Problems solved by technology

[0005] In the above two types of methods, except for the low-efficiency manual peeling method, the remaining mechanized peeling methods inevitably squeeze out a large amount of juice in the green skin during processing, so it is necessary to use water to clean the surface of the nut, ot...

Embodiment Construction

[0012] Below, the present invention will be further described in conjunction with the accompanying drawings.

[0013] The present invention is a method for mechanized dry peeling of walnut green skin, which uses two right-handed spiral knife rollers 1 and left-handed spiral knife rollers 2 with opposite helical directions but the same direction of rotation and different speeds on fermented and mature green walnuts. 3. Cross-shaped left-handed spiral cut marks 5 and right-handed spiral cut marks 6 are cut out on the surface; the tangential force applied to the walnut fruit by the edge of the spiral knife roller makes the walnut fruit rotate vertically along the direction shown in 7, because figure 1 The rotating speed of middle right-handed spiral knife roller 1 is faster than the rotating speed of left-handed spiral knife roller 2 (also can be vice versa), so the axial force 9 applied by right-handed spiral knife roller to green walnut fruit 3 is higher than the axial force app...

Abstract

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.

Description

Technical field [0001] The invention relates to a fruit processing technology, in particular to a processing technology for peeling walnut green skin. Background technique [0002] After the walnut fruit is ripe and picked, the green skin on the surface must be peeled off at an appropriate time to ensure that the surface of the nut is clean and beautiful, and the nuts are white and fresh; currently, the processing methods for peeling off the green skin on the surface are mostly the following two types: [0003] (1) After the green skin is fermented (the core and the outer green skin are basically separated), the surface green skin is manually removed or mechanically rubbed and scraped to remove the green skin. Typical technical solutions refer to the green walnut peeling machine disclosed in ZL200820130420.1 and the scraping type walnut green peeling machine disclosed in ZL200720104461.9. [0004] (2) After the green skin is properly fermented and softened, use a knife stri...
