Description

Technical Field

[0001] This invention relates to the field of dough fermentation technology, and more specifically to a mechanical device for uniform steam distribution in a dough proofing box. Background Technology

[0002] Proofing boxes are used to provide a constant temperature and humidity environment for dough fermentation. Currently, common proofing boxes typically use bottom water tray heating or fixed-position steam nozzles to provide humidity. These methods have the following obvious drawbacks: First, uneven steam distribution is a significant problem. Because the steam is emitted from a fixed point, it is difficult to evenly cover the entire space due to airflow, thermal stratification, and structural limitations within the chamber. This easily leads to temperature differences in different areas (especially the left and right sides or upper and lower layers). This inconsistency in the microenvironment directly causes differences in the metabolic rate and gas production efficiency of yeast in each dough, resulting in inconsistent proofing levels within the same batch of dough. Ultimately, this directly affects the uniformity of the final product's texture, volume, and flavor. Secondly, the function of key components is not guaranteed. In order to achieve gentle and uniform steam diffusion, some equipment will set a steam diffusion net at the steam outlet. The main function of this core component is to disperse the concentrated steam flow and send it out evenly in a diffused and surface form, rather than simply filtering. However, in a long-term high temperature and high humidity environment, this diffusion net is easily attached and blocked by scale or flour particles floating in the environment, causing it to fail. This destroys the stable humidity field that maintains the optimal activity of yeast, resulting in uneven distribution of internal steam, making it impossible for the yeast fermentation process to be predictable and repeatable under the predetermined conditions. Finally, the inner wall is difficult to clean and maintain. During the proofing process, impurities carried by steam are easily condensed and hardened on the inner wall of the box, forming a dead corner for hygiene. Manual cleaning is costly and affects the continuity of production. These hard-to-clean residues may become a breeding ground for mold and bacteria, contaminating subsequent batches of dough. Bacteria not only compete with yeast for nutrients, but their metabolites may also introduce unpleasant sour tastes or inhibit yeast activity, seriously affecting the purity of fermentation flavor and product quality and safety. Therefore, there is an urgent need for a mechanical device for uniformly distributing steam in a pastry proofing box to solve the aforementioned technical problems. Summary of the Invention

When each set of second electrically controlled push rods is activated, it can drive the corresponding electromagnetic block to move into the interior of the corresponding magnetic suction slot.

[0006] Preferably, a fixing plate is installed on the bottom surface of the auxiliary slider, and a motor is installed inside the fixing plate. An electrically controlled lifting rod is installed at the drive end of the motor. The bottom of the electrically controlled lifting rod is fixed to the middle area of ​​the upper surface of the conveying device. Diffuser nets are installed inside both sides of the upper surface of the conveying device.

[0007] Preferably, the lifting end of the diffuser is equipped with a frame plate, wherein a first torsion spring is installed on the inner wall of both sides of the frame plate, and the same scraper plate is installed on the end of each set of first torsion springs away from the frame plate. A rubber ring plate is installed through the bottom inner wall of the scraper plate near the conveying device. An inclined surface is opened on the inner wall of the side of the rubber ring plate away from the frame plate. Multiple sets of air outlets are opened on the scraper plate near the corresponding inclined surface. Countersunk grooves are opened inside the top two sides of the conveying device.

[0008] Preferably, the inner side of the countersunk groove is adapted to the outer side of the rubber annular plate, wherein a second torsion spring is installed on the inner wall of both sides of the countersunk groove, and the end of the second torsion spring away from the countersunk groove is equipped with the same sealing plate. Conveying grooves are installed on the inner wall of both sides of the conveying device, and the conveying grooves are connected to the countersunk groove. A steam generator and a compressed air compressor are installed sequentially on the back of the proofing box, with the output ends of the steam generator and the compressed air compressor connected by the same delivery pipe.

[0009] Preferably, a conveying hose is installed in the middle of the conveying pipe, and two sets of air outlets are provided at the end of the conveying hose away from the conveying pipe. Each set of air outlets is respectively set inside the two sets of conveying troughs. A pressure sensor is installed inside the steam generator to collect the air pressure data inside the conveying pipe and transmit it to the control module to determine whether the diffuser is blocked. Multiple sets of card plate assemblies are installed at equal intervals inside the proofing box.

