Abstract

An oyster shell separator deploys a conical, helically ridged, powered point driven in rotation by an electrical motor within a wedge shaped housing. The conical point draws the shells onto a flanged collar selected in dimension to fully separate the shells. From the collar the shell halves are passed along the sides of the housing for collection and sorting.
