[0002] In food manufacturing and processing, the filling is extruded and shaped by the filling dispensing structure to obtain the skin filling, which is then wrapped on the surface of the dough. After expansion and baking, the skin filling forms cracks of appropriate size on the surface of the dough. If the filling has a large specific gravity, the length of the skin filling will be shorter when the filling weight is consistent, which will lead to the problem of "whitening" when the skin filling wraps the dough. However, increasing the weight of the filling will lead to higher costs. Utility Model Content

[0033] The technical solution provided in this application will be further described below in conjunction with embodiments and drawings.

[0034] In the process of food processing, especially in the process of bread and pastry processing, it is often necessary to wrap a layer of skin filling on the outer layer of bread, such as Danish pineapple milk soufflé and pineapple croissant. During the proofing and baking process of the bread, the dough ferments and expands, and the pineapple skin filling on the surface cracks. After being evenly brushed with egg yolk liquid and put into the oven for baking, the pineapple skin filling is golden on the surface and forms cracks of appropriate size, which is not only beautiful but also further enriches the taste. In the current production process, the dough detection sensor of the filling injection equipment senses the dough, and the pneumatic system drives the piston valve of the filling structure to squeeze the pineapple skin filling out to the dough surface through the blocking valve and the filling outlet. The shape of the filling outlet is as follows: Figure 1 The shape of the filling outlet will affect the weight of the pineapple skin filling and has an important impact on the appearance of products such as Danish pineapple milk soufflé. It is understandable that the use of Figure 1 The filling structure with the filling outlet shape shown can obtain a filling with a uniform overall thickness. When the filling weight is constant, the greater the filling weight, the smaller the volume of the filling squeezed out of the filling outlet. Generally, the width of the filling is relatively fixed, that is, the volume of the filling means the length of the filling becomes shorter, and then the filling will have a "white" problem when wrapping the dough, affecting the appearance of the product, but increasing the weight of the filling will lead to higher costs.

[0035] Based on the above analysis, if Figure 2As shown, an embodiment of the present application provides a filling injection structure 1, which has a through groove, and the through groove is used to pass the filling and extrude the filling to shape it. The through groove includes a filling inlet 12 and a filling outlet 11. The filling enters the through groove through the filling inlet 12, and the skin filling after extrusion and shaping is extruded through the filling outlet 11; wherein, the filling outlet 11 is a long strip structure, and along the length direction, the long strip structure is wide in the middle and narrow at both ends in the thickness direction. It can be understood that the filling is extruded through the filling outlet 11 that is wide in the middle and narrow at both ends, and a skin filling that is thick in the middle and thin on both sides can be obtained. Compared with skin fillings of equal thickness (here, the thickness is the same as the middle part), under the same weight and specific gravity of the filling, the filling that is thick in the middle and thin on both sides can obtain a longer skin filling, thereby achieving full wrapping of the dough by the skin filling. Although the thickness of the skin filling on both sides becomes thinner, the overall impact on the appearance and taste of the bread is relatively small. This is because during the baking process of bread, the middle part is heated more evenly and expands faster than the two side parts, while the edge part may be heated faster due to direct contact with the baking pan or the oven wall, but the expansion amplitude is relatively small. Therefore, during the baking process, the thicker part in the middle of the skin filling with thin sides expands more significantly, while the thinner parts on both sides expand less significantly, and then after the bread is baked, the skin filling on the outer surface is more uniform and beautiful as a whole. In addition, in combination with production practice, taking the production of pineapple buns as an example, the skin filling squeezed out of the filling spouting port 11 is usually manually wrapped by the operator to the dough, and the operator puts his hand on the thicker part in the middle of the skin filling, and then pushes the skin filling away to wrap the dough, and the thicker skin filling in the middle avoids the skin filling from breaking during the wrapping process, while the thinner parts on both sides of the skin filling are convenient for the operator to push it away to fully wrap the dough.

[0036] Furthermore, in the thickness direction, the long strip structure gradually and smoothly narrows from the middle to the two ends along the length direction. There are many types of long strip structures that are wide in the middle and narrow at both ends, such as Figure 3 and Figure 4 As shown, they are all long strip structures that are wide in the middle and narrow at both ends. Figure 3 and Figure 4 The medium-long strip structure does not gradually narrow from the middle to the ends, but suddenly narrows. Figure 3 , Figure 4 Although the filling injection structure 1 with the filling outlet 11 of the long strip structure can obtain a skin filling that is thick in the middle and thin at both ends, the skin filling has a sudden change in thickness locally, and is prone to hardening and cracking when heated and expanded. As a preferred embodiment, the long strip structure is gradually narrowed from the middle to the two ends, such as Figure 5 As shown, when baking bread, the crust and filling obtained by this design can expand more evenly.

[0037] Furthermore, the middle width of the long strip structure is a, the width of the two sides of the long strip structure is b, and the length of the long strip structure is c, then a:b:c=(5-7):(4-6):(15-20), such as Figure 5As shown. The ratio of each parameter of the long strip structure of the filling outlet 11 can reflect the difference in thickness between the middle and both sides of the obtained skin filling to a certain extent. If the middle is too thick, it will lead to waste of fillings, and the skin filling is not easy to push open and wrap the dough. If the middle is too thin, the skin filling may break when pushing the skin filling, or the skin filling in the middle is too thin after wrapping the dough, and then the skin filling will break greatly after heat expansion to produce "white exposure".

