Description

Technical Field

[0001] This invention relates to the technical field of food manufacturing, specifically to a bread dough fermentation device and fermentation method. Background Technology

[0002] Fermentation is a crucial step in bread production. Yeast breaks down the sugars in the dough into gases such as carbon dioxide, causing the dough to expand and form an ideal soft, porous structure. Fermentation directly affects the volume, texture, flavor, and batch consistency of bread. Traditional production relies mainly on manual observation of dough volume changes or simple timing, which is not only labor-intensive and inefficient but also highly susceptible to environmental temperature and dough recipe, easily leading to under-fermentation or over-fermentation. Current methods for detecting dough fermentation typically employ natural diffusion or simple vacuum sampling. However, dough has high viscoelasticity, and the large amount of CO2 generated inside is tightly wrapped by the dough's network structure, making it difficult to completely release through passive vacuuming. As a result, the detection data cannot accurately reflect the overall degree of fermentation. Furthermore, by extracting a small amount of gas, a large amount of flour particles, yeast residue, and condensed water droplets are carried away, leading to sensor contamination, zero-point drift, and large fluctuations in readings. This forces the equipment to be frequently shut down for cleaning or to adopt indirect detection, which seriously affects continuous production efficiency. Summary of the Invention

[0013] In one embodiment, a bread dough fermentation method is also included, as shown below: S1. After kneading the dough until smooth, insert it into the fermentation shell, insert the snap-fit ​​plate, and fit the curved push plate with the dough to clamp it. Then place it in an appropriate area for fermentation. S2. After fermentation, the fermentation chamber is transferred to the screening mechanism. The screening mechanism checks the length of the aeration pipe in the fermentation chamber. If the length does not meet the requirements, fermentation continues. S3. Squeeze the vent tube to push the arc-shaped push plate into the fermentation shell. Gas is introduced into the sensor module through the vent tube to detect its relevant parameters. The unqualified part is marked and transferred out of the screening mechanism, and the qualified part passes through the screening mechanism to the shell-breaking mechanism. S4. After disassembling the snap-fit ​​plate using the shell-removing mechanism, push the vent pipe to drive the arc-shaped push plate to pass the embryo out of the fermentation shell. Then, use the material collection mechanism to scrape the embryo and transfer it to other parts to complete the fermentation.

[0014] The beneficial effects of this invention are: a bread dough fermentation device and method with a simple structure, effective detection of fermentation effect, avoidance of sensor contamination, and improved detection efficiency. The specific implementation method is as follows: First, after the dough is tanned manually or by machine, an equal weight of dough is fed into the fermentation chamber. Then, a connecting plate is inserted into the fermentation chamber, and the chamber is placed in the fermentation area or fermentation equipment for fermentation. During fermentation, the dough expands in volume, causing an arc-shaped pusher to push the vent pipe through the arc-shaped top cover. The fermentation volume or effect can be judged by detecting the height of the arc-shaped top cover. Afterwards, the dough is transferred to a screening mechanism for screening. The specific implementation method is as follows: After placing the vent pipe of the fermentation chamber between two sets of flared baffles, an electric conveyor wheel is used to rotate, driving the fermentation chamber into the shell-opening mechanism area. During this process, as the limit baffle guides the vent pipe, the lifting rod is activated to lift the lifting plate, which in turn lifts the limit baffle, causing it to tilt. This allows the fermentation chamber to gradually skip the limit baffle guide during its movement. If the vent pipe extends too far out of the fermentation box, it cannot continue to guide the dough, indicating insufficient fermentation inside. The dough, now unrestrained by the limit bar, will tilt and fall onto the inclined receiving plate below, flowing into the transfer mechanism for further processing. If the vent pipe extends too far, when passing through the pressing plate area, the electric conveyor wheel below the pressing lifting rod is activated, using the pressing plate to press the vent pipe into the fermentation shell cavity. This squeezes the dough inside, releasing air. Simultaneously, the top rod at the end of the guide pipe presses the pressing ball, and the pressing rod pushes the sealing plug downwards to overcome the spring tension. The gas generated by pressing the dough inside the fermentation shell falls through the vent pipe into the guide pipe and is detected by other sensors to determine if it meets requirements. If it does, the lifting rod descends and guides the dough to the shell-opening mechanism; otherwise, the lifting rod is raised to cancel the guidance, and the dough falls below the inclined receiving plate, completing the screening process.

[0015] Meanwhile, during the pressing process of the arc-shaped pusher plate, powder, liquid or yeast residue in the fermentation shell will flow out through the vent pipe to the contamination sensor. As the gas flows out through the gap between the fermentation shell and the pressing ball, the pocket groove formed by the bending baffle and the inner cavity of the fermentation shell collects the above-mentioned impurities. After completion, they fall into the vent pipe. Subsequently, the vent pipe can be cleaned by using air to backwash the vent pipe and the impurities can be discharged from the vent pipe, thus completing the treatment of impurities.

