Description

Technical Field

[0001] This utility model relates to the field of proofing cabinet technology, specifically to a proofing cabinet based on double-layer airflow circulation. Background Technology

[0002] In the field of proofing cabinet technology, commercially available proofing cabinets typically include a cabinet body, a functional module for generating a suitable temperature and humidity environment, control components, and an openable cabinet door. Their core function is to provide suitable temperature and humidity conditions for dough and other ingredients to complete the proofing process. During use, the operator places a tray containing the dough onto the support structure inside the cabinet, sets the required proofing parameters through the control components, activates the functional module to generate a temperature and humidity airflow, and after the ingredients have proofed for a certain period inside the cabinet, opens the cabinet door and removes the tray.

[0003] However, existing proofing cabinets have many shortcomings in practical applications. Firstly, regarding temperature and humidity uniformity, existing equipment mostly relies on a single airflow delivery method, either supplying air from the bottom or the side only. This results in insufficient airflow circulation within the cabinet, easily leading to significant temperature and humidity differences between the upper and lower layers and the front and back sides. Consequently, the dough in different locations proofs unevenly; some dough may proof slowly due to insufficient temperature and humidity, while others may over-proof due to excessive temperature and humidity, severely affecting the stability of the proofed quality. Secondly, in terms of steam handling, existing proofing cabinets lack a dedicated steam collection structure. The steam generated during proofing condenses into water droplets on the top or inner walls of the cabinet. These droplets eventually drip directly into the tray below, causing localized dampness on the dough surface, leading to deformation, poor texture, and other problems, thus ruining the overall proofing effect. Furthermore, regarding the positioning and placement of trays, existing proofing cabinets rely on manual alignment by operators, lacking effective positioning structures. During the proofing process, airflow within the cabinet or slight shaking of the cabinet can cause trays to shift, affecting not only the normal circulation of airflow but also potentially causing trays to tilt, food to fall, and increasing operational risks and inconvenience. Utility Model Content

[0004] The problem this invention aims to solve is to provide a proofing cabinet based on a double-layer airflow circulation system, in order to address the issues of uneven temperature and humidity, water vapor dripping and affecting food quality, easy tray displacement, and inconvenient use of auxiliary structures in existing proofing cabinets.

[0005] The technical solution provided by this utility model to solve the above problems is as follows: a proofing cabinet based on double-layer airflow circulation, including a cabinet body, a temperature and humidity generating chamber, a cover plate, and a control component. The temperature and humidity generating chamber is located inside the cabinet body and is located on the inner wall of the cabinet body. The control component is installed on the top of the cabinet body. The cover plate is rotatably connected to the side of the cabinet body. It also includes an air supply component, a water vapor collection component, and a limiting component. The air supply component is used to deliver the airflow generated in the temperature and humidity generating chamber to various parts of the cabinet body, so that the temperature and humidity inside the cabinet body are kept balanced. The water vapor collection component is used to collect the generated water vapor to prevent water vapor from falling into the tray. The limiting component is used to limit the tray.

[0006] More preferably, the air supply assembly includes an air collection hood and a central air supply duct. The air collection hood is located at the bottom of the cabinet, and the airflow from the temperature and humidity generating chamber is discharged from the air collection hood. The central air supply duct is installed on the inner side wall of the cabinet and is connected to the temperature and humidity generating chamber, so that the airflow from the temperature and humidity generating chamber is discharged through the central air supply duct.

[0007] More preferably, the air collection hood is provided with exhaust holes evenly spaced.

[0008] More preferably, the central air supply duct and the air collection hood work together to allow the airflow in the temperature and humidity generation chamber to circulate inside the cabinet, thereby making the temperature and humidity inside the cabinet more uniform.

[0009] More preferably, the water vapor collection assembly includes support rods, a beveled frame, and a collection frame. Several support rods are evenly installed on the inner wall of the cabinet and are used to support the tray. The beveled frame is installed on the top of the cabinet and the collection frame is snapped into the inside of the beveled frame.

