Description

Technical Field

[0001] The invention relates to the technical field of food processing, in particular to a method and a device for pressing and shaping a primary embryo of a stuffed food. Background Art

[0002] Stuffed foods are foods wrapped with fillings, such as steamed buns, dumplings, wontons, pies, moon cakes, glutinous rice balls, etc. When using food processing machinery to process and make these stuffed foods, it is usually necessary to first form a preliminary embryo during the process after filling and before kneading and shaping, that is, the outer skin with the filling is preliminarily processed, the outer skin is preliminarily bonded to completely wrap the filling, and then further kneading and shaping is performed.

[0003] For example, when sealing the wonton blanks on the automatic wonton machine, the folding device flips up from the bottom to fold the dough in half. This process cannot ensure that the dough at the sealing point fits tightly from top to bottom, and it is necessary to apply pressure on the folded blanks to make sure there is no obvious gap between the upper and lower layers of dough. The existing wonton blank processing device only has one group above the conveyor belt corresponding to the folding device, which presses the edge of the folded dough again to further reduce the gap between the upper and lower layers of dough.

[0004] Although this structure can ensure that the upper and lower layers of the stuffed food dough are attached to a certain extent when the stuffed food embryo is transported to the next process, compared with the separately installed folding device, it only has one pressing effect, and the contact surface between this fastening device and the dough is made of hard material, the position of the stuffing in the dough is relatively fixed, and it is impossible to trim the stuffed food before the final shaping. The stuffed food will eventually be formed with scattered stuffing and an incomplete overall shape. At the same time, the power lifting structure is relatively complicated, which increases the weight of the whole wonton machine, and the frame part connected to it is prone to deformation, which will also affect the pressing effect. Summary of the invention

[0005] The present invention provides a method and device for pressing and shaping a primary embryo of a stuffed food, which solves the problems that the dough skin is not tightly fitted after folding, the dough skin is easily moved due to the resetting of a folding device, and the filling inside is scattered, which affects the taste and appearance. The dough skin of the primary embryo of the stuffed food is tightly fitted, and the overall shape of the finished product is fuller.

[0006] In order to solve the above technical problems, the technical solution provided by the present invention is as follows: a method for pressing and shaping a stuffed food embryo, comprising installing a dough pressing device and a embryo shaping device on a dough conveyor with a folding device; the dough pressing device is located above the operating position of the folding device, and is used to press and fix the stuffed food embryo formed by folding the dough by the folding device, and the embryo shaping device is located at the operating position behind the dough pressing device, and is used to shape the filling in the stuffed food embryo; while the folding device folds the dough pre-filled with fillings and transported to its operating position on the dough conveyor, the dough pressing device moves downward, and the edge parts of the dough folded by the folding device except the folding edge are tightly attached to the upper and lower layers of the dough formed after folding, and there is no obvious gap between the upper and lower layers of the dough, and the stuffed food embryo formed by folding is fixed, so as to prevent the stuffed food embryo or the upper layer of the stuffed food embryo from being lifted or deviated when the folding device is reset;

[0007] The dough conveyor continues to convey the stuffed food embryo with the edges tightly attached to the next corresponding operation position below the embryo shaping device. The embryo shaping device acts on the junction between the edge parts of the stuffed food embryo except the folded edge and the filling, and again attaches the upper layer of dough to the lower layer of dough to minimize the gap, while gathering the filling in the dough to the middle position of the folded edge of the stuffed food embryo.

[0008] The dough pressing device and the preform shaping device continuously press and shape the preforms of stuffed food on the dough conveyor.

[0009] Because the folding device is from the bottom of the dough conveyor of the food processing machine, flipped to the upper surface of the dough conveyor to fold the dough that has been injected with fillings, and it needs to flip down and reset after folding, and there is no pressing effect on the upper layer of the dough after folding, and it is easy to lift the dough again when flipping and resetting. The setting of the dough pressing device blocks the stuffing food embryo before the folding device is reset, effectively preventing the stuffing food embryo from deviating from the normal conveying track due to the adhesion of the dough to the machine surface of the folding device or the movement of the stuffing food embryo during resetting. Before the folding device is reset, the stuffing food embryo is fixed in time and the folded dough is processed to reduce the gap between the upper and lower layers of the dough. The embryo shaping device set behind the dough pressing device can also further process the stuffing food embryo, so that the gap between the upper and lower layers of the dough after folding is reduced as much as possible, and at the same time, the distribution of the filling is arranged to make the embryo conveyed to the forming part more beautiful.

