20khz Lab Ultrasonic Extraction System

YP-S59 20Khz Ultrasonic Dispersing machine(Lab Level)

When sonicating liquids the sound waves that propagate into the liquid media result in alternating high-pressure (compression) and low-pressure (rarefaction) cycles. This applies mechanical stress on the attracting electrostatic forces. Ultrasonic cavitation in liquids causes high speed liquid jets of up to 1000km/h (approx. 600mph). Such jets press liquid at high pressure between the particles and separate them from each other. Smaller particles are accelerated with the liquid jets and collide at high speeds. This makes ultrasound an effective means for the dispersing and deagglomeration, but also for the milling and fine gringding of micron-size and sub micro-size particles. 

Advantage:

1.Save dispersing time 20%~60%

2.Lower temps 30%~60%(30 degrees C)

3. easily to do installation

4. operation in high efficience

5. digital generator V6.0 surpporting the system ; searching frequency automatically

Parameter 

Ultrasound of the transesterification reaction mechanism is based on cavitation.

In the ultrasonic irradiation, the liquid flow generated thousands of tiny bubbles, these tiny air bubbles vibrate in the effect of sound field, when the sound pressure reaches a certain value, the bubble rapidly growth, then bubbles burst and generated the burst wave, so that atmospheric pressure is generated around the thousands.

Radiation input energy is converted into frictional, waves and cavitation, cavitation bubbles burst of negative pressure can produce intense local high temperature ( about 5000K) and high pressure ( about 100Mpa), accompanied by a huge cooling rate ( greater than 109K / S) and the liquid jet stream ( about 400Km / h), and the agitation caused by the pressure of liquid can overcome the adhesion force and the adhesive force to the reaction system in a very short period of time to achieve better dispersing.