[0038] Along the thickness direction of the filling outlet 11, the through groove has a first surface 111 and a second surface 112 arranged opposite to each other. As an embodiment, the first surface and the second surface are both concave arc surfaces. In this embodiment, Figure 5 As shown, two opposite arc-shaped filling outlets 11 are formed at one end of the filling injection structure 1 having the filling outlet 11, and the arc depths of the two arcs can be equal or unequal, and a thicker skin filling in the middle and thinner skin filling on both sides can be obtained. It can be understood that the arc surface is a gentle curved surface, and the filling injection structure 1 with a through groove provided with an arc surface can make the thickness of the obtained skin filling transition from thick in the middle to thin on both sides more evenly, which is beneficial to the control of the appearance of the skin filling.

[0039] As another embodiment, the first surface 111 is a concave arc surface, and the second surface 112 is a convex arc surface. Figure 6 As shown, at one end of the filling injection structure 1 having the filling outlet 11, two arcs with different arc depths are formed to enclose the filling outlet 11, and the arc depth of the concave arc surface is greater than the arc depth of the convex arc surface, thereby obtaining a thicker skin filling in the middle and thinner skin filling on both sides. It is understandable that the first surface 111 can also be a convex arc surface and the second surface 112 can be a concave arc surface, and this setting can also achieve the effect described in the present application.

[0040] As another embodiment, the first surface 111 is a concave arc surface, and the second surface 112 is a flat surface. Figure 7 As shown, using the filling-dispensing structure including this arrangement, a thicker middle and thinner skin filling can also be obtained. It is understandable that the first surface 111 can also be a plane, and the second surface 112 can be a concave arc surface, and this arrangement can also achieve the effect described in the present application.

[0041] Further, the filling inlet 12 is a long strip structure, and the shape and size of the long strip structure of the filling inlet 12 and the filling outlet 11 are the same. It can be understood that in the filling device, the filling enters the filling structure 1 through the filling inlet 12, and the shape and size of the filling inlet 12 can be designed according to the type and fluidity of the filling. The filling outlet 11 is used to extrude the extruded skin filling, and the shape and size of the filling outlet 11 can also be designed according to actual conditions to ensure that the food can be discharged from the equipment completely and regularly. In other words, the shape and size of the filling outlet 11 can be the same as or different from the filling inlet 12. In the embodiment of the present application, the filling inlet 12 and the filling outlet 11 correspond to the two ends of the through groove respectively. When the through groove is designed, it is easy to obtain the filling inlet 12 and the filling outlet 11 of the same shape, and the filling can be shaped after entering the through groove through the filling inlet 12, and the overall shape of the skin filling when extruded from the filling outlet 11 is relatively uniform and stable.

[0042] Further, the filling injection structure 1 has a first guide portion 13 protruding from the plane where the filling outlet 11 is located; and / or, the filling injection structure 1 has a second guide portion 14 protruding from the plane where the filling inlet 12 is located. Taking the first guide portion 13 protruding from the plane where the filling outlet 11 is located as an example, please refer to Figure 2 The first guide portion 13 can make the filling move along a predetermined path and direction when it is squeezed out of the filling outlet 11, which is beneficial to assembly line production. The height of the first guide portion 13 protruding from the plane where the filling outlet 11 is located can be set according to specific conditions, such as the overall length of the filling, the humidity of the filling, etc.

[0043] Furthermore, a flow guide structure 15 is formed at the filling inlet 12, and along the filling inlet direction, the cross-sectional area of ​​the flow guide structure 15 in the direction perpendicular to the filling inlet gradually decreases. The flow guide structure 15 at the filling inlet 12 can ensure that the filling flows into the interior of the device according to a predetermined path and direction, and the specific shape and angle can guide the filling to smoothly enter the filling inlet 12 to avoid blockage or leakage. The cross-sectional area of ​​the flow guide structure 15 in the direction perpendicular to the filling inlet gradually decreases, that is, compared with the end where the flow guide structure 15 and the filling inlet 12 are connected, the end of the flow guide structure 15 for receiving the filling has a larger opening. On the one hand, this design can effectively prevent the filling from splashing to the outside of the equipment and keep the production equipment clean and hygienic. On the other hand, this design allows the pressure of the filling away from one end of the filling inlet 12 to be transmitted to one end of the filling inlet 12, so that the filling flows more smoothly inside the filling injection structure 1, thereby improving the production efficiency and operation stability of the equipment.

[0044] As an optional implementation, Figure 8As shown, the cross-section of the flow-guiding structure 15 parallel to the filling feeding direction is an isosceles trapezoid. The isosceles trapezoidal design allows the filling inlet 12 to have a certain opening width, which can accommodate larger or more viscous fillings, thereby reducing production interruptions caused by filling blockage. In addition, the isosceles trapezoidal design also helps to reduce the turbulence and vortex generated by the filling during the flow process, further preventing the occurrence of blockage. The flow-guiding structure 15 can also be a non-isosceles trapezoid. By adjusting the length of the upper and lower bases of the trapezoid, the flow rate and flow of the filling can be further controlled to avoid blockage of the filling inlet 12 and ensure the normal operation of the equipment.

[0045] Furthermore, the material of the filling structure 1 includes one or more of stainless steel, polytetrafluoroethylene, and silicone. The commonly used material of the filling structure 1 depends on the specific application requirements, working environment, and cost considerations. Stainless steel is one of the most commonly used materials in the food industry because it has good corrosion resistance, good mechanical properties, and is easy to clean and disinfect. Materials such as polytetrafluoroethylene and silicone have excellent wear resistance, high temperature resistance, and chemical stability, and are also widely used in food production without producing substances that are harmful to the human body.

[0046] In a second aspect, the present application provides a filling injection device, which includes the filling injection structure 1 of the first aspect.
