Description

Technical Field

[0001] This invention relates to the field of baking oven technology, and more particularly to a rotary baking oven for cake processing. Background Technology

[0002] A rotary oven for cake baking is a large piece of equipment commonly used in commercial baking; it is also often called a hot air rotary oven or rotary oven. It solves the problem of uneven heating in traditional ovens by continuously rotating the food during baking and combining it with powerful hot air circulation.

[0003] Currently, existing rotary ovens for cake processing mainly rely on fixed air ducts inside the oven body in conjunction with a main fan to complete hot air circulation and heat exchange. The inner side walls and door panels of the oven are usually equipped with fixed perforated mesh panels and fixed-angle guide vanes. Hot air is blown out unidirectionally through the through-holes in the mesh panels, forming a fixed airflow field inside the oven. When the equipment is working, the rotating platform only undertakes the function of carrying and rotating the cake. The air guiding and turbulence structures inside the oven and the rotating trolley operate independently of each other, without any mechanical linkage. The blades inside the oven are mostly fixedly installed or rely on independent electrical control mechanisms to oscillate. The overall structure is simple, and the hot air delivery angle and turbulence range are in a fixed state. It is impossible to dynamically adjust the turbulence state in real time according to the rotation of the oven chamber. This is the conventional and common structure of current rotary ovens for baking.

[0004] However, the fixed hot air circulation method of existing traditional rotary baking ovens easily creates hot air dead zones and localized heat accumulation areas inside the oven chamber, resulting in uneven heat distribution within the oven. Traditional equipment lacks a rotating linkage turbulence structure, making it impossible to dynamically disrupt the hot air flow inside the oven. This leads to significant differences in heating of cakes from top to bottom and left to right, easily causing uneven browning and inconsistent ripeness, greatly increasing the defect rate of cake baking. It cannot meet the needs of high-precision and consistent large-scale cake production. At the same time, the frequent opening and closing of the oven door will cause stable low-temperature blind spots to form in the corresponding area of ​​the oven door. Conventional equipment cannot specifically compensate for the low-temperature areas with hot air, resulting in a large overall temperature difference in the oven chamber. Summary of the Invention

[0005] The purpose of this invention is to provide a rotary baking oven for cake processing, which solves the problem of uneven heat distribution inside the oven in existing rotary baking ovens for cake processing.

[0006] To achieve the above objectives, the present invention provides a rotary baking oven for cake processing, comprising an oven body, a door panel hinged to the open end of the oven body, a rotating support platform fixedly installed on the inner wall of the bottom of the oven body, perforated mesh panels fixedly connected to the inner side wall of the oven body and the end face of the door panel facing the oven body, a pump connected to the perforated mesh panels on the side wall of the oven body, a linkage collar fixedly connected to the outer periphery of the rotating support platform, and a dynamic turbulence component correspondingly installed on the outer side of each perforated mesh panel; The dynamic turbulence component includes a pair of mounting horizontal plates. Each set of mounting horizontal plates is fitted with an elastic rotating shaft between its upper and lower inner walls. Vertical guide vanes are rotatably mounted between the two sets of vertically aligned elastic rotating shafts. Multiple positioning mounting protrusions are fixedly connected to the surface of the perforated mesh plate facing the dynamic turbulence component. All the positioning mounting protrusions are arranged in a rectangular array. Assembly holes are symmetrically opened on the left and right sides of the mounting horizontal plate. The positioning mounting protrusions pass through the corresponding assembly holes and are locked and fixed by threaded locking rings. A linkage disturbance rod group that can cooperate with the dynamic turbulence component for transmission is fixedly connected to the upper end of the linkage collar. The linkage disturbance rod group includes a pair of vertical linkage uprights. Multiple horizontal blade scrapers are fixed to the side wall of each vertical linkage upright.

[0007] All of the horizontal blade scrapers are arranged vertically at equal intervals along the height direction of the vertical linkage upright. The horizontal blade scrapers can abut against each vertical guide vane to make the blades swing, which is used to effectively disrupt the hot air flow with a fixed direction inside the furnace.

