[0002] Fermentation refers to the process in which people use the life activities of microorganisms under aerobic or anaerobic conditions to prepare microbial cells themselves or direct metabolites or secondary metabolites. It is widely used in the food industry, biological and chemical industries. Microbial fermentation is a biological process that uses the special metabolic pathways of microorganisms to convert raw materials into target products.

[0003] Currently, fermentation tanks are required to be able to ferment bacteria efficiently and be easy to use. However, existing fermentation tanks only have heating devices and insulation layers around the perimeter of the tank, resulting in a large temperature difference between the center and edge temperatures of the tank. Furthermore, the fermentation temperature inside the tank cannot be quickly adjusted, resulting in substandard fermentation quality. Utility model patent No. CN213803819U utilizes circulating fluid to control the temperature of the fermentation tank by injecting it between the insulation box and the fermentation tank body. While the circulating fluid temperature is controllable, this technical solution has a small heat exchange contact area, making efficient and stable heat exchange impossible.

[0004] Therefore, how to develop a microbial fermentation box that can heat the material evenly has become a technical problem that needs to be solved urgently. Utility Model Content

[0026] With reference to the accompanying drawings, Figure 1 This is a schematic diagram of the main structure of the microbial fermentation box of the utility model; Figure 2 This is a schematic diagram of the main cross-sectional structure of the exhaust propeller pipe of the present invention; Figure 3 This is a schematic diagram of the top view of the exhaust propeller pipe of the present invention. Example

[0027] like Figure 1 As shown, a microbial fermentation chamber comprises a support 1, a fermentation chamber body 2, heat exchange tubes 3, and a temperature control mechanism 4. The fermentation chamber body 2, used for microbial fermentation and growth, is mounted to the top plate of the support 1 via bottom bolts. The top cover of the fermentation chamber body 2 is provided with an inlet 201 and an exhaust pipe 203. The inlet 201 allows for the introduction of raw materials and bacterial strains, while the exhaust pipe 203 discharges the reacted air or passes the remaining air to an exhaust gas treatment unit for deodorization and detoxification. A discharge port 202 is provided at the bottom of the fermentation chamber body 2, equipped with a shutoff valve to control the discharge. The heat exchange tubes 3 are coiled within the fermentation chamber body 2, directly contacting the liquid microbial agent. The temperature control mechanism 4 is mounted on the support 1 and located next to the fermentation chamber body 2. The temperature control mechanism 4 supplies a circulating medium to the heat exchange tubes 3 for temperature regulation. The temperature control mechanism 4 uses an evaporator to cool the circulating medium and a heater to heat the circulating medium.

[0028] Specifically, the circulating medium here can be pure water or ethylene glycol solution.

[0029] By providing an immersed heat exchange tube 3 within the inner cavity of the fermentation chamber body 2, a larger heat exchange area is achieved, improving temperature control. By providing a temperature control mechanism 4 capable of both heating and cooling to control the temperature of the circulating medium, the inoculum in the inner cavity of the fermentation chamber body 2 is ensured to be within a suitable fermentation temperature range. By modifying the internal structure of the fermentation chamber, this utility model achieves the effect of easily adjustable temperature and uniform heating during the fermentation process.

[0030] In a specific implementation of this embodiment, Figure 1 As shown, the heat exchange tube 3 is a spiral coil, and a corresponding receiving groove for the heat exchange tube 3 is formed on the inner wall of the fermentation box body 2. The top end of the heat exchange tube 3 is connected to the return port of the temperature control mechanism 4 through a return pipe, and the bottom end of the heat exchange tube 3 is connected to the liquid outlet of the temperature control mechanism 4 through a liquid outlet pipe.

[0031] Specifically, if Figure 1 As shown, a heat-insulating layer is provided on the side wall of the fermentation box body 2, and heat-insulating protective sleeves are sleeved on the outer walls of the liquid return pipe and the liquid outlet pipe.