[0016] After falling into the upper area, the dough is guided by the box guide frame to fall between the symmetrical rollers. Specifically, the position or width of the box guide frame can be adjusted according to the actual movement rules to ensure that the dough falls between the rollers. After falling between the rollers, it will not slip off due to the overlapping of the skirt on the outer side of the fermentation shell. Then, the turntable wheel is rotated. During the rotation of the turntable wheel, the turntable wheel moves the fastening plate to pass through the fermentation shell, and at the same time, the fermentation shell will also clean the dough off the swing rod. After completion, the dough will remain sticky inside the fermentation shell. At this time, the rotary motor is started to drive the gear receiving plate to rotate. At the same time, the meshing gear moves the fixed rod to rotate, which drives the swing rod to rotate away from the bottom of the fermentation box until the vent pipe points to the push rod lifting rod. Then, the rotation of the gear receiving plate is stopped and the push rod lifting rod is started. The push rod pushes the vent pipe to expel the dough from the fermentation chamber. During the start of the push rod lifting rod, the drive motor rotates the rotating shaft, causing the conveyor belt at the top of the feeding plate to abut against the inner edge of the fermentation chamber. Under the action of the push rod lifting rod, the vent pipe is pushed to expel the dough from the fermentation chamber. Then, the drive motor continues to rotate, using the rotation of the conveyor belt to scrape the dough inside the bending baffle. After scraping the entire dough, the roller motor is started to drive the conveyor belt to move, causing the dough to fall onto the surface of the conveyor belt at the outer end of the feeding plate. Then, the rotating shaft is rotated in the opposite direction, using centrifugal force to throw the dough out and collect it. After the dough is collected, the gear receiving tray continues to rotate, so that the vent pipe faces the equipment support surface, and the fermentation chamber can be collected. After cleaning, it can be re-fermented.

[0017] Because the screening mechanism is relatively tall, to facilitate the guidance of the fermentation shells by the screening mechanism, the fermentation boxes collected by the inclined receiving plate fall onto the horizontal conveyor belt. Depending on the falling conditions, fermentation can continue or the damaged embryos can be processed. After completion, the fermentation boxes are manually or mechanically fed back onto the inclined conveyor belt and then transported between the threaded conveyor rod and the rotating conveyor rod. When the conveyor rod motor is started to rotate the threaded conveyor rod, the threaded guide of the threaded conveyor rod moves the fermentation box to the vicinity of the screening mechanism. Then, guided by the arc-shaped baffle, the fermentation box is moved between the flared baffles, completing the transport of the fermentation box.

[0018] This equipment has a simple structure and effectively utilizes the guiding effect of the fermentation chamber and the compression of the embryo to detect the internal gas. At the same time, it effectively prevents impurities from falling into the sensor, effectively detects the fermentation effect, and avoids sensor contamination. It has good practicality and economy, which is beneficial to the promotion and use of the equipment. Attached Figure Description

[0031] Also beneficial is a method for fermenting bread dough, as shown below: S1. After kneading the dough evenly, it is put into the fermentation shell 21. Specifically, the dough and the dough portioning are existing technologies. The dough can be put into the fermentation shell 21 by existing technical means. Insert the snap-fit ​​plate 26 and attach the arc-shaped push plate to the dough and clamp it with the snap-fit ​​plate 26. Place it in an appropriate area for fermentation. S2. After the fermentation tank 2 is transferred to the screening mechanism 1, the screening mechanism 1 checks the outlet length of the aeration pipe 22 in the fermentation tank 2. If the length does not meet the requirements, fermentation continues. S3. Squeeze the vent pipe 22 to push the arc-shaped push plate into the fermentation shell 21. Gas is introduced into the sensor module through the vent pipe 22 to detect its relevant parameters. The unqualified part is marked and transferred out of the screening mechanism 1, and the qualified part passes through the screening mechanism 1 to the shell-breaking mechanism 3. S4. After disassembling the snap-fit ​​plate 26 using the shell-removing mechanism 3, push the vent pipe 22 to drive the arc-shaped push plate to pass the embryo out of the fermentation shell 21. Then, use the material collection mechanism 4 to scrape the embryo and transfer it to other parts to complete the fermentation.

