Abstract
A peanut cleaner for cleaning freshly harvested peanuts in the field includes structure for initially vibrating the peanuts to loosen moist field soil, trash, fines and clinging vine segments therefrom, structure for thereafter subjecting the loosened soil, field trash, fines, vine segments and peanuts to a free fall downwardly along a substantially vertical flow path while subjecting the vertical flow path to a lateral and slightly upwardly inclined flow of at least slightly dehumidified air to thereby blow at least the lighter loosened soil, field trash, fines and vine segments laterally from the vertical flow path of peanuts and still further structure for repeatedly elevating the peanuts from a reticulated support surface therefor and allowing the peanuts to free fall, by gravity, back downwardly onto the reticulated surface to thereby loosen and remove therefrom any remaining clinging soil, field trash, fines and vine segments from the peanuts.
