Abstract

Die Erfindung betrifft ein Verfahren sowie eine Vorrichtung zum Trennen eines Bruchgutes, bestehend aus gebrochenen Körnern oder Bohnen und ihren Schalen, insbesondere zur Trennung von Kakaobruch (Nibs) von Kakaobohnenschalen, wobei die Trennung elektrostatisch erfolgt, indem das Bruchgut in franktionierter Form in einer Aufladungszone zwischen zwei unterschiedlich geladenen Elektroden elektrisch aufgeladen, anschließend im freien Fall in einem von zwei anderen, die Freifallstrecke begrenzenden Elektroden erzeugten homogenen elektrischen Feld entladen und danach mittels eines mechanischen Separators in zwei getrennten Produktströmen, bestehend im wesentlichen aus einem Kernbruchstrom und einem Schalenstrom, weggefördert wird. Durch unterschiedlich starke Ablenkung der Bruchgutteilchen in der Ablenkzone wird der Kernbruch von den Schalen getrennt, wodurch mit einem relativ geringen apparatetechnischen Aufwand Trennergebnisse erzielbar sind, die bisher nur mit Hilfe von Sieb- und Windsichtvorrichtungen und damit kostspieligeren Apparaten erreicht wurden.
