Description

Technical Field

[0001] This invention relates to the field of Cordyceps militaris cultivation technology, specifically to an isolated fermentation cultivation platform for the industrialized production of Cordyceps militaris strains. Background Technology

[0002] Cordyceps flower, also known as North Cordyceps, is a fungus rich in various nutrients, including protein, amino acids, cordycepin, and polysaccharides. It has extremely high nutritional and medicinal value. As people pay more attention to health, the market demand for Cordyceps flower continues to grow. Whether in the domestic or international market, the demand for high-quality Cordyceps flower is very strong. This places higher demands on the production of Cordyceps flower, requiring more efficient, stable, and high-quality production methods to meet market demand.

[0003] In the prior art, such as Chinese Patent No. CN114885756B, a device for the industrialized production and cultivation of Cordyceps militaris is disclosed, relating to the field of Cordyceps militaris production and cultivation technology. It includes a cultivation platform, a culture vessel, and atomizing water spray holes. Atomizing water spray holes are provided on the inner surfaces of both sides of the cultivation platform, and a culture vessel is provided on the outer surface of the cultivation platform. A snap-fit ​​groove is provided on the outer surface of the culture vessel, and an elastic soft block is detachably connected to the inner surface of the snap-fit ​​groove. This invention, in conjunction with a fungal culture dish, overlaps the fungal tank, and uses limiting compression strips to overlap the two sides of the fungal tank to restrict its position. During daily growth, a breathable column is used to inject oxygen into the interior of the fungal tank to promote fungal growth. This invention possesses the characteristic of spatially limiting the fungal tank, solving the problem that the fungal tank, which is directly overlapped in the culture dish, will fall off during transportation, thus achieving the effect of spatially limiting the fungal tank.

[0004] The fermentation and cultivation of Cordyceps militaris requires a sterile, isolated environment. This includes steps such as preparing the culture medium, adding the inoculum, and sealing and controlling the temperature for fermentation. When preparing the culture medium, different ingredients are sterilized by high-temperature steam in a mixing tank and stirred to ensure thorough mixing. During the inoculum addition process, a separate stirring device is required to manually mix the inoculum with the culture medium before sealing and fermentation. This means that at least two stirring mechanisms are needed in industrial-scale fermentation and cultivation: one set inside the culture medium preparation equipment and the other set operated manually. This not only increases the overall equipment platform's operating and maintenance costs but also leads to incomplete cleaning because the stirring mechanism cannot be disassembled separately, which can easily cause subsequent bacterial growth and thus affect the quality of Cordyceps militaris.

[0005] Therefore, we propose an isolated fermentation cultivation platform for the industrialized production of Cordyceps militaris strains to address the problems mentioned in the background technology. Summary of the Invention

[0006] The purpose of this invention is to provide an isolated fermentation and cultivation platform for the industrial production of Cordyceps militaris spawn, in order to solve the problem mentioned in the background art that at least two sets of stirring mechanisms are required in the industrial fermentation and cultivation of Cordyceps militaris, one set is located inside the culture medium preparation equipment and the other is manually operated. This situation not only increases the overall equipment platform's usage and maintenance costs, but also leads to incomplete cleaning because the stirring mechanism cannot be removed separately, which can easily cause subsequent bacterial growth and thus affect the quality of Cordyceps militaris.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In this invention, the stirring component in the Cordyceps militaris spawn cultivation process is redesigned, separating its power part from the stirring part. This eliminates the need for the stirring mechanism inside the culture medium mixing equipment and the stirring device used to mix the spawn and the culture medium. This significantly reduces the complexity, operating cost, and maintenance cost of the Cordyceps militaris spawn fermentation cultivation platform. Furthermore, after the Cordyceps militaris cultivation is completed, the driven stirring component can be pulled upwards for separate cleaning and sterilization. This not only reduces the difficulty of cleaning but also effectively prevents bacterial growth, thereby improving the quality of the cultivated Cordyceps militaris.

