Description

Technical Field

[0001] This application relates to the technical field of proofing dough products, and in particular to a circulating air guiding structure inside a proofing box for dough products. Background Technology

[0002] Pastries are a type of food made primarily from flour or rice flour, sugar, oil, eggs, and dairy products, along with various auxiliary ingredients, fillings, and seasonings. After initial shaping, they are processed through methods such as steaming, baking, frying, and stir-frying. Before processing, the dough needs to undergo a proofing process. Proofing refers to letting the kneaded dough rest for a period of time before further processing or cooking. This process makes the kneaded dough easier to process, resulting in pastries that are more elastic, softer, and have a more delicate and smooth texture. In food processing and research, dough proofing boxes are used to proof the dough.

[0003] Currently, most food processing plants use proofing boxes to proof dough. These boxes are typically made of stainless steel. They allow dough placed inside to proof quickly through heating and humidification. An opening on one side of the box houses a hinged door. When proofing is needed, workers open the door, place the dough inside, and remove it after proofing, completing one proofing cycle.

[0004] Microorganisms are crucial for the transformation of dough during fermentation. Microorganisms require suitable temperature, humidity, and oxygen concentration to grow and metabolize. Ventilation provides sufficient oxygen and alters the humidity and carbon dioxide concentration in the air, allowing microorganisms to carry out their metabolic activities smoothly. Furthermore, the fermentation process generates a large amount of heat and gases, such as carbon dioxide and ethanol; ventilation removes this heat and waste gases, maintaining a suitable temperature and humidity environment and preventing adverse effects on microorganisms.

[0005] Existing proofing boxes are usually equipped with blowers that blow air into the box to promote the proofing of dough. However, the box structure is usually large, and a single blower cannot deliver air to all parts of the dough during proofing. The proofing time of dough located near the air vent and dough located far away from the air vent often differs significantly. Utility Model Content

[0006] In order to improve the proofing efficiency of dough and ensure that the dough is not affected by the heat and gas generated during the proofing process, this application provides a circulating airflow structure inside the proofing box for dough products.

[0007] This application provides a circulating airflow guiding structure for a dough product proofing box, which adopts the following technical solution:

[0008] A circulating airflow structure for a dough product proofing box includes a proofing box with a hollow interior and an opening on one side, a door rotatably mounted at the opening of the proofing box, and an air supply device mounted on the proofing box. The air supply device includes an air supply duct connected to the interior of the proofing box. The interior of the proofing box also includes a flow guide assembly, which includes a flow guide plate mounted on the inner wall of the proofing box. A flow guide duct for airflow is provided between the flow guide plate and the inner wall of the proofing box. Air blown into the proofing box through the air supply duct can blow onto the flow guide plate and enter the flow guide duct.

[0009] By adopting the above technical solution, the dough to be proofed is placed inside the proofing box. During the proofing process, the air supply device delivers air into the proofing box through the air supply duct. The air entering the proofing box can be blown onto the guide plate and flow into the guide air duct. As the air flows inside the proofing box, it can carry away the heat and carbon dioxide gas generated during the proofing process, thereby ensuring that the inside of the proofing box is always in the optimal environment for dough proofing, thus improving the proofing efficiency of the dough.

[0010] Preferably, the air supply duct is connected to the side wall of one side of the proofing box, and a pair of guide plates are provided inside the proofing box. The two guide plates are installed on the upper and lower inner walls of the proofing box, and the two guide plates are symmetrically arranged above and below the opening of the air supply duct, so that the dough to be proofed can be placed on the lower guide plate.

[0011] By adopting the above technical solution, the air guide plates set on the upper and lower sides of the proofing box can blow the air delivered to the proofing box onto the two air guide plates, so that the air flows on the upper and lower sides of the proofing box and along the air guide channel. Guided by the two air guide plates, the air flows from one end of the proofing box to the other end, realizing the air flow and allowing the heat and gas generated by the dough fermentation to be carried away more quickly.

[0012] Preferably, the proofing box is also equipped with an exhaust device, which includes an exhaust duct connected to the inside of the proofing box, and the air supply duct and the exhaust duct are symmetrically arranged at both ends of the guide plate.

[0013] By adopting the above technical solution, the air that carries away heat and gas inside the proofing box can be quickly drawn away by the exhaust device, increasing the airflow speed and allowing the heat and gas to be quickly discharged from the proofing box.

[0014] Preferably, the guide plate has symmetrically arranged air guide plates at both ends, and the air guide plates are inclined toward the corresponding air supply pipe or exhaust pipe.

