Description

Technical Field

[0001] This application relates to the field of experimental instrumentation and equipment technology, and in particular to a bio-enzyme fermentation reactor. Background Technology

[0002] In bio-enzyme fermentation production, fermentation efficiency and quality directly affect product yield and performance. Traditional fermentation reactors suffer from several drawbacks. First, they have limitations in gas supply, such as the difficulty in ensuring a uniform and continuous supply of oxygen to all areas of the fermentation broth. This leads to inconsistent oxygen intake for microorganisms in different locations within the broth, with some microorganisms experiencing anaerobic metabolic activity restrictions, thus reducing the overall production efficiency of the bio-enzymes. Second, traditional equipment often fails to effectively mix the fermentation broth, resulting in uneven distribution of nutrients. This prevents microorganisms from fully absorbing nutrients, impacting the quality and yield of bio-enzymes. Furthermore, if waste gases generated during fermentation are not promptly discharged, they accumulate within the fermentation chamber, altering the pH and gas composition of the fermentation environment and inhibiting the fermentation process.

[0003] Regarding the aforementioned technologies, the inventors have discovered the following deficiencies: some existing devices on the market may lack efficient gas extraction and storage structures, making it impossible to continuously and stably provide sufficient oxygen to the fermentation broth, which affects microbial growth and metabolism, and makes it difficult to guarantee the yield and quality of biological enzymes. Many existing devices do not have a complete liquid circulation system, so nutrients, microorganisms and biological enzymes in the fermentation broth cannot be fully mixed, resulting in uneven concentration distribution, which limits the microorganisms' uptake of nutrients and thus reduces fermentation efficiency. Utility Model Content

[0020] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0021] This application discloses a bio-enzyme fermentation reactor.

[0022] Please see Figure 1 A bio-enzyme fermentation reactor includes a reaction chamber shell 1, a collection hood 2 is provided on the top of the reaction chamber shell 1, a first air pump 3 is provided on the top of the collection hood 2, and an airlift reaction assembly 4 is provided on the bottom of the reaction chamber shell 1.

[0023] Please see Figures 2 to 4The air-lift reaction assembly 4 includes an oxygen supply chamber shell 401, an annular cavity 402, a second air pump 403, an air storage tank 404, an air-lift plate 405, and an air-lift hole 406. The oxygen supply chamber shell 401 is fixedly installed at the bottom of the reaction chamber shell 1. The annular cavity 402 is opened inside the oxygen supply chamber shell 401. The annular cavity 402 is connected to the second air pump 403 through a one-way valve. The top of the second air pump 403 is connected to the air storage tank 404. The top of the oxygen supply chamber shell 401 is fixedly installed with an air-lift plate 405, and the top of the air-lift plate 405 is provided with an air-lift hole 406.

[0024] The gas lift reaction assembly 4 also includes an inlet pipe 407, a circulation pump 408, an outlet pipe 409, a positioning plate 410, and a turbulence-inducing assembly 411. One end of the inlet pipe 407 is connected to the oxygen supply chamber shell 401, and the other end of the inlet pipe 407 is connected to the circulation pump 408. One end of the outlet pipe 409 is connected to the reaction chamber shell 1, and the other end of the outlet pipe 409 is connected to the circulation pump 408. The turbulence-inducing assembly 411 is fixedly installed on the top of the oxygen supply chamber shell 401, and the positioning plate 410 is fixedly installed on the top of the turbulence-inducing assembly 411. The positioning plates 410 are all fixedly connected to one side of the gas storage tank 404.

[0025] The oxygen supply chamber shell 401, the gas storage tank 404, and the reaction chamber shell 1 together constitute the fermentation cavity, with the gas storage tank 404 located inside the reaction chamber shell 1.

[0026] The spoiler assembly 411 consists of multiple spoilers with different deflection angles, and the multiple spoilers are arranged in an alternating manner.

[0027] The inlet pipe 407, the circulation pump 408, and the outlet pipe 409 are symmetrically arranged with the oxygen supply chamber shell 401 as the center, and the spray directions of the two sets of inlet pipes 407, circulation pumps 408, and outlet pipes 409 are opposite.