[0019] 2. When using this invention, the entire Cordyceps militaris spawn cultivation process is highly automated. From culture medium mixing, spawn introduction, environmental control to fermentation cultivation, all are completed automatically by mechanical equipment, effectively avoiding the tediousness and uncertainty of manual operation, improving production efficiency and stability. This design has the capability for large-scale production, can meet the market demand for Cordyceps militaris spawn, and has good market value and competitiveness.

[0020] 3. When using this invention, place the culture dish on the traveling plate and press it down. The bottom touches the inclined surface of the positioning block, and the flipping frame then unfolds the positioning block. During the process, the elastic ring in the annular groove applies pressure to fix the culture dish, ensuring stability. When removing it, it can be easily pulled up. After removal, the elastic ring resets the positioning block, and the limiting strip is locked by the pressure ring, which plays a role in limiting the initial angle of the positioning block. This design simplifies the disassembly and assembly process of the culture dish, improves the convenience of operation, and ensures a stable environment for the fermentation and cultivation of Cordyceps militaris.

[0021] 4. In use, the steam tank heats the water inside to generate steam, which is then used to sterilize the culture medium raw materials inside the fusion tank with high-temperature steam. The steam is then discharged through the pressure relief pipe at the top of the fusion tank and enters the spiral tube inside the heat exchange tank. Here, the high-heat steam flows along the spiral tube and exchanges heat with the room-temperature water in the heat exchange tank, effectively raising the water temperature and realizing heat recovery. Once the level gauge in the steam tank detects insufficient water, the solenoid valve on the water supply pipe responds quickly and automatically injects preheated water into the steam tank through the water supply pipe, achieving immediate water replenishment. This design greatly reduces the electrical energy required to generate steam inside the steam tank, significantly reducing the energy consumption of Cordyceps militaris fermentation and cultivation, and has the effect of energy saving and emission reduction.

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1: Please refer to Figures 1-13As shown, the present invention provides a technical solution: an isolated fermentation cultivation platform for the industrialized production of Cordyceps militaris spawn, comprising a frame assembly 1, a traveling assembly 2, a driven stirring assembly 3, a stirring power assembly 4, a first feeding assembly 5, an energy-saving auxiliary assembly 6, a second feeding assembly 7, and a sealing assembly 8.

The driven stirring assembly 3 includes a thickened bottom 301, which is fixed to the inner bottom of the petri dish 209 by friction. A first circular shell 302 is rotatably connected to the center of the thickened bottom 301 via a bearing. Inside the first circular shell 302, a first partition 303 and multiple first magnetic blocks 304 are fixed.

