Abstract:
1. A method of separating a particulate residue stream, comprising: directing a first particulate residue comprising chaff into a first particulate residue intake of a first, intake end of an air plenum of a harvesting device; directing a second particulate residue comprising straw into a second particulate residue intake of the first, intake end of the air plenum, downstream from the first particulate residue intake; directing outside air through an outside air intake, upstream from the first particulate residue intake, to form a first particulate residue air stream comprising the first particulate residue and a second particulate residue air stream comprising the second particulate residue within the air plenum moving in the direction of a second, exhaust end of the air plenum; and directing the first particulate residue air stream and the second particulate residue air stream past an angulated baffle comprising a first major portion and a second minor portion near the second, exhaust end, and within the plenum so as to maintain the first particulate residue of the first particulate residue air stream and the second particulate residue of the second particulate residue air stream substantially separated upon discharge from the plenum for the separate collection thereof, and not directed to a spreader or chopper for spreading on the ground, but rather to facilitate the separate collection of the first particulate residue and the second particulate residue for further processing of at least one of the first particulate residue and the second particulate residue.
