Description

Technical Field

[0001] This invention relates to the field of food processing technology, and more specifically, to an automatic production line and processing method for dried noodles. Background Technology

[0002] As a traditional staple food widely loved by the public, dried noodles have a huge consumer market worldwide. For a long time, the production method of dried noodles has evolved from purely manual to mechanized production. In the early days, handmade noodles dominated, with skilled craftsmen relying on their rich experience and expertise, devoting a great deal of manpower and time to each step, from kneading and rolling the dough to cutting it. While this method produced noodles with a unique flavor, its production efficiency was extremely low; a skilled craftsman could only produce a limited number of noodles per day, making it difficult to meet the large-scale market demand. Moreover, manual operation is greatly affected by human factors; noodles made by different craftsmen, or even by the same craftsman under different conditions, showed significant differences in thickness, width, and texture, resulting in a lack of stability and consistency in noodle quality.

[0003] With the development of technology, mechanized equipment has been gradually applied to noodle production, such as simple noodle presses and cutters. These devices have improved production efficiency and reduced manual labor intensity to some extent. However, existing noodle production equipment and processes still have many problems that urgently need to be solved, which stands in stark contrast to the beneficial effects of this invention patent.

[0004] In terms of production efficiency and labor costs, most noodle production equipment only automates certain processes. For example, while some noodle presses can press dough sheets, processes such as dough preparation, subsequent conveying and cutting of dough sheets still require significant manual labor. This not only wastes manpower but also hinders production efficiency due to untimely manual operations, resulting in high labor costs and severely restricting the large-scale development of noodle production enterprises.

[0005] In terms of the stability of noodle quality, traditional noodle-pressing equipment typically uses a parallel roller structure, resulting in uneven stress on the dough during pressing and causing inconsistent noodle sheet thickness. In subsequent slitting and cutting stages, due to limited equipment precision, it's difficult to standardize the width and length of the noodles, significantly impacting the product's appearance and taste consistency, and failing to meet consumer demand for high-quality noodles.

[0006] Preventing dough sheets from sticking together has always been a challenge in noodle production. Existing production equipment lacks effective anti-sticking measures during the dough sheet pressing process, or only applies flour sparingly in a few stages, failing to fully cover the entire process of dough sheet conveying and pressing. This makes the dough sheets prone to sticking together in subsequent processing, increasing the workload of manual dough separation and often causing dough sheet damage, reducing product qualification rates, and affecting production continuity.

[0007] In terms of automation, most existing noodle production equipment relies on manual real-time monitoring and operation adjustments. For example, during the noodle pressing process, manual observation of the dough tension and manual adjustment of equipment parameters are required based on experience. If manual monitoring is inadequate, problems such as dough breakage or excessive tightness and wrinkling can easily occur. In addition, equipment operation status monitoring and fault warning also rely on manual inspection, which cannot detect potential problems in time, leading to production interruptions, increased maintenance costs, and the lack of ease of operation and automation is far from meeting the needs of modern production.

[0008] In terms of structural design and conveying stability, the connections between various mechanisms in existing noodle production equipment are not reasonable enough, and the transition devices are poorly designed. Noodle sheets or hanging noodles are prone to falling or shifting during transport between mechanisms, affecting smooth production. The unreasonable layout of conveying components such as the drying conveyor belt prevents them from accurately receiving noodles completed in previous processes, leading to unstable noodle conveying, increased production losses, and reduced overall equipment reliability and production efficiency.

[0009] In summary, traditional noodle production methods and existing equipment have many shortcomings in terms of production efficiency, product quality, anti-sticking measures, level of automation, and structural design. The automatic noodle production line of this invention was developed to solve these problems, aiming to provide the noodle production industry with an efficient, stable, intelligent, and structurally sound production solution.

A pressing roller 1 is installed on the pressing support 1 and a pressing roller 2 is installed on the pressing support 2. The pressing roller 1 and the pressing roller 2 are not parallel and are placed on the upper part of the conveyor belt. A pressing roller drive motor is connected to the end of the pressing roller 1 and the pressing roller 2.

