade 11. By arranging the adjusting sliding column 10, the installation slider 9 and the driving assembly 8, when the driving assembly 8 rotates forward, the pressing end 803B pushes the adjusting sliding column 10 to the front part of the installation slider 9. At this time, the horizontal inclination angle of the stirring blade 11 is smaller. Cooperating with the high-speed rotation of the driving assembly 8, the stirring operation is completed. When the driving assembly 8 rotates reversely, the pulling end 803A pulls the adjusting sliding column 10 to the rear part of the installation slider 9. At this time, the horizontal inclination angle of the stirring blade 11 is larger. Cooperating with the low-speed rotation of the driving assembly 8, at the same time, the air vent 1003A contacts the opening 902A backward, allowing the oxygen entering the sealing rotary cylinder 7 from the gas transmission pipe 3 to be discharged from the stirring blade 11, providing sufficient oxygen for the materials.

[0021] As Figure 2 and Figure 3As shown, the partition plate includes a vertical baffle 401. A plurality of horizontal plates 402 are fixedly connected to the vertical baffle 401. A notch 402A is fixedly formed on the horizontal plate 402. The notches 402A on adjacent horizontal plates 402 are respectively arranged on both sides of the vertical baffle 401. After the heating chamber 4 is filled with warm water, as the subsequent warm water continuously flows in, it pushes the warm water in the front to continue to enter the space of the heating chamber 4 on the upper layer through the notch 402A upward. Due to the blockage of the vertical baffle 401, the warm water must completely flow through the current layer of space before it can reach the next notch 402A and continue to flow upward. Therefore, dead corners of flow can be avoided, ensuring that the reaction chamber 5 can be evenly heated or insulated.

[0022] As Figure 7 , Figure 8 and Figure 9 As shown, the rotary scraping rack 6 includes a turntable 601. The bottom of the turntable 601 is rotatably connected to the inner wall of the reaction chamber 5. The upper inner wall of the turntable 601 is rotatably connected to the outer wall of the sealed rotating cylinder 7. A plurality of chutes 601A are fixedly formed on the inner wall of the turntable 601. A scraping plate 602 is fixedly connected to the outer wall of the turntable 601. The scraping plate 602 cooperates with the inner wall of the reaction chamber 5. A driven connecting disk 603 is slidably connected to the inner wall of the turntable 601. A ratchet 603B is fixedly connected to the top of the driven connecting disk 603. The ratchet 603B cooperates with the toothed ring 702. A plurality of sliders 603A are fixedly connected to the outer wall of the driven connecting disk 603. The sliders 603A are slidably connected to the chutes 601A. A compression spring 603C is fixedly connected to the bottom of the driven connecting disk 603. The other end of the compression spring 603C is fixedly connected to the turntable 601. When the sealed rotating cylinder 7 rotates forward, the toothed ring 702 pushes the driven connecting disk 603 downward, and the scraping plate 602 stops scraping the side wall of the reaction chamber 5. When the sealed rotating cylinder 7 rotates in the reverse direction, the toothed ring 702 meshes with the ratchet 603B, and the scraping plate 602 scrapes and stirs the side wall of the reaction chamber 5, avoiding the situation that the material is in contact with the heating chamber 4 for a long time and causing coking, which affects the quality of glutamic acid.

[0023] As Figure 13 and Figure 14 As shown, the driving assembly 8 includes a transmission shaft 801. The transmission shaft 801 extends upward out of the kettle body 1. The top of the transmission shaft 801 is fixedly connected to the output shaft of the driving motor 2. A driving slide rod 802 is fixedly connected to the bottom of the transmission shaft 801. An extrusion pull ring 803 is slidably connected to the driving slide rod 802. The extrusion pull ring 803 includes a pulling end 803A and a pressing end 803B. The driving motor 2 drives the driving assembly 8 to rotate. The extrusion pull ring 803 pushes the installation slider 9 to rotate circumferentially. When the driving motor 2 drives the driving assembly 8 to rotate in different directions, the extrusion pull ring 803 can be made to cooperate with the adjusting slide column 10 at different parts, so as to adjust the horizontal inclination angle of the stirring blade 11 and control the oxygen to enter the reaction chamber 5 through the air outlet 1101B.

