Description

Technical Field

[0001] The present invention belongs to the technical field of the production and application of hanging noodles, and particularly relates to a rolling device for the production of hanging noodles. Background Art

[0002] The rolling process is very common in the processing industry of flour products. The dough is passed through a pair of relatively rotating cylindrical rolling rollers. In the gap between the two rollers, the dough is compressed to complete the process of extension and thinning. Usually, in the rolling process, multiple stages of rolling rollers are required to gradually roll and thin the dough into a continuous sheet. The function of the rolling process is to press the granular dough into a sheet, gather the dispersed starch granules and gluten together to form a tight network structure, make the gluten evenly distributed in the sheet and wrap the starch granules, so as to well reflect the plasticity, viscoelasticity and extensibility of the dough. The rolling determines the quality of the final product.

[0003] The traditional rolling only has an extrusion effect on the sheet, and only unidirectionally rolls the sheet, playing the role of pressing the sheet from thick to thin. Since the sheet is relatively thick and only unidirectionally rolled, it is not conducive to the distribution of the gluten network in other directions, resulting in uneven distribution of the gluten network. After the noodles are cooked, the surface compressive resistance of the noodles is low, resulting in insufficient elasticity.

[0004] To solve the above problems, various technical solutions have been proposed. For example, a method for rolling a sheet, a sheet rolling unit and its sheet and flour food disclosed by the State Intellectual Property Office {Application No.: 200510012259.9}, which uses a rolling roller to perform the first rolling on a long strip-shaped sheet, so that the sheet after the first rolling generates an extension along the length direction of the long strip; the sheet after the first rolling is reciprocally folded at a preset angle to form a stacked long strip-shaped folded sheet; another rolling roller is used to perform the second rolling on the long strip-shaped folded sheet, so that the sheet after the second rolling generates an extension along the length direction of the long strip-shaped folded sheet.

[0005] Although this method effectively realizes the grid distribution of gluten, the grid of the gluten is broken and discontinuous, which leads to the easy breakage of the formed hanging noodles.

[0006] Or, the noodle rolling machine disclosed by the State Intellectual Property Office {Patent No.: CN201710171284.4} includes a frame, a dough feeding mechanism and a rolling mechanism. The rolling mechanism includes a lifting plate, a lining plate and a rolling plate which are sequentially arranged from bottom to top. A number of power rollers are arranged in a rectangular array on the lifting plate. Each power roller includes a baffle plate and a cylindrical rotating roller. The baffle plate is fixed on the lifting plate. Through holes matching with the power rollers are formed on the lining plate. The lining plate is stacked on the lifting plate. The power rollers are slidably connected in the through holes on the lining plate. A rolling roller and a noodle pushing roller are arranged on the rolling plate. The noodle pushing roller is parallel to the rolling roller. The dough feeding mechanism includes a horizontal dough feeding cylinder and a vertical dough feeding cylinder. A horizontal dough feeding hole is formed on the horizontal dough feeding cylinder. A vertical dough feeding hole is formed on the vertical dough feeding cylinder. The horizontal dough feeding cylinder and the vertical dough feeding cylinder are arranged on two adjacent sides of the lifting plate.

[0007] Although the mesh of the obtained dough sheet is complete in the above device, it needs to cut the dough sheet before rolling, resulting in its inability to produce in large scale and batch. Summary of the Invention

Detailed implementation manners

[0028] In order to more clearly understand the above - mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0029] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0030] Embodiment 1, as Figures 1 to 5 shown, the purpose of this embodiment is to improve the gluten of noodles while ensuring batch production, and in addition, to ensure the compactness of the structure to avoid taking up too much space. For this purpose, in order to achieve the above - mentioned purpose, the calendering device for producing dried noodles provided in this embodiment includes a frame 1 and a calendering roller group 2 arranged on the frame 1. It should be noted that there are multiple calendering mechanisms in the existing production line for batch - producing dried noodles. The dough sheets are pressed to the required thickness through the calendering mechanisms arranged at intervals. In this embodiment, the provided calendering device is only the most front - end calendering mechanism in the entire calendering system, and the subsequent calendering mechanisms used can be common existing calendering mechanisms.

