Description

Technical Field

[0001] This invention relates to the field of fermentation equipment technology, and in particular to a dough proofing device with constant temperature and humidity functions. Background Technology

[0002] In the production of dough products such as twisted dough sticks, fermentation is required to improve the sensory quality of the final product. Currently, dough proofing devices are commonly used to promote dough fermentation and proofing. However, traditional equipment usually places the dough statically in a single position for proofing, resulting in insufficient heating at the bottom and uneven temperature and humidity distribution. This problem easily leads to incomplete and uneven proofing of the dough, which in turn affects the quality of the finished product. Therefore, it is necessary to develop a dough proofing device with constant temperature and humidity functions that can maintain a stable temperature and humidity environment during the proofing process to ensure uniform proofing of the dough.

[0003] For example, CN202511059356.7 proposes a dough proofing device with constant temperature and humidity function, including a processing chamber. The top of the processing chamber is equipped with a transparent sealing cover to seal it. A humidifier for humidifying the inside of the processing chamber is installed on the top of the transparent sealing cover, and a thermometer for monitoring the temperature inside the processing chamber is also installed on the top of the transparent sealing cover. A controller for adjusting the data of the humidifier and thermometer is installed outside the processing chamber. The inside of the processing chamber is equipped with a proofing detection mechanism for cutting the dough. This invention, through the cooperation of the proofing detection mechanism, the embedding mechanism, the proofing plate, the cutting knife, the electric hydraulic rod, and the pressure rod, drives the cutting knife to accurately insert into the inside of the dough and cut a slit. It can intuitively present the state of the air pores inside the dough, making it easier for operators to accurately judge the degree of proofing, thereby improving the taste of the finished pasta and reducing the waste of raw materials and cost loss caused by misjudgment. However, it fails to solve the above-mentioned problems.

[0004] The present invention can drive the roller to rotate circumferentially and adjust the pitch angle during the proofing process through a rotating device, so that the dough to be proofed in the roller can be fully turned over, thereby making the dough proof completely and evenly, thus ensuring the quality of the final product.

[0016] Beneficial effects The present invention has the following beneficial effects: (1) This invention completely solves the industry pain point of uneven heating and moisturizing of dough during static proofing, and greatly improves the uniformity of dough proofing and the quality of finished products. The invention achieves bidirectional adjustment of the circumferential rotation and pitch angle of the roller through the rotating device. With the convex blocks and undulating plates inside the roller, the dough is driven to achieve all-round turning and flipping without dead angles, which completely avoids the problem of insufficient heating at the bottom of the dough and incomplete local proofing under the traditional static proofing method. At the same time, the ventilation holes of the roller and the convex blocks can prevent the dough from blocking the ventilation holes, so that the steam can be evenly applied to all surfaces of the dough, ensuring that the proofing degree of each part of the dough is highly consistent, and significantly improving the taste and quality stability of dough products such as twisted dough sticks.

[0017] (2) To achieve precise closed-loop control of constant temperature and humidity in the proofing environment, and to complete the recycling of water vapor, this invention takes into account both proofing stability and energy saving and environmental protection. Through the reflective insulation structure of the insulation shell and the steam centralized guiding design of the guide plate, combined with the real-time feedback control of the detection components and the control panel, the temperature and humidity in the proofing chamber can be precisely maintained. At the same time, the exhaust device efficiently condenses the rising steam through the cooling plate with a special structure. Combined with the flow-guiding structure of the gas collection hood and the opening of the guide plate, the condensate is accurately returned to the evaporation plate for recycling. This not only avoids the problem of excessive humidity caused by excessive steam, but also reduces the loss of water resources and heat energy, and avoids the risk of water accumulation inside the equipment breeding microorganisms and contaminating the dough.

