Description

Technical Field

[0001] This application relates to the field of rice noodle production equipment, and more particularly to a conveying mechanism for rice noodles, a method for processing bamboo segments, and a production line. Background Technology

[0002] Bamboo pole rice noodles are a special type of fresh rice noodles with intangible cultural heritage status. They are similar in shape to flat rice noodles and have a unique bamboo aroma, which differentiates them from ordinary rice noodles.

[0003] The traditional production process of bamboo rice noodles involves soaking rice, grinding into a paste, rinsing the paste (mixing peanut oil with pure rice paste and rinsing it back and forth between utensils more than ten times), steaming, manual cooling (manually drying the rice noodles on bamboo poles), cutting into strips, and packaging. Existing technology has several technical drawbacks: 1. Relying on manual drying of the rice noodles on bamboo poles to impart a bamboo aroma makes large-scale production difficult; 2. During manual cooling, the rice noodles hang unevenly on the bamboo poles, resulting in inconsistent and poor absorption of the bamboo aroma, leading to poor product taste and flavor stability. Summary of the Invention

[0004] This application provides a conveying mechanism for rice noodles, a method for processing bamboo segments, and a production line that can integrate conveying, drying, and aroma enhancement.

[0005] In a first aspect, this application provides a conveying mechanism for rice noodles, including a carrier for carrying rice noodles. The carrier includes an outer surface made of bamboo, which is in direct contact with the rice noodles. The carrier drives the rice noodles to move along the conveying direction to a predetermined position.

[0006] Preferably, the rice noodles include steamed bamboo shoot powder, which is then transferred to the outer surface of the carrier.

[0007] Preferably, the conveying mechanism is configured as a roller conveyor, the bearing component is configured as the roller of the roller conveyor, and the outer surface made of bamboo is configured as the outer circumferential surface of the roller.

[0008] Preferably, the roller conveyor mechanism includes a frame, rollers, and a drive assembly; multiple rollers are spaced apart on the frame along the conveying direction, and the drive assembly is connected to the rollers to drive the rollers to rotate, thereby moving the rice noodles along the conveying direction.

[0009] Preferably, the roller comprises circular bamboo segments, the outer surface of which is used for direct contact with the rice noodles.

[0010] Preferably, a rotating component is provided at both ends of the bamboo segment along its axial direction. The rotating component is rotatably connected to the frame. A sprocket is coaxially provided on the rotating component. The drive component is connected to the sprocket and drives the bamboo segment to rotate through the sprocket.

[0011] Preferably, the connection method between the rotating component and the bamboo segment includes: the rotating component is sleeved on the outer circumference of the bamboo segment, or the rotating component is supported on the inner circumference of the bamboo segment.

[0012] Preferably, food-grade silicone is used to bond the rotating part to the bamboo segment.

[0013] Secondly, this application provides a method for processing bamboo segments, the method comprising: Step S100: Selection of bamboo segments: Select raw bamboo with a growth age of 3 to 8 years as bamboo segment blanks, remove the internode cavities and insect-infested parts of the bamboo segment blanks, and detect the internal cracks of the bamboo segment blanks through flaw detection. If the internal cracks reach the set standard, the bamboo segment blanks are discarded. Step S200, Bamboo segment processing: Cut all the bamboo segment blanks into multiple bamboo segments of equal length, and process the outer diameter of each bamboo segment so that the outer diameter error of each bamboo segment does not exceed 2mm; Step S300, processing of bamboo segments, includes: Step S310: Spray the bamboo sections with a diluted solution of neutral food-grade degreasing agent to remove surface grease and stains, then rinse with running water and place them in a cool, ventilated place to air dry until the moisture content is 18%-22%. Step S320: Use microwave to heat the bamboo section to pre-carbonize it, setting the temperature to 120℃ to 150℃, the time to 10min to 20min, and the power to 3kW to 4kW. Step S330: After natural cooling, quickly rinse the surface of the bamboo section with warm water at 40℃ to 70℃ to remove the charcoal powder, and then air dry in a cool and ventilated place. Step S340: Apply a thin layer of peanut oil to the outer surface of the bamboo section; Step S350: Coat the outer surface of the bamboo segment with a lubricating protective layer. After the lubricating protective layer has cured, the bamboo segment can be used as a roller in the roller conveyor mechanism.

