Abstract
Description
Technical Field
[0001] This utility model relates to the field of fermentation technology, specifically to a self-circulating temperature control disturbance mechanism for fermentation materials. Background Technology
[0002] Fermentation engineering, as an important branch of biotechnology, plays a crucial role in various fields such as food, medicine, environmental protection, and agriculture. During fermentation, temperature control, material mixing uniformity, and dissolved oxygen (DO) content are key factors affecting microbial growth rate and product conversion efficiency. Especially when dealing with high-viscosity fermentation systems, traditional stirring devices often suffer from uneven heat transfer, low mixing efficiency, and insufficient dissolved oxygen, which seriously restricts fermentation effect and product quality.
[0003] Existing fermentation equipment mostly uses mechanical stirring combined with external heating for material mixing and temperature control. However, such systems often struggle to achieve precise control over the internal temperature of the material, especially in high-viscosity systems where localized supercooling can easily occur, leading to decreased or even inactivated microorganisms. Furthermore, traditional aeration methods often rely on bottom-mounted air distribution plates, and uneven gas distribution can create excessive dissolved oxygen gradients, limiting the optimal growth environment for aerobic microorganisms.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0005] In view of the problems in the related technologies, this utility model proposes a self-circulating temperature control disturbance mechanism for fermentation materials to overcome the above-mentioned technical problems existing in the existing related technologies.
[0006] Therefore, the specific technical solution adopted by this utility model is as follows:
[0007] A self-circulating temperature control disturbance mechanism for fermentation materials includes a mounting plate, a hollow shaft connected to the center of the mounting plate via a bearing, a connecting rod connected to the outside of the hollow shaft, a cavity inside the connecting rod communicating with the hollow shaft, a spiral strip connected to the connecting rod, a conveying pipe connected below the spiral strip, a micro-orifice nozzle on the conveying pipe, and heat transfer oil inside the hollow shaft.
[0008] Furthermore, a heating rod is installed inside the hollow shaft, and the top of the heating rod is connected to the connecting cover. The connecting cover is connected to the hollow shaft by bolts. A temperature sensor is installed inside the hollow shaft, and the temperature sensor is connected to the controller by wires. The controller is connected to the heating rod by wires.
[0009] Furthermore, one end of the delivery pipe passes through the hollow shaft and the connecting cover and is connected to the connecting pipe. One end of the connecting pipe is connected to the filter, and one side of the filter is connected to the air compressor through the air inlet pipe.
[0010] Furthermore, a pressure regulating valve is installed on the connecting pipe.
[0011] Furthermore, a driven gear is connected to the hollow shaft, one side of which meshes with the driving gear. The driving gear is connected to the output shaft of the drive motor, and the drive motor is connected to the fixed frame.
[0012] Furthermore, the mounting bracket is connected to the mounting plate.
[0013] Furthermore, a tank is bolted to the bottom of the mounting plate, and a hollow shaft is located inside the tank.
[0014] Furthermore, the filter and air compressor are located on one side of the mounting plate.
[0015] Furthermore, the mounting plate is equipped with a feed inlet.
[0016] The beneficial effects of this utility model are as follows:
[0017] (1) This device heats the heat transfer oil by introducing it into the hollow shaft and cavity, and heating it with heating rods. Combined with a temperature sensor and controller, it forms a closed-loop temperature control system that can monitor and adjust the temperature of the hollow shaft and its connecting components in real time. During the rotation of the hollow shaft and connecting rod, their surfaces are in full contact with the material, evenly transferring heat to the entire tank interior. This effectively avoids localized overheating or cold zones, improving the stability of the fermentation process. Furthermore, by setting spiral strips, it achieves efficient stirring while guiding the material to flow along the spiral direction, promoting the overall self-circulation of the material and reducing dead zones in the stirring process.
[0018] (2) By setting up an air compressor, filter, and nozzle, the gas output from the air compressor can be purified by the filter, enter the connecting pipe through the air inlet pipe, and then be transported to the microporous nozzle through the delivery pipe to uniformly release fine bubbles into the tank. This design not only improves the dispersion of gas in the fermentation liquid, but also enhances the turbulence effect by driving the liquid flow through the rising bubbles, thereby significantly increasing the dissolved oxygen content and providing a good environment for the growth of aerobic microorganisms.

