Description

Technical Field

[0001] This invention relates to the field of food processing equipment technology, and in particular to a pancake machine. Background Technology

[0002] Pancakes are a traditional food. In northern China, they are a breakfast food, usually eaten with ingredients such as fermented bean curd and chives. In the south, they are often eaten after meals, as desserts, or as a late-night snack.

[0003] Traditionally, pancakes are mostly made manually. Batter is poured onto a griddle-like plate, also called a griddle, which has a heat source at the bottom. The batter is spread thinly on the griddle using a pancake rake. After a while, the batter heats up and forms a pancake, completing one pancake. Finally, the pancake is scooped into a basket. With the development of the pancake industry, customers have higher expectations for the taste of pancakes, and more and more customers prefer freshly made, hot pancakes.

[0004] Currently, the traditional method of making pancakes by hand is inefficient, especially during peak meal times when there are many customers. It is difficult to meet the demand for freshly made pancakes, which may lead to the loss of some customers. When more griddles are added to increase the number of pancakes made, one staff member is needed to manage the production of multiple pancakes at the same time. This can easily lead to inconsistent pancake production times, affecting quality. Alternatively, having multiple staff members to manage the production can also increase production costs. Summary of the Invention

[0005] This invention provides a pancake machine. This device can achieve uninterrupted coordinated operation and continuously produce pancakes, reducing manual labor and labor costs while realizing fully automated production, greatly improving production efficiency, and ensuring that pancakes can be efficiently produced at any time to meet customer needs.

[0006] This invention provides a pancake maker, including a worktable, griddles, and a pancake rake for spreading batter. The bottom of the griddle is equipped with multiple heating modules for heating the griddle, with the number of heating modules corresponding to the number of griddles. The maker also includes a placement tray, a horizontal plate, a drive module, a dough feeding module, and a pancake scraping module. The placement tray is located on the upper part of the worktable and is rotatably connected to it. Multiple heating modules are evenly arranged along the perimeter of the upper surface of the placement tray. Multiple griddles are connected one-to-one to the upper part of each heating module. The pancake rake is positioned above one of the griddles. The horizontal plate is connected to the worktable via a lifting assembly. The vertical handle of the pancake rake extends through... A horizontal plate is rotatably connected to the pan, and a vertical handle is connected to a first motor. A drive module is connected to the placement plate to control the intermittent rotation of the placement plate, so that the pancake rake is positioned above the corresponding griddle with each rotation. A dough feeding module is connected to the operating table, and the discharge port of the dough feeding module is aligned with the middle of the griddle below the pancake rake. The dough feeding module is used to intermittently feed the batter to each griddle. A pancake shoveling module is fixedly connected to the operating table and is located above the adjacent griddle of the griddle corresponding to the pancake rake. The pancake shoveling module is used to shovel the spread pancake off the griddle. When the placement plate rotates, the griddle from which the pancake is shoveled rotates to the position corresponding to the pancake rake.

[0007] Preferably, there is a distance between the placement tray and the operating table, a sleeve is fixedly connected to the lower middle part of the placement tray, the lower end of the sleeve is rotatably connected to the operating table, the drive module includes a drive motor, the output end of the drive motor is fixedly connected to a first gear, a second gear is fixedly fitted on the sleeve, and the first gear and the second gear mesh.

[0008] Preferably, the dough feeding module includes: a dough cylinder, a partition, a feeding pipe, a placement plate, and a fixing column. The dough cylinder has an opening at the top. The partition is fixedly connected to the middle of the dough cylinder. The partition is conical in shape, and the bottom of the cone is connected to a feeding control valve. The inlet end of the feeding pipe is connected to the outlet end of the feeding control valve. The feeding pipe extends horizontally through the bottom of the dough cylinder and towards the pancake rake. The outlet of the feeding pipe faces downward and is located above the pancake rake scraper. The placement plate is fixedly connected to the lower end of the dough cylinder. A through hole is vertically opened in the middle of the placement plate. The fixing column is fixedly connected to the bottom of the placement plate and passes through the through hole and the middle of the sleeve. The lower end of the fixing column is fixedly connected to the operating table.

[0009] Preferably, the lifting assembly includes a base plate, which is fixedly connected to the operating platform. Multiple electric telescopic rods are provided between the base and the horizontal plate. The fixed end of the electric telescopic rod is fixedly connected to the horizontal plate, and the telescopic end of the electric telescopic rod is fixedly connected to the base plate.

