Description

Technical Field

[0001] This utility model relates to the field of microbial fermentation equipment technology, specifically to a biological fermentation device. Background Technology

[0002] Bio-fermentation is a process in which microorganisms convert organic matter into target products. In this process, microorganisms carry out metabolic activities under suitable environmental conditions, decompose substrates and release the required biological products. Temperature control plays a crucial role in bio-fermentation. Different microorganisms have different temperature requirements. Temperatures that are too high or too low will inhibit their growth or metabolic activity, or even lead to cell death. Temperatures that are too high will increase the metabolic rate, which may lead to increased oxygen consumption and even inhibit the formation of target products. By precisely controlling the temperature, we can ensure that microorganisms are in the most suitable growth temperature range, thereby improving the yield and quality of the product.

[0003] In existing bio-fermentation devices, the fermentation tank is heated by an external heating pipe. However, the water in the heating pipe loses heat as it flows through the channel, and the temperature of the water decreases after recirculation, affecting the temperature of the hot water in the tank. This results in uneven heating in the fermentation tank, making it difficult to maintain the fermentation temperature and reducing the efficiency of bio-fermentation. Utility Model Content

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0040] In the description of this application, the term "for example" is used to mean "used as an example, illustration, or description." Any embodiment described as "for example" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to implement and use the present invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0041] In one specific implementation, such as Figure 1-4 As shown, the bio-fermentation device provided by this utility model includes a fermenter 1, a circulating pump box 6, a heating box 7, and a heating assembly. The fermenter 1 has an inner cylinder with a accommodating cavity, heat-conducting pipes disposed on the outer periphery of the inner cylinder, and an insulation layer 20 covering the heat-conducting pipes. The fermenter 1 is the core component of the bio-fermentation device, and its main function is to provide a suitable growth and metabolic environment for microorganisms. The inner cylinder is the main body of the fermenter 1, having a accommodating cavity for containing the fermentation culture medium and microorganisms. The heat-conducting pipes are disposed on the outer periphery of the inner cylinder for regulating the temperature inside the fermenter 1 using a heat medium (such as hot water or steam; in this embodiment, hot water is used as an example). The insulation layer 20 covers the outer layer of the heat-conducting pipes, providing insulation and reducing heat loss to ensure a stable temperature inside the fermenter 1.

[0042] The function of the circulating pump box 6 is to provide power to the heat transfer pipeline and realize the circulation of the heat transfer medium. The circulating pump box 6 is equipped with a water pump, which drives the impeller to rotate through a motor, generating centrifugal force, thereby driving the liquid (heat transfer medium) to circulate in the heat transfer pipeline. The outlet of the circulating pump box 6 is connected to the inlet of the heat transfer pipeline through the inlet pipe 4, and the inlet is connected to the outlet of the heat transfer pipeline through the outlet pipe 5, forming a closed circulation pipeline system.

[0043] The circulating pump box 6 is installed in the heating box 7, and the inner cavity of the circulating pump box 6 is connected to the inner cavity of the heating box 7. A first turbulence structure is installed in the heating box 7, and the heating component is installed in the heating box 7.

[0044] The heating chamber 7 provides heat to the heat medium within its inner cavity. After heating, the heat medium enters the circulating pump box 6, where it flows freely. The heating assembly, installed inside the heating chamber 7, converts electrical energy into heat energy to heat the heat medium. A first turbulence structure, also installed inside the heating chamber 7, creates turbulence in the heat medium during heating, improving heat transfer efficiency and ensuring uniform temperature. The heating assembly is the core component of the heating chamber 7 and can be composed of heating wires and insulating materials. Based on Joule's law, when current passes through the heating wires, the wires heat up due to resistance, thus converting electrical energy into heat energy.

[0045] The top of the heating box 7 is provided with a water inlet 12 to facilitate the addition of heat medium into the heating box 7. A sealing cap 13 is provided on the water inlet 12.

[0046] To improve heat conduction and heating efficiency of the fermentation chamber, the heat conduction pipeline is a spiral pipeline 3, which is wound as densely as possible around the outer circumference of the inner cylinder. The inlet of the spiral pipeline 3 is connected to the water inlet pipe 4, and the outlet of the spiral pipeline 3 is connected to the water outlet pipe 5. After the heat medium is heated, it exchanges heat with the fermentation chamber through the spiral pipeline.

