Description

Technical Field

[0001] This utility model relates to the field of modified starch production technology, specifically to a starch slurry preheating device for modified starch production. Background Technology

[0002] Modified starch is a product obtained by treating natural starch through physical, chemical, or biological methods. Natural starch has limitations such as poor stability and insufficient temperature resistance. Modification treatment can improve its properties, such as enhancing thickening properties, increasing gel strength, and improving water retention.

[0003] In the production process of modified starch, preheating is a crucial step affecting the efficiency of subsequent reactions. However, this stage often faces the dual challenges of sticking to the bottom and excessively high temperatures, which often mutually induce and occur together. When the local temperature of the material rises sharply above the gelatinization critical point, the starch granules will rapidly absorb water, swell, and gelatinize, forming a viscous colloid that adheres to the bottom of the container. This not only causes uneven heat transfer but also exacerbates the accumulation of localized high temperatures. Furthermore, the continuously rising temperature will further promote the gelatinization and adhesion of more starch molecules, creating a vicious cycle. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes a starch slurry preheating device for modified starch production that adopts a uniform heating mode to prevent excessively high bottom temperature and has multi-directional temperature monitoring capabilities.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a starch slurry preheating device for modified starch production, comprising:

[0006] The base has several legs fixedly installed on its bottom surface;

[0007] A preheating tank is fixedly mounted on a base. A heating plate and a heating ring are respectively embedded in the middle and lower part of the side wall. The heating plates are equidistantly distributed around the preheating tank. A discharge pipe is provided at the lower end of the side wall of the preheating tank, and a discharge control valve is provided on the discharge pipe.

[0008] The stirring mechanism includes a support, a stirring shaft, and several stirring blades. The support is detachably mounted on the upper end of the preheating tank. The stirring shaft is rotatably connected to the support and is driven to rotate by a motor fixed on the support. The stirring blades are fixed on the side wall of the stirring shaft and are distributed at equal intervals. Several scrapers are fixedly mounted on the lower end of the stirring shaft and are attached to the bottom surface of the preheating tank.

[0009] The temperature detector is fixed to one side of the stirring shaft via a connecting rod.

[0010] Furthermore, the support legs are located at the four corners of the bottom surface of the base.

[0011] Furthermore, the preheating tank is cylindrical.

[0012] Furthermore, the bracket has U-shaped grooves at both ends that match the upper edge of the preheating tank, and the bracket is fixed to the preheating tank by bolts at both ends.

[0013] Furthermore, the stirring blade is V-shaped.

[0014] Furthermore, a battery is provided on the side wall of the stirring shaft to power the temperature detector.

[0015] Compared with the prior art, the advantages of this utility model are as follows: the device has a heating plate in the middle of the side wall of the preheating tank and a heating ring at the lower end. The heating plates are evenly distributed around the tank body. Combined with the cylindrical tank design, the heat can be transferred to the starch slurry more evenly, reducing local high temperature.

[0016] The temperature detector is fixed to one side of the stirring shaft via a connecting rod. As the stirring shaft rotates, it can detect the temperature of the starch slurry at different locations inside the tank. The battery on the stirring shaft provides power to the detector, ensuring the stability and flexibility of the temperature detection. This allows for timely monitoring of the temperature in different areas of the tank, facilitating timely adjustment of the heating intensity and preventing localized overheating that could lead to starch gelatinization and sticking to the bottom. This also helps improve the preheating effect. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Combined with appendix Figure 3 Appendix Figure 4 A preheating device for starch slurry production of modified starch includes: a base 1, with a plurality of legs 2 fixedly provided on the bottom surface. The legs 2 are located at the four corners of the bottom surface of the base 1, which can make the base more evenly stressed, enhance the stability of the device, and avoid the operation being affected by shaking during the preheating process.

[0024] Combined with appendix Figure 1 Appendix Figure 3 Appendix Figure 4 The preheating tank 3 is fixedly mounted on the base 1. Heating plates 4 and heating rings 5 ​​are embedded in the middle and lower ends of the side wall, respectively. The heating plates 4 are equidistantly distributed around the preheating tank 3. The lower end of the side wall of the preheating tank 3 is provided with a discharge pipe 6, and a discharge control valve 7 is provided on the discharge pipe 6. The preheating tank 3 is cylindrical, which facilitates the uniform stirring of starch slurry by the stirring mechanism, reduces dead corners in the stirring, and also facilitates uniform heat transfer of the heating components.

[0025] Combined with appendix Figure 1 Appendix Figure 4 The stirring mechanism includes a support 8, a stirring shaft 9 and several stirring blades 10. The support 8 is detachably mounted on the upper end of the preheating tank 3. Both ends of the support 8 are provided with U-shaped buckles that match the upper edge of the preheating tank 3. Both ends of the support 8 are connected and fixed to the preheating tank 3 by bolts 15. The installation and disassembly are convenient, and the stirring mechanism is easy to maintain or replace.

[0026] Combined with appendix Figure 1 Appendix Figure 2 The stirring shaft 9 is rotatably connected to the support 8 and is driven to rotate by the motor 11 fixed on the support 8. The stirring blades 10 are fixed on the side wall of the stirring shaft 9 and are distributed at equal intervals. Several scrapers 12 are fixedly provided at the lower end of the stirring shaft 9. The scrapers 12 are set in contact with the bottom surface of the preheating tank 3. The stirring blades 10 are V-shaped plates, which can enhance the stirring effect on the starch slurry, improve the stirring efficiency, and make the starch slurry heat more evenly.

[0027] Combined with appendix Figure 1 Appendix Figure 2 The temperature detector 13 is fixed to one side of the stirring shaft 9 via a connecting rod 14. A battery 16 is provided on the side wall of the stirring shaft 9 to power the temperature detector 13. No additional wiring is required, ensuring the independence and stability of temperature detection, and it can adapt to the rotation of the stirring shaft 9, making it more flexible to use.

[0028] The specific implementation of this utility model is as follows: Starch slurry is injected into the preheating tank 3. The bracket 8 is fixed to the upper end of the preheating tank 3 via U-shaped grooves at both ends and secured with bolts 15. The device is connected to an external power source, and the motor 11 is started to drive the stirring shaft 9 to rotate. The stirring blades 10 rotate with the shaft to stir the starch slurry. The V-shaped stirring blades 10 enhance the stirring effect, and the scraper 12 rotates against the bottom surface of the tank to prevent starch slurry from depositing and sticking to the bottom.

[0029] During heating, the heating plate 4 on the side wall and the heating ring 5 at the bottom work simultaneously, and heat is evenly transferred through the cylindrical tank wall. Stirring further ensures more even heating of the starch slurry. The temperature detector 13 rotates with the stirring shaft 9, monitoring the temperature at different locations in real time. The battery 16 provides power to ensure stable operation. When the temperature reaches the preset value, the heating components are turned off, the discharge control valve 7 is opened, and the starch slurry is discharged through the discharge pipe 6. Throughout the process, uniform heating and stirring, combined with real-time temperature monitoring, effectively prevent sticking to the bottom and localized overheating.
