Description

Technical Field

[0001] The invention relates to the technical field of dough proofing machines, in particular to a dough proofing machine capable of improving air circulation at the bottom of dough. Background Art

[0002] A dough proofing machine is a device specially used for dough fermentation and proofing. It is widely used in the production process of bread, steamed buns, dumplings and other flour products. It provides a stable proofing environment for the dough by controlling temperature, humidity and air circulation, promotes the fermentation of yeast, and makes the dough reach an ideal soft and expanded state.

[0003] For example, the patent with publication number CN218354382U discloses a dough fermentation box, which utilizes the temperature in the constant temperature zone and the moisture of the dough to thaw, so as to prevent the dough that has not been thawed from being immediately placed in an environment with rising temperature. The dough will be affected by the surface first contacting the temperature, resulting in different fermentation degrees inside and outside the dough. However, in actual use, since the bottom of the dough will always be in contact with the supporting surface in the fermentation box, the air circulation here is low, the proofing speed is slow, resulting in uneven proofing of the dough as a whole, and the bottom of the dough is also prone to adhesion and cracking.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a dough proofing machine that can improve the air circulation at the bottom of the dough is proposed. Summary of the invention

The upper end of the driving plate is rotatably connected to the driving sleeve, and a cam is fixed to one side of the driving sleeve, and a sliding rod is slidably connected to one side of the cam.

[0012] Furthermore, the humidifying assembly also includes a spring, a fixed plate and a piston. The outer side of the sliding rod is sleeved with a spring, and the end of the spring is connected to the fixed plate. The fixed plate is fixedly connected to the box body, and the end of the fixed plate is provided with a piston.

[0013] Furthermore, the humidification component also includes a fixed cylinder, a one-way valve, a water tank and a spray tube.

[0016] The present invention provides a dough proofing machine capable of improving air circulation at the bottom of dough, which has the following beneficial effects:

[0017] 1. When the dough is placed on the bracket for proofing, the servo motor can also drive the rotating plate to rotate inside the partition through the driving shaft, the active gear and the gear ring, so that the lifting rod can move along the outer side of the guide ring. At the same time, the groove on the outer side of the guide ring will limit the roller. Therefore, when the rotating plate rotates, the bracket on the lifting rod can be controlled to automatically lift and lower. Since the supporting part of the bracket is in a strip shape and has a certain gap, when a single bracket supports the bottom of the dough, part of the airflow can circulate at the bottom of the dough, and the reciprocating switching can reduce the obstruction, which is conducive to the uniform proofing of the dough. When the rotating plate rotates counterclockwise, the higher bracket will stop lifting and lowering, and the other bracket will move to a higher place. After being flush, the originally higher bracket will move down under the action of the guide groove on the outer side of the guide ring. Therefore, in the process of switching the brackets, the overall stability of the dough can be maintained to avoid the dough from falling due to excessive shaking.

[0018] 2. The drive shaft of the present invention can also drive the first fan blade to work through the bevel gear set, the synchronous shaft and the gear commutator, so that a high-pressure area is formed at one end of the interior of the fixed box, and blown toward the dough through the porous diverter plate, which is beneficial to improving the air circulation performance around the dough. At the same time, the temperature inside the fixed box is conveniently controlled by the temperature sensor and the heating wire, so as to create a temperature environment suitable for the active yeast and improve the efficiency of dough proofing. In the process of the airflow blowing toward the dough, the dough itself will also rotate in response to the rotation of the rotating plate, thereby changing the position when receiving the wind, so that the outside is more evenly in contact with the airflow, and the reflux pipe can be used to allow the air inside the box to flow back to the fixed box, so that the air circulates inside the box, reducing the temperature leakage with the air, which is beneficial to achieve the effect of energy saving.

[0019] 3. The present invention utilizes a humidity sensor to monitor the humidity inside the box body, and when the ambient humidity is too low, the dough surface may crack due to drying or adhere to the bracket. At this time, the electric push rod can be started by the controller, so that the driving plate drives the driving sleeve to slide on the driving shaft, so that the outer end of the cam contacts the end of the sliding rod. At this time, the driving shaft will drive the cam to rotate during operation, thereby pushing the sliding rod, so that the piston squeezes the pure water inside the fixed cylinder into the spray pipe through the upper one-way valve, and humidifies the inside of the fixed box through the atomizing nozzle outside the spray pipe, so that the inside of the box meets the humidity environment for dough fermentation, and in the process of rotation of the driving shaft, when the sliding rod is separated from the convex part of the cam, the spring will push the sliding rod under the limit of the fixed plate, so that negative pressure can be formed inside the fixed cylinder, so that the pure water inside the water tank is sucked into the fixed cylinder through the lower one-way valve, and the replenishment operation can be automatically performed, and when the humidity meets the fermentation requirements, as the electric push rod is extended, the cam and the sliding rod can be separated, and the humidification can be stopped at this time.

[0020] 4. During the rotation of the rotating plate of the present invention, the connecting frame will also be driven to rotate synchronously, so that all the rotating shafts make circular motions, and during the movement of the rotating shafts, the planetary gears will contact the inner rack and the outer rack respectively, so that the rotating shafts make intermittent reciprocating rotations. Therefore, the air flow inside the box can be made more disordered through the second fan blades, and the temperature and humidity distribution is more uniform. At the same time, the angles of the second fan blades adjacent to each other in the circumferential direction are opposite, so that different second fan blades can have different wind directions when they move to the same position, further improving the uniformity of temperature and humidity inside the box.

