Technical Field

[0001] The present invention relates to the technical field of fermentation equipment, and in particular to a fermentation tank with constant temperature and humidity. Background Art

[0002] Fermentation refers to the process of using microorganisms to produce specific products. Under specific conditions, microorganisms convert organic substances into more valuable or more easily utilizable products. This process is not limited to anaerobic conditions but also includes the metabolic activities of microorganisms under aerobic conditions. A fermentation tank is a container that provides a good environment for the operation of a specific biochemical process of microorganisms and is the most important and widely used equipment in fermentation equipment. Its core function is to provide a suitable growth and fermentation environment for microorganisms or enzymes. By controlling the fermentation conditions, it promotes the growth and metabolism of microorganisms, thereby producing the required products. Whether it is amino acids, organic acids, antibiotics, vitamins, etc., the fermentation tank is the key production equipment for these key fermentation products.

[0003] In the existing fermentation tank, the materials inside are piled up together during fermentation, which easily causes incomplete fermentation of the materials, resulting in uneven fermentation, and it is also impossible to ensure that the materials are in a constant temperature and humidity environment, affecting the fermentation effect. Therefore, a fermentation tank with constant temperature and humidity is proposed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that in the existing fermentation tank, the materials inside are piled up together during fermentation, which easily causes incomplete fermentation of the materials, resulting in uneven fermentation, and it is also impossible to ensure that the materials are in a constant temperature and humidity environment, affecting the fermentation effect. The present invention provides a fermentation tank with constant temperature and humidity.

[0005] The technical solution adopted by the present invention to solve its technical problems is: A fermentation tank with constant temperature and humidity, comprising a main body, a stirring and fermenting mechanism, a temperature self-regulating mechanism, and a humidity synchronous control mechanism; A number of mounting brackets are fixedly arranged in the middle of the outer side wall of the main body. A feeding port is opened on the left side of the top of the main body. The input end of the feeding port is connected to a feeding machine through a pipeline. A driving motor is arranged at the top right of the main body. The driving motor is fixedly connected to the top of the main body through a connecting block. The stirring and fermenting mechanism is arranged in the middle of the inner side of the main body. The temperature self-regulating mechanism is arranged in the middle of the stirring and fermenting mechanism. The humidity synchronous control mechanism is arranged on the upper part of the inner side wall of the main body. A fixing rod is fixedly arranged between the bottom side walls of adjacent mounting brackets. A base is fixedly arranged at the bottom of the mounting bracket. When in use, materials are added into the main body through the feeding port, and then the driving motor is started. The materials are stirred through the operation of the stirring and fermenting mechanism, avoiding uneven reaction during fermentation and incomplete fermentation, improving the fermentation effect. During fermentation, the fermentation temperature is controlled through the temperature self-regulating structure, avoiding the influence of too high or too low temperature on the fermentation effect. When the stirring and fermenting mechanism operates, it drives the humidity synchronous control mechanism to continuously dehumidify the fermentation tank synchronously, avoiding too high humidity inside the fermentation tank.

[0006] Further, the stirring and fermenting mechanism includes a rotating shaft. The rotating shaft is arranged at the output end of the driving motor. The center of the top of the main body is fixedly provided with a gear box. The other end of the rotating shaft extends into the interior of the gear box. The other end of the rotating shaft is connected with a driving bevel gear. The rotating shaft is perpendicular to the left side wall of the gear box. The upper driven bevel gear is meshed with the top edge of the driving bevel gear. The center of the upper driven bevel gear is connected with an inner sleeve. The top of the inner sleeve extends to the outside of the top of the gear box. The lower driven bevel gear is meshed with the bottom edge of the driving bevel gear. The bottom center of the lower driven bevel gear is connected with an outer sleeve. The bottom of the inner sleeve passes through the lower driven bevel gear and extends to the inner bottom of the main body. The outer sleeve is rotatably sleeved on the outer side wall of the inner sleeve. The outer sleeve and the inner sleeve are coaxially arranged. The inner sleeve is perpendicular to the top of the main body. When the driving motor operates, the driving bevel gear is driven to rotate through the rotating shaft, so that the engaged upper driven bevel gear and lower driven bevel gear start to rotate in opposite directions. When the upper driven bevel gear and the lower driven bevel gear rotate, they drive the outer sleeve and the inner sleeve to start rotating in opposite directions.

