Description

Technical Field

[0001] This utility model belongs to the technical field of drying equipment, specifically referring to a drying device for processing modified starch. Background Technology

[0002] Modified starch undergoes various treatments to alter its original physical or chemical properties to varying degrees. Based on the inherent properties of natural starch, physical, chemical, or enzymatic treatments are used to improve starch performance and expand its applications. These treatments introduce new functional groups into starch molecules or change the size of starch molecules and the properties of starch granules, thereby altering the natural characteristics of starch.

[0003] In existing technologies, drying devices for modified starch processing typically employ a single-stage drying process, resulting in poor heating uniformity. The mixing chamber often relies on a single stirring or airflow drive, leading to uneven distribution of the heating medium. Materials tend to accumulate on the walls or stagnate in certain areas, and there are differences in heating time, which can easily cause uneven drying problems.

[0004] Furthermore, the moisture removal efficiency is low, and the starch quality is easily degraded. In order to remove bound water, single-stage drying requires increasing the chamber temperature. Under high temperature conditions, the starch molecular chains are easily broken, the viscosity decreases, and full contact with air intensifies oxidation, causing the color to turn yellow. Utility Model Content

[0008] The multi-stage drying unit includes two sets of partition plates that penetrate the cylindrical horizontal shell. The partition plates are provided with guide ports located inside the cylindrical horizontal shell. The two sets of partition plates divide the cylindrical horizontal shell into a pre-drying chamber, a deep drying chamber, and a uniform drying chamber arranged sequentially along the material conveying direction.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0026] Example 1:

[0027] like Figure 1 , 2 As shown in Figure 3, the present invention proposes a drying device for modified starch processing, comprising a cylindrical horizontal shell 1, with a feeding machine shell 11 sleeved at one end of the cylindrical horizontal shell 1, a feeding hopper 12 connected to the cylindrical horizontal shell 1 on the feeding machine shell 11, and a discharging machine shell 13 sleeved at the other end of the cylindrical horizontal shell 1, with a discharging port 14 connected to the cylindrical horizontal shell 1 at the lower part of the discharging machine shell 13. The device also includes a multi-stage drying unit; the multi-stage drying unit includes... Two sets of partition plates 2 are installed through the cylindrical horizontal shell 1. The partition plates 2 are provided with guide ports 21 located inside the cylindrical horizontal shell 1. The two sets of partition plates 2 divide the cylindrical horizontal shell 1 into a pre-drying chamber 22, a deep drying chamber 23 and a uniform drying chamber 24 arranged sequentially along the material conveying direction. A motor 3 is installed through one side of the cylindrical horizontal shell 1. A rotating rod 31 is fixed to the output shaft of the motor 3, which is installed through the two sets of partition plates 2. The rotating rod 31 is provided with multiple sets of spiral blades 32.

[0028] In use, raw materials are added into the cylindrical horizontal shell 1 through the feed hopper 12. The motor 3 drives the rotating rod 31 to rotate, and the spiral blades 32 push the material through the pre-drying chamber 22, the deep drying chamber 23 and the uniform drying chamber 24 for multi-stage processing. Finally, the material is discharged from the discharge port 14. The partition plate 2 separates the space, and the guide port 21 guides the material to pass through, avoiding material blockage.

[0029] Multiple sets of air inlet nozzles 4 are connected to the side wall of the pre-drying chamber 22. An air inlet housing 41 is connected to the air inlet nozzle 4, and a hot air connecting valve 42 is connected to the air inlet housing 41. An air outlet 5 is opened at the upper part of the pre-drying chamber 22, and a filter screen 51 is provided inside the air outlet 5.

[0030] First, the material undergoes rapid surface dehydration in the pre-drying chamber 22. The hot air connecting valve 42 is connected to an external hot air source. After the hot air enters the air inlet casing 41, it is sprayed out from multiple sets of air inlet nozzles 4. The hot air is in a 30° downward tangential direction, which forms a forward assist with the material's falling trajectory, prolonging the contact time between the hot air and the material, ensuring that the surface free water is fully evaporated, and the moisture is discharged from the air outlet 5. The filter screen 51 plays a role in blocking the material.

[0031] like Figure 1 As shown, a heating jacket 6 is fitted onto the outer wall of the deep dry chamber 23. The heating jacket 6 has a cavity inside. A water injection pipe 61 is connected to one side of the heating jacket 6, and a water outlet pipe 62 is connected to the other side of the heating jacket 6. A circulating water tank 7 connected to the water outlet pipe 62 is provided below the heating jacket 6. A pump 71 is connected to the circulating water tank 7. The water outlet of the pump 71 is connected to the water injection pipe 61. Electric heating modules 72 are provided on both sides of the circulating water tank 7.

[0032] After the material enters the deep drying chamber 23, during use, the water in the circulating water tank 7 is heated by the electric heating module 72. When the pump 71 is working, hot water is drawn out and sent into the heating jacket 6 through the water injection pipe 61 to heat the deep drying chamber 23, thereby achieving deep heating and drying of the material. The deep drying chamber 23 is also equipped with an air outlet 5 for dehumidification. The water outlet pipe 62 sends the hot water into the circulating water tank 7 to complete the circulation.

[0033] Example 2:

[0034] like Figure 3 , 4As shown, the deep dry chamber 23 is provided with multiple sets of straight plate-shaped stirring blades 8 evenly distributed on the rotating rod 31. The ends of the straight plate-shaped stirring blades 8 are folded. When the straight plate-shaped stirring blades 8 rotate, the end that first contacts the material folds upward at a 15° angle. When turning the material, it can better catch the material and throw it upward. It is more uniform than pure straight plate turning and does not increase wind resistance. It plays a stirring role and improves the uniformity of material heating.

[0035] The pitch of the spiral blades 32 located in the equal drying chamber 24 is smaller than that of the spiral blades 32 located in the pre-drying chamber 22 and the deep drying chamber 23. The reduced pitch of the spiral blades 32 in this section results in a slower material conveying speed and a longer material residence time. After the material enters the equal drying chamber 24, it plays a role in balancing the uniform distribution of moisture.

[0036] The above is the entire operating procedure of a drying device for processing modified starch.

[0037] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.

[0038] Unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. 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 between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