[0032] By configuring the heat exchange tube 3 as a spiral coil, the immersion length of the heat exchange tube 3 can be increased, improving heat exchange efficiency. By providing a spiral receiving groove corresponding to the heat exchange tube 3 on the inner wall of the fermenter body 2, the heat exchange tube 3 is supported and secured, preventing it from falling out. By adding a thermal insulation layer to the side wall of the fermenter body 2 and attaching a thermal insulation protective sleeve to the outer wall of the return and outlet pipes, the cooling and heat losses of the circulating medium can be reduced.

[0033] Specifically, if Figure 1 As shown, a temperature sensor 9 is installed on the inner wall of the fermentation chamber body 2. This temperature sensor 9 provides feedback on the fermentation temperature of the inoculum to the equipment's electronic control system. This electronic control system can utilize a temperature control instrument or a PLC control system with temperature monitoring capabilities. This is prior art and will not be discussed further. Furthermore, there are three temperature sensors 9, located at the top, middle, and bottom of the fermentation chamber body 2. Example

[0034] When the microbial agent fermentation box of the present invention is used for aerobic fermentation microbial agent cultivation and proliferation, the aeration performance is improved on the basis of the above embodiment 1 to form this embodiment.

[0035] like Figures 1 to 3As shown, the inoculum fermentation chamber of the present invention also includes an air intake assembly 5, a main air intake pipe 6, and an air distribution component. The air intake assembly 5 is mounted on the top cover of the fermentation chamber body 2. The air outlet of the air intake assembly 5 is connected to the top opening of the main air intake pipe 6. The main air intake pipe 6 is vertically positioned in the middle of the inner cavity of the fermentation chamber body 2. A support base is positioned in the middle of the inner wall of the bottom plate of the fermentation chamber body 2 to support the bottom end of the main air intake pipe 6. The air distribution component is mounted on the bottom opening of the main air intake pipe 6 and evenly discharges clean air into the inner cavity of the fermentation chamber body 2.

[0036] Specifically, the air intake assembly 5 includes an air pump, a filter, and a sterilization box. The filter filters through a filter paper core, and the sterilization box sterilizes by ultraviolet light irradiation. Air drawn into the air inlet of the air intake assembly 5 passes through the filter and sterilization box in sequence, and is then pumped into the main air intake pipe 6 by the air pump.

[0037] Air is supplied to the air distribution assembly via a main air inlet pipe 6, vertically positioned in the middle of the fermentation chamber body 2. Clean air is evenly distributed throughout the chamber around the main air inlet pipe 6, rapidly replenishing dissolved oxygen. A filter and sterilizing chamber are incorporated into the air inlet assembly 5, reducing the introduction of dust and impurities and preventing the impact of bacteria on the inoculum.

[0038] In a specific implementation of this embodiment, Figure 2 and Figure 3 The air distribution component comprises an exhaust paddle pipe 7, a stop 602 at the bottom of the main intake pipe 6, and radially defined air vents 601. The exhaust paddle pipe 7 is rotatably sleeved onto the main intake pipe 6, with its bottom end abutting against the stop 602 and its top end secured by a retaining spring 8. Specifically, the intake pipe 6 also has a retaining spring groove above the stop 602, into which the retaining spring 8 fits. The air vents 601 connect to the exhaust paddle pipe 7, which distributes air while rotating.

[0039] Specifically, if Figure 2 and Figure 3 The exhaust paddle pipe 7 comprises a hub 701, an exhaust stirring branch pipe 702, an air nozzle 703, and a bearing sleeve 705. The two exhaust stirring branches 702 are axially symmetrically arranged on the outer cylindrical sidewall of the hub 701. Multiple air nozzles 703 are evenly spaced and arranged on one side of the exhaust stirring branch pipe 702. The air nozzles 703 on the two exhaust stirring branches 702 are arranged symmetrically about the central axis of the hub 701, ensuring that the air outlet directions of the air nozzles 703 on the two exhaust stirring branches 702 are all along the same rotational direction. The hub 701 is rotatably connected to the main intake pipe 6 via the bearing sleeve 705.

