Apparatus for stemming tobacco leaves and for segregating the lighter and heavier parts of the resulting mixture comprises a stemming chamber for a rotary stemming unit serving to stem tobacco leaves which are admitted by way of a first inlet of the stemming chamber. The latter has at least one second inlet for admission of a current of separating air, at least one outlet for evacuation of heavier parts, and at least one outlet for evacuation of lighter parts with the air current. The distribution of outlets is such that the direction in which the lighter parts are evacuated with the air current is at least substantially counter to the direction of evacuation of heavier parts. This can be achieved by using the inlet or inlets for air as outlet or outlets for heavier parts.
