Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of drying equipment, and in particular relates to a drying device for corn flour processing. Background Technology
[0002] During the processing of corn flour, a certain amount of moisture is introduced. If not dried, this moisture will provide conditions for the growth of microorganisms, causing the corn flour to spoil. At the same time, high moisture content will also make the corn flour prone to clumping during storage, affecting subsequent processing and use. Drying can reduce the moisture content of corn flour, effectively inhibit the reproduction of microorganisms, extend the shelf life, and improve its fluidity, making it easier to handle during storage, transportation and processing, and ensuring the stability of product quality.
[0003] However, existing corn flour drying equipment tends to cause corn flour to clump after drying, which damages its particle state, affects its appearance and taste, makes it difficult to disperse evenly in food processing, and leads to a decline in product quality.
[0004] To address these issues, we provide a drying apparatus for corn flour processing. Utility Model Content
[0005] The purpose of this invention is to provide a drying device for corn flour processing. By rotating the auger rod, the extension shaft is driven to rotate, which in turn drives the crushing shaft to rotate, so that the crushing blades outside the crushing shaft can crush the corn flour, thus solving the problem of corn flour easily clumping after drying.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model is a drying device for corn flour processing, including a base frame; a drying chamber is fixedly provided on the top of the base frame, and a heating tube assembly for heating the air inside the drying chamber and a conveying assembly for conveying corn flour are provided at the bottom of the inner cavity of the drying chamber; a crushing assembly for breaking up corn flour is provided on one side of the base frame.
[0008] The material conveying assembly includes three conveying cylinders that are equidistantly arranged and fixed inside the drying chamber. Each of the three conveying cylinders is rotatably connected to an auger rod. A first transmission assembly is provided at the end of each of the three conveying cylinders near the input end. A feeding hopper that communicates with each of the three conveying cylinders is fixed at the input end of each of the three conveying cylinders. A discharge hopper that communicates with each of the three conveying cylinders is fixed at the output end of each of the three conveying cylinders. A drive motor is fixed at the end of one of the conveying cylinders near the discharge hopper, and the corresponding auger rod is fixed at the output end of the drive motor.
[0009] The crushing assembly includes a crushing barrel fixed to one end of the base frame near the drive motor, and a discharge hopper connected to the crushing barrel. A crushing shaft is rotatably connected inside the crushing barrel. Multiple crushing blades are fixed to the outer part of the crushing shaft located in the crushing barrel. A driven bevel gear is fixed to the top of the crushing shaft. A second transmission assembly for driving the crushing shaft to rotate is provided on the top of the crushing barrel.
[0010] The present invention is further configured such that an air outlet and an air inlet are respectively provided at the top and bottom of the drying chamber, a filter screen covering the bottom of the air inlet is fixedly connected to the bottom of the drying chamber, and an exhaust fan is installed inside the air outlet.
[0011] The present invention is further configured such that the heating tube assembly includes an inlet pipe and an outlet pipe fixedly connected to both sides inside the drying chamber, and multiple equally spaced thin branch pipes are connected between the inlet pipe and the outlet pipe.
[0012] The present invention is further configured such that multiple heat dissipation fins are fixed at equal intervals on the outside of the thin branch pipe.
[0013] The present invention is further configured such that the first transmission assembly includes two intermediate sprockets fixedly connected to the outside of the auger rod located in the middle and side sprockets fixedly connected to the outside of the auger rods located on both sides, and transmission chains are respectively installed on the outside of the two intermediate sprockets and the corresponding side sprockets.
[0014] The present invention is further configured such that the second transmission assembly includes an extension shaft fixedly connected to one end of the auger rod located in the middle near the crushing barrel and an acceleration gearbox fixedly connected to the top of the crushing barrel. A drive sprocket is fixedly connected to the outside of the extension shaft, a driven sprocket is fixedly connected to the input end of the acceleration gearbox, a drive chain is installed on the outside of the driven sprocket and the drive sprocket, and a drive bevel gear meshing with the driven bevel gear is fixedly connected to the output end of the acceleration gearbox.
