Description

Technical Field

[0001] The invention belongs to the technical field of food processing, and in particular relates to an integrated automatic production and processing device for instant dumplings. Background Art

[0002] With the accelerated pace of people's lives and the increasing demand for convenience foods, instant dumplings, as a convenient and delicious food, are in increasing market demand. The traditional method of making dumplings by hand is inefficient and difficult to meet the needs of large-scale production. In addition, the labor cost is high, and the quality of the finished product will vary depending on the operator, affecting the consistency and aesthetics of the product.

[0003] In order to improve production efficiency and reduce costs, some automated dumpling production equipment has appeared on the market, which can automate some processes, such as automatic skin pressing and automatic stuffing injection.

[0004] However, although the existing automated production and processing equipment for instant dumplings can complete some processes when in use, the links are not connected smoothly. For example, the dough conveying and stuffing and wrapping processes are poorly coordinated, and problems such as dumpling skin breakage and stuffing overflow often occur. In addition, the pre-cooking and quick cooling links lack an efficient processing mechanism, which affects the taste and shelf life of the dumplings. Therefore, there is an urgent need to develop an efficient, precise, and highly automated instant dumpling production equipment. Summary of the Invention

[0005] In response to the above-mentioned problems, the present invention discloses an integrated automatic production and processing equipment for instant dumplings.

[0006] The technical solution of the present invention is: an integrated instant dumpling automated production and processing equipment, comprising a frame, a first conveyor belt provided on the frame, a dough processing unit distributed along the length direction of the first conveyor belt, a stuffing injection unit, a dumpling wrapping and forming unit, a pre-cooking unit, and a quick cooling unit;

[0007] The pre-cooking unit includes a blanching box located at the unloading end of the first conveyor belt and provided with a downwardly inclined material guide platform inside, a vertical mounting rod provided at one side of the blanching box and driven to rotate by a motor, a plurality of vertical side plates circumferentially arranged on the side walls of the vertical mounting rod, a rotating main frame provided on each vertical side plate and with a plurality of horizontal support rods evenly arranged on the side walls along the circumference, a mesh pre-cooking frame rotatably connected to each of the horizontal support rods, two horizontal sliding plates connected to the front and rear sides of the blanching box at the bottom ends by connecting rods, a toggle plate that can slide left and right along the two horizontal sliding plates and is used to toggle the mesh pre-cooking frame to rotate, the rotating main frame is driven to rotate by a motor, and each vertical side plate can slide up and down along the vertical mounting rod;

[0008] The quick cooling unit includes a second conveyor belt and a quick cooling box placed on the second conveyor belt and provided with a dumpling holding plate therein.

[0009] Furthermore, the dough processing unit includes a first mounting frame obliquely arranged on one side of the frame, a third conveyor belt arranged on the first mounting frame, a second mounting frame arranged on the first mounting frame along the width direction, a dough kneading device arranged at the bottom end of the second mounting frame, a dough pressing roller located at the lower end of the dough kneading device, a third mounting frame arranged on the frame along the width direction, a horizontal mounting plate connected to the bottom end of the third mounting frame through an electric telescopic rod, and a plurality of dough pressing covers distributed in a matrix shape.

[0010] Description: When the dough processing unit is in use, flour and water are added to the dough kneading device. The rotation and extrusion action of the dough kneading device simulates the method of manual kneading and fully kneads to form dough. Then, the dough in the dough kneading device is received by the dough pressing roller and gradually pressed into dough sheets with uniform thickness, providing a good foundation for subsequent skin pressing operations. The two work together to flexibly adjust the texture and thickness of the dough according to different dumpling requirements. The pressed dough sheets are conveyed to the first conveyor belt on the frame through the third conveyor belt. The matrix-shaped skin pressing covers are driven by the electric telescopic rod to press down accurately and press the dough sheets into several dumpling wrappers. At the same time, skin pressing covers of different specifications can adapt to various dumpling sizes to meet diversified production needs. By simulating manual kneading and realizing precise sheeting and skin pressing through automation, the production efficiency is greatly improved while ensuring or even improving the quality of the dumpling wrappers.

[0011] Furthermore, the filling injection unit includes a filling injection mounting frame arranged on the frame along the width direction and provided with through-holes corresponding to the leather pressing covers at the upper end, an adding temporary storage cylinder installed at each of the through-holes and provided with a feeding pipe at the bottom end, a quantitative extrusion cylinder connected to the bottom end of the feeding pipe, a rotating screw arranged in the quantitative extrusion cylinder and driven by a micro motor, and an electromagnetic valve is provided at the bottom end of the quantitative extrusion cylinder.