[0028] The gas inside the gas storage tank 404 is drawn by the second suction pump 403 and then passes through the annular cavity 402 and the air rise hole 406 before entering the interior of the reaction chamber shell 1. The waste gas inside the reaction chamber shell 1 is collected by the first suction pump 3.

[0029] Further explanation is needed:

[0030] The airlift reaction component 4 plays a crucial role in gas supply and circulation throughout the entire bio-enzyme fermentation process. The second air pump 403 draws in external gas, which is then stored in the gas storage tank 404. When fermentation requires oxygen, the stored gas passes through the annular cavity 402 and the airlift hole 406 in sequence, and finally enters the outer shell 1 of the reaction chamber. A stable and sufficient oxygen supply is a key factor in maintaining the activity of microorganisms during fermentation. It ensures that microorganisms can carry out metabolic activities in a suitable environment, thereby efficiently promoting the production of bio-enzymes and playing an important role in improving the yield and quality of bio-enzymes.

[0031] This component forms an ingenious liquid circulation system through the inlet pipe 407, the circulation pump 408, and the outlet pipe 409. The operation of the circulation pump 408 causes the fermentation broth to be drawn from the oxygen supply chamber shell 401 through the inlet pipe 407 and then reinjected into the reaction chamber shell 1 through the outlet pipe 409. This cycle repeats continuously, allowing the nutrients, microorganisms, and enzymes in the fermentation broth to mix thoroughly, avoiding uneven concentrations in certain areas. Nutrients can be evenly distributed throughout the chamber, and microorganisms can absorb nutrients more efficiently, greatly improving fermentation efficiency and creating favorable conditions for the stable generation of enzymes.

[0032] The turbulence-inducing component 411 and the positioning plate 410 also play an indispensable role in the airlift reaction assembly 4. The turbulence-inducing component 411 is composed of multiple turbulence plates with different deflection angles and staggered arrangement. When the fermentation broth flows, the turbulence plates can change its flow direction and speed, break the possible laminar flow state, and make the fermentation broth form a complex and uniform turbulence in the cavity, avoiding the occurrence of local dead zones and further optimizing the fermentation environment. The positioning plate 410 not only fixes the gas storage tank 404, but also tightly connects the entire turbulence-inducing component 411 with other components, ensuring the structural stability of the airlift reaction assembly 4 during operation and ensuring that all components work together to provide a stable and efficient environment for bio-enzyme fermentation.

[0033] The working principle of the above embodiments is as follows:

[0034] First, the second air pump 403 is started to draw air or a specific gas from the outside and pump it into the annular cavity 402 through a one-way valve, and store it in the gas storage tank 404 to provide a sufficient gas source for the subsequent fermentation process.

[0035] Secondly, under pressure, the gas in the gas storage tank 404 passes through the annular cavity 402 in sequence, and is injected upward into the interior of the reaction chamber shell 1 through the air riser hole 406 at the top of the air riser plate 405, thereby replenishing the gas in the fermentation chamber and meeting the needs of microorganisms for oxygen and other gases during the bio-enzyme fermentation process.

[0036] Next, the circulation pump 408 starts working, drawing the fermentation broth from the outer shell of the reaction chamber 1 through the inlet pipe 407 to the outer shell of the oxygen supply chamber 401, and then transporting it back to the outer shell of the reaction chamber 1 through the outlet pipe 409, forming a circulating flow of the fermentation broth and promoting the uniform mixing of various components in the fermentation broth.

[0037] Next, during the circulation of the fermentation broth, the turbulence-disrupting component 411 comes into play. Since the turbulence-disrupting component 411 is composed of multiple turbulence plates with different deflection angles and staggered arrangement, when the fermentation broth flows through it, the turbulence plates change the flow direction and speed of the fermentation broth, avoid the occurrence of local dead zones, optimize the flow field distribution in the fermentation chamber, and further improve the uniformity and stability of fermentation.

[0038] Finally, the waste gas generated during the bio-enzyme fermentation process is extracted and collected by the first vacuum pump 3 through the collection hood 2 at the top of the reaction chamber shell 1, maintaining the stability of the fermentation environment and preventing the waste gas from having a negative impact on the fermentation process.

[0039] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
