3000 Watt Ultrasonıc Homogenızer

When ultrasonic homogenizers are used for applications such as mixing, dispersing and emulsifying, the aim is to reduce small particles or droplets in a liquid or slurry to increase the homogeneity and stability of the mixture. These particles (disperse phase) can be solid or liquid. A decrease in the mean diameter of the particles increases the number of individual particles. This leads to a decrease in the average particle distance and increases the particle surface area. Surface area and mean particle distance can affect the rheology of a liquid. If there is a difference in specific gravity between the particles and the liquid, the homogeneity of the mixture can affect the stability of the dispersion. If the particle size is similar for the majority of the particles, the tendency to agglomerate during settling or rise is reduced because similar particles have a similar rise or settling rate.

The most common mechanism for homogenization is high pressure homogenization. Here, the liquid is pressed at high pressure (approximately 2000 barg) via a homogenizing valve. As it passes the valve, the fluid undergoes a short (about 50 microseconds) high pressure low pressure cycle. Although this mechanism works well for small, soft particles such as fat globules in milk, it has limitations when used for pigments, polishing medium or dispersions of metal oxides or hard and abrasive materials. fruit purees, moss or mud. This is due to the high liquid velocities (up to 120mtr/s) and the small orifices of the valves used. Abrasive material causes wear as it passes the pumps and valve opening. This reduces the efficiency and life of the pump and valve.