[0010] Preferably, it also includes a horizontal plate, the other end of which is located between the griddle and the pancake rake. The horizontal plate has a vertically formed baffle hole along the outer diameter of the griddle, which is larger than the scraper length of the pancake rake. The baffle hole is used to block the spread batter and prevent the batter from falling off the edge of the griddle. A height adjustment component is provided on one side of the horizontal plate.

[0011] Preferably, the adjusting assembly includes a screw that penetrates the horizontal plate vertically and is threadedly connected to it. One end of the screw is connected to a second motor, and the mounting base of the second motor is fixedly connected to the lower end face of the horizontal plate. The other end of the screw is rotatably connected to the base plate. The outer cylinder of the fixed end of the electric telescopic rod penetrates the horizontal plate and is slidably connected to the horizontal plate.

[0012] Preferably, the pancake shovel module includes a connecting frame, which is fixedly connected to the upper end of the worktable. A horizontal slide rail is fixedly connected to one side of the connecting frame, and a sliding plate is slidably connected inside the slide rail. A lead screw is horizontally inserted into the sliding plate and the two are threaded together. Both ends of the lead screw are slidably connected to the slide rail. One end of the lead screw is connected to a third motor. A pancake shovel is connected to one side of the sliding plate. The blade of the pancake shovel is flush with the upper surface of the griddle. The initial position of the pancake shovel is close to the side of the pancake rake. When the sliding plate slides horizontally, the pancake shovel can scoop the spread pancake out of the placement plate and return to the initial position to scoop the next pancake from the griddle.

[0013] Preferably, the oiling module is fixedly connected to the slide plate via a fixing frame. The oiling module includes an oil hopper, and an oil supply control valve is connected to the bottom of the oil hopper. An oil supply pipe is connected to the outlet of the oil supply control valve, and a brush is connected to the outlet of the oil supply pipe. The brush is located between the pancake spatula and the pancake rake. When the pancake spatula removes the pancake, the brush with oil will move synchronously to brush oil onto the pancake. When the pancake spatula returns to its initial position, the brush brushes oil onto the pancake again. The oiled pancake is then placed on a rotating plate and rotated to the position of the pancake rake to feed and flatten the pancake.

[0014] Preferably, the worktable is located below the pancake shovel and equipped with a belt conveyor for catching and transporting the pancakes.

[0015] Preferably, the drive motor is a stepper motor.

[0016] Compared with the prior art, the beneficial effects of the present invention are: it can achieve uninterrupted coordination and continuous pancake production, reducing manual labor and labor costs, while also achieving fully automated production, greatly improving production efficiency, thus ensuring that pancakes can be efficiently produced at any time to meet customer needs.

[0017] In specific use, first adjust the pancake spatula in the pancake module to the correct height, ensuring it is flush with the top surface of the griddle. Then, fill the batter container with batter and the oil container with oil. After filling, press the start switch to start the automatic pancake machine. Once powered on, control the heating module to reach the optimal temperature, then control the second motor to drive the screw to rotate, thus raising the level plate to ensure it completely fits the griddle. The baffle holes ensure that the batter does not overflow from the griddle. Simultaneously, adjust the batter output to ensure... Ensure each portion of batter is evenly distributed onto the griddle. Then, control the electric telescopic rod to lower the pancake rake. During this descent, activate the first motor to rotate the rake. As the rake lowers, it spreads the batter evenly across the griddle. Once the pancake is flat and set, control the second motor to rotate in the opposite direction, raising the horizontal plate vertically. Simultaneously, extend the output end of the electric telescopic rod to slightly raise the rake, positioning it below the outlet of the feed pipe. Figure 1 As shown, at this time, the drive motor uses the meshing of the first and second gears to drive the sleeve and the placement plate to rotate 60° counterclockwise to enter the next process. At the same time, before the batter is fed onto the first griddle, the pancake shovel module and the oil brushing module also correspond to an empty griddle. At this time, the oil supply control valve and the third motor of the pancake shovel module are opened, and the oil enters the oil brush through the oil supply pipe. With the reciprocating motion of the slide plate on the slide rail, the empty griddle is evenly brushed with oil. Then, the placement plate is controlled to rotate 60° counterclockwise to start brushing. After the oil is applied, the griddle surface is smoothed. As the first griddle with a pancake rotates once, it reaches the pancake shovel of the pancake shovel module. At this point, the pancake on the griddle is ready, and the pancake shovel will be located on the side closer to the griddle. Then, controlled by a screw and a third motor, the pancake is shoveled off the griddle from left to right. The griddle falls onto the belt conveyor and is collected. While the pancake shovel is shoveling from left to right, a brush will also brush a layer of oil onto the upper surface of the griddle. When the pancake shovel returns to its initial position close to the griddle, the pancake removal step is completed. Attached Figure Description