At the same time, the temperature sensor 409 and the heating wire 406 are used to conveniently control the temperature inside the fixed box 405, create a temperature environment suitable for the active yeast, and improve the efficiency of dough fermentation. In the process of the airflow blowing to the dough, the dough itself will also rotate in response to the rotation of the rotating plate 305, thereby changing the position when receiving the wind, so that the outer side is more evenly in contact with the airflow, and the return pipe 408 can be used to allow the air inside the box 1 to flow back to the fixed box 405, so that the air circulates inside the box 1.

[0033] The specific operation is as follows. When the humidity sensor 501 detects that the humidity inside the box body 1 is too low, the controller can start the electric push rod 502, so that the driving plate 503 drives the driving sleeve 504 to slide on the driving shaft 302, so that the outer end of the cam 505 contacts the end of the sliding rod 506. At this time, the driving shaft 302 will drive the cam 505 to rotate during operation, thereby pushing the sliding rod 506, so that the piston 509 squeezes the pure water inside the fixed cylinder 510 into the spray pipe 513 through the upper one-way valve 511, and humidifies the inside of the fixed box 405 through the atomizing nozzle outside the spray pipe 513, so that the inside of the box body 1 meets the humidity environment for dough proofing, and in the process of rotation of the rotating plate 305, it will also drive the connecting frame 601 to rotate synchronously, so that all the rotating shafts 602 make circular motions, and in the process of movement of the rotating shafts 602, the planetary gears 604 will also be respectively connected to the inner rack 605 and the outer rack. 506 contacts with the strip 606, thereby making the rotating shaft 602 do intermittent reciprocating rotation, so that the second fan blade 603 can make the air flow inside the box body 1 more disordered and the temperature and humidity distribution more uniform, and at the same time, the blade angles of the second fan blades 603 adjacent to each other in the circumferential direction are opposite, so that different second fan blades 603 can have different wind directions when they move to the same position, further improving the uniformity of the temperature and humidity inside the box body 1, and as the driving shaft 302 continues to rotate, when the slide bar 506 is separated from the convex part of the cam 505, the spring 507 will push the slide bar 506 under the limit of the fixed plate 508, so that negative pressure can be formed inside the fixed cylinder 510, so that the pure water inside the water tank 512 is sucked into the fixed cylinder 510 through the one-way valve 511 at the bottom, and the replenishing operation can be automatically performed, and when the humidity meets the requirements of proofing, as the electric push rod 502 extends, the cam 505 can be separated from the slide bar 506, and the humidification can be stopped at this time.

[0034] In summary, when using the dough proofing machine that can improve the air circulation at the bottom of the dough, first open the box door, place the dough on the bracket 307, and after closing the box door, start the servo motor 301 through the controller, so that it drives the rotating plate 305 to rotate inside the partition 2 through the driving shaft 302, the active gear 303 and the ring gear 304, so that the lifting rod 306 can move along the outside of the guide ring 309, and at the same time, the groove on the outside of the guide ring 309 will limit the roller 308. Therefore, when the rotating plate 305 rotates counterclockwise, the bracket 307 on the lifting rod 306 can be controlled to automatically perform a lifting operation. During this process, the higher bracket 307 will stop lifting, and the other bracket 307 will move to a higher place, and after being flush, the originally higher bracket 307 will stop lifting. The high bracket 307 will move downward under the action of the guide groove on the outer side of the guide ring 309. At the same time, since the support part of the bracket 307 is in a strip shape and has a certain gap, part of the air flow can circulate at the bottom of the dough. Then, when the humidity sensor 501 detects that the humidity inside the box body 1 is too low, the controller can start the electric push rod 502, so that the driving plate 503 drives the driving sleeve 504 to slide on the driving shaft 302, so that the outer end of the cam 505 contacts the end of the sliding rod 506. At this time, the driving shaft 302 will drive the cam 505 to rotate during operation, so as to push the sliding rod 506, so that the piston 509 squeezes the pure water inside the fixed cylinder 510 into the spray pipe 513 through the upper one-way valve 511, and then the pure water outside the spray pipe 513 is discharged. The atomizing nozzle on the side is used to humidify the inside of the fixed box 405. Secondly, the driving shaft 302 also drives the first fan blade 404 to work through the bevel gear set 401, the synchronous shaft 402 and the gear commutator 403, so that a high-pressure area is formed at one end of the interior of the fixed box 405, and blows toward the dough through the porous diverter plate 407. At the same time, the temperature sensor 409 and the heating wire 406 are used to conveniently control the temperature inside the fixed box 405. In the process of the air flow blowing toward the dough, the dough itself will also rotate in response to the rotation of the rotating plate 305, thereby changing the position when receiving the wind. In addition, the return pipe 408 can be used to allow the air inside the box body 1 to flow back into the fixed box 405. Then, in the process of the rotating plate 305 rotating, it will also drive the connecting frame 60 1 rotates synchronously, so that all the rotating shafts 602 make circular motion, and in the process of the rotating shaft 602 moving, the planetary gear 604 will contact the inner rack 605 and the outer rack 606 respectively, so that the rotating shaft 602 makes intermittent reciprocating rotation, so that the air flow inside the box body 1 can be made more disordered through the second fan blade 603, and the temperature and humidity distribution can be more uniform. Finally, as the driving shaft 302 continues to rotate, when the slide bar 506 is separated from the convex part of the cam 505, the spring 507 will push the slide bar 506 under the limit of the fixed plate 508, so that negative pressure can be formed inside the fixed cylinder 510, so that the pure water inside the water tank 512 is sucked into the fixed cylinder 510 through the one-way valve 511 at the bottom, and when the humidity meets the requirements of proofing,As the electric push rod 502 extends, the cam 505 and the slide rod 506 can be separated, and the humidification operation is automatically stopped, which is convenient for controlling the environment during dough proofing.
