Description

Technical Field

[0001] This utility model relates to the field of starch drying technology, specifically a starch drying device. Background Technology

[0002] Starch is a high-molecular-weight carbohydrate composed of glucose molecules. It belongs to the category of polysaccharides. The processing technology of starch includes cleaning, soaking, crushing, sieving, sedimentation, drying and grinding. Starch is widely used, especially in cooking, where it is often used as a thickener to help make the ingredients smooth and to thicken the sauce.

[0003] A starch drying device disclosed in Chinese Patent Publication No. CN220270012U includes a connecting body. A support base is bolted to the bottom of the connecting body. A heating box is fixedly connected to the bottom of the connecting body. A connector is installed on the right side of the heating box at the bottom of the connecting body. A louvered plate is fixedly connected inside the connecting body. An auxiliary frame is installed at the top of the louvered plate inside the connecting body. A placement mesh plate is fixedly connected inside the auxiliary frame. In use, this starch drying device, through the cooperation of the auxiliary frame, placement mesh plate, connecting vertical plate, connecting horizontal plate, and ribbon, effectively repels flies and mosquitoes from above the starch to be dried inside the placement mesh plate, ensuring the quality of the dried starch and thus improving the stability of the starch drying device.

[0004] In the process of realizing this application, the inventors discovered that the technology has at least the following problems: Although the above technical solution can drive away flies and mosquitoes when drying starch and ensure the quality of the dried starch, the starch piles up together during the drying process, so the starch in the middle cannot be completely dried, which will affect the drying quality of the starch. Therefore, further improvements can be made. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides the following technical solution: a starch drying device, comprising a frame, a drying frame installed in the middle of the frame, drying pipes installed inside the frame and on both the upper and lower sides of the drying frame, a hot air blower fixedly installed on the base of the frame, an exhaust pipe connected to the exhaust port of the hot air blower, the exhaust pipe having two ends, which are respectively connected to the upper and lower drying pipes, a gear reduction motor fixedly installed at the top center of the frame, a starch stirring assembly installed inside the drying frame, and the gear reduction motor driving the starch stirring assembly.

[0006] As an optimization, the drying pipe includes several annular pipes installed inside the frame, and the branch end of the exhaust pipe is connected to the outermost annular pipe. A connecting pipe connects any two adjacent annular pipes. A nozzle is provided on the side of the annular pipe opposite to the drying frame. Hot air is discharged along the exhaust pipe by a hot air generator and then slowly discharged from the nozzle along the annular pipe, thereby drying the corn starch in the middle drying frame.

[0007] As an optimization, the inner diameter of each of the annular tubes is different, and they are arranged in a way that diffuses outward from the center.

[0008] As an optimization, the starch stirring assembly includes a rotating shaft fixedly mounted at the bottom of the output shaft of a gear reducer motor via a coupling. A rotating seat is fixedly mounted at the bottom of the rotating shaft. Three stirring rods are rotatably connected to the outer side of the rotating seat. Spiral blades are fixedly mounted on the outer side of the stirring rods. By starting the gear reducer motor, the rotating shaft will rotate, which in turn will cause the spiral blades to rotate inside the drying frame, thereby stirring the corn starch inside the drying frame.

[0009] As an optimization, a roller is fixedly installed at the end of the stirring rod. The roller rolls against the bottom wall of the drying frame. When the stirring rod rotates around the axis, it will drive the roller to roll along the bottom wall of the drying frame, which in turn will drive the stirring rod to rotate.

[0010] As an optimization, a ball bearing is embedded in the center of the roller, and an annular groove is formed on the inner wall of the drying frame corresponding to the ball bearing. The ball bearing is rotatably connected in the annular groove, and the ball bearing rolls along the annular groove to play a limiting and guiding role.

[0011] As an optimization, a scraper is rotatably connected to the outer side of the stirring rod near the roller, and the scraper slides against the bottom wall of the drying frame. The scraper has a protruding bump in the middle, and the bump is slidably connected in the ring groove. The rotation of the stirring rod will drive the scraper to rotate synchronously along the inner wall of the drying frame, thereby cleaning the starch in front of the roller's rolling path.

[0012] The beneficial effects of this utility model are: 1. This starch drying device uses nozzles to blow hot air from the annular pipe to the upper and lower sides of the drying frame, thus drying the corn starch from both sides. The gear reduction motor drives the starch tumbling component to rotate, which causes the stirring rod to drive the spiral blade to rotate inside the drying frame. The rolling of the rollers causes the spiral blade to rotate on its own axis while revolving around the central axis, thus stirring and exposing the corn starch in the middle, thereby improving the drying quality.

[0013] 2. When the stirring rod rotates, it drives the scraper to rotate synchronously along the inner wall of the drying frame. This scrapes away and cleans the starch in front of the rolling path of the roller, preventing the accumulated corn starch from affecting the rolling of the roller. At the same time, the protrusion rotates along the inner wall of the ring track groove, thus cleaning the corn starch embedded in the ring track groove and preventing it from affecting the rolling of the ball in the ring track groove.