The circular shell 302 is fixedly connected by bolts. A stirring blade 307 is fixedly connected to the top center of the inner bottom plate 306. A stirring power assembly 4 is located at the bottom of the frame assembly 1 and is used to drive the driven stirring assembly 3 to stir the materials. A first feeding assembly 5 is located at the top of the frame assembly 1 and is used to mix the culture medium raw materials and feed them into the culture dish 209. An energy-saving auxiliary assembly 6 is located at the top of the frame assembly 1 and is used to recover steam heat to preheat water. A second feeding assembly 7 is located at the top of the frame assembly 1 and is used to feed the Cordyceps militaris spawn into the culture dish 209. A sealing assembly 8 is located at the top of the frame assembly 1 and is used to seal the culture dish 209 and monitor its status. The frame assembly 1 includes a workbench 101, and a stirring blade 307 is fixedly connected to the bottom of the workbench 101. The support frame 102 has side plates 106 symmetrically installed at the middle position near the front and rear edges of the top of the worktable 101. A first top plate 107, a second top plate 108, and a third top plate 109 are installed on the top of the two side plates 106. A threaded screw 105 is rotatably embedded at the middle position of the top of the worktable 101. A stepper motor 104 is installed on one outer surface of the worktable 101, and the output end of the stepper motor 104 is fixedly connected to one end of the threaded screw 105. A controller 103 is installed on one outer surface of the worktable 101. A traveling plate 201 is slidably installed on the top of the worktable 101, and the thread of the threaded screw 105 penetrates the outer surface of the traveling plate 201. Multiple tilting frames 202 are fixedly connected at equal intervals on the top of the traveling plate 201.A positioning block 203 is fixedly connected to the top of the flipping frame 202. The top of the positioning block 203 is inclined outward. Multiple positioning blocks 203 are radially distributed on the outside of the culture dish 209, and the inner outer surface of the positioning block 203 is in contact with the outer surface of the culture dish 209. An annular groove 205 is formed near the middle of the outer surface of the multiple positioning blocks 203. An elastic ring 206 is sleeved between the interior of the multiple annular grooves 205. An outwardly extending limiting strip 204 is fixedly connected to the bottom of the outer surface of the positioning block 203. A pressure ring 207 is provided above the limiting strip 204. Multiple connecting posts 208 are fixedly connected at equal intervals to the bottom of the pressure ring 207. The bottom of the connecting posts 208 is fixedly connected to the top of the traveling plate 201. The bottom of the pressure ring 207 and the top of the limiting strip 204 are not in contact. In the contact state, the stirring power assembly 4 includes a cover 401 and two second circular shells 402. The cover 401 is fixedly installed on the bottom of the workbench 101. Both second circular shells 402 are rotatably connected to the bottom of the workbench 101. Inside each second circular shell 402, a second partition 403 and six second magnetic blocks 404 are fixedly installed. The second partition 403 divides the interior of the second circular shell 402 into six sections to accommodate the second magnetic blocks 404. Each of the two second circular shells 402 has a pulley 405 fixedly connected to its bottom. A drive belt 406 is connected between the outer surfaces of the two pulleys 405. A servo motor 407 is fixedly installed on the bottom of the cover 401. The output end of the servo motor 407 rotates through the outer surface of the cover 401 and is fixedly connected to the center of the bottom of one of the pulleys 405.

[0038] In this embodiment, the cultivation platform is first used in a sterile isolation area, and operators must wear sterile clothing to operate it. A support frame 102 is welded to the bottom of the workbench 101 to support the entire device. The first top plate 107, second top plate 108, third top plate 109, and side plate 106 form the frame of the top of the workbench 101. The controller 103 is electrically connected to other electrical components via wiring to receive data and control the operation of these components. Inside the first circular shell 302, six first magnetic blocks 304, separated by a first partition 303, are arranged in opposite directions between each pair of adjacent first magnetic blocks 304. One adjacent end is the South Pole, and the other is the North Pole. The second magnetic block 404 inside the second circular shell 402 is arranged in the same way as the first magnetic block 304. When the first circular shell 302 and the second circular shell 402 are vertically aligned, when one set of magnetic blocks rotates, the other set of magnetic blocks will rotate synchronously due to the property that like poles of a magnetic field repel and unlike poles attract. The outer diameter of the thickened bottom 301 and the inner bottom plate 306 is the same as the inner diameter of the culture dish 209. After pressing them into the culture dish 209, the installation can be completed. The outer ring of the inner bottom plate 306 is electroplated and can rotate smoothly inside the culture dish 209.

[0039] When in use, place the culture dish 209 on top of the traveling plate 201 and press it down. The bottom of the culture dish 209 will be squeezed against the top slope of the positioning block 203. Under the action of the flipping frame 202, the left and right positioning blocks 203 will be pushed outward. During the pushing process, the elastic ring 206 inside the annular groove 205 will exert a squeezing force on the positioning block 203, thereby squeezing and fixing the culture dish 209 through the positioning block 203, so that it maintains sufficient stability during use. When taking it out, simply pull it upward. After the culture dish 209 is removed, the positioning block 203 will continue to flip inward at a certain angle under the action of the elastic ring 206. Then the limiting strip 204 that moves with the positioning block 203 will be pressed by the pressure ring 207, thereby limiting the initial angle of the positioning block 203. This design allows the culture dish 209 to maintain sufficient stability during the fermentation and cultivation of Cordyceps militaris, and it is simple and practical to disassemble and assemble, with high operation convenience.