[0008] The upper end of the linkage collar is symmetrically fixed with two cylindrical seats, and the lower end of the vertical linkage rod is movably inserted into the cylindrical seat. Multiple sets of positioning insertion holes are opened on the side wall of the vertical linkage rod and the cylindrical seat. Locking pins are inserted into the mutually aligned positioning insertion holes and locked by threads to limit the assembly angle of the vertical linkage rod.

[0009] Among them, the outward extension length of all the vertical guide vanes is different, and the arrangement density of the vertical guide vanes on the outside of the perforated mesh plate on the side of the door panel is greater than the arrangement density of the vertical guide vanes on the outside of the perforated mesh plate on the side wall of the furnace body, which is used to specifically compensate for the low temperature area formed by heat dissipation due to opening and closing at the door panel position.

[0010] The furnace body opening has a fixed trolley transition ramp installed at the bottom. The trolley transition ramp is located below the door panel and extends downwards to the ground level outside the furnace body. The trolley transition ramp has multiple anti-slip ribs integrally formed on its surface to prevent the trolley carrying the cake from sliding or shifting during the pushing and pulling process.

[0011] The door panel has a fixed sealing strip on its side panel. The sealing strip is made of high-temperature resistant food-grade silicone rubber. After the door panel is closed, the sealing strip is elastically pressed and adhered to the inner wall of the furnace opening.

[0012] A temperature controller is fixedly mounted on the side wall of the furnace body, and the signal terminal of the temperature controller is electrically connected to the pump.

[0013] The elastic rotating shaft has a built-in torsion spring component. The two ends of the torsion spring are respectively snapped and fixed to the inner wall of the mounting plate and the end of the vertical guide vane. When the horizontal blade scraper disengages from the contact with the vertical guide vane as the rotating support platform revolves, the torsion spring can drive the vertical guide vane to automatically rotate and reset, thereby realizing the continuous reciprocating oscillation of the vertical guide vane to turbulence.

[0014] The transverse blade scraper is provided with an inclined guide surface at the end away from the vertical linkage rod, and the inclined guide surface contacts and cooperates with the surface of the vertical guide blade to reduce the rigid impact during the process of moving the vertical guide blade.

[0015] The perforated mesh plate is covered with evenly arranged guide holes, and the high-temperature hot air output by the pump can pass through the guide holes and be delivered to one side of the vertical guide vanes.

[0016] This invention discloses a rotary baking oven for cake processing. Through a rotating support platform, a linkage collar drives a linkage disturbance rod group and a dynamic disturbance component to form a purely mechanical linkage disturbance structure. The revolving horizontal blade scraper can periodically press and drive the vertical guide vanes to swing. Combined with the internal torsion spring of the elastic rotating shaft, the blades can continuously swing back and forth, which can continuously disrupt the hot air flow with a fixed direction in the oven. This effectively eliminates the dead corners of hot air flow that exist in traditional rotary ovens. With the dense arrangement and differentiated extension structure of the vertical guide vanes on the door side, it can specifically compensate for the low temperature area caused by the opening and closing of the oven door, effectively balance the overall temperature difference in the oven chamber, and greatly improve the uniformity and consistency of heating for the entire batch of cake baking. This equipment achieves multiple baking mode switching through the adjustable plug-in structure of the vertical linkage rod and the cylinder base, effectively improving the equipment's adaptability. By using the positioning plug-in hole and locking pin to lock the positioning vertical linkage rod, the linkage disturbance rod group can be linked with the dynamic disturbance component, causing the vertical guide vanes to swing at high frequency, meeting the strong disturbance baking requirements of thick cakes and heavy oil cakes. Adjusting the angle of the vertical linkage rod can disengage the mechanical actuation structure, allowing the vertical guide vanes to swing passively by hot air, which is suitable for the gentle baking conditions of soft cakes such as chiffon and sponge. The dynamic disturbance component can also be removed to use a fixed air duct for air supply, adapting to a variety of special baking processes and broadening the equipment's application range. This equipment effectively improves baking precision and equipment stability by combining temperature control linkage, sealing protection, and anti-slip docking structure. The temperature controller monitors the internal temperature of the oven in real time and controls the hot air output of the pump in linkage to stabilize the oven heat field and avoid defects such as cake cracking and shrinkage. The sealing strip on the inside of the door panel fits against the inner wall of the oven to seal the gaps in the oven opening, reduce the loss of hot air and the intrusion of cold air, reduce energy consumption and maintain a constant temperature baking environment. The trolley transition ramp at the bottom of the oven can smoothly dock the trolley, and its anti-slip structure prevents the trolley from sliding and bumping into the internal components of the oven, reducing equipment wear and tear and ensuring long-term stable operation of the equipment.

