Abstract: A portable machine incorporating a first chamber in which pecans are subjected to drum mounted resilient flails which cooperate with a roughened chamber portion in effecting a separation of the husks or hulls of the pecans. A second chamber located outward of the first chamber receives the pecans, hulls and other vegetation which might have been gathered with the pecans with all of the materials in the second chamber being subjected to a separating flow of air whereby the normally heavier pecans are allowed to pass therethrough with the lighter hulls and other materials being air separated from the pecans.
