Description

Technical Field

[0001] This utility model relates to the field of rice noodle pre-drying technology, and in particular to a rice noodle separation device for a pre-drying box. Background Technology

[0002] Anren hot rice noodles are a local specialty, similar to Shahe rice noodles, but with significant differences, requiring a higher level of craftsmanship. The rice noodles have two sides after coming out of the steamer; the side covered by the steaming cloth is called the reverse side, which is not smooth and is very sticky.

[0003] The pre-drying chamber is heated and air is supplied. The powder sheets move back and forth in the pre-drying chamber, thus removing some of the moisture from the powder sheets. When the reverse side of the powder sheet is attached to the mesh belt and moves forward to the end, because the reverse side of the powder sheet is very sticky, the powder sheet often sticks to this layer of mesh belt and will not fall to the next layer of mesh belt automatically. Utility Model Content

[0004] This utility model provides a powder and skin separation device for a pre-drying box, which aims to solve at least one of the above-mentioned technical problems.

[0005] This utility model provides the following technical solution: A rice noodle separation device for a pre-drying box includes multiple conveyor belts inside the pre-drying box. The topmost conveyor belt receives rice noodles output from the steaming box, and several layers of folding conveyor belts are arranged vertically below it. Multiple rice noodle separation rollers are installed inside the pre-drying box. The rice noodle separation rollers are located below the ends of the conveyor belts, and there is a gap between the rice noodle separation rollers and the corresponding ends of the conveyor belts. The rice noodle separation rollers and the corresponding conveyor belts rotate synchronously and at matching speeds.

[0006] Furthermore, the rice noodle sheet has a front and a back side, with a rice noodle sheet separation roller installed only on the back side below the outlet of the conveyor belt.

[0007] Furthermore, the rice noodle separating roller is synchronously linked with the drive roller at the end of the corresponding mesh belt.

[0008] Furthermore, the diameter of the rice noodle separating roller is half the distance between two adjacent mesh belts.

[0009] Furthermore, the surface of the rice noodle separating roller is provided with an anti-sticking layer.

[0010] Furthermore, the surface of the rice noodle separating roller is uneven to reduce the contact area between the separating roller and the rice noodle.

[0011] Furthermore, since the rice noodles output from the steamer are very wet, the surface of the first rice noodle separating roller is covered with multiple crossbars and a low-stickiness material. The rice noodle separating roller at the end of the top mesh belt includes a main shaft with mounting plates at both ends. Multiple crossbars are fixed between the mounting plates and are arranged in a ring coaxial with the main shaft. An anti-stick layer is provided on the crossbars.

[0012] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0013] After being discharged from the steaming box, the rice noodle sheets enter the top layer of the pre-drying box via a conveyor belt. As the sheets are conveyed to the discharge end of the pre-drying box, they droop due to their own weight and make slight contact with the surface of the separating roller. This process effectively prevents sticking by utilizing the uneven and low-stick properties of the rice noodle sheets.

[0014] The anti-stick layer effectively prevents the powder from tearing or deforming due to adsorption during the separation process, ensuring its complete detachment.

[0015] The uneven structure can also form tiny support points as the powder passes through, further reducing the risk of sticking and improving separation efficiency.

[0016] The mounting plate and crossbar on the main shaft rotate accordingly. During rotation, the crossbar applies a gentle pushing force to the powder sheets that have detached from the conveyor belt, guiding them smoothly into the lower conveyor belt. The anti-stick layer effectively prevents the powder sheets from sticking or wrinkling during the transfer process.

[0017] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more obvious and understandable, specific embodiments of this utility model are given below.

[0025] To better understand the purpose, function, and specific design of this utility model, the following detailed description is provided in conjunction with the accompanying drawings.

