摘要： A vertically elongated chamber has a current of air blowing upwardly therethrough so that leaves deposited into the chamber are subjected to a combined effect of gravity and airflow and heavy stems of the leaves are thus oriented downwardly; conveyor means in the chamber translate the leaves laterally so that the leaves move, stem first, through an outlet passage at one side of the lower portion of the chamber. The leaves then fall onto a discharge conveyor with their stems oriented in the same direction. A zone of reduced pressure at the upper end of the chamber prevents the leaves being blown out the top of the chamber. Kicker means within the chamber above the conveyor means aid in separating leaves which may be stuck together.
