High Power Sonicator Ultrasonic Processor , 20Khz Sonicator Lab Equipment

Description

Ultrasonic mixing equipment is a device that uses ultrasonic technology to mix liquids or solids. The equipment can effectively break the boundaries between substances and achieve efficient and uniform mixing through the cavitation effect and mechanical force generated by ultrasonic vibration. Ultrasonic mixing equipment is widely used in chemical, pharmaceutical, food, cosmetics and other industries. Especially in the mixing process that requires high uniformity and high efficiency, ultrasonic mixing equipment can provide unique advantages.

Working principle of ultrasonic mixing

Ultrasonic transducer: The core component of ultrasonic mixing equipment is the ultrasonic transducer (or ultrasonic probe), which converts electrical energy into mechanical vibrations and transmits it through the liquid. The transducer generates high-intensity sound waves by vibrating at ultrasonic frequencies (usually between 20kHz and 100kHz).

Cavitation effect: In liquids, ultrasonic vibrations cause alternations of local high and low pressures, which in turn produce tiny bubbles. These bubbles expand rapidly under pressure and eventually collapse, a process called cavitation. The cavitation effect can produce strong shear forces and local high temperatures, which can effectively destroy the particles or material structures in the liquid.

Shear force and strong stirring: The shear force caused by the cavitation effect and the impact of tiny bubbles enable the substances in the liquid to be quickly and evenly dispersed or mixed. Solid particles, droplets, bubbles, etc. in the liquid will be quickly broken up, thereby achieving uniform mixing.

Efficient transmission: The frequency and energy of ultrasound can be adjusted as needed, so the intensity, speed and duration of the mixing process can be precisely controlled. Compared with traditional mechanical stirring, ultrasonic mixing equipment can achieve a more uniform mixing effect in a shorter time.
