Based on the analysis of disadvantages of the green-husk walnuts stripping methods and the characteristics of ripened walnuts, the pressing test was carried out, and pressure-deformation figure of ripened green husk walnut was mapped. By analysis of test data, the breakdown pressure and the corresponding compression of the ripened walnut green husk and shell were determined. Based on the significant difference on breakdown pressure between the green husk and shell, and the state of green husk rupture and separation by pressing, the method of stripping off green-husk by pressing is put forward. These results provide the basis for new equipment development.