[0010] The parts of the dough pressing device and the embryo shaping device that contact the dough are made of elastically deformable materials. The elastic and tough embryo shaping device gently pushes the filling toward the middle of the folded edge of the stuffed food embryo during the downward pressing process, so that the gap between the dough is further reduced, and the scattered fillings can also be gathered, making the shape of the stuffed food embryo more beautiful. Because the elasticity of the material buffers a certain amount of extrusion force, it will not cause excessive extrusion on the edge of the dough. The gap between the upper and lower layers of the dough is only reduced as much as possible without obvious deformation; the internal filling is gently pushed to the middle of the stuffed food embryo by the shaping part of the elastic material, and the dough around the filling is not deformed due to extrusion. The taste of the stuffed food embryo is also guaranteed, so that the finished product can still feel the softness of the dough when it is eaten.

[0011] The position where the embryo shaping device contacts the embryo of the stuffed food is located inside the contact between the dough pressing device and the edge of the dough and closer to the portion containing the fillings. Therefore, the embryo shaping device is smaller and more compact than the dough pressing device, and can act on the portion of the embryo of the stuffed food that is not processed by the dough pressing device and is close to the middle, so as to gather the scattered fillings.

[0012] The dough pressing device and the preform shaping device are fixedly connected, and the distance between the two is equal to the distance between two adjacent operating positions on the dough conveyor. In this way, the dough conveyor can convey the preform of stuffing food just processed by the dough pressing device to the corresponding operating position of the preform shaping device after one step, which is conducive to timely shaping of the preform of stuffing food.

[0013] The dough pressing device and the embryo shaping device obtain power through a cylinder, an electric cylinder or the operator manually. The operator can manually control a row of stuffed food embryos to process multiple times, and adjust in time according to the actual processing effect. Preferably, the cylinder or electric cylinder is used for power supply, which improves the mechanization degree of the device, reduces the labor, and significantly improves the processing efficiency. Preferably, the working frequency of the dough pressing device and the embryo shaping device is consistent with the stepping frequency of the dough conveyor, and the spacing between the dough pressing device and the embryo shaping device is the same as the spacing between each row of operating positions on the dough conveyor. Therefore, the dough conveyor steps once, the product on the operating position is conveyed in one row, the dough pressing device and the embryo shaping device process two adjacent rows of products once respectively, and the stuffed food embryo processed by the dough pressing device is timely shaped into the filling, avoiding the situation where the filling is more dispersed due to the vibration of the dough conveyor.

[0014] A device for pressing and shaping a stuffed food embryo, comprising a folding device, which is a frame structure and is arranged on a dough conveyor, and is used to fold the dough that is still flat on the dough conveyor after the filling is injected along the center line of the dough; a dough pressing device is arranged above the folding device, including a pressing part, the shape of which is the same as the shape of the other edges of the folded dough except the folded edge, and is used to make the upper and lower layers of the folded dough fit as closely as possible and fix the position of the stuffed food embryo when the folding device is reset; a embryo shaping device is installed behind the dough pressing device, including a shaping part, the specifications of which are adapted to the filling specifications of the stuffed food embryo, and is used to gather and shape the filling of the stuffed food embryo after the dough edge has been pressed.

[0015] The folding device of the frame structure only acts on the edges of the dough except the folded edges, and will not squeeze the fillings. The shape of the pressing and shaping device and the part of the folding device that contacts the dough are matched with the shape of the initial dough of stuffed pasta. The user can choose a device of corresponding shape according to the actual processing and use conditions, so that the contact area between the dough and the device can be reduced as much as possible, and the effective contact area can be increased to ensure the taste and enhance the appearance. Because the dough pressing device is used to process the edge of the dough, and the initial dough shaping device is mainly used to gather the fillings, the specifications of the internal structure of the initial dough shaping device are generally smaller than those of the dough pressing device, and the arrangement of the internal structure of the dough pressing device is more compact than that of the initial dough shaping device.

[0016] Preferably, the pressing part and the shaping part respectively include a pressure strip group, the number of the pressure strip groups corresponds to the stuffing food embryo on the dough conveyor, and the pressure strip groups are made of elastically deformable materials. The length and width of each pressure strip group of the pressing part are greater than the pressure strip group of the shaping part, and the spacing between the pressure strip groups of the pressing part is smaller than the pressure strip groups of the shaping part. The pressure strip groups on the dough pressing device and the embryo shaping device are arranged at equal intervals, corresponding to the operating positions on the dough conveyor one by one, so that a whole row on the dough conveyor can be processed at the same time, which improves production efficiency. Compared with a device made entirely of harder materials, the part in contact with the dough is made of soft, elastic and tough materials, so the device will be stronger and more durable, and still have obvious effects on the processing of dough and filling distribution, with low manufacturing difficulty, and the manufacturing cost of the device is controlled. By selecting materials with appropriate flexibility and enabling the operator to control the downward pressure manually or through mechanical power, this series of processing steps can minimize the part of the dough that is severely squeezed and deformed, ensure that the distance between the upper and lower layers of dough is reduced as much as possible, and at the same time, the filling is pushed to the middle of the folded edge of the stuffed food embryo, where it is wrapped more tightly, thereby ensuring the softness of the dough and the freshness of the filling when eaten.

