Abstract

A pecan nut meat preferably for use with pecans, extractor includes a hollow frusto-conical segment journalled about an axial drive shaft, the segment having a minor upper base and a major lower base, the upper and lower bases each defining unitary surfaces for precluding access to a hollow interior of the segment, the segment including a frusto-conical lateral surface between its upper and lower bases, the lateral surface including a multiplicity of splines having interdigitating spaces similar in polar separation to that of the splines. The extractor also includes a hollow cylinder proportioned for symmetrical containment of the frusto-conical segment below and about it, including elements for securing the cylinder during rotation of the frusto-conical segment, an Interior surface of the cylinder opposing the lateral surface of the conical segment and defining a pattern of protrusions for interaction with shells of nuts provided to the extractor between the surface of the conical segment and the interior surface of the cylinder. The interaction and associated pressure on shells of the nuts increases as a function of axial downward advance of nuts fed into an upper interstitial annular region between the upper base and an upper area of the interior of the hollow cylinder. Pressure upon shells of the nuts increases as a function of advance thereof the lower base until the nuts are cracked, the cylinder bottom including an exit chute permitting release of cracked nuts from the cylinder.