[0007] Further, the bottom of the main body is funnel-shaped, a discharge tube is arranged at the center of the bottom of the main body, the bottom end of the inner sleeve extends into the interior of the discharge tube, the bottom end of the outer sleeve extends to the middle of the outer side wall of the inner sleeve, several cross bars are evenly arranged on the outer side wall of the middle part of the inner sleeve, the cross bars are perpendicular to the inner sleeve, vertical bars are fixedly arranged at the outer ends of the cross bars, the vertical bars are parallel to the inner sleeve, several first stirring rods are evenly arranged on the side wall of the vertical bar facing the inner sleeve, several second stirring rods are evenly arranged on the outer side wall of the outer sleeve, and the first stirring rods and the second stirring rods are arranged in a staggered manner. When the outer sleeve rotates, it drives the second stirring rods to start rotating. When the inner sleeve rotates, it drives the cross bars and the vertical bars to start rotating in the opposite direction to the outer sleeve. When the vertical bars rotate, they drive the first stirring rods to start rotating, so that the first stirring rods and the second stirring rods rotate towards each other, fully stirring the materials inside the main body and improving the fermentation effect.

[0008] Further, a spiral blade is fixedly arranged on the outer side wall of the bottom of the inner sleeve, the diameter of the spiral blade matches the inner diameter of the discharge tube, the bottom end of the spiral blade extends to the outside of the bottom end of the inner sleeve, a discharge valve is fixedly arranged at the bottom of the discharge tube, and the bottom output end of the discharge valve is connected to a receiving tank through a pipeline. When the inner sleeve rotates, it drives the spiral blade at the bottom to start rotating. When the spiral blade rotates, it drives the materials at the bottom of the main body to move upward, thereby fully turning and stirring the materials inside the main body, avoiding uneven reaction during fermentation and incomplete fermentation, and further improving the fermentation effect.

[0009] Further, the temperature self-regulating mechanism includes a hot air blower, the hot air blower is fixedly arranged on the left side of the top of the main body, an inner hole is formed inside the inner sleeve, the output end of the hot air blower is connected to an air outlet pipe through a pipeline, the other end of the air outlet pipe is rotatably connected to the top end of the inner sleeve, the output end of the air outlet pipe is connected to the input end of the inner hole through a pipeline, the bottom end of the inner hole penetrates through the cross bars and the vertical bars, a flow dividing cavity is formed inside the first stirring rod, the inner hole is communicated with the flow dividing cavity, several spray holes are evenly arranged on the outer side wall of the first stirring rod, a one-way valve is arranged at the output end of the spray hole, an air outlet is formed in the top of the inner side wall of the main body, and a filter screen is fixedly arranged outside the air outlet. When the first stirring rod rotates, it drives the spray holes on its outer side wall to rotate accordingly. At this time, the hot air blower passes hot air flow into the interior of the inner sleeve through the air inlet pipe. The hot air flow flows into the cross bars and the vertical bars along the inner hole, and finally enters the flow dividing cavity inside the first stirring rod and is sprayed out through the spray holes to heat the materials. The rotation of the first stirring rod can drive the spray holes to evenly heat the materials inside the main body, and the one-way valve can prevent the materials from flowing into the interior of the flow dividing cavity.

[0010] Further, an adjustment cylinder is fixedly arranged in the middle of the inner sleeve. The inner hole vertically penetrates through the center of the adjustment cylinder. A pair of sliding rails are fixedly arranged on the outer side of the inner hole. The pair of sliding rails are arranged in parallel. A pair of baffles are slidably arranged between the sliding rails. The baffles are arranged perpendicular to the axis of the inner sleeve. The baffles are rectangular. The length of the baffle is greater than the diameter of the inner hole. The width of the baffle is greater than the radius of the inner hole. Two groups of sliding grooves are arranged in the middle of the upper surface of the baffle. The sliding grooves are arranged perpendicular to the orientation of the sliding rails. Sliders are slidably arranged inside the sliding grooves. The tops of the sliders are rotatably connected with connecting rods. Adjacent connecting rods are arranged in parallel. The facing connecting rods are symmetrically arranged.