[0010] More preferably, the inclined frame is a frustum shape.

[0011] More preferably, three support rods are arranged in a row.

[0012] More preferably, the limiting component includes a fixed frame, a telescopic plate, and a spring. Several fixed frames are fixedly connected to the cover plate, and each cover plate is slidably connected to a telescopic plate. Each telescopic plate is connected to a fixed frame by a symmetrically arranged spring.

[0013] Compared with the prior art, the advantages of this utility model are: This utility model can realize double-layer airflow circulation inside the cabinet through the air supply component. The air collection hood evenly discharges airflow from the bottom of the cabinet, and the central air supply pipe delivers airflow from the side wall of the cabinet. The two work together to allow the temperature and humidity airflow generated by the temperature and humidity generation chamber to flow fully inside the cabinet, effectively eliminating the temperature and humidity differences in different areas inside the cabinet, ensuring that the dough in all positions inside the cabinet is in a consistent proofing environment, and improving the uniformity of the dough proofing quality.

[0014] It is equipped with a special water vapor collection component. The truncated square frame can guide the rising water vapor to condense on its inner wall. The condensed water droplets can flow down the slope into the collection frame that is stuck in the frame, preventing water vapor from dripping directly onto the surface of the dough in the tray. This prevents the dough from deforming or becoming tasteless due to moisture, and ensures the appearance and quality of the dough after proofing.

[0015] The equipped limiting components function during the closing of the cover. The cover moves the fixed frame and the telescopic plate. After the telescopic plate contacts the tray, it exerts a clamping force on the tray under the action of the spring. This can both push the tray to adjust its position so that multiple trays are neatly arranged in the cabinet, and also stabilize and limit the tray to prevent it from shifting when the airflow circulates or the cabinet shakes slightly, thus ensuring the stability of the proofing process.

[0016] The overall structural design takes into account practicality and convenience. The collection frame is installed in the sloping frame by snapping. When cleaning up the collected water, the collection frame can be directly removed, making the operation simple and convenient. The support rods are set in groups of three, which facilitates quick and stable placement of the tray, reduces operational errors, and improves the convenience of use. Attached Figure Description

[0027] Example: As shown in the attached figure, a proofing cabinet based on double-layer airflow circulation includes a cabinet body 1, a temperature and humidity generating chamber 2, a cover plate 6, and a control component 5. The temperature and humidity generating chamber 2 is located inside the cabinet body 1 and is situated on the inner wall of the cabinet body 1. The control component 5 is installed on the top of the cabinet body 1. The cover plate 6 is rotatably connected to the side of the cabinet body 1. The cabinet also includes an air supply component, a water vapor collection component, and a limiting component. The air supply component is used to deliver the airflow generated in the temperature and humidity generating chamber 2 to various parts inside the cabinet body 1, so that the temperature and humidity inside the cabinet body 1 are kept balanced. The water vapor collection component is used to collect the generated water vapor to prevent water vapor from falling into the tray. The limiting component is used to limit the position of the tray.

[0028] In this embodiment, the air supply assembly specifically includes an air collecting hood 3 and a central air supply pipe 4. The air collecting hood 3 is located at the bottom of the cabinet 1, and exhaust holes are evenly distributed on the air collecting hood 3. The airflow from the temperature and humidity generating chamber 2 is discharged from the air collecting hood 3. The central air supply pipe 4 is installed on the inner side wall of the cabinet 1 and is connected to the temperature and humidity generating chamber 2, so that the airflow from the temperature and humidity generating chamber 2 is discharged through the central air supply pipe 4. The central air supply pipe 4 and the air collecting hood 3 work together to allow the airflow from the temperature and humidity generating chamber 2 to circulate inside the cabinet 1, thereby making the temperature and humidity inside the cabinet 1 more uniform. Furthermore, the water vapor collection assembly includes support rods 7, inclined frames 8, and collection frames 9. Several support rods 7 are evenly installed on the inner wall of the cabinet 1, with three support rods 7 forming a row. A tray can be placed on the top of each row of support rods 7. The inclined frames 8 are installed on the top of the cabinet 1. The inclined frames 8 are truncated pyramidal in shape. The collection frames 9 are snapped into the inside of the inclined frames 8. The collection frames 9 have a double-layered U-shaped structure. Water vapor adheres to the inner wall of the inclined frames 8 and flows into the collection frames 9 for collection under the guiding effect of the inclined frames 8, which can prevent water vapor from dripping into the tray. Furthermore, the limiting component includes a fixed frame 10, a telescopic plate 11, and a spring 12. Several fixed frames 10 are fixedly connected to the cover plate 6. Each cover plate 6 is slidably connected to a telescopic plate 11. Each telescopic plate 11 is connected to a fixed frame 10 by a symmetrically arranged spring 12. When the cover plate 6 rotates to close, it drives the fixed frame 10 and the telescopic plate 11 to rotate. The telescopic plate 11 contacts the pallet, thereby pushing the pallet to move, so that the pallet is placed neatly and can limit the pallet. When the telescopic plate 11 is squeezed, the spring 12 is stretched.

