Abstract
A pistachio huller is provided wherein a means having projections pushes unhulled nuts between the surface of the means having projections and a surface of a means having slots, the slots being narrower than the pistachio nuts to be hulled. The projections protrude into the slots and the hulls are ruptured and abraded through contact between the surface of the means with projection and the surface of the strips forming the means having slots whereby the nuts are hulled.
Claims3
A method of removing hulls from pistachio nuts said method comprising the steps of
- (a) depositing unhulled pistachio nuts between rotating means having projections extending outward from a surface thereof and a means having slots, said projections being spaced apart on said surface and said surface movably mounted on support means with said surface having projections disposed in close proximity to [the] a surface of said means having slots so that the projections extend into the slots, said slots being narrower than the pistachio nuts;
- (b) passing said unhulled pistachio nuts between the surface having projections and [a] the surface of said means having slots by means of moving the surface of said means having projections, so as to push said pistachio nuts in said slots with said projections;
- and
- (c) abrading said hulls from said pistachio nuts by means of the surface having projections and the surface of said means having slots contacting said hulls while said unhulled pistachio nuts pass between said surface having projections and said surface of said means having slots.
A method of removing hulls from pistachio nuts said method comprising the steps of:
- (a) depositing unhulled pistachio nuts between rotating drum having projections extending outward from the peripheral surface of said drum and a means having slots, said projections being spaced apart on said surface and said surface movably mounted on support means with said surface having projections disposed in close proximity to [the] a surface of said means having slots so that the projections extend into the slots, said slots being narrower than said pistachio nuts;
- (b) passing said unhulled pistachio nuts between said peripheral surface and [a] the surface of said means having slots by means of rotating said drum, so as to push said pistachio nuts in said slots with said projections;
- and
- (c) abrading said hulls from said pistachio nuts by means of the surface having projections and the surface of said means having slots contacting said hulls while said unhulled pistachio nuts pass between said surface having projections and said surface of said means having slots.
A method of removing hulls from pistachio nuts said method comprising the steps of:
- (a) depositing unhulled pistachio nuts between a movable belt having projections extending outward from a surface thereof and a means having slots, said projections being spaced apart on said surface and said surface movably mounted on support means with said surface having projections disposed in close proximity to [the] a surface of said means having slots so that the projections extend into the slots, said slots being narrower than said pistachio nuts;
- (b) passing said unhulled pistachio nuts between said surface having projections extending therefrom and [a] the surface of said means having slots by means of moving said surface having projections so as to push said unhulled pistachio nuts in said slots with said projections;
- and
- abrading said hulls from said pistachio nuts by means of the surface having projections and the surface of said means having slots contacting said hulls while said unhulled pistachio nuts pass between said surface having projections and said surface of said means having slots.