[0011] Further, the other ends of the connecting rods are rotatably connected to the bottom of the adjustment cylinder. An adjustment rod is fixedly arranged at the end of the outer connecting rod. The adjustment rod is perpendicular to the outer connecting rod. The other end of the adjustment rod is rotatably connected with a hydraulic rod. The hydraulic rod is filled with a thermosensitive liquid. The other end of the hydraulic rod is fixedly connected to the inner wall of the adjustment cylinder. A heat conduction cavity is arranged on the outer wall at the connection between the adjustment cylinder and the hydraulic rod. The heat conduction cavity is communicated with the inner cavity of the hydraulic rod. A spring is arranged around the outside of the hydraulic rod. A pair of incomplete gears are meshingly arranged between the other ends of the facing inner connecting rods. When the temperature inside the main body is too high, the thermosensitive liquid inside the hydraulic rod expands due to heat, causing the hydraulic rod to elongate and the spring to stretch, generating a pulling force in the opposite direction, driving the adjustment rod to rotate towards the direction of the inner hole. When the adjustment rod moves, it drives the connecting rod connected to it to rotate towards the inner hole, thereby driving the baffle connected to the other end of the connecting rod through the slider to move towards the center of the inner hole along the sliding rail. When the baffle moves, it drives the inner connecting rod on its inner side to rotate accordingly, causing the incomplete gear at the bottom of the inner connecting rod to start rotating. When the incomplete gear rotates, it drives the other incomplete gear meshing with it to rotate towards each other, thereby driving the other baffle to move towards the center of the inner hole synchronously, reducing the flow area of the inner hole, thereby reducing the flow rate of the hot air flow and lowering the temperature of the material. On the contrary, when the temperature inside the main body is relatively low, the hydraulic rod moves in the opposite direction under the pulling force of the spring, driving the baffle to move towards both sides of the sliding rail, increasing the flow area of the inner hole, increasing the flow rate of the hot air flow, and raising the temperature of the material, thereby realizing the control of the fermentation temperature and avoiding the influence of too high or too low temperature on the fermentation effect.

[0012] Furthermore, the humidity synchronization control mechanism includes a dehumidification chamber fixedly arranged at the top of the inner sidewall of the main body. A one-way permeable membrane is arranged at the lower side of one sidewall of the dehumidification chamber facing the outer sleeve. A filter plate is fixedly arranged at the inner bottom of the dehumidification chamber, and a sponge is arranged on the top of the filter plate. During fermentation, the material is evenly heated by the rotation of the spray holes to ensure that the material is at a constant temperature during heating. When the material ferments, water vapor is generated. The sponge can absorb the excess water vapor inside the main body through the one-way permeable membrane to keep the humidity inside the main body constant and avoid excessive humidity inside the fermentation tank.

[0013] Furthermore, a pressing plate is movably arranged on the top of the sponge. An inclined block is fixedly arranged on the top of the pressing plate. The top of the inclined block is inclined. The bottommost end of the top of the inclined block faces the rotation direction of the vertical rod. A top rod is fixedly arranged at the top end of the vertical rod. A rotating rod is fixedly arranged on the side of the top end of the top rod facing the inner sidewall of the main body. The other end of the rotating rod extends to the top of the dehumidification chamber. A roller is rotatably arranged at the bottom of the other end of the rotating rod. The bottom height of the roller matches the bottommost height of the top of the inclined block. When the vertical rod rotates, it drives the top rod at its top to start rotating, causing the rotating rod to rotate accordingly. When the rotating rod rotates, it drives the roller to start rotating. When the roller moves to contact the top of the inclined block, the inclined block moves downward under the downward pressure, causing the pressing plate to move downward. When the pressing plate moves downward, it squeezes the sponge, thereby squeezing out the water in the sponge and realizing the continuous absorption of water vapor.

