[0020] Step 2: The gear shaft drives the stirring blade to rotate on the horizontal frame, and the stirring blade reciprocates up and down to stir the light black beans in the fermentation box;

[0024] Step 6: The diffusion plate will swing back and forth under the action of spring 4, blowing the hot air sprayed from the hot air nozzle evenly to different positions on the upper side of the fermentation box.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. In the present invention, light fermented black beans are poured into a fermentation box, a heating plate is started to heat and ferment the light fermented black beans, a motor is started to drive the eccentric wheel shaft to rotate, and the eccentric wheel shaft drives the scraper to rotate, and the scraper is arranged to facilitate scraping the light fermented black beans adhered to the inner wall of the fermentation box and the bottom of the fermentation box, thereby reducing the situation that the light fermented black beans adhere for a long time, causing it to be difficult to clean and deteriorate, and the situation that the fermentation temperature is uneven due to long-term adhesion, resulting in poor fermentation quality.

[0027] 2. In the present invention, when the eccentric wheel shaft rotates, the cross frame will also be driven to rotate, and the cross frame will drive the gear shaft and the stirring blade to rotate synchronously. The lower side of the gear shaft is square, so when the gear shaft rotates, it will be meshed with the gear ring plate and rotate. Then the gear shaft will also drive the stirring blade to rotate on the cross frame, which is beneficial to stirring the light black beans in the fermentation box, and promoting the temperature of the light black beans in the fermentation box to be evenly diffused to different positions in the fermentation box, ensuring the uniform temperature inside the fermentation box and ensuring the quality of fermentation.

[0028] 3. In the present invention, when the stirring blade rotates, it will also drive the magnetic rod to rotate synchronously. When the magnetic rod rotates to the lower side of the magnetic block circle, it will be subjected to magnetic repulsion, and then the magnetic rod drives the stirring blade to slide downward on the gear shaft, compressing spring one. When the magnetic rod rotates away from the lower side of the magnetic block circle, spring one resets the stirring blade, realizing the up and down reciprocating motion of the stirring blade, which is beneficial to improving the uniform stirring quality of the light black beans, thereby ensuring the uniform temperature in the fermentation box.

[0029] 4. In the present invention, when the stirring blade reciprocates up and down, it will also drive the shovel frame and the magnetic movable plate to rotate up and down synchronously. When the shovel frame rotates and descends, it will scoop up the light black beans on the lower side of the fermentation box. When the magnetic movable plate rotates to the side close to the magnetic strip on the lower side, the magnetic strip on the lower side will generate a magnetic repulsive force on the left end of the magnetic movable plate, pushing the magnetic movable plate to slide on the lower end of the shovel frame, so that the through holes on the magnetic movable plate and the shovel frame are misaligned with each other. When the shovel frame rotates and rises, it can smoothly scoop up the light black beans on the lower side of the fermentation box. When the magnetic movable plate rotates to the side close to the upper magnetic strip, the upper magnetic strip generates magnetic attraction to the magnetic movable plate, so that the magnetic movable plate slides and resets at the lower end of the shovel frame. At this time, the magnetic movable plate and the through holes on the shovel frame are aligned with each other, which is conducive to the light black beans on the lower side of the shovel frame scooped up and falling back into the fermentation box, realizing the up and down flipping of the light black beans at different heights in the fermentation box, thereby ensuring that the light black beans at different heights inside the fermentation box can have a uniform temperature, thereby ensuring the quality of fermentation.

[0030] 5. In the present invention, when the gear shaft rotates, it will also drive the top bar to rotate, the top bar pushes the extrusion inclined block, the inclined block drives the arc-shaped stirring plate to rotate in an arc on the scraping bar, compressing the second spring. Since the lower end of the arc-shaped stirring plate is in contact with the bottom of the fermentation box, the arc-shaped stirring plate is convenient for lifting the light black beans at the bottom of the fermentation box upward, avoiding the light black beans at the bottom of the fermentation box from gathering at the bottom of the fermentation box for a long time, making it difficult to turn over, and also avoiding the light black beans at the bottom from being overheated for a long time, resulting in caking, causing fermentation failure, and also ensuring uniform heating and fermentation of the light black beans.

