Description

Technical Field

[0001] This utility model relates to the fields of steaming equipment technology and drying equipment technology, specifically a Teflon mesh conveyor belt pre-drying steaming integrated machine. Background Technology

[0002] In the processing of dried rice noodles, steaming and drying are two key steps. There are various existing rice noodle drying equipment. For example, patent CN208983802U discloses a fully automatic multi-layer mesh chain rice noodle drying device. This device improves the drying efficiency of rice noodles and ensures drying quality through a multi-layer conveyor belt circulating drying method.

[0003] However, this type of equipment only focuses on the drying process, requiring additional equipment for the steaming of the rice noodles. This not only increases equipment costs and floor space but also prolongs the processing time and reduces production efficiency. Furthermore, most existing rice noodle steaming equipment uses a single steaming method, failing to pre-dry the rice noodles during steaming. This leads to problems such as sticking and deformation after steaming, affecting the quality and taste of the rice noodles. Moreover, existing equipment suffers from problems such as rice noodles adhering to the conveyor belt, rapid belt wear, and cleaning difficulties due to the material and structure limitations of the conveyor belt. These issues hinder the further development of the rice noodle processing industry. Therefore, there is an urgent need for a new type of equipment that integrates the steaming and pre-drying functions of rice noodles and effectively solves the problems existing in current equipment. Summary of the Invention

[0021] (III) Beneficial Effects

[0022] This utility model provides an integrated machine for pre-drying and evaporating powder using a Teflon mesh conveyor belt, which has the following beneficial effects:

[0023] 1. This utility model integrates the steaming and pre-drying functions of rice noodle sheets into one unit. By setting up multi-layer conveying components, corresponding auxiliary parts, and a rice noodle sheet steaming box within the support frame, the entire process of steaming and pre-drying rice noodle sheets can be completed in the same equipment. Traditional rice noodle sheet processing requires separate drying and steaming equipment, occupying a large production space. This utility model integrates the two functions into one device, significantly reducing the equipment's footprint and making the use of production space more efficient. Purchasing drying and steaming equipment separately not only incurs high purchase costs but also requires additional installation and maintenance expenses. This utility model, through its integrated design, reduces the need for repeated purchases and installations of equipment, lowering the overall equipment cost.

[0024] 2. In existing technology, rice noodle sheets need to be steamed in a steaming device first, and then transferred to a drying device for pre-drying. This process is not only time-consuming, but also prone to damage during the transfer. This invention can complete steaming and pre-drying in the same equipment, greatly shortening the processing flow of rice noodle sheets, improving production efficiency, and meeting the needs of large-scale production.

[0025] 3. In the conveyor assembly of this utility model, the conveyor belt is a Teflon mesh conveyor belt. Teflon material has the following significant advantages: Teflon material has excellent non-adhesive properties, effectively preventing powder sheets from adhering to the conveyor belt during transport. This not only ensures the integrity and quality of the powder sheets but also reduces the frequency of conveyor belt cleaning due to powder sheet adhesion, thus lowering maintenance costs. The Teflon mesh conveyor belt can withstand high temperatures, making it suitable for the pre-drying process of powder sheets.

[0026] 4. This utility model, by setting multiple fans inside the conveying component, enables each fan to perform uniform pre-drying of the rice noodle sheet, thereby accelerating the drying process and preventing problems such as sticking and deformation of the rice noodle sheet during the pre-drying process, thus further improving the final quality of the rice noodle sheet.

[0027] 5. The conveyor components are arranged sequentially from top to bottom, with the components on odd-numbered layers staggered horizontally from those on even-numbered layers. This design ensures that the rice noodles are evenly distributed across the multi-layered conveyor belt, preventing accumulation or overlap during transport and guaranteeing uniform pre-drying. The longitudinal arrangement of multiple conveyor components reduces the equipment's footprint. The orderly arrangement of these components extends the conveying distance of the rice noodles, prolongs the drying time, and results in a better drying effect.

[0028] 6. Through integrated design, optimized conveyor belt material, and unique structural design, this utility model not only solves the problems of separation of steaming and drying processes, sticking and deformation of rice noodle sheets, and insufficient performance of conveyor belts in existing rice noodle processing equipment, but also significantly improves production efficiency and rice noodle sheet quality, and has high practical value and market application prospects.

[0029] 7. This utility model effectively prevents the conveyor belt from shifting laterally. It uses support columns to limit and block the lateral movement of the conveyor belt. The width of the conveyor belt channel (i.e., the length of the idler rollers) is the same as or approximately the same as the width of the conveyor belt, leaving no room for deviation. When the conveyor belt tends to shift laterally, it will contact the support column, which then limits and blocks its movement, preventing lateral shifting and rotational deviation. Furthermore, the outer wall of the support column is curved (i.e., the support column is cylindrical), preventing scratches on the conveyor belt edges when the belt contacts it.

