100L ultrasonic herbal extraction equipment

advantages of equipment
Efficient extraction, reducing time by over 80%
Breaking the plant cell wall through cavitation effect accelerates the release of components.
For example, the extraction rate of ginkgo flavonoids increased from 56.5% in traditional methods to 91.6%, and the time was shortened from 6 hours to 30 minutes.
Low temperature protection thermal sensitive components
The entire process can operate at a low temperature of 40-80 ℃, avoiding high temperature damage to active ingredients such as volatile oils and alkaloids.
Energy-saving and environmental protection
Reduce energy consumption by 30% -50%, decrease solvent usage such as ethanol by 50%, and reduce waste liquid treatment costs by 70%.
Broad spectrum applicability

Compatible with various solvents such as water, ethanol, petroleum ether, etc., suitable for flavonoids (sophora rutin), alkaloids (berberine), polysaccharides (Cistanche deserticola) and other components

Equipment characteristics
Multi functional extraction tank
Structural design: Mushroom shaped tank body (large top and small bottom), equipped with PLC control system, made of 304 stainless steel material, supporting multiple modes such as dynamic counter current circulation and Soxhlet extraction.
Ultrasonic module: Single frequency, dual frequency or multi frequency ultrasound can be selected, with adjustable power (500W-3000W), suitable for different medicinal properties.
Integrated concentration system
Integrated design of extraction and concentration, reducing boiling point and retaining active ingredients through vacuum depressurization technology.
The condensation area (0.25-3.25m ²) and heating area can be flexibly configured, supporting small-scale testing to mass production (volume 5L-1000L).
technical advantage
Efficient and energy-saving: The extraction time is reduced by 50% -70% (such as berberine extraction only takes 30 minutes), and the yield is increased by 20% -40%.
Safety and Environmental Protection: Fully enclosed explosion-proof design, suitable for organic solvents such as ethanol, reducing volatilization losses

principle
The ultrasonic herbal extraction equipment utilizes the cavitation effect of ultrasonic waves (usually in the frequency range of 20-80kHz) to generate tiny bubbles in the solvent through high-frequency vibration and instantly rupture. The released energy can destroy the plant cell wall and accelerate the dissolution of active ingredients such as alkaloids, flavonoids, and essential oils. Combined with low-temperature vacuum concentration technology, concentration can be completed at 40-80 ℃ to avoid degradation of thermosensitive components

Detailed of process flow
Stage 1: Preprocessing and Extraction
Herbal treatment: Grind the raw materials to 20-60 mesh to increase the contact area.
Solvent immersion: Add solvent (such as water or ethanol) in proportion and soak at room temperature for 10-15 minutes.
Ultrasonic extraction:
Frequency range: 20-80kHz (adjustable), power density 0.5-1W/cm ².
Time: 20-40 minutes, synchronous mechanical stirring to prevent sedimentation.
Key mechanism: The rupture of cavitation bubbles generates micro jets (>100m/s) that flush the contents of cells.
Stage 2: Separation and Concentration
Solid liquid separation:
Built in dual filtration system (pore size 0.1-5 μ m) to intercept drug residues.
Vacuum low-temperature concentration:
Under a vacuum of -0.09MPa, evaporating water at 40-60 ℃ can increase the retention rate of thermosensitive components by 15-20%.
Solvent recovery:
The condensation system recovers organic solvents such as ethanol, with a recycling rate of 90%.
Technological innovation points:
Ultrasonic countercurrent circulation technology: The material is repeatedly passed through the ultrasonic probe, and the extraction rate is further increased by 40%.
Membrane separation integration: ultrafiltration/ceramic membrane further purification, impurity removal rate>95%