[0030] Pancakes are a traditional food. In northern China, they are a breakfast food, usually eaten with ingredients such as fermented bean curd and chives. In the south, they are often eaten after meals, as desserts, or as a late-night snack.

[0031] Traditionally, pancakes are mostly made manually. Batter is poured onto a griddle-like plate, also called a griddle, which has a heat source at the bottom. The batter is spread thinly on the griddle using a pancake rake. After a while, the batter heats up and forms a pancake, completing one pancake. Finally, the pancake is scooped into a basket. With the development of the pancake industry, customers have higher expectations for the taste of pancakes, and more and more customers prefer freshly made, hot pancakes.

[0032] Currently, the traditional method of making pancakes by hand is inefficient, especially during peak meal times when there are many customers. It is difficult to meet the demand for freshly made pancakes, which may lead to the loss of some customers. When more griddles are added to increase the number of pancakes made, one staff member is needed to manage the production of multiple pancakes at the same time. This can easily lead to inconsistent pancake production times, affecting quality. Alternatively, having multiple staff members to manage the production can also increase production costs.

[0033] To address the above problems, the present invention provides the following specific implementation methods:

[0034] refer to Figure 1 , Figure 2 and Figure 4This invention provides a pancake maker, including a worktable 1, a griddle 2, and a pancake rake 3 for spreading batter. The bottom of the griddle 2 is equipped with heating modules 4 for heating the griddle 2. The number of heating modules 4 is multiple, and the number of griddles 2 corresponds to the number of heating modules 4. The maker also includes: a placement tray 5, a horizontal plate 6, a drive module 9, a dough feeding module 10, and a pancake scraping module 11. The placement tray 5 is located on the upper part of the worktable 1 and is rotatably connected to the worktable 1. Multiple heating modules 4 are evenly arranged along the perimeter of the upper surface of the placement tray 5. Multiple griddles 2 are connected one-to-one to the upper part of each heating module 4. The pancake rake 3 is located above one of the griddles 2. The horizontal plate 6 is connected to the worktable 1 via a lifting assembly 7. The vertical handle of the pancake rake 3 passes through the horizontal plate. A horizontal plate 6 is rotatably connected to the other two. A vertical handle is connected to a first motor 8 and a drive module 9, which is connected to the placement tray 5 to control the intermittent rotation of the placement tray 5 so that the pancake rake 3 is positioned above the corresponding griddle 2 each time it rotates. A dough feeding module 10 is connected to the operating table 1. The discharge port of the dough feeding module 10 is aligned with the middle of the griddle 2 below the pancake rake 3. The dough feeding module 10 is used to intermittently feed the batter to each griddle 2. A pancake shoveling module 11 is fixedly connected to the operating table 1. The pancake shoveling module 11 is located above the adjacent griddle 2 of the griddle 2 corresponding to the pancake rake 3. The pancake shoveling module 11 is used to shovel the spread pancake off the griddle 2. When the placement tray 5 rotates, the griddle 2 from which the pancake is shoveled rotates to the position corresponding to the pancake rake 3.

