[0028] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0029] Please refer to Figures 1 to 3 , this application provides a technical solution: a microbial high-efficiency temperature-controlled fermentation device, including a fermentation tank 1, a temperature control component 200 for temperature control is installed inside the fermentation tank 1, and a uniform component 300 for uniform temperature transfer is installed inside the fermentation tank 1; through the combined use of the temperature control component 200 and the uniform component 300 inside the fermentation tank 1, the uniformity of the temperature and solubility of each part of the product can be further improved through structural improvement. By specifically stirring the microbial fermentation broth near the heat source, the flow rate of this part of the liquid is increased, thereby increasing the efficiency of temperature transfer and the flow rate of this part of the liquid, enabling the liquid with a higher temperature to quickly mix with the liquid in other parts, thereby improving the uniformity of the temperature inside the microbial solution. At the same time, through the targeted stirring inside, the probability of precipitation is reduced, making the overall uniformity of the product consistent, thereby effectively enhancing the practicability of the microbial fermentation device.

[0030] In this embodiment, the uniformity component 300 is a structure for efficiently transferring the solution temperature and preventing sinking to the bottom.

[0031] As Figure 1 and Figure 3 shown, the uniformity component 300 includes a driving rod 301 rotatably connected to the inside of the fermentation tank 1 through a bearing, four extension rods 302 fixed to the outside of the driving rod 301, a straight rod 303 fixed to the outside of the extension rod 302 and on the side away from the driving rod 301, a scraping plate 304 fixed to the bottom of the extension rod 302, a support rod 305 fixed to the outside of the driving rod 301 and the other ends of which are respectively fixedly connected to the outside of the corresponding straight rod 303, several fixing rods 306 fixed between the outside of the support rod 305 and the outside of the corresponding extension rod 302, four connecting rods 307 fixed to the outside of the driving rod 301 and the other ends of which are respectively fixedly connected to the outside of the corresponding straight rod 303, several stirring plates 308 fixed to the outside of the connecting rod 307, and several stirring members 400 sleeved on the outside of the driving rod 301.

[0032] It should be noted that the number of the stirring members 400 is three; the stirring members 400 include a fixed sleeve 401 sleeved on the outside of the driving rod 301, four mounting rods 402 fixed to the outside of the fixed sleeve 401, a stirring plate 403 fixed to the end of the mounting rod 402 away from the driving rod 301, and several support plates 404 fixed to the outside of the mounting rod 402; four support plates 404 are fixedly arranged on the outside of each mounting rod 402 and are symmetrically distributed up and down, so that the stirring members 400 can perform effective stirring work and enable the solution to flow efficiently.

[0033] In addition, the bottom of the scraping plate 304 is attached to the inner bottom wall of the fermentation tank 1, and the thickness of the bottom of the scraping plate 304 is less than that of the top, so that the scraping plate 304 can play a good role in pushing the solution on the inner bottom wall of the fermentation tank 1. Two fixing rods 306 are fixed between the outside of each support rod 305 and the outside of the extension rod 302, so that the fixing rods 306 can play an auxiliary fixing role for the support rod 305 and the extension rod 302. Six stirring plates 308 are fixedly arranged on the outside of each connecting rod 307 and are symmetrically distributed up and down, so that the stirring plates 308 can stir the solution in the space on the opposite side of the straight rod 303 and the driving rod 301, enabling efficient heat transfer.

[0034] In this embodiment, the temperature control component 200 is a structure for effectively heating the solution.

[0036] It should be noted that a filling cavity for filling the heat preservation layer 201 is opened inside the fermentation tank 1. The heat preservation layer 201 can be made of materials with heat preservation ability such as polyurethane foam, so that the heat preservation layer 201 can play a role in heat preservation for the internal solution of the fermentation tank 1.

[0037] In addition, the installation groove 202 is opened around the inner side of the fermentation tank 1 and is annular. A heater for controlling the temperature and the on-off state of the heating pipe 204 is fixedly installed on the outer side of the fermentation tank 1. The end of the heating pipe 204 penetrates the inner side of the fermentation tank 1 and is fixedly connected to the output end of the heater, so that the heater can play a good role in heating the internal solution of the fermentation tank 1 through the heating pipe 204. Among them, the annular heat conduction plate 203 can be made of stainless steel alloy plate, and the heating pipe 204 is made of copper pipe or aluminum pipe, so that it has good heat conduction efficiency and heat conduction ability.