[0020] Preferably, the multi-stage thinning mechanism includes at least three thinning frames, each frame being equipped with an upper pressure roller and a lower pressure roller. One end of each upper and lower pressure roller is fitted with a transmission gear of the same type, and the transmission gears are connected to each other through gear meshing. The other end of the lower pressure roller is equipped with a transmission wheel, which is connected to a thinning drive motor located at the bottom of the thinning frame via a transmission component.

[0021] The multi-stage pressing mechanism also includes a sheet conveying assembly, which includes a first conveyor frame and a second conveyor frame. Rotating rollers are rotatably installed on both the first and second conveyor frames, and the same pressing conveyor belt is driven onto both the first and second conveyor frames.

[0022] Preferably, each of the thinning frames is equipped with a photoelectric sensor on its top. The photoelectric sensor is used to detect the tension state of the sheet and adjust the speed of the drive motor of the next-stage thinning mechanism.

[0023] Preferably, a first flour spreading assembly is provided in the middle of the frontmost thinning frame. The first flour spreading assembly includes a flour hopper fixedly installed on the frame. The bottom of the flour hopper is arc-shaped and has a through hole for flour to pass through on the arc-shaped bottom surface. A brush roller is rotatably installed on the lower part of the flour hopper. The brush roller is provided with multiple sets of brushes and the brushes can contact the inner bottom surface of the flour hopper.

[0024] Preferably, a coating component with the same structure as the first coating component is provided in the middle of the second front-end thinning frame, and a second coating component is provided above the rear of the thinning frame. The second coating component has the same structure as the first coating component.

[0026] Preferably, the slitting mechanism includes a slitting frame, on which a pair of slitting cutter rollers are arranged in close cooperation with each other, and the surface of the slitting cutter rollers is provided with slitting cutters; one end of each slitting cutter roller is provided with a slitting drive gear, and the slitting cutter rollers are driven by the meshing of the slitting drive gears; one end of a slitting guide roller is connected to a slitting encoder arranged on one side of the slitting frame.

[0027] Preferably, the cutting mechanism includes a cutting frame, an electric telescopic rod is fixedly installed on the upper part of the cutting frame, and a cutting blade is fixedly installed at the end of the electric telescopic rod.

[0028] Preferably, the hanging mechanism includes two hanging transport frames, which are connected by the same transport chain. The transport chain is provided with hooks at intervals to facilitate the hanging of the noodle drying rack. A noodle drying rack is provided at the tail end of the hanging transport frame away from the slitting machine frame. The hanging mechanism also includes a hanging photoelectric sensor, which is located at the tail end of the slitting machine frame and is used to detect the hanging and rising state of the noodle drying rack, while providing an opening and closing signal to the hanging drive motor.

[0029] A method for processing dried noodles, using the aforementioned automated production line, includes the following steps:

[0030] Step 1: The dough enters the primary dough pressing mechanism through the feeding device. The dough pressing motor drives the rotating shaft one or rotating shaft two to rotate, causing the conveyor belt to run. At the same time, the dough pressing roller drive motor drives the dough pressing roller one and dough pressing roller two to rotate, and the dough is pressed in a staggered manner to form a dough sheet.

[0031] Step 2: The sheet enters the multi-stage pressing mechanism through the transition plate, and is gradually pressed thin by the upper and lower pressure rollers on at least 3 stages of the pressing frame. During the pressing process, the photoelectric sensor detects the tension of the sheet and adjusts the speed of the next stage pressing drive motor. The sheet is also spread with a first- or second-stage spreading component to prevent sticking.

[0032] Step 3: The pressed dough sheet enters the drying mechanism through the transition plate. The drying conveyor belt receives the dough sheet and runs, while the blower and heating wire work together to perform preliminary drying.

[0033] Step 4: After preliminary drying, the dough sheets enter the slitting mechanism via a transition plate, where the slitting rollers cut the dough sheets into noodles;

[0034] Step 5: After being slit, the noodles enter the cutting mechanism through the transition plate. The electric telescopic rod drives the cutting blade to cut the noodles into the set length.

[0035] Step Six: After the noodles are cut, they are hung on the noodle drying rod. After the hanging photoelectric sensor detects the hanging status of the noodle drying rod, the hanging drive motor drives the conveyor chain to transport the noodle drying rod with the noodles to the noodle drying rack for drying.