[0012] Description: When the filling unit is in use, the pressed dumpling wrappers are conveyed to the lower end of each quantitative extrusion cylinder through the first conveyor belt, and dumpling fillings are continuously added to each temporary storage cylinder. The temporary storage cylinder acts as a temporary buffer. At the same time, the micro motor is started, and the corresponding rotating screw is driven by the micro motor to rotate, so that the dumpling fillings that fall from the temporary storage cylinder into the quantitative extrusion cylinder are rotated and extruded. The extrusion amount of the filling is controlled by the precise number of rotations. In conjunction with the solenoid valve at the bottom, the filling can be quantitatively, accurately and stably conveyed, ensuring that the filling amount of each dumpling is the same, thereby improving the stability of product quality.

[0013] Furthermore, the inner wall of the quantitative extrusion cylinder is provided with an anti-stick coating.

[0014] Note: The anti-stick coating on the inner wall of the quantitative extrusion cylinder is made of food-grade non-stick material, which effectively prevents the dumpling filling from sticking and ensures smooth filling delivery.

[0015] Furthermore, the dumpling wrapping and forming unit includes two vertical mounting plates arranged on the front and rear sides of the frame along the width direction, two horizontal mounting plates distributed parallel to the two vertical mounting plates, several adsorption plates connected to the bottom end of the horizontal mounting plate located on the upper side in a matrix shape, a wrapper provided on the horizontal mounting plate located on the lower side and corresponding one-to-one to the adsorption plates, and the adsorption plates are connected to a negative pressure air pump through an air pipe. The horizontal mounting plate located on the upper side can slide up and down along the vertical mounting plate, and the horizontal mounting plate located on the lower side can slide back and forth along the vertical mounting plate.

[0016] Description: When the dumpling wrapping and forming unit is in use, the dumplings with dumpling stuffing are conveyed to the bottom end of the horizontal mounting plate through the first conveyor belt, and the horizontal mounting plate on the upper side is slid downward to make the adsorption plate move downward and contact the corresponding edge of the dumpling wrapper. At this time, the adsorption plate generates strong suction through the negative pressure air pump, which can firmly adsorb the pressed dough to prevent the dough from slipping or shifting during the movement and wrapping process. Then, the horizontal mounting plate is slid upward to realize the grabbing and placing action of the adsorption plate on the dough. The horizontal mounting plate on the lower side can slide back and forth along the vertical mounting plate, driving the wrapper and the adsorption plate to cooperate to complete the wrapping of the dumplings. The movement is coordinated by a precise control system, and the movement is smooth and precise, which can efficiently complete the automated wrapping of dumplings, and the dumplings wrapped have regular shapes and tight seals.

[0017] Furthermore, the toggle plate is provided with a snap-fitting recess for fitting with the outer wall of the mesh pre-cooked frame, and the inner wall of the snap-fitting recess is provided with a magnetic layer.

[0018] Description: When the motor drives the rotating main frame to rotate, the mesh pre-cooking frame connected to each horizontal support rod rotates synchronously. When the mesh pre-cooking frame rotates into the blanching box, the dumplings are pre-cooked, which helps to naturally separate the dumplings that may be in contact, further reducing the risk of adhesion, and avoiding damage caused by violent collisions. When the dumplings in the mesh pre-cooking frame are pre-cooked, they will rotate to the toggle plate. At this time, the toggle plate is driven to move toward the side close to the mesh pre-cooking frame until the engaging recess contacts the outer wall of the mesh pre-cooking frame and pushes it to rotate, so that the dumplings in the mesh pre-cooking frame are turned over into the quick-cooling box. Then, the quick-cooling box full of dumplings can be moved out by the second conveyor belt to ensure the smooth transfer of the dumplings.

[0019] Furthermore, the inner wall of the mesh holes of the mesh pre-cooking frame is coated with an anti-sticking layer, and a counterweight is provided at the bottom of the mesh pre-cooking frame, and the material of the anti-sticking layer is polytetrafluoroethylene.

[0020] Description: The anti-stick layer coated on the inner wall of the mesh pre-cooking frame is made of polytetrafluoroethylene, which has excellent non-stick properties and can effectively prevent the dumplings from sticking to the mesh pre-cooking frame during the pre-cooking process, making it convenient for subsequent removal and processing. The counterweight block can ensure that the mesh pre-cooking frame always maintains a stable posture during the blanching process, so that the dumplings are evenly heated in the mesh pre-cooking frame, improving the pre-cooking effect. At the same time, it can also ensure that the opening of the mesh pre-cooking frame is always at the upper end to prevent dumplings from falling out during rotation.

