Abstract
Particles (P) contained in a liquid are sieved by placing them onto a sieving surface (3) located inside a sieving frame (2). The sieving process ensues by subjecting the liquid (F) to ultrasonic oscillations (U). The ultrasonic oscillations (U) are generated using an ultrasonic device (4) having an ultrasonic irradiation surface (5) that can be brought into contact with the liquid (F). At least one ultrasonic transducer (6) is arranged on the side (7) of said ultrasonic irradiation surface that faces away from the liquid. The ultrasonic device (4) comprises an approximately conical ultrasonic irradiation surface (5).
