|Have you ever seen plans for a lima bean sheller? I saw a sheller years ago that was a wire cylinder about 3-4' long and 24" in diameter. Going through the center of the cylinder was a beater bar. The cylinder was turned slowly by an electric motor. After the beans dropped down on the beater bar several times, the shell would open and the beans would fall out. The beans would drop through the openings in the wire cylinder but the shells were too large to pass through. It could shell a bushel of beans in 10-15 minutes.|
|Lehmans "Non-Electric" catalog (http://www.lehmans.com/) sells a product called a Texas Pea Sheller:
from catalog listing: "Finally, an efficient way to shell peas and beans - much
faster than hand shelling! Peas or beans are squeezed from
their hulls. Can be motorized (handle shaft attaches to
portable mixers). Brass gears, aluminized steel body, no-slip
serrated plastic rollers. 4 in. H x 4 in. W, clamps to surfaces
from 3/4 in. to 1 3/4 in. thick. 2 lb, USA made."
Hope this helps!