[0021] Furthermore, an inner wall of the dumpling stacking box is provided with an elastic buffer layer, and the elastic buffer layer is made of rubber material. The second conveyor belt is a vibrating conveyor belt, and the surface of the second conveyor belt is provided with anti-slip convex grooves.

[0022] Note: The second conveyor belt is a vibrating conveyor belt. The anti-slip ridges on its surface increase the friction between it and the rapid cooling box, preventing the dumpling holding plate from sliding or shifting during the vibration conveying process. The vibration function can evenly distribute the dumplings on the dumpling holding plate during the conveying process, avoiding accumulation and facilitating subsequent rapid cooling.

[0023] Furthermore, a plurality of adjustable supporting feet are provided at the bottom ends of the frame and the first mounting frame, a rubber anti-slip cover is provided at the bottom end of each adjustable supporting foot, and an anti-slip bump is provided at the bottom end of the rubber anti-slip cover.

[0024] Note: The adjustable support feet at the bottom of the frame and the first mounting bracket can be adjusted in height according to different ground conditions to ensure stable installation of the equipment and avoid vibration during equipment operation due to uneven ground, which affects production accuracy and equipment life. The rubber anti-slip sleeve and the anti-slip bumps at the bottom further enhance the stability of the equipment, prevent the equipment from displacement during operation, and ensure production safety.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] (1) The integrated instant dumpling automated production and processing equipment of the present invention integrates the whole process functions of dough processing, stuffing injection, wrapping and shaping, pre-cooking and rapid cooling when in use. Through the coordinated operation of each unit, the production of instant dumplings is highly automated. From flour input to the output of finished dumplings, there is no need for excessive human intervention, which greatly reduces labor costs and significantly improves production efficiency, and can meet the needs of large-scale industrial production. The dough processing unit can flexibly adjust the dough texture and dough thickness by cooperating with the dough kneading device and the dough pressing roller; the stuffing injection unit uses a rotating screw and a solenoid valve to accurately control the amount of filling extrusion; the dumpling wrapping and shaping unit ensures that the dumplings are regular in shape and tightly sealed through the precise cooperation of the adsorption plate and the wrapping device; the pre-cooking unit adopts a mesh pre-cooking frame with a rotating main frame and a toggle plate design, so that the dumplings are naturally separated during the pre-cooking process to avoid adhesion and breakage. At the same time, the counterweight block and the anti-sticking layer ensure the pre-cooking effect and cleaning convenience; the vibrating conveyor belt and elastic buffer layer design of the rapid cooling unit make the dumplings evenly distributed during the transportation process, prevent accumulation, and improve cooling efficiency and product quality;

The rubber anti-slip cover 11 and the anti-slip convex point 12 at the bottom further enhance the stability of the equipment, prevent the equipment from moving during operation, and ensure production safety. Among them, the adjustable support feet 10 adopt a mechanical support foot of model M16;

[0040] like Figure 2 、 3As shown, the dough processing unit 3 includes a first mounting frame 30 inclined at one side of the frame 1, a third conveyor belt 31 arranged on the first mounting frame 30, a second mounting frame 32 arranged on the first mounting frame 30 along the width direction, a dough kneading device 33 arranged at the bottom end of the second mounting frame 32, a dough pressing roller 34 at the lower end of the dough kneading device 32, a third mounting frame 35 arranged on the frame 1 along the width direction, a horizontal mounting plate 36 connected to the bottom end of the third mounting frame 35 through an electric telescopic rod 360, and 9 dough pressing covers 37 distributed in a matrix shape. When the dough processing unit 3 is in use, flour and water are added to the dough kneading device 33, and the dough kneading device 33 is rotated and squeezed to simulate the manual kneading method, and the dough is fully kneaded to form dough. Then, the dough pressing roller 34 receives the dough in the dough kneading device 33 and gradually presses it into a dough sheet with uniform thickness, providing a good foundation for subsequent dough pressing operations. The two cooperate to flexibly adjust the dough thickness according to different dumpling requirements. The texture of the dough and the thickness of the dough sheet are determined by the third conveyor belt 31 and the pressed dough sheet is conveyed to the first conveyor belt 2 on the frame 1. The matrix-shaped pressing cover 37 is driven by the electric telescopic rod 360 to accurately press down and press the dough sheet into several dumpling wrappers. At the same time, the pressing covers 37 of different specifications can adapt to a variety of dumpling sizes to meet diversified production needs. By simulating manual dough kneading and achieving accurate sheeting and pressing, the production efficiency is greatly improved while ensuring or even improving the quality of the dumpling wrappers. Among them, the dough kneading device 33, the dough pressing roller 34, the electric telescopic rod 360 and the dough pressing cover 37 all adopt existing technologies. For example, the dough kneading device 33 can adopt the HM740 dough kneading device, the dough pressing roller 34 can adopt the roller model YQ-Y110A, the electric telescopic rod 360 can adopt the electric telescopic rod model Y4-236, and the dough pressing cover 37 can adopt a dough pressing cover similar to the Hillqiang XEQ-5KW high-frequency embossing machine.