[0015] By adopting the above technical solution, the air guide plate plays a role in guiding the air, allowing the air blown out from the air supply duct to flow better along the air guide plate and onto the guide plate, preventing the air entering the proofing box from flowing randomly.

[0016] Preferably, a V-shaped air guide plate is installed on the inner wall of the end of the air supply duct near the inside of the proofing box, and the V-shaped opening of the air guide plate faces the ends of the two air inlet plates.

[0017] By adopting the above technical solution, the air guide plate set inside the air supply duct can form two upward and downward inclined air outlets at the duct opening. When the air in the air supply duct is blown out through the air guide plate, it can be blown into the upper and lower air guide channels of the proofing box and circulate along the inner wall. The air flow reduces the temperature in the proofing box or removes the gas generated during dough proofing, thus ensuring that the inside of the proofing box is always in a better proofing environment.

[0018] Preferably, the proofing box is further provided with a control device for controlling the air intake volume of the air supply duct and the air exhaust volume of the air exhaust duct. The control device includes an air supply baffle that is slidably inserted into the air supply duct and an air exhaust baffle that is slidably inserted into the air exhaust duct. The air supply baffle and the air exhaust baffle control the opening and closing degree of the air supply duct and the air exhaust duct, respectively.

[0019] By adopting the above technical solution, all the air output by the air supply device is delivered to the proofing box, which may cause a large amount of air to flow into the proofing box in a short period of time. Therefore, the air supply baffle can dynamically control the opening degree of the air supply duct to adjust the air volume delivered to the proofing box. Correspondingly, the exhaust baffle is used to control the opening degree of the exhaust duct, so that the inside of the proofing box can be in a state of dynamic air volume balance, and avoid the air volume extracted from the proofing box being greater than the air volume delivered to the proofing box.

[0020] Preferably, the control device further includes a linkage component for controlling the synchronous sliding of the air supply baffle and the exhaust baffle, the linkage component including a linkage rod connecting the air supply baffle and the exhaust baffle.

[0021] By adopting the above technical solution, when it is necessary to control the air volume delivered to the proofing box, the staff pulls the linkage rod to simultaneously control the movement of the air supply baffle and the exhaust baffle, so that the air supply duct and the exhaust duct open to the appropriate size, and control the air intake and exhaust volume to maintain a balance.

[0022] Preferably, the linkage assembly includes a limiting rod disposed on the linkage rod, the limiting rod passing through the linkage rod and vertically fixed to the proofing box, the limiting rod being provided with threads, and a limiting nut being threadedly connected to the limiting rod, the limiting nut abutting against the linkage rod and restricting the continued movement of the linkage rod.

[0023] By adopting the above technical solution, when the linkage rod is pulled to the designated position, the limiting nut is rotated and pressed against the linkage rod to prevent the linkage rod from sliding, thereby fixing the position of the linkage rod on the limiting rod.

[0024] Preferably, the air supply device further includes a blower disposed on the proofing box and supplying air inside the proofing box, and a purification heating component connected to the blower. The purification heating component includes a purification box communicating with the blower, and a purification plate and a heating plate inserted into the purification box. The purification plate is installed between the heating plate and the blower.

[0025] By adopting the above technical solution, the air delivered by the blower to the proofing box can first be delivered to the purification box, where it is filtered and purified by the purification plate to remove impurities and dust from the air and prevent them from being blown into the proofing box. When the temperature in the proofing box is low, a heating plate can be inserted into the purification box to heat the purified and filtered air. The heated air is then delivered to the proofing box to increase the temperature required for proofing the dough, thereby improving the efficiency of dough proofing.

[0026] Preferably, the exhaust device further includes an exhaust fan installed on the proofing box, and the exhaust fan is connected to an exhaust duct.

[0027] By adopting the above technical solution, the exhaust fan can quickly extract the heat and gas generated during dough proofing through each exhaust pipe, preventing them from accumulating inside the proofing box and promoting air circulation inside the proofing box.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. During the proofing process of the dough, a large amount of heat and carbon dioxide gas are generated and accumulate in the proofing box. The blower can deliver a large amount of air into the proofing box. The air can be filtered and purified or heated by the purification heating component to deliver clean air into the proofing box. The air entering the proofing box can be blown into the upper and lower air ducts, allowing the air to circulate in the proofing box. During the air circulation, the heat and carbon dioxide gas generated during the dough proofing can be carried away and discharged to the outdoor environment by the exhaust fan, so that the inside of the proofing box is always in the best environment for dough proofing.

