Abstract: Raw material devices, systems that incorporate raw material delivery devices, and methods of supplying raw material using the raw material devices. A raw material delivery device includes a hollow body comprising a first end and a second end, the second end disposed above the first end in a system vertical direction, an inlet disposed at the first end of the hollow body, an outlet disposed at the second end of the hollow body, and a stepped passageway disposed within the hollow body between the inlet and the outlet. The stepped passageway is configured to deliver raw material via one or more steps from the inlet to the outlet.