[0029] like Figures 1-4As shown, the fermentation material self-circulating temperature control disturbance mechanism according to an embodiment of this utility model includes a mounting plate 1, which serves as the base of the entire mechanism, providing support and fixation. A hollow shaft 2 is connected to the center of the mounting plate 1 via a bearing; this shaft serves as both a drive shaft and a heat transfer oil channel, simultaneously housing a heating rod 9 and a temperature sensor 11. A connecting rod 3 is connected to the outside of the hollow shaft 2, and the connecting rod 3 has a cavity 4 inside, connecting the hollow shaft 2 to a spiral strip 5, which also serves as a heat transfer oil channel. The cavity 4 communicates with the hollow shaft 2. Heat transfer oil is stored inside the hollow shaft 2 as a medium to transfer heat and maintain a consistent material temperature. A heating rod 9 is located inside the hollow shaft 2, providing a heat source for the heat transfer oil and maintaining the set working temperature. The top of the heating rod 9 is connected to a connecting cover 10, which is bolted to the hollow shaft 2 for easy disassembly. A temperature sensor 11 is located inside the hollow shaft 2. The temperature of the heat transfer oil is monitored in real time and fed back to the controller 12. The temperature sensor 11 is connected to the controller 12 via a wire. The controller 12 is connected to the heating rod 9 via a wire, receives the signal from the temperature sensor 11, and controls the working state of the heating rod 9 to achieve closed-loop temperature control. The connection between the wire and the controller 12 adopts a rotary joint design, which allows the hollow shaft 2 to rotate freely without affecting the transmission of electrical signals. A driven gear 18 is connected to the hollow shaft 2. One side of the driven gear 18 is meshed with the driving gear 19, which is used to transmit the power of the drive motor 20 to the hollow shaft 2 through the gear transmission system. The driving gear 19 is connected to the output shaft of the drive motor 20. The drive motor 20 is used to provide a power source to make the hollow shaft 2 and its auxiliary components rotate. The drive motor 20 is connected to the fixing frame 21, which is connected to the mounting plate 1 to provide stable support for the drive motor 20.
[0030] like Figures 1-4As shown, a spiral strip 5 is connected to the connecting rod 3, which is responsible for mixing and agitating the materials. A conveying pipe 6 is connected below the spiral strip 5, which transmits gas from the external supply system to the micro-orifice nozzle 7. The conveying pipe 6 is equipped with a micro-orifice nozzle 7 to release fine bubbles, increase the dissolved oxygen content in the materials, and promote mixing. One end of the conveying pipe 6 passes through the hollow shaft 2 and the connecting cover 10 and connects to the connecting pipe 13. The conveying pipe 6 and the connecting pipe 13 are connected by a rotary joint, allowing relative rotation between them to ensure continuous gas supply. One end of the connecting pipe 13 is connected to a filter 14, which purifies the air or oxygen entering the fermentation system and removes impurities. The filter 14 has a side... The air compressor 16 is connected to the air inlet pipe 15. The air compressor 16 is an oil-free compressor that can provide high-pressure gas for use in the fermentation process. The connecting pipe 13 is equipped with a pressure regulating valve 17 to regulate the pressure of the gas entering the fermentation tank and ensure a stable gas supply.

The filter 14 and the air compressor 16 are located on one side of the mounting plate 1. The mounting plate 1 is equipped with a feed port 8 for adding materials into the fermentation tank. The feed port 8 is equipped with a valve or cover so that it can be closed when not in use to keep the internal environment of the tank body 22 clean and stable.

[0032] In summary, with the help of the above-mentioned technical solution of this utility model, in actual use, the material is added into the tank 22 through the inlet 8. Then, by turning on the air compressor 16, the output gas is ensured to be purified by the filter 14 before entering the connecting pipe 13, and then conveyed to the micro-orifice nozzle 7 through the conveying pipe 6, so as to evenly release fine bubbles into the tank 22. The pressure regulating valve 17 can be adjusted according to actual needs to make the gas pressure entering the conveying pipe 6 reach the set value. Then, by starting the drive motor 20, the rotation of the drive motor 20 can drive the drive gear 19 to rotate. The rotation of the drive gear 19 can drive the driven gear 18 and the hollow shaft 2 to rotate, thereby driving the connecting rod 3 and the spiral strip 5 to rotate, which can push the material along the... The spiral movement achieves uniform mixing and self-circulation of materials. During the stirring process, the heat transfer oil is heated by the heating rod 9, which can evenly transfer heat to the entire interior of the tank 22, allowing the materials to disperse and ensuring the stirring effect. During the heating of the heat transfer oil by the heating rod 9, the temperature of the heat transfer oil can be measured by the temperature sensor 11 and fed back to the controller 12, which can automatically adjust the working state of the heating rod 9 to ensure that the temperature inside the fermentation tank is at a suitable temperature and to ensure the stability of the fermentation process. After the materials are evenly stirred, they can be discharged through the discharge pipe at the bottom of the mixing tank, making it convenient to bag the materials and put them into the warehouse for continued fermentation. The fermentation tank can be replenished with materials to continue operation.