[0035] In the above embodiments, there are six heating modules 4, evenly distributed on the placement tray 5. The number of griddles 2 also corresponds to the number of heating modules 4, ensuring the simultaneous production of six pancakes on multiple griddles 2. This speeds up pancake production and improves efficiency. Furthermore, by controlling the temperature of the heating modules 4, the pancakes are perfectly formed after the placement tray 5 completes one rotation. Specifically, the heating module 4 is a rectangular heating base, with a PT100 platinum resistance sensor for constant temperature control. Utilizing its temperature-sensing effect, the thermal resistance changes with the ambient temperature. The 100 after PT indicates that its resistance is 100 ohms at 0℃ and approximately 138.5 ohms at 100℃, with the resistance increasing approximately uniformly as the temperature rises. When the temperature is below 135℃, the heating continues; when the temperature is above 150℃, heating stops. This sets the temperature range to 135℃-150℃, allowing the temperature to be adjusted within this range to the optimal temperature for making pancakes. The pancake rake 3 is used to rotate and flatten the pancake on the griddle 2, ensuring full contact between the pancake and the griddle surface. The pancake rake 3 is raised and lowered via the horizontal plate 6 and the lifting assembly 7. When it is necessary to flatten the pancake on the griddle 2, the lifting assembly 7 is lowered, and this is achieved by driving the first motor 8. Specifically, to improve the stability of the rotary drive, two meshing gears are fixedly connected to the output shaft of the first motor 8 and the vertical handle of the pancake rake 3. The drive module 9 is used to control the placement plate 5 to rotate 60° each time, thereby ensuring that the griddle 2 rotates at the same angle each time. This ensures the accuracy of the operation of the dough feeding module 10, the pancake rake 3, the oil brushing module 12, and the pancake shoveling module 11. It enables uninterrupted coordination of the modules, allowing for continuous pancake production. This reduces labor costs and achieves fully automated production, greatly improving production efficiency.

[0036] Further, refer to Figure 3 There is a distance between the placement tray 5 and the operating table 1. A sleeve 13 is fixedly connected to the lower middle part of the placement tray 5. The lower end of the sleeve 13 is rotatably connected to the operating table 1. The drive module 9 includes a drive motor 91. A first gear 92 is fixedly connected to the output end of the drive motor 91. A second gear 131 is fixedly fitted on the sleeve 13. The first gear 92 and the second gear 131 mesh with each other. The drive motor 91 is a stepper motor.

[0037] In the above embodiments, the drive motor 91 is able to control the rotation angle, and the rated rotation angle is adjusted to 60° each time. The output end of the drive motor 91 meshes with the second gear 131 through the first gear 92, driving the sleeve 13 and the placement disk 5 to rotate. Figure 1 As shown, the placement tray 5 can be rotated counterclockwise each time. After the feeding and flattening operations are completed, it can be rotated 60°, eliminating the need for manual rotation of the placement tray 5 and achieving mechanization and automation.

[0038] Further, refer to Figure 1 and Figure 5 The dough feeding module 10 includes: a dough cylinder 101, a partition 102, a feeding pipe 104, a placement plate 105, and a fixing column 106. The dough cylinder 101 has an opening at the top. The partition 102 is fixedly connected to the middle of the dough cylinder 101. The partition 102 is conical in shape, and the bottom of the cone is connected to a feeding control valve 103. The inlet end of the feeding pipe 104 is connected to the outlet end of the feeding control valve 103. The feeding pipe 104 horizontally penetrates the bottom of the dough cylinder 101 and extends towards the pancake rake 3. The outlet of the feeding pipe 104 faces downward and is located above the scraper of the pancake rake 3. The placement plate 105 is fixedly connected to the lower end of the dough cylinder 101. A through hole 51 is vertically opened in the middle of the placement plate 5. The fixing column 106 is fixedly connected to the bottom of the placement plate 105 and passes through the through hole 51 and the middle of the sleeve 13. The lower end of the fixing column 106 is fixedly connected to the operating table 1.

[0039] In the above embodiments, the batter cylinder 101 can convey batter to the griddle 2 through the feed pipe 104. Specifically, the feed control valve 103 is an electric control valve of model CV3000. The actuator of the CV3000 electric control valve is equipped with a position sensor. By detecting the valve opening, it feeds the sensor back to the controller. The controller compares the valve opening with the desired opening and then adjusts the output of the motor according to the error value so that the valve reaches the desired opening. This allows for precise control of the feed amount, which is then conveyed to the corresponding middle position of the griddle 2 through the feed pipe 104 in a rated amount.

[0040] Further, refer to Figure 4 The lifting assembly 7 includes a base plate 71, which is fixedly connected to the operating table 1. Multiple electric telescopic rods 72 are provided between the base and the horizontal plate 6. The fixed end of the electric telescopic rod 72 is fixedly connected to the horizontal plate 6, and the telescopic end of the electric telescopic rod 72 is fixedly connected to the base plate 71.

[0041] In the above embodiments, the output end of the electric telescopic rod 72 continuously extends and retracts to drive the height of the pancake rake 3 to rise and fall. When the dough conveying module 10 conveys the batter to the griddle 2 through the conveying pipe 104, it controls the pancake rake 3 to move downwards towards the batter and rotate to spread it flat, thus eliminating the manual pancake spreading process.