[0010] Preferably, each set of card plate assemblies includes an upper card plate and a lower card plate, wherein there is a clamping space between two adjacent sets of upper card plates and lower card plates for fixing the dough placement plate. The top of the card plate assembly is provided with a collection groove, wherein the upper card plate is provided with a recycling chamber, and the card plate is provided with an adsorption hole on the inner wall near the collection groove, and the adsorption hole and the recycling chamber are mutually circulated. Both sides of the proofing box are equipped with impurity recovery devices. The output end of the impurity recovery device is equipped with a porous tube, which includes multiple sets of auxiliary recovery ends. Each set of recovery ends is sequentially arranged inside the corresponding recovery chamber. The proofing box has receiving slots installed on both inner walls near the top set of card plate assemblies, and an electrically controlled door is installed on the side of the receiving slots near the inside of the proofing box.

[0011] Preferably, the auxiliary detection mechanism includes a first electrically controlled push rod, a protective plate is provided on the other side of the receiving slot, the first electrically controlled push rod is installed at the end of the protective plate away from the electrically controlled door, the first electrically controlled push rod is installed on the outer side of the proofing box, the inner side of one side of the protective plate is adapted to the diffuser net, the bottom of the protective plate is adapted to the upper surface of a corresponding set of upper card plates, and a recycling slot is opened inside the bottom end of the protective plate.

[0012] The technical effects and advantages of this invention are as follows: This invention utilizes temperature sensors located on both sides of the proofing box to monitor the temperature distribution inside in real time. The control module automatically adjusts the horizontal position of the movable conveyor device based on the temperature difference between the two sides, allowing steam to be delivered selectively and adjustably to areas with lower temperature and humidity. This effectively improves the uniformity of temperature and humidity throughout the proofing box, creating a highly consistent metabolic environment for the yeast community within all dough particles. This fundamentally ensures the synchronization of fermentation rate and gas production efficiency, achieving uniform proofing of dough from the same batch, and ultimately improving the consistency of the product's texture and volume.

[0013] This invention monitors pressure changes using a pressure sensor in the steam pipeline, intelligently determining whether the diffuser is clogged. When an anomaly is detected, the control module automatically initiates a cleaning program, using compressed air and airflow generated by the impurity recovery device to purge the diffuser in both directions, effectively removing attached scale and flour particles. This function ensures that the diffuser continuously and stably plays its core role in uniformly diffusing steam, maintaining a stable and unfluctuating ideal humidity field inside the chamber. It avoids stress on yeast activity caused by uneven or interrupted humidity supply, ensuring that the fermentation process is predictable and repeatable.

[0014] This invention controls the conveying device to move to the vicinity of the inner wall of the box through a drive mechanism, and uses a combination of deployable scraper and compressed air jet to automatically scrape and remove the hardened impurities that have condensed on the box wall. The cleaned impurities are collected and recycled through a negative pressure adsorption system. This automated cleaning mechanism greatly reduces hygiene dead spots and manual intervention, effectively eliminating the risk of the growth of miscellaneous bacteria (such as lactic acid bacteria and acetic acid bacteria) due to dirt accumulation, thereby maintaining the biological purity of the fermentation microenvironment, preventing miscellaneous bacteria from competing with yeast for nutrients or producing harmful metabolites, and ensuring the purity of the fermented dough flavor and the safe and stable production of the product.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The steam uniform distribution mechanical device for a pastry proofing box involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Reference Figures 1 to 8As shown, the present invention provides a mechanical device for uniform steam distribution in a pastry proofing box, including a proofing box 1 and an auxiliary detection mechanism 3. A sealing door is provided at the front end of the proofing box 1, wherein temperature sensors are installed on both sides of the sealing door near the proofing box 1 to collect temperature data on both sides inside the proofing box 1 and transmit it to a control module provided inside the proofing box 1 to help determine whether the steam distribution in the proofing box 1 is uniform. The auxiliary detection mechanism 3 includes a first electrically controlled push rod 301. The inner wall of the top of the proofing box 1 is provided with a T-shaped slide groove 104. An auxiliary slider 403 is movably adjusted to fit the inner wall of the T-shaped slide groove 104. A drive mechanism is provided inside the T-shaped slide groove 104 to drive the auxiliary slider 403 to slide inside the T-shaped slide groove 104. An active detection and cleaning component 4 is provided at the bottom of the auxiliary slider 403. The active detection and cleaning component 4 also includes a conveying device 401. The inner walls of the bottom sides of the conveying device 401 are magnetically attached to diffuser nets 409, which are used to evenly disperse the outflowing steam. The control module controls the drive mechanism to adjust the position of the auxiliary slider 403 and the conveying device 401 according to the temperature data on both sides, so that the conveying device 401 can evenly diffuse the steam inside to the interior of the proofing box 1. The top of the conveying device 401 is provided with a scraper 402, which performs scraping operation on the interior of the proofing box 1 under the action of the auxiliary slider 403 and the drive mechanism.

