Description

Technical Field

[0001] This utility model relates to the field of rice noodle processing technology, and in particular to a sieving device for rice noodle processing. Background Technology

[0002] Rice noodles, a traditional Chinese snack, are a very popular food in southern China. Rice noodles are made from rice, processed through soaking, steaming, and pressing into strips or strands. During processing, depending on the desired effect, the rice is often ground into rice noodles of different particle sizes and then sieved to obtain the raw material for the final product.

[0003] However, the current rice noodle processing crushing and filtering devices on the market screen the rice noodles by particle size after crushing. Since most existing rice noodle screening devices directly screen the crushed rice noodles by pouring them out, the rice noodles often accumulate during the screening process, resulting in insufficient screening. Therefore, this application provides a rice noodle processing screening device to meet the needs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where rice noodles cannot be adequately screened, and to propose a screening device for rice noodle processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sieving device for rice noodle processing, comprising a drying box and a sieving unit, further comprising a crushing unit and a conveying unit; a sliding plate is fixedly connected to the upper and lower parts of the front inner wall of the drying box, a sliding plate is fixedly connected to the middle inner wall of the rear end of the drying box, a resistance heating wire is provided at the bottom of both the sliding plate and the sliding plate, a guide plate is fixedly connected to the lower inner wall of the rear end of the drying box, and a hot air box is fixedly connected to the upper and lower parts of the front end of the drying box. A second hot air box is fixedly connected to the middle of the rear end of the unit. The rice noodles are dried and transported by the sliding heating of sliding plates one and two, and by the blowing heating of hot air boxes one and two, thus extending the storage time of the rice noodles. The screening unit is used to shake and screen the heated and transported rice noodles. The crushing unit is used to crush the rice noodle raw materials to reduce the particle size. The conveying unit is used to transport the screened rice noodles for storage and use. The drying box, the screening unit, the crushing unit, and the conveying unit are all connected to the drying box.

[0006] Through the above technical solution, rice noodles are fed into the drying box and sequentially slide down through the upper sliding plate 1, the middle sliding plate 2, and the lower sliding plate 1 in a stepped conveying process. During the conveying stage, resistance heating wires heat the sliding plate 2 and the sliding plate 1, so that the rice noodles sliding down the sliding plate 2 and the sliding plate 1 are heated and dried. At the same time, the heating is diffused through the hot air box 1 and the hot air box 2, which further improves the drying effect of the rice noodles.

[0007] Furthermore, the screening unit includes a discharge port fixedly connected to the bottom of the drying chamber. A servo motor is fixedly connected to the middle of one side of the discharge port. The output end of the servo motor passes through one side of the discharge port and is fixedly connected to one end of a drive rod. The rear of the drive rod is fixedly connected to one end of a central drive column. The other end of the central drive column is fixedly connected to the front of a second drive rod. The rear end of the second drive rod is rotatably connected to the inner wall of the other side of the discharge port. A movable block is rotatably connected to the middle of the central drive column. The other end of the movable block is rotatably connected to the bottom of a locking column. The top of the locking column is fixedly connected to the middle of the bottom of the screening plate. Positioning columns are fixedly connected to the middle of both the front and rear sides of the bottom of the screening plate. The bottom ends of the positioning columns are fixedly connected to the top of a hollow column via springs. The hollow column is fixedly connected to the top of a mounting block.

[0008] Through the above technical solution, a servo motor drives drive rod one, the central drive column, and drive rod two to rotate. The rotation of the central drive column then drives the movable block to move. The movement of the movable block causes the locking column to move intermittently upward, thereby causing the screening plate to start sieving up and down, vibrating and screening the rice flour on it. At the same time, the positioning columns, springs, and hollow columns set on the front and rear sides of the bottom of the screening plate also ensure the overall stability of the screening plate during vibration. In addition, due to the overall design of the feed port, the bottom is trapezoidal in shape, which also plays a certain limiting role when the screening plate vibrates up and down, improving the stability of the screening plate.

[0009] Furthermore, inclined drop plates are fixedly connected to the lower inner walls of the front and rear sides of the discharge port, and mounting blocks are fixedly connected to the top center of the inclined drop plates. A drive rod one is rotatably connected to the center of the front mounting block, and a drive rod two is rotatably connected to the center of the rear mounting block.

[0010] The above technical solution allows for better fixation of the positions of drive rod one and drive rod two using mounting blocks, while the inclined drop plate allows for better descent of the screened material.

