[0002] Yeast cultures are core microbial strains in bioengineering, food industry, and fisheries. Their cultivation process is highly sensitive to parameters such as temperature, dissolved oxygen, and pH. Taking fish yeast as an example, its optimal growth temperature is 28-32℃, and temperature fluctuations exceeding ±2℃ will significantly affect cell activity and the yield of metabolites.

[0003] The following problems were found in the relevant technology: during the fermentation process of yeast culture, the control of temperature and the effect of mixing will affect the quality. In response, we proposed a temperature-controlled yeast culture fermentation device.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background section of this application, and therefore may include prior art information that does not constitute prior art information known to those skilled in the art. Utility Model Content

[0005] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies. To address the problem of yeast culture fermentation in the prior art, this utility model provides a temperature-controlled yeast culture fermentation device that employs a segmented heating and stirring structure combined with a bulk material structure to improve the fermentation effect of yeast cultures. Its specific technical solution is as follows:

[0006] A temperature-controlled yeast culture fermentation device includes a fermenter. A stirring shaft extending into the inner cavity is rotatably mounted on the top of the fermenter. Stirring frames are uniformly and alternately fitted onto the outer wall of the stirring shaft. A heating rod is embedded in the inner wall of each stirring frame. An annular partition frame is embedded in the top of the inner cavity of the fermenter. An elastic material distribution net is embedded in the inner wall of the annular partition frame. Reset tensioning members connected to the elastic material distribution net are symmetrically arranged on the top of the fermenter. Furthermore, a counter-linking member is provided on the top of the fermenter to drive the two reset tensioning members to move simultaneously and alternately.

[0007] In the above technical solution, the resetting tension member includes a tension rod that passes through the top of the fermenter. The lower end of the tension rod extends into the inner cavity of the fermenter and is fixed to the top of the elastic material net. A limiting seat located above the top of the fermenter is sleeved on the outer wall of the tension rod. An elastic element located between the limiting seat and the top of the fermenter is sleeved on the outer wall of the tension rod.

[0008] The opposing linkage component includes uniformly arranged toothed grooves on the outer wall of the tension rod, and the toothed grooves are located above the limiting seat. The top of the fermentation tank is symmetrically rotatably provided with turntables. The outer wall of the turntables is uniformly provided with half-circumference teeth. Two teeth located on the same side respectively mesh with one of the two sets of toothed grooves arranged opposite each other. The top of the fermentation tank is provided with a synchronous linkage component that drives the two turntables to rotate simultaneously.

[0009] The synchronous linkage component includes symmetrical supports fixed to the top of the fermenter. A movable shaft is rotatably mounted on the support. A turntable is sleeved on the outside of the movable shaft. A driven member is sleeved on the outer wall of the movable shaft extending outside the support. An active member is rotatably mounted on the top of the fermenter. The active member rotates synchronously with the two driven members through a transmission member.

[0012] The top of the fermenter is fixedly fitted with a protective cover that covers the outside of the reset tension member and the opposing linkage member.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This temperature-controlled yeast culture fermentation device:

[0014] 1. By using opposing linkage components, the two points of the elastic material net move up and down alternately with the two reset tensioning components, which causes the yeast culture raw material entering the fermenter cavity to be evenly dispersed by elasticity. The dispersed raw material makes more uniform contact between each raw material, thereby improving the quality of the yeast culture processing.

[0015] Second, as the two turntables rotate synchronously and continuously, the two parts of the elastic bulk material net deform alternately, which improves the dispersion of the raw materials falling on the elastic bulk material net. At the same time, the vibration avoids the raw materials from clogging the mesh, ensuring the smoothness of the feeding process.

[0016] Third, by using three parallel heating rods in different zones, if one heating rod malfunctions, it will not affect the operation of the other two heating rods. By using parallel heating rods in different zones to monitor the temperature inside the fermenter, the fermentation effect of the yeast culture is guaranteed. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The following are specific implementation cases and appendices. Figure 1-4 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0024] A temperature-controlled yeast culture fermentation device includes a fermenter 1. A stirring shaft 2 extending into the inner cavity is rotatably mounted on the top of the fermenter 1. Stirring frames 3 are evenly and alternately fitted onto the outer wall of the stirring shaft 2. A bearing seat is fixed at the center of the fermenter 1, and a bearing is embedded within the bearing seat. The stirring shaft 2 rotates on the top of the fermenter 1 via the bearing. The lower end of the stirring shaft 2 extends into the interior of the fermenter 1, and the top of the stirring shaft 2 extends outward from the top of the fermenter 1 and is fixedly connected to the output shaft of a motor. The motor is fixed to the top of the fermenter 1 via a frame. Connecting seats are sequentially fixedly fitted onto the outer wall of the stirring shaft 2 from top to bottom.

[0025] A rectangular stirring frame 3 is fixedly installed on the outer wall of each connecting seat, and a heating rod 4 is horizontally fixedly installed on the inner wall of each stirring frame 3. The heating rod 4 passes through the stirring frame 3 and is wired through the central cavity of the stirring shaft 2. The heating rod 4 is embedded in the inner wall of the stirring frame 3. The heating rod 4 is connected to an external power source through wires. With three parallel heating rods 4 in different zones, if one heating rod 4 malfunctions, it will not affect the operation of the other two heating rods 4. The temperature inside the fermenter 1 is monitored in different zones through the parallel heating rods 4, thereby ensuring the fermentation effect of the yeast culture.