[0040] Specifically, if Figure 2 and Figure 3The bearing sleeve 705 is made of a polytetrafluoroethylene composite material, which has excellent corrosion resistance, low friction coefficient, and wear resistance. An annular groove 706 is formed on the side of the bearing sleeve 705 facing the vent 601. The bearing sleeve 705 and the wheel hub 701 are connected to the exhaust stirring branch pipe 702 via a positioning tube 704.

[0041] By rotatably attaching the exhaust paddle tube 7 to the main intake pipe 6, the exhaust paddle tube 7 can be driven to rotate while aeration is being performed, thereby stirring the inoculum within the fermentation chamber body 2, achieving uniform fermentation of the material and temperature. The bearing sleeve 705, constructed from a polytetrafluoroethylene composite material, extends the equipment's service life. The annular groove 706 ensures that pressurized clean air is continuously output from the vent 601 during rotation.

[0042] The operating principle of the inoculum fermentation chamber in this embodiment is as follows: When the temperature sensor 9 detects that the fermentation temperature of the inoculum in the fermentation chamber body 2 deviates from the set temperature, it transmits a signal to the equipment's electronic control system, which activates the temperature control mechanism 4, which then provides a cooling or heating circulating medium to the heat exchange tube 3. Within the fermentation chamber body 2, the heat exchange tube 3 exchanges heat with the inoculum, bringing the fermentation temperature back within the set range, and then deactivates the temperature control mechanism 4. During aerobic fermentation, clean air must be regularly introduced into the inoculum to promote fermentation. The equipment's electronic control system activates the air intake assembly 5. Air drawn into the inlet of the air intake assembly 5 passes through the filter and the sterilization chamber, and is then pumped into the main air intake pipe 6. The compressed clean air then enters the annular groove 706 through the vent 601, passes through the positioning pipe 704, and enters the exhaust and agitation branch pipe 702. Finally, it is ejected from the air nozzle 703 on the side of the exhaust and agitation branch pipe 702 into the inoculum. During the air jetting process, the reaction force pushes the exhaust stirring branch pipe 702 to rotate around the main air inlet pipe 6, and the rotating exhaust stirring branch pipe 702 stirs the bacterial agent.

[0043] In summary, the present invention's microbial fermentation tank achieves a larger heat exchange area and improves temperature control by providing immersed heat exchange tubes 3 within the inner cavity of the fermentation tank body 2. By providing a temperature control mechanism 4 capable of both heating and cooling to control the temperature of the circulating medium, the microbial fermentation tank within the inner cavity of the fermentation tank body 2 can be ensured to be within a suitable fermentation temperature range. By modifying the internal structure of the fermentation tank, the present invention's microbial fermentation tank achieves the effect of easily regulating the temperature and uniform heating during the microbial fermentation process. Furthermore, by configuring the heat exchange tubes 3 as spiral coils, the immersion length of the heat exchange tubes 3 can be increased, improving heat exchange efficiency. By providing spiral receiving grooves corresponding to the heat exchange tubes 3 on the inner wall of the fermentation tank body 2, the heat exchange tubes 3 are supported and secured, preventing them from falling out. By adding a thermal insulation layer to the side walls of the fermentation tank body 2 and attaching thermal insulation protective sleeves to the outer walls of the return and outlet pipes, the cooling and heat losses of the circulating medium can be reduced. Air is supplied to the air distribution component through a main air inlet pipe 6 vertically arranged in the middle of the inner cavity of the fermentation box body 2, and clean air is evenly aerated to the entire inner cavity around the main air inlet pipe 6, so that the dissolved oxygen is quickly replenished. By setting the filter and the sterilization box in the air inlet component 5, the introduction of dust and impurities is reduced, and the influence of miscellaneous bacteria on the bacterial agent is avoided. By setting the exhaust paddle pipe 7 rotatably sleeved on the main air inlet pipe 6, the exhaust paddle pipe 7 can be driven to rotate while aerating, thereby completing the stirring of the bacterial agent in the inner cavity of the fermentation box body 2, and achieving uniform fermentation of materials and temperature. The bearing sleeve 705 made of polytetrafluoroethylene composite material increases the service life of the equipment. Through the setting of the annular groove 706, the pressurized clean air output by the vent 601 can be continuously obtained during the rotation process.
