Problems solved by technology

Ultrasonic transducers are divided into energy-concentrating type that is in direct contact with the processing liquid and divergent type that is not in contact with the processing liquid. The energy-concentrating ultrasonic transducer has local energy concentration, but the uniformity is poor, the probe is in direct contact with the liquid, and cavitation causes damage to it. Fast speed; divergent ultrasonic energy distribution is uniform, the transducer is not in contact with the liquid, and the life is significantly extended, but it is not suitable for the situation that requires local high-energy radiation

Description

technical field [0001] The invention relates to an ultrasonic processing device, which belongs to the fields of food, medicine and chemical industry, in particular to a three-frequency sequential / concurrent non-contact vertical ultrasonic processing device with stirring cycle. Background technique [0002] In the fields of food, pharmaceuticals, and fine chemicals, organic solvents are widely used in traditional chemical reactions, biological reactions, and extraction technologies for effective components of biological resources, because the residual products of solvents have food safety problems; traditional classic reactions or extraction technologies, Due to the long-term method and parameter optimization, the range of improvement in reaction or extraction efficiency is very limited; in traditional thermal processing, high temperature will cause denaturation of heat-sensitive substances and affect the quality of the product. Therefore, the application of physical methods ...
