Description

Technical Field

[0001] The invention relates to the field of bacterial fermentation and culture, and in particular to an adaptive bacterial fermentation and culture device. Background Art

[0002] As is known to all, bacteria refer to one of the main groups of organisms, belonging to the bacterial domain. The shapes of bacteria are quite diverse, mainly spherical, rod-shaped, and spiral-shaped. Bacteria also have a great impact on human activities. On the one hand, bacteria are pathogens of many diseases, and can spread diseases between normal human bodies in various ways, such as contact, digestive tract, respiratory tract, insect bites, etc. They are highly contagious and pose a great threat to society. On the other hand, humans also often use bacteria. For example, the production of cheese, yogurt, and fermented rice, the manufacture of some antibiotics, and the treatment of wastewater are all related to bacteria. In the field of biotechnology, bacteria are also widely used, and the bacterial fermentation culture device is a device used to culture bacteria;

[0003] For example, the authorization announcement number is CN 116606713B, the authorization announcement date is 2024.03.15, and the name is a bacterial colony culture device, which includes a culture tube, an air pump, a hollow seat, a hollow cone, a rubber sealing plug, a recovery tube and a vertical tube; when culturing the bacterial colony, the bacterial colony is inoculated into the culture tube filled with culture solution, and the culture tube is inserted into the circular groove of the disc so that the hollow cone passes through the rubber sealing plug; after the culture tube is placed, the incubator is closed to culture the bacterial colony, and the metabolites produced by the bacterial colony during the reproduction and growth process are precipitated to the bottom of the culture tube...;

[0004] Most of the bacterial fermentation culture devices in the prior art do not have a sediment treatment structure, and are often cleaned once the bacterial culture is completed. A few culture devices have some sediment removal structures, which are basically the same as the above-mentioned application. A tube-like structure is provided in the culture device to regularly suck the bottom of the culture device to achieve sediment cleaning. However, this cleaning structure is often very destructive to the environment inside the culture device when cleaning the sediment, affecting the bacterial culture, and easily sucking out the bacterial flora and culture fluid, which also affects the bacterial culture. In addition, the internal oxygen supply structure of the existing culture device is basically directly connected to an oxygen supply pipeline for oxygen supply, which can easily lead to high oxygen content in some places inside the culture device and low oxygen content in some places, thereby causing uneven growth of the bacterial flora, which is not conducive to large-scale bacterial culture and fermentation.

DETAILED DESCRIPTION

[0040] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, and use. It should be understood that in all of these figures, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically represent the concepts and principles of the embodiments of the present disclosure, and do not necessarily show the specific dimensions and proportions of the various embodiments of the present disclosure. Specific parts in specific drawings may be exaggerated to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0041] Reference Figure 1-13:The present embodiment provides a technical solution: an adaptive bacterial fermentation and culture device, comprising a device body 1 and a control device 2 installed outside the device body 1. Specifically, a turntable 6 driven by a motor and a gear set (not shown in the figure) is installed at the lower part of the device body 1, and a support assembly 4 is fixedly installed above the turntable 6. A door 3 is installed on the front surface of the device body 1. A plurality of fermentation and culture components 5 are detachably installed inside the device body 1 through the support assembly 4, and a precipitation container 7, a culture liquid storage container 8 and an oxygen storage container 9 are also fixedly installed through the support assembly 4. The precipitation container 7, the culture liquid storage container 8 and the oxygen storage container 9 are connected to the fermentation and culture component 5 through pipelines. The control device 2 is used to control the culture liquid storage container 8 and the oxygen storage container 9 according to the fermentation growth requirements of the bacteria in the fermentation and culture component 5. The device 9 replenishes the culture fluid and oxygen into the fermentation culture component 5. Many bacteria need to consume the culture fluid and the oxygen in the culture fluid during the fermentation and growth process. In this embodiment, by directly connecting the fermentation culture component 5 with the oxygen storage container 9, the oxygen storage container 9 can continuously inject oxygen into the fermentation culture component 5 to provide the bacteria with the oxygen they need, so that the growth environment of the bacteria is more in line with their needs, which is conducive to the fermentation and cultivation of bacteria. Furthermore, the fermentation culture component 5 is connected with a drain pipe, one end of which is inserted into the upper part of the fermentation culture component 5, and the other end is connected to a negative pressure liquid suction container equipped with a solenoid valve, which is used to regularly discharge the upper clear liquid of the culture fluid. Furthermore, the fermentation culture component 5 is also provided with a pressure relief exhaust pipe, which is used to regularly discharge the gas in the fermentation culture component 5 to achieve decompression inside the fermentation culture component 5.