[0018] (3) The equipment operates stably and reliably, and the transmission and adjustment structure is highly adaptable, which greatly reduces the equipment failure rate and maintenance cost. The rotating device of the present invention adopts a spindle-shaped first pulley in conjunction with a tensionable second pulley with a spring. Even when the drum is pitching and swinging, the transmission belt can always be tightly attached to achieve stable transmission without derailment. At the same time, the support roller with spring and the support rod with shock-absorbing spring form a multi-dimensional stable support for the drum, buffering the vibration during rotation and swing. With the sealing ring and shock-absorbing spring between the outer shell and the insulation shell, the sealing and insulation effect of the equipment is guaranteed, and the operating noise and component wear are greatly reduced, effectively extending the service life of the equipment.

[0019] (4) It has strong process adaptability and can flexibly meet diverse proofing needs. It has a wide range of applications. The present invention can flexibly set the core parameters such as proofing temperature, humidity and time through the control panel. The rotation speed and pitch angle of the roller can be adjusted as needed. It can adapt to the proofing process requirements of different formulas and different types of flour products. At the same time, the exhaust device can flexibly realize steam condensation and reflux or forced exhaust according to real-time humidity data. It can not only meet the process requirements of high humidity and slow proofing, but also quickly adjust the internal environment of the cavity to adapt to the needs of large-scale and multi-category flour product production.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1 - Figure 9This invention provides a technical solution: a dough proofing device with constant temperature and humidity function includes a shell 1, an opening at the front end of the shell 1, and a cover plate 2 hinged to the opening. The front end of the cover plate 2 protrudes to fit the opening at the front end of the shell 1 for sealing. A locking component (not shown) is provided on the cover plate 2 and the shell 1 for fixing the cover plate 2. A detection component 33 is provided on the cover plate 2 for detecting temperature and humidity. A control panel 4 is also provided on the shell 1 for controlling the dough proofing device. The device also includes: a fermentation device located inside the shell 1 for heating the dough to improve proofing and fermentation; a rotating device located behind the fermentation device for turning the dough to ensure more even fermentation and control the temperature and humidity of the dough to maintain constant temperature and humidity; and an exhaust device located above the fermentation device to exhaust excess steam, thus maintaining constant temperature and humidity for the dough.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the dough proofing device with constant temperature and humidity function includes a fermentation device, which includes an insulation shell 6, a roller 10, and an evaporation tray 31. The insulation shell 6 is located inside the outer shell 1, and the roller 10 is located inside the insulation shell 6. The inner side of the outer shell 1 is provided with a rubber ring 5 to fit the position of the insulation shell 6. The evaporation tray 31 is installed below the insulation shell 6. The inner side of the insulation shell 6 is made of reflective materials such as aluminum foil to reflect heat and better keep warm. The bottom of the insulation shell 6 is funnel-shaped so that condensate will collect on the evaporation tray 31. The dough is then recycled. The bottom of the insulation shell 6 is provided with guide plates 32 that slope towards the middle on both sides to guide the steam and keep it in the middle so as to better heat the dough. The lower end of the guide plate 32 is provided with an opening for the condensate to flow down. The roller 10 is provided with protrusions 19 and vent holes 20. The vent holes 20 are located in the gaps between the protrusions 19 so that the bottom of the dough can be supported by the protrusions 19, thereby preventing the dough from blocking the vent holes 20, so that the dough can be heated through the vent holes 20.

[0026] In a specific embodiment: When in use, the prepared dough is placed in the drum 10 inside the equipment, and then the cover plate 2 is completely closed to maintain airtightness. Then, the appropriate fermentation parameters are set through the control panel 4, and the evaporation plate 31 is started. The evaporation plate 31 heats the water inside to generate a large amount of steam. The steam is guided by the guide plate 32 inside the equipment and concentrated in the middle area of ​​the drum 10 to form a uniform and humid thermal environment. This process causes the dough to heat up and the humidity to stabilize, thereby efficiently completing the fermentation and proofing, and allowing the dough to fully expand.

