Technical Field

[0001] This invention relates to the field of acetic acid fermentation technology, and in particular to a device for improving the efficiency of acetic acid fermentation. Background Technology

[0002] Acetic acid fermentation is a type of oxidative fermentation. The main microorganisms in acetic acid fermentation are acetic acid bacteria. Acetic acid fermentation refers to the process by which ethanol is oxidized into acetic acid under the action of acetic acid bacteria. Acetic acid fermentation is usually carried out in a fermentation tank. A fermentation tank is an industrial device used for microbial fermentation. Its main body is generally a cylindrical column made of stainless steel plate. Fermentation tanks have a wide range of uses, playing an important role not only in the food, pharmaceutical, and brewing industries, but also in the fields of biofuel and bioproduct production.

[0003] The existing technology has the following shortcomings;

[0004] Traditional fermenters mostly use coil heating components. These components are usually embedded inside or outside the tank. When it is necessary to disassemble or repair the heating components, workers must first remove some tank components or move a large amount of equipment before they can take out the heating components. The operation process is cumbersome and time-consuming, which seriously affects the continuity of production. Summary of the Invention

[0029] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0030] Please see Figure 1-9 The present invention provides a technical solution:

[0031] Example 1

[0032] A device for improving the efficiency of acetic acid fermentation includes: a fermentation tank 100, a tank cover 200 on the top of the fermentation tank 100, a stirring assembly 300 fixedly mounted on the top of the tank cover 200, a feed inlet 210 fixedly mounted on the top of the tank cover 200, three sets of connecting pipes 220 fixedly mounted around the stirring assembly 300 on the tank cover 200, an electromagnetic heating assembly 400 mounted inside the connecting pipes 220, and a discharge outlet 130 fixedly mounted at the center of the bottom of the fermentation tank 100.

[0033] An installation ring 500 is set on the outer surface of the fermenter 100. The installation ring 500 is positioned above the fermenter 100. A connecting block 510 is fixedly installed on the installation ring 500 at the position corresponding to the connecting pipe 220. A rotating rod 520 is fixedly installed at the other end of the connecting block 510. A connecting frame 530 is rotatably installed on the rotating rod 520. A support ring 540 is fixedly installed on the connecting frame 530.

[0034] When fermenting acetic acid, the top of the tank lid 200 is first fixed to the top of the fermentation tank 100, and the free end of the support ring 540 is rotated so that it is above the connecting pipe 220. Then, the electromagnetic heating component 400 is placed inside the fermentation tank 100 through the connecting pipe 220. At this time, the electromagnetic heating component 400 is above the support ring 540 and supports it. Then, the raw materials required for acetic acid fermentation are added to the fermentation tank 100 through the feed port 210. At this time, the electromagnetic heating component 400 is energized to generate microwave resonant energy to heat the raw materials inside the fermentation tank 100 and provide a suitable temperature for the fermentation process. Then, the stirring component 300 is started to stir the raw materials inside the fermentation tank 100 to avoid temperature stratification. After fermentation is completed, the fermented raw materials are discharged through the discharge port 130 at the bottom of the fermentation tank 100.

[0035] Example 2

[0036] Please see Figure 1 , Figure 2 In order to further ensure the stability of the installation of the electromagnetic heating assembly 400 based on Embodiment 1, a preferred embodiment of the fixing ring 120 is given.

[0037] A fixing ring 120 is fixedly installed below the mounting ring 500 in the fermenter 100. The mounting ring 500 is sleeved on the outer surface of the fermenter 100 and is located above the fixing ring 120. The support ring 540 is located above the connecting pipe 220.

[0038] By setting the fixing ring 120, when installing the electromagnetic heating component 400, the fixing ring 120 plays a limiting and supporting role, preventing the installation ring 500 from sliding down, ensuring that the support ring 540 is always above the connecting pipe 220, and maintaining the stability of the electromagnetic heating component 400.

[0039] For further refinement of connector 530, please refer to Figure 2 , Figure 3 , Figure 7 , Figure 8 A fixing block 550 is fixedly installed on the rotating rod 520. A movable groove 560 is opened at the hinge end of the connecting frame 530 corresponding to the position of the fixing block 550. One end of the movable groove 560 is in contact with the fixing block 550, and a gap is left between the other end of the movable groove 560 and the fixing block 550.

[0040] By setting and using the fixed block 550 and the movable groove 560 together, the connecting frame 530 can swing flexibly within a certain angle range, thereby adjusting the position of the support ring 540 so that it can be moved to the outside of the fermentation tank 100 and placed on the side of the fermentation tank 100 after the electromagnetic heating component 400 is disassembled.

[0041] For further details on connecting block 510, please refer to [link / reference]. Figure 1 , Figure 7 The connecting block 510 is arc-shaped and matches the rounded corners of the top of the fermenter 100.

