Description

Technical Field

[0001] The utility model relates to the technical field of microbial cultivation, in particular to a device for extracting acetic acid bacteria in liquor Daqu. Background Art

[0002] In the process of liquor brewing, it is usually adopted to first extract high-concentration and high-purity strains (such as acetic acid bacteria, etc.), and then put the strains into the liquor brewing process to enhance the influence of the strains in the brewing process. For the extraction of strains, the corresponding strains can be selected and cultured in a specific culture medium. After the strains grow and multiply to a certain number, the strains are extracted and preserved, and the strains need to be activated before use.

[0003] During the culture process, the culture cannot be completed in one culture medium, but the culture medium needs to be replaced many times. In order to improve production efficiency, a certain amount of culture tanks are usually prepared in advance, and the calculated culture medium is put into the culture tank in advance. After the culture is completed in a culture tank, the general pipeline and the corresponding pump body are sent to the culture tank of the next level. However, in the actual culture process, the pipeline will have a certain impact on the culture. Since the interior of the pipeline is in a closed state when not in operation, the culture liquid in the pipeline will not be affected by the stirring device, that is, the culture liquid in the pipeline is always in a static state. Since this part of the culture liquid has not been fully fermented, it will have a certain adverse effect on the original fermentation liquid (such as in aerobic fermentation, the microorganisms in this part of the culture liquid are in an anaerobic fermentation process, and the strains produced by the fermentation are different). Therefore, it is necessary to optimize the details related to the transportation of the fermentation liquid during the fermentation process. Utility Model Content

[0028] Example

[0029] The following is further described in conjunction with specific embodiments. Figure 1 -Attached Figure 7 As shown, the device for extracting acetic acid bacteria in white wine Daqu of this embodiment includes a plurality of fermentation devices distributed in the vertical direction, a supporting device for supporting the fermentation devices, and a connecting device for connecting adjacent fermentation devices; the fermentation device includes a fermentation tank 11, and a feeding pipe 12 arranged on the side of the fermentation tank 11; the connecting device includes a discharge pipe 21 arranged at the lower end of the fermentation tank 11, a plugging pipe 22 sealingly and slidably arranged in the discharge pipe 21 and sealed at both ends, a first discharge port 23 opened on the side wall of the upper end of the plugging pipe 22, a second discharge port 24 opened on the side wall of the lower end of the plugging pipe 22, a third discharge port 25 opened on the side wall of the discharge pipe 21, a guide pipe 26 arranged at the third discharge port 25, and a driving device for driving the plugging pipe 22 to rise and fall; the lower end of the guide pipe 26 is connected to the fermentation tank 11 located below. Specifically, when in use, the bacterial powder is put into the fermentation tank 11 at the top, and each fermentation tank 11 is filled with a liquid culture medium. The acetic acid bacteria is initially fermented in the fermentation tank 11 at the top. After fermentation for a certain period of time, it is discharged into the fermentation tank 11 below through a connecting device to continue fermentation. After fermentation for a certain period of time, it is discharged downward, and thus, a high concentration of acetic acid bacteria liquid is finally discharged from the fermentation device at the bottom, and can be stored after detection. In this process, the connecting device can avoid the presence of fermentation liquid in the pipeline of the connecting device during the fermentation process (this part of the fermentation liquid cannot be fully stirred, so that it lacks dissolved oxygen, and its fermentation products will have an adverse effect on the original fermentation liquid), which is mainly driven by the driving device to drive the blocking pipe 22 to completely block the discharge pipe 21, that is, the upper end of the blocking pipe 22 can be directly at the same height as the upper end of the discharge pipe 21 (such as the attached Figure 3 As shown in the figure, there will be no fermentation liquid in the connection device, which can effectively ensure the quality of the fermentation liquid. When discharge is required, the driving device drives the plugging pipe 22 to move upward so that the first discharge port 23 of the plugging pipe 22 is located above the discharge pipe 21 (as shown in the figure). Figure 4As shown in FIG. 1 , the fermented liquid in the fermentation tank 11 can enter the plugging pipe 22 through the first discharge port 23, and enter the third discharge port 25 of the discharge pipe 21 from the second discharge port 24, and finally be discharged into the fermentation tank 11 below through the guide pipe 26. In addition, by using a multi-stage fermentation tank 11 structure, each fermentation tank 11 can prepare the culture medium in advance, which can realize automatic and uninterrupted fermentation and improve production efficiency.