[0042] The present embodiment provides an adaptive bacterial fermentation and cultivation device. Specifically, the fermentation and cultivation component 5 includes a fermentation tank 51 and a cover body 50 with a window detachably mounted on the top of the fermentation tank 51, so that the internal environmental state of the fermentation tank 51 can be conveniently observed. An oxygen distribution pipeline 515 is installed at the lower part of the fermentation tank 51, and an oxygen supply pipe 511 is connected to the upper part of the oxygen distribution pipeline 515. The oxygen supply pipe 511 is connected to the oxygen storage container 9 through a hose. Oxygen can be continuously injected into the fermentation tank 51 through the oxygen supply pipe 511 to provide an oxygen-rich environment for the growth of bacteria, and then the oxygen supply pipe 515 is connected to the oxygen storage container 9 through the oxygen supply pipe 511. 515 is evenly distributed in the fermentation tank 51, so that the oxygen content in the bacterial growth environment in the fermentation tank 51 is uniform. A liquid infusion tube 512 is fixedly installed on one side of the oxygen supply tube 511 through a fixed chuck 514. The liquid infusion tube 512 is connected to the culture solution storage container 8 through a hose. Supplementary culture solution can be regularly injected into the fermentation tank 51 through the liquid infusion tube 512. The connection structure of the hose can improve the mobility of the fermentation culture component 5. Furthermore, pumps (not shown in the figure) are provided in the culture solution storage container 8 and the oxygen storage container 9 to provide power for liquid supply and oxygen supply.

[0043] The present embodiment provides an adaptive bacterial fermentation and cultivation device. Specifically, the oxygen distribution pipeline 515 is composed of a plurality of main ring tubes 5150 in a circular ring structure. The plurality of main ring tubes 5150 are connected to each other. A plurality of inner control tubes 5151 are movably fitted in each main ring tube 5150. A plurality of air holes are provided on the surfaces of the main ring tubes 5150 and the inner control tubes 5151. A control mechanism for controlling the movement of the inner control tubes 5151 is also installed on the main ring tubes 5150. Under the control of the control mechanism, the effective ventilation diameters of the air holes on the main ring tubes 5150 and the inner control tubes 5151 change. The structural setting of the oxygen distribution pipeline 515 makes the oxygen supply position inside the fermentation tank 51 uniform, so that the dissolved oxygen can be more comprehensive during the oxygen supply process, which is beneficial to the cultivation of bacteria. In the present embodiment, a plurality of internal control tubes 5151 are movably assembled in the main ring tube 5150, and the internal control tubes 5151 can change the effective ventilation diameter of the air hole through the control of the control mechanism, thereby achieving the effect of "changing the diameter on demand", that is, changing the oxygen supply diameter according to the actual regional oxygen supply needs, thereby changing the oxygen supply speed within a period of time, making the oxygen supply more accurate, and making the bacterial culture environment more suitable.

[0044] The present embodiment provides an adaptive bacterial fermentation and cultivation device. Specifically, a notch 5155 is provided on the inner side of the main ring tube 5150. The control mechanism includes an arc-shaped rack 5152 and a support plate 5154. The arc-shaped rack 5152 is located in the notch 5155 and is fixedly connected to the inner control tube 5151. The support plate 5154 is fixed to the outer wall of the main ring tube 5150. A servo motor 5153 is installed above the support plate 5154. The output group of the servo motor 5153 is equipped with a motor adapted to the arc-shaped rack 5152. The driving gear 5156 rotates when the servo motor 5153 is running. Since the driving gear 5156 is meshed with the arc-shaped rack 5152, the inner control tube 5151 is driven to move in the main ring tube 5150 through the arc-shaped rack 5152, so that the air holes of the inner control tube 5151 on the main ring tube 5150 are converted from complete overlap to misalignment and non-overlapping, or from misalignment and non-overlapping to complete overlap. In this process, the effective ventilation diameter of the air holes changes, thereby realizing a change in the oxygen supply speed.

[0045] The present embodiment provides an adaptive bacterial fermentation and cultivation device. Specifically, a sedimentation storage tube 513 is installed at the bottom of the fermentation tank 51. The sedimentation storage tube 513 adopts an S-shaped structure. Both ends of the sedimentation storage tube 513 are provided with electromagnetic control valves. One end of the sedimentation storage tube 513 connected to the fermentation tank 51 is provided with a venting valve tube 5130 below the electromagnetic control valve. The end of the sedimentation storage tube 513 is connected to the sedimentation container 7 through a hose. Furthermore, the bottom of the fermentation tank 51 adopts a funnel-shaped structure. In the mass fermentation and cultivation production process of the bacterial flora, a large amount of metabolites will be produced and precipitated to the bottom of the fermentation tank 51 (the precipitates are usually metal elements, Protein and other culture medium components are precipitated), too much precipitate will damage the normal culture of the bacterial flora. The setting of the precipitation storage tube 513 allows the precipitate to gradually gather in the sedimentation storage tube 513 after precipitation, while the bacteria will exist in the fermentation tank 51 due to their own fermentation and growth needs, thus achieving the separation of the precipitate. After the set time, the internal space of the sedimentation storage tube 513 can be isolated by controlling the electromagnetic control valve, and then the valve between the vent valve tube 5130 and the sedimentation container 7 is opened, so that the precipitate in the sedimentation storage tube 513 can be sucked into the sedimentation container 7 for storage, thereby achieving the automatic cleaning effect of the precipitate, which is beneficial to the long-term culture of bacteria.

