Ultrasonic Liquid Processing System
Ultrasonic sonochemistry is caused by cavitation phenomenon. In chemistry, cavitation refers to the formation, growth, and implosion of tiny bubbles. Cavitation bubbles are composed of a cycle of compression to expansion. When ultrasound passes through a liquid, it continuously compresses and expands it. High intensity ultrasound provides the energy required to disperse the liquid phase. When the maximum pressure is reached, liquid rupture occurs at the point of weaker cohesion. After this rupture, overpressure appeared at the point of rupture and some cavities were found. In these voids, gas dissolved in liquid explodes in the form of bubbles after a short period of time. During bubble rupture, a very high pressure is generated, approximately 1000 atmospheres. Ultrasonic treatment can generate extreme physical and chemical conditions in liquids, which can be applied in extraction, crushing and mixing, emulsification, dispersion and stirring, defoaming and degassing, etc.
Extraction
Ultrasonic extraction is a technique that uses high-frequency ultrasound to separate and extract substances. Ultrasonic extraction generates ultrasonic pulses with a frequency of over 20kHz through high-frequency oscillation, which causes rapid mechanical vibration of solvent molecules, thereby increasing the diffusion and dissolution ability of the solvent. Ultrasonic waves break down the cell wall and membrane, releasing valuable components inside the cell while disrupting the interactions between compounds, improving their solubility and extraction efficiency. After a certain period of ultrasonic radiation, the desired compound or active ingredient can be extracted
Dispersion
Ultrasonic dispersion system is a technology that uses high-frequency sound waves (usually above 20kHz) to achieve fine dispersion of substances. It is widely used in the chemical industry for processes such as emulsification, suspension dispersion, and degassing. Stable dispersion of pigments, coatings, and inks; Food industry: used for fine dispersion of protein, starch and other raw materials to improve texture and taste; Pharmaceutical industry: used for the preparation and dispersion of drugs, medical capsules, etc; Material processing: dispersion treatment of powder materials such as metals and ceramics to improve reaction activity and sintering properties; Environmental governance: dispersion removal in sewage treatment and exhaust gas treatment.
Emulsification
Ultrasonic emulsification is a technique that uses high-frequency ultrasonic energy to break the molecular structure of liquid or solid substances and form an emulsion. This method is usually used to prepare emulsions, suspensions, sprays and other products.
Ultrasonic emulsification technology is widely used in industries such as cosmetics, pharmaceuticals, food, coatings, etc. It has the advantages of simple operation, low energy consumption, fine product particles, and good emulsion stability. With the further development of technology, ultrasonic emulsification has been increasingly applied in fields such as new material preparation and biomedicine.
Degassing
Ultrasonic degassing treatment is a method that utilizes the physical properties of ultrasound to generate micro jets, high-energy regions, and acoustic pressure waves in liquids, causing bubbles in the liquid to rapidly rupture and release gas, thereby achieving the purpose of defoaming and degassing.
Ultrasonic degassing treatment is mainly applied to: petroleum industry: eliminate foam generated in the process of oil and gas separation, improve oil and gas recovery and production efficiency; Chemical industry: eliminate foam in reaction kettle and pipeline, improve product yield and quality; Pharmaceutical industry: eliminate foam in the production process of drug solutions, improve the purity and concentration of drug solutions; Food industry: eliminate foam during fermentation, and improve the taste and quality of food.
Cell Disruption
Ultrasonic cell disruptor, also known as ultrasonic microwave synergistic extraction instrument, ultrasonic cell lysis instrument, and ultrasonic nano material pulverizer. Ultrasonic cell disruptor utilizes the dispersion effect of ultrasound in liquid to generate cavitation, thereby breaking solid particles or cell tissues in the liquid.
Ultrasonic pulverizers can be used to pulverize animal cells, plant cells, bacteria, dental spores, or tissues. Disperse rare earth and various inorganic mineral powders; It can also accelerate the reaction speed of chemistry, biology, and physics, and is an ideal device for accelerating liquid degassing; At the same time, it can be configured with latex particles that are almost one hundredth of a micrometer in size; Homogenize the "difficult to mix" mixture; Aggregate some substances and precipitate others.