[0015] The present invention is further configured such that the upper part of the conveying cylinder located in the drying chamber section has evenly distributed air vents.
[0016] This utility model has the following beneficial effects:
[0017] 1. This utility model introduces hot water or steam into the inlet pipe, which then enters multiple thin branch pipes and is discharged from the outlet pipe. When the hot water or steam flows through the thin branch pipes, the heat dissipation fins on the outside of the thin branch pipes can heat the air in the drying chamber, so that the air can reach the temperature required for drying. Then, the exhaust fan is turned on, so that the heated air can quickly come into contact with the corn flour and remove the moisture, thereby drying the corn flour. Finally, it is discharged through the discharge hopper.
[0018] 2. This utility model uses the rotation of the auger rod to drive the extension shaft. The drive sprocket on the extension shaft is connected to the driven sprocket at the input end of the acceleration gearbox via a drive chain. The output end of the acceleration gearbox drives the bevel gear to mesh with the driven bevel gear, thereby driving the crushing shaft to rotate. This causes the crushing blade assembly outside the crushing shaft to crush the corn flour, thus preventing the corn flour from clumping and improving the quality of the corn flour.

Detailed Implementation
[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0031] Example 1
[0032] Please see Figures 1 to 6 This utility model is a drying device for corn flour processing, including a base frame 100; a drying chamber 200 is fixedly provided on the top of the base frame 100, and a heating tube assembly 300 for heating the air inside the drying chamber 200 and a conveying assembly 400 for conveying corn flour are provided at the bottom of the inner cavity of the drying chamber 200; a crushing assembly 500 for breaking up corn flour is provided on one side of the base frame 100.
[0033] The conveying assembly 400 includes three conveying cylinders 401 equidistantly arranged and fixed inside the drying chamber 200. Each of the three conveying cylinders 401 is rotatably connected to an auger rod 402. A first transmission assembly 600 is provided at one end of each of the three conveying cylinders 401 near the input end. A feeding hopper 403 connected to each of the three conveying cylinders 401 is fixed at the input end of each of the three conveying cylinders 401. A discharge hopper 404 connected to each of the three conveying cylinders 401 is fixed at the output end of each of the three conveying cylinders 401. A drive motor 405 is fixed at one end of one of the conveying cylinders 401 near the discharge hopper 404, and the corresponding auger rod 402 is fixed at the output end of the drive motor 405. The rotation of the auger rod 402 can push the corn flour forward, realizing continuous drying operation and improving drying efficiency.
[0034] Specifically, the top and bottom of the drying chamber 200 are respectively provided with an air outlet and an air inlet. The bottom of the drying chamber 200 is fixedly connected to a filter screen 201 covering the bottom of the air inlet. An exhaust fan 202 is installed inside the air outlet. The filter screen 201 can filter impurities in the air, ensuring the cleanliness of the air entering the drying chamber 200 and preventing impurities from contaminating the corn flour. The exhaust fan 202 can accelerate the airflow, allowing the heated air to come into contact with the corn flour more quickly and remove moisture, thereby improving the drying efficiency.
[0035] The heating tube assembly 300 includes an inlet pipe 301 and an outlet pipe 302 fixedly connected to both sides inside the drying chamber 200. Multiple equally spaced fine branch pipes 303 are connected between the inlet pipe 301 and the outlet pipe 302. Hot water or steam flows in the inlet pipe 301, the outlet pipe 302 and the fine branch pipes 303, which can heat the air inside the drying chamber 200 and provide the heat required for drying corn flour.
[0036] The first transmission assembly 600 includes two intermediate sprockets 601 fixedly connected to the outside of the auger rod 402 located in the middle and side sprockets 602 fixedly connected to the outside of the auger rods 402 located on both sides. The two intermediate sprockets 601 are respectively connected to the outside of the corresponding side sprockets 602 with transmission chains 603.
[0037] Furthermore, multiple heat dissipation fins 305 are fixed at equal intervals on the outside of the thin branch pipe 303. The arrangement of heat dissipation fins 305 increases the heat dissipation area of the thin branch pipe 303, allowing heat to be dissipated into the air inside the drying chamber 200 more quickly, improving heating efficiency, and enabling the air to reach the required drying temperature more quickly, thereby shortening the drying time of corn flour and improving the working efficiency of the drying device.
