  • Patent number: 4132162
    Abstract: An apparatus for removal of the epidermis from fruits and vegetables by an abrasive process. The apparatus includes a drum having rotating abrasive coated rolls positioned about the periphery. Rotation of the drum and rollers causes the product passing through to contact the abrasive-surfaced rolls for removal of the peel. To preserve the removed peel material and to conserve water, the peeling process is done in a dry environment during the initial stages with water only being introduced at the exit end of the apparatus to wash from the product any remaining peel particles.