[0024] As Figure 15 andFigure 16 As shown, a driven rotating block 901 is rotatably connected to the rear of the installation slider 9. The driven rotating block 901 is slidably engaged with the guiding and limiting groove 502. As the installation slider 9 rotates circumferentially around the fixed column 501, the driven rotating block 901 slides in the guiding and limiting groove 502 and drives the installation slider 9 to make axial reciprocating displacements in the reverse direction, driving the stirring blade 11 to move axially and increasing the stirring range of the stirring blade 11. A rotating groove 902 is formed inside the installation slider 9. Openings 902A are formed on both sides of the rotating groove 902. The openings 902A are engaged with the extrusion pull ring 803. A front gear disc 903 is fixedly provided at the front end of the rotating groove 902, and a rear gear disc 904 is fixedly provided at the rear end of the rotating groove 902. A guiding rotating groove 902B is fixedly formed on the rear side wall of the rotating groove 902. The adjusting sliding column 10 is slidably installed in the rotating groove 902.

[0025] As Figure 17 and Figure 18 shown, the adjusting sliding column 10 includes a rear chuck 1001. The rear end of the rear chuck 1001 is engaged with the rear gear disc 904. After the two are engaged, the stirring blade 11 can be torsionally fixed to prevent its horizontal inclination angle from easily changing. The front end of the rear chuck 1001 is engaged with the pulling end 803A. A limiting convex block 1001A is fixedly connected to the side wall of the rear chuck 1001. The limiting convex block 1001A is slidably engaged with the guiding rotating groove 902B. When the pulling end 803A pulls the rear chuck 1001 backward, the adjusting sliding column 10 slides backward in the rotating groove 902. Due to the limiting action of the limiting convex block 1001A and the guiding rotating groove 902B, the adjusting sliding column 10 twists at a certain angle during the backward movement, thereby driving the stirring blade 11 to change the horizontal inclination angle to adapt to different rotational speed changes.

[0026] A connecting column 1002 is fixedly connected to the front part of the rear chuck 1001. A front chuck 1003 is fixedly connected to the front part of the connecting column 1002. The front end of the front chuck 1003 is engaged with the front gear disc 903, and the rear end of the front chuck 1003 is engaged with the pressing end 803B. A vent hole 1003A is fixedly formed on the side wall of the front chuck 1003. When the pressing end 803B presses the front chuck 1003 forward, the adjusting sliding column 10 slides forward in the rotating groove 902. Due to the limiting action of the limiting convex block 1001A and the guiding rotating groove 902B, it will also drive the stirring blade 11 to change the horizontal inclination angle. At the same time, since the adjusting sliding column 10 slides forward, the front chuck 1003 is separated from the opening 902A, thereby closing the vent hole 1003A.

[0027] As Figure 19 , Figure 20 and Figure 21As shown, the stirring blade 11 includes a fixed rod 1101, a paddle blade 1102 is fixedly connected to the outer wall of the fixed rod 1101, and a guide plate 1103 is fixedly connected to the paddle blade 1102. By setting the guide plate 1103, the paddle blade 1102 can fully contact with the material, increase the contact area between the two, and improve the stirring effect of the paddle blade 1102 on the material; a vent pipe 1101A is opened inside the fixed rod 1101, the vent pipe 1101A is connected to the vent port 1003A, and a plurality of groups of air outlets 1101B are fixedly opened on the side wall of the vent pipe 1101A, and a one-way valve 1104 is fixedly installed on the air outlet 1101B. By setting the one-way valve 1104, it can be prevented that the material drills into the vent pipe 1101A from the air outlet 1101B, causing the vent pipe 1101A to be blocked. When the vent 1003A is opened, oxygen can be discharged into the reaction chamber 5 from the outlet 1101B through the vent pipe 1101A. With the low-speed stirring of the paddle 1102, the oxygen and the material are fully contacted to ensure the smooth progress of the glutamic acid production reaction and maintain the reaction conditions.