[0031] 6. In the present invention, when the eccentric wheel shaft rotates, it will also squeeze the pressure plate, push the pressure plate to move toward the airbag, squeeze the airbag, compress spring three, and the gas in the airbag is blown into the gas channel through the air pipe, and blown to the upper side of the fermentation box from the hot air nozzle, so that the temperature inside the fermentation box is uniform, thereby ensuring the fermentation quality of the light black beans.

[0032] 7. In the present invention, when the eccentric wheel shaft rotates, it will drive the baffle to move up and down on the guide rod. The baffle reciprocates to open and close the hot gas nozzle without affecting the normal air intake of the hot gas nozzle. When not in use, the baffle blocks the hot gas nozzle to avoid blockage at the hot gas nozzle mouth, thereby ensuring the normal operation of the hot gas nozzle.

[0033] 8. In the present invention, when the baffle moves downward, it will drive the flexible strips to move downward synchronously. The flexible strips will pull the diffusion plate to rotate downward at the top of the fermentation box, stretching the spring four. At the same time, the flexible strips will gradually deform until the flexible strips are separated from the diffusion plate. The spring four drives the diffusion plate to reset. Under the action of the spring four, the diffusion plate will swing back and forth, which is conducive to evenly blowing the hot air sprayed from the hot air nozzle to different positions on the upper side of the fermentation box, thereby achieving uniform temperature at the top of the fermentation box and ensuring the quality of fermentation.

When the magnetic movable plate 13 rotates to the side close to the upper magnetic strip 14, the upper magnetic strip 14 generates a magnetic attraction on the magnetic movable plate 13, so that the magnetic movable plate 13 slides and resets at the lower end of the shovel frame 12. At this time, the magnetic movable plate 13 and the shovel frame The through holes on 12 are aligned with each other, which is conducive to the light black beans on the inner lower side scooped up in the shovel frame 12 falling back into the fermentation box 1, realizing the up and down flipping of the light black beans at different heights in the fermentation box 1, thereby ensuring that the light black beans at different heights inside the fermentation box 1 can have a uniform temperature and ensure the quality of fermentation.

[0058] Working principle:

