NUT SHELL SEPARATING APPARATUS Russian patent published in 1998 - IPC

FIELD: equipment for cracking and separating shell of nuts, particularly, walnuts. SUBSTANCE: apparatus has two disks with special profile of working surfaces. Space between disks corresponds to sizes of fruits of nuts to be cracked and shelled. Fruit is positioned between disks. In the process of cracking, fruit changes its position in space and is subjected to compression alternatively in different directions. It allows improved grinding of nut shell without damaging fruit core to be provided. Core is separated from cracked shell by means of axial fan with impeller fixed on rotating working disk. Small fraction of core is separated from shell on netted portion of bottom of shell discharge casing. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 2 cl, 1 dwg
