Description

Technical Field

[0001] This utility model relates to the field of starch production, specifically an ultrasonic amylose extraction device. Background Technology

[0002] Extraction of starch from plants is an indispensable technique in traditional cooking and modern industry. The traditional manual extraction of starch from plants has a long history. However, the extraction rate of starch from plants varies. The starch contained in plants is a non-water-soluble and finely distributed substance. Starch itself does not have fluidity, so the extraction process is very difficult and complex.

[0003] Ultrasonic extraction of starch requires the raw materials containing starch to be chopped or crushed and added to a solvent beforehand. Ultrasonic waves are then emitted into the container through an ultrasonic generator probe. The cavitation effect and mechanical action of the ultrasound effectively break down the cell walls of the materials, allowing intracellular substances to separate and dissolve into the solvent. Simultaneously, it accelerates molecular motion, enabling rapid contact with the solvent and thus improving extraction efficiency. Current ultrasonic extraction equipment is often used in conjunction with a stirring device, which can significantly improve extraction efficiency and effect. However, the existing ultrasonic and stirring mechanisms are independent, resulting in limited synergistic effects and significantly increasing the space occupied by the equipment. Therefore, it is necessary to develop an ultrasonic amylose extraction device to address the shortcomings of existing technologies. Utility Model Content

Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0023] Example 1

[0024] like Figures 1 to 4 As shown, an ultrasonic amylose extraction device includes an extraction cylinder 1, an agitation component 2 is provided inside the extraction cylinder 1, the upper end of the agitation component 2 extends to the top of the extraction cylinder 1 and is connected to a transmission mechanism 3, a feeding hopper 4 is connected to the top of the extraction cylinder 1, the bottom of the agitation component 2 is connected to the bottom of the inner cavity of the extraction cylinder 1, and a drive mechanism and an ultrasonic power supply are also provided at the top of the extraction cylinder 1.

[0025] The stirring component 2 includes a transmission rod 21 that passes through the inside of the extraction cylinder 1. A plurality of uniformly distributed ultrasonic transducers 22 are fixedly connected to the outer surface of the transmission rod 21. Each ultrasonic transducer 22 is connected to an ultrasonic power box via a wire passing through the inside of the transmission rod 21. The end of the ultrasonic transducer 22 away from the transmission rod 21 is connected to a flow guiding component 23. The end of the flow guiding component 23 away from the transmission rod 21 and the ultrasonic transducer 22 is close to the inner wall of the extraction cylinder 1. With the cooperation of the power box, the ultrasonic transducers 22 can output ultrasonic vibrations with the cooperation of the flow guiding component 23. Under the full stirring of the mixture in the extraction cylinder 1 by the flow guiding component 23, the running efficiency of cells in the mixture is increased, which can significantly improve the efficiency of ultrasonic cavitation effect on cells, thereby effectively improving the efficiency of extracting intracellular substances.

[0026] like Figure 1 As shown, the drive mechanism is fixedly installed on the top of the extraction cylinder 1 by a bracket. The drive mechanism adopts a forward and reverse motor. The output end of the forward and reverse motor is connected to the drive gear, which is connected to the transmission mechanism 3. Under the action of the forward and reverse motor, the stirring action can be increased, avoiding the situation where the fixed stirring effect is not obvious, thereby helping to improve the stirring and mixing effect.

[0027] like Figure 1 and Figure 2 As shown, one end of the wire passing through the transmission rod 21 is fixedly connected to the ultrasonic transducer 22, and the other end is connected to the ultrasonic power box through a contact ring. Due to the setting of the contact ring, it can be ensured that the ultrasonic transducer 22 can be connected to the power box through the wire, and the situation of the wire getting tangled and knotted due to the ultrasonic transducer 22 rotating with the transmission rod 21 can be avoided.

