A nut dehulling apparatus for more effectively removing the green hull or shuck from pecans includes a housing having a housing inlet and a housing outlet. A rotatable scrubbing means and an endless conveyor belt are disposed in the housing. Further included is a means for rotating the scrubbing means and means for moving the endless conveyor belt. The endless conveyor belt includes a nut contact portion which, along with the rotatable scrubbing means, defines a nut passageway wherein the scrubbing means engage pecans. The nut passageway circumscribes approximately one-half the scrubbing means. The endless conveyor belt is located in the housing such that nuts deposited in the inlet are carried by the conveyor belt through the nut passageway into engagement with the scrubbing means. The separated nuts and hulls are then carried by the endless conveyor belt to the housing outlet. The apparatus also includes a vacuum source disposed in the housing. The vacuum source communicates with the lower surface of the nut contact portion of the endless conveyor belt and acts to pull that portion of the endless conveyor belt away from the scrubbing means. The vacuum source thus provides a means for reducing wear and tear on the endless conveyor belt and the scrubbing means.