[0029] First, open the cover 6 and place the trays containing dough on the support rods 7 on the inner wall of the cabinet 1, with three support rods 7 per row, ensuring the trays are placed stably and with adequate airflow clearance. Then, rotate the cover 6 to close the cabinet 1. The cover 6 moves the fixed frame 10 and the telescopic plate 11 slidably connected to it synchronously. After the telescopic plate 11 contacts the tray, it is blocked by the tray and slides into the fixed frame 10. At this time, the symmetrically arranged springs 12 are stretched and generate a reverse elastic force. Under the action of the elastic force, the telescopic plate 11 presses tightly against the side of the tray, which can both push the tray to adjust its position so that multiple trays are neatly arranged in the cabinet 1, and stabilize and limit the trays to prevent them from shifting or shaking during airflow circulation. Then, according to the dough proofing requirements, set the appropriate temperature and humidity parameters through the control component 5 at the top of the cabinet 1, and start the temperature and humidity generating chamber 2 to generate temperature and humidity airflow. Part of the airflow generated by the temperature and humidity generating chamber 2 is discharged upward through the exhaust hole on the air collection hood 3 at the bottom of the cabinet 1, and the other part is discharged upward through the exhaust hole on the air collection hood 3 at the bottom of the cabinet 1. Part of the airflow is delivered to the center and surrounding areas of cabinet 1 through the central air supply pipe 4 on the inner side wall of cabinet 1. The combination of these two methods creates a circulating airflow inside cabinet 1, allowing the temperature and humidity in each area of ​​cabinet 1 to quickly become uniform. This gradually brings the temperature and humidity in each area of ​​cabinet 1 to the set standard, avoiding uneven dough proofing due to local temperature and humidity differences, and ensuring uniform and stable dough quality after proofing. During the proofing process, the rising water vapor condenses upon contact with the inclined frame 8 at the top of cabinet 1. The inclined inner wall guides the rising water vapor to flow along the inclined surface after condensation, eventually falling into the collection frame 9 that is snapped inside the inclined frame 8 for collection. This effectively prevents water vapor from dripping directly onto the dough in the tray, preventing the dough surface from becoming damp and deformed or affecting the fermentation effect. At the same time, the collection frame 9 uses a snap-fit ​​method for easy disassembly and cleaning later. After proofing is completed, the cover plate 6 is rotated in the opposite direction to open cabinet 1. At this time, the telescopic plate 11 returns to its initial position under the reset action of the spring 12, releasing the restriction on the tray. Finally, the tray can be removed from the support rod 7. If you need to clean up the collected water vapor, you can directly remove the collection box 9 that is clipped inside the inclined frame 8, pour out the water inside, and then clip it back into place.

[0030] The above description only illustrates the preferred embodiment of this utility model and should not be construed as limiting the scope of the claims. This utility model is not limited to the above embodiments, and variations in its specific structure are permitted. All changes made within the scope of the independent claims of this utility model are also within the scope of protection of this utility model.