[0017] Preferably, food-grade silicone can be used, and the vertical force applied by the pressing part and the shaping part to the folded dough skin is buffered, so as not to repeatedly press the edge of the dough skin and affect the taste of the final product; especially the pressure strip group of the shaping part, during the pressing process, the pressure strips in the pressure strips make the dough skin subject to downward force, and the side of the pressure strips can be gently deformed to gently push the fillings to the middle, so as to achieve the function of pressing the dough skin and gathering the fillings at the same time, and effectively control the production cost while ensuring the safety of the device. Further, the pressure strip can be a single solid soft silicone strip or a hollow hose, which uses its own material properties and structural characteristics to apply downward force while gently squeezing the dough skin on the left and right sides. It is also possible to use a stacked arrangement of multiple layers of hollow hoses, silicone strips, etc., or a hose with a large cross-sectional area, and insert a support plate inside to increase its strength. Such an arrangement will have better flexibility and flexibility than a single arrangement structure, and will significantly improve the lamination effect of the dough skin and the shaping effect of pushing the fillings.

[0018] Preferably, the pressing part and the shaping part are detachably fixedly connected to the dough pressing device and the preform shaping device. The pressing part and the shaping part can be fixed to the lower part of the dough pressing device and the preform shaping device by a plurality of bolts, so that they can be disassembled at any time to replace new pressure strips or pressure strips of different specifications and shapes; or devices such as velcro or slides can be provided to fix the pressing part and the shaping part, which can reduce the weight of the whole device to a certain extent and reduce the operating burden.

[0019] Preferably, the dough pressing device and the preform shaping device also include a connecting part, which is arranged above the dough pressing device and the preform shaping device and connected to the dough conveyor, and a power mechanism is arranged on the connecting part, which is used to drive the dough pressing device and the preform shaping device to move synchronously. The arrangement of the connecting plate increases the installation area of ​​the dough pressing device and the preform shaping device, and the arrangement of the power mechanism on the connecting plate also achieves the effect of synchronous movement of the two parts, improves the mechanization degree of the device, and reduces the workload of the operator; the positions of the dough pressing device and the preform shaping device as a whole are relatively fixed, and the folded stuffed food preform can be promptly allowed to allow the preform shaping device to participate in the arrangement of the filling and the further fitting of the dough edge after being processed by the dough pressing device, so that the space for the machine layout is more compact and avoids interference with other components.

[0020] Compared with the prior art, the essential features of the present invention are:

[0021] In terms of method, by pressing the dough, timely positioning the folded stuffed food, further fitting the edge of the folded stuffed food embryo and gathering the stuffing, the taste and appearance of the stuffed food embryo are significantly improved, the number of qualified products and high-quality products is greatly increased, and the production efficiency is improved;

[0022] Structurally: (1) A pressing and shaping device made of a material with strong flexibility and elasticity is used, and the specifications can be easily changed according to the actual shape of the product being processed. This can better control the degree of processing of the dough and fillings, and will not change the thickness of the dough too much before the final forming, thus ensuring the softness of the dough.

[0023] (2) Adding a device that can shape the filling makes the shape of the stuffed food embryo fuller and rounder, and prevents excessive loss of water in the filling, thereby ensuring that the filling is fresh and delicious when eaten. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Example 1

[0033] As shown in the accompanying drawings, a method for pressing and shaping a stuffed food embryo is used for pressing and shaping a stuffed food made of a rectangular dough. The device for implementing the pressing and shaping method includes a movable bracket 9 fixed at one end to a dough conveyor 11, a pressing part 1 and a shaping part 2.

[0034] The other end of the movable bracket 9 is connected to the layering bracket 5 of the pressing part 1 and the shaping part 2 respectively through the power mechanism, the first mounting plate 3 and the second mounting plate 4 located in the middle, so that the layering bracket 5 with the layering group can move up and down to press the edge of the dough of the stuffed food embryo located on the lower dough conveyor 11 except the folded edge.