[0027] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0028] Example: Please refer to Figures 1 to 8This invention provides a rotary baking oven for cake processing, comprising an oven body 1, with a door panel 2 hinged to the open end of the oven body 1; a rotating support platform 3 is fixedly installed on the inner wall of the bottom of the oven body 1; perforated mesh panels 4 are fixedly connected to the inner side wall of the oven body 1 and the end face of the door panel 2 facing the oven body 1; a pump is externally connected to the perforated mesh panels 4 on the side wall of the oven body 1; a linkage collar 5 is fixedly connected to the outer periphery of the rotating support platform 3; and dynamic turbulence components 6 are correspondingly installed on the outer side of each perforated mesh panel 4. The dynamic turbulence components 6 include paired installation... The horizontal plate 600 is equipped with elastic rotating shafts 601 between the upper and lower inner walls of a single set of mounting horizontal plates 600. Vertical guide vanes 602 are mounted between two sets of vertically aligned elastic rotating shafts 601. Multiple positioning mounting protrusions 603 are fixedly connected to the surface of the hollow mesh plate 4 facing the dynamic turbulence component 6. All positioning mounting protrusions 603 are arranged in a rectangular array. Assembly holes are symmetrically opened on the left and right sides of the mounting horizontal plate 600. The positioning mounting protrusions 603 pass through the corresponding assembly holes and are locked and fixed by threaded locking rings 604.

[0029] In this structure, the rotating support platform 3 is linked with the linkage disturbance rod group 7 and the dynamic disturbance components 6 on both sides of the oven body 1 and the door panel 2 to form a purely mechanical linkage. Therefore, there is no need to add an independent swing drive mechanism to realize the automatic disturbance of the vertical guide vane 602. At the same time, relying on the air guide base of the hollow mesh plate 4 and the swing action of the vertical guide vane 602, the hot air flow with the fixed direction inside the oven body 1 can be effectively disrupted, thereby significantly eliminating the hot air dead corner inside the oven body 1 and improving the heating uniformity of the cake baking process.

[0030] Please refer to Figures 2 to 8 The upper end of the linkage collar 5 is fixedly connected to a linkage disturbance rod group 7 that can cooperate with the dynamic disturbance component 6 for transmission. The linkage disturbance rod group 7 includes paired vertical linkage rods 700. Multiple horizontal blade scrapers 701 are fixed to the side wall of each vertical linkage rod 700. All horizontal blade scrapers 701 are arranged vertically at equal intervals along the height direction of the vertical linkage rods 700. The horizontal blade scrapers 701 can abut against each vertical guide vane 602 to make the vane swing, which is used to effectively disrupt the hot air flow with a fixed direction inside the furnace body 1. The upper ends of the linkage collar 5 are symmetrically fixed with cylinder seats 702, and the vertical linkage rods 700 are fixed to the cylinder seats 702. The lower end is movably inserted into the cylinder base 702. Multiple sets of positioning insertion holes 703 are opened on the side wall of the vertical linkage rod 700 and the cylinder base 702. Locking pins 704 are inserted into the aligned positioning insertion holes 703 and locked by threads to limit the assembly angle of the vertical linkage rod 700. All the vertical guide vanes 602 extend outwards by different lengths. The vertical guide vanes 602 located outside the perforated mesh plate 4 on the side of the door panel 2 have a higher arrangement density than the vertical guide vanes 602 located outside the perforated mesh plate 4 on the side wall of the furnace body 1. This is used to specifically compensate for the low temperature area formed by heat dissipation due to opening and closing at the door panel 2.