[0038] It should also be noted that a speed change gearbox 501 is fixedly installed on the top of the fermentation tank 1, and its output shaft penetrates the top of the fermentation tank 1 and is fixedly connected to the top end of the driving rod 301. A driving mechanism 502 with its output shaft fixedly connected to the input shaft of the speed change gearbox 501 is fixedly installed on the outer side of the speed change gearbox 501. The driving mechanism 502 can be a servo motor, so that the driving mechanism 502 can drive the driving rod 301 to move through the speed change gearbox 501. An inlet pipe 503 penetrates and is fixedly connected to the top of the fermentation tank 1, and two discharge pipes 504 penetrate and are fixedly connected to the bottom of the fermentation tank 1. An electric valve 505 is fixedly installed on the outer side of the discharge pipe 504. The two discharge pipes 504 are symmetrically distributed left and right, and a connecting flange is fixed to the outer side of the end of the discharge pipe 504, so that the discharge pipe 504 can be connected to other pipes through the connecting flange, or the solution inside the fermentation tank 1 can be directly discharged through the discharge pipe 504.

[0039] In addition, four uniformly distributed feet 6 are fixedly installed at the bottom of the fermentation tank 1. The feet 6 include movable rods, movable sleeves, buffer springs, and dampers. The two ends of the movable rod are respectively fixedly connected to the bottom of the fermentation tank 1 and the top of the buffer spring. The top of the movable sleeve is open, and the inner side of the movable sleeve is provided for the corresponding movable rod to slide. The bottom of the buffer spring is fixedly connected to the inner bottom wall of the corresponding movable sleeve. The damper is located inside the corresponding buffer spring, and the two ends of the damper are respectively fixedly connected to the bottom end of the movable rod and the inner bottom wall of the movable sleeve, so that the movable rod can buffer and damp the fermentation tank 1 through the buffer spring and the damper.

[0040] At the same time, a main control panel 7 is fixedly installed on the front of the fermentation tank 1. The main control panel 7 is a publicly available control device, which can be a PLC programmable controller, and the main control panel 7 is used to display data and control electronic devices.

[0041] The working principle of the above embodiment is as follows:

[0042] When controlling the temperature fermentation of the microbial solution, the solution is injected into the fermentation tank 1 through the inlet pipe 503. The driving mechanism 502 is started to drive the speed change gearbox 501 to rotate, so that the driving rod 301 rotates. The heating pipe 204 is started to heat the solution inside the fermentation tank 1 through the annular heat conducting plate 203, and the temperature is monitored in real time under the monitoring of the temperature sensor 205 to facilitate controlling the switch of the heating pipe 204. Under the action of the straight rod 303, the solution near the annular heat conducting plate 203 can be stirred to drive it to be mixed with the solution in other parts, so as to complete the temperature transfer. Under the action of the scraper 304, the solution on the inner bottom wall of the fermentation tank 1 can be stirred to prevent it from generating precipitates due to continuous sedimentation. Under the combined stirring action between the stirring plate 308 and the stirring member 400, the solution inside the fermentation tank 1 can be effectively stirred, enabling the temperature to be transferred efficiently, and minimizing the stirring dead angle as much as possible, so that the temperature and the concentration of each part inside the microbial solution can become very uniform, which is conducive to the high-quality and efficient progress of the fermentation work.

[0043] Compared with the prior art, the microbial high-efficiency temperature-controlled fermentation equipment can further improve the uniformity of temperature and solubility of each part of the product through the combined use of the temperature control component 200 and the uniformity component 300 inside the fermentation tank 1. By specifically stirring the microbial fermentation broth near the heat source, the flow rate of this part of the liquid is increased, thereby increasing the efficiency of heat transfer and the flow rate of this part of the liquid, enabling the liquid with a higher temperature to quickly mix with the liquid in other parts, so as to improve the uniformity of the temperature inside the microbial solution. At the same time, through the specific stirring inside, the probability of precipitation is reduced, making the overall uniformity of the product consistent, thus effectively enhancing the practicability of the microbial fermentation equipment and solving the drawback that the temperature control device for microbial fermentation in the prior art is prone to inconsistent uniformity of solubility and temperature of each part of the product due to structural limitations during actual use.

[0044] The electrical components mentioned in the text are all electrically connected to the main controller and the power supply. The provision of the power supply belongs to the common knowledge in the art. The main controller can be a conventional known device such as a computer for control, which can be realized by simple programming by those skilled in the art, and all are existing publicly disclosed electrical connection technologies, so they will not be elaborated in the text.
