The propagation of the target flowmeter in the medium can make the medium particle vibrate in its propagation room space, and then strengthen the external diffusion and propagation of the medium, which is the mechanical equipment effect of ultrasonic. In the process of ultrasonic propagation, it causes a kind of radiation source gas pressure, which propagates along the frequency direction of the sound wave. It has a strong destructive effect on the raw materials, can make the body cells and tissues deform, and the green plant protein hydrolyze. In addition, it can give different instantaneous speed to the medium and the floating body, and the fitness movement speed of the medium molecular structure is much faster than that of the floating body molecular structure Dynamic rate. This kind of sliding friction can depolymerize the biomolecule and make the effective components on the cell wall dissolve in the organic solvent rapidly.
In general, some micro bubbles are melted in the problem of target flowmeter, which vibrate under the effect of ultrasonic. When the sound intensity reaches a certain value, the bubbles expand due to the corrected diffusion, resulting in a common shock cavity, and then suddenly close, which is the cavitation effect of ultrasonic. This kind of bubble creates hundreds of working pressure of atmospheric pressure around it when it is closed, and generates micro shock wave. It can cause the cell wall of plant and all plant bodies to crack, and the whole process of cracking is carried out in a moment, which is beneficial to the total mixing of effective components.
In addition, ultrasound can cause many secondary coil effects, such as emulsion, external diffusion, destruction, organic chemical effects, etc., which also promote the dissolution of effective ingredients in plant cells, promote the effective ingredients of therapeutic drugs into the medium, and mix them in the medium sufficiently, accelerate the acquisition process, and develop the acquisition rate of effective ingredients of therapeutic drugs. Like other physical waves, the propagation process of ultrasonic wave in the medium is also a process of kinetic energy propagation and external diffusion, that is, during the propagation process of ultrasonic wave in the medium, its sound is continuously digested and absorbed by the particles in the medium, and the medium will convert all or large units of digested and absorbed kinetic energy into energy, thus causing The increase of the temperature of the medium itself and the mechanism of traditional Chinese medicine enlarges the dissolution rate of the effective components of the therapeutic drugs. Since the temperature rise in the therapeutic drug mechanism caused by such digestion and absorption of sound is instantaneous, the biological activity of the obtained components can be maintained unchanged.
Characteristics of ultrasonic acquisition
It can prevent the negative effects of long-term heating of traditional Chinese medicine, such as basic decocting method and flowing back method, on the effective ingredients, and can be used to obtain the thermistor chemicals. In addition, it does not need heating, so it also saves power energy.
Ultrasonic acquisition develops the acquisition rate of effective ingredients of therapeutic drugs, saves raw materials of traditional Chinese medicine, is beneficial to the flexible use of traditional Chinese medicine resources, and develops economic benefits.
The use of organic solvent is less, and the organic solvent is saved.
Ultrasound acquisition is a physical process. There is no chemical change in the whole extraction process, and it does not harm the physiological specificity of most of the effective components of therapeutic drugs.
The effective components of the extract are high, which is beneficial for further preparation