[0030] 8. The steamed rice noodles must pass through a scraper to reduce breakage and remove sticky residue. Existing rice noodle steamers have a single driving roller at the head and a single driven roller at the tail, resulting in a large bending rate of the rice cloth, making the rice noodle sheets prone to detaching and breaking under gravity. In this technical solution, the steamer head has an additional roller. The two rollers are vertically aligned, reducing the bending rate of the rice cloth, which allows the scraper to move forward more easily. This reduces the impact of gravity on the rice noodle sheets, allowing them to reach the scraper directly. The scraper then removes the rice noodle sheets without breaking them. The rice noodle sheets are constantly in contact with the scraper, continuously carrying away the sticky residue on the scraper, preventing residue buildup and eliminating sticky residue.

[0031] 9. During drying, the rice sheet separates smoothly from the conveyor belt. In existing technologies, the rice sheet separates from the conveyor belt by naturally falling due to gravity. Rice sheets with higher viscosity or moisture content will affect the separation, causing the rice sheet to scrape or roll together with the rollers. In this technical solution, by using rollers to support the conveyor belt, the distance between the conveyor belts in two adjacent conveyor components is reduced. This prevents the rice sheet from detaching from the upper conveyor belt by gravity. Instead, the lower conveyor belt pulls and pulls the rice sheet, preventing it from breaking and allowing the rice sheet to separate smoothly from the upper conveyor belt.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0049] Please see Figures 1 to 13 The present invention provides a technical solution: a Teflon mesh conveyor belt pre-drying steaming powder integrated machine, including a support frame 1, a top cover 2, a rice noodle steaming box 3, a conveying component, and auxiliary components. The support frame 1 is a rectangular frame structure. The top cover 2 is fixedly installed on the top of the support frame 1. A rice noodle inlet 22 is opened on the top cover 2. The rice noodle steaming box 3 is fixedly installed on the top cover 2.

[0050] The steaming box 3 for rice noodles includes, but is not limited to, the steaming box described in Chinese patent application CN207305999U, and may also use other existing steaming boxes on the market. The steaming box 3 is used to steam the rice noodles. It is equipped with steam pipes and temperature sensors to precisely control the steaming temperature and time, ensuring the quality of the steamed rice noodles. The support frame 1 serves as the main frame of the entire equipment, supporting and fixing other components to ensure the overall stability and structural strength of the equipment. The top cover 2 is fixedly installed above the support frame 1, protecting the internal components of the support frame 1 and also supporting and fixing the steaming box 3. The conveying components are used to transport the steamed rice noodles. Auxiliary components are used to dry the rice noodles during the conveying process.

[0051] The conveying components include a drive assembly and multiple conveying assemblies, each of which is installed within the support frame 1 and arranged sequentially from top to bottom. Specifically, the conveying assemblies on odd-numbered layers are vertically aligned, while those on even-numbered layers are vertically aligned, with the conveying assemblies on odd-numbered layers offset from those on even-numbered layers.

[0052] The drive assembly is used to drive each conveying assembly. The arrangement of the conveying assemblies facilitates the sequential and coordinated conveying of the powder sheet, allowing it to move from top to bottom through each assembly. Each conveying assembly includes a second drive roller 9, which is rotatably mounted on the support frame 1. The drive assembly is connected to the second drive roller 9 in each conveying assembly. The drive assembly drives the second drive roller 9 in the odd-numbered layers to rotate clockwise, and drives the second drive roller 9 in the even-numbered layers to rotate counterclockwise. Specifically, the conveying assembly also includes a second driven roller 10 and a conveyor belt 11. The second driven roller 10 is rotatably mounted on the support frame 1, and the second drive roller 9 and the second driven roller 10 are laterally aligned and parallel to each other. The conveyor belt 11 surrounds the outer walls of the second drive roller 9 and the second driven roller 10, and the second drive roller 9 is connected to the second driven roller 10 via the conveyor belt 11.

[0053] The second drive roller 9 rotates, driving the conveyor belt 11 to move and thus conveying the rice noodle sheets. In the conveying assembly located on the odd-numbered layers, the second drive roller 9 rotates clockwise, causing the conveyor belt 11 to rotate and move clockwise. The conveyor belt 11 then moves the rice noodle sheets to the right (see reference). Figure 2 After the powder sheet moves to the right, it falls onto the conveyor belt 11 of the even-numbered layer conveyor assembly; the second drive roller 9 in the even-numbered layer conveyor assembly rotates counterclockwise, driving the conveyor belt 11 to rotate and move counterclockwise, and the conveyor belt 11 drives the powder sheet to move to the left (see reference). Figure 2This process is repeated, allowing the rice paper to be conveyed sequentially between multiple conveyor belts 11, increasing the conveying distance and drying time of the rice paper, and improving the drying effect.

