Description

Technical Field

[0001] This utility model relates to the field of non-fried instant noodle production technology, and in particular to a conveying device inside a non-fried instant noodle steamer. Background Technology

[0002] In the production of non-fried instant noodles, the dough is first kneaded and then placed in an extruder. The extruder then extrudes the dough into noodles of uniform thickness. The extruded noodles need to pass through a long steamer to be steamed. After steaming, the noodles need to be dried and cut to finally form non-fried instant noodles.

[0003] In actual production, noodles to be steamed are typically conveyed to a steaming chamber via a conveyor system for steam heating. This conveyor system often employs a metal mesh belt structure. During noodle processing, the noodles are laid on the mesh conveyor belt, and steam is then introduced into multiple air inlets to cook the noodles placed on the belt. The mesh belt has a certain open area ratio, ensuring the noodles can be supported while allowing steam to penetrate, thus achieving simultaneous steaming from both above and below. While this structure can meet steaming requirements in most cases, it still has certain technical limitations in practical applications.

[0004] Specifically, although the conveyor belt has multiple steam vents, its structure is inevitably composed of woven metal wires or linked chains, forming a certain proportion of solid support areas. When the bottom of the noodles comes into direct contact with these solid parts (such as metal cross joints, frame skeletons, etc.), the corresponding areas will hinder steam penetration, causing the steam to not fully contact the bottom of the noodles, resulting in uneven cooking. This manifests as some noodles being undercooked at the bottom, affecting the subsequent drying process and the final product's rehydration effect, reducing product consistency and quality stability.

[0005] Therefore, how to solve the problem that steam cannot penetrate evenly at the microscopic level due to the obstruction of the conveyor belt structure has become one of the important technical aspects that urgently need to be optimized in non-fried instant noodle production lines. Utility Model Content

[0006] The purpose of this invention is to solve the problem in the prior art that steam cannot penetrate evenly at the microscopic level due to the obstruction of the conveyor belt structure, and to propose a conveying device for non-fried instant noodles in a steamer.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A conveying device for a non-fried instant noodle steamer includes a conveyor belt running through the steamer. The portion of the conveyor belt inside the steamer is provided with several suspended units. Each suspended unit includes a continuously arranged inclined rising section and an inclined folding section. Two adjacent suspended units are defined as an upstream unit and a downstream unit. There is a clearance space between the inclined folding section of the upstream unit and the inclined rising section of the downstream unit.

[0009] A steam-assisted injection assembly is provided within the clearance space, which is capable of injecting steam into the noodles at the opening of the clearance space.

[0010] The steam-assisted injection assembly includes a split pipe connected to the outlet of the steam generator, and the split pipe is connected to and installed with a plurality of steam injection pipes. The steam injection pipes are placed within the clearance space and have a plurality of injection holes.

[0011] The injection hole is set away from the open space of the avoidance area.

[0012] The steam-assisted injection assembly includes an arc-shaped reflector plate corresponding to a steam injection pipe, the injection hole points to the arc-shaped reflector plate, and the open side of the arc-shaped reflector plate points to the open position of the clearance space.

[0013] A mesh plate is installed inside the arc-shaped reflector, and there is a reflection space between the mesh plate and the inner arc wall of the arc-shaped reflector. The spray hole points towards the mesh plate.

[0014] The arc-shaped reflector is inclined and has a high end and a bottom end. A liquid collection box is installed at the bottom end of the arc-shaped reflector.

[0015] This invention proposes a non-fried instant noodle steaming device with the following advantages: When the noodles slide down from the end of the inclined folding section of the upstream unit, they temporarily leave the support of the conveyor belt and enter the gap area between the front sections of the inclined rising section of the downstream unit, i.e., the clearance space. Within this clearance space, the noodles are briefly suspended, and neither their upper nor lower surfaces are in direct contact with the conveyor belt. Because this area is an open air area, the steam in the steaming chamber can freely penetrate and evenly act on the entire surface of the noodles, especially the bottom area, which was previously difficult to heat sufficiently due to the solid metal parts of the conveyor belt. This structural design effectively solves the problem of uneven steaming caused by the metal interwoven solid parts of traditional conveyor belts blocking steam. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4 A non-fried instant noodle steamer conveying device includes a conveyor belt 2 that runs through the steamer 1. The steamer has a steam injection device inside, which can be achieved using existing injection schemes. This device is mainly an improvement on the conveying device. The part of the conveyor belt 2 inside the steamer 1 is provided with several suspended units 3. The suspended unit 3 includes a continuously arranged inclined rising part 4 and an inclined turning part 5. Two adjacent suspended units 3 are defined as an upstream unit and a downstream unit. There is a clearance space 6 between the inclined turning part 5 of the upstream unit and the inclined rising part 4 of the downstream unit.

[0023] In this device, noodles are conveyed from one end of the steaming chamber to the other along a conveyor belt. The conveyor belt has multiple suspended units inside the steaming chamber. Each suspended unit consists of an inclined rising section and an inclined folding section, forming a continuous zigzag conveying path. When the noodles slide down from the end of the inclined folding section of the upstream unit, they temporarily leave the support of the conveyor belt and enter the gap area between the front sections of the inclined rising sections of the downstream units, i.e., the clearance space.

[0024] Within the clearance space, the noodles are briefly suspended, with neither their upper nor lower surfaces in direct contact with the conveyor belt. Because this area is an open space, steam from the steamer can freely penetrate and evenly distribute heat across the entire surface of the noodles, especially the bottom area which was previously difficult to heat sufficiently due to the solid metal parts of the conveyor belt. This structural design effectively solves the problem of uneven steaming caused by the interwoven metal parts of traditional conveyor belts blocking steam.