[0014] Furthermore, a liquid outlet is formed at the bottom of the dehumidification chamber. A liquid storage tank is fixedly arranged on the outer sidewall of the main body. An inclined hole is connected by a pipeline between the liquid outlet and the liquid storage tank. The water in the sponge flows out along the liquid outlet and finally flows into the inside of the liquid storage tank along the inclined hole, thereby realizing the centralized collection of water for convenient treatment.

[0015] Advantages of the present invention: 1. For the constant temperature and humidity fermentation tank of the present invention, the material is stirred through the operation of the stirring fermentation mechanism to avoid incomplete fermentation caused by uneven reaction of the material during fermentation, improving the fermentation effect. During fermentation, the fermentation temperature is controlled through the temperature self-adjusting structure to avoid the influence of too high or too low temperature on the fermentation effect. When the stirring fermentation mechanism operates, it drives the humidity synchronization control mechanism to continuously and synchronously dehumidify the inside of the fermentation tank to avoid excessive humidity inside the fermentation tank.

[0016] 2. The constant temperature and humidity fermentation tank of the present invention is provided with a stirring and fermenting mechanism. When the outer sleeve rotates, the second stirring rod starts to rotate. When the inner sleeve rotates, the cross bar and the vertical bar start to rotate in the direction opposite to that of the outer sleeve. When the vertical bar rotates, the first stirring rod starts to rotate, so that the first stirring rod and the second stirring rod rotate towards each other, fully stirring the materials inside the main body, improving the fermentation effect. When the inner sleeve rotates, the spiral blades at the bottom start to rotate. When the spiral blades rotate, the materials at the bottom of the main body move upward, thereby fully turning and stirring the materials inside the main body, avoiding incomplete fermentation caused by uneven reaction of the materials during fermentation, and further improving the fermentation effect.

[0017] 3. The constant temperature and humidity fermentation tank of the present invention is provided with a temperature self-regulating mechanism. When the temperature inside the main body is too high, the thermosensitive liquid inside the hydraulic rod expands due to heat, causing the hydraulic rod to extend, stretching the spring, generating a pulling force in the opposite direction, driving the adjusting rod to rotate towards the inner hole. When the adjusting rod moves, the connecting rod connected to it rotates towards the inner hole, thereby driving the baffle connected to the other end of the connecting rod through the slider to move towards the center of the inner hole along the slide rail. When the baffle moves, the connecting rod on its inner side rotates accordingly, causing the residual gear at the bottom of the inner connecting rod to start rotating. When the residual gear rotates, the other residual gear meshing with it rotates towards each other, thereby driving the baffle on the other side to move synchronously towards the center of the inner hole, reducing the flow area of the inner hole, thereby reducing the flow rate of the hot air flow and lowering the temperature of the materials. On the contrary, when the temperature inside the main body is relatively low, the hydraulic rod moves in the opposite direction under the pulling force of the spring, driving the baffle to move towards both sides of the slide rail, increasing the flow area of the inner hole, increasing the flow rate of the hot air flow, and raising the temperature of the materials, thereby realizing the control of the fermentation temperature and avoiding the influence of too high or too low temperature on the fermentation effect.

[0018] 4. The constant temperature and humidity fermentation tank of the present invention is provided with a humidity synchronous control mechanism. During fermentation, the materials can be evenly heated by the rotation of the spray holes, ensuring that the materials are in a constant temperature state during heating. When the materials ferment, water vapor is generated. The sponge can absorb the excess water vapor inside the main body through the one-way permeable membrane, keeping the humidity inside the main body constant and avoiding too high humidity inside the fermentation tank. When the vertical rod rotates, the top rod at its top starts to rotate, causing the rotating rod to rotate accordingly. When the rotating rod rotates, the roller starts to rotate. When the roller moves to contact the top of the inclined block, the inclined block moves downward under the downward pressure, causing the pressing plate to move downward. When the pressing plate moves downward, it squeezes the sponge, thereby squeezing out the water in the sponge and realizing the continuous absorption of water vapor.