[0031] The frame 1 also adopts the structure of the existing common left and right wallboards. The rolling device is composed of two rollers that rotate in opposite directions up and down. While squeezing the dough sheet, it also completes the backward conveying of the dough sheet. In this embodiment, it should be noted that in this embodiment, the front and back are not described according to the actual spatial position where the structure is located, but are described with the moving direction of the dough sheet as the rear.

[0032] Considering that the network formation of gluten requires the gluten to form a criss-cross distribution while ensuring continuity, two dough sheets are needed. If two rolling mechanisms are used, there will be problems such as large floor area and waste of resources. Therefore, in this embodiment, a splitting knife 13 is also provided on the frame 1. The blade of the splitting knife 13 is arranged relative to the dough sheet. The splitting knife 13 is arranged in the middle of the frame 1 and behind the rolling roller group 2. The rolling roller group 2 is arranged close to the splitting knife 13. The purpose of this setting is to ensure that the dough sheet has sufficient power.

[0033] In this way, the splitting knife 13 splits the dough sheet into two sheets arranged left and right. After splitting, the dough sheets need to be overlapped alternately to achieve the network formation of gluten. Therefore, in this embodiment, a left channel 11 and a right channel 12 are also provided behind the splitting knife 13. The left channel 11 and the right channel 12 are arranged at an angle. In this embodiment, in order to avoid the dough sheet breaking due to too large an angle, in this embodiment, the angle between the left channel 11 and the right channel 12 is 60°.

[0034] In order to make the structure of the whole device more compact, in this embodiment, guide rollers 3 are arranged in both the left channel 11 and the right channel 12. The guide rollers 3 are rotatably arranged on the frame 1. In this embodiment, the guide rollers 3 are unpowered rollers, which are used to change the moving direction of the split dough sheet and make it move in the opposite direction. This can not only make the structure more compact, but also help the split dough sheets to cross and overlap. That is, the moving directions of the split dough sheets by the guide rollers 3 are arranged at a crossing angle.

[0035] Considering that only the cross-overlapping of the dough sheets can form a network of gluten, but the effect is not good. Therefore, in this embodiment, a indentation roller group 4 for pressing long strip marks on the dough sheet is also provided behind the guide roller 3. In this way, the long strip marks form another kind of artificial gluten, and then, after crossing each other, they further form a network setting.

[0036] The cross-overlapped dough sheets need to be fused. Therefore, a fusing roller group 5 is arranged behind the indentation roller group 4. The fusing roller group 5 is arranged at the intersection of the two dough sheets. In this way, the two dough sheets are pressed together into one sheet by using the fusing roller group 5.

[0037] Considering that the output direction of the dough sheet after lamination is opposite to that of the subsequent rolling mechanism, an auxiliary guiding roller 6 is provided behind the fusion rolling roller group 5. The auxiliary guiding roller 6 is also a power-free roller, which, like the guiding roller 3, turns the dough sheet upward. In this way, the moving direction of the dough sheet is the same as the direction when the dough sheet just enters, so as to connect with the subsequent rolling mechanism.

[0038] Considering that the shape and size of the dough sheet extruded by the fusion rolling roller group 5 may not meet the requirements of the subsequent rolling mechanism, an output rolling roller group 7 is provided behind the auxiliary guiding roller 6. The output rolling roller group 7 is arranged above the fusion rolling roller group 5. In this way, the output rolling roller group 7 further rolls the dough sheet to make the thickness of the output dough sheet consistent with that of the dough sheet when it enters, so as to facilitate the connection with the subsequent rolling mechanism. At the same time, the output rolling roller group 7 also gives the dough sheet further power to ensure the continuity of production.

[0039] In order to form long strip marks, in this embodiment, the indentation roller group 4 includes an upper indentation roller 41 and a lower indentation roller 42. Among them, both the upper indentation roller 41 and the lower indentation roller 42 include a roller body 43 and indentation rings 44 arranged at intervals on the roller body 43. In this way, the indentation rings 44 leave long strip marks on the dough sheet.

