The ultrasonic herbal extraction equipment utilizes the mechanical, cavitation, and thermal effects of ultrasound to extract bioactive components by increasing the velocity and penetration of medium molecules.

Mechanical effect
The propagation of ultrasonic waves in a medium can cause vibration of medium particles in their propagation space, thereby enhancing the diffusion and propagation of the medium. This is the mechanical effect of ultrasonic waves. Ultrasonic waves generate a radiation pressure during propagation, which propagates along the direction of sound waves and has a strong destructive effect on materials, causing deformation of cell tissues and denaturation of plant proteins; At the same time, it can also provide different accelerations to the medium and suspension, and the velocity of the medium molecules is much higher than that of the suspension molecules. Thus, friction is generated between the two, which can cause biomolecules to dissociate and dissolve the active ingredients on the cell wall faster in the solvent.
Cavitation effect
Under normal circumstances, some microbubbles are more or less dissolved inside the medium, and these bubbles vibrate under the action of ultrasound. When the sound pressure reaches a certain value, the bubbles increase due to directional diffusion, forming a resonant cavity, and then suddenly closing, which is the cavitation effect of ultrasound. When this type of bubble closes, it generates thousands of atmospheres of pressure around it, forming micro shock waves that can cause the rupture of plant cell walls and the entire organism. The entire rupture process is completed in an instant, which is beneficial for the dissolution of active ingredients.
thermal effect

Like other physical waves, the propagation of ultrasound in a medium is also a process of energy propagation and diffusion. That is, during the propagation of ultrasound in a medium, its sound energy is continuously absorbed by the particles of the medium, and the medium converts all or most of the absorbed energy into thermal energy, resulting in an increase in the temperature of the medium itself and the medicinal tissue, and an increase in the dissolution rate of the active ingredients. Due to the instantaneous increase in internal temperature caused by the absorption of sound energy, the biological activity of the extracted components can be maintained unchanged.

Comparison of Extraction Efficiency: Compared to traditional decoction methods, ultrasonic extraction can shorten the extraction time from 6-12 hours to 30-90 minutes, increase extraction efficiency by 3-5 times, and reduce solvent usage by more than 50%.

2、 Vacuum concentration stage: rapid dissolution at low temperature
The extracted liquid phase contains a large amount of solvents (such as water and ethanol), which need to be concentrated to reduce the solvent content and increase the concentration of active ingredients. The core of vacuum concentration is to utilize the characteristic of reducing the boiling point of solvents in a vacuum environment to achieve rapid dissolution at low temperatures. The specific process is as follows:
Vacuum depressurization (lowering boiling point)
In a vacuum state (pressure 0.01-0.08MPa), the boiling point of the solvent significantly decreases (for example, ethanol has a boiling point of 78 ℃ at atmospheric pressure and drops to 35 ℃ at 0.05MPa); The boiling point of water at atmospheric pressure is 100 ℃, and its boiling point drops to 45 ℃ at 0.05MPa. This allows the concentration process to be carried out at low temperatures (40-60 ℃), avoiding the degradation of heat sensitive components such as ginkgo flavonoids and tanshinone due to high temperatures.
Thin film evaporation (efficient mass transfer)
The extraction liquid enters the concentration tank through a scraper or falling film device, forming a thin layer (thickness 1-2mm) on the heating tube wall to increase the evaporation area; At the same time, vacuum suction rapidly vaporizes the solvent, which is recovered by the condenser (solvent recovery rate ≥ 95%), and the concentrated solution (effective ingredient concentration increased by 5-10 times) is discharged from the bottom.
Temperature control and anti coking (ensuring quality)
The equipment is equipped with a PID temperature control system, which accurately controls the heating temperature (± 1 ℃) to avoid local overheating; The scraper device can continuously stir the concentrated solution to prevent high viscosity materials (such as ass hide glue and honey) from adhering to the pipe wall and coking.

Comparison of Concentration Efficiency: Compared to single effect evaporators, vacuum concentration reduces energy consumption by 50% -70%, shortens concentration time to 1-2 hours, and increases product purity by 10% -20%.