[0014] Thirdly, this application provides a rice noodle production line, comprising: The rice noodle steaming mechanism includes a steaming conveyor line and a steaming component. The steaming conveyor line is used to convey rice noodles in a predetermined direction, and the steaming component is connected to the steaming conveyor line to heat the rice noodles so that the rice noodles are steamed. A roller conveyor mechanism is provided at an interval from the tail end of the steaming conveyor line. The guide sloping plate is set at the end of the steaming conveyor line and between the roller conveyor mechanism along the conveying direction. It is used to guide the steamed rice noodles obliquely downward to the rollers of the roller conveyor mechanism. The conveying speed of the steaming conveyor line is the same as the conveying speed of the roller conveyor mechanism.

[0015] The conveying mechanism, processing method, and production line of this application have at least the following beneficial effects: (1) In the conveying mechanism of this application, bamboo material is used as part of the conveying mechanism in an innovative way. The rice noodles are directly transferred to the carrier of the conveying mechanism. At least part of the carrier is made of bamboo material. The rice noodles are in direct contact with the bamboo material of the carrier, and the carrier drives the rice noodles to move toward the predetermined position. The three-in-one effect of conveying, drying and adding fragrance can be achieved. From the perspective of conveying, the manual transfer method is eliminated and mechanized conveying is adopted. Fragrance is added and drying is carried out during the conveying process. It can adapt to large-scale automated production and improve production efficiency. From the perspective of drying, since the rice noodles are directly laid on the outer surface of the bamboo, the taste problem caused by uneven force can be avoided. It can also increase the effective drying area. From the perspective of adding fragrance, the rice noodles are directly laid on the surface of the bamboo, and the contact area is much larger than that of hanging on the bamboo pole. It can improve the fragrance effect and the uniformity of the fragrance.

[0016] (2) The conveying mechanism of this application is configured as a roller conveying mechanism, and the bearing component is configured as a roller. Multiple bamboo rollers are in continuous contact with rice noodles during the rolling process. Under the action of contact friction and slight heat, the fragrance of bamboo is evenly transferred to the rice noodles, resulting in better fragrance consistency.

[0017] (3) The processing method of this application can process bamboo segment blanks and ultimately form bamboo segments that are suitable for food and conveying mechanisms.

[0018] (4) The production line of this application adopts a combination of rice noodle steaming mechanism and roller conveyor mechanism. The rice noodle slurry enters the range of the steaming component under the drive of the steaming conveyor line. The steaming component heats the rice noodle slurry to form it and continuously conveys it to the tail end of the rice noodle steaming mechanism. The tail end of the rice noodle steaming mechanism is equipped with a downward guiding guide plate. The guide plate guides the free end of the steamed rice noodles to the roller of the roller conveyor mechanism. Since the conveying speed of the steaming conveyor line is the same as the conveying speed of the roller conveyor mechanism, the rice noodles can be smoothly and continuously transferred to the roller through the guide plate and conveyed forward, thereby realizing automated production. The steamed rice noodles are easier to absorb flavor and are evenly coated with aroma when combined with the rolling bamboo roller. Attached Figure Description

Detailed Implementation

[0020] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0021] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0022] Example 1: like Figure 1 As shown, this embodiment discloses a conveying mechanism. The conveying mechanism 100 includes a carrier 110, which has an outer surface made of bamboo. For example, a material layer made of bamboo is disposed on the carrier 110 so that the carrier 110 has an outer surface made of bamboo. In this embodiment, rice noodles are transferred to the outer surface made of bamboo, and then the carrier 110 is driven so that the carrier 110 drives the rice noodles to move along the conveying direction and be conveyed to a predetermined position for the next processing step.

[0023] like Figure 1 As shown in (A), the conveying mechanism 100 may be a roller conveying mechanism 100a, the bearing member 110 is configured as a roller 110a of the roller conveying mechanism 100a, and the outer circumferential surface of the roller 110a is configured as an outer circumferential surface made of bamboo material.

[0024] like Figure 1 As shown in (B), the conveying mechanism 100 can also be a mesh chain conveying mechanism 100b, and the carrier 110 is configured as a bamboo mat 110b set on the mesh chain, and the bamboo mat 110b moves along the conveying direction.

[0025] The conveying mechanism 100 can also be a linear guide rail conveying mechanism, and the bearing member 110 is configured as a slide plate of the guide rail conveying mechanism, which moves along the conveying direction.

[0026] The rice noodles in this embodiment can be bamboo pole noodles or other types of rice noodles available on the market. In this embodiment, it is preferred that the rice noodles include bamboo pole noodles. After the bamboo pole noodles are steamed, they are transferred to the carrier 110 and conveyed along the conveying direction.

