Ultrasonic Assisted Liquid Processors
What's the theory of ultrasonic sonochemistry?
The essence of the sonochemical effect is the cavitation effect, including the appearance of the gas nucleus, the growth of the microbubbles and the bursting of the microbubbles. Under the action of ultrasound, the fluid produces a sharp motion. Due to the change of sound pressure, the solvent is compressed and sparse. In the sparse phase region of the sound wave, the gas bubble expands and is filled with the surrounding liquid vapor or gas. In the compressed phase region, the air pockets quickly collapse and rupture, producing a large number of microbubbles, which in turn can serve as new gas cores. It is currently believed that the main reason for the influence of ultrasound on chemical reactions is that these microbubbles can generate strong shock waves when they grow up and suddenly rupture. It is estimated that when the microbubble bursts, it can generate pressures up to MPa in the local space, and the center temperature can reach 3000-5000K. The interpretation of the action of the ultrasonic field has not yet entered the molecular level, but stays in the machinery of the molecular group. The level of action mechanism. For example, the cavitation and cleansing effect on the solid surface; the emulsification of the immiscible liquid; the effect of the high temperature and high pressure caused by the shock wave in the micro space on mass transfer and energy transfer when the microbubble bursts.

Advantages of Ultrasonic Extraction
1. Ultra-high extraction efficiency, short processing cycle
Powerful ultrasonic cavitation generates instant micro-jets, shock waves and shear force to break plant cell walls rapidly. Active ingredients can be fully released within minutes or dozens of minutes, while traditional heat reflux/maceration takes several hours or even days. It greatly boosts workshop throughput and shortens production lead time.
2. Low-temperature extraction, well retain thermosensitive active substances
The whole extraction process runs under normal temperature without high-temperature heating. It avoids oxidation, decomposition and failure of heat-sensitive components such as plant essential oils, flavonoids, polyphenols, vitamins and natural pigments, ensuring higher activity and better quality of final extracts.
3. Lower solvent consumption & cost saving
Strong cavitation penetration fully separates target components from raw materials, requiring far less ethanol, water and other organic extraction solvents compared with traditional soaking methods. It cuts raw material procurement costs and reduces follow-up solvent recovery workload.
4. High extraction yield, fully utilize raw materials
Ultrasonic vibration penetrates solid raw materials thoroughly, extracting more effective substances that are hard to separate via conventional processes. It significantly improves the extraction rate of herbs, seeds, fruits and algae, maximizing the utilization rate of raw materials and reducing material waste.
5. Wide material compatibility
Applicable to all kinds of raw materials: Chinese medicinal herbs, plants, flowers, fruits, algae, animal tissues, spices, natural pigments and functional food raw materials. Works with aqueous phase, alcohol and other organic solvent systems.
6. Energy-saving & low operating cost
No continuous heating system required; the ultrasonic generator consumes much less electricity than thermal reflux extraction equipment. The titanium alloy sonotrode features long service life, low wear and few replacement parts, lowering long-term production maintenance expenses.
7. Simple operation, easy industrial scale-up
Supports intermittent tank immersion extraction and inline continuous pipeline production, easy to connect with reaction kettles, concentration and filtration equipment to form an automated production line. Parameters like power, time and amplitude are digitally adjustable for stable repeatable extraction results in mass production.
8. Clean extraction, eco-friendly
Short extraction time reduces solvent volatilization loss. When matched with explosion-proof ultrasonic units, it can safely handle flammable alcohol solvents, lowering workshop VOC emissions and meeting environmental protection standards for pharmaceutical, food and cosmetic factories.
9. Less impurity content in extract
Mechanical shock from ultrasound only releases intracellular target ingredients without dissolving a large amount of macromolecular impurities such as starch and pectin. The crude extract has fewer impurities, simplifying subsequent filtration, purification and separation procedures.