[0036] Compared with existing technologies, the beneficial effects of this invention are:

[0037] 1. The production of dried noodles has been automated. From the initial pressing of the dough, multi-stage thinning, drying, slitting, cutting to the final hanging and drying, the entire process does not require much manual intervention, which greatly improves production efficiency and reduces labor intensity.

[0038] In the primary dough pressing mechanism, the first and second pressing rollers are not parallel, which allows for staggered pressing of the dough sheet, making the initial dough sheet more uniform. The multi-stage thinning mechanism, through at least three stages of thinning and in conjunction with photoelectric sensors to adjust the running speed in real time, ensures that the thickness of the dough sheet is uniform and consistent, thus improving the quality of the noodles.

[0039] 3. A flour-sprinkling component is installed in the primary and secondary pressing mechanisms, which can sprinkle flour in a timely manner during the conveying and pressing of the dough sheets, effectively preventing the dough sheets from sticking together and ensuring smooth production.

[0040] 4. The various mechanisms are connected by transition plates, which makes the conveying of dough sheets or noodles between the mechanisms more stable and reduces losses during the production process.

[0041] 5. The hanging mechanism is equipped with a hanging photoelectric sensor, which can automatically detect the hanging status of the drying rack and control the start and stop of the hanging drive motor, making the hanging process more intelligent and automated. Attached Figure Description

The hanging mechanism also includes a hanging photoelectric sensor 65, which is located at the tail end of the slitting machine frame and is used to detect the hanging and rising state of the noodle drying rods, while providing an opening and closing signal to the hanging drive motor.

[0076] The automated noodle production line in the above embodiments achieves automated production from dough to finished noodles through the coordinated operation of various mechanisms. The specific working principle is as follows:

[0077] First, the dough enters the primary dough pressing mechanism 1 via the feeding device. The dough pressing motor 15 starts, driving either shaft 12 or shaft 13 to rotate, which in turn causes the conveyor belt 14 to rotate, conveying the dough forward. At the same time, the dough pressing roller drive motor 18 drives dough pressing rollers 1 and 2 to rotate. Since the two are not parallel, they perform staggered pressing on the passing dough (unidirectional pressing can easily result in one side being thinner than the other), initially pressing the dough into a sheet, which continues to be conveyed by the conveyor belt 14.

[0078] Next, the dough sheet enters the multi-stage pressing mechanism 2 through the transition plate 7. Guided by the transition plate 7, the dough sheet is conveyed between the upper pressure roller 22 and the lower pressure roller 23 of the pressing frame. The pressing drive motor 25 drives the transmission wheel 24 to rotate through the transmission component, which in turn causes the lower pressure roller 23 to rotate. The lower pressure roller 23 drives the upper pressure roller 22 to rotate synchronously through the transmission gear, performing the first pressing of the dough sheet. Subsequently, at the foremost pressing frame 21, the first flour spreading component 28 starts working. Flour in the flour hopper 281 leaks through the through hole, and the brush roller 283 rotates, with its surface brush evenly spreading the flour onto the pressing conveyor belt 264. When the dough sheet after the first pressing falls onto the conveyor belt, it prevents the back of the dough sheet from sticking. The pressed dough sheet is then conveyed by the pressing conveyor belt 264 to the next pressing frame.

[0079] When the second thinning frame 21 at the front end is working, the dough sheet is thinned again by the upper pressure roller 22 and the lower pressure roller 23. The first coating assembly 28 in the middle coats the dough sheet on the back side, while the second coating assembly 29 at the top coats the dough sheet on the top surface, preventing the dough sheets from sticking together during subsequent thinning processes.

[0080] Meanwhile, the photoelectric sensor 27 at the top of each thinning frame detects the tension of the sheet in real time. When the sheet is detected to be taut, a signal is sent to adjust the speed of the next-stage thinning drive motor 25 to ensure that the sheet maintains appropriate tension during at least three stages of thinning, ultimately forming a sheet of the required thickness.

[0081] The thinned dough sheet is conveyed to the drying mechanism 3 via the transition plate 7. The starting end of the drying conveyor belt 343 is located below the end of the thinning conveyor belt 264 at the end of the thinning mechanism, receiving the dough sheet and rotating under the drive of the drying conveyor drive motor. At the same time, the blower fan 32 and the heating wire 33 are working. The heating wire 33 is energized and heats up, and the blower fan 32 blows heat onto the dough sheet to dry it and remove excess moisture.