[0027] Example 2 like Figure 2As shown, in this embodiment, the conveying mechanism 100 is configured as a roller conveyor 100a, and the bearing member 110 is configured as the roller 110a of the roller conveyor 100a. The outer circumferential surface of the roller 110a is configured to be made of bamboo material, for example, as shown in the figure. Figure 3 As shown, a bamboo tube 110d can be coaxially fixed on the roller 110a, so that an outer circumferential surface made of bamboo material can be formed on the outer periphery of the roller 110a. Alternatively, the entire roller 110a can be made of bamboo material. In this second embodiment, it is preferable to make the entire roller 110a of bamboo material.

[0028] like Figure 2 As shown, the roller conveyor mechanism 100a includes a frame 120, rollers 110a, and a drive assembly (not shown). The frame 120 is fixedly installed in a certain working area to provide installation and support positions for the rollers 110a and the drive assembly. Multiple rollers 110a are equally spaced on the frame 120 along the conveying direction. The steamed rice noodles are transferred to the outer circumference of the rollers 110a, and the rice noodles are driven to move along the conveying direction by the rolling of the multiple rollers 110a. The drive assembly is installed on the frame 120 and is used to drive the multiple rollers 110a to rotate.

[0029] like Figure 4 As shown, in this embodiment, the roller 110a includes a circular bamboo segment 110c. The outer diameter of the bamboo segment 110c is equal everywhere. This equal outer diameter is an ideal state. In the actual processing, it can be understood that the outer diameter error of the bamboo segment 110c at each position does not exceed 2mm. After steaming (preferably steaming the rice flour), the rice flour is transferred to the outer circumference of the bamboo segment 110c. The bamboo segment 110c is rotated directly or indirectly by the drive component, thereby driving the rice flour to move forward.

[0030] like Figure 4 As shown, each bamboo segment 110c has a rotating component 130 at both ends of its axial direction. The frame 120 has rotating holes that mate with the rotating components 130. The rotating components 130 are rotatably mounted in the rotating holes. A sprocket 140 is coaxially fixed to one of the rotating components 130. The drive assembly is connected to the sprocket 140, and the drive assembly drives the bamboo segment 110c to rotate through the sprocket 140.

[0031] The connection between the rotating component 130 and the bamboo segment 110c includes the following two forms, such as... Figure 5 As shown: The first form is mainly applied when the axial end of the bamboo segment 110c is a bamboo node. The rotating component 130 includes a sprocket shaft 131, at least part of which is configured as a cylindrical shape. One end of the sprocket shaft 131 is rotatably disposed in the rotating hole of the frame 120, and the cylindrical end is coaxially sleeved on the axial end of the bamboo segment 110c. Preferably, the inner diameter of the sprocket shaft 131 is slightly smaller than the outer diameter of the bamboo segment 110c (for example, the inner diameter of the sprocket shaft 131 is 0.95 to 0.99 times the outer diameter of the bamboo segment 110c), which can form an interference fit and achieve a stable connection between the sprocket shaft 131 and the bamboo segment 110c. In some preferred embodiments, the sprocket shaft 131 and the bamboo segment 110c can also be further fastened using existing methods such as screws and clamps.

[0032] The second form is mainly applied to the case where the axial end of the bamboo segment 110c is a node. The rotating component 130 includes a circular inner support plate 132 and a rotating pin 133. The circular inner support plate 132 is coaxially disposed inside the axial end of the bamboo segment 110c. Preferably, the outer diameter of the circular inner support plate 132 is slightly larger than the inner diameter of the bamboo segment 110c (for example, the outer diameter of the circular inner support plate 132 is 1.01 to 1.2 times the inner diameter of the bamboo segment 110c) so that an interference fit is formed between the outer circumferential surface of the circular inner support plate 132 and the inner circumferential surface of the bamboo segment 110c. In some preferred embodiments, the circular inner support plate 132 and the bamboo segment 110c can be further fastened together using existing methods such as screws and clamps. The rotating pin 133 is coaxially fixedly disposed on the circular inner support plate 132 and is rotatably disposed in the rotating hole of the frame 120. If both ends of the bamboo segment 110c are internodes, the sprocket 140 is coaxially fixed on the rotating pin 133.

[0033] In this embodiment, preferably, the inner circumferential surface of the sprocket shaft 131 and the outer circumferential surface of the bamboo segment 110c can be bonded together with food-grade silicone, and the outer circumferential surface of the circular inner support plate 132 and the inner circumferential surface of the bamboo segment can also be bonded together with food-grade silicone.

[0034] In this embodiment, a complete ring chain meshes with all the sprockets 140 on the frame 120. The drive component includes a motor, and the output shaft of the motor meshes with the chain so that the motor synchronously drives multiple rollers 110a (i.e. bamboo segments 110c) to rotate. The rollers 110a made of bamboo segments 110c weigh only about 1 / 4 of the weight of metal rollers of the same specifications, which can reduce the drive power and achieve energy saving.

