ABSTRACT:
A drying unit flow separator includes an inlet having a curvature, and an exhaust duct and recirculation duct connected to the inlet at a junction. A recirculation damper is provided adjacent to the junction and projects into the inlet to divide the air flow between the exhaust duct on the outside of the curvature and the recirculation duct. A method of recirculating air to a drying unit includes the steps of blowing air into a curved duct causing larger and heavier lint particles to gravitate to the outside wall of the duct, and conducting the air past a recirculation damper such that the flow is divided into a recirculation flow and an exhaust flow that includes the larger and heavier lint particles.