[0054] The auxiliary components include at least two idler roller assemblies and multiple stainless steel pipe rows 15. Each idler roller assembly is fixedly installed within the support frame 1, and the idler roller assemblies are arranged laterally in sequence. Each stainless steel pipe row 15 is located within a respective conveying assembly, and the stainless steel pipe rows 15 are arranged longitudinally in sequence, with the ends of the stainless steel pipe rows 15 fixedly installed to the idler roller assemblies.

[0055] The idler roller assembly supports the conveyor belts 11 in each conveying assembly and limits and blocks the conveyor belts 11 in each conveying assembly. Each stainless steel pipe row 15 is used to dry the powder sheet on each conveyor belt 11.

[0056] More specifically, the idler assembly includes two support columns 13, two connecting beams 25, and multiple idlers 14. The upper and lower ends of the support columns 13 are fixedly connected to the two connecting beams 25, respectively. The two support columns 13 and the two connecting beams 25 together form a U-shaped frame structure. The two support columns 13 are horizontally parallel, and the outer walls of the support columns 13 are curved. The two support columns 13 are located on both sides of the conveyor belt 11 in each conveying assembly. The lateral edges of the two support columns 13 abut against the conveyor belt 11, and the two support columns 13 provide lateral limiting and blocking for the conveyor belt 11. The width of the conveyor belt 11 is equal to the length of the idlers 14.

[0057] The connecting beam 25 supports and fixes the two support columns 13. The two support columns 13 hold the sides of the conveyor belt 11, that is, they limit and block the side edges of the conveyor belt 11 to prevent it from deviating. The width of the conveyor belt channel (i.e., the length of the idler rollers 14) is the same as the width of the conveyor belt 11 (in actual implementation, it is normal for the width of the conveyor belt 11 to be a few centimeters smaller than the idler rollers 14), leaving no room for the conveyor belt 11 to move. When the conveyor belt 11 tends to move laterally, it will touch the support columns 13, which will then limit and block the conveyor belt 11 laterally, preventing it from deviating during rotation. Simultaneously, the outer wall of the support column 13 is curved (i.e., the support column 13 is cylindrical), which prevents the support column 13 from scratching the edges of the conveyor belt 11 when it comes into contact with it.

[0058] More specifically, each idler roller 14 is arranged longitudinally, and its two ends are rotatably connected to two support columns 13 (or fixedly connected, depending on the actual implementation). Each idler roller 14 is respectively installed below the conveyor belt 11 in each conveying assembly, and the idler roller 14 abuts against the lower surface of the conveyor belt 11. The idler roller 14 supports and lifts the conveyor belt 11, bringing the conveyor belts 11 in two adjacent conveying assemblies closer together. A powder sheet sandwich layer 26 is formed between the conveyor belts 11 in two adjacent conveying assemblies, and the powder sheet is located in the powder sheet sandwich layer 26 and moves under the drive of the lower conveyor belt 11.

[0059] In this technical solution, by using idler rollers 14 to support the conveyor belt 11, the distance between the conveyor belts 11 in two adjacent conveying components is reduced, preventing the rice noodle sheet from detaching from the upper conveyor belt 11 by gravity. Instead, the rice noodle sheet is pulled and tugged by the lower conveyor belt 11, allowing it to slowly transition from the upper conveyor belt 11 to the lower conveyor belt 11. This prevents the rice noodle sheet from breaking when it falls due to gravity, and allows it to separate smoothly from the upper conveyor belt 11.

[0060] More specifically, the stainless steel pipe array 15 includes two square tubes 1502 and multiple steel pipes 1501. The two ends of the square tubes 1502 are fixedly connected to two support columns 13 in the idler roller assembly. The steel pipes 1501 are arranged sequentially and parallel to each other, with both ends of each steel pipe 1501 fixedly installed to the two square tubes 1502, and the interiors of the steel pipes 1501 and square tubes 1502 are interconnected. A steam inlet pipe 1503 is fixedly installed on one square tube 1502 and the two are connected; a steam outlet pipe 1504 is fixedly installed on the other square tube 1502 and the two are connected. Multiple fans 16 are fixedly installed above the stainless steel pipe array 15.

[0061] The stainless steel pipe array 15 serves two purposes: first, to support and fix the various fans 16; and second, to allow steam to flow through it, heating the stainless steel pipe array 15 and the adjacent area. The fans 16 blow hot air near the stainless steel pipe array 15, drying the powder sheet. The steam inlet pipe 1503 allows steam to flow into the square pipe 1502, and then into the various steel pipes 1501. The steam outlet pipe 1504 discharges the steam or liquid from the square pipe 1502 and the steel pipes 1501.