[0041] like Figure 4 、 5As shown, the filling unit 4 includes a filling installation frame 40 which is arranged on the frame 1 along the width direction and has a through-hole 400 corresponding to the skin pressing cover 36 at the upper end, an adding temporary storage cylinder 41 which is installed at each through-hole 400 and has a feeding pipe 410 at the bottom end, a quantitative extrusion cylinder 42 connected to the bottom end of the feeding pipe 410, a rotating screw 43 which is arranged in the quantitative extrusion cylinder 42 and driven by a micro motor, and an electromagnetic valve 420 is provided at the bottom end of the quantitative extrusion cylinder 42. When the filling unit 4 is in use, the pressed dumpling skin is conveyed to the lower end of each quantitative extrusion cylinder 42 through the first conveyor belt 2, and dumpling stuffing is continuously added to each adding temporary storage cylinder 41. The adding temporary storage cylinder 41 plays a role in The function of temporary storage and buffering is achieved. At the same time, the micro motor is started, and the corresponding rotating screw 43 is driven by the micro motor to rotate, so that the dumpling filling dropped from the temporary storage cylinder 41 to the quantitative extrusion cylinder 42 is rotated and extruded. The extrusion amount of the filling is controlled by the precise number of rotations. In conjunction with the solenoid valve 420 at the bottom, the filling can be quantitatively, accurately and stably conveyed, ensuring that the amount of filling in each dumpling is the same, thereby improving the stability of product quality. Among them, the rotating screw 43, the solenoid valve 420 and the micro motor all adopt existing technologies. For example, the rotating screw 43 can adopt a precision ball screw with a model number of SFU1605-4, the solenoid valve 420 can adopt a solenoid valve with a model number of urkert 0330, and the micro motor can adopt a micro motor with a model number of FF-K10WA-5Z215.

[0042] The inner wall of the quantitative extrusion cylinder 42 is provided with an anti-stick coating, which is made of food-grade PTFE coating material to effectively prevent the dumpling filling from sticking and ensure smooth delivery of the filling;

[0043] like Figure 6 、 7As shown, the dumpling wrapping and forming unit 5 includes two vertical mounting plates 50 arranged on the front and rear sides of the frame 1 along the width direction, two horizontal mounting plates 51 distributed parallel to the two vertical mounting plates 50, 9 adsorption plates 52 connected to the bottom end of the horizontal mounting plate 51 on the upper side in a matrix shape, a wrapper 53 arranged on the horizontal mounting plate 51 on the lower side and corresponding to the adsorption plates 52 one by one, and the adsorption plates 52 are connected to a negative pressure air pump through an air pipe. The horizontal mounting plate 51 on the upper side can slide up and down along the vertical mounting plate 50, and the horizontal mounting plate 51 on the lower side can slide back and forth along the vertical mounting plate 50. When the dumpling wrapping and forming unit 5 is in use, the dumplings with dumpling stuffing are transported to the bottom end of the horizontal mounting plate 51 by the first conveyor belt 2, and the horizontal mounting plate 51 on the upper side is slid downward to make the adsorption plates 52 move downward and contact the corresponding edge of the dumpling wrapper. The suction plate 52 is touched, at this time, the negative pressure air pump generates a strong suction force to firmly absorb the pressed dough to prevent the dough from slipping or shifting during the movement and wrapping process. Then, the horizontal mounting plate 51 is slid upward to realize the grabbing and placing action of the suction plate 52 on the dough. The horizontal mounting plate 51 located at the lower side can slide back and forth along the vertical mounting plate 50, driving the wrapper 53 to cooperate with the suction plate to complete the wrapping of dumplings. The precise control system coordinates the movement, the movement is smooth and accurate, and the automatic wrapping of dumplings can be completed efficiently. The dumplings wrapped are regular in shape and tightly sealed. Among them, the suction plate 52, the wrapper 53, and the negative pressure air pump all adopt existing technologies. The suction plate 52 can adopt the suction plate of model SSD-20, the wrapper 53 can adopt the wrapper of model JZP-200, and the negative pressure air pump can adopt the existing integrated vacuum pump.

