A multi-chamber funneling hopper having at least first and second frustum-shaped containers, with the second container being disposed above the first container. The first container includes a first inwardly-sloping wall and three non-inwardly-sloping walls, the walls defining a first chamber having a first inlet and a first outlet positioned below the first inlet and of smaller area than the first inlet. The second container has a second inwardly-sloping wall and three non-inwardly-sloping walls, the walls defining a second chamber having a second inlet and a second outlet of smaller area than the second inlet and as large as the first inlet of the first container. The first container and the second container define a vertical axis passing therethrough, and the first and second containers are positioned relative to each other so that the second inwardly-sloping wall is rotated in a horizontal direction approximately ninety degrees relative to the first inwardly-sloping wall.
