Description

Technical Field

[0001] This utility model relates to the technical field of modified starch production equipment, specifically an environmentally friendly ultrasonic-enhanced reaction device for modified starch. Background Technology

[0002] To improve starch properties and expand its applications, starch is treated using physical, chemical, or enzymatic methods. This introduces new functional groups into the starch molecules or alters the size of the starch molecules and the properties of the starch granules, thereby changing the natural characteristics of starch (such as gelatinization temperature, thermal viscosity and its stability, freeze-thaw stability, gelling power, film-forming properties, and transparency) to better suit the requirements of specific applications. Starch that has undergone secondary processing and had its properties altered is collectively called modified starch.

[0003] In the industrial production of modified starch, the reaction device, as the core processing equipment, plays a decisive role in product quality and production efficiency. Currently, most mainstream modified starch reaction devices employ mechanical stirring as the primary reaction-promoting method. However, this single power input method has significant limitations: the flow field distribution generated by traditional stirring blades is uneven, making it difficult to achieve thorough mixing of the reaction system, resulting in significant differences in local reaction rates. Therefore, this application proposes an environmentally friendly ultrasonic-enhanced reaction device for modified starch. Utility Model Content

[0021] 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.

[0022] Please see Figures 1 to 5 This utility model provides a technical solution: an environmentally friendly ultrasonic enhanced reaction device for modified starch, including a reaction tank 1, an inner shell 2 fixedly installed on the top of the inner wall of the reaction tank 1, and multiple feed pipes 4 inserted into the top of the reaction tank 1. A stirring motor 5 is also installed on the top of the reaction tank 1, and a rotating rod 6 is fixedly installed at the bottom of the stirring motor 5. The bottom end of the rotating rod 6 passes through the top of the reaction tank 1 and extends into the inner cavity of the inner shell 2. The rotating rod 6 is movably connected to the top of the reaction tank 1, and multiple stirring blades 7 are fixedly installed on the outer wall of the rotating rod 6. A discharge pipe 8 is inserted into the bottom of the inner shell 2, and a sealing component is provided at the bottom of the discharge pipe 8. A positioning ring 10 is fixedly installed on the outer wall of the discharge pipe 8, and multiple sets of ultrasonic transmitters 11 are installed on the top of the positioning ring 10. The multiple sets of ultrasonic transmitters 11 are evenly distributed on the outer side of the inner shell 2.

[0023] In this embodiment, during use, the raw materials are first injected into the inner shell 2 through multiple feed pipes 4, and the stirring motor 5 is driven, so that the stirring motor 5 drives the rotating rod 6 to rotate, and the rotating rod 6 drives multiple stirring blades 7 to rotate synchronously. The stirring blades 7 stir inside the inner shell 2 to promote the reaction of modified starch. In addition, the multiple stirring blades 7 can also scrape the inner wall of the inner shell 2 to clean the inner wall of the inner shell 2. Subsequently, multiple ultrasonic transmitters 11 can be used to generate ultrasonic waves synchronously. The ultrasonic waves are used in conjunction with multiple sets of stirring blades 7 to achieve rapid reaction of modified starch inside the inner shell 2, thereby enhancing the reaction. After the reaction is completed, the sealing component is opened, so that the modified starch that has completed the reaction is discharged through the feed pipe 8.

[0024] As an optional implementation, the sealing assembly includes a ramp 17, which is fixedly installed in the inner cavity of the feed tube 8. The outer wall of the ramp 17 is arc-shaped, and the bottom of the ramp 17 extends to the bottom of the feed tube 8. A groove 18 is provided at the bottom of the ramp 17. A movable block 19 is provided in the inner cavity of the groove 18. A sealing plate 20 is fixedly installed on the outer wall of the movable block 19. The top of the sealing plate 20 fits against the bottom of the feed tube 8. A round shaft 21 is fixedly installed through the movable block 19. Both ends of the round shaft 21 pass through the inner wall of the groove 18 and are rotatably connected to the inner wall of the groove 18. A servo motor 16 is fixedly installed at one end of the round shaft 21.

[0025] In this embodiment, during use, the servo motor 16 is first driven, causing the servo motor 16 to drive the circular shaft 21 to rotate. The circular shaft 21 drives the movable block 19 to rotate, and the movable block 19 drives the sealing plate 20 to rotate, causing the sealing plate 20 to gradually move away from the feeding pipe 8. At this time, the bottom of the feeding pipe 8 is semi-open, and the modified starch inside is directly discharged. After all the modified starch is discharged, the servo motor 16 is driven to rotate in the opposite direction to reset the sealing plate 20 and reattach it to the top of the feeding pipe 8 to seal the bottom of the feeding pipe 8.

[0026] As an optional implementation, a base 15 is fixedly installed on the outer wall of the servo motor 16, and the base 15 is fixedly connected to the outer wall of the feed tube 8.

[0027] In this embodiment, during use, the base 15 is used to fix the servo motor 16 to the outer wall of the feeding tube 8, thereby improving the stability of the servo motor 16 during subsequent operation.

[0028] As an optional implementation, a fixing bracket 14 is fixedly installed on the outer wall of the base 15, and the fixing bracket 14 is sleeved and fixedly installed on the outer wall of the feed pipe 8.

[0029] In this embodiment, during use, the fixing bracket 14 is used to fix the base 15 to the outer wall of the feeding tube 8, further ensuring the stable performance of the servo motor 16 during subsequent operation.

[0030] As an optional implementation, the inner wall of the inner shell 2 is provided with an internal thread 3, and the outer wall of the feed tube 8 is provided with an external thread 9, with the top of the feed tube 8 threadedly connected to the inner cavity of the inner shell 2.

[0031] In this embodiment, during use, the internal thread 3 and the external thread 9 are used to install the feed tube 8 and the inner shell 2 by means of threaded connection. The whole device can be disassembled into two parts for easy transportation of the device, and the installation is convenient after transportation.

[0032] As an optional implementation, an outer fixing ring 12 is sleeved and fixedly installed on the outer wall of the feed pipe 8, and multiple support frames 13 are sleeved and fixedly installed on the outer wall of the outer fixing ring 12.

[0033] In this embodiment, during use, the cooperation of multiple support frames 13 is used to support the overall device, making the overall device more stable during operation.

[0034] As an optional implementation, the outer diameter of the sealing plate 20 is set to be larger than the inner diameter of the feed pipe 8.

[0035] In this embodiment, during use, this setting enables the sealing plate 20 to achieve a more complete sealing effect on the feed pipe 8, effectively preventing leakage.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
