Hielscher

Hielscher Ultrasonics specializes in the design and manufacturing of high power ultrasonic homogenizers for lab, bench-top and production level. Ultrasonic power is an effective and energy-efficient means to apply high shear and intense stress to liquids, powder/liquid mixtures and slurries. This makes it a strong alternative to high shear mixers, high pressure homogenizers and agitated bead mills.

Hielscher ultrasonic devices are in use worldwide as laboratory mixers, high shear mixing equipment, full-size in-line homogenizers or particle mills. The applications include mixing, dispersing, particle size reduction, extraction and chemical reactions. We supply to various industry segments, such as nano-materials, paints & pigments, food & beverage, cosmetics, chemicals and fuels.

Scale-Up Capabilities
While the scale-up of a process from the laboratory or bench-top level to full production is the most critical and hardest step for other mixing technologies, it is most simple with Hielscher ultrasonic equipment. This is because; during scale up we do not change any of the driving parameters, such as amplitude or pressure. Ultrasonic batch mixing works well for volumes of up to 100L for some purposes, however ultrasonic in-line mixing using flow cell reactors and a feed pump is the more effective solution. In a flow cell the ultrasonic power is highly concentrated on a small volume resulting a more uniform processing and better product quality. A back pressure valve can be used to increase the pressure in the flow cell. This intensifies the sonication significantly resulting in higher hydraulic shear.