[0031] The vertical linkage rod 700 and the cylinder base 702 adopt an adjustable assembly structure with a plug-in fit, which allows for flexible adjustment of the assembly angle and position of the vertical linkage rod 700. This enables the equipment to have three operating modes suitable for baking conditions. For cake baking scenarios that require high air volume and strong turbulence, the position of the vertical linkage rod 700 can be locked, so that the linkage disturbance rod group 7 and the dynamic turbulence component 6 are precisely aligned and matched. The vertical guide vane 602 is oscillating at high frequency by mechanical movement, which enhances the hot air disturbance effect. For gentle baking conditions, the locking limit of the vertical linkage rod 700 and the cylinder base 702 can be released and rotated to adjust the position, allowing the horizontal blades to scrape... During its revolution, the 701 strip disengages from the vertical guide vane 602 and relies solely on the wind power output by the pump to passively swing the vertical guide vane 602, achieving gentle airflow turbulence. For special baking needs, the dynamic turbulence component 6 can be directly disassembled to adapt to baking conditions with pure fixed air duct air supply. At the same time, the locking and limiting structure of multiple positioning insertion holes 703 and locking pins 704 can ensure that the vertical linkage rod 700 will not shift or shake during the high-speed operation of the equipment after adjustment and positioning, effectively ensuring the operational stability of the mechanical linkage structure above the linkage collar 5 and significantly reducing the probability of abnormal noise during equipment operation and wear of parts transmission.

[0032] Please refer to Figures 2 to 8 A trolley transition ramp 8 is fixedly installed at the bottom of the opening of the furnace body 1. The trolley transition ramp 8 is located below the door panel 2, and its lower end extends downward to the ground level outside the furnace body 1. The trolley transition ramp 8 has multiple anti-slip ribs integrally formed on its surface to prevent the trolley carrying the cake from sliding or shifting during the pushing and pulling process. A sealing strip 9 is fixed to the side panel of the door panel 2. The sealing strip 9 is made of high-temperature resistant food-grade silicone rubber. After the door panel 2 is closed, the sealing strip 9 is elastically pressed and adhered to the inner wall of the opening of the furnace body 1. A temperature controller 10 is fixedly installed on the side wall of the furnace body 1. The signal terminal of the temperature controller 10 is electrically connected to the pump. A torsion spring component is built into the elastic rotating shaft 601. The two ends of the torsion spring are respectively snapped and fixed to the mounting... The inner wall of the horizontal plate 600 and the end of the vertical guide vane 602 are connected. When the horizontal blade scraper 701 revolves with the rotating support platform 3 and disengages from the contact with the vertical guide vane 602, the torsion spring can drive the vertical guide vane 602 to automatically rotate and reset, thereby realizing the continuous reciprocating oscillation and turbulence of the vertical guide vane 602. The end of the horizontal blade scraper 701 away from the vertical linkage rod 700 is provided with an inclined guide surface, and the inclined guide surface contacts and cooperates with the plate surface of the vertical guide vane 602 to reduce the rigid impact during the process of moving the vertical guide vane 602. The perforated mesh plate 4 is covered with evenly arranged guide holes, and the high-temperature hot air output by the pump can pass through the guide holes and be delivered to one side of the vertical guide vane 602.

[0033] The temperature controller 10 is fixedly mounted on the side wall of the oven body 1 to stably collect the baking temperature inside the oven chamber, avoiding the deviation of temperature measurement data caused by external installation. At the same time, the temperature controller 10 is electrically linked with the pump, which can dynamically adjust the hot air delivery parameters according to the real-time temperature inside the oven body 1. In addition, it works with the dynamic turbulence component 6 inside the oven body 1 to optimize the hot air distribution, continuously maintain the constant temperature of the oven chamber, and ensure the stable quality of cake baking.

