The invention discloses a method for stripping off green husks of nuts through a mechanized dry process and relates to a fruit processing technique, in particular to a processing technique for stripping off the green husks of the nuts. Crossed reticular knife marks are cut on the surfaces of fermented mature green nuts through two spiral knife rolls which have opposite spiral directions and rotate in the same direction at different speeds, and then the spiral knife rolls rotate to apply tangential force and axial force on the nuts to rotate and turn over the nuts so as to enable the green husks to be split and separated from the surfaces of the nuts. Since the spiral knife rolls have sharp edges, when the spiral knife rolls cut into the green husks, sap in the green husks is not squeezed out and is prevented from contaminating the exterior surfaces of the nuts during processing. Though the entire green husk stripping motions are equivalent to simulated manual stripping actions, the mechanized high-efficiency application of the green husk stripping action is realized. Therefore, the invention provides the effective method for stripping the green husks of the nuts through the dry process.