[0040] After the culture dish 209 is fixed, the stepper motor 104 is started, driving the threaded screw 105 to rotate, which in turn drives the traveling plate 201 to move below the first feeding component 5 to receive the prepared culture medium raw materials. At this time, the servo motor 407 under the workbench 101 is started. After the servo motor 407 is started, it drives the second circular shell 402 located directly below the first feeding component 5 to rotate through the pulley 405 at the drive end. At this time, the specially designed second magnetic block 404 inside the second circular shell 402 uses the magnetic field characteristics to drive the first magnetic block 304 inside the first circular shell 302 to rotate rapidly. And through the first circular cover 305 and the inner bottom plate 306, the stirring blade 307 starts to rotate rapidly at the bottom of the culture medium, thereby making the different ingredients of the culture medium evenly mixed. Then, the stepper motor 104 and the threaded screw 105 cooperate to drive the traveling plate 201 to move the culture dish 209 containing the culture medium to below the second feeding component 7. A fixed amount of Cordyceps militaris spawn is fed into the culture dish 209 by the second feeding component 7 and mixed with the culture medium. At this time, the servo motor 407 is started to drive the pulley 405 above to rotate at low speed. Under the action of the transmission belt 406, the rotational force is transmitted to the pulley 405 located directly below the second feeding component 7. The pulley 405 drives the second circular shell 402 and the second magnetic block 404 at the top to rotate at low speed. During the process, the driven stirring component 3 in the culture dish 209 is used to achieve full mixing of the culture medium and the Cordyceps militaris spawn. This design separates the power part and the stirring part in the transmission stirring component, eliminating the stirring mechanism inside the culture medium mixing equipment and the stirring device for mixing the spawn and the culture medium. This reduces the use cost and maintenance cost of the Cordyceps militaris spawn fermentation and cultivation platform. Furthermore, after the Cordyceps militaris cultivation is completed, the driven stirring component 3 can be pulled upwards for separate cleaning and sterilization, reducing the cleaning difficulty, avoiding bacterial growth, and thus improving the quality of the cultivated Cordyceps militaris.

The top of the gas diffuser shell 507 and the bottom of the fusion tank 502 are fixedly connected. The energy-saving auxiliary component 6 includes an annular frame 601 and a water storage tank 607. Both the annular frame 601 and the water storage tank 607 are installed near the edge of the top of the first top plate 107. The inner wall of the annular frame 601...

An exhaust pipe 605 is fixedly connected to the bottom of the heat exchange tank 602, and the top end of the exhaust pipe 605 is connected to the bottom end of the spiral tube 603. The outer surface of the heat exchange tank 602 is close to the lower... The water supply pipe 606 with an external solenoid valve is fixedly connected to the position of the water tank 607, and the outer end of the water supply pipe 606 is fixedly connected to the steam tank 505. A water supply pump 608 is fixedly installed on the top of the water storage tank 607 by a bracket. The input end of the water supply pump 608 is fixedly connected to the water pump pipe 609, and the output end of the water supply pump 608 is fixedly connected to the water delivery pipe 610. The outer end of the water pump pipe 609 extends into the interior of the water storage tank 607, and the outer end of the water delivery pipe 610 is fixedly connected to the heat exchange tank 602.

