Abstract: Disclosed is an apparatus for cracking the husks of nuts comprising a cylindrical rotor having a plurality of cracking projections on its circumference, a semicircular suspension stator having a plurality of cracking projections on its inner surface, the stator being positioned against a corresponding sector of the cylindrical rotor with a downward decreasing gap left between the stator and the rotor, and a hopper with an opening at the bottom for dispensing nuts to the gap between the stator and the rotor. The nutcracker according to the present invention permits simultaneous cracking of nuts of different sizes at an increased efficiency.
