Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bacterial fermentation, in particular to an anaerobic fermentation device for preparing filtrate of galactose yeast-like bacteria fermentation product. Background Art
[0002] The anaerobic fermentation device required for preparing the filtrate of the fermentation product of galactosaccharomyces cerevisiae has the main function of providing a tightly controlled environment to promote the growth and metabolism of galactosaccharomyces cerevisiae, thereby efficiently producing specific biochemical products such as enzymes, organic acids, etc.
[0003] During the fermentation process, the most important thing is to maintain the anaerobic state. To maintain the anaerobic state, the interior of the main body needs to be sealed. However, after traditional sealing, the materials inside the main body react to produce excess gas, which changes the composition of the gas inside the fermentation system, thereby affecting the growth and metabolism of microorganisms and reducing the efficiency and yield of the reaction.
[0004] Secondly, other gases generated during the fermentation process (such as toxic or harmful gases such as hydrogen sulfide) are mixed into the inert gas. At this time, these harmful components need to be filtered out, because the exhausted gas will be recycled or reused. In the inert gas replacement system, ensuring the purity of the gas can reduce the cost and complexity of subsequent processing, and can also protect the normal operation of the recovery system.

[0028] Embodiment 1:

[0030] In this embodiment, the gas replacement mechanism includes a gas generator 2, an air intake pipe 3, a pressure regulating valve 4, a flow meter 5 and an exhaust pipe 6. When in use, the gas generator 2 operates to generate inert gas. After the inert gas enters the gas pump 20 and is pressurized by the gas pump 20, the inert gas passes through the air intake pipe 3 and passes through the pressure regulating valve 4 and the flow meter 5 in turn. After detecting that the flow rate is normal and adjusting the pressure, the inert gas enters the main body 1 through the air intake port 17. After entering the main body 1, the gas generated during the reaction inside the main body 1 and the oxygen entering during the feeding are entrained and brought into the exhaust port 18 together. Then, the excess gas passes through the filter 7 installed on the exhaust pipe 6, and the impurities inside the inert gas are filtered out and then enter the gas generator 2 to enter the next cycle. In the above, the role of the gas pump 20 is to act as a power mechanism in the inert gas replacement mechanism, and the pressure regulating valve 4 is to prevent the inert gas pressure from being too high, and ensure that the gas enters the system at an appropriate rate and pressure.
[0031] In this embodiment, the sealing and filtering mechanism includes a filter 7, a connecting sleeve 8, a sealing ring 9 and an insertion tube 10. When in use, when the inert gas entrains impurities inside the main body 1 and enters the exhaust pipe 6, the filter 7 filters the inert gas to absorb the internal impurities. When in use, the insertion tube 10 is inserted into the exhaust pipe 6, and the sealing ring 9 therein fits tightly with the inside of the exhaust pipe 6. After the insertion tubes 10 at both ends of the filter 7 are inserted a certain distance, the sliding ring 19 is pushed. At this time, the sliding ring 19 will contact the exhaust pipe 6 with the connecting sleeve 8. At this time, the connecting sleeve 8 is rotated, and the connecting sleeve 8 is threadedly engaged with the exhaust pipe 6. In this process, the sliding ring 19 tightly fixes the sealing ring 9 at one end of the insertion tube 10 to achieve sealing.
[0032] In this embodiment, the stirring mechanism includes a stirring motor 11, a stirring shaft 12, a discharge pipe 13 and a check valve 14. During use, after the material enters the feed pipe 21, the check valve 14 on the discharge pipe 13 is closed, and the stirring motor 11 is driven to drive the stirring shaft 12, and the branch 15 on the stirring shaft 12 also rotates accordingly. The stirring plate 16 installed on the branch 15 also contacts the material under the drive of the stirring shaft 12, thereby rotating to fully stir the material. During this process, one end of the stirring shaft 12 is fixedly connected to the stirring motor 11, and the other end thereof rotates inside the fixed base 22.
[0033] Embodiment 2:
[0034] In summary, when in use, after the material enters the feed pipe 21, the check valve 14 on the discharge pipe 13 is closed, and the stirring motor 11 is driven to drive the stirring shaft 12, and the branch 15 on the stirring shaft 12 also rotates accordingly, and the stirring plate 16 installed on the branch 15 is also driven by the stirring shaft 12 to contact the material, thereby rotating to fully stir the material. In this process, one end of the stirring shaft 12 is fixedly connected to the stirring motor 11, and the other end thereof rotates inside the fixed base 22, and as the stirring plate 16 rotates, the stirring motor 11 rotates. The content of other gases such as carbon dioxide generated by the fermentation reaction increases, and the gas generator 2 operates to generate inert gas. After the inert gas enters the gas pump 20 and is pressurized by the gas pump 20, the inert gas passes through the intake pipe 3 and sequentially passes through the pressure regulating valve 4 and the flow meter 5. After detecting that the flow rate is normal and adjusting the pressure, the inert gas enters the main body 1 through the air inlet 17. After entering the main body 1, the gas generated by the reaction inside the main body 1 and the oxygen entering during the feeding are entrained and brought into the exhaust port 18, and then Then, the excess gas passes through the filter 7 installed on the exhaust pipe 6. When the inert gas entrains the impurities inside the main body 1 and enters the exhaust pipe 6, the filter 7 filters the inert gas and absorbs the internal impurities. When replacing and installing the filter 7, the insertion tube 10 is inserted into the exhaust pipe 6, and the sealing ring 9 therein fits tightly with the inside of the exhaust pipe 6. After the insertion tubes 10 at both ends of the filter 7 are inserted for a certain distance, the sliding ring 19 is pushed. At this time, the sliding ring 19 will bring the connecting sleeve 8 into contact with the exhaust pipe 6. At this time, the connecting sleeve 8 is rotated, and the connecting sleeve 8 is threadedly engaged with the exhaust pipe 6. In this process, the sliding ring 19 tightly fixes the sealing ring 9 at one end of the insertion tube 10 to achieve sealing. After filtering the impurities inside the inert gas, the inert gas enters the gas generator 2 and enters the next cycle. In the above, the role of the gas pump 20 is to act as a power mechanism in the inert gas replacement mechanism, and the pressure regulating valve 4 prevents the inert gas pressure from being too high, ensures that the gas enters the main body 1 at an appropriate rate and pressure, and completes the gas replacement inside the main body 1. In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described one by one here. In the above, all fixed connections are preferably welded.
