Abstract

Die Erfindung bezieht sich auf ein Verfahren und eine Vor­ richtung zur Saatgutaufbereitung. Der neue Verfahrensschritt besteht darin, daß der Gutstrom zwecks Vorsortierung einem quer zur Gutstromrichtung gerichteten Gutstrom ausgesetzt und im Leichtgut, Mischgut und Schwergut aufgeteilt und nur das Mischgut der weiteren Sortierung unterworfen wird. Die Vorrichtung zur Vorsortierung besteht aus einem Ringkanal (1), der aus zwei gegenüberliegenden gekrümmten Abschni­ tten (2, 2′) und zwei gegenüberliegenden geraden Abschni­ tten (3,3′) zusammengesetzt ist und in dem ein Querstrom­ gebläse oder Axialventilator (4) angeordnet ist. Der Ringkanal (1) weist im Wandbereich seiner inneren Um­ fangsbegrenzung (5) am Anfang einer der gekrümmten Abschnitte (2, 2′) einen über die Breite des Ringkanals (1) sich erstreckenden Einlaßschlitz (6) für das Saatgut und im Wandbereich seiner äußeren Umfangsbegrenzung (7) gegenüber dem Einlaßschlitz (6) eine über die Breite des Ring­ kanals sich erstreckende Auslaßöffnung (8) für das Saatgut auf. Durch die Erfindung können die erforderlichen üblichen Sortiereinrichtungen kleiner dimensioniert werden bzw. bei bestehenden Anlagen deren Leistung gesteigert werden. The invention relates to a method and a front direction for seed processing. The new process step is that the material flow for the purpose of pre-sorting exposed to the flow of material directed transverse to the direction of the flow of material and divided into light goods, mixed goods and heavy goods and only the mix is subjected to further sorting. The Pre-sorting device consists of a ring channel (1), which consists of two opposing curved sections tten (2, 2 ′) and two opposite straight sections tten (3.3 ') is composed and in which a cross flow blower or axial fan (4) is arranged. The ring channel (1) points in the wall area of its inner order catch limitation (5) at the beginning of one of the curved Sections (2, 2 ') one across the width of the ring channel (1) extending inlet slot (6) for the seed and in Wall area of its outer circumference (7) opposite the inlet slot (6) across the width of the ring channel extending outlet opening (8) for the seed on. Through the invention, the required usual Sorting devices are dimensioned smaller or at existing systems whose performance will be increased.
