Abstract
A chip chute for transporting wood chips includes: first, second, third, and fourth planar lateral walls defining an open area having a rectangular cross-section, with an inlet opening configured to receive the wood chips, wherein the first and second planar lateral walls oppose each other and extend in a height (H) direction and a first length (Li) direction, and wherein the third and fourth planar lateral walls oppose each other and extend in the height (H) direction and a second length (L2) direction perpendicular to the first length (L1) direction; a curved bottom wall that is located at a bottom of the planar lateral walls and curves from the first planar lateral wall to the second planar lateral wall; and a cylindrical outlet tube protruding laterally from one of the planar lateral walls and configured to discharge the wood chips.