[0059] When the present invention is used, light black beans are poured into the fermentation box 1, the heating plate 101 is started to heat and ferment the light black beans, the motor 2 is started to drive the eccentric wheel shaft 3 to rotate, and the eccentric wheel shaft 3 drives the scraper 4 to rotate. The scraper 4 is arranged to facilitate the scraping of the light black beans adhered to the inner wall of the fermentation box 1 and the bottom of the fermentation box 1, thereby reducing the situation that the light black beans adhere for a long time, causing it to be difficult to clean and deteriorate, and the situation that the fermentation temperature is uneven due to long-term adhesion, resulting in poor fermentation quality. When the eccentric wheel shaft 3 rotates, the horizontal frame 5 is also driven to rotate, and the horizontal frame 5 drives the gear shaft 6 and the stirring blade 7 to rotate synchronously. The lower side of the gear shaft 6 is square, so when the gear shaft 6 rotates, it will be meshed by the gear ring plate 9 and rotate on its own, and then the gear shaft 6 will also drive the stirring blade 7 to rotate on the horizontal frame 5. The self-rotation on the top of the stirring box 1 is conducive to stirring the light black bean in the fermentation box 1, and the temperature of the light black bean in the fermentation box 1 can be evenly diffused to different positions in the fermentation box 1, ensuring the uniform temperature inside the fermentation box 1 and the quality of fermentation. When the stirring blade 7 rotates, the magnetic rod 10 will also be driven to rotate synchronously. When the magnetic rod 10 rotates to the lower side of the magnetic block circle 11, it will be subjected to magnetic repulsion, and then the magnetic rod 10 drives the stirring blade 7 to slide downward on the gear shaft 6, compressing the spring 18. When the magnetic rod 10 rotates away from the lower side of the magnetic block circle 11, the spring 18 resets the stirring blade 7, realizing the up and down reciprocating motion of the stirring blade 7, which is conducive to improving the uniform stirring quality of the light black bean, thereby ensuring the uniform temperature in the fermentation box 1. When the blade 7 reciprocates up and down, it will also drive the shovel frame 12 and the magnetic movable plate 13 to rotate up and down synchronously. When the shovel frame 12 rotates and descends, it will scoop up the light black beans on the lower side of the fermentation box 1. When the magnetic movable plate 13 rotates to the side close to the lower magnetic strip 14, the lower magnetic strip 14 will generate a magnetic repulsive force on the left end of the magnetic movable plate 13, pushing the magnetic movable plate 13 to slide at the lower end of the shovel frame 12, so that the through holes on the magnetic movable plate 13 and the shovel frame 12 are misaligned with each other. When the shovel frame 12 rotates and rises, it can smoothly scoop up the light black beans on the lower side of the fermentation box 1. When the magnetic movable plate 13 rotates to the side close to the upper magnetic strip 14, the upper magnetic strip 14 generates a magnetic attraction on the magnetic movable plate 13, so that the magnetic movable plate 13 slides and resets at the lower end of the shovel frame 12. At this time, the magnetic movable plate 13 The movable plate 13 and the through holes on the shovel frame 12 are aligned with each other, which is conducive to the light black beans on the inner lower side scooped up in the shovel frame 12 falling back into the fermentation box 1, realizing the up and down flipping of the light black beans at different heights in the fermentation box 1, thereby ensuring that the light black beans at different heights inside the fermentation box 1 can have a uniform temperature, ensuring the quality of fermentation. When the gear shaft 6 rotates, it will also drive the top bar 18 to rotate, and the top bar 18 pushes the extrusion inclined block 17, and the inclined block 17 drives the arc-shaped stirring plate 15 to rotate in an arc on the scraping bar 4, compressing the spring 2 16. Since the lower end of the arc-shaped stirring plate 15 is in a fit with the bottom of the fermentation box 1, the arc-shaped stirring plate 15 is convenient for lifting the light black beans at the bottom of the fermentation box 1 upwards, avoiding the light black beans at the bottom of the fermentation box 1 from accumulating at the bottom of the fermentation box 1 for a long time.When the eccentric wheel shaft 3 rotates, it will also squeeze the pressing plate 24, push the pressing plate 24 to move in the direction of the air bag 22, squeeze the air bag 22, compress the spring three 23, and the gas in the air bag 22 will be blown into the gas channel 19 through the air pipe 21, and blown from the hot air nozzle 20 to the upper side of the fermentation box 1, so that the internal temperature of the fermentation box 1 is uniform, thereby ensuring the fermentation quality of the light black bean curd. When the eccentric wheel shaft 3 rotates, it will drive the baffle 25 to move up and down on the guide rod 26, and the baffle 25 will reciprocate to open and close the hot air nozzle 20 without affecting the normal operation of the hot air nozzle 20. When the air is normally inletted and not in use, the baffle 25 blocks the hot air nozzle 20 to prevent the hot air nozzle 20 from being blocked, thereby ensuring the normal operation of the hot air nozzle 20. When the baffle 25 moves downward, it will drive the flexible strip 29 to move downward synchronously. The flexible strip 29 will pull the diffusion plate 27 to rotate downward at the top of the fermentation box 1, stretching the spring four 28. At the same time, the flexible strip 29 will gradually deform until the flexible strip 29 and the diffusion plate 27 are separated. The spring four 28 drives the diffusion plate 27 to reset. Under the action of the spring four 28, the diffusion plate 27 will swing back and forth, which is conducive to evenly blowing the hot air ejected from the hot air nozzle 20 to different positions on the upper side of the fermentation box 1, achieving a uniform temperature at the top of the fermentation box 1 and ensuring the quality of fermentation.
