Abstract: An apparatus for removing hulls from nuts includes a rotating drum with protrusions on its surface, a hulling plate and a separator plate. Rotation of the drum causes nuts deposited on an upper surface of the drum surface between the hulling plate and the separator plate to be impinged by the protrusions against the hulling plate, thereby removing the hulls and pushing the hulls through a hulling gap between the hulling plate and the upper surface of the drum, while the hulled nuts pass through a separator gap between the separator plate and the upper surface of the drum, thereby separating the hulled nuts.

Abstract: An apparatus and method for separating nuts of different buoyancy in a liquid. The apparatus has a tank, a support frame, and a particle collecting device. The particle collecting device has a shell that is attached to and wraps circumferentially around an auger shaft that is rotatably mounted to the support frame. As the auger shaft is rotated about its axis, the attached shell is rotated in the liquid in the tank and its spiral shape directs nuts onto the auger shaft, and the auger surface advances the nuts towards an end opening of the shell disposed outside of the tank.

Abstract: An apparatus for separating blank pistachio shells and other debris from pistachio nuts includes a flotation tank, a weir and discharge channel, a conveyor within the flotation tank and a pair of counter-rotating rollers for squeezing floating items and for urging floating items towards the weir and discharge channel.

Abstract: An apparatus for drying and conveying pistachios comprises a plurality of fixed and moveable slotted plates. The moveable plates are interleaved with the fixed plates and reciprocate to push pistachio nuts along the surface of the plates. Heated air is blown through the plates to dry the pistachios.

Abstract: An apparatus for separating hulled and unhulled pistachios includes a rotating roller and a conveyor for depositing pistachios onto the roller. Rotation of the drum frictionally separates hulled and unhulled pistachios.
