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).
Selon l'invention, on tamise des particules (P) contenues dans un liquide (3) en les plaçant sur une surface de tamisage (3) située dans une monture de tamis (2). Le tamisage s'effectue par exposition du fluide (F) à des vibrations ultrasonores (U). Ces dernières sont produites au moyen d'un ensemble ultrasonore (4) qui présente une surface d'incidence de rayonnement (5) pouvant être mise en contact avec le liquide (F), surface sur laquelle au moins un transducteur d'ultrasons (6) est placé sur le côté (7) opposé au liquide. L'ensemble ultrasonore (4) présente une surface d'incidence (5) pratiquement conique..