[0046] The present embodiment provides an adaptive bacterial fermentation and culture device. Specifically, a temperature sensor 517 and an oxygen concentration sensor 518 are mounted at the lower part of the fermentation tank 51 through a fixed clamp 516. An electric heating ring 519 is embedded and installed at the lower part of the inner wall of the fermentation tank 51. The temperature sensor 517 can sense the temperature of the culture solution in real time. When the temperature is lower than the set threshold value that is conducive to bacterial growth, the electric heating ring 519 will generate heat to ensure that the temperature of the culture solution is suitable.

[0047] This embodiment provides an adaptive bacterial fermentation culture device. Specifically, the output end of the oxygen concentration sensor 518 is electrically connected to the input end of the control device 2, and the output end of the control device 2 is electrically connected to the input end of the servo motor 5153. The number of oxygen concentration sensors 518 is consistent with the number of internal control tubes 5151, and both are set to n, where n is greater than or equal to 4, and n is a positive integer. The area volume of each oxygen concentration sensor 518 to obtain oxygen concentration is similar. The control method of the control device 2 is as follows:

[0048] According to the number distribution of the oxygen concentration sensors 518, the internal space of the fermentation tank 51 is divided into a number of regions of similar volume, and each region is marked;

[0049] The oxygen concentration in each area is sensed by the oxygen concentration sensor 518, and the oxygen concentration in each area is obtained, which is set as P, to determine whether the amount of oxygen supply needs to be changed;

[0050] The method to determine whether the amount of oxygen supply needs to be changed is as follows:

[0051] The oxygen concentration suitable interval is set to [P1, P2]. When the value of P is not between [P1, P2], it is determined that the amount of oxygen supply needs to be changed.

[0052] When it is determined that the amount of oxygen supply needs to be changed, the servo motor 5153 in the area is controlled to operate so that the effective ventilation diameter of the air holes on the main ring tube 5150 and the inner control tube 5151 in the area is changed. The method of controlling the servo motor 5153 is as follows:

[0053] If P≤P1, it is determined that the oxygen supply speed needs to be increased in the current area, and the control device 2 controls the servo motor 5153 in the current area to operate, so that the effective ventilation diameter of the air holes in the current area increases, and the oxygen supply speed increases until P=1 / 2(P1+P2);

[0054] If P≥P2, it is determined that the oxygen supply speed needs to be reduced in the current area, and the control device 2 controls the servo motor 5153 in the current area to operate, so that the effective ventilation diameter of the air holes in the current area is reduced, and the oxygen supply speed is reduced until P=1 / 2(P1+P2).

[0055] The present embodiment provides an adaptive bacterial fermentation culture device. Specifically, the support component 4 includes an annular assembly part 41 and a stand 40, wherein the annular assembly part 41 is provided with a plurality of annular assembly parts 41, and the plurality of annular assembly parts 41 are interconnected. The stand 40 is provided below the annular assembly part 41 and is used to support the annular assembly part 41. The inner side of the annular assembly part 41 is connected to a vibration ring frame 410 through an elastic connecting part 411. The elastic connecting part 411 adopts a spring. There are a plurality of elastic connecting parts 411, and the plurality of elastic connecting parts 411 are distributed in an annular array. The fermentation tank 51 is detachably mounted on the inner side of the vibration ring frame 410. The annular assembly part A vibration motor 412 for controlling the vibration of the vibration ring frame 410 is fixedly installed on the outer side of 41. Such a structural arrangement makes it easy to disassemble and assemble the fermenter 51 as a whole, and facilitates the handling of the fermenter 51. In actual applications, the vibration of the vibration ring frame 410 can be controlled by the vibration motor 412, so that the fermenter 51 can vibrate during the fermentation process, realizing the "shaking table function", which is beneficial to the fermentation and cultivation of bacteria. In addition, such vibration can also make the sediment in the fermenter 51 quickly gather to the sediment storage tube 513 at the bottom of the fermenter 51, which can greatly reduce the influence of the sediment on the bacterial fermentation and cultivation, and further optimize the environment for bacterial fermentation and cultivation.

[0056] Furthermore, a fixed plate 42 is provided in the middle of the plurality of annular assembly parts 41, and a plurality of support plates 43 are fixedly installed above the fixed plate 42 through columns 44. The culture fluid storage container 8 and the oxygen storage container 9 are installed above the support plates 43 to support and fix the culture fluid storage container 8 and the oxygen storage container 9.

[0057] Specifically, in order to increase the stability of the fermentation tank 51 after installation and ensure that it will not slip between the vibration ring frame 410 due to vibration, a plurality of positioning slots 4100 are provided on the inner side of the upper surface of the vibration ring frame 410, and positioning blocks 510 that can engage with the positioning slots 4100 are provided one by one at the upper edge position of the fermentation tank 51. The positioning blocks 510 are engaged in the positioning slots 4100, and the upper surface of the vibration ring frame 410 is rotatably installed with a locking pressure piece 4101. The shaft connecting the locking pressure piece 4101 and the vibration ring frame 410 is sleeved with a torsion spring. In this way, after the fermentation tank 51 is installed, the locking pressure piece 4101 can be rotated and pressed above the edge of the fermentation tank 51, so as to achieve auxiliary fixation of the fermentation tank 51, thereby increasing its stability.