[0042] In this embodiment, firstly, the steam tank 505 is equipped with a liquid level sensor and a heating element to heat the water inside to form steam. The gas supply pipe 506 is mainly used to input steam into the fusion tank 502 for high-temperature steam sterilization of the culture medium ingredients. An electromagnetic valve is installed on the outside of the gas supply pipe 506 to control the steam delivery. The feed pipe 503 at the top of the fusion tank 502 is equipped with a metering pump, mainly used to proportionally supply glucose, sucrose, peptone, yeast extract, potassium dihydrogen phosphate, and magnesium sulfate from the culture medium raw materials into the fusion tank 502. The top of the gas diffuser shell 507 has a large number of gas distribution holes to connect the inside of the fusion tank 502 and the gas supply pipe 506. The discharge pipe 508 at its center is mainly used to connect the inside and outside of the fusion tank 502 for discharge. The outside is equipped with a solenoid valve for controlling opening and closing. The heat exchange tank 602 is equipped with a liquid level sensor to detect the internal water volume. The ring frame 601 is mainly used to support and raise the heat exchange tank 602, so that it forms a height difference with the steam tank 505. Then, the water pressure is used to eliminate the water pump between the steam tank 505 and the heat exchange tank 602, reducing the cost of the platform equipment.

[0043] During use, after the culture dish 209 is moved directly below the fusion tank 502, glucose, sucrose, peptone, yeast extract, potassium dihydrogen phosphate, and magnesium sulfate are fed through the feed pipe 503. During this process, the steam tank 505 heats the water inside to generate steam, which is then introduced into the fusion tank 502 from below through the gas supply pipe 506 and the gas diffuser 507 to sterilize the culture medium raw materials with high-temperature steam. After sterilization, the steam is discharged from the pressure relief pipe 504 at the top of the fusion tank 502 and then enters the spiral tube 603 inside the heat exchange tank 602 through the return gas pipe 604. At this point, the steam with residual high heat passes through the spiral tube 603 and is discharged to the outside through the exhaust pipe 605. During this process, heat exchange occurs between the steam and the room-temperature water inside the heat exchange tank 602, thus oxidizing the water inside the heat exchange tank 602. As the temperature rises, when the level gauge inside the steam tank 505 detects insufficient water, the solenoid valve outside the water supply pipe 606 will be activated in time, and heated water will be introduced into the steam tank 505 through the water supply pipe 606 to replenish the water. When the heater inside the steam tank 505 heats the heated water to generate steam, it can save a lot of electricity. This design reduces the energy consumption in the Cordyceps militaris fermentation process, further controls costs, and has the effect of energy saving and emission reduction. After the water in the heat exchange tank 602 is introduced into the steam tank 505, the internal level sensor will convert the liquid level height into an electrical signal and send it to the water supply pump 608. At this time, the water supply pump 608 will draw water from the water storage tank 607 through the water pumping pipe 609 and replenish it into the heat exchange tank 602 through the water delivery pipe 610, thus forming a cycle.

[0044] Example 3: Figures 1-3 and Figures 10-13As shown, the second feeding assembly 7 includes a transfer tank 701, which is fixedly installed on the top of the second top plate 108. A first electric actuator 702 is installed on the top of the transfer tank 701, and the telescopic end of the first electric actuator 702 slides through the top of the transfer tank 701 and extends downward. A piston 703 is fixedly connected to the telescopic end of the first electric actuator 702, and the outer surface of the piston 703 is in contact with the inner wall of the transfer tank 701.

An L-shaped feeding pipe 706 is fixedly connected to the bottom of the transfer tank 701. The feeding pipe 706 penetrates the second top plate 108 and extends downwards. Multiple branch pipes 707 are fixedly connected to the bottom of the feeding pipe 706, with the lengths of the branch pipes 707 decreasing sequentially from the inside out. A rotating seat 708 is fixedly connected to the bottom of the feeding pipe 706. A second electric actuator 709 is rotatably connected between the inner walls of the rotating seat 708. One of the branch pipes 707... Two T-shaped brackets 710 are symmetrically fixedly connected to the outer surface of the 07. A closing plate 711 is rotatably connected between the outer surfaces of the two T-shaped brackets 710 near the lower part. The telescopic end of the second electric push rod 709 is rotatably connected to one end of the closing plate 711. The outer surface of the closing plate 711 is tightly fitted to the bottom of the multiple branch pipes 707. The sealing assembly 8 includes a third electric push rod 801, which is fixedly installed on the top of the third top plate 109 and extends downward after its telescopic end passes through the top of the third top plate 109. The telescopic end of the third electric actuator 801 is fixedly connected to a sealing plate 802. The sealing plate 802 is used to compress and seal the culture dish 209. A monitoring sensor 803, a temperature regulating device 804, and an acid-base tank 805 are fixedly installed on the top of the sealing plate 802. The detection end of the monitoring sensor 803 passes through the sealing plate 802 and extends downward. The discharge port of the acid-base tank 805 passes through the sealing plate 802 and extends downward. The top of the acid-base tank 805 is fixedly connected to a feeding pipe 806 that passes through the third top plate 109 and extends upward.