A feeding port 5 is opened on the left side of the top of the main body 1. The input end of the feeding port 5 is connected to a feeding machine through a pipeline. A driving motor 7 is arranged on the top right side of the main body 1. The driving motor 7 is fixedly connected to the top of the main body 1 through a connecting block. The stirring and fermenting mechanism is arranged in the middle of the inner side of the main body 1. The temperature self-regulating mechanism is arranged in the middle of the stirring and fermenting mechanism. The humidity synchronous control mechanism is arranged on the upper part of the inner side wall of the main body 1. A fixing rod 3 is fixedly arranged between the bottom side walls of adjacent mounting brackets 2. The bottom of the mounting bracket 2 is fixedly provided with a base 4. When in use, materials are added into the main body 1 through the feeding port 5, and then the driving motor 7 is started. The materials are stirred through the operation of the stirring and fermenting mechanism, so as to avoid uneven reaction of the materials during fermentation, resulting in incomplete fermentation and improve the fermentation effect. During fermentation, the fermentation temperature is controlled through the temperature self-regulating structure to avoid the influence of too high or too low temperature on the fermentation effect. When the stirring and fermenting mechanism operates, it drives the humidity synchronous control mechanism to continuously and synchronously dehumidify the fermentation tank to avoid too high humidity inside the fermentation tank.

[0023] The stirring and fermenting mechanism includes a rotating shaft 29. The rotating shaft 29 is arranged at the output end of the driving motor 7. The center of the top of the main body 1 is fixedly provided with a gear box 9. The other end of the rotating shaft 29 extends into the interior of the gear box 9. The other end of the rotating shaft 29 is connected with a driving bevel gear 30. The rotating shaft 29 is vertically arranged with the left side wall of the gear box 9. The top edge of the driving bevel gear 30 is meshed with an upper driven bevel gear 31. The center of the upper driven bevel gear 31 is connected with an inner sleeve 13. The top of the inner sleeve 13 extends to the outside of the top of the gear box 9. The bottom edge of the driving bevel gear 30 is meshed with a lower driven bevel gear 32. The bottom center of the lower driven bevel gear 32 is connected with an outer sleeve 12. The bottom of the inner sleeve 13 penetrates through the lower driven bevel gear 32 and extends to the inner bottom of the main body 1. The outer sleeve 12 is rotatably sleeved on the outer side wall of the inner sleeve 13. The outer sleeve 12 and the inner sleeve 13 are coaxially arranged. The inner sleeve 13 is vertically arranged with the top of the main body 1. When the driving motor 7 operates, the driving bevel gear 30 is driven to rotate through the rotating shaft 29, so that the engaged upper driven bevel gear 31 and lower driven bevel gear 32 start to rotate in opposite directions. When the upper driven bevel gear 31 and the lower driven bevel gear 32 rotate, they drive the outer sleeve 12 and the inner sleeve 13 to start rotating in opposite directions.

[0024] The bottom of the main body 1 is funnel-shaped. A discharge tube 10 is provided at the center of the bottom of the main body 1. The bottom end of the inner sleeve 13 extends into the interior of the discharge tube 10. The bottom end of the outer sleeve 12 extends to the middle of the outer side wall of the inner sleeve 13. A plurality of cross bars 14 are evenly arranged on the outer side wall of the middle part of the inner sleeve 13. The cross bars 14 are perpendicular to the inner sleeve 13. A vertical bar 16 is fixedly arranged at the outer end of the cross bar 14. The vertical bar 16 is parallel to the inner sleeve 13. A plurality of first stirring rods 17 are evenly arranged on the side wall of the vertical bar 16 facing the inner sleeve 13. A plurality of second stirring rods 18 are evenly arranged on the outer side wall of the outer sleeve 12. The first stirring rods 17 and the second stirring rods 18 are arranged in a staggered manner. When the outer sleeve 12 rotates, it drives the second stirring rods 18 to start rotating. When the inner sleeve 13 rotates, it drives the cross bars 14 and the vertical bar 16 to start rotating in the opposite direction to the outer sleeve 12. When the vertical bar 16 rotates, it drives the first stirring rods 17 to start rotating, so that the first stirring rods 17 and the second stirring rods 18 rotate towards each other, fully stirring the materials inside the main body 1 and improving the fermentation effect.