[0040] In order to avoid the dough sheet breaking due to multiple long strip marks, in this embodiment, the indentation rings 44 of the upper indentation roller 41 and the lower indentation roller 42 are arranged in a staggered manner, and the upper indentation roller 41 and the lower indentation roller 42 are arranged at intervals. In this way, the valleys and peaks on the upper surface of the dough sheet correspond to the valleys and bottoms on the lower surface, making the dough sheet wavy to avoid breakage.

[0041] In order to further reduce the height of the whole device, in this embodiment, the fusion rolling roller group 5 includes an upper fusion roller 51 and a lower fusion roller 52, and the output rolling roller group 7 includes an upper output roller 71 and a lower output roller 72. Among them, the upper fusion roller 51 and the lower output roller 72 are arranged in coincidence, that is, the upper fusion roller 51 and the lower output roller 72 are the same roller. And because the output direction of the fusion rolling roller group 5 is opposite to that of the output rolling roller group 7, gears 8 are sleeved on the rotating shafts of the upper fusion roller 51, the lower fusion roller 52 and the upper output roller 71, and adjacent gears 8 are meshed with each other. In this way, only by driving one gear 8 to rotate, the simultaneous movement of the fusion rolling roller group 5 and the output rolling roller group 7 can be realized. While achieving structural compactness, the use cost is reduced.

[0042] In order to further reduce the use cost, the rolling roller group 2 includes an upper rolling roller 21 and a lower rolling roller 22. Among them, the upper rolling roller 21 and the lower fusion roller 52 are connected by a synchronous belt 9 for transmission. In this way, driven by one motor, the simultaneous movement of the rolling roller group 2, the fusion rolling roller group 5 and the output rolling roller group 7 can be realized.

[0043] To prevent the lower indentation roller 42 from contacting the lower dough sheet, the diameter of the guiding roller 3 is at least more than twice the diameter of the roller body 43. In this way, there is a gap between the lower indentation roller 42 and the lower dough sheet to prevent contact.

[0044] Considering that the horizontal rolling effect is the best, for this reason, the diameter of the auxiliary guiding roller 6 is the same as the diameter of the lower output roller 72. In this way, it is ensured that when the dough sheets are on the same layer, the height is the same.

[0045] To further form artificial gluten, in this embodiment, auxiliary pressing rings 45 are also provided between the pressing rings 44, and the height of the auxiliary pressing rings 45 is set lower than the height of the pressing rings 44. Since both the pressing rings 44 and the auxiliary pressing rings 45 are annular structures, and the height of the auxiliary pressing rings 45 is lower than the height of the pressing rings 44, in this way, a space in the shape of a small included angle is formed between the pressing rings 44 and the auxiliary pressing rings 45. In this way, during the pressing process, there is a groove at the top of the formed valley peak, and one valley peak forms a structure with two ribs, thereby improving the densification of the gluten network.

[0046] To further form artificial ribs and improve the elasticity of the noodles, in this embodiment, polygonal protruding ribs 46 are provided on the auxiliary pressing rings 45. The polygonal protruding ribs 46 are formed by a combination of multiple protruding ribs to form a polygon. In this way, the polygonal protruding ribs will also increase indentations in the middle of the formed valley peaks to form artificial ribs, and the polygonal protruding ribs 46 are annularly distributed on the auxiliary pressing rings 45.

[0047] Considering that the left and right dough sheets need to overlap, to facilitate the formation of sleeve ribs by the indentations formed by the polygonal protruding ribs 46, in this embodiment, the polygonal protruding ribs 46 are arranged in a regular hexagon, and the regular hexagon indentation set formed by the indentation roller group 4 in the left channel 11 is arranged outside the regular hexagon indentation set formed by the indentation roller group 4 in the right channel 12. In this way, sleeve ribs are formed. It should be noted that the spacing between the polygonal protruding ribs 46 in the right channel 12 should be greater than the spacing in the left channel 11 to ensure sleeving. Of course, the distance from the center point to the center point is the same. During the sleeving process, manual traction is required. Manual traction of the dough sheet is required in the early stage of rolling.

[0048] The above are only the preferred embodiments of the present invention, and are not limitations on the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