[0045] In this embodiment, firstly, a specified amount of Cordyceps militaris inoculum can be delivered into the transfer tank 701 through the feed pipe 705 in conjunction with an external metering pump. The total specific gravity of the Cordyceps militaris inoculum is 5% to 10% of the culture medium, depending on the actual situation. The first electric actuator 702 is mainly used to push the piston 703 inside the transfer tank 701 to move up and down. The air inlet valve 704 is a one-way valve that only allows air to enter the transfer tank 701. The opening and closing plate 711 is used to seal the bottom of all branch pipes 707. The feed pipe 806 is mainly used to replenish the acid and alkali solvents inside the acid and alkali tank 805. The monitoring sensor 803 consists of a temperature sensor and a pH sensor.

[0046] In use, a specified amount of Cordyceps militaris spawn is fed into the transfer tank 701 through the feed pipe 705. Under gravity, the spawn flows through the feed pipe 706 into all the branch pipes 707, filling them completely. When the culture dish 209 containing the culture medium reaches below the feed pipe 706 and is slowly rotating, the second electric actuator 709 retracts. At this time, the upper end of the second electric actuator 709 rotates via the rotating seat 708, and the lower end rotates with the opening and closing plate 711. The opening and closing plate 711 rotates around the connection point of the T-shaped frame 710, moving away from below all the branch pipes 707. The spawn in the branch pipes 707 then enters the rotating culture dish 209. The length of the branch pipes 707 near the center of the culture dish 209 decreases sequentially, thus increasing the spawn capacity of each branch pipe 707. The microorganisms in the culture dish 209 and the inner branch tube 707 decrease sequentially, and the circumferential path formed by the rotation of the culture dish 209 and the inner branch tube 707 also decreases synchronously. Therefore, the microorganisms in the branch tube 707 are more evenly distributed in the culture medium, which improves the uniformity of microorganism distribution. This design structure is reasonable and avoids excessive concentration of microorganisms in the culture medium, which would lead to unsatisfactory cultivation results. At the same time, during the process of adding microorganisms, the second electric push rod 709 is activated to drive the piston 703 to move up and down. When the piston 703 moves upward, outside air enters the transfer tank 701 through the air inlet valve 704. When the piston 703 moves downward, the air inside the transfer tank 701 is discharged downward from the branch tube 707. Under the action of airflow, the microorganisms inside the transfer tank 701 can be fully discharged into the culture dish 209, avoiding residues that would affect the proportion of microorganisms and ensuring the cultivation effect of Cordyceps militaris microorganisms.

[0047] After the inoculum is added, the stepper motor 104 and the threaded screw 105 drive the culture dish 209 to the bottom of the sealing assembly 8. Then, the third electric actuator 801 is activated, causing the sealing plate 802 to press against the top opening of the culture dish 209, thus achieving a seal. At this time, the monitoring sensor 803 monitors the temperature and pH value inside the culture dish 209 in real time, and the temperature is adjusted in real time by the temperature regulating device 804. Acid and alkali solvents are added to the culture dish 209 through the acid-alkali container 805 for real-time adjustment, thereby ensuring the culture is in a stable and healthy state. The temperature of the substrate is controlled between 20℃ and 25℃, and the pH value is controlled within the range of 5.5-7.0 to meet the growth requirements of Cordyceps militaris. After the fermentation is completed, the culture dish 209 is moved out from under the third top plate 109 and removed by the stepper motor 104 and the threaded screw 105. The cultivation platform has a reasonable structure and a high degree of automation, which effectively avoids the problems of time-consuming and labor-intensive manual participation in the fermentation of Cordyceps militaris, unstable production quality, and difficulty in large-scale production. It has good market value and market competitiveness.