[0047] Furthermore, the fermenter 1 also includes a heat-conducting metal layer disposed between the spiral pipe 3 and the inner cylinder. Specifically, the heat-conducting metal layer can be a heat-conducting copper sheet 21, which can be wholly or partially wrapped around the outer periphery of the inner cylinder to increase the contact area, thereby improving heat conduction efficiency and the uniformity of heat transfer. It is understood that the fermenter 1 is typically a cylindrical structure, with an inlet 16 on the top cover 15 and an outlet pipe 22 at the bottom.

[0048] In order to improve the uniformity of the heat medium in the fermenter 1 and thus ensure the uniform temperature inside the fermenter 1, the biological fermentation device also includes a second turbulence structure. The second turbulence structure is installed in the accommodating cavity and moves under the drive of the turbulence motor 17 to turbulent the liquid in the accommodating cavity.

[0049] Specifically, the second turbulence structure includes a stirring rod 18 and a second stirring blade 19. The stirring rod 18 is connected to the turbulence motor 17, and the second stirring blade 19 is mounted on the stirring rod 18 and moves with it. During operation, the turbulence motor 17 starts, driving the stirring rod 18 to rotate, which in turn drives the second stirring blade 19 to move around the stirring rod 18 as its rotation axis, thus achieving turbulence. Multiple sets of second stirring blades 19 can be provided, with each set arranged at intervals along the axial direction of the stirring rod 18. Each set of second stirring blades 19 includes at least two blades, which are arranged at intervals around the circumference of the stirring rod 18 to improve the turbulence effect.

[0050] Specifically, the heating assembly includes a drive box 8 and a heating tube 9; wherein, the drive box 8 is installed on the outer wall of the heating box 7, and the heating tube 9 is connected to the drive box 8 in a transmission manner and is heated under the action of the drive box 8. The drive box is a collective term for two driving structures contained therein, one acting on the heating tube and the other acting on the rotating rod. The heating tube heats up by electric heating, and there are uniformly distributed high-temperature resistance wires inside the heating tube.

[0051] The aforementioned first turbulence structure includes a rotating rod 10 and a first stirring blade 11. The rotating rod 10 is connected to the drive box 8 and rotates under the drive of the drive box 8. The first stirring blade 11 is mounted on the rotating rod 10 and moves with the rotating rod 10. The heating tube 9 is a spiral tube, and the rotating rod 10 passes axially through the spiral tube. Specifically, the rotating rod is connected to the output end of a servo motor inside the drive box.

[0052] The bio-fermentation device provided by this utility model, during operation, involves the activation of a water pump in the circulating pump box 6, which drives the water flow in the heating tank 7 to be injected through the inlet pipe 4 and discharged through the outlet pipe 5 via the heat-conducting pipe, forming a circulating flow. When the heating component is activated, it heats the liquid in the heating tank 7. Simultaneously, the first turbulence structure is activated to agitate the liquid, raising its temperature to the required level. The activation of the circulating pump box 6 drives the liquid to circulate within the heat-conducting pipe, and the continuous heating by the heating component, combined with the agitation by the first turbulence structure, ensures a uniform and constant temperature for the liquid. Thus, the bio-fermentation device provided by this utility model solves the problems of low temperature in the fermentation tank 1 and uneven heating temperature, making it difficult to maintain the fermentation temperature, which are caused by a decrease in the temperature of the circulating water in the prior art. It improves the uniformity of the heating temperature, ensures that the temperature remains approximately constant during the fermentation process, and avoids the impact of a decrease in the temperature of the circulating water on the fermentation temperature, thereby improving the efficiency of bio-fermentation.

[0053] For ease of understanding, the structure and working process of the bio-fermentation device provided by this utility model will be briefly described below using two specific embodiments as examples.

[0054] Example 1

[0055] Please continue to refer to this. Figures 1-4 The biological fermentation device provided by this utility model includes a fermenter 1 and a heating box 7. The fermenter 1 has an inner cavity 2, and a spiral pipe 3 is installed on the side of the inner cavity 2. A water inlet pipe 4 is installed at one end of the spiral pipe 3, and a water outlet pipe 5 is installed at the other end of the spiral pipe 3. A circulation pump box 6 is connected to one end of the water inlet pipe 4 and the water outlet pipe 5. The circulation pump box 6 is installed in the heating box 7. A drive box 8 is installed at one end of the heating box 7. A heating pipe 9 is installed at one end of the drive box 8. A rotating rod 10 is rotatably installed on the side of the drive box 8. A first stirring blade 11 is installed on the side of the rotating rod 10. A water inlet 12 is opened on the top of the heating box 7. A sealing cap 13 is installed at one end of the water inlet 12. A touch panel 14 is installed on the side of the heating box 7. The touch panel 14 is compatible with the drive box 8. A heat insulation layer 20 is installed on the side of the fermenter 1. A heat-conducting copper sheet 21 is installed inside the fermenter 1. The spiral pipe 3 is compatible with the heat-conducting copper sheet 21.