[0035] The pressing part 1 is arranged above the folding device 10 to fix the dough in time after kneading. On the one hand, the upper and lower layers of the dough can be tightly fitted together after folding to prevent leakage of fillings. On the other hand, under the pressure of the pressing part 1, the folding device 10 will not lift up the upper layer of dough when it is reset and flipped, thereby ensuring the quality of the initial forming of the stuffed food each time.

[0036] The shaping part 2 is arranged along the conveying direction of the stuffed food embryos on the dough conveyor 11, gathers the stuffing of the compacted stuffed food embryos, pushes the stuffing originally spread on the dough to the middle of the folded edge, and further processes the dough edge near the stuffing, so that the upper and lower doughs are as close as possible. The spacing between the two layering strip supports 5 is the same as the spacing between each row of stuffed food embryos on the dough conveyor 11, so as to realize the simultaneous pressing and shaping of two adjacent rows of stuffed food embryos.

[0037] The strips in the strip group are all made of soft, tough and elastic materials, and are fixed to the strip bracket 5 by bolts, wherein the strip group of the pressing part 1 includes a first strip 6, a second strip 7 and a third strip 8, and the strip group of the shaping part 2 includes a fourth strip 12, a fifth strip 13 and a sixth strip 14; the first strip 6, the second strip 7 and the fourth strip 12, the fifth strip 13 located on both sides are respectively perpendicular to the third strip 8 and the sixth strip 14 in the middle, and the length of the first strip 6, the second strip 7 and the third strip 8 is greater than that of the fourth strip 12, the fifth strip 13 and the sixth strip 14.

[0038] The user selects a layering support 5 of the same width as the dough conveyor 11 and a layering group adapted to the number and shape of edges of the dough conveyor 11 according to the specifications of the stuffed food preforms to be processed. The movable support 9 with a power mechanism installed above the layering support 5 is connected to the frame of the dough conveyor 11 at the top and to the first mounting plate 3 and the second mounting plate 4 on the layering support 5 at the bottom. When the power mechanism is working, it drives the pressing part 1, the shaping part 2 and the dough conveyor 11 to move synchronously at the same frequency.

[0039] After the stuffing is injected into the stuffing food dough on the dough conveyor 11, the folding device 10 turns over to fold the dough. At this time, the power mechanism of the movable bracket 9 works to drive the layering bracket 5 connected thereto to move downward as a whole, so that the layering strip on the pressing part 1 contacts the edge of the stuffing food embryo; a slight squeezing force is formed on the upper surface of the dough conveyor 11 which is relatively fixed in the vertical displacement, so that the edge gap of the stuffing food embryo is reduced, and the first row of stuffing food embryos is pressed; after the pressing part 1 fixes the stuffing food, the filling strip on the pressing part 1 is fixed. After the initial embryo is formed, the folding device 10 is turned over and reset; the dough conveyor 11 and the power mechanism continue to step simultaneously, and the row of stuffed food initial embryos is conveyed to the bottom of the shaping part 2. The shaping part 2 fits the edge of the initial embryo of this row again, and uses the small size of the layering structure and the flexibility of the material itself to squeeze the filling to the middle position of the folded edge of the initial embryo of the stuffed food during the downward pressing process, and arranges the distribution of the filling so that the filling is fully gathered. At the same time, the initial embryo of a new row of stuffed food is conveyed to the pressing part 1 for processing.

[0040] In this way, after the kneaded stuffed food embryo is processed by the pressing part 1 and the shaping part 2 with two rows of tough soft pressure strips, the action of the folding device 10 will not affect the position and wrapping effect of the stuffed food embryo too much. The filling in the embryo is more concentrated, and the shape is complete and full. It is transported to the subsequent processing steps, effectively ensuring the quality and taste of the finished product.

[0041] Example 2

[0042] When processing stuffed food made of circular dough, a plurality of semicircular pressure strips are respectively arranged under the pressing part 1 and the shaping part 2, and the pressure strip radius of the pressing part 1 is larger than the pressure strip radius of the shaping part 2. After the folding device 10 folds the circular dough into a semicircle from the center line, the pressing part 1 presses down on the edge of the dough to fix the folded dough. When the folding device 10 is reset, the dough will not move or stick to the surface of the folding device 10 and be lifted up, and a stuffed food embryo is initially formed; the dough conveyor 11 continues to step, so that the stuffed food embryo is conveyed to the processing position corresponding to the shaping part 2, and the shaping part 2 moves downward to act on the stuffed food embryo. The filling originally flat and relatively dispersed inside is squeezed by the shaping part 2 and gathered to the middle of the folded edge of the stuffed food embryo, so that the filling forms a full and solid shape. At the same time, the edge of the stuffed food embryo is squeezed again, and the gap between the upper and lower layers of dough is further reduced, reducing the possibility of filling leakage.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