[0042] Further, refer to Figure 4 It also includes a horizontal plate 14, the other end of which is located between the griddle 2 and the pancake rake 3. The horizontal plate 14 has a material blocking hole 141 vertically opened along the outer diameter of the griddle 2. The material blocking hole 141 is larger than the scraper length of the pancake rake 3. The material blocking hole 141 is used to block the spread batter and prevent the batter from falling off the edge of the griddle 2. A height adjustment component 15 is provided on one side of the horizontal plate 14.

[0043] In the above embodiments, the batter can be prevented from falling off by the baffle hole 141, and the adjustment component 15 is used to make the horizontal plate 14 approach and stick to the upper surface of the griddle 2. When the pancake rake 3 spreads the batter, the batter is difficult to fall off.

[0044] Further, refer to Figure 4 The adjusting assembly 15 includes a screw 151, which passes vertically through the horizontal plate 14 and is threadedly connected to it. One end of the screw 151 is connected to a second motor 16, and the mounting base of the second motor 16 is fixedly connected to the lower end face of the horizontal plate 6. The other end of the screw 151 is rotatably connected to the base plate 71. The outer cylinder of the fixed end of the electric telescopic rod 72 passes through the horizontal plate 14 and is slidably connected to the horizontal plate 14.

[0045] In the above embodiments, the lifting and lowering of the horizontal plate 14 is mainly achieved by the drive of the empty second motor 16 to rotate the screw 151. Since the screw 151 and the horizontal plate 14 are threadedly connected, the height of the horizontal plate 14 will rise or fall after the output end of the second motor 16 rotates. When the dough feeding module 10 feeds dough onto the griddle 2, the second motor 16 controls the horizontal plate 14 to move closer to and stick tightly to the griddle 2. After the pancake is flattened, the griddle 2 with the pancake flattened needs to be rotated to the next angle so that when the empty griddle 2 of the pancake shovel module 11 feeds dough, the second motor 16 controls the horizontal plate 14 to rise slightly. After the placement plate 5 rotates 60° in the opposite direction, the horizontal plate 14 is then controlled to move down and stick tightly to the empty griddle 2 again, thereby achieving a fully automated effect.

[0046] Further, refer to Figure 1 and Figure 6 The pancake shovel module 11 includes a connecting frame 111, which is fixedly connected to the upper end of the operating table 1. A horizontal slide rail 112 is fixedly connected to one side of the connecting frame 111. A slide plate 113 is slidably connected inside the slide rail 112. A lead screw 114 is horizontally inserted into the slide plate 113 and the two are threaded together. Both ends of the lead screw 114 are slidably connected to the slide rail 112. One end of the lead screw 114 is connected to a third motor 115. A pancake shovel 116 is connected to one side of the slide plate 113. The blade of the pancake shovel 116 is flush with the upper surface of the griddle 2. The initial position of the pancake shovel 116 is close to the side of the pancake rake 3. When the slide plate 113 slides horizontally, the pancake shovel 116 can scoop the spread pancakes out of the placement plate 5 and return to the initial position to scoop the next pancake from the griddle 2, thereby achieving a fully automated effect.

[0047] Further, refer to Figure 1 and Figure 7The oiling module 12 is connected to the pancake shovel module 11 and is used to brush oil onto the griddle 2 after the pancake is removed. The oiling module 12 is fixedly connected to the slide plate 113 via the fixing bracket 121. The oiling module 12 includes an oil hopper 122. An oil supply control valve 123 is connected to the bottom of the oil hopper 122. An oil supply pipe 124 is connected to the outlet of the oil supply control valve 123. A brush 125 is connected to the outlet of the oil supply pipe 124. The brush 125 is located between the pancake shovel 116 and the pancake rake 3. When the pancake shovel 116 removes the pancake, the brush 125 with oil will move synchronously to brush oil onto the griddle 2 after the pancake is removed. When the pancake shovel 116 returns to the initial position, the brush 125 brushes oil onto the griddle 2 again. After brushing oil, the griddle 2 is rotated by the placement plate 5 to the position of the pancake rake 3 to feed and flatten the pancake.