[0030] 2. The required airflow into the proofing box is delivered through the air supply duct. This can cause all the airflow generated by the air supply frame to be delivered into the proofing box, resulting in a significant drop in temperature and hindering the proofing of the dough. Therefore, by setting up air supply baffles and exhaust baffles, the size of the opening inside the air supply duct is controlled to control the amount of air delivered. The exhaust baffle is also controlled to open to the same size synchronously by a linkage rod to achieve a balance between airflow in and out. Attached Figure Description

[0039] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0040] This application discloses a circulating airflow guide structure for a dough product proofing box.

[0041] Reference Figure 1 A circulating airflow structure for a dough proofing box 1 includes a proofing box 1 with a hollow internal structure for placing dough to be proofed. An opening is provided on one side of the proofing box 1, and a downward-opening door 11 is provided at the opening. The door 11 can be opened from a vertical position to a horizontal position, making it convenient for workers to take dough into the proofing box 1. A heating device to increase the internal temperature of the proofing box 1 and a humidifying device to increase the internal humidity of the proofing box 1 are provided inside the proofing box 1. The environment inside the proofing box 1 is improved by the two sets of devices, thereby improving the efficiency of dough proofing. An air supply device 2 is installed on the proofing box 1 to supply air into it, and an airflow guide component 4 is installed inside the proofing box 1 to supply air circulation. An exhaust device 3 is installed on the proofing box 1 on the other side opposite to the air supply device 2. When proofing dough, the worker places the dough to be proofed into the proofing box 1. The air supply device 2 supplies the air volume required for proofing into the proofing box 1. The airflow guide component 4 allows the air to circulate inside the proofing box 1. The airflow, along with heat and carbon dioxide gas, can be extracted through the exhaust device 3, thereby allowing the air to circulate inside the proofing box 1 and preventing the heat and carbon dioxide gas generated during dough proofing from not being able to escape from the proofing box 1.

[0042] The proofing box 1 has a rectangular structure, and multiple proofing boxes 1 are stacked vertically to form a large proofing box 1 structure. The multiple proofing boxes 1 are fixed to each other. The air supply device 2 and the exhaust device 3 are set on both sides of the multiple proofing boxes 1. The multiple independent proofing boxes 1 can place the dough to be proofed in each proofing box 1 during the proofing process, so that dough of different weights can be placed in different proofing boxes 1 for proofing. This avoids the need to frequently open the box door 11 of the proofing box 1 due to different proofing times, which would make the environment inside the proofing box 1 unfavorable for the proofing of the dough. Multiple sets of flow guiding components 4 are also provided, and each proofing box 1 has a corresponding flow guiding component 4. A base is set under the bottom layer of proofing boxes 1, and multiple proofing boxes 1 are installed on the base.

[0043] Reference Figure 1 and Figure 2 The air supply device 2 includes a blower 21 mounted on the uppermost proofing box 1 and air supply ducts 22 connecting to the interior of each proofing box 1. The air supply ducts 22 are fixed to the ends of each proofing box 1. A main air supply pipe 23, connected to each air supply duct 22, is fixed to the ends of the multiple air supply ducts 22 away from the proofing box 1. The main air supply pipe 23 is arranged vertically. A connecting pipe 24 is provided between the upper end of the main air supply pipe 23 and the air outlet of the blower 21. The air output by the blower 21 is transported to the main air supply pipe 23 through the connecting pipe 24 and then distributed to each air supply duct 22. A purification heating assembly 25 is mounted on the connecting pipe 24, which includes a purification box 251 connected to the connecting pipe 24. The structure is hollow inside. A purification plate 252 and a heating plate 253 are slidably inserted into the purification box 251. The length direction of the connecting pipe 24 is perpendicular to the purification plate 252 and the heating plate 253. The purification plate 252 is located between the heating plate 253 and the blower 21. The air delivered to the purification box 251 by the blower 21 can be purified by passing through the purification plate 252 to remove impurities and dust from the air and prevent them from being blown into the proofing box 1. When the temperature in the proofing box 1 is low, the heating plate 253 can be inserted into the purification box 251 to heat the purified and filtered air. The heated air is then delivered to the proofing box 1 to increase the temperature required for proofing the dough, thereby improving the efficiency of dough proofing.