[0019] In this embodiment of the application, the magnetic attraction force generated between each set of magnetic slots 404 and electromagnetic blocks 407 is sufficient to support the second electronically controlled push rod 408 to control the auxiliary slider 403 to slide left and right. The temperature sensor model is TFD-901. Its core principle is based on the resistance effect of conductors such as platinum and copper, that is, their resistance value will increase regularly as the temperature rises. The sensor monitors this resistance change in real time through internal measurement circuits such as Wheatstone bridges and converts it into a standard electrical signal, which is then transmitted to the control module for calculation to obtain accurate temperature data.

[0020] The control module has an internal temperature threshold range set as the optimal temperature range for dough proofing. This range is manually set. The control module compares two sets of temperature data collected by the temperature sensor with the temperature threshold range in real time. If both sets of real-time temperature data are below the temperature threshold range, the output steam volume and temperature of the conveying device 401 are increased. If both sets of real-time temperature data are above the temperature threshold range, the output steam volume and temperature of the conveying device 401 are decreased. If one set of real-time temperature data is below the temperature threshold range, the control module controls the conveying device 401 to move to that position.

[0021] The driving mechanism includes magnetic suction slots 404 opened on three adjacent sides of the auxiliary slider 403, electromagnetic blocks 407 adapted thereto, and three sets of second electric push rods 408. Each set of electromagnetic blocks 407 is sequentially installed on the lifting end of the corresponding second electric push rod 408. All three sets of second electric push rods 408 are installed inside the proofing box 1. When each set of second electric push rods 408 is activated, it can drive the corresponding electromagnetic block 407 to move into the interior of the corresponding magnetic suction slot 404. Each set of magnetic slots 404 and electromagnetic blocks 407 will generate a magnetic attraction force, the strength of which is sufficient to support the second electronically controlled push rod 408 to drive the auxiliary slider 403 to move within the inner wall of the T-shaped slide 104.

[0022] Reference Figures 1 to 13 As shown, the present invention provides a mechanical device for uniform steam distribution in a pastry proofing box. A fixing plate 405 is installed on the bottom surface of the auxiliary slider 403. A motor is installed inside the fixing plate 405. An electrically controlled lifting rod 406 is installed on the transmission end of the motor. The bottom of the electrically controlled lifting rod 406 is fixed to the middle area of ​​the upper surface of the conveying device 401. Both sides of the upper surface of the conveying device 401 are equipped with a diffuser net 409. The lifting end of the diffuser net 409 is equipped with a frame plate 410. The inner walls of both sides of the frame plate 410 are equipped with a first torsion spring 413. The end of each set of first torsion springs 413 away from the frame plate 410 is equipped with the same scraper plate 402. The scraper plate 402 has a rubber ring plate 411 installed through it on the bottom inner wall near the conveying device 401. The inner wall of the rubber ring plate 411 away from the frame plate 410 has an inclined surface. The scraper plate 402 has multiple sets of air outlets near the corresponding inclined surface. In this embodiment, the diffuser 409 is activated, driving the frame plate 410 and the scraper plate 402 to move away from the conveying device 401. When the bottom of the scraper plate 402 moves to the top position of the conveying device 401, under the action of the torsion spring force preset by the first torsion spring 413, each set of scraper plates 402 is controlled to be perpendicular to both sides of the top of the conveying device 401 in sequence. At this time, the direction of the air outlet on each set of scraper plates 402 is facing.