[0044] like Figure 8 As shown, the pre-cooking unit 6 includes a blanching box 61 located at the unloading end of the first conveyor belt 2 and provided with a downwardly inclined material guide platform 60 inside, a vertical mounting rod 62 arranged at one side of the blanching box 61 and driven to rotate by a motor, three vertical side plates 63 circumferentially arranged on the side walls of the vertical mounting rod 62, a rotating main frame 65 provided on each vertical side plate 63 and with four horizontal support rods 650 evenly arranged on the side walls along the circumference, a mesh pre-cooking frame 66 rotatably connected to each horizontal support rod 65, two horizontal sliding plates 67 connected to the front and rear sides of the blanching box 61 at the bottom end by a connecting rod, a toggle plate 68 that can slide left and right along the two horizontal sliding plates 67 and is used to toggle the mesh pre-cooking frame 66 for rotation, the rotating main frame 65 is driven to rotate by a motor, and each vertical side plate 63 can slide up and down along the vertical mounting rod 62, wherein the motor adopts the existing technology, for example, a motor of model RS-380 can be adopted;

[0045] The quick cooling unit 7 includes a second conveyor belt 71, a quick cooling box 72 placed on the second conveyor belt 71 and provided with a dumpling holding plate 720 inside, wherein the first conveyor belt 2, the third conveyor belt 31 and the second conveyor belt 71 all adopt existing technology, for example, a food-grade PVC conveyor belt with model TPU-PVC-600 can be used.

[0046] Example 2: This example discloses an automated production and processing method for instant dumplings, based on an integrated automated production and processing device for instant dumplings according to Example 1, comprising the following steps:

[0047] S1. Add flour and water into the dough kneading device 33. The dough kneading device 33 rotates and squeezes to simulate manual kneading, and fully kneads the dough to form dough. Then, the dough pressing roller 34 receives the dough in the dough kneading device 33 and gradually presses it into a dough sheet with uniform thickness. The pressed dough sheet is conveyed to the first conveyor belt 2 on the frame 1 via the third conveyor belt 31. The matrix-shaped pressing covers 37 are driven by the electric telescopic rod 360 to press down accurately to press the dough sheet into a plurality of dumpling wrappers.

[0048] S2. The pressed dumpling wrappers are conveyed to the lower end of each quantitative extrusion cylinder 42 via the first conveyor belt 2, and dumpling fillings are continuously added to each temporary adding cylinder 41. The temporary adding cylinder 41 acts as a temporary buffer. At the same time, the micro motor is started, and the corresponding rotating screw 43 is driven by the micro motor to rotate, so that the dumpling fillings dropped from the temporary adding cylinder 41 into the quantitative extrusion cylinder 42 are rotated and extruded. The extrusion amount of the fillings is controlled by the precise number of rotations, and the electromagnetic valve 420 at the bottom is used to ensure that the filling amount of each dumpling is the same;

[0049] S3. The dumplings with the dumpling filling are conveyed to the bottom end of the horizontal mounting plate 51 via the first conveyor belt 2. The upper horizontal mounting plate 51 is slid downward, causing the suction plate 52 to move downward and contact the corresponding edge of the dumpling wrapper. At this time, the suction plate 52 generates a strong suction force through the negative pressure air pump, which can firmly adsorb the pressed dough wrapper. Then, the horizontal mounting plate 51 is slid upward to achieve the suction plate 52 grabbing and placing the dough wrapper. The lower horizontal mounting plate 51 can slide back and forth along the vertical mounting plate 50, driving the wrapper 53 to cooperate with the suction plate to complete the dumpling wrapping.