[0016] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] Please see Figure 1A starch drying device includes a frame 1, a drying frame 2 installed in the middle of the frame 1, drying pipes 3 installed inside the frame 1 and on the upper and lower sides of the drying frame 2, a hot air blower 4 fixedly installed on the base of the frame 1, an exhaust pipe 5 connected to the exhaust port of the hot air blower 4, the exhaust pipe 5 having two branches at the end, and the two branches respectively connected to the upper and lower drying pipes 3, a gear reduction motor 6 fixedly installed at the top center of the frame 1, a starch stirring assembly 7 installed inside the drying frame 2, and the gear reduction motor 6 driving the starch stirring assembly 7.

[0019] Please see Figure 2 The drying pipe 3 includes several annular pipes 8 installed inside the frame 1. Each annular pipe 8 has a different inner diameter and is arranged in a way that spreads outward from the center. The branch end of the exhaust pipe 5 is connected to the outermost annular pipe 8. A connecting pipe 9 connects any two adjacent annular pipes 8. A nozzle 10 is provided on one side of the annular pipe 8 opposite to the drying frame 2. Hot air is slowly discharged along the exhaust pipe 5 by the hot air blower 4 and then discharged from the nozzle 10 along the annular pipe 8. This allows the corn starch in the middle drying frame 2 to be dried. The drying is carried out simultaneously from the top and bottom sides, thereby improving the drying efficiency. Please see Figure 3-4 The starch stirring assembly 7 includes a rotating shaft 11 fixedly mounted at the bottom of the output shaft of the gear reducer motor 6 via a coupling. A rotating seat 12 is fixedly mounted at the bottom of the rotating shaft 11. Three stirring rods 13 are rotatably connected to the outer side of the rotating seat 12. Spiral blades 14 are fixedly mounted on the outer side of the stirring rods 13. When the gear reducer motor 6 is started, the rotating shaft 11 will rotate, which will in turn drive the spiral blades 14 to rotate inside the drying frame 2. This will stir the corn starch inside the drying frame 2, preventing the corn starch in the middle from not being dried and improving the drying effect. Also, because the gear reducer motor 6 rotates at a relatively slow speed, the starch will not be scattered in all directions. Please see Figure 3-4 A roller 15 is fixedly installed at the end of the stirring rod 13. The roller 15 rolls against the bottom wall of the drying frame 2. When the stirring rod 13 rotates around the rotating shaft 11, it will drive the roller 15 to roll along the bottom wall of the drying frame 2, which will in turn drive the stirring rod 13 to rotate. This will enable the spiral blade 14 to rotate and further stir the corn starch, making the corn starch more evenly dried. Please see Figure 3-4 The center of the roller 15 is embedded with a ball 16, and the inner wall of the drying frame 2 is provided with a ring groove 17 corresponding to the ball 16. The ball 16 is rolled in the ring groove 17. The ball 16 rolls along the ring groove 17, which plays a role in limiting and guiding, and improving rotational stability. Please see Figure 3-4A scraper 18 is rotatably connected to the outer side of the stirring rod 13 near the roller 15, and the scraper 18 slides against the bottom wall of the drying frame 2. The scraper 18 has a protruding protrusion 19 in the middle, and the protrusion 19 is slidably connected in the annular groove 17. The rotation of the stirring rod 13 will drive the scraper 18 to rotate synchronously along the inner wall of the drying frame 2, thereby cleaning the starch in front of the rolling path of the roller 15 and preventing the accumulated corn starch from affecting the rolling of the roller 15. At the same time, the rotation of the protrusion 19 along the inner wall of the annular groove 17 will clean the corn starch embedded in the annular groove 17 and prevent it from affecting the rolling of the ball 16 in the annular groove 17.

[0020] When in use, first start the hot air blower 4, which will discharge hot air into the annular pipe 8 along the exhaust pipe 5, and then through the nozzle 10, the hot air will slowly blow onto the upper and lower surfaces of the drying frame 2, so that the corn starch can be dried from both sides at the same time without blowing the starch up. At the same time, by starting the gear reduction motor 6 to drive the starch stirring component 7 to rotate, the stirring rod 13 will drive the spiral blade 14 to rotate inside the drying frame 2, so the roller 15 will roll along the bottom wall of the drying frame 2, and the spiral blade 14 will rotate on its own axis while revolving around the inner wall of the drying frame 2, thus evenly stirring the corn starch, so that the corn starch in the middle is stirred out, further improving the drying quality.

[0021] In summary, this starch drying device uses nozzle 10 to blow hot air from the annular pipe 8 to the upper and lower sides of the drying frame 2, thereby drying the corn starch from both sides. The gear reduction motor 6 drives the starch stirring component 7 to rotate, which causes the stirring rod 13 to drive the spiral blade 14 to rotate inside the drying frame 2. The roller 15 rolls, causing the spiral blade 14 to rotate on its own axis while revolving around the central axis, thus stirring and exposing the corn starch in the middle, thereby improving the drying quality. When the stirring rod 13 rotates, it drives the scraper 18 to rotate synchronously along the inner wall of the drying frame 2, thus scraping away the starch in front of the rolling path of the roller 15 for cleaning, preventing the accumulated corn starch from affecting the rolling of the roller 15. At the same time, the protrusion 19 rotates along the inner wall of the ring groove 17, thus cleaning the corn starch embedded in the ring groove 17, thereby preventing it from affecting the rolling of the ball 16 in the ring groove 17.
