A nut meat extractor includes a hollow segment, journalled about a drive shaft, having minor upper and major lower bases, each base defining a unitary surface. The segment includes a conical lateral surface between bases, the surface including splines having interdigitating spaces. A hollow cylinder is proportioned for symmetrical containment of the conical segment, an interior of the cylinder opposing the lateral surface of the conical segment and defining a pattern of elevated protrusions for interaction with shells of nuts introduced into the extractor between the conical segment and the interior of the cylinder. The interaction and pressure on shells of the nuts increases downwardly with the advance of nuts fed into an upper region between the upper base and the interior of the hollow cylinder. Pressure upon shells of the nuts increases with advance to the lower base until the nuts are cracked.