[0035] Example 3 like Figure 6As shown, this embodiment three discloses a method for processing bamboo segment 110c. After processing the bamboo segment 110c, the bamboo segment 110c can be used on the roller conveying mechanism 100a in embodiment two and used as the rolling element (i.e., roller) of the roller conveying mechanism 100a.

[0036] The processing methods include: Step S100 for selection: Select raw bamboo with a growth age of 3 to 8 years as bamboo segment blanks, or select raw bamboo with a fiber density ≥ 0.8 g / cm³ as bamboo segment blanks. The number of bamboo segment blanks is selected according to actual needs. Screen the selected bamboo segment blanks and select all bamboo segment blanks with an outer diameter of 5 cm to 15 cm. Then remove the internode voids and insect-infested parts of the bamboo segment blanks. Detect the internal cracks of the bamboo segment blanks through flaw detection. If the internal cracks reach the set standard, discard the bamboo segment blank. The set standard is set according to actual needs and is not limited here.

[0037] Step S200 for processing bamboo segment blanks: Divide all bamboo segment blanks into multiple bamboo segments 110c of equal length. The specific length is selected according to actual needs, generally within the range of 12cm to 35cm. The outer diameter of the bamboo segment 110c is processed by lathe or machining equipment to process each bamboo segment 110c into equal diameter. Equal diameter here is an ideal state. Generally, it is required that the outer diameter error of each bamboo segment 110c does not exceed 2mm.

[0038] Step S300 is used to process the machined bamboo segment 110c. Step S300 includes steps S310, S320, S330, S340 and S350. Step S310 (preliminary cleaning): Spray the bamboo section 110c with a 1:200 diluted solution of a neutral food-grade degreaser (NSF A1 certified) for 3-5 minutes (e.g., 3 minutes) to remove grease and stains from the surface. Rinse repeatedly with running water until no foam residue remains. After the pH value is tested and found to be neutral (6.5-7.5), place the bamboo section 110c in a cool, ventilated place to air dry until the moisture content is in the range of 18%-22%. In this embodiment, the moisture content range is an important parameter, as it affects the uniformity of subsequent carbonization and the retention of bamboo fragrance. The specific values ​​of moisture content are selected, for example, 18%, 20%, or 22%.

[0039] Step S320 (pre-carbonization): Bamboo segment 110c is heated by microwave or other heating methods to pre-carbonize it. The specific heating parameters are: temperature 120℃ to 150℃, preferably 140℃, time 10min to 20min, preferably 15min, microwave power 3kW to 4kW. It is preferred to use microwave segmented heating, with 3kW power for the first 5 minutes, 4kW power for the middle 5 minutes, and 3kW power for the last 5 minutes. This can effectively kill bacteria and ensure the safety of the bamboo segment when it comes into contact with food.

[0040] Step S330 (cooling and shaping): Place the bamboo segment 110c in a specific area to cool naturally, then quickly rinse the surface charcoal powder of the bamboo segment 110c with warm water at 40℃ to 70℃. It is preferable to use warm water at 60℃ to quickly complete the rinsing within 30 seconds to avoid prolonged soaking and loss of bamboo fragrance. Then place it in a cool and ventilated place to dry for 2-4 hours to allow the aroma substances inside the bamboo to redistribute evenly.

[0041] Step S340 (fragrance locking): Apply a thin layer of peanut oil (food grade) to the outer circumference of each bamboo segment 110c to lock in the bamboo fragrance and form a non-stick protective layer. Wait for a period of time before proceeding to the next step.

[0042] Step S350 (Surface Treatment): Dilute an NSF H1 certified lubricating and protective material and spray it evenly on the outer circumference of each bamboo segment 110c. After the lubricating and protective material cures, it forms a lubricating and protective layer. Alternatively, mix food-grade beeswax and palm wax in a 1:1 ratio, heat and melt it, and then apply it evenly to the outer circumference of each bamboo segment 110c at a liquid temperature of 60°C. In this case, the food-grade beeswax and palm wax form a lubricating and protective layer after curing. After application, seal and air dry in a cool, dark place for 4 hours to ensure complete curing and avoid any sticky residue.

[0043] In this embodiment, after processing through the above steps, multiple bamboo segments 110c that can be used in the roller conveyor mechanism 100a can be obtained, which meet food safety standards and structural strength requirements.

[0044] Example 4 like Figure 7 As shown, this embodiment four discloses a rice noodle production line that can be used for the production of bamboo pole rice noodles. The production line includes a rice noodle steaming mechanism 200, a conveying mechanism 100, and a guide inclined plate 300. The conveying mechanism 100 is configured as the roller conveying mechanism 100a in embodiment two.