[0025] A spiral blade 15 is fixedly arranged on the outer side wall of the bottom of the inner sleeve 13. The diameter of the spiral blade 15 matches the inner diameter of the discharge tube 10. The bottom end of the spiral blade 15 extends to the outside of the bottom end of the inner sleeve 13. A discharge valve is fixedly arranged at the bottom of the discharge tube 10. The bottom output end of the discharge valve is connected to a receiving tank through a pipeline. When the inner sleeve 13 rotates, it drives the spiral blade 15 at the bottom to start rotating. When the spiral blade 15 rotates, it drives the materials at the bottom of the main body 1 to move upward, thereby fully turning and stirring the materials inside the main body 1, avoiding uneven reaction during fermentation and incomplete fermentation, and further improving the fermentation effect.

[0026] The temperature self-regulating mechanism includes a hot air blower 6, which is fixedly arranged on the left side of the top of the main body 1. An inner hole 33 is formed inside the inner sleeve 13. The output end of the hot air blower 6 is connected to an air outlet pipe through a pipeline. The other end of the air outlet pipe is rotatably connected to the top end of the inner sleeve 13. The output end of the air outlet pipe is connected to the input end of the inner hole 33 through a pipeline. The bottom end of the inner hole 33 penetrates through the cross bar 14 and the vertical bar 16. A diversion cavity is formed inside the first stirring rod 17. The inner hole 33 is communicated with the diversion cavity. A plurality of spray holes 19 are uniformly arranged on the outer side wall of the first stirring rod 17. A one-way valve is arranged at the output end of the spray hole 19. An air outlet 27 is formed in the top of the inner side wall of the main body 1. A filter screen 28 is fixedly arranged outside the air outlet 27. When the first stirring rod 17 rotates, the spray holes 19 on its outer side wall rotate accordingly. At this time, the hot air blower 6 passes hot air flow into the inner part of the inner sleeve 13 through the air inlet pipe 8. The hot air flow flows into the cross bar 14 and the vertical bar 16 along the inner hole 33, and finally enters the diversion cavity inside the first stirring rod 17 and is sprayed out through the spray holes 19 to heat the material. The rotation of the first stirring rod 17 can drive the spray holes 19 to uniformly heat the material inside the main body 1. The one-way valve can prevent the material from flowing into the inside of the diversion cavity.

[0027] A regulating cylinder is fixedly arranged in the middle of the inner sleeve 13. The inner hole 33 vertically penetrates through the center of the regulating cylinder. A pair of slide rails 34 are fixedly arranged on the outer side of the inner hole 33. The pair of slide rails 34 are arranged in parallel. A pair of baffle plates 35 are slidably arranged between the slide rails 34. The baffle plates 35 are perpendicular to the axis of the inner sleeve 13. The baffle plates 35 are rectangular. The length of the baffle plates 35 is greater than the diameter of the inner hole 33. The width of the baffle plates 35 is greater than the radius of the inner hole 33. Two groups of sliding grooves 36 are arranged in the middle of the upper surface of the baffle plates 35. The sliding grooves 36 are perpendicular to the orientation of the slide rails 34. Sliding blocks 37 are slidably arranged inside the sliding grooves 36. The top of the sliding blocks 37 is rotatably connected with connecting rods 38. The adjacent connecting rods 38 are arranged in parallel. The opposite connecting rods 38 are symmetrically arranged.

