Abstract
A pneumatic pickup probe or wand, for picking up a dry flowable material from a container and introducing that material into a vacuum conveyor system, constitutes an elongated unitary pickup tube having a plurality of axially displaced air control holes near the vacuum conduit connection end of the tube; the material entry end of the tube is cut off at an acute angle (preferably about 45.degree.), has a narrow, elongated flow modulation slot of about three inches (7.5 cm) axial length extending toward the hose connection end of the tube, and has an anti-closing spacer to preclude blockage of the material entry opening.