[0026] like Figures 1-5 As shown, this application provides a separation device for a pre-drying box. The pre-drying box 1 is equipped with multiple conveyor belts 2. The topmost conveyor belt 2 is used to receive the rice noodles output from the steaming box. Below it, several layers of folding conveyor belts 2 are arranged vertically. Multiple rice noodle separation rollers 4 are installed at the feed end and the discharge end of the pre-drying box 1. The rice noodle separation rollers 4 are located below the ends of the conveyor belts 2. The rice noodle separation rollers 4 are within the coverage area of ​​the conveyor belts 2 and have a gap with the ends of the corresponding conveyor belts 2. The rice noodle separation rollers 4 rotate synchronously with the corresponding conveyor belts 2 and their speeds are matched.

[0027] At the start of production, the first rice noodle sheet needs to be manually guided through the rice noodle sheet separating roller 4. After that, it can run automatically and continuously. In the self-operating state, the rice noodle sheet is output from the steaming box and enters the top mesh belt 2 of the pre-drying box 1. When it is transported to the discharge end of the pre-drying box 1 by the top mesh belt 2, the rice noodle sheet hangs down due to its own weight as it approaches the discharge end. It makes slight contact with the surface of the separating roller. Utilizing the uneven and low-sticky material characteristics, it effectively avoids sticking and smoothly separates and falls into the lower mesh belt 2 facing the steaming box. When it moves to the feed end of the pre-drying box 1, that is, the end of the mesh belt 2 facing the steaming box, the rice noodle sheet hangs down naturally again. Guided by the next set of separating rollers, it is smoothly transferred to the next layer of return mesh belt 2. It is transferred down level by level to achieve multi-layer continuous drying. Throughout the process, the separating roller and the corresponding mesh belt 2 operate synchronously to ensure that the rice noodle sheet can be accurately separated from the previous mesh belt 2 when transferring to each layer.

[0028] For example, the mesh belt 2 includes drive rollers 3 and tension rollers at both ends, and the mesh belt 2 body sleeved on them. The drive rollers 3 are driven to rotate by a motor, thereby pulling the mesh belt 2 to circulate. The mesh belt 2 is provided with fine mesh holes to facilitate moisture evaporation and prevent the rice noodles from sticking together.

[0029] For example, the zigzag conveyor belt 2 consists of multiple parallel conveyor belts 2, with the end of the upper conveyor belt 2 corresponding to the beginning of the lower conveyor belt 2. This allows the powder sheet to fall naturally under gravity to the lower conveyor belt 2 and continue to be conveyed in the opposite direction, forming a continuous up-and-down zigzag conveying path, effectively extending the drying time of the powder sheet in the pre-drying box 1. In addition, in order to ensure that the powder sheet can smoothly detach from the upper conveyor belt 2 and accurately fall into the lower conveyor belt 2, the end of the upper conveyor belt 2 is shorter than the beginning of the lower conveyor belt 2. That is, in the vertical direction, there is a material drop gap between the end of the upper conveyor belt 2 and the beginning of the lower conveyor belt 2 in the conveying direction.

[0030] For example, the rice noodle separation roller 4 is a cylindrical roller, and both ends of the rice noodle separation roller 4 are rotatably connected to the frame through bearing seats. The rice noodle separation roller is arranged parallel to the drive roller 3 of the corresponding mesh belt 2.

[0031] Preferably, the rice noodle sheet has a front and a back side, and the rice noodle sheet separating roller 4 is installed only on the back side of the rice noodle sheet below the outlet of the mesh belt. The rice noodle sheet separating roller 4 is located slightly behind the end of the mesh belt.

[0032] In some embodiments, the rice noodle separation roller 4 is synchronously linked with the drive roller 3 at the end of the corresponding mesh belt 2.

[0033] For example, in this embodiment, synchronous linkage is achieved by installing a sprocket 6 at the end of the shaft of the drive roller 3 and a matching sprocket 6 on the shaft of the rice noodle separation roller 4. The two are connected by a chain 5 to ensure that the separation roller and the drive roller 3 rotate synchronously, thereby avoiding rice noodle stretching or squeezing due to differences in rotation speed.