[0028] The other end of the connecting rod 38 is rotatably connected to the bottom of the adjusting cylinder. At the end of the outer connecting rod 38, an adjusting rod 40 is fixedly arranged. The adjusting rod 40 is perpendicular to the outer connecting rod 38. The other end of the adjusting rod 40 is rotatably connected to a hydraulic rod 41. The interior of the hydraulic rod 41 is filled with a thermosensitive liquid. The other end of the hydraulic rod 41 is fixedly connected to the inner wall of the adjusting cylinder. On the outer wall at the connection between the adjusting cylinder and the hydraulic rod 41, a heat conduction cavity 42 is arranged. The heat conduction cavity 42 is communicated with the inner cavity of the hydraulic rod 41. A spring 43 is arranged around the outside of the hydraulic rod 41. Between the other ends of the connecting rods 38 facing each other inward, a pair of incomplete gears 39 are meshed. When the temperature inside the main body 1 is too high, the thermosensitive liquid inside the hydraulic rod 41 expands due to heat, causing the hydraulic rod 41 to elongate and the spring 43 to be stretched, generating a pulling force in the opposite direction, driving the adjusting rod 40 to rotate towards the inner hole 33. When the adjusting rod 40 moves, it drives the connected connecting rod 38 to rotate towards the inner hole 33, thereby driving the baffle 35 connected to the other end of the connecting rod 38 through the slider 37 to move towards the center of the inner hole 33 along the slide rail 34. When the baffle 35 moves, it drives the connecting rod 38 inside it to rotate accordingly, causing the incomplete gear 39 at the bottom of the inner connecting rod 38 to start rotating. When the incomplete gear 39 rotates, it drives the other incomplete gear 39 meshed with it to rotate towards each other, thereby driving the other baffle 35 to move towards the center of the inner hole 33 synchronously, reducing the flow area of the inner hole 33, thereby reducing the flow rate of the hot air flow and lowering the temperature of the material. Conversely, when the temperature inside the main body 1 is relatively low, the hydraulic rod 41 moves in the reverse direction under the pulling force of the spring 43, driving the baffle 35 to move towards both sides of the slide rail 34, increasing the flow area of the inner hole 33, increasing the flow rate of the hot air flow, and raising the temperature of the material, thus realizing the control of the fermentation temperature and avoiding the influence of too high or too low temperature on the fermentation effect.

[0029] The humidity synchronous control mechanism includes a dehumidification chamber 20. The dehumidification chamber 20 is fixedly arranged at the top of the inner side wall of the main body 1. On the lower side of the side wall of the dehumidification chamber 20 facing the outer sleeve 12, a one-way permeable membrane 21 is arranged. At the inner bottom of the dehumidification chamber 20, a filter plate 48 is fixedly arranged. On the top of the filter plate 48, a sponge 47 is arranged. During fermentation, the material is evenly heated by the rotation of the spray holes 19 to ensure that the material is at a constant temperature during heating. When the material ferments, water vapor is generated. The sponge 47 can absorb the excess water vapor inside the main body 1 through the one-way permeable membrane 21 to keep the humidity inside the main body 1 constant and avoid too high humidity inside the fermentation tank.

[0030] A pressing plate 46 is movably arranged on the top of the sponge 47. An inclined block 45 is fixedly arranged on the top of the pressing plate 46. The top of the inclined block 45 is inclined. The bottommost end of the top of the inclined block 45 faces the rotation direction of the vertical rod 16. A top rod 24 is fixedly arranged at the top of the vertical rod 16. A rotating rod 25 is fixedly arranged on one side of the top end of the top rod 24 facing the inner wall of the main body 1. The other end of the rotating rod 25 extends to the top of the dehumidification chamber 20. A roller 26 is rotatably arranged at the bottom of the other end of the rotating rod 25. The bottom height of the roller 26 matches the bottommost height of the top of the inclined block 45. When the vertical rod 16 rotates, it drives the top rod 24 at its top to start rotating, causing the rotating rod 25 to rotate accordingly. When the rotating rod 25 rotates, it drives the roller 26 to start rotating. When the roller 26 moves to contact the top of the inclined block 45, the inclined block 45 moves downward under the downward pressure, causing the pressing plate 46 to move downward. When the pressing plate 46 moves downward, it squeezes the sponge 47, thereby squeezing out the water in the sponge 47 and realizing continuous absorption of water vapor.

[0031] A liquid outlet 49 is opened at the bottom of the dehumidification chamber 20. A liquid storage tank 22 is fixedly arranged on the outer side wall of the main body 1. An inclined hole 23 is connected by a pipeline between the liquid outlet 49 and the liquid storage tank 22. The water in the sponge 47 flows out along the liquid outlet 49 and finally flows into the inside of the liquid storage tank 22 along the inclined hole 23, thereby realizing centralized collection of water and facilitating its treatment.

