FIELD: ultrasonic cleaning of products.
SUBSTANCE: essence of the invention is that the products are immersed in a washing liquid, ultrasonic vibrations created by a piezoelectric transducer are excited in it, and nominal and pulsed conversion modes are combined when ultrasonic vibrations are excited by piezoelectric transducers. When a pulsed ultrasonic signal is generated due to negative feedback, the power unit ensures the accumulation of energy from a constant power source during the absence of a discrete radiation signal, which allows one to accumulate energy and produce peak signals at which the power of the generated discrete shock-resonant pulsed ultrasonic signal is 5-10 times higher than the nominal power of the continuous signal.
EFFECT: ensuring the possibility of high quality cleaning of products.
