[0005] To achieve the above objectives, this utility model provides the following technical solution: a drying device for crispy noodles, comprising a drying chamber and a conveyor belt. The conveyor belt runs through both ends of the drying chamber and has evenly distributed air vents. An air vent block is located in the middle of the top of the drying chamber, and a hot air blower is located on one side of the top of the drying chamber. The output block of the hot air blower extends into the air vent block. Connecting plates are located in the middle of the inner walls at both ends of the drying chamber below the conveyor belt, and a heating plate is located between the connecting plates. Heating tubes are evenly distributed within the heating plate. One end of each heating tube extends into the connecting plate and is fixedly connected to an air vent pipe. The other end of the air vent pipe extends to the outside of the drying chamber and is connected to the hot air blower. A horizontal lead screw is located in the middle of the drying chamber below the heating tube, via a bearing seat. A threaded block is threaded onto the lead screw. The top of the threaded block has a cleaning block with a diameter larger than that of the heating plate, and the bottom of the threaded block, away from the hot air blower, has a scraper. The bottom of the scraper is in contact with the bottom of the drying chamber, allowing the heating tube to heat the heating plate. This allows the hot air generated by the heating plate and the hot air delivered by the air outlet block to heat the top and bottom of the dried noodles, making the heating and drying more uniform, thereby improving the drying speed and the crispness of the noodles. After the work is completed, the threaded block can move the top cleaning block and the bottom scraper simultaneously, reducing the adhesion of waste materials, which would affect the subsequent heating and drying effect, and reducing waste.

[0011] Preferably, a motor is provided at the end of the drying box near the filter box, corresponding to the position of the lead screw, and the output end of the motor is connected to the lead screw through a bearing and a coupling.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The drying device for crispy noodles uses a filter box to adsorb and filter hot air, which then enters the heating tube through the air inlet pipe. This allows the heating tube to heat the heating plate, and the hot air generated can be used to heat and dry the bottom of the crispy noodles through the air outlet on the conveyor belt. At the same time, the air outlet block can continuously deliver hot air to heat the top of the noodles, making the heating and drying more uniform, thereby improving the drying speed and crispiness of the noodles. After the operation is completed, the motor can drive the threaded block on the lead screw to move, which in turn moves the cleaning block on top. When the cleaning block moves, it can drive the brush bristles to clean the top of the connecting plate and the heating plate, and when it is not moving, it can clean the bottom of the conveyor belt, reducing the adhesion of waste material and affecting the subsequent heating and drying effect. At the same time, the scraper at the bottom of the threaded block can scrape the waste material to one place for easy collection later. Attached Figure Description

[0022] When in use, the hot air blower 6 can send hot air into the air outlet block 14, and the air outlet block 14 can send hot air to the crispy surface for heating and drying. During drying, the hot air passes through the crispy surface and the conveyor belt 2, and only a small amount of hot air is sent to the bottom of the conveyor belt 2 to heat the area below it.

[0023] A connecting plate 17 is provided at the middle position of the inner wall of both ends of the drying box 1 below the conveyor belt 2, and a heating plate 12 is provided between the connecting plates 17. Heating pipes 18 are evenly laid in the heating plate 12. One end of the heating pipe 18 extends into the connecting plate 17 and is fixedly connected to the air outlet pipe 7. The other end of the air outlet pipe 7 extends to the outside of the drying box 1 and is connected to the hot air blower 6. The other end of the heating pipe 18 extends into the connecting plate 17 on the other side and is fixedly connected to the air inlet pipe 13. The other end of the air inlet pipe 13 passes through the drying box 1 and is connected to the bottom of the filter box 3.

[0024] In use, the hot air filtered and adsorbed in the filter box 3 can enter the heating tube 18 through the air inlet pipe 13, which can heat the heating plate 12. The hot air generated by heating can heat and dry the bottom of the crispy noodles through the air outlet on the conveyor belt 2, which can make the heating and drying more uniform, thereby improving the drying speed and crispiness of the crispy noodles. The hot air in the heating tube 18 can be re-entered into the hot air blower 6 through the air outlet pipe 7 connected to the other end, which can save heating time.

[0025] A horizontal lead screw 11 is provided in the middle of the drying box 1 below the heating tube 18 via a bearing seat, and a threaded block 9 is connected to the lead screw 11 by a thread. The top of the threaded block 9 is provided with a cleaning block 10 with a diameter larger than that of the heating plate 12. A through slot is provided in the middle of the cleaning block 10, and bristles are provided on the top of both the outer and inner sides of the cleaning block 10. The bristles on the outer and inner sides of the cleaning block 10 are respectively attached to the conveyor belt 2 and the connecting plate 17. A scraper 8 is provided on the side of the bottom of the threaded block 9 away from the hot air blower 6, and the bottom of the scraper 8 is attached to the bottom of the drying box 1. A motor 4 is provided at the end of the drying box 1 near the filter box 3 corresponding to the position of the lead screw 11, and the output end of the motor 4 is connected to the lead screw 11 via a bearing and a coupling.