[0038] The feed cylinder 401 is located at the top of the drying chamber 200 and has evenly distributed ventilation holes, which allow the moisture in the corn flour to be discharged.
[0039] The operation process of this embodiment is as follows: When corn flour needs to be dried, corn flour is first poured into the feeding hopper 403, then the drive motor 405 is started, and then the auger rod 402 fixed to the output end of the drive motor 405 starts to rotate. At this time, the two intermediate sprockets 601 outside the middle auger rod 402 rotate accordingly. Since the two intermediate sprockets 601 are respectively connected to the side sprockets 602 outside the auger rods 402 on both sides through the transmission chain 603, the rotation of the intermediate sprockets 601 will drive the side sprockets 602 to rotate through the transmission chain 603, thereby causing the auger rods 402 on both sides to rotate as well, so that the three auger rods 402 can rotate synchronously, and the corn flour can be continuously conveyed in the three conveying cylinders 401.
[0040] During the corn flour conveying process, hot water or steam is introduced into the inlet pipe 301, then into the interior of multiple thin branch pipes 303, and finally discharged from the outlet pipe 302. When the hot water or steam flows through the thin branch pipes 303, the heat dissipation fins 305 on the outside of the thin branch pipes 303 can heat the air in the drying chamber 200 so that the air can reach the temperature required for drying. Then the exhaust fan 202 is activated so that the heated air can quickly come into contact with the corn flour and remove the moisture, thereby drying the corn flour. Finally, it is discharged through the discharge hopper 404.
[0041] Example 2
[0042] Please see Figure 1 , Figure 7 and Figure 8 Based on the first specific embodiment, the crushing assembly 500 includes a crushing barrel 501 fixedly mounted on the base frame 100 near the drive motor 405, and the discharge hopper 404 is connected to the crushing barrel 501. A crushing shaft 502 is rotatably connected inside the crushing barrel 501. Multiple crushing blade sets 503 are fixedly mounted on the outer part of the crushing shaft 502 located in the crushing barrel 501. A driven bevel gear 504 is fixedly mounted on the top of the crushing shaft 502. A second transmission assembly 700 for driving the crushing shaft 502 to rotate is provided on the top of the crushing barrel 501. The crushing assembly 500 can break up and crush the dried corn flour, prevent the corn flour from clumping, and thus improve the quality of the corn flour.
[0043] Specifically, the second transmission assembly 700 includes an extension shaft 701 fixedly connected to one end of the auger rod 402 located in the middle near the crushing barrel 501, and an acceleration gearbox 703 fixedly connected to the top of the crushing barrel 501. A drive sprocket 702 is fixedly connected to the outside of the extension shaft 701. A driven sprocket 704 is fixedly connected to the input end of the acceleration gearbox 703. A drive chain 705 is installed on the outside of the driven sprocket 704 and the drive sprocket 702. A drive bevel gear 706 that meshes with the driven bevel gear 504 is fixedly connected to the output end of the acceleration gearbox 703. The second transmission assembly 700 uses the power of the auger rod 402 to drive the crushing shaft 502 to rotate, eliminating the need for an additional power source and saving energy and cost. The acceleration gearbox 703 can accelerate the power, increasing the rotation speed of the crushing shaft 502, thereby improving crushing efficiency and enabling the corn flour to be broken up and crushed more effectively.
[0044] The operation process of this embodiment is as follows: After the dried corn flour enters the crushing barrel 501, the extension shaft 701 is driven by the rotation of the auger rod 402. The drive sprocket 702 on the extension shaft 701 is connected to the driven sprocket 704 at the input end of the acceleration gearbox 703 through the drive chain 705. The output end of the acceleration gearbox 703 drives the bevel gear 706 to mesh with the driven bevel gear 504, thereby driving the crushing shaft 502 to rotate, so that the crushing blade assembly 503 outside the crushing shaft 502 crushes the corn flour, thereby preventing the corn flour from clumping and improving the quality of the corn flour.