[0042] By using the arc-shaped design of the connecting block 510, when supporting the electromagnetic heating component 400, the connecting block 510 can fit closely to the outer wall of the fermentation tank 100, reducing stress concentration, improving structural strength, enhancing connection stability, and extending service life.

[0043] Example 3

[0044] Please see Figure 5 To further ensure temperature stratification during fermentation, based on Example 1, a preferred embodiment of the stirring assembly 300 is provided.

[0045] The stirring assembly 300 includes a motor 310 fixedly mounted on the tank cover 200. The output end of the motor 310 extends into the interior of the fermentation tank 100 and is fixedly mounted on a rotating shaft 320. A stirring blade 330 is fixedly mounted on the rotating shaft 320.

[0046] By setting the stirring component 300, the motor 310 is started. The output end of the motor 310 drives the rotating shaft 320 to rotate. The rotating shaft 320 then drives the stirring blade 330 to rotate inside the fermentation tank 100. During the rotation of the stirring blade 330, the raw materials inside the fermentation tank 100 are stirred, so that the raw materials are fully mixed. At the same time, it breaks up the possible temperature stratification, allowing the heat generated by the electromagnetic heating component 400 to be transferred more evenly to all parts of the raw materials, improving the uniformity of the raw material mixing, promoting the metabolic activity of acetic acid bacteria, avoiding temperature stratification, and improving fermentation efficiency.

[0047] To further refine the installation of the can lid 200, please refer to [link / reference needed]. Figure 1 ,to Figure 4 The top of the connecting pipe 220 is fixedly provided with multiple sets of first limiting blocks 230. The first limiting blocks 230 are adapted to the outer surface of the support ring 540. The top of the fermentation tank 100 is provided with an opening 600 adapted to the tank cover 200, and a limiting ring 610 is fixedly provided. A limiting groove 620 is provided on the inner side of the opening 600. Multiple sets of bolts 630 are threaded between the limiting ring 610 and the tank cover 200.

[0048] With the setting of the limiting ring 610, when installing the tank cover 200, the tank cover 200 is aligned with the opening 600 at the top of the fermentation tank 100, so that its edge is embedded in the inside of the limiting groove 620. The limiting groove 620 can play a preliminary positioning and limiting role for the tank cover 200, ensuring the accuracy of the installation position of the tank cover 200. Subsequently, multiple sets of bolts 630 are screwed between the limiting ring 610 and the tank cover 200 to firmly fix the tank cover 200 on the fermentation tank 100.

[0049] To further observe the fermentation process inside fermenter 100, please refer to [link / reference needed]. Figure 1 Each fermenter 100 has an observation window 110 between every two sets of connecting blocks 510, and the observation window 110 is located above the fermenter 100.

[0050] With the setting of the observation window 110, which is made of transparent material, the staff can directly observe the fermentation status of the raw materials inside the fermentation tank 100 during the acetic acid fermentation process, such as the color of the raw materials, the liquid level, and whether there is abnormal foam, without having to open the tank lid 200 to grasp the fermentation process.

[0051] Example 4

[0052] Please see Figure 5 , Figure 6 In order to further improve the stability of heating the raw materials based on Embodiment 1, a preferred embodiment of the electromagnetic heating component 400 is given.

[0053] The electromagnetic heating assembly 400 includes a mounting post 410 and a cover plate 420. The mounting post 410 has a mounting cavity 430 inside, and an electromagnetic coil 440 is fixedly installed inside the mounting cavity 430.

[0054] When the electromagnetic coil 440 is energized, it generates an alternating magnetic field, and the inner coil generates a magnetic field accordingly. This magnetic field acts on the mounting column 410, which is mainly made of metal, thereby generating eddy currents. This generates a large amount of heat inside the fermentation tank 100. The generated heat is conducted to the fermentation raw materials through the outer wall of the mounting column 410. Compared with traditional coil heating, electromagnetic heating has low thermal inertia and fast temperature control response. It can quickly adjust the heating temperature to adapt to the temperature requirements of different stages of acetic acid fermentation and reduce the problem of temperature control lag.

[0055] For further improvements to the stability of the electromagnetic heating assembly 400 installation, please refer to [link / reference]. Figures 1 to 4 as well as Figure 6 , Figure 9 The cover plate 420 is fixedly provided with multiple sets of second limit blocks 450 on the side corresponding to the first limit block 230. The second limit blocks 450 are adapted to the outer surface of the support ring 540, and the top of the cover plate 420 is fixedly provided with a handle 460.

[0056] With the setting of the second limiting block 450 and the first limiting block 230, when the electromagnetic heating component 400 is installed, the second limiting block 450 is locked on the upper surface of the support ring 540, and the lower surface of the support ring 540 is locked inside the first limiting block 230, so as to prevent the electromagnetic heating component 400 from shifting during the operation of the equipment. At the same time, the operator can take out or put in the electromagnetic heating component 400 through the handle 460.

[0057] The above embodiments are merely illustrative of the technical solutions of the present invention and are not intended to limit it. Anyone skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
