Abstract
A branch for distributing granular material includes an inlet portion, a transition portion downstream of the inlet portion, and an outlet portion downstream of the transition portion. Each portion has a critical air flow rate that is required to cause the granular material to flow through the respective portion. The branching that occurs at the transition portion results in the critical air flow rate of the transition portion being greater than the critical air flow rate of the inlet portion, typically requiring an amount of air at least equal to the critical air flow rate of the transition portion to flow granular material through the branch. In the disclosed branch, the inlet portion is oriented relative to the outlet portion such that applying air to substantially equal the critical air flow rate of the inlet portion results in granular material being urged by gravity to move through the transition portion and into the outlet portion.