[0026] An annular partition frame 5 is embedded in the top of the inner cavity of the fermenter 1. An elastic material net 6 is embedded in the inner wall of the annular partition frame 5. Symmetrically arranged on the top of the fermenter 1 are reset and tensioning members connected to the elastic material net 6. Furthermore, the top of the fermenter 1 is equipped with opposing linkage members that drive the two reset and tensioning members to move simultaneously and alternately. The annular partition frame 5 is fixedly embedded inside the fermenter 1 corresponding to the three feed inlets 10. The surface of the elastic material net 6 can elastically deform, allowing it to deform concave and convexly on the annular partition frame 5.

[0027] The two points of the elastic material net 6 are moved up and down alternately by the two reset tensioning components through the opposing linkage components. This causes the yeast culture raw material entering the inner cavity of the fermenter 1 to be evenly dispersed by the elastic force. The dispersed raw material makes more uniform contact between each raw material, thereby improving the quality of the yeast culture processing.

[0028] The resetting tensioning component includes a tension rod 7 penetrating the top of the fermenter 1. The lower end of the tension rod 7 extends into the inner cavity of the fermenter 1 and is fixed to the top of the elastic material net 6. A limiting seat 18 located above the top of the fermenter 1 is sleeved on the outer wall of the tension rod 7. An elastic element 17 located between the limiting seat 18 and the top of the fermenter 1 is sleeved on the outer wall of the tension rod 7. The lower ends of the two tension rods 7 are symmetrically and vertically fixed to the top of the elastic material net 6. The two tension rods 7 penetrate the top of the fermenter 1 and extend outward, allowing the tension rods 7 to slide within the through holes at the top of the fermenter 1.

[0029] The limiting seat 18 is fixedly sleeved on the outer wall of the tension rod 7 through the mounting hole opened in the center, so that the limiting seat 18 moves with the tension rod 7 outside the fermentation tank 1. The elastic element 17 can be a compression spring. The two ends of the elastic element 17 are fixed to the limiting seat 18 and the top of the fermentation tank 1, respectively. The elastic element 17 slides and extends against the outer wall of the tension rod 7.

[0030] It is worth noting that the opposing linkage component includes toothed grooves 13 evenly arranged on the outer wall of the tension rod 7, and the toothed grooves 13 are located above the limiting seat 18. The top of the fermentation tank 1 is symmetrically rotatably provided with a turntable 8. The outer wall of the turntable 8 is evenly provided with half-circumference teeth 14. Two teeth 14 located on the same side respectively mesh with one of the two opposing sets of toothed grooves 13. The top of the fermentation tank 1 is provided with a synchronous linkage component that drives the two turntables 8 to rotate simultaneously.

[0031] The two turntables 8 rotate simultaneously via a synchronous linkage mechanism, causing the teeth 14 on one turntable 8 to rotate half a revolution. When the teeth 14 on one turntable 8 engage with the grooves 13 on the corresponding tension rod 7, the smooth surface on the other turntable 8 is positioned opposite to the grooves 13 on the tension rod 7. At this time, the tension rod 7 engaged with the grooves 13 drives the limiting seat 18 to move, causing the limiting seat 18 to compress the elastic element 17 and generate elastic force. After the two turntables 8 rotate half a revolution again, the grooves 13 and teeth 14 on one tension rod 7 disengage, and the elastic element 17 slides upward using its elastic force. At the same time, the other tension rod 7 pushes the elastic material net 6 to move. As the two turntables 8 rotate synchronously and continuously, the two parts of the elastic material net 6 deform alternately, improving the dispersion of the raw material falling on the elastic material net 6. At the same time, vibration prevents the raw material from clogging the mesh, ensuring the smoothness of the feeding process.

[0032] In addition, the synchronous linkage component includes a bracket 19 symmetrically fixed to the top of the fermenter 1, a movable shaft 20 rotatably mounted on the bracket 19, a turntable 8 sleeved on the outside of the movable shaft 20, a driven member 21 sleeved on the outer wall of the movable shaft 20 extending out of the bracket 19, and an active member 15 rotatably mounted on the top of the fermenter 1. The active member 15 rotates synchronously with the two driven members 21 through the transmission member 16.

[0033] The diameter of the driving component 15 is larger than that of the driven component 21. Both the driving component 15 and the driven component 21 can be pulleys, and the transmission component 16 is a transmission belt. The large-diameter driving component 15 and the small-diameter driven component 21 ensure the tightness of the transmission component 16. Alternatively, the driving component 15 and the driven component 21 can be sprockets, and the transmission component 16 can be a chain. In this case, a limiting frame is installed inside the protective cover 10 to restrict the movement direction of the chain, ensuring that the driving component 15 and the driven component 21 are in the meshing position with the transmission component 16. The motor is fixed to the top of the fermenter 1 by a frame. The driving component 15 is fixedly sleeved onto the outer wall of the motor output shaft through the central mounting hole. The motor is connected to an external power source via wires.

[0034] In addition, feed inlets 11 are evenly embedded in the top of the outer wall of the fermenter 1. A plug is provided on the feed inlet 11 to ensure the sealing effect of the feed inlet 11.

[0035] Furthermore, a discharge port 12 is embedded in the bottom of the fermenter 1, and a valve is provided on the discharge port 12. The opening and closing of the discharge port 12 is controlled by the valve, and the yeast culture processed by the fermenter 1 is discharged to the outside through the discharge port 12.

[0036] A protective cover 10 is fixedly attached to the top of the fermenter 1, covering the outside of the reset tension member and the opposing linkage member. The protective cover 10 protects the components at the top of the fermenter 1 from damage.