[0062] Specifically, the drive assembly includes a motor 4, a reducer 5, and a first chain 6. The motor 4 and reducer 5 are both fixedly mounted on the top cover 2. The output shaft end of the motor 4 is fixedly mounted to the power input shaft end of the reducer 5, and a third sprocket is fixedly mounted on the power output shaft end of the reducer 5. A second sprocket 17 is fixedly fitted onto the outer wall of one end of the shaft of the second drive roller 9. The first chain 6 is wound around the third sprocket and the second sprockets 17 on each of the second drive rollers 9, and the first chain 6 meshes with the third sprocket and each of the second sprockets 17 respectively.

[0063] The drive assembly provides power to the conveying assembly. The motor 4 is reduced in speed by the reducer 5, which drives the third sprocket to rotate. The third sprocket drives the first chain 6 to rotate, which in turn drives the second sprockets 17 on each of the second drive rollers 9 to rotate. The second sprockets 17 drive the second drive rollers 9 to rotate, and the second drive rollers 9 drive the conveyor belt 11 to rotate.

[0064] More specifically, a powder cloth assembly is installed on the rice noodle steamer 3. The powder cloth assembly includes a first driving roller 7, a fourth driving roller 24, a first driven roller 20, and a powder cloth 21. The first driving roller 7 and the fourth driving roller 24 are rotatably mounted on one side wall of the rice noodle steamer 3 near the rice noodle inlet 22, and are arranged longitudinally. The first driven roller 20 is rotatably mounted on the other side wall of the rice noodle steamer 3. The powder cloth 21 penetrates the rice noodle steamer 3 and is wrapped around the outer walls of the first driving roller 7, the fourth driving roller 24, and the first driven roller 20. The first driving roller 7 and the fourth driving roller 24 are connected to the first driven roller 20 via the powder cloth 21. The first driving roller 7 and the fourth driving roller 24 rotate synchronously.

[0065] When the first active roller 7 and the fourth active roller 24 rotate synchronously, they drive the first driven roller 20 to rotate via the powder cloth 21. During the rotation, the powder cloth 21 moves the rice noodle raw material through the rice noodle steaming box 3. After steaming, the rice noodle raw material becomes rice noodle sheets. At the same time, the powder cloth 21 removes the steamed rice noodle sheets from the rice noodle steaming box 3.

[0066] At least four first horizontal supports 18 are fixedly installed on one side wall of the rice noodle steamer 3, and multiple second horizontal supports 19 are fixedly installed on the other side wall of the rice noodle steamer 3. A first active roller 7 is rotatably mounted on two of the first horizontal supports 18, and a fourth active roller 24 is rotatably mounted on the other two first horizontal supports 18. A first driven roller 20 is rotatably mounted on two of the second horizontal supports 19. A scraper 8 is fixedly mounted on the first horizontal support 18, and the scraper 8 is inclined, with its upper edge abutting against the side wall of the rice noodle cloth 21 near the rice noodle inlet 22. A third active roller 23 is rotatably mounted on the top cover 2 at the rice noodle inlet 22, and is located below the scraper 8. A motor 4 is connected to the first active roller 7, the third active roller 23, and the fourth active roller 24 respectively, and the motor 4 drives the first active roller 7, the third active roller 23, and the fourth active roller 24 to rotate counterclockwise.

[0067] The third drive roller 23 supports the powder sheet, ensuring its smooth descent and preventing breakage due to gravity or other factors. The motor 4 drives the first drive roller 7, the third drive roller 23, and the fourth drive roller 24. The transmission connection between the motor 4 and the first drive roller 7 (and the fourth drive roller 24) includes, but is not limited to, chain drive; the transmission connection between the motor 4 and the third drive roller 23 also includes, but is not limited to, chain drive. The scraper 8, also known as a scraper blade, scrapes the powder sheet off the powder cloth 21 with its upper edge, preventing it from sticking. After falling, the powder sheet slides down along the scraper 8 and lands on the third drive roller 23. After passing through the powder sheet inlet 22, it lands on the conveyor belt 11 of the uppermost conveyor assembly.

[0068] Specifically, the conveyor belt 11 is a Teflon mesh conveyor belt. Multiple side baffles 12 are hinged to the side wall of the support frame 1 along its length and height.

[0069] The side baffles 12 are used to block the sides (length and height sides) of the support frame 1, improving the shielding and protection of the inside of the support frame 1, preventing external contamination of the rice noodle sheets, and making the rice noodle sheet production process more hygienic. At the same time, the side baffles 12 are installed on the support frame 1 by hinges, which makes them easy to open, convenient to observe the inside of the support frame 1, and convenient to clean the inside of the support frame 1, thus improving production hygiene.