[0027] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the dough proofing device with constant temperature and humidity function includes a rotating device, which includes a mounting rod 9, a slide rail 11, a first pulley 12, a motor 13, a second pulley 14, a third pulley 16, a transmission belt 17, a top block 18, a connecting rod 22, a support roller 25, and an electric push rod 34. The mounting rod 9 is rotatably mounted on the insulation shell 6, and the roller 10 is rotatably mounted on the mounting rod 9. The slide rail 11 is fixed to the rear of the insulation shell 6. The rear end of the roller 10 is provided with a ball head structure, and the top block 18 is rotatably mounted on the roller 10 through the ball head structure. The top block 18 is slidably mounted on the slide rail 11. The first pulley 12 is fixed to the rear of the roller 10. The motor 13 is fixed to one side of the insulation shell 6. The second pulley 14 is slidably mounted to the rear of the insulation shell 6. A second spring 15 is provided on the second pulley 14 to connect to the insulation shell 6. The third pulley 16 is rotatably mounted to the rear of the insulation shell 6. The motor 13 drives the first pulley 12 through the transmission belt 17, and the second pulley 14 and the third pulley 16 are kept taut by the transmission belt 17 to ensure stable transmission. The first pulley 12... The belt is spindle-shaped with a larger diameter in the middle and smaller diameters at both ends, keeping the belt in the middle of the first pulley 12 and ensuring that the first pulley 12 can continue to rotate even after a certain amount of torsion. One end of the electric push rod 34 is rotatably mounted inside the insulation shell 6, and the connecting rod 22 is rotatably mounted inside the insulation shell 6. The connecting rod 22 is located on both sides of the roller 10. The upper end of the connecting rod 22 is hinged to the telescopic end of the electric push rod 34. The connecting rod 22 is L-shaped, and a mounting fork 23 is rotatably mounted on the lower end of the connecting rod 22. A rotating shaft 24 is rotatably mounted on the mounting fork 23. A support roller 25 is movably (rotatable and slidable) mounted on the rotating shaft 24. A third spring 26 is provided on both sides of the support roller 25. The support roller 25 is in contact with the front end of the roller 10. The roller 10 is provided with a corresponding sliding groove. A support rod 7 is hinged to the bottom of the roller 10. The support rod 7 is a telescopic rod. A shock-absorbing spring is provided on the support rod 7. The lower end of the support rod 7 is hinged to the heat insulation shell 6. A first spring 8 is provided on the heat insulation shell 6 to connect to the outer shell 1. A wave plate 21 is provided inside the roller 10. The front and rear ends of the heat insulation shell 6 are provided with openings that fit the roller 10.

[0028] In a specific embodiment: during use, the motor 13 is started via the control panel 4, driving the transmission belt 17 to rotate, which in turn drives the first pulley 12 to rotate. The first pulley 12 drives the roller 10 to rotate. The protrusion 19 structure on the inner surface of the roller 10 guides the dough to rotate in the left and right directions. At the same time, the control panel 4 controls the action of the electric push rod 34, pushing the connecting rod 22 to rotate. Then, the pitch angle of the roller 10 is adjusted by the support roller 25 to achieve up and down swinging, driving the dough to roll and tumble in the front and back directions. During this process, the undulating plate 21 assists the dough to fully tumble, thereby ensuring that the steam heat is evenly distributed on the surface of the dough and promoting the uniformity of the dough fermentation process.

[0029] The process of adjusting the pitch angle of the roller 10 is carried out with the mounting rod 9 as the rotation axis. During the process, the support roller 25 slides on the rotating shaft 24 and compresses the third spring 26, so that the support roller 25 always fits against the roller 10 and supports the roller 10.