[0048] The overall effect and working principle of this mechanism are as follows: This culture station is used in a sterile isolation area. Operators must wear sterile clothing. When using it, place the culture dish 209 on top of the travel plate 201 and press down. The bottom of the culture dish 209 will press against the top inclined surface of the positioning block 203. Under the action of the flipping frame 202, the left and right positioning blocks 203 will be pushed outwards. During the pushing process, the elastic ring 206 inside the annular groove 205 will exert a compressive force on the positioning block 203, thereby fixing the culture dish 209 by the positioning block 203, ensuring sufficient stability during use. To remove it, simply pull it upwards. After the culture dish 209 is removed, the positioning block 203 will continue to flip inwards at a certain angle under the action of the elastic ring 206. The limiting strip 204, which moves with the positioning block 203, is pressed down by the pressure ring 207, thus limiting the initial angle of the positioning block 203. This design allows the culture dish 209 to maintain sufficient stability during the fermentation and cultivation of Cordyceps militaris, and it is simple and practical to assemble and disassemble. After the culture dish 209 is fixed, the stepper motor 104 is started to drive the threaded screw 105 to rotate, which in turn drives the traveling plate 201 to move below the first feeding component 5 to receive the proportioned culture medium raw materials. At this time, the servo motor 407 below the workbench 101 is started. After the servo motor 407 is started, it will drive the second circular shell 402 located directly below the first feeding component 5 to rotate through the pulley 405 at the drive end. At this time, the specially designed second magnet inside the second circular shell 402 is activated. The force block 404 utilizes the magnetic field properties to drive the first magnetic block 304 inside the first circular shell 302 to rotate rapidly. This, in turn, drives the stirring blade 307 to rotate rapidly at the bottom of the culture medium via the first circular cover 305 and the inner bottom plate 306, ensuring uniform mixing of the different ingredients. Then, the stepper motor 104 and the threaded screw 105 work together to drive the traveling plate 201, moving the culture dish 209 containing the culture medium below the second feeding component 7. The second feeding component 7 then dispenses a fixed amount of Cordyceps militaris inoculum into the culture dish 209 to mix with the culture medium. At this point, the servo motor 407 is activated, driving the upper pulley 405 to rotate at low speed. The rotational force is transmitted to the second feeding component 7 via the transmission belt 406. The pulley 405 directly below drives the second circular shell 402 and the second magnetic block 404 at the top to rotate at a low speed. During this process, it works in conjunction with the driven stirring component 3 in the petri dish 209 to achieve thorough mixing of the culture medium and the Cordyceps militaris spawn. This design separates the power and stirring parts of the transmission stirring component, eliminating the need for the stirring mechanism inside the culture medium mixing equipment and the stirring device used to mix the spawn and the culture medium. This reduces the operating and maintenance costs of the Cordyceps militaris spawn fermentation platform. Furthermore, after the Cordyceps militaris cultivation is completed, the driven stirring component 3 can be pulled upwards for separate cleaning and sterilization, reducing cleaning difficulty, preventing bacterial growth, and thus improving the quality of the cultivated Cordyceps militaris. When the petri dish 209 is moved directly below the fusion tank 502...Glucose, sucrose, peptone, yeast extract, potassium dihydrogen phosphate, and magnesium sulfate are fed through feed pipe 503. During this process, steam tank 505 heats the water inside to generate steam, which is then introduced from below into fusion tank 502 through gas delivery pipe 506 and gas diffuser 507 to sterilize the culture medium raw materials with high-temperature steam. After sterilization, the steam is discharged from the pressure relief pipe 504 at the top of fusion tank 502 and then enters the spiral tube 