[0025] A steam-assisted injection assembly 7 is located within the clearance space 6. This assembly can inject steam into the noodles at the open portion of the clearance space 6. When the noodles are suspended in the clearance space, the steam-assisted injection assembly, situated within this space, can precisely inject steam onto the surface of the suspended noodles, particularly the bottom area. Since the noodles are not in contact with the conveyor belt at this time, both their upper and lower surfaces are exposed to the steam flow field, allowing the steam to act evenly on the entire surface of the noodles without physical obstruction.

[0026] The steam-assisted injection component uses directional injection to enhance the heating of the suspended noodles, ensuring they are fully heated in a short time and effectively compensating for the insufficient heating of the bottom surface caused by the obstruction of traditional mesh belts.

[0027] The steam-assisted injection assembly 7 includes a branch pipe 8 connecting to the outlet of the steam generator. The branch pipe 8 connects to and installs several steam injection pipes 13, which are located within a clearance space 6. Each steam injection pipe 13 has several injection holes 15. The steam-assisted injection assembly guides and distributes the steam output from the steam generator to the multiple steam injection pipes via the branch pipe. The injection pipes are arranged within the clearance space, close to the path through which the noodles travel. Each injection pipe has multiple injection holes, through which steam is ejected at a certain angle and pressure, directly acting on the suspended noodles within the clearance space.

[0028] The jet nozzle 15 is positioned away from the clearance space 6, ensuring that the steam does not directly impact the suspended noodles but instead enters the clearance space indirectly. This structure avoids problems such as overcooking of noodles caused by direct steam injection.

[0029] The steam-assisted injection assembly 7 includes arc-shaped reflectors 10 corresponding to the steam injection pipes 13. Injection holes 15 point towards the arc-shaped reflectors 10, and the open side of the arc-shaped reflectors 10 points towards the open position of the clearance space 6. With the steam injection holes pointing towards the arc-shaped reflectors, the ejected steam first impacts the inner surface of the arc-shaped reflectors, then, after guidance and diffusion, turns towards the open area of ​​the clearance space, contacting the surface of the suspended noodle. Through this indirect reflection, the steam achieves uniform distribution while changing direction, thus avoiding the localized impact and uneven heating problems caused by direct injection.

[0030] A mesh plate 12 is installed inside the arc-shaped reflector 10, and a reflection space 11 exists between the mesh plate 12 and the inner arc wall of the arc-shaped reflector 10. The injection hole 15 points towards the mesh plate 12. When steam is ejected from the injection hole, it first strikes the mesh plate located inside the arc-shaped reflector. As a structure with a certain porosity, the mesh plate can disperse the concentrated steam, transforming it into a more uniform and gentle steam flow. As the steam passes through the mesh plate, it is dispersed and further diffused into the reflection space between the steam and the reflector, and then guided along the inner arc wall of the arc-shaped reflector to the open area of ​​the clearance space.

[0031] This structural design can effectively alleviate the problem of localized concentration during steam injection and prevent steam from directly forming a strong impingement flow.

[0032] The arc-shaped reflector 10 is inclined and has a high end and a low end. A liquid collection box 9 is connected to the low end of the arc-shaped reflector 10. The inclined arrangement of the arc-shaped reflector gives it the structural characteristics of a high end and a low end. During steam injection, after steam impacts the surface of the mesh plate or reflector, it will condense into liquid water on the inner wall of the reflector due to cooling or pressure changes. By connecting the low end of the reflector to the liquid collection box, this condensed water can be guided and collected in a timely manner, preventing it from flowing arbitrarily inside the device.

[0033] During operation, the noodles enter the steaming area of ​​the steamer via a conveyor belt. The conveyor belt contains multiple suspended units, connected sequentially by inclined rising sections and inclined folding sections, forming a segmented structure. As the noodles slide from the upstream unit to the downstream unit during transport, they pass through the clearance space between the two units, where they are briefly suspended. At this point, the bottom of the noodles is no longer attached to the conveyor belt and is fully exposed to the steam environment.

[0034] To enhance the steam's effect within the clearance space, the device incorporates a steam-assisted injection assembly. This assembly connects to a steam source via a branch pipe, supplying steam to multiple injection pipes positioned within the clearance space. The injection nozzles are not directly aimed at the noodles but rather positioned away from the opening of the clearance space to prevent direct steam impact. The injection nozzles face an arc-shaped reflector with a mesh panel. The steam first impacts the mesh panel, is dispersed by it, and then enters the reflection space between the arc-shaped reflector and the mesh panel. From there, the steam is guided by the arc-shaped reflector to the opening of the clearance space, ultimately acting on the suspended noodles in a gentle and uniform manner.

[0035] The curved reflector is arranged at an angle, and its bottom is connected to a liquid collection box to collect the liquid water generated by the condensation of steam during the reflection process, preventing the condensate from dripping randomly and contaminating the noodles or accumulating inside the equipment.

[0036] Through the above structural combination, the device creates multiple short-term steam-enhancing zones during the natural conveying of noodles, significantly improving the heating effect at the bottom of the noodles. The entire heating process is more uniform, avoiding the localized undercooking phenomenon caused by the solid obstruction of traditional conveyor belts, which helps to improve the processing quality and production yield of non-fried instant noodles.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
