Apparatus for loosening or removing the skin from products such as nut kernels, beans, seeds or the like. Carriers are arranged to receive the products and a liquid jet manifold is adapted to direct jet or jets at the products. In a preferred embodiment, the products are disposed in an annular recess in a carrier, and are subjected to jets of liquid discharged from two nozzles at each end of a bar arranged to rotate above the recess.

A process and apparatus is disclosed for loosening or removing the skin from products such as nut kernels, beans, seeds or the like. The process comprises subjecting the products to a jet or jets of water at ambient temperature so as to loosen or remove their skins. The apparatus includes carriers arranged to receive the products and a liquid jet manifold adapted to direct the jet or jets at the products. In a preferred embodiment, the products are disposed in an annular recess in a carrier, and are subjected to jets of liquid discharged from two nozzles at each end of a bar arranged to rotate above the recess.

A process and apparatus for removing the skin from products such as nut kernels, beans, seeds or the like. The process comprises subjecting the products to a jet or jets of water at ambient temperature in a confined area to cause their abrasion against each other so as to remove their skins. The apparatus includes cages (4) arranged to receive the products and a liquid jet manifold (8) adapted to direct the jet or jets at the product.

The present invention provides a novel process for removing the pellicle from nut kernels and a blanching composition for use in the treatment of nuts. More particularly, the process of the invention comprises the steps of: (a) immersing nut kernels in a composition comprising a mixture of a vegetable oil and a wetting agent in a solution of water and, optionally, a sugar, at ambient temperature to soften and loosen the pellicle; (b) removing the nut kernels from the composition and draining the nut kernels; (c) exposing the nut kernels to ambient temperature water to remove the pellicle; and (d) separating the nut kernels from the pellicle.

A method for drying nuts that includes removing, acids, particularly tannins, and stopping enzymatic activity within the nut prior to drying provides a novel approach to processing nuts that has many useful characteristics. In one embodiment, walnuts are first blanched in water for 3 to 5 minutes to remove acids and stop enzymatic activity without causing the nut oils to react and are then reduced to a partially dehydrate state of 2% water. Nuts so prepared are dried without inducing rancidity producing reactions that normally occur when drying tannin-containing nuts and have less of a bitter taste associated with the tannins. Additionally, the nuts may be glazed to form a protective coating that inhibits oxidative reactions between the atmosphere and the nut, and which provides a convenient and tasty snack food.