[0030] The lower end of the discharge pipe 21 in this embodiment is a sealed end; the driving device includes an air compressor and an air pressure pipe connected to the air compressor; the air pressure pipe is connected to the side wall of the lower end of the discharge pipe 21. Specifically, the air compressor pumps gas into the lower end of the discharge pipe 21 through the air pressure pipe, thereby lifting the blocking pipe 22, so that the first discharge port 23 of the blocking pipe 22 is higher than the discharge pipe 21, and then the discharge operation starts. After the discharge is completed, the air is released, and the blocking pipe 22 returns to the discharge pipe 21 under its own gravity.

[0031] In this embodiment, a baffle is provided at the upper end of the blocking pipe 22, and the diameter of the baffle is larger than the inner diameter of the discharge pipe 21. Specifically, the baffle can better seal the discharge pipe 21 to prevent the fermentation liquid from leaking.

[0032] The fermentation device in this embodiment also includes a stirring device arranged in the fermentation tank 11; the stirring device includes a stirring motor 13 arranged above the fermentation tank 11, a stirring shaft 14 vertically arranged in the fermentation tank 11, and a stirring blade 16 connected to the stirring shaft 14; the stirring shaft 14 is connected to the output shaft of the stirring motor 13. The stirring device also includes a pressing block 17 arranged at the lower end of the stirring shaft 14, and a telescopic joint 15 for connecting the motor output shaft and the stirring shaft 14; the pressing block 17 is pressed on the upper end wall of the plugging pipe 22. Specifically, since acetic acid bacteria are aerobic bacteria, stirring the fermentation liquid by the stirring device can effectively increase the dissolved oxygen of the fermentation liquid and improve the colony reproduction rate. Among them, the pressing block 17 pressed on the plugging pipe 22 can well assist in sealing the discharge pipe 21. When the plugging pipe 22 rises, due to the limited telescopic range of the telescopic joint 15, the height of the plugging pipe 22 can be limited by the stirring shaft 14 and the telescopic joint 15 to prevent it from escaping from the discharge pipe 21.

[0033] In this embodiment, a powder distribution device connected to the fermentation tank 11 at the uppermost end is also included; the powder distribution device includes a powder inlet 31 provided on the upper end wall of the fermentation tank 11, a powder distribution tube 32 provided at the powder inlet 31, a clamping ring 33 provided on the inner wall of the powder distribution tube 32, a powder distribution box 34 provided on the upper side of the clamping ring 33, a powder distribution hole 35 provided on the bottom wall of the powder distribution box 34, a cover 36 provided on the upper end of the powder distribution box 34, and a vibration motor 37 connected to the cover 36. Specifically, the powder distribution device can evenly sprinkle the bacterial powder in the culture medium to prevent it from agglomerating. The powder distribution box 34 can be taken out, and then the bacterial powder can be poured into the powder distribution box 34, the cover 36 can be covered, and then the powder distribution box 34 can be placed in the powder distribution tube 32, and the powder distribution box 34 can vibrate under the action of the vibration motor 37, and the bacterial powder in the powder distribution box 34 can be slowly sprinkled in the fermentation tank 11, wherein the micro vibration motor 37 can be used to make the powder distribution box 34 vibrate slightly.

[0034] The fermentation device in this embodiment further includes a pH detection device 18 and a dissolved oxygen detection device 19 which are arranged on the side wall of the fermentation tank 11 .

[0035] The supporting device in this embodiment includes a collar 41 sleeved on the outer wall of the fermentation tank 11 , and a supporting rod 42 connected to the collar 41 .

[0036] In summary, the extraction device of acetic acid bacteria in the liquor Daqu of the present embodiment, when in use, the bacterial powder is put into the fermentation tank 11 at the top, each fermentation tank 11 is equipped with a liquid culture medium, and the acetic acid bacteria is initially fermented in the fermentation tank 11 at the top, and after fermentation for a certain period of time, it is discharged into the fermentation tank 11 below through the connecting device to continue fermentation, and then discharged downward after fermentation for a certain period of time, so that the high concentration of acetic acid bacteria liquid is finally discharged from the fermentation device at the bottom, and can be stored after detection. In this process, the connecting device can avoid the presence of fermentation liquid in the pipeline of the connecting device during the fermentation process (this part of the fermentation liquid cannot be fully stirred, so that it is insufficient in dissolved oxygen, and its fermentation product will have an adverse effect on the original fermentation liquid), which is mainly driven by the driving device to drive the blocking pipe 22 to completely block the discharge pipe 21, that is, the upper end of the blocking pipe 22 can be directly at the same height as the upper end of the discharge pipe 21, so that there will be no fermentation liquid in the connecting device, and the quality of the fermentation liquid can be effectively guaranteed. In addition, by using a multi-stage fermentation tank 11 structure, each fermentation tank 11 can prepare culture medium in advance, which can realize automatic and uninterrupted fermentation and improve production efficiency.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