[0023] The top two sides of the conveying device 401 are provided with countersunk grooves. The inner side of the countersunk groove is adapted to the outer side of the rubber ring plate 411. The inner walls of both sides of the countersunk groove are equipped with second torsion springs 414. The end of the second torsion spring 414 away from the countersunk groove is equipped with the same sealing plate 412. The inner walls of both sides of the conveying device 401 are equipped with conveying grooves 415, which are connected to the countersunk grooves. In this embodiment of the application, the installation position of the diffuser 409 is close to the conveying trough 415, wherein the diffuser 409 and the conveying trough 415 are connected.

[0024] A steam generator 5 and a compressed air machine 6 are installed sequentially on the back of the proofing box 1. The output ends of the steam generator 5 and the compressed air machine 6 are connected to the same delivery pipe 7. A delivery hose 701 is installed in the middle of the delivery pipe 7. The end of the delivery hose 701 away from the delivery pipe 7 is provided with two sets of air outlets. Each set of air outlets is respectively located inside the two sets of delivery troughs 415. The steam generator 5 is equipped with a pressure sensor to collect the air pressure data inside the delivery pipe 7 and transmit it to the control module to determine whether the diffuser net 409 is blocked.

[0025] In this embodiment of the application, the control module has a pre-stored air pressure threshold range, which is statistically derived from the pressure data collected by the pressure sensor installed on the conveying device 401 or the steam pipeline under normal working conditions of the diffuser network 409. When the system is running, the control module compares the real-time pressure data collected by the pressure sensor with the preset air pressure threshold range: If the real-time pressure data continues to be higher than the upper limit of the threshold range, it is determined that the diffuser 409 is blocked, and the control module can trigger the cleaning mode and record the fault. If the real-time pressure data continues to be below the lower limit of the threshold range, it is determined that the diffuser net 409 may be damaged or detached, and the control module issues an emergency warning signal through the sound reminder device set on the top of the waking box 1.

[0026] The interior of the proofing box 1 is equipped with multiple sets of card plate assemblies 101 at equal intervals. Each set of card plate assemblies 101 includes an upper card plate 1011 and a lower card plate 1012. There is a clamping space between two adjacent sets of upper card plates 1011 and lower card plates 1012 for fixing the dough placement plate. The top of the card plate assembly 101 is provided with a collection groove 1013. The upper card plate 1011 is provided with a recycling chamber. The card plate 1011 is provided with an adsorption hole 1014 on the inner wall near the collection groove 1013. The adsorption hole 1014 and the recycling chamber are mutually circulated. Both sides of the proofing box 1 are equipped with impurity recovery devices 2. The output end of the impurity recovery device 2 is equipped with a porous tube 201. The porous tube 201 includes multiple sets of auxiliary recovery ends, and each set of recovery ends is arranged in sequence inside the corresponding recovery chamber. The proofing box 1 has receiving slots 103 installed on both inner walls near the top set of card plate assemblies 101. An electrically controlled door 102 is installed on one side of the receiving slot 103 near the inside of the proofing box 1, and a protective plate 302 is provided on the other side of the receiving slot 103. A first electrically controlled push rod 301 is installed on one end of the protective plate 302 away from the electrically controlled door 102. The first electrically controlled push rod 301 is installed on the outer side of the proofing box 1. The inner side of one side of the protective plate 302 is adapted to the diffuser net 409. The bottom of the protective plate 302 is adapted to the upper surface of the corresponding set of upper card plates 1011. A recycling slot 3021 is opened inside the bottom end of the protective plate 302.

[0027] The model number of the barometric pressure sensor is FMTKSG.