[0034] Working principle: During equipment operation, the heating circulation pump installed on the side wall of furnace body 1 continuously outputs high-temperature hot air. The high-temperature hot air can penetrate the evenly distributed guide holes on the surface of the perforated mesh plate 4 and be delivered to the area where the vertical guide vanes 602 are installed. The perforated mesh plate 4 is fixed to the inner side wall of furnace body 1 and the end face of door panel 2 facing furnace body 1, which can evenly distribute the delivered hot air and avoid the problem of local high temperature accumulation caused by concentrated hot air jet. The rotating support platform 3 installed on the inner wall of the bottom of furnace body 1 continuously revolves at a uniform speed. During the rotation of the support platform 3, the linkage collar 5 of the outer fixed set can be driven to rotate synchronously. During the rotation of the linkage collar 5, the linkage disturbance rod group 7 fixed at the upper end can be driven to revolve around the center of the furnace. During the revolve of the linkage disturbance rod group 7, the horizontal blade scrapers 701 arranged at equal intervals on the side wall of the vertical linkage rod 700 can periodically contact and press against the vertical guide vane 602. The inclined guide surface set at the end of the horizontal blade scraper 701 can flexibly contact the vertical guide vane 602, reducing the mechanical impact and abnormal noise of the equipment caused by rigid contact. After being subjected to the pressing force, the vertical guide vane 602 can deflect and swing by relying on the elastic rotating shaft 601 assembled at both ends. During the deflection of the vertical guide vane 602, the hot air discharged by the hollow mesh plate 4 can be continuously disturbed, disrupting the hot air flow with a fixed direction inside the furnace body 1, eliminating the dead angle of hot air flow inside the furnace. The vertical guide vane 602 at the corresponding position of the door plate 2 has a larger arrangement density and the blade extension length is set differently, which can continuously compensate for the low temperature area generated by the opening and closing of the door plate 2. The overall temperature difference in the furnace is balanced. After the horizontal blade scraper 701 is separated from the surface of the vertical guide vane 602 as the rotating support platform 3 revolves, the torsion spring inside the elastic shaft 601 can release elastic potential energy. The two ends of the torsion spring are respectively supported by the inner wall of the mounting plate 600 and the end of the vertical guide vane 602 to form a fixed support structure, which can drive the vertical guide vane 602 to quickly rotate and reset. The vertical guide vane 602 continuously completes the swing and reset action as it revolves, realizing the uninterrupted dynamic turbulence operation of hot air inside the furnace body 1. The equipment can switch modes according to different cake baking conditions. The cylinder seat 702 fixed on both sides of the upper end of the linkage collar 5 forms a plug-in structure with the vertical linkage rod 700. Align the positioning plug-in holes 703 at different positions on the side wall of the vertical linkage rod 700 and the cylinder seat 702 and thread the locking pin 704 through to lock it. This can fix the assembly angle and height of the vertical linkage rod 700 to meet the baking requirements of large air volume and strong turbulence. Release the locking pin 704 and rotate to adjust the angle of the vertical linkage rod 700. This can make the horizontal blade scraper 701 separate from the movement trajectory of the vertical guide vane 602. The vertical guide vane 602 only relies on the hot air force delivered by the pump to swing passively to achieve gentle baking operation. After completely disassembling the dynamic turbulence component 6, it can be adapted to special baking conditions with fixed air duct air supply. Throughout the baking process, the temperature controller 10 mounted on the side wall of the oven body 1 continuously collects real-time temperature data inside the oven chamber. The temperature controller 10 adjusts the hot air delivery parameters of the heating circulation pump in real time through electrical connection. Combined with the dynamic turbulence effect of the dynamic turbulence component 6, it stabilizes the thermal environment of the oven chamber. When the door panel 2 is closed, the high-temperature resistant food-grade silicone rubber sealing strip 9 fixed on the inner side of the door panel tightly presses against the inner wall of the opening of the oven body 1, sealing the gaps in the opening of the oven body 1, reducing hot air leakage and the intrusion of cold air from the outside, and maintaining a constant temperature baking environment in the oven chamber. The trolley transition ramp 8 fixed at the bottom of the opening of the oven body 1 connects to the internal track and the ground. The anti-slip ribs integrally formed on the ramp surface can prevent the cake trolley from slipping or shifting during the pushing and pulling process, avoid the trolley from bumping into the internal components of the oven, and ensure the continuous and stable operation of the equipment.
