Description

Technical Field

[0001] This utility model relates to the field of sweet potato starch processing technology, and in particular to an ultrasonic-assisted antioxidant treatment device for sweet potato starch processing. Background Technology

[0002] Sweet potatoes are a widely cultivated crop, rich in starch, and sweet potato starch has a wide range of applications in the food, chemical, and other fields. With the increasing market demand for sweet potato starch and the ever-improving requirements for starch quality, traditional sweet potato starch processing technology faces many challenges and needs continuous improvement and innovation to enhance starch quality and production efficiency. During sweet potato starch processing, starch is easily affected by oxidation, leading to a decline in its quality.

[0003] Typical sweet potato starch processing equipment using ultrasonic-assisted antioxidant treatment consists of an ultrasonic device, a starch reaction device, and a control device. The ultrasonic device generates a cavitation effect through high-frequency vibration, creating instantaneous high-pressure and low-pressure cycles in the liquid, which causes changes in the starch molecule structure and activates antioxidant components. The starch reaction device provides a mixing and reaction space for the materials, and the stirring system ensures that the sweet potato starch and antioxidants come into uniform contact. The control device adds antioxidants and sweet potato starch through a conveying device, ensuring the efficiency of antioxidant treatment and the stability of starch quality.

[0004] In the aforementioned technologies, the ultrasonic energy distribution within the mixing tank of some devices is not uniform enough, resulting in an inability to perform efficient and uniform ultrasonic-assisted antioxidant treatment on sweet potato starch. This makes it difficult for starch granules to fully absorb antioxidants, affecting the antioxidant performance of the final product. Furthermore, the mixing structure fails to achieve a good synergistic effect with ultrasonic treatment, leading to insufficient mixing of materials within the mixing tank. This inconsistency causes starch granules to accumulate and adhere within the tank. Such accumulation and adhesion not only affect the uniformity of material mixing but also cause excessive or insufficient ultrasonic energy concentration in localized areas, further reducing the effectiveness of ultrasonic-assisted antioxidant treatment. It also increases the difficulty of equipment cleaning and maintenance, impacting production efficiency and product quality stability. Therefore, an ultrasonic-assisted antioxidant treatment device for sweet potato starch processing is proposed to address these issues. Utility Model Content

Positioning block 44 limits and supports the conveying pipe 51. A connecting bolt 45 is fixedly connected to the other side of the top of the bottom arc plate 42. The connecting bolt 45 cooperates with the control button 47 on the top arc plate 46 to realize the connection and fixation of the bottom arc plate 42 and the top arc plate 46. The control button 47 is threadedly connected to the outer inner side of the top arc plate 46. By rotating the control button 47, the anti-arc plate 48 is moved to realize the adjustment of the clamping force on the conveying pipe 51. The other end of the control button 47 is rotatably connected to the anti-arc plate 48. Driven by the control button 47, the anti-arc plate 48 contacts the top of the conveying pipe 51 and applies pressure to the conveying pipe 51. The outer support of the anti-arc plate 48 is on the bottom inner side of the top arc plate 46.

[0037] Reference Figure 2 and Figure 4 The conveying mechanism 5 includes a conveying pipe 51, which serves as a material conveying channel for conveying materials such as sweet potato starch.

[0038] Working principle: After the control motor 32 starts, the transmission rod 33 at its output end begins to rotate, driving the ultrasonic device 34 fixedly connected to it to operate. The ultrasonic device 34 generates ultrasonic waves to process the sweet potato starch in the mixing tank 31. At the same time, the stirring blade 35 outside the ultrasonic device 34 rotates with the ultrasonic device 34 to stir the material. The scraper 36 at the bottom of the ultrasonic device 34 scrapes the bottom of the mixing tank 31 during the stirring process. When it is necessary to discharge the material, the collection port 371 at the bottom of the mixing tank 31 collects the material and discharges it through the discharge pipe 372. In addition, the push motor 382 outside the support frame 1 drives the support arc plate 383. With the cooperation of the extension plate 381, the support arc plate 383 supports or releases the mixing tank 31.

[0039] The support plate 41 is fixed to the top of the support frame 1. The bottom arc plate 42 at the top of the support plate 41 is connected to the top arc plate 46 through the rotating shaft 43. The top arc plate 46 can rotate around the rotating shaft 43. The limiting block 44 at the top of the bottom arc plate 42 supports the conveying pipe 51. The connecting bolt 45 cooperates with the control button 47 on the top arc plate 46. When the control button 47 rotates, it drives the anti-arc plate 48 to move, thereby fixing the conveying pipe 51. The dividing ring 52 inside the conveying pipe 51 divides it into two areas. The rotating motors 54 on both sides drive the rotating conveyor 55 to rotate inside the conveying pipe 51. The placement cone 53 serves as the material inlet. The material enters the conveying pipe 51 through the placement cone 53 and moves under the push of the rotating conveyor 55.