[0028] The specific workflow for this application is as follows: Step 1: A measured amount of yeast is placed inside the dough. The dough is then manually moved to the placement board, which is then moved into the clamping space formed by the upper clamping plate 1011 and the lower clamping plate 1012 of each set. After placement, the proofing box 1 is started to proof the dough inside the proofing box 1. Step 2: The steam generator 5 is started, generating steam at a preset temperature and transmitting it through the conveying pipe 7 and the conveying hose 701 to the inside of the conveying tank 415. The steam inside the conveying tank 415 is evenly dispersed into the inside of the proofing box 1 by the action of each set of diffuser nets 409. Step 3: The control module simultaneously monitors the steam distribution inside the proofing box 1 using real-time temperature data generated by the temperature sensor. If both sets of real-time temperature data are below the temperature threshold range, the output steam quantity and temperature of the conveying device 401 are increased. If both sets of real-time temperature data are above the temperature threshold range, the output steam quantity and temperature of the conveying device 401 are decreased. If one set of real-time temperature data is below the temperature threshold range, the control module activates the second electric control push rod 408 and the electromagnetic block 407 on that side. The second electric control push rod 408 controls the electromagnetic block 407 to move into the magnetic suction groove 404, so that a magnetic attraction force is generated between the electromagnetic block 407 and the magnetic suction groove 404. At the same time, the second electric control push rod 408 drives the auxiliary slider 403 and the conveying device 401 to move to that side to facilitate adjustment of the steam spray position. Step 4: The control module triggers the cleaning mode. A set of first electrically controlled push rods 301 and electrically controlled doors 102 are activated. The first electrically controlled push rods 301 control the protective plate 302 to move to the top of the corresponding upper plate 1011. At the same time, the drive mechanism and electrically controlled lifting rod 406 are activated, controlling the diffuser net 409 on one side of the conveying device 401 to move to the inner side of the set of protective plates 302. Simultaneously, the compressed air compressor 6 is activated, generating compressed air that moves through a set of air outlets of the conveying pipe 7 and the conveying hose 701 to the inside of the conveying trough 415 near the set of diffuser nets 409. At the same time, the impurity recovery device 2 is activated. Adsorbed gas is generated and transported through porous tube 201 to the recovery chamber of the corresponding upper plate 1011, and then transported through collection tank 1013 to the outer surface of the diffuser net 409. Under the action of the circulating cleaning airflow generated by the corresponding compressed air and adsorbed gas, the diffuser net 409 is cleaned. The above steps are repeated to clean another set of diffuser nets 409. After cleaning is completed, the control module performs a second detection on the diffuser net 409. If the control module triggers the cleaning simulation again, the control module issues an emergency warning signal through the sound reminder device set on the top of the waking box 1. Step 5: The motors inside the drive mechanism, the electrically controlled lifting rod 406, and the fixed plate 405 are started, controlling the conveyor 401 to move to the inner wall of the corresponding proofing box 1 to be cleaned. The diffuser 409 is activated, driving the frame plate 410 and the scraper 402 to move away from the conveyor 401. When the bottom of the scraper 402 moves to the top position of the conveyor 401, under the action of the torsion spring force preset by the first torsion spring 413, each set of scraper 402 is controlled to be perpendicular to both sides of the top of the conveyor 401. At this time, the air outlets on each set of scraper 402 are facing the same direction. At this time, the rubber ring plate 411 is pressed against the corresponding sealing plate 412, controlling the sealing plate 412 to be in the open state. Simultaneously, the air compressor 6 starts, generating compressed air that moves through a set of air outlets of the conveying pipe 7 and the conveying hose 701 to the interior of the corresponding conveying trough 415. Part of the compressed air inside the conveying trough 415 passes through the interior of the corresponding countersunk groove, the rubber annular plate 411, and the scraping plate 402, and is transmitted to the inner wall of the proofing box 1 to be cleaned through the air outlet on the side of the conveying device 401. Under the scraping action of the scraping plate 402 and the compressed air in the air outlet, the inner wall of the proofing box 1 is scraped and cleaned. The cleaned impurities flow into the interior of the corresponding collection trough 1013. At the same time, the impurity recovery device 2 starts, and the first electrically controlled push rod 301 recovers the remaining impurities inside the collection trough 1013.

[0029] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
