Description

Technical Field

[0001] The present application relates to the technical field of concentration and extraction, and more specifically, to a wall-breaking hot reflux ultrasonic extraction and concentration device. Background Art

[0002] The extraction of effective components of plant materials has traditionally relied on solvent extraction, which is achieved through solvent immersion at a precise solid-liquid ratio and a suitable temperature. In order to optimize the extraction efficiency, auxiliary means such as stirring, circulation, constant temperature control and solvent reflux are often used. In recent years, ultrasonic technology has attracted much attention due to the mechanical, cavitation and thermal effects it produces in the solvent. It can effectively destroy plant cell walls, accelerate solvent penetration, significantly improve extraction efficiency and speed, and save solvent at the same time. Among them, cavitation comprehensively enhances the mass transfer process and accelerates the release of effective components through turbulence, perturbation, interface and energy focusing effects. Hot reflux ultrasonic extraction and concentration equipment usually includes main components such as vacuum concentration tanks, extraction tanks and solvent recovery tanks. However, existing ultrasonic extraction devices still face the challenges of low efficiency and incomplete crushing. There is an urgent need to develop a new efficient and rapid ultrasonic concentration and extraction technology to further improve the extraction efficiency of effective components of plant materials. Utility Model Content

[0003] To this end, the utility model provides a wall-breaking hot reflux ultrasonic extraction and concentration device to overcome the problems of low efficiency and incomplete crushing in the prior art of ultrasonic wall-breaking extraction.

[0004] In order to achieve the above-mentioned purpose, the present invention provides a wall-breaking hot reflux ultrasonic extraction and concentration equipment, including a vacuum concentration tank, an extraction tank and a solvent recovery tank, wherein the extraction tank includes a tank body, an ultrasonic generator and a stirring assembly.

The ultrasonic generator is installed at the center of the top of the tank body, and the ultrasonic generator is used to crush the extract. The stirring assembly is installed on the tank body, and the stirring assembly is used to stir the extract. The stirring assembly includes a first stirrer and a second stirrer. The first stirrer is installed at the bottom of the tank body, and the first stirrer is located directly below the ultrasonic generator. When the first stirrer is started, the extract near the ultrasonic generator moves upward or downward. There are three second stirrers, which are installed on the tank body. The three second stirrers are evenly spaced and arranged around the first stirrer. When the second stirrer is started, the extract near the inner wall of the tank moves upward or downward.

[0005] In certain embodiments, the extraction tank further includes an electric controller, and the electric controller is used to control the first agitator and the second agitator.

[0006] In some embodiments, the first agitator includes a first motor and a stirring blade, the first motor is installed at the bottom of the tank, and the stirring blade is installed on the output shaft of the first motor.

[0007] In some embodiments, the second agitator includes a second motor, a rotating shaft and a spiral blade, the second motor is installed on the top of the tank body, the spiral blade surrounds the outer circumference of the rotating shaft, the two ends of the rotating shaft are respectively installed at the bottom and top of the tank body, and the top end of the rotating shaft is connected to the output shaft of the second motor.

[0008] In some embodiments, the cross-sectional radius of the stirring blade is equal to the cross-sectional radius of the spiral blade.

[0021] See also Figure 1 The wall-breaking hot reflux ultrasonic extraction and concentration equipment 100 provided by the present invention includes a vacuum concentration tank (not shown), a solvent recovery tank (not shown) and an extraction tank 10. The extraction tank 10 includes a tank body 11, an ultrasonic generator 12 and a stirring assembly 13. The tank body 11 is cylindrical and is used to hold the extract. The ultrasonic generator 12 is installed at the center of the top of the tank body 11. The ultrasonic generator 12 is used to crush the extract. The stirring assembly 13 is installed on the tank body 11. The stirring assembly 13 is used to stir the extract. The stirring assembly 13 includes a first stirrer 131 and a second stirrer 132. The first stirrer 131 is installed at the bottom of the tank body 11. The first stirrer 131 is located directly below the ultrasonic generator 12. Starting the first stirrer 131 causes the extract close to the ultrasonic generator 12 to move upward or downward. There are three second agitators 132 installed on the tank body 11. The three second agitators 132 are evenly spaced and arranged around the first agitator 131. When the second agitators 132 are started, the extract close to the inner wall of the tank body 11 moves upward or downward.

