shelled corn cleaner

The shelled corn cleaner you are talking about we farmers call a winnower. Basically, you put the shelled corn through screening of different sizes to remove first the big stuff, then the chaff, then smaller amounts of chaff and all. Ours used to have a fan that would blow away the chaff as it went downwards through the screens. Ours had a mechanism that shook the screens while the air was going through it. The screens were placed about 10 inches one above the other (biggest screening on top, and working it's way down to the smallest screening.) I don't know if you're doing the corn for animals, or if you plan on heating with it in a pellet heater, but it's important to keep it dry in either case so it doesn't mold. This is a simple, homemade winnower: After switching your vacuum cleaner nozzle over to the "blow" side, extend the hose by fitting another piece of plastic pipe into its end. Then stick the tube into the bucket full of corn and with the blower on lightly "scoop" the corn up against the side of the container . . . being careful not to push them too high. The corn will fall back into the tub, and the last bits of chaff (hulls, dirt, etc) will be blown away by the hose. Hope this helps some. If not, be sure and write back (hit reply, or send an email through mylot mail above.) I'm sure I have a set of plans somewhere in some of my old farming books from the early 1900's. I don't have a scanner to scan pictures, but I think I could maybe explain it by what I see.
