It is widely used in the fields of ultrasonic cleaning, biochemistry, food, chemical and pharmaceutical industry. In biochemistry industry, the tubular transducer equipment can be used for emulsification, separation, homogenization, refining and catalyzing reaction and it can increase production capacity. The tubular transducer equipment plays an important role in the even stirring of homogenates in food processing. In the chemical industry, it is suitable for cleaning pipeline, tanks and kettles. The catalyzing effect of ultrasonic is quite obvious when the tubular transducer equipment used in the refinement of scavenge oil and palm oil to biodiesel, as the efficiency can be improved more than tenfold. Therefore, it will have expansive applications in the petro-chemical industry.