[0011] Furthermore, the pulverizing unit includes a pulverizing box fixedly connected to the top of the drying oven. Pulverizing rollers are rotatably connected to the left and right sides of the interior of the pulverizing box. A protective shell is fixedly connected to the outer side of the pulverizing box. A drive motor is fixedly connected to the outer side of the protective shell. The output end of the drive motor passes through the protective shell and is connected to one end of gear one. Gear two is meshed with one side of gear one. The inner sides of gear one and gear two are fixedly connected to one end of the pulverizing rollers.

[0012] The above technical solution utilizes a drive motor to rotate gear one, which in turn drives gear two to rotate, thereby driving the respective connected crushing rollers to rotate, thus achieving the crushing process of rice noodles.

[0013] Furthermore, the conveying unit includes a auger conveyor fixedly connected to the bottom of the discharge port, and the discharge port of the auger conveyor is provided with a receiving trolley.

[0014] The above technical solution utilizes a auger conveyor and a receiving trolley to pick up the dried rice noodles and then transfer or package them.

[0015] Furthermore, both the first and second hot air boxes are fixedly connected to an isolation mesh plate on their inward side.

[0016] The above technical solution prevents rice noodles from entering hot air box 1 and hot air box 2 through the isolation mesh plate 1, ensuring their normal operation.

[0017] Furthermore, exhaust fan boxes are fixedly connected to the upper and lower parts of the left and right sides of the drying oven, and an isolation mesh plate is provided on the inward side of each exhaust fan box.

[0018] The above technical solution utilizes an exhaust fan to remove hot air from the drying chamber, preventing excessive heat inside the drying chamber from causing overheating of the rice noodles during drying.

[0019] This utility model has the following beneficial effects:

[0020] In this invention, rice noodles are fed into a drying chamber and sequentially slide down through an upper sliding plate, a middle sliding plate, and a lower sliding plate in a stepped manner. During the conveying stage, resistance heating wires heat the sliding plates to dry the rice noodles. Simultaneously, the rice noodles are heated and diffused through hot air boxes to further improve the drying effect.

[0021] In this invention, a servo motor drives drive rod one, drive column two, and drive rod two to rotate. The rotation of the drive column then drives the movable block to move. The movement of the movable block causes the locking column to move intermittently upward, thereby causing the screening plate to start sieving up and down, vibrating and screening the rice flour on it. At the same time, the positioning columns, springs, and hollow columns set on the front and rear sides of the bottom of the screening plate also ensure the overall stability of the screening plate during vibration. In addition, due to the overall design of the feed port, the bottom is trapezoidal, and its shape also plays a certain limiting role when the screening plate vibrates up and down, improving the stability of the screening plate and the effect of thorough screening.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1-5 This utility model provides an embodiment of a rice noodle processing sieving device, including a drying box 1 and a sieving unit 2, as well as a crushing unit 3 and a conveying unit 4; a sliding plate 5 is fixedly connected to the upper and lower parts of the front inner wall of the drying box 1, a sliding plate 6 is fixedly connected to the middle inner wall of the rear end of the drying box 1, and resistance heating wires 7 are provided at the bottom ends of both sliding plates 5 and 6; a guide plate 8 is fixedly connected to the lower inner wall of the rear end of the drying box 1; a hot air box 9 is fixedly connected to the upper and lower parts of the front end of the drying box 1; and the rear end of the drying box 1... A hot air box 210 is fixedly connected to the middle of the unit. The rice noodles are dried and transported by the sliding heating of the sliding plates 15 and 26, and the blowing heating of the hot air boxes 19 and 210, thus extending the storage time of the rice noodles. The screening unit 2 is used to shake and screen the heated and transported rice noodles. The crushing unit 3 is used to crush the rice noodle raw materials to reduce the particle size. The conveying unit 4 is used to convey the screened rice noodles for storage and use. The drying box 1, screening unit 2, crushing unit 3 and conveying unit 4 are all connected to the drying box 1. Rice noodles are fed into drying chamber 1 and are conveyed in a stepped manner by sliding through the upper sliding plate 5, the middle sliding plate 6, and the lower sliding plate 5. During the conveying stage, resistance heating wire 7 heats the sliding plate 6 and sliding plate 5, so that the rice noodles sliding on the sliding plate 6 and sliding plate 5 are heated and dried. At the same time, the rice noodles are heated and diffused through hot air box 9 and hot air box 10 to further improve the drying effect of the rice noodles.

[0032] Both hot air boxes 1-9 and 2-10 are fixedly connected to an isolation mesh plate 11 on their inner side. The isolation mesh plate 11 prevents rice flour from entering hot air boxes 1-9 and 2-10, ensuring their normal operation.