[0030] like Figure 2 , Figure 3 , Figure 8 and Figure 9 As shown, the dough proofing device with constant temperature and humidity function includes an exhaust device, which includes an exhaust hood 27, a connecting pipe 29, a fan 30, and an exhaust pipe 3. The exhaust hood 27 is fixed to the inner side of the insulation shell 6 and located above the roller 10. A connecting pipe 29 is provided between the exhaust hood 27 and the insulation shell 6. A cooling plate 28 is provided below the exhaust hood 27. The cooling plate 28 is wavy and has a "beaded" structure at its lower edge. The front end of the exhaust hood 27 has an inwardly turned flange. The lower end of the flange is inclined to the rear. The lower side of the rear end of the gas collection hood 27 is provided with a serrated structure. The connecting pipe 29 is a flexible hose. The fan 30 is fixed on the gas collection hood 27 and located at the lower end of the connecting pipe 29. The exhaust pipe 3 is provided on the outer shell 1 and is connected to the connecting pipe 29. The upper end of the exhaust pipe 3 is provided with an arched curved structure so that the condensate generated by the steam at the end of the exhaust pipe 3 can flow out and avoid backflow. The exhaust pipe 3 is provided with a control valve (not shown) to control the airflow discharge.

[0031] In a specific embodiment: the steam from the dough rises to below the gas collecting hood 27 and is dissipated by the cooling plate 28 below the gas collecting hood 27, causing the steam to condense into water droplets. Through the special structure of the lower edge of the cooling plate 28, the water droplets are collected and guided, and then flow to the inside of the gas collecting hood 27 and adhere there. The flange at the front end of the gas collecting hood 27 further guides the flow of water droplets, while the serrated structure at the lower rear end of the gas collecting hood 27 guides the collected water droplets to drip down, so that they fall to the bottom of the insulation shell 6. Subsequently, the water droplets flow into the evaporation plate 31 through the opening at the lower end of the guide plate 32, realizing recycling.

[0032] After the proofing process is completed, the control valve in the exhaust pipe 3 is opened by operating the control panel 4, and the fan 30 is started at the same time to discharge the excess steam.

[0033] Working principle: First, the operator puts the dough to be proofed into the inside of the roller 10, closes the cover plate 2 and fixes it with the locking component to ensure the airtightness between the outer shell 1 and the cover plate 2; then, the operator sets the target temperature, humidity and proofing time parameters through the control panel 4, starts the equipment, and the evaporation plate 31 starts to heat the internal water to generate steam. The steam is guided by the guide plate 32 in the heat preservation shell 6 and concentrated in the middle area of ​​the roller 10. The aluminum foil reflective material on the inside of the heat preservation shell 6 effectively maintains the heat and prevents it from being lost. At the same time, the protrusions 19 on the roller 10 support the dough to prevent the air vents 20 from being blocked, so that the steam can be evenly applied to the surface of the dough through the air vents 20.

[0034] Next, the rotating device is activated: the motor 13 drives the transmission belt 17 to rotate the first pulley 12, causing the roller 10 to rotate around the mounting rod 9, and the protrusion 19 guides the dough to tumble left and right; at the same time, the electric push rod 34 pushes the connecting rod 22 to rotate, the support roller 25 slides along the groove of the roller 10 and compresses the third spring 26, adjusting the pitch angle of the roller 10 to achieve back and forth swinging, and the undulating plate 21 assists in fully turning the dough to ensure that all parts of the dough are evenly heated and moistened. The detection component 33 monitors the internal temperature and humidity in real time and feeds it back to the control panel 4. If the humidity exceeds the standard, the cooling plate 28 of the exhaust device condenses the rising steam, and the water droplets are collected through the "droplet" structure of the cooling plate 28, the flange of the gas collection hood 27 and the serrated structure, and flow back to the evaporation plate 31 for recycling through the opening of the guide plate 32; if the temperature is abnormal, the control panel 4 adjusts the power of the evaporation plate 31 or the working status of the exhaust device.

[0035] Once the dough reaches the set proofing state, the control panel 4 opens the exhaust pipe 3 control valve and starts the fan 30 to expel excess steam, completing the proofing process. Throughout the entire operation, the rubber ring 5 and the first spring 8 between the insulation shell 6 and the outer shell 1 further enhance the sealing and shock absorption effect, ensuring stable operation of the device.
