Particulate residue separators for harvesting devices

A particulate residue separator for a harvesting device, comprising:

• a plenum borne by a harvesting device, the plenum comprising:
• a first, intake end comprising:
• a first particulate residue intake positioned to receive a first particulate residue;
• a separate, second particulate residue intake downstream from the first particulate residue intake positioned to receive a second particulate residue, wherein the first particulate residue comprises chaff and the second particulate residue comprises straw;
• and
• an outside air intake upstream from the first particulate residue intake;
• and
• a second, exhaust end;
• a fan assembly positioned and configured to direct outside air through the outside air intake and form a first particulate residue air stream comprising the first particulate residue, and a second particulate residue air stream comprising the second particulate residue, and direct the first particulate residue air stream and the second particulate residue air stream along the plenum and in a direction of the second, exhaust end of the plenum;
• and
• a baffle located within the plenum downstream from the second particulate residue intake, wherein the baffle is angulated and comprises a first major portion and a second minor portion, the baffle positioned between a pathway of the first particulate residue air stream and a pathway of the second particulate residue air stream and sized, positioned and configured to substantially eliminate mixing of the first particulate residue of the first particulate residue air stream and the second particulate residue of the second particulate residue air stream and maintain the first and second particulate residues substantially separated upon discharge from the plenum for 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.