[0048] In the above embodiments, specifically, the oil delivery control valve 123 is also an electric control valve of model CV3000. The actuator of the CV3000 electric control valve is equipped with a position sensor. By detecting the valve opening, it feeds the sensor back to the controller. The controller compares the valve opening with the desired opening and then adjusts the output of the motor according to the error value so that the valve reaches the desired opening, thereby enabling precise control of the feed rate.

[0049] Further, refer to Figure 1 and Figure 8 The worktable 1 is located below the pancake shovel 116 and is equipped with a belt conveyor 17 for catching and conveying the pancakes.

[0050] In the above embodiments, the belt conveyor 17 is able to transport pancakes that fall onto the conveyor belt by gravity and deliver them to a designated collection location.

[0051] The achieved effects are as follows: This invention has modular features, which can realize the production of multiple pancakes, specifically including functions such as oil conveying, dough conveying, dough spreading, pancake shoveling, and conveying. The entire automatic pancake machine is divided into independent functional parts. This invention has integrated features, which bring together the various structures to jointly realize the function of pancake making. This invention has standardized features, which, except for parts with special instructions, all parts adopt the specified standard parts, which can meet the production needs of various small enterprises.

[0052] Usage and working principle: When using, first adjust the height of the pancake shovel 116 in the pancake shovel module 11 and make it flush with the upper surface of the griddle 2. Then fill the batter into the batter cylinder 101 and the oil into the oil hopper 122.

[0053] After filling the pancake maker with batter and oil, press the start switch to start the automatic pancake maker. Once powered on, the heating module 4 under the griddle 2 uses a PT100 platinum resistance sensor to maintain a constant temperature. Utilizing the temperature sensing effect of the PT100 platinum resistance sensor, the heating temperature range is kept between 135-150℃. The specific temperature can be adjusted by the knob until the optimal temperature for making pancakes is reached.

[0054] Once the optimal temperature is reached, the second motor 16 drives the screw 151 to rotate, thereby adjusting the height of the horizontal plate 14 so that it completely fits the griddle 2. The baffle hole 141 ensures that the batter does not overflow from the griddle 2. At the same time, the amount of batter dispensed is adjusted by the CV3000 electric feeding control valve 103 in the batter bucket to ensure that each portion of batter is evenly distributed. The batter is then transported to the griddle 2 through the feeding pipe 104. At this time, the electric telescopic rod 72 is controlled to lower the pancake rake 3. During the descent, the first motor 8 is activated, causing the pancake rake 3 to rotate. As the height of the pancake rake 3 decreases, the batter delivered to the griddle 2 is evenly spread during the rotation process.

[0055] After the pancake is flattened and shaped, the second motor 16 is controlled to rotate in the opposite direction, causing the horizontal plate 14 to rise vertically. Simultaneously, the output end of the electric telescopic rod 72 is extended, slightly raising the height of the pancake rake 3 and positioning it below the outlet of the conveying pipe 104. Figure 1 As shown, at this time, the control drive motor 91 uses the meshing of the first gear 92 and the second gear 131 to drive the sleeve 13 and the placement plate 5 to rotate counterclockwise by 60° to enter the next process. At the same time, before the batter is fed onto the first griddle 2, the pancake shovel module 11 and the oil brushing module 12 also correspond to an empty griddle 2. At this time, the oil supply control valve 123 and the third motor 115 of the pancake shovel module 11 are opened. The oil enters the oil brush through the oil supply pipe 124. With the reciprocating motion of the slide plate 113 on the slide rail 112, the empty griddle 2 is evenly brushed on the surface of the griddle 2. Then the placement plate 5 is controlled to rotate counterclockwise by 60° to start feeding and smoothing the surface of the oiled griddle 2.

[0056] After the first griddle 2 with a pancake on it rotates once, it reaches the pancake shovel 116 of the pancake shovel module 11. At this time, the pancake on the griddle 2 is ready, and the pancake shovel 116 will be located on the side closer to the griddle 2. Then, under the control of the lead screw 114 and the third motor 115, the pancake shovel 116 is lifted off the griddle 2 from left to right. The griddle 2 falls onto the belt conveyor 17 and is collected. While the pancake shovel 116 is shoveling from left to right, the brush 125 will also brush a layer of oil on the upper surface of the griddle 2. When the pancake shovel 116 returns to its initial position close to the griddle 2, the pancake removal step is completed.

[0057] Therefore, uninterrupted coordination and continuous pancake production can be achieved, reducing labor costs while realizing fully automated production and greatly improving production efficiency.

[0058] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