[0045] The rice noodle steaming mechanism 200 is used to heat the rice noodles so that they are cooked. For example, the rice noodle steaming mechanism 200 heats the rice paste on the conveyor belt by spraying high-temperature steam so that the rice paste is heated and formed into thin sheets.

[0046] The rice noodle steaming mechanism 200 includes a steaming conveyor line and a steaming component. The steaming conveyor line is configured as a conveyor belt conveyor line. The rice paste is laid on the steaming conveyor line and the steaming conveyor line drives the rice paste to move along the conveying direction. The steaming component is covered above the steaming conveyor line and is used to heat and shape the rice paste.

[0047] In this embodiment, the structure of the rice noodle steaming mechanism 200 can refer to the prior art, such as the rice noodle processing equipment with patent publication number CN105685801A, or the continuous steaming box or continuous tunnel cooking mechanism in the prior art, or the integrated steaming and waking tunnel produced by Mige Intelligent Company, etc.

[0048] like Figure 8 As shown, the roller conveyor mechanism 100a is located at the tail end of the steaming conveyor line, and the steaming conveyor line and the roller conveyor mechanism 100a are spaced apart in the conveying direction with a spacing of less than 1cm. The steamed rice noodles are conveyed forward by the steaming conveyor line to the tail end, and fall onto the roller 110a of the roller conveyor mechanism 100a through the guide plate 300 at the tail end.

[0049] The height of the roller 110a of the roller conveyor mechanism 100a is slightly lower than the upper surface of the steaming conveyor line. Here, "slightly lower" means no more than 2 cm.

[0050] like Figure 8 As shown, the guide plate 300 is located between the tail end of the steaming conveyor line and the roller conveyor mechanism 100a. Specifically, along the conveying direction, the guide plate 300 is located between the tail end of the steaming conveyor line and the roller conveyor mechanism 100a. The guide plate 300 is inclined to form a guide slope. The higher end of the guide plate 300 is connected to the tail end of the steaming conveyor line, and the lower end of the guide plate 300 is connected to the roller conveyor mechanism 100a. The free end of the steamed rice noodles falls into the guide plate 300 along the conveying direction and is guided by the guide plate 300 to the roller 110a of the roller conveyor mechanism 100a. Since the conveying speed of the steaming conveyor line is the same as the conveying speed of the roller conveyor mechanism 100a, the steamed rice noodles can be smoothly and slowly transferred to the roller conveyor mechanism 100a.

[0051] In this embodiment, preferably, three roller conveyor mechanisms 100a are provided, and the three roller conveyor mechanisms 100a are connected in sequence in the conveying direction. The rice noodles are conveyed along the conveying direction of the three roller conveyor mechanisms 100a, and the conveying speed of the roller conveyor mechanism 100a closest to the steaming conveyor line is the same as the conveying speed of the steaming conveyor line.

[0052] In this embodiment, the three roller conveyor mechanisms 100a are configured as follows: the first roller conveyor mechanism 100a closest to the steaming conveyor line is configured as a pre-drying and aroma-enhancing section, with a length of approximately 3-5m and a conveying speed range of 0.5-0.8r / min; the middle roller conveyor mechanism 100a is configured as a main drying and shaping section, with a length of approximately 5-8m and a conveying speed range of 1.0-1.2r / min; and the last third roller conveyor mechanism 100a is configured as a drying and heat preservation section, where hot air blowing or drying equipment can be installed, with a length of approximately 2-4m and a conveying speed range of 1.5-2.0r / min.

[0053] In this embodiment, the conveying speed of the three roller conveying mechanisms 100a can be adjusted independently, or the conveying speed of the three roller conveying mechanisms 100a can be adjusted to be the same.

[0054] In this preferred embodiment, when making bamboo segments, the processing scraps are collected, crushed, and placed in a breathable cloth bag. The bag is then placed in the steam channel of the rice flour steaming mechanism 200. Steam is used to fumigate the rice flour, allowing the bamboo aroma components to permeate into the rice flour paste. This achieves aroma enhancement in the pre-processing stage, compared with the aroma enhancement effect in the cooling stage, thus optimizing the consistency of flavor.

[0055] In this preferred embodiment, a bamboo powder bag is provided inside the rice flour steaming mechanism 200, and the moist steam, carrying the bamboo fragrance, permeates into the rice flour after passing through the bamboo bag.

[0056] The above description is merely a specific implementation of this application. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the protection scope of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the protection scope of this application.