[0026] When in use, the motor 4 can be started to drive the threaded block 9 on the lead screw 11 to move, which can drive the top cleaning block 10 to move. When the cleaning block 10 moves, it can drive the bristles to clean the top of the connecting plate 17 and the heating plate 12, and clean the bottom of the conveyor belt 2 when it is not moving. This can reduce the adhesion of waste materials and affect the subsequent heating and drying effect. At the same time, the scraper 8 at the bottom of the threaded block 9 can scrape the waste materials to one place for easy collection later.

[0027] A filter box 3 is provided on the top of the drying oven 1 at the end away from the air outlet pipe 7, and a sealing door is hinged on the side of the filter box 3. A connecting pipe 15 is provided on the top of one side of the filter box 3, extending into the drying oven 1. A sliding groove 20 is provided on the inner wall of both sides in the middle of the filter box 3, and a desiccant 21 and activated carbon 22 are slidably connected between the sliding grooves 20.

[0028] During use, the hot air in the drying oven 1 can enter the filter box 3 through the connecting pipe 15. After entering the filter box 3, the hot air is adsorbed and dried by the desiccant 21 and activated carbon 22, which can prevent the steam and waste residue in the hot air from entering the heating tube 18 and affecting the heating effect. Then, the sealing door can be opened periodically to slide the desiccant 21 and activated carbon 22 in the filter box 3 out from the slide groove 20 for easy replacement.

[0029] A collection trough is provided at the bottom of the drying oven 1, away from the filter box 3, and a collection frame 5 is connected to the bottom of the drying oven 1 at the position corresponding to the collection trough by fixing bolts;

[0030] When in use, the scraper 8 can scrape the dried noodle waste into the collection trough and drop it into the collection box 5, which makes it convenient for staff to collect the waste in the collection box 5 after work and can reduce waste.

[0031] The cleaning block 10 has a slider 19 at the middle position of both ends, and the side wall of the drying box 1 corresponding to the slider 19 has a groove 16, and the slider 19 is slidably connected in the groove 16.

[0032] In use, the cleaning block 10 can drive the sliders 19 at both ends to move within the slide groove 16, which can make the movement of the cleaning block 10 more stable.

[0033] In this embodiment, hot air is sent into the air outlet block 14 by starting the hot air blower 6. When the internal temperature is suitable for drying, the conveyor belt 2 can transport the dried crispy noodles into the drying chamber 1 for drying and then to the next process. The air outlet block 14 then sends hot air onto the crispy noodles for heating and drying. During drying, the hot air passes through the crispy noodles and the conveyor belt 2, with only a small amount reaching below the conveyor belt 2 for heating. A portion of the hot air then enters the filter box 3 through the connecting pipe 15. Inside the filter box 3, the hot air is adsorbed and dried by the desiccant 21 and activated carbon 22, preventing steam and waste from entering the heating tube 18 and affecting the heating effect. The heating tube 18 then heats the heating plate 12, allowing the generated hot air to heat and dry the bottom of the crispy noodles through the air outlet on the conveyor belt 2, resulting in more uniform heating and drying, thus improving the drying speed and crispness of the noodles. The hot air in the heating tube 18 can be re-entered into the hot air blower 6 through the exhaust pipe 7 connected to the other end, which can save heating time. After the work is completed, the motor 4 can drive the threaded block 9 on the lead screw 11 to move, which can drive the top cleaning block 10 to move. When it moves, it can drive the sliders 19 at both ends to move in the first slide groove 16, which can make the movement of the cleaning block 10 more stable. Then, when the cleaning block 10 moves, it can drive the brush bristles to clean the top of the connecting plate 17 and the heating plate 12, and clean the bottom of the conveyor belt 2 when it is not moving, which can reduce the adhesion of waste material and affect its subsequent heating and drying effect. At the same time, the scraper 8 at the bottom of the threaded block 9 can scrape the waste material to the collection trough and drop it into the collection frame 5, which is convenient for the staff to collect the waste material in the collection frame 5 after the work is completed, which can reduce waste. Then, the sealing door can be opened periodically as required to slide the desiccant 21 and activated carbon 22 in the filter box 3 out from the second slide groove 20 for easy replacement.