[0032] Working principle: When the drive motor 7 operates, it drives the drive bevel gear 30 to start rotating through the rotating shaft 29, causing the upper driven bevel gear 31 and the lower driven bevel gear 32 meshing with it to start rotating in opposite directions. When the upper driven bevel gear 31 and the lower driven bevel gear 32 rotate, they drive the outer sleeve 12 and the inner sleeve 13 to start rotating in opposite directions. When the outer sleeve 12 rotates, it drives the second stirring rod 18 to start rotating. When the inner sleeve 13 rotates, it drives the cross bar 14 and the vertical rod 16 to start rotating in the opposite direction to the outer sleeve 12. When the vertical rod 16 rotates, it drives the first stirring rod 17 to start rotating, causing the first stirring rod 17 and the second stirring rod 18 to rotate towards each other, fully stirring the materials inside the main body 1 and improving the fermentation effect; when the inner sleeve 13 rotates, it drives the spiral blade 15 at the bottom to start rotating. When the spiral blade 15 rotates, it drives the materials at the bottom of the main body 1 to move upward, thereby fully turning and stirring the materials inside the main body 1, avoiding uneven reaction during fermentation and incomplete fermentation, and further improving the fermentation effect.

[0033] When the first stirring rod 17 rotates, the spray holes 19 on its outer sidewall rotate accordingly. At this time, the hot air blower 6 passes hot air flow into the interior of the inner sleeve 13 through the air inlet pipe 8. The hot air flow flows into the cross bar 14 and the vertical bar 16 along the inner hole 33, and finally enters the flow dividing cavity inside the first stirring rod 17, and is sprayed out through the spray holes 19 to heat the material. The rotation of the first stirring rod 17 can drive the spray holes 19 to uniformly heat the material inside the main body 1. The one-way valve can prevent the material from flowing into the interior of the flow dividing cavity. When the temperature inside the main body 1 is too high, the heat-sensitive liquid inside the hydraulic rod 41 expands due to heat, causing the hydraulic rod 41 to elongate and the spring 43 to stretch, generating a pulling force in the opposite direction, driving the adjusting rod 40 to rotate towards the inner hole 33. When the adjusting rod 40 moves, it drives the connecting rod 38 connected to it to rotate towards the inner hole 33, thereby driving the baffle 35 connected to the other end of the connecting rod 38 through the slider 37 to move towards the center of the inner hole 33 along the slide rail 34. When the baffle 35 moves, it drives the connecting rod 38 on its inner side to rotate accordingly, causing the incomplete gear 39 at the bottom of the inner connecting rod 38 to start rotating. When the incomplete gear 39 rotates, it drives the other incomplete gear 39 meshing with it to rotate towards each other, thereby driving the other baffle 35 to move towards the center of the inner hole 33 synchronously, reducing the flow area of the inner hole 33, thereby reducing the flow rate of the hot air flow and lowering the temperature of the material. On the contrary, when the temperature inside the main body 1 is relatively low, the hydraulic rod 41 moves in the reverse direction under the pulling force of the spring 43, driving the baffle 35 to move towards both sides of the slide rail 34, increasing the flow area of the inner hole 33, increasing the flow rate of the hot air flow, and raising the temperature of the material, thereby realizing the control of the fermentation temperature and avoiding the influence of too high or too low temperature on the fermentation effect.

[0034] During fermentation, the material is uniformly heated by the rotation of the spray holes 19 to ensure that the material is at a constant temperature during heating. When the material ferments, water vapor is generated. The sponge 47 can absorb the excess water vapor inside the main body 1 through the one-way permeable membrane 21, maintaining the humidity inside the main body 1 constant and avoiding too high humidity inside the fermentation tank. When the vertical bar 16 rotates, it drives the top rod 24 at its top to start rotating, causing the rotating rod 25 to rotate accordingly. When the rotating rod 25 rotates, it drives the roller 26 to start rotating. When the roller 26 moves to contact the top of the inclined block 45, the inclined block 45 moves downward under the downward pressure, causing the pressing plate 46 to move downward. When the pressing plate 46 moves downward, it squeezes the sponge 47, thereby squeezing out the water in the sponge 47 and realizing the continuous absorption of water vapor. The water in the sponge 47 flows out along the liquid outlet 49 and finally flows into the interior of the liquid storage tank 22 along the inclined hole 23, thereby realizing the centralized collection of water for easy treatment.