[0044] Reference Figure 2 and Figure 3The air supply duct 22 consists of an inclined section and a horizontal section, and the cross-section of the air supply duct 22 is rectangular. The inclined section of the air supply duct 22 is connected and fixed to the main air supply duct 23, and the horizontal section of the air supply duct 22 is connected and fixed to the proofing box 1. The inclined sections of multiple air supply ducts 22 are arranged parallel to each other. After the blower 21 delivers air into the main air supply duct 23, the air blows from the upper end to the lower end of the main air supply duct 23. The inclined air supply duct 22 can make the air blow more smoothly into each air supply duct 22, thereby allowing the air to blow into each proofing box 1. Inside the main air supply duct 23 and at the opening of each air supply pipe 22, a guide element 26 is rotatably installed. The guide element 26 includes a guide shaft 261 rotatably installed on the inner wall of the main air supply duct 23 and multiple guide blades 262 fixed on the guide shaft 261. The multiple guide blades 262 are evenly distributed circumferentially along the axis of the guide shaft 261. When ventilation is carried out in the main air supply duct 23, the wind blows the guide element 26 to rotate, which can better allow the air to enter the air supply pipe and allow the air to continue to flow along the main air supply duct 23 so that it can flow to the next air supply pipe 22.

[0045] A V-shaped air guide plate 27 is fixed on the inner wall of the end of each air supply duct 22 located inside the proofing box 1. The V-shaped tip of the air guide plate 27 is set away from the proofing box 1, and the V-shaped air guide plate 27 forms two upward and downward inclined air outlets at the opening of the air supply duct 22. When the air in the air supply duct 22 is blown out through the air guide plate 27, it can blow towards the upper and lower inner walls of the proofing box 1 and circulate along the inner wall. The air flow reduces the temperature in the proofing box 1 or removes the gas generated during dough proofing, preventing the air from blowing directly onto the dough and causing the surface of the dough to dry and crack.

[0046] Reference Figure 2 and Figure 3 The exhaust device 3 includes an exhaust fan 31 installed on the uppermost proofing box 1 and exhaust ducts 32 connected to each proofing box 1. The exhaust ducts 32 are located at one end of the proofing box 1 relative to the air supply duct 22. The ends of the multiple exhaust ducts 32 away from the proofing box 1 are connected to a vertically arranged main exhaust pipe 33. The upper end of the main exhaust pipe 33 is connected to the exhaust port of the exhaust fan 31. The exhaust fan 31 can extract the heat and gas generated during dough proofing through each exhaust duct 32 to prevent them from accumulating inside the proofing box 1. The exhaust device 3 and the air supply device 2 are arranged in cooperation with each other. The air supplied by the air supply device 2 into the proofing box 1 can be extracted by the exhaust device 3 after flowing inside the proofing box 1, thereby allowing the heat and gas inside the proofing box 1 to be quickly discharged and promoting the circulation of air inside the proofing box 1.

[0047] The airflow guiding assembly 4 includes a pair of airflow guiding plates 41 installed on the upper and lower inner walls of the proofing box 1. The length direction of the airflow guiding plates 41 is the same as the length direction of the proofing box 1, and the two ends of the airflow guiding plates 41 point towards the air supply duct 22 and the exhaust duct 32. Multiple fixing blocks are fixed on the airflow guiding plates 41 and fixed to the inner wall of the proofing box 1. The fixing blocks fix the airflow guiding plates 41 to the inner wall of the proofing box 1, thereby forming an airflow guiding channel 42 between the airflow guiding plates 41 and the inner wall of the proofing box 1. The air blown into the proofing box 1 can flow in the upper and lower airflow guiding channels 42, thereby allowing the air to flow from one direction to another in the proofing box 1. During the airflow process, the heat and gas generated by the dough fermentation are carried away. In addition, the airflow is prevented from blowing directly onto the surface of the dough, preventing the surface of the dough from drying and cracking. When the dough needs to be proofed, the worker can place the dough on the lower airflow guiding plate 41 for proofing.

[0048] Reference Figure 2 and Figure 3 A symmetrically arranged inclined air guide plate 43 is provided at both ends of the guide plate 41. The air guide plate 43 extends towards the corresponding air supply duct 22 or exhaust duct 32. The air blown out from the air supply duct 22 can flow better along the air guide plate 43 to the guide plate 41, preventing the air entering the proofing box 1 from flowing randomly. The air flows from the air supply duct 22 through the guide air duct 42 to the exhaust air duct 32, and is then extracted from the proofing box 1 through the exhaust air duct 32, ensuring that clean air always flows into the proofing box 1.

[0049] Temperature sensor 12, humidity sensor 13, and gas sensor 14 are fixed on the inner wall of each proofing box 1. This application also provides a controller capable of automatic control. Temperature sensor 12, humidity sensor 13, and gas sensor 14 are connected to the controller via electrical connection. The controller is also connected to blower 21 and exhaust fan 31. When temperature sensor 12, humidity sensor 13, and gas sensor 14 detect that a certain data in proofing box 1 exceeds the set value, they can transmit a signal to the controller and control the corresponding blower 21 and exhaust fan 31 to start. This allows for automatic monitoring of the internal environment of proofing box 1 during the dough proofing process, which is more conducive to the proofing of the dough and avoids the need for manual monitoring.

