An automatic de-shelling machine includes a hopper, an orienting section, a shelling section and a push blade. The hopper receives the nuts and directs the nuts to the orienting section, from where the nuts passed to the shelling section. The orienting section includes a first jaw assembly, at least one first resilient element and the shelling section includes a second jaw assembly and at least one second resilient element. The first and second resilient elements are disposed between and connect the jaws of the first and second jaw assembly respectively. The first and second jaw assembly are having jaws disposed opposite to each other and moving relative to each other to cause uniform, symmetrical expansion and contraction of space defined between the jaws, such that a center plane of the nut held between the jaws is always maintained in co-planar relation with respect to plane of symmetry of the jaws.