603 inside heat exchange tank 602 through return gas pipe 604. At this time, the steam with residual high heat passes through spiral tube 603 and is discharged to the outside through exhaust pipe 605. During this process, heat exchange occurs with the room temperature water inside heat exchange tank 602, causing the water temperature inside heat exchange tank 602 to rise. When steam tank 505... When the internal level gauge of tank 05 detects insufficient water, the solenoid valve outside the water supply pipe 606 will be activated in time, and heated water will be introduced into the steam tank 505 through the water supply pipe 606 to replenish the water. The heater inside the steam tank 505 heats the heated water to generate steam, which can save a lot of electricity. This design reduces the energy consumption in the Cordyceps militaris fermentation process, further controls costs, and has the effect of energy saving and emission reduction. Subsequently, a specified amount of Cordyceps militaris inoculum is introduced into the transfer tank 701 through the feed pipe 705. At this time, under the action of gravity, the inoculum will enter all the branch pipes 707 through the feed pipe 706 and fill the branch pipes 707. When the culture dish 209 containing the culture medium reaches below the feed pipe 706 and slowly enters the transfer tank 701, the inoculum will be introduced into the transfer tank 701. When rotating, the second electric actuator 709 retracts. At this time, the upper end of the second electric actuator 709 rotates via the rotating seat 708, and the lower end rotates with the opening / closing plate 711. The opening / closing plate 711 rotates around the connection point of the T-shaped frame 710, thus moving away from below all the branch tubes 707. The bacteria in the branch tubes 707 then enter the rotating culture dish 209. The length of the branch tubes 707 near the center of the culture dish 209 decreases sequentially, thus decreasing the amount of bacteria they can hold. The circumferential path formed by the rotating culture dish 209 and the inner branch tubes 707 also decreases synchronously, resulting in a more even distribution of bacteria in the culture medium and improving the uniformity of bacterial distribution. This design... The structure is reasonable, avoiding excessive concentration of microorganisms in the culture medium, which could lead to unsatisfactory cultivation results. During the addition of microorganisms, the second electric actuator 709 is activated, driving the piston 703 up and down. When the piston 703 moves upward, outside air enters the transfer tank 701 through the air inlet valve 704. When the piston 703 moves downward, the air inside the transfer tank 701 is discharged downward through the branch pipe 707. This airflow ensures that the microorganisms inside the transfer tank 701 are fully discharged into the culture dish 209, preventing residue from affecting the microorganism ratio and ensuring the cultivation effect of the Cordyceps militaris. After the microorganisms are added, the stepper motor 104 and the threaded screw 105 drive the culture dish 209 below the sealing assembly 8.Subsequently, the third electric actuator 801 is activated, causing the sealing plate 802 to press down on the top opening of the culture dish 209, thus achieving a seal. At this time, the monitoring sensor 803 monitors the temperature and pH value inside the culture dish 209 in real time, and the temperature in the culture dish 209 is adjusted in real time via the temperature regulation device 804. Acid and alkali solvents are added to the culture dish 209 via the acid-alkali tank 805 for real-time adjustment, thereby controlling the temperature of the culture medium between 20℃ and 25℃ and the pH value within the range of 5.5-7.0, meeting the growth requirements of the Cordyceps militaris spawn. After fermentation, the culture dish 209 is moved from below the third top plate 109 and removed by the stepper motor 104 and the threaded screw 105, completing the process. This cultivation platform has a reasonable structure and a high degree of automation, effectively avoiding the time-consuming and labor-intensive nature of manual Cordyceps militaris spawn fermentation, the unstable production quality, and the difficulty in large-scale production. It possesses good market value and competitiveness.