[0050] Reference Figure 2 , Figure 3 and Figure 2The proofing box 1 is also equipped with a control device 5 for controlling the opening and closing of the air supply duct 22 and the exhaust duct 32. The device includes an air supply baffle 51 that is slidably inserted into the air supply duct 22 and an exhaust baffle 52 that is slidably inserted into the exhaust duct 32. By sliding the air supply baffle 51 and the exhaust baffle 52, the opening degree of the air supply duct 22 and the exhaust duct 32 can be controlled to control the air volume entering the proofing box 1 and the air volume being drawn out of the proofing box 1, so as to facilitate precise adjustment and thus keep the proofing box 1 in a better proofing condition. The control device 5 also includes a linkage component 53 installed on the proofing box 1. The linkage component 53 includes a linkage rod 531 slidably installed on the proofing box 1. The linkage rod 531 is installed along the length of the proofing box 1 and is located at the connection between two adjacent proofing boxes 1 and on the side close to the box door 11. A pair of L-shaped connecting rods 532 are symmetrically installed at both ends of the linkage rod 531. The ends of the connecting rods 532 away from the linkage rod 531 are fixed to the air supply baffle 51 or the exhaust baffle 52. When it is necessary to control the air volume delivered to the proofing box 1, the operator pulls the linkage rod 531, thereby synchronously controlling the movement of the air supply baffle 51 and the exhaust baffle 52, so that the air supply duct 22 and the exhaust duct 32 open to the appropriate size, and controlling the amount of air inlet and outlet.

[0051] Reference Figure 3 , Figure 4 and Figure 2 Figure 3 Figure 4Both connecting rods 532 are equipped with indicators 54 for workers to observe the opening degree of the air supply duct 22 and the exhaust duct 32. A pair of limiting rods 55 are provided on the linkage rod 531 to control the sliding of the linkage rod 531 and to limit its movement. The indicators 54 include indicator rods 541 that pass horizontally through the connecting rods 532. One end of the indicator rod 541 is fixed to the outer wall of the proofing box 1. The connecting rod 532 can slide along the indicator rod 541 and also serves as a guide. Multiple indicator marks 542 are evenly arranged on the indicator rod 541 along its length. 542 corresponds to different opening degrees of the air supply duct 22 or the exhaust duct 32 respectively; when the air supply baffle 51 and the exhaust baffle 52 are controlled to slide, the operator can observe the movement position of the connecting rod 532 on the indicator rod 541, thereby judging the opening degree of the air supply duct 22 and the exhaust duct 32; a return spring 56 is provided on the indicator rod 541 and located between the outer wall of the proofing box 1 and the connecting rod 532. The return spring 56 is sleeved on the indicator rod 541. When it is necessary to close the air supply duct 22 and the exhaust duct 32, the air supply baffle 51 and the exhaust baffle 52 are pulled back to their original positions under the action of the return spring 56. Two limiting rods 55 are positioned near the ends of the linkage rod 531. The limiting rods 55 pass horizontally through the linkage rod 531, and the linkage rod 531 and the limiting rods 55 are in sliding engagement. The limiting rods 55 are vertically fixed to the proofing box 1. The limiting rods 55 are threaded, and a limiting nut 551 is threadedly connected to the limiting rods 55. The limiting nut 551 is located between the linkage rod 531 and the opening of the proofing box 1, and the limiting nut 551 can abut against the linkage rod 531. When the linkage rod 531 is pulled to the designated position, the limiting nut 551 is rotated, and the limiting nut 551 abuts against the linkage rod 531, preventing the linkage rod 531 from sliding towards the opening of the proofing box 1 under the action of the return spring 56, thereby fixing the position of the linkage rod 531 on the limiting rods 55.

[0052] The implementation principle of the circulating air guiding structure in the proofing box of dough products in this application embodiment is as follows: When the dough in the proofing box 1 is proofing, air is introduced into the proofing box 1. The air flows into the proofing box 1 through the air supply pipe 22 and flows along the air guiding channel 42 inside the proofing box 1, thereby making the air in the proofing box 1 flow. The flowing air will drive the heat and gas inside to flow. Finally, under the action of the exhaust fan 31, the air containing heat and gas is discharged to the outside of the proofing box 1, thereby making the proofing environment inside the proofing box 1 more conducive to the proofing of the dough.

The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments.