[0033] The left and right sides and the upper and lower parts of the drying oven 1 are all fixedly connected to exhaust fan boxes 12, and the inner side of each exhaust fan box 12 is provided with an isolation mesh plate 13. The exhaust fan boxes 12 are used to extract the hot air inside the drying oven 1 to prevent the internal temperature of the drying oven 1 from becoming too high and causing the rice noodles to be overheated during drying.

[0034] As one implementation method in this embodiment, such as Figure 5As shown, the screening unit 2 includes a discharge port 201 fixedly connected to the bottom of the drying chamber 1. A servo motor 202 is fixedly connected to the middle of one side of the discharge port 201.

The other end of the movable block 206 is rotatably connected to the bottom end of the locking column 207. The top end of the locking column 207 is fixedly connected to the middle of the bottom end of the screening plate 208. Positioning columns 209 are fixedly connected to the middle of the front and rear sides of the bottom end of the screening plate 208. The bottom ends of the positioning columns 209 are fixedly connected to the top end of the hollow column 211 through the spring 210. The hollow column 211 is fixedly connected to the top end of the mounting block 212. The servo motor 202 drives the drive rod 203, the central drive column 204, and the second drive rod 205 to rotate. The rotation of the central drive column 204 then drives the movable block 206 to move. The movement of the movable block 206 causes the locking column 207 to move intermittently upward, thereby causing the screening plate 208 to start sieving up and down, vibrating and screening the rice flour on it. At the same time, the positioning columns 209, springs 210, and hollow columns 211 set on the front and rear sides of the bottom of the screening plate 208 also ensure the overall stability of the screening plate 208 during vibration. In addition, due to the overall design of the feed port 201, the bottom is trapezoidal, and its shape also plays a certain limiting role when the screening plate 208 vibrates up and down, improving the stability of the screening plate 208.

[0035] Inclined drop plates 213 are fixedly connected to the lower inner walls of the front and rear sides of the discharge port 201. Mounting blocks 212 are fixedly connected to the top center of each inclined drop plate 213. A drive rod 203 is rotatably connected to the center of the front mounting block 212, and a drive rod 205 is rotatably connected to the center of the rear mounting block 212. The mounting blocks 212 better fix the positions of the drive rods 203 and 205, while the inclined drop plates 213 allow for better descent of the screened material.

[0036] As one implementation method in this embodiment, such as Figure 3As shown, the pulverizing unit 3 includes a pulverizing box 301 fixedly connected to the top of the drying chamber 1. Pulverizing rollers 302 are rotatably connected to both the left and right sides of the interior of the pulverizing box 301. A protective shell 303 is fixedly connected to the outward side of the pulverizing box 301. A drive motor 304 is fixedly connected to the outside of the protective shell 303. The output end of the drive motor 304 passes through the protective shell 303 and is connected to one end of a gear 305. A gear 306 is meshed with one side of the gear 305. The inner sides of both gears 305 and 306 are fixedly connected to one end of the pulverizing rollers 302. The drive motor 304 drives gear 305 to rotate, which in turn drives the meshing gear 306 to rotate, thereby driving the respective connected pulverizing rollers 302 to rotate, thus achieving the pulverization of rice flour.

[0037] As one implementation method in this embodiment, such as Figure 2 As shown, the conveying unit 4 includes a auger conveyor 401 fixedly connected to the bottom of the discharge port 201, and a receiving trolley 402 is provided at the discharge port of the auger conveyor 401. The auger conveyor 401 and the receiving trolley 402 are used to collect the dried rice noodles for subsequent transfer or packaging.

[0038] Working Principle: During operation, rice noodles are fed into the drying chamber 1 and sequentially slide down through the upper sliding plate 5, the middle sliding plate 6, and the lower sliding plate 5 in a stepped conveying process. During this conveying stage, the resistance heating wire 7 heats the sliding plates 6 and 5, thus drying the rice noodles that slide down them. Simultaneously, the heat is diffused through the hot air boxes 9 and 10, further improving the drying effect. Meanwhile, the servo motor 202 drives the drive rod 203, the central drive column 204, and the second drive rod 205 to rotate. The rotation then drives the movable block 206 to move. The movement of the movable block 206 causes the locking column 207 to move upward intermittently, thereby causing the screening plate 208 to start sieving up and down, vibrating and screening the rice noodles on it. At the same time, the positioning column 209, spring 210 and hollow column 211 set on the front and rear sides of the bottom of the screening plate 208 also ensure the overall stability of the screening plate 208 during vibration. In addition, due to the overall design of the feed port 201, which is trapezoidal at the bottom, its shape also plays a certain limiting role when the screening plate 208 vibrates up and down, improving the stability of the screening plate 208 and the screening effect of the rice noodles.