[0032] Working principle of this invention: First, after the dough is tanned manually or by equipment, an equal mass of dough is fed into the fermentation shell 21. Then, the snap-fit ​​plate 26 is inserted into the fermentation shell 21, and the dough is placed in the fermentation area or fermentation equipment for fermentation. During fermentation, the dough expands in volume, causing the arc-shaped pusher plate to push the vent pipe 22 out of the arc-shaped top cover 211. The fermentation volume or effect can be judged by detecting the height of the arc-shaped top cover 211. Afterwards, the dough is transferred to the screening mechanism 1 via the transfer mechanism 5 for screening. The specific implementation method is as follows: After placing the vent pipe 22 of the fermentation box 2 between two sets of flared baffles 141, the electric transmission wheel 12 is rotated, driving the fermentation box 2 into the area of ​​the shell-removing mechanism 3. During this period, when the limiting baffle 142 guides the vent pipe 22 to move, the lifting rod 131 is activated to lift the lifting plate 133, which in turn drives the lever frame 1421 to lift the limiting baffle 142, causing the limiting baffle 142 to tilt. This allows the fermentation box 2 to gradually skip the limiting baffle 142 and guide the fermentation box. If the length of the vent pipe 22 is insufficient at position 2, it cannot continue to guide the dough, indicating insufficient internal fermentation. The dough then loses the constraint of the limit stop bar 142 and tilts, falling onto the inclined receiving plate 13 below and flowing into the transfer mechanism 5, awaiting further processing. If the length of the vent pipe 22 is longer, when passing through the area of ​​the pressing plate 15, the electric conveyor wheel 12 below the station hall is activated by the pressing lifting rod 152. The pressing plate 15 presses the vent pipe 22 into the inner cavity of the fermentation shell 21, squeezing the dough inside to release air. Simultaneously, the top rod at the end of the guide air pipe 151 presses the pressing ball 23, adds oil to the pressing rod 231, and pushes the sealing plug 233 downwards to overcome the tension of the pressing spring 2331. The gas generated by pressing the dough inside the fermentation shell 21 falls into the guide air pipe 151 after passing through the vent pipe 22. Other sensors detect whether the gas meets the requirements. If it does, the lifting lifting rod 131 is lowered and guided to the shell-removing mechanism 3. If it does not, the lifting lifting rod 131 is raised to cancel the guidance, and the dough falls below the inclined receiving plate 13, thus completing the screening.

[0033] Meanwhile, during the pressing process of the arc-shaped pusher plate, powder, liquid or yeast residue in the fermentation shell 21 will flow out through the vent pipe 22 to the contamination sensor. As the gas flows out through the gap between the fermentation shell 21 and the pressing ball 23, the pocket groove formed by the bent baffle 24 and the inner cavity of the fermentation shell 21 collects the above-mentioned impurities. After completion, they fall into the vent pipe 22. Subsequently, the vent pipe 22 can be cleaned by using air to backwash the vent pipe 22 and the impurities in the vent pipe 22 can be discharged from the vent pipe 22, thus completing the treatment of impurities.

[0034] After falling into the upper area, the dough is guided by the box guide frame 31 and falls between the symmetrical rollers 341. Specifically, the position or width of the box guide frame 31 can be adjusted according to the actual movement rules to ensure that the dough falls between the rollers 341. After falling between the rollers 341, the dough will not slip off due to the overlapping of the skirt on the outer side of the fermentation shell 21. Then, the turntable wheel 361 is rotated. During the rotation of the turntable wheel 361, the turntable wheel 361 moves the fastening plate 26 to pass through the fermentation shell 21. At the same time, the fermentation shell 21 will also clean the dough on the swing rod 36. After completion, the dough will remain sticky inside the fermentation shell 21. At this time, the rotary motor 331 is started to drive the gear receiving plate 33 to rotate. At the same time, the meshing gear 351 moves the fixing rod 35 to rotate, which drives the swing rod 36 to rotate away from the bottom of the fermentation box 2 until the vent pipe 22 points to the push rod lifting rod 362. Then, the rotation of the gear receiving plate 33 is stopped and the push rod lifting rod 362 is started to push the dough. The vent pipe 22 allows the dough to exit the fermentation shell 21. During the start-up of the push rod lifting rod 362, the drive motor 411 is started to rotate the rotating shaft 4111, causing the conveyor belt 44 at the top of the feeding plate 42 to abut against the inner edge of the fermentation shell 21. Under the action of the push rod lifting rod 362, the vent pipe 22 is pushed to allow the dough to exit the fermentation shell 21. Then, the drive motor 411 continues to rotate, using the rotation of the conveyor belt 44 to scrape the dough inside the bending baffle 24. After scraping the entire dough, the roller 341 motor is started to drive the conveyor belt 44 to move, causing the dough to fall onto the surface of the conveyor belt 44 at the outer end of the feeding plate 42. Then, the rotating shaft 4111 is rotated in the opposite direction, using centrifugal force to throw the dough out and collect it. After the dough is collected, the gear receiving tray 33 continues to rotate, causing the vent pipe 22 to face the equipment support surface and fall under the action of gravity to collect the fermentation box 2. After cleaning, it can be re-fermented.

[0035] Because the screening mechanism 1 is relatively tall, in order to facilitate the guidance of the screening mechanism 1 on the fermentation shell 21, after the fermentation box 2 collected by the inclined receiving plate 13 falls into the transverse conveyor belt 51, it can be selected to continue fermentation or process the bad embryos according to different falling conditions. After completion, the fermentation box 2 is manually or mechanically fed back onto the inclined transmission belt 52 and then transported between the threaded conveyor rod 53 and the rotating conveyor rod 55. When the conveyor rod motor 532 is started to rotate the threaded conveyor rod 53, the threaded guide of the threaded conveyor rod 53 guides the fermentation box 2 to move to the vicinity of the screening mechanism 1. Then, under the guidance of the arc-shaped baffle 551, the fermentation box 2 is moved between the flared baffle rod 141, completing the conveying of the fermentation box 2.
