Ultrasonic frequency is 2? 04 Hz~107 Hz which has exceeded the range of people can hear. When the ultrasonic transmits in the liquid, through mechanical, cavitate and heat function, it can produce mechanics, calorific, optics, electricity and chemistry reaction. Especially the high-power ultrasonic can produce strongly cavitate function, and then make the part form instantaneous high temperature, high voltage, vacuum and minute jet flow. For the chemistry, those cause a very good part small condition for reaction and improve reaction speed and reduce reaction condition. For biomass extract, those cause plant cell wall to break and liquid to immerse quickly, and make the extracted active principle can dissolve into the liquid quickly. This will improve rate of exaction, reduce time of exaction and save liquid. Ultrasonic apply in biomass source processing is a hot spot of research and explore in recent year. The most representative working is ultrasonic apply in extracting plant active principle and bio diesel equipment. Ultrasonic exaction frequency range is 15kKHz~100KHz, about frequency 20KHz ultrasonic is used mostly. One reason is the ultrasonic frequency lower, the power is larger. Some one think this frequency is helpful for breaking the plant cell wall.

Basic structure:
1. Ultrasonic focusing probe type ultrasonic exaction system
Basic structure: Oscillator system includes transducer, booster, horn (probe) and generator
Characteristic: The processed liquid need put into the container, and put the horn into the liquid, and then transmit ultrasonic. The liquid flow in the container, and be effected by the strongly ultrasonic. The processed liquid volume can large or small. In general, for same size container, liquid flow smaller is, its stop time is longer in the container, ultrasonic function time is longer. Contrarily, controlling ultrasonic function time shorter is, the production is higher.

Main technology:
1. Frequency range: 15KHz to 60 KHz
2. One unit marked power: 500W\1000W\1500W\2000W\3000W. The lower frequency is, the larger per unite power will be; The higher frequency is, the lower per unite power will be. Can be used many unites assembled.
3. Horn (probe) material: Stainless steel, titanium alloy. Also can be made according to requirements.
4. Container: Suggest use diameter 100mm to diameter 1000mm. Diameter is larger, the production is larger. But unit area Ultrasonic power is smaller. The container can be made by yourself, also lest us do for you.
5. Production: 10kg/h ~ 1000kg/h, the production can be larger through assembled.
6. Generator: Analog generator, digital generator, frequency automatic tracking, overcurrent and overvoltage protection, power can be ajusted
