Description

Ultrasonic and microwave synergistic extraction device and method combined with turbulence effect

technical field

The invention relates to an ultrasonic and microwave synergistic extraction device and method combined with turbulence effect.

Background technique

Plants contain many nutrients and even some functional ingredients. If they can be extracted and utilized in a relatively complete and efficient manner, they can be used in a wide range of industries, such as pharmaceutical, food, health care and biochemical industries. However, traditional extraction methods, such as cooking, seepage and other methods, have low extraction efficiency.

At present, there are many methods based on microwaves or ultrasonic waves to extract plant functional components, which are more efficient than traditional extraction methods. However, in order to improve the extraction efficiency of components, it is necessary to crush the material as finely as possible and increase the amount of solvent used. Too fine slurry is not easy to separate, which makes the subsequent separation process difficult to operate, and it is easy to cause filter blockage, overflow, etc. However, there is still no high extraction efficiency.

Contents of the invention

In order to solve the above problems, the present invention proposes an ultrasonic and microwave synergistic extraction device and method combined with turbulent flow effects. The present invention utilizes the cooperation of turbulent flow effects and double waves (ultrasonic waves, microwaves) to efficiently extract functional components, and combined with reflux Rinse, so that the mixed material quickly flows out of the extraction tank and enters the filtrate funnel for temporary storage, and squeezes the slag to maximize the liquid. Thereby the extraction efficiency is further improved.

In order to achieve the above object, the present invention adopts the following technical solutions:

An ultrasonic and microwave synergistic extraction device combined with turbulent flow effects, including a reactor, a separator, and a reflux flushing mechanism, wherein the reactor uses ultrasonic waves and microwaves to perform synergistic effects on materials, and a turbulent flow generating device is installed in the reactor. The turbulence effect generated by the turbulent flow generating device makes the effect of ultrasonic and microwave uniform, and the reacted mixture enters the separator, and the separator is connected with a reflux flushing mechanism, and the reflux flushing mechanism returns the separated solution to the reactor.

Utilizing the ultrasonic generator and the microwave generator at the same time, the microwave has the characteristic of selective heating. When the microwave acts on the material, the liquid in the cell is preferentially heated, the temperature in the cell rises rapidly, the inside of the cell is heated and expands, and the structure of the cell membrane phospholipid bilayer is destroyed. When the intracellular pressure exceeds the pressure of the cell membrane, the cell membrane ruptures and the cell The useful components flow out, and the extraction effect can already be achieved under the action of microwave, which improves the extraction efficiency. Ultrasound can break through the cell wall or cell membrane through oscillating energy, and can be superimposed with microwave. After superimposing ultrasonic waves, the effect is better, which improves the extraction speed and the output of the extract.

Further, the turbulent flow generating mechanism includes a turbulent flow generating rod and a motor, and the motor drives the turbulent flow generating rod to rotate. The setting of the turbulence generating rod makes the surface hydration film formed by the extract raw material and the extraction solvent in the reactor quickly detach from the surface of the raw material, which accelerates the diffusion of the extracted components and improves the extraction speed. The effect of the agent is sufficient, so that the effect of microwave and ultrasonic is more uniform.

Further, the turbulence generating rod has an included angle with respect to the central axis of the extraction tank.

Preferably, the included angle is 30°-60°. The most preferred solution is 45°. The inclined setting of the turbulence generating rod makes the effect of turbulence generation more sufficient and complete, and at the same time, the contact surface with the material is larger.

These settings can make the turbulence effect more sufficient and complete, and ensure that the material is more uniform in the process of microwave and ultrasonic reactions.

Further, the separator includes a filtrate funnel, a screw extruder and a liquid storage tank, the screw extruder is arranged at the lower end of the filtrate funnel, the slag of the filtrate funnel is sent to the screw extruder for extrusion, and the filtrate is sent to Reservoir for storage. As the slag in the filtrate funnel increases, the slag is gradually brought into the screw extruder, and the slag is extruded by the screw extruder, and the useful components in the slag are further squeezed out. The useful components flow into the liquid storage tank, and the remaining waste materials are discharged through the waste material outlet. The extraction efficiency is further improved.

Further, a plurality of filtrate holes are opened on the side of the filtrate funnel, the filtrate flows into the liquid storage tank through the filtrate holes, and the remaining residue remains in the filtrate funnel.

Further, the shell of the screw extruder is provided with many small holes, and the extruded liquid useful components flow into the liquid storage tank along with the small holes.

Further, the reflux flushing mechanism includes a reflux pump and a reflux flushing pipe. The reflux pump is arranged outside the liquid storage tank to return the filtrate in the liquid storage tank to the extraction tank through the reflux flushing pipe. Combined with reflux pressure, etc., the mixture in the extraction tank is flushed. Such an arrangement can speed up the flow of the mixed material in the extraction tank into the filtrate funnel of the separator through the feed opening, and effectively prevent the feed opening from being blocked.

An ultrasonic and microwave synergistic extraction method combined with turbulence effect, using ultrasonic and microwave to synergistically act on materials and extractants, using turbulent effect to homogenize the effects of ultrasonic and microwave, extracting material components, and reacting the mixed material for solid-liquid extraction Separation, and the solution obtained after the separation is refluxed again to flush the reacted mixture.

The extraction effect can already be achieved under the action of microwave, and after superimposition of ultrasonic wave, the energy of ultrasonic oscillation can destroy the cell membrane or cell wall, and the extraction effect is even better;

(2) While reacting, use a turbulence generating device to generate turbulent flow between the material and the extractant to ensure a larger contact surface of the material, so that the hydration film formed on the surface of the material and the solvent is quickly detached, accelerating the diffusion of active ingredients, while avoiding the mixture Adverse effects caused by excessive local heating, the extraction rate of useful components is higher;

(3) Set the filtrate funnel to cooperate with the screw extruder to quickly make the slag enter the filtrate hopper, and the slag is gradually brought into the screw extruder, and the slag is squeezed by the screw extruder. The useful components in it are further squeezed out and recycled; at the same time, the useful components flow into the liquid storage tank, and the remaining waste is discharged through the waste outlet, which further improves the extraction efficiency;

(4) A reflux flushing mechanism is provided, which can accelerate the flow of the mixed material in the extraction tank into the filtrate funnel of the separator through the feeding opening, and effectively prevent the blocking of the feeding opening.