[0034] In some embodiments, the diameter of the rice noodle separating roller 4 is half the distance between two adjacent mesh belts 2.

[0035] The aforementioned rice noodle separating roller 4 has a gap with the upper mesh belt 2 so that the rice noodle separating roller 4 will not interfere with the operation of the upper mesh belt 2. The lower side of the rice noodle sorting roller has a gap with the upper surface of the lower mesh belt 2. This gap is slightly less than 1 / 2 of the distance between two adjacent mesh belts 2 (the gap between the rice noodle separating roller 4 and the lower surface of the upper mesh belt 2 needs to be subtracted). This size design allows the rice noodles to pass smoothly through the gap between the lower side of the rice noodle separating roller 4 and the upper surface of the lower mesh belt 2 after they are separated from the mesh belt 2, while avoiding blockage due to insufficient space.

[0036] In some embodiments, the surface of the rice noodle separating roller 4 is provided with an anti-sticking layer 403.

[0037] The anti-stick layer 403 can effectively prevent the rice noodle sheet from tearing or deforming due to adsorption during the separation process, ensuring its complete detachment. For example, the anti-stick layer 403 is made of a strip of cloth soaked in edible oil or a food-grade silicone sleeve, which can ensure low friction when in contact with the rice noodle sheet, meet food safety production requirements, and avoid contamination.

[0038] In some embodiments, the surface of the rice noodle separating roller 4 is uneven (not shown in the figure) to reduce the contact area between the separating roller and the rice noodle.

[0039] The uneven structure can also form tiny support points as the powder passes through, further reducing the risk of sticking and improving separation efficiency.

[0040] For example, the surface of the separating roller is uniformly arranged with protrusions and grooves, which are arranged alternately to form a regular mesh texture. The protrusions and grooves are circular or elliptical in shape.

[0041] The rice noodle sheets output from the steamer are very wet, so the surface of the first rice noodle sheet separating roller 4 is covered with multiple crossbars 402 and a low-stick material. The rice noodle sheet separating roller 4 at the end of the top layer mesh belt 2 includes a main shaft 401. Mounting plates 404 are installed at both ends of the main shaft 401. Multiple crossbars 402 are fixed between the mounting plates 404. The multiple crossbars 402 are arranged in a ring coaxial with the main shaft 401. An anti-stick layer 403 is provided on the crossbars 402.

[0042] The main shaft 401 is connected to the frame at both ends via bearing seats. The end of the main shaft 401 is synchronously connected to the drive roller 3 of the top layer mesh belt 2 via sprocket 6 and chain 5, ensuring that the separation action is consistent with the running rhythm of the mesh belt 2. When the top layer mesh belt 2 rotates, it drives the drive roller 3 to rotate, which in turn causes the main shaft 401 to rotate synchronously via chain 5. The mounting plate 404 and crossbar 402 on the main shaft 401 rotate accordingly. During rotation, the crossbar 402 applies a gentle pushing force to the powder skin that has detached from the mesh belt 2, guiding it to fall smoothly into the lower mesh belt 2. The anti-stick layer 403 effectively prevents the powder skin from sticking or wrinkling during the transfer process.

[0043] For example, the mounting plate 404 is configured as an annular plate, with a coaxial fixing sleeve fixed in the middle of the annular plate. The fixing sleeve is fitted onto the main shaft 401. The annular plate is located on both sides of the mesh belt 2 so that the annular plate will not obstruct the operation of the mesh belt 2. The crossbar 402 is a circular rod, and both ends of the crossbar 402 are fixedly connected to the through holes on the mounting plate 404 by bolts to ensure that the structure is stable and easy to disassemble and maintain. The anti-stick layer 403 is made of food-grade silicone sleeve or oil-soaked cloth strips.

[0044] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. In the absence of conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
