Abstract
Description
Technical Field
[0001] The utility model relates to a microbial fermentation device. Background Art
[0002] Microbial fermentation is an important part of the preparation of microbial products. In the preparation of microbial products, it is often necessary to use the metabolic activities of microorganisms through fermentation to convert raw materials into target products. During the fermentation process, microorganisms convert organic substances in raw materials into products useful to humans, such as antibiotics, enzymes, amino acids, etc., through metabolic pathways such as decomposition and synthesis.
[0003] Existing microbial fermentation devices are usually equipped with a stirring mechanism. The stirring mechanism rotates to evenly distribute the microorganisms and raw materials. The stirring mechanism will physically contact and beat the microorganisms during the rotation process, which can easily cause damage to the microorganisms. In order to solve this problem, the prior art uses an aeration method to achieve stirring. The principle is to use bubbles for stirring. This method has a good stirring effect at the air outlet, but the stirring effect is poor during the rising of the bubbles, and the overall stirring effect is not good. To achieve a good stirring effect, the position of the exhaust port needs to be adjusted, which has high requirements. Utility Model Content

[0024] like Figure 1 As shown, a microbial fermentation device 100 of the present invention comprises: a cover body 10 and a tank body 20 .
[0025] The cover body 10 is detachably and sealedly connected to the tank body 20, and a stirring unit is provided on the cover body 10. The stirring unit is provided with a mounting portion 30, a first cavity 31, and a second cavity 33 in sequence along the depth direction of the tank body 20. The first cavity 31 and the second cavity 33 are spaced apart by a partition 32. At least a portion of the first cavity 31 and the entirety of the second cavity 33 are arranged in the tank body 20. The first cavity 31 is connected to the space of the tank body 20 through a first opening 31a, and the second cavity 33 is connected to the space of the tank body 20 through a second opening 33a. A first air blowing pipe 70 is provided in the first cavity 31, and a second air blowing pipe 60 is provided in the second cavity 33. One end of the first air blowing pipe 70 extends into the first cavity 31, and the other end extends out of the cover body 10 to be connected to an external air source. One end of the second air blowing pipe 60 extends into the second cavity 33, and the other end extends out of the cover body 10 to be connected to an external air source.
[0026] In this embodiment, the partition 32 is configured as a seal. In this configuration, the first cavity 31 and the second cavity 33 are not connected to each other and are isolated from each other. Through the air path control of the two air pipes, better liquid flow can be achieved to realize the stirring function.
[0027] In this embodiment, the mounting portion 30 is detachably sealed and connected to the cover body 10. This arrangement facilitates replacement and maintenance of the stirring unit.
[0028] In this embodiment, a first cavity 31 is formed in the mounting portion 30 . This arrangement can simplify the structure of the stirring unit.
[0029] In this embodiment, the first opening 31a is arranged on the side of the first cavity 31, and the second opening 33a is arranged on the bottom of the second cavity 33. This arrangement facilitates the formation of a longer flow path for the liquid in the tank body 2, and has a good stirring effect.
[0030] In this embodiment, a blocking sheet 33b is provided in the second cavity 33 and adjacent to the second air blowing pipe 60. With this arrangement, the two air blowing pipes alternately blow air to allow liquid to enter and exit the second cavity 33 for stirring, thereby preventing liquid from entering the second air blowing pipe 60.
[0031] In this embodiment, a water guide 33c is disposed in the second cavity 33 and on the inner wall of the cavity.
[0032] In this embodiment, the water guide member 33c is configured to be spiral. The water guide member 33c, especially the spiral water guide member, can form a vortex when the liquid enters and exits the second cavity 33, thereby further improving the stirring effect.
[0033] In this embodiment, a bracket 40a is further provided at the bottom of the tank body 20, the tank body 20 is configured as a conical tank 21, and a discharge valve 22 is provided at the bottom of the tank body. This configuration has a better discharge effect.
[0034] In this embodiment, a pulley 50 is disposed at the bottom of the bracket 40a, and this arrangement facilitates movement and transportation.
[0035] In this embodiment, a temperature sensor 40 is further provided on the cover body 10, and the temperature sensor 40 extends into the reaction liquid in the tank body. This arrangement can monitor the fermentation temperature in real time.
[0036] In this embodiment, a pH sensor 50 is further provided on the cover body 10, and the pH sensor 50 extends into the reaction liquid in the tank body. This arrangement can monitor the pH value of the fermentation in real time.
[0037] like Figure 2-3 As shown, in the use of a microbial fermentation device 100 of the utility model, the principle of achieving stirring is:
[0038] First, the mixture of the reaction liquid and the microorganism is poured into the tank body 20, and then the cover body 10 is covered. By controlling the amount of the mixed liquid poured in, the first opening 31a of the first cavity 31 is located above the mixed liquid surface A, and the second opening 33a of the second cavity 33 is placed in the mixed liquid. Figure 2 As shown, at this time, the first air blowing pipe 70 is connected to the inside and the outside through the external air source, and the second air blowing pipe 60 is blown by the external air source, and the gas enters the second cavity 33, and the mixed liquid in the second cavity 33 is discharged into the tank body 20. The gas blown in through the second air blowing pipe 60 can be discharged through the first air blowing pipe 60 to balance the air pressure in the tank body 20, so that the mixed liquid in the second cavity 33 is roughly emptied to form a cavity. In the process again, the mixed liquid flows from the second cavity 33 into the tank body 20, and then as shown in FIG. Figure 3 As shown, the second air pipe 60 stops blowing air into the second cavity, and blows air into the first air pipe 70 through an external air source, and the external gas forms air pressure on the surface A of the mixed liquid. Then, the second air pipe 60 is connected to the outside under the control of the external air source. At this time, the liquid in the tank body 20 re-enters the second cavity 33. By repeatedly switching the air intake and connection rhythm of the first air pipe 70 and the second air pipe 60, the following can be achieved. Figure 2-3The flow of the mixed liquid shown in the figure achieves a stirring effect by the reciprocating flow of the mixed liquid, and the stirring and mixing effect is better than the existing commonly used air pipe air blowing stirring.
[0039] In summary, the microbial fermentation device 100 of the utility model realizes the reciprocating flow of the mixed liquid through the cooperation of two air pipes to achieve the stirring and mixing effect. Compared with the existing commonly used air pipe air stirring, there is no need to set up multiple air ports, and the stirring and mixing effect is better.
[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified or some of the technical features may be replaced by equivalents in the specification, and these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
