    • ]]>     I think that I have a bit more figured out and will post when I have a chance to scan a couple drawings… But I think that what I’ve landed on is a relatively simple air path that draws air via two different paths—one entering through the bean chute, through the drum and out the back toward the chaff collection box; the other entering through the bean tray (cooler) and hooking up with the chaff collection box, where both paths meet and out the door…
    What is nice about this is I can essentially seal off the chamber where the heat source is located and around the exterior of the drum so that I can make this temperature stable and so controllable and responsive.
