A seed shucking appliance for separating seed coverings from their kernels comprises a vertical cylinder within which is rotated an upward pointing and rotating cone. The top surfaces of the cone and the inside surfaces of the cylinder are roughened to catch and grate the skins or hulls off water-softened beans or grains poured in from above. The clearances and textures between the roughened cone and inside cylinder are such that most of the skins or shells stay above the cone after being knocked loose, and the bared seed kernels drop down through without necessarily being ground up or smashed. What drops through is sent to a water bath where any remaining skins or shells are floated away. The bared seed kernels are drained and ready to be used as whole seed kernels in various kinds of foods.