[0082] After drying, the dough sheet enters the slitting mechanism 4 via the transition plate 7. The slitting drive motor 41 starts, driving one of the slitting cutter rollers 42 to rotate. This slitting cutter roller drives the other slitting cutter roller 42 to rotate synchronously through the slitting transmission gear. The slitting cutters on the surfaces of the pair of slitting cutter rollers 42 cooperate with each other to cut the dough sheet into multiple strips of noodles.

[0083] After being slit, the noodles enter the cutting mechanism 5 through the transition plate 7. When the noodles are conveyed to the area below the cutting blade 53, the electric telescopic rod 52 extends and retracts, causing the cutting blade 53 to move up and down, cutting the noodles into a set length. Here, the noodle conveyor belt will run at equal distances under the encoder setting, thus achieving the same length of noodles.

[0084] The cut noodles continue to move forward. When the noodles hang to the middle position, the hanging photoelectric sensor 65 detects the position of the noodles and provides a start signal to the hanging drive motor. The hanging drive motor drives the conveyor chain 62 to rotate. The hook 63 on the conveyor chain 62 hooks the noodle drying rod and moves the noodle drying rod upward. After the noodles are hung on, they wait for the next step of movement. They are conveyed along the two hanging conveyor frames 61 and finally sent to the noodle drying rack 64 at the end for drying, completing the entire noodle production process.

[0085] In the above embodiments and working principles, this device realizes the automation of noodle production. From the initial pressing of the dough, multi-stage thinning, drying, slitting, cutting to the final hanging and drying, the entire process does not require much manual intervention, which greatly improves production efficiency and reduces labor intensity.

[0086] In the primary dough pressing mechanism, the first and second pressing rollers are not parallel, which allows for staggered pressing of the dough sheet, making the initial dough sheet more uniform. The multi-stage thinning mechanism, through at least three stages of thinning and in conjunction with photoelectric sensors to adjust the running speed in real time, ensures that the thickness of the dough sheet is uniform and consistent, thus improving the quality of the noodles.

[0087] A flour-sprinkling component is installed in the primary and secondary pressing mechanisms to sprinkle flour at appropriate times during the conveying and pressing of the dough sheets, effectively preventing the sheets from sticking together and ensuring smooth production.

[0088] The various mechanisms are connected by transition plates, which makes the conveying of dough sheets or noodles between the mechanisms smoother and reduces losses during the production process.

[0089] The hanging mechanism is equipped with a hanging photoelectric sensor, which can automatically detect the hanging status of the drying rack and control the start and stop of the hanging drive motor, making the hanging process more intelligent and automated.

10. A method for processing dried noodles, characterized in that, The automatic noodle production line according to claim 1 includes the following steps: Step 1: The dough enters the primary dough pressing mechanism through the feeding device. The dough pressing motor drives the rotating shaft one or rotating shaft two to rotate, causing the conveyor belt to run. At the same time, the dough pressing roller drive motor drives the dough pressing roller one and dough pressing roller two to rotate, and the dough is pressed in a staggered manner to form a dough sheet. Step 2: The sheet enters the multi-stage pressing mechanism through the transition plate, and is gradually pressed thin by the upper and lower pressure rollers on at least 3 stages of the pressing frame. During the pressing process, the photoelectric sensor detects the tension of the sheet and adjusts the speed of the next stage pressing drive motor. The sheet is also spread with a first- or second-stage spreading assembly to prevent sticking. Step 3: The pressed dough sheet enters the drying mechanism through the transition plate. The drying conveyor belt receives the dough sheet and runs, while the blower and heating wire work together to perform preliminary drying. Step 4: After preliminary drying, the dough sheets enter the slitting mechanism via a transition plate, where the slitting rollers cut the dough sheets into noodles; Step 5: After being slit, the noodles enter the cutting mechanism through the transition plate. The electric telescopic rod drives the cutting blade to cut the noodles into the set length. Step Six: After the noodles are cut, they are hung on the noodle drying rod. After the hanging photoelectric sensor detects the hanging status of the noodle drying rod, the hanging drive motor drives the conveyor chain to transport the noodle drying rod with the noodles to the noodle drying rack for drying.
