Patent ID: 8088227

Claim:
Method for the sonic treatment and cleaning of objects in a tank ( 5 ) that is equipped with liquid ( 6 ) and at least one sound source field ( 8 ), wherein the objects ( 2 ) are continuously transported on a transportation device ( 3 ) through the tank ( 5 ) and over the at least one sound source field ( 8 ), wherein the at least one sound source field ( 8 ) comprises several oscillation sources tuned to emit sound ( 8 b ) in-phase into the liquid ( 6 ) to impinge on objects with its oscillation maximum, further wherein the at least one sound source field ( 8 ) is arranged: I. inclined less than Lambda/2 with respect to the plane of the object to be cleaned ( 2 ), wherein Lambda designates the wavelength of the sound ( 8 b ) emitted; or II. movable and parallel to the plane of the object to be cleaned ( 2 ), wherein the movement is carried out either vertically or vertically and parallel to the plane of the object to be cleaned ( 2 ); thereby ensuring that the sound ( 8 b ) impinges on the surface of the object ( 2 ) with at least one oscillation maximum.
