The ultrasonic homogenizer relies on the acoustic cavitation effect of ultrasonic treatment. When the equipment is running, the ultrasonic wave propagates in the liquid medium of the material system, resulting in an alternating area of high and low pressure. In the low pressure area, tiny bubbles form rapidly, and in the high pressure area, the bubbles collapse violently, releasing huge energy and forming strong shock waves and high-speed microjets. These powerful forces can break and disperse the aggregate in the material, promote the uniform distribution of the material in the system, and achieve the effect of homogenization.
In the production of sauces, beverages and other foods, the ultrasonic homogenizer can refine the particles or droplets in the raw materials to make the material mix more evenly. In jam production, for example, the pulp particles can be evenly dispersed, improve taste, enhance product stability, and prevent precipitation or delamination.
In the preparation of suspension and emulsion drugs, the ultrasonic homogenizer can make the active ingredients of drugs evenly dispersed in the carrier, ensure the accurate dose of drugs, improve the stability and bioavailability of drugs.
In the production process of paint and ink, the ultrasonic homogenizer can evenly disperse pigments and fillers in the base material, improve the quality and stability of the product, and avoid problems such as uneven color and precipitation.
Ultrasonic homogenization has high efficiency, and can achieve the homogenization of materials in a shorter time than the traditional stirring homogenization method. Good homogenization effect, particles or droplets can be refined to nanometer or micron level, to achieve a high degree of uniform dispersion; The operation is relatively simple, the equipment is easy to control, and it is easy to realize automatic production.
The energy consumption of ultrasonic equipment is large, the energy utilization efficiency needs to be improved, and the production cost will be increased in large-scale application. It is difficult to guarantee the uniformity of ultrasonic field, which may lead to the difference of homogenizing effect. The high temperature and high pressure generated by acoustic cavitation may cause damage to some heat-sensitive or easily oxidized materials.