[0022] The wall-breaking hot reflux ultrasonic extraction and concentration equipment 100 of the present application sets the first agitator 131 directly below the ultrasonic generator 12. Its stirring action can directly drive the extract in the ultrasonic action area to move up and down, effectively promoting the dissolution and release of the effective ingredients in this area. The three second agitators 132 are evenly spaced around the first agitator 131. Their stirring action can drive the extract near the inner wall of the tank body 11 to move, avoiding the sedimentation and retention of the extract at the edge of the tank body 11, thereby ensuring the full crushing and mixing of the extract in the entire tank body 11, solving the problems of low efficiency and incomplete crushing in the wall-breaking hot reflux ultrasonic extraction process.

[0023] Specifically, the extraction tank 10 further includes an electronic controller 14 for controlling the first agitator 131 and the second agitators 132. The electronic controller 14 can be mounted on the tank body 11 or elsewhere, as needed. The electronic controller 14 controls the first agitator 131 and the three second agitators 132 so that they can operate independently.

[0024] In certain embodiments, the first agitator 131 includes a first motor 1311 and a stirring blade 1312. The first motor 1311 is mounted at the bottom of the tank 11, and the stirring blade 1312 is mounted on the output shaft of the first motor 1311. Specifically, the first motor 1311 is connected to the electronic controller 14. The stirring blade 1312 has three blades. When the electronic controller 14 activates the first motor 1311 to rotate clockwise, the extract moves upward, while simultaneously gathering the extract around the stirring blade 1312 and drawing it closer to the ultrasonic generator 12. When the first motor 1311 is activated to rotate counterclockwise, the extract moves downward, while simultaneously causing the extract in the center to diffuse toward the extract around the stirring blade 1312.

[0025] In some embodiments, the second agitator 132 includes a second motor 1321, a rotating shaft 1322 and a spiral blade 1323. The second motor 1321 is installed on the top of the tank body 11, and the two ends of the rotating shaft 1322 are respectively installed at the bottom and top of the tank body 11. The spiral blade 1323 surrounds the outer circumference of the rotating shaft 1322, and the top of the rotating shaft 1322 is connected to the output shaft of the second motor 1321.

[0026] Specifically, the angle formed by the center of the first agitator 131 and the line connecting the centers of any two second agitators 132 is 120 degrees, and the centers of the three second agitators 132 are on the same circle centered on the center of the first agitator 131. This ensures that when the second motor 1321 is operating, the tank body 11 can maintain balance and avoid excessive shaking.

[0027] The electronic controller 14 is connected to the three second motors 1321 and controls them separately. The electronic controller 14 starts the second motors 1321 to drive the spiral blades 1323 on the rotating shaft 1322 to rotate. When the second motor 1321 rotates clockwise, the extract moves downward; when the second motor 1321 rotates counterclockwise, the extract moves upward. By driving the spiral blades 1323 on the rotating shaft 1322 to rotate by the second motor 1321, the extract near the inner wall of the tank body 11 can move up and down or approach the ultrasonic generator 12. At the same time, combined with the use of the first agitator 131, a backflow is formed inside the tank body 11, which can achieve full stirring of the extract in the entire tank body 11, avoiding the situation where only the extract near the ultrasonic generator 12 can be broken, while the extract near the inner wall of the tank body 11 cannot be fully broken.

[0028] In some embodiments, in order to enable stirring at different rotation speeds while the tank body 11 can still remain relatively stable, the cross-sectional radius of the stirring blade 1312 is equal to the radius of the rotating shaft 1322 .

[0029] In some embodiments, the speed ratio of the first stirrer 131 to the second stirrer 132 is 3:1. Specifically, the electronic controller 14 of the present application is provided with four option programs: fast, medium, slow, and custom. Customization can set the three speeds of fast, medium, and slow. The staff can set different speeds according to different materials. The electronic controller 14 is provided with default speeds of fast, medium, and slow:

[0030] Fast: the first motor 1311 rotates at 45 rpm, and the second motor 1321 rotates at 15 rpm;

[0031] Medium speed: the first motor 1311 rotates at 30 rpm, and the second motor 1321 rotates at 10 rpm;

[0032] Slow speed: the first motor 1311 rotates at 9 rpm, and the second motor 1321 rotates at 3 rpm.

[0033] In one example, a worker needs to stir the extract at a slow speed. At this time, the first motor 1311 rotates at 9 rpm, and the three second motors 1321 rotate at 3 rpm.

[0034] In some embodiments, the top of the tank body 11 is provided with an inlet 111, and the bottom of the tank body 11 is provided with an outlet 112. The outlet 112 is provided with a transition notch 1121 to facilitate the discharge of the extract. Specifically, the transition notch 1121 is in the shape of a conical funnel and is lower than the inner wall of the bottom of the tank body 11, facilitating the discharge of the extract.
