Gerät nach dem vorhergehenden Anspruch, dadurch gekennzeichnet, dass die Verbindungselemente zwischen der Vorrichtung zum Trennen und dem starren Rahmen mindestens ein Klemmorgan, insbesondere eine Druckfeder, aufweisen, das konfiguriert ist, um die Vorrichtung zum Trennen (10) gegen die Kontaktfläche des starren Rahmens zu klemmen, indem die Dichtung (24) in einer Weise komprimiert wird, die die Übertragung der Ultraschallvibrationen auf den starren Rahmen begrenzt oder sogar verhindert.
  13. Gerät nach einem der Ansprüche 10 bis 12, dadurch gekennzeichnet, dass die Zuführvorrichtung ein Schütten der Produkte auf der gesamten Breite des Filter- oder Siebelements insbesondere in Form von einem Produktvorhang von konstanter Dicke gewährleistet.
  14. Gerät nach einem der Ansprüche 10 bis 13, dadurch gekennzeichnet, dass es ein Element aufweist, um die Rückstände zu enthalten, die aus dem Filter- oder Siebelement abgeführt werden.
  15. Gerät nach einem der Ansprüche 10 bis 14, dadurch gekennzeichnet, dass es mehrere Vorrichtungen zum Trennen (10) aufweist, die derart konfiguriert und übereinander gelagert sind, dass sie von oben nach unten gehend abnehmende Durchmesser zum Zurückhalten aufweisen, wobei die zu trennenden Produkte, die einer anderen gegebenen Vorrichtung zum Trennen zugeführt werden, als jener, die am obersten angeordnet ist, durch die Durchgänge von der Vorrichtung zum Trennen direkt darüber gebildet sind.
  16. Verfahren zum Trennen von Produkten, das ein Gerät nach einem der Ansprüche 10 bis 15 verwendet, umfassend einen Schritt des Trennens der Produkte in Durchgänge durch das Filter- oder Siebelement und Rückstände, dadurch gekennzeichnet, dass sich das Trennen ausschließlich aus Ultraschallvibrationen des Filterelements ergibt, die durch das in Vibration Versetzen der Struktur durch den elektroakustischen Wandler induziert werden.
  17. Verfahren zum Trennen von Produkten nach Anspruch 16, umfassend mindestens eine Vorrichtung zum Trennen nach einem der Ansprüche 3 bis 9, dadurch gekennzeichnet, dass der Schritt des Trennens der Produkte durch Fließen (16) der zu trennenden Produkte entlang dem Filter- oder Siebelement der Filtervorrichtung mit einem Verteilen der Produkte, die die Durchgänge bilden, die das Filter- oder Siebelement durchqueren, in Abhängigkeit von einem Korngrößengradienten, der in Fließrichtung zunimmt, erfolgt.
  18. Verfahren zum Trennen nach Anspruch 17, dadurch gekennzeichnet, dass es ein Anpassen der Fließlänge der zu trennenden Produkte in Abhängigkeit von einem gewünschten oberen Schwellenwert der Korngröße der Durchgänge aufweist.
