An intake conduit apparatus comprises an intake conduit adapted at a downstream output end thereof for connection to an intake of a vacuum conveyor, and adapted at an upstream input end thereof to facilitate entry of granular material. Ramps slope inward and downstream from the interior wall of the intake conduit, and there is a vent hole through the wall of the intake conduit adjacent to a downstream end of each ramp such that air enters the intake conduit adjacent to the downstream end of each ramp.