[0056] When the temperature needs to be adjusted during biological fermentation, the desired temperature is set via the touch panel 14. After setting, the drive box 8 starts, driving the heating tube 9 to heat the liquid in the heating box 7. At the same time, the rotating rod 10 rotates to agitate the first stirring blade 11, making the heat of the liquid evenly mixed. The circulation pump box 6 is started to drive the liquid to be transported. The liquid is transported to the spiral pipe 3 through the water inlet pipe 4, flows along the inner wall of the spiral pipe 3, and is discharged from the water outlet pipe 5 into the heating box 7. The circulation pump box 6 forms a circulation flow. The returned liquid is mixed and warmed by the stirring of the rotating rod 10 and the heating of the heating tube 9, and continues to be transported to the water inlet pipe 4, keeping the temperature of the liquid flowing in the spiral pipe 3 constant. This helps to control the temperature required for biological fermentation and prevents the temperature of the returned liquid from being too low and affecting the fermentation effect. When the liquid flows in the spiral pipe 3, the heat insulation layer 20 on the outside of the fermentation tank 1 helps the fermentation tank 1 retain heat. The heat-conducting copper sheet 21 in the fermentation tank 1 introduces the temperature in the spiral pipe 3 into the fermentation tank 1 more quickly, improving the applicability of the device.

[0057] Example 2

[0058] like Figure 2 and Figure 3As shown, a top cover 15 is installed on the top of the fermentation tank 1. A feed inlet 16 is installed at one end of the top cover 15. A turbulence motor 17 is installed on the top cover 15. A stirring rod 18 is installed at one end of the turbulence motor 17. Multiple second stirring blades 19 are installed on the side of the stirring rod 18. A discharge pipe 22 is installed at the bottom of the fermentation tank 1. The feed inlet 16 is adapted to the discharge pipe 22. When the turbulence motor 17 on the top of the top cover 15 is started, it drives the stirring rod 18 to rotate, which in turn drives the second stirring blades 19 to stir the biological fermentation material, making the material more evenly mixed, which helps to distribute heat, improves the fermentation efficiency, and thus improves the production efficiency. After the biological fermentation is completed, it is discharged through the discharge pipe 22 for easy collection by the operator. The remaining features are the same as in Example 1.

[0059] When the bio-fermentation temperature needs to be adjusted, the desired temperature is set via the touch panel 14. After setting, the drive box 8 starts, driving the heating tube 9 to heat the liquid in the heating box 7. At the same time, the rotating rod 10 rotates to agitate the first stirring blade 11, ensuring the liquid's heat is evenly mixed. The circulation pump box 6 is then activated to transport the liquid. The liquid is transported through the inlet pipe 4 into the spiral pipe 3, flowing along the inner wall of the spiral pipe 3, and then discharged from the outlet pipe 5 back into the heating box 7. The circulation pump box 6 forms a circulating flow. The returned liquid is mixed and reheated by the stirring of the rotating rod 10 and the heating tube 9, and continues to be transported to the inlet pipe 4, maintaining a constant temperature for the liquid flowing in the spiral pipe 3. This helps control the temperature required for biological fermentation and prevents the low temperature of the reflux liquid from affecting the fermentation effect. The turbulence motor 17 on the top of the top cover 15 drives the stirring rod 18 to rotate, which in turn drives the second stirring blade 19 to stir the biological fermentation material, making the material more evenly mixed, which helps with heat distribution, improves fermentation efficiency, and thus improves production efficiency. When the liquid flows in the spiral pipe 3, the heat insulation layer 20 on the outside of the fermentation tank body 1 helps the fermentation tank body 1 retain heat. The heat-conducting copper sheet 21 inside the fermentation tank body 1 introduces the temperature in the spiral pipe 3 into the fermentation tank body 1 more quickly, improving the applicability of the device. After the biological fermentation is completed, it is discharged through the discharge pipe 22 for easy collection by the operator.