[0050] S4, the wrapped part of the dumplings is transported to the guide table 60 through the first conveyor belt 2. At the same time, the vertical mounting rod 62 is driven by the motor to rotate, and it rotates to the upper end of the blanching box 61 through one of the vertical side plates 63. Then, the corresponding rotating main frame 65 is driven by the motor at each vertical side plate 63 to rotate, so that one of the mesh pre-cooking frames 66 on the rotating main frame 65 is rotated to the lower end of the guide table 60. At this time, some of the dumplings transported to the guide table 60 will fall into the mesh pre-cooking frame 66. Since the rotating main frame 65 is continuously rotating, the guide table The dumplings at 60 will fall into each mesh pre-cooking frame 66 in turn, and each mesh pre-cooking frame 66 will be rotated to the blanching box 61 for pre-cooking. When each mesh pre-cooking frame 66 on one of the vertical side plates 63 is full of dumplings and pre-cooking is completed, the remaining dumplings are transported to the guide table 60 by the first conveyor belt 2, and the above steps are repeated to rotate the other vertical side plate 63 to the upper end of the blanching box 61, and fill the corresponding mesh pre-cooking frames 66 on the vertical side plate 63 with dumplings and pre-cook until all dumplings are processed.

[0051] S5. When the dumplings in the mesh pre-cooking frame 66 are pre-cooked, they will rotate to the toggle plate 68. At this time, the toggle plate 68 is driven to move toward the side close to the mesh pre-cooking frame 66 and push the mesh pre-cooking frame 66 to rotate, so that the dumplings in the mesh pre-cooking frame 66 are turned over into the quick-cooling box 72. Then, the quick-cooling box 72 filled with dumplings can be moved out by the second conveyor belt 71.

[0052] Example 3: This example differs from Example 1 in that:

[0053] like Figure 8 As shown, the toggle plate 68 is provided with a snap-fitting notch 680 for fitting with the outer wall of the mesh pre-cooking frame 66, and the inner wall of the snap-fitting notch 680 is provided with a magnetic layer 681. When the dumplings in the mesh pre-cooking frame 66 are pre-cooked, they will rotate to the toggle plate 68. At this time, the toggle plate 68 is driven to move toward the side close to the mesh pre-cooking frame 66 until the snap-fitting notch 680 contacts the outer wall of the mesh pre-cooking frame 66 and pushes it to rotate, so that the dumplings in the mesh pre-cooking frame 66 are turned over to the quick-cooling box 72. Then, the quick-cooling box 72 filled with dumplings can be moved out by the second conveyor belt 71 to ensure the smooth transfer of the dumplings.

[0054] The mesh inner wall of the mesh pre-cooking frame 66 is coated with an anti-sticking layer, and a counterweight 661 is provided at the bottom of the mesh pre-cooking frame 66. The anti-sticking layer is made of polytetrafluoroethylene. The anti-sticking layer coated on the mesh inner wall of the mesh pre-cooking frame 66 is made of polytetrafluoroethylene and has excellent non-stick properties. It can effectively prevent the dumplings from sticking to the mesh pre-cooking frame 66 during the pre-cooking process, making it convenient for subsequent removal and processing. The counterweight 661 can ensure that the mesh pre-cooking frame 66 always maintains a stable posture during the blanching process, so that the dumplings are evenly heated in the mesh pre-cooking frame 66, thereby improving the pre-cooking effect. At the same time, it can also ensure that the opening of the mesh pre-cooking frame 66 is always located at the upper end, preventing the dumplings from falling out during the rotation process.

[0055] The inner wall of the dumpling stacking box 70 is provided with an elastic buffer layer, which is made of rubber material. The second conveyor belt 71 is a vibrating conveyor belt, and the surface of the second conveyor belt 71 is provided with anti-slip ridges. The second conveyor belt 71 is used as a vibrating conveyor belt, and the anti-slip ridges on the surface increase the friction between the second conveyor belt 71 and the quick cooling box 72 to prevent the dumpling holding plate 720 from sliding or shifting during the vibration conveying process. The vibration function can make the dumplings evenly distributed on the dumpling holding plate 720 during the conveying process, avoiding accumulation, which is conducive to subsequent rapid cooling.

[0056] Example 4: This example differs from Example 2 in that:

[0057] In step S4, when the motor drives the rotating main frame 65 to rotate, the mesh pre-cooking frame 66 connected to each horizontal support rod 650 rotates synchronously. When the mesh pre-cooking frame 66 rotates into the blanching box 61, the dumplings are pre-cooked. When the dumplings in the mesh pre-cooking frame 66 are pre-cooked, they will rotate to the toggle plate 68. At this time, the toggle plate 68 is driven to move toward the side close to the mesh pre-cooking frame 66 until the engaging recess 680 contacts the outer wall of the mesh pre-cooking frame 66 and pushes it to rotate, so that the dumplings in the mesh pre-cooking frame 66 are turned over into the quick-cooling box 72, and then the quick-cooling box 72 filled with dumplings can be moved out by the second conveyor belt 71.
