The Robur augur is a bit of a kluge. Horizontal bulk grinders, which have flat burrs without a bean grabbing area, use a helical screw inside a tube to force the beans into the grindstones. So if you want a truly effective single dose, non-popcorning setup, the same thing set vertically, i.e. a tube enclosing a helical screw, would work best.
Home meat mincing/sausage making machines use ABS plastic helical screws; so somebody who believes popcorning is evil, but still wants to try single dosing, can try this out.