[0028] like Figure 2 and Figure 3 As shown, the flow guiding component 23 includes a connecting sleeve 231 disposed at one end of the ultrasonic transducer 22. The top of the connecting sleeve 231 is integrally formed with a flow guiding stirring plate 232. The outer surfaces of both the connecting sleeve 231 and the flow guiding stirring plate 232 are smooth, and the connection between the two is smooth. Due to the setting of the flow guiding stirring plate 232, the stirring area of ​​the flow guiding component 23 is increased under the cooperation of the connecting sleeve 231 and the connecting rod 233, thereby improving the stirring effect.

[0029] like Figure 3 and Figure 4 As shown, a connecting rod 233 is inserted inside the connecting sleeve 231. One end of the connecting rod 233 near the transmission rod 21 extends to the outside of the connecting sleeve 231 and is fixedly connected to the end of the ultrasonic transducer 22.

[0030] like Figure 3 and Figure 4As shown, the inner diameter of the connecting sleeve 231 is larger than the outer diameter of the connecting rod 233. A shaft sealing ring 236 is connected to both ends of the connecting sleeve 231 and the connecting rod 233. The connecting sleeve 231 and the connecting rod 233 are independent of the interior of the extraction cylinder 1 through the shaft sealing ring 236. Due to the setting of the shaft sealing ring 236, the connecting sleeve 231 and the guide stirring plate 232 can follow the movement of the connecting rod 233 with the cooperation of the positioning bearing 234, and the stability of their synchronous movement can be improved.

[0031] like Figure 4 As shown, two positioning bearings 234, located between two shaft sealing rings 236, are rotatably connected between the connecting sleeve 231 and the connecting rod 233. Two connecting positioning springs 235, located between the two positioning bearings 234, are also provided between the connecting sleeve 231 and the connecting rod 233. One end of each connecting positioning spring 235 is connected to the inner wall of the connecting sleeve 231, and the other end is connected to the outer surface of the connecting rod 233. Under the constraint of the connecting positioning springs 235, the guide stirring blade 232 rotates with the connecting sleeve 231 and is always positioned above the connecting sleeve 231. Due to the connection positioning springs... The setting of 235 ensures that the guide stirring plate 232 is always vertically positioned at the top of the connecting sleeve 231 under the action of its elastic restoring force. As it rotates around the transmission rod 21 along with the connecting sleeve 231 and the connecting rod 233, the guide stirring plate 232 is tilted due to the obstruction of the mixture in the extraction cylinder 1. Moreover, the guide stirring plate 232 can be tilted regardless of whether the drive mechanism rotates forward or backward. More importantly, under the tilting motion of the guide stirring plate 232, an upward oblique thrust can be applied to the contacted mixture, thereby achieving both lateral stirring and longitudinal tumbling, thus effectively improving the stirring effect.

[0032] Example 2

[0033] Assemble the equipment as shown in the figure. Add the mixture into the extraction cylinder 1 through the feeding hopper 4. Turn on the power to make the drive mechanism and ultrasonic box run.

[0034] With the help of the ultrasonic box, the ultrasonic transducer 22 is guided to run and emit ultrasonic waves, so that the ultrasonic waves form a cavitation effect in the extraction tube 1, which acts on the cell wall of the mixture and causes the substances inside to be separated quickly.

[0035] Under the action of the drive mechanism, the transmission mechanism 3 drives the transmission rod 21 to rotate forward and backward, and then drives the connecting rod 233 to rotate forward and backward along the inside of the extraction cylinder 1 through the ultrasonic transducer 22. Since the movement of the connecting rod 233 can drive the connecting sleeve 231 and the guide stirring plate 232 to rotate around the transmission rod 21 with the cooperation of the positioning bearing 234, the shaft sealing ring 236 and the connecting positioning spring 235, when the connecting sleeve 231 and the guide stirring plate 232 rotate, under the resistance of the mixture in the extraction cylinder 1 and the elastic restoring force of the positioning bearing 234, the guide stirring plate 232 is tilted and rotates around the transmission rod 21. Then, when the mixture comes into contact with the tilted guide stirring plate 232, it can tilt and move upward, thereby achieving the purpose of horizontal stirring and vertical tumbling.