[0028] An operating method using a glutamic acid fermentation reactor device comprises the following steps: a: Put the required materials into the reaction chamber 5 through the feed port 103, and open the water outlet valve pipe 105 and the water inlet valve pipe 104 in sequence; b: Start the drive motor 2 and rotate it in the forward direction at a high speed to stir the material radially and axially so that the material is mixed quickly; c: When the materials are uniformly mixed, the driving motor 2 is adjusted to rotate in the reverse direction at a low speed, and oxygen is introduced into the gas pipe 3. The scraper 602 directly stirs the materials close to the side wall of the reaction chamber 5. At the same time, the air outlet 1101B on the back of the stirring blade 11 introduces oxygen into the reaction chamber 5. The stirring blade 11 rotates slowly to ensure that the oxygen is fully in contact with the materials. d: Open the discharge valve pipe 102 to discharge the generated glutamic acid from the kettle body 1.

[0029] Working principle: 1. Various materials are put into the reaction chamber 5. At the beginning of the reaction, the reactor needs to quickly and fully stir the materials. Therefore, the driving motor 2 drives the driving assembly 8 to rotate forward at high speed, and the pressing end 803B of the extrusion pull ring 803 presses the adjustment slide column 10 forward, the front chuck 1003 is out of contact with the opening 902A, and the vent 1003A is closed, driving the paddle 1102 to stir the materials at high speed; 2. After the materials are fully mixed, they begin to gradually generate glutamate at a suitable temperature. If the high speed is maintained at this time, the reaction conditions will be easily destroyed, which will have a negative impact on the activity of microbial cells or enzymes. Large shear force will damage microbial cells, affect the normal metabolism and growth of cells, and affect the synthesis rate of glutamate. 3. At this time, the drive motor 2 drives the drive assembly 8 to rotate slowly in the reverse direction, squeezing the pulling end 803A of the pull ring 803 to pull the adjustment sliding column 10 backward. At the same time, the adjustment sliding column 10 twists a certain angle, driving the stirring blade 1102 to increase the horizontal inclination angle, so that at a low rotation speed, the blade 1102 can also effectively stir the material to flow and mix moderately. At the same time, the front chuck 1003 contacts the opening 902A, and the ventilation port 1003A is opened, and oxygen flows into the reaction chamber 5 from the air outlet 1101B, keeping sufficient oxygen in the reaction kettle; 4. At the same time, the reversely rotating sealing drum 7 will also drive the scraper 602 to scrape and stir the side wall of the reaction chamber 5, preventing the material here from being in close contact with the heating chamber 4 for a long time and causing coking.

[0030] In the present invention, by setting the mounting slider 9 and the fixing column 501, while the mounting slider 9 rotates circumferentially, the mounting slider 9 will also undergo axial displacement under the guidance of the fixing column 501, thereby driving the stirring blade 11 to stir the material in a larger space range, promoting the rapid and uniform completion of the mixing operation of the material; by setting the adjustment sliding column 10, the mounting slider 9 and the drive assembly 8, when the drive assembly 8 rotates forward, the pressing end 803B pushes the adjustment sliding column 10 to the front part of the mounting slider 9. At this time, the horizontal inclination angle of the stirring blade 11 is smaller, and in cooperation with the high-speed rotation of the drive assembly 8, the stirring operation is completed. When the drive assembly 8 rotates in the reverse direction, the pulling end 803A pulls the adjustment sliding column 10 to the rear part of the mounting slider 9. At this time, the horizontal inclination angle of the stirring blade 11 is larger, and in cooperation with the low-speed rotation of the drive assembly 8, at the same time, the ventilation port 1003A contacts the opening 902A backward, allowing the oxygen entering the sealing drum 7 from the gas transmission pipe 3 to be discharged from the stirring blade 11, providing sufficient oxygen for the material; by setting the partition plate, the hot water can be kept in a flowing state at all parts of the heating chamber 4, preventing the occurrence of flow dead corners and affecting the heating and heat preservation effect on the reaction chamber 5.
