Method for separating the shell from seeds or fruit, sifting device, and selection device

A method for separating husks from organic products, wherein the organic products include at least one of fruits or seeds, and wherein the method comprises:

• feeding the organic products into a splitting machine that hits the husks, thereby separating the husks from only a portion of the organic products;
• transporting the organic products and the separated husks, after said feeding the organic products into a splitting machine, inside a first rotary screen including perforations configured to pass husk-less organic products and the separated husks and further configured to retain husked organic products;
• rotating the first rotary screen whereby the organic products are moved and the husk-less organic products and the separated husks pass through the perforations, thereby falling into at least one collection portion;
• and
• transporting the husk-less organic products, the separated husks, and the husked organic products to at least one component comprising a downwardly sloped region followed by an upwardly curved region followed by a ramp, wherein at least a portion of the upwardly curved region or the ramp comprises corrugation, wherein:
• the husk-less organic products, the husked organic products, and the husks travel down the downwardly sloped region and up the ramp, thereby becoming airborne;
• the airborne husk-less organic products land in a first classifying portion;
• the airborne husked organic products land in a second classifying portion;
• and
• the airborne separated husks land in a third classifying portion.

A device for screening husked organic products, husk-less organic products, and separated husks, the device comprising:

• a first rotary screen including an inlet, an outlet, and perforations;
• a rotating portion located on a transverse axis of the first rotary screen;
• wherein:
• the perforations comprise a V-shape;
• and
• the perforations are configured to pass the husk-less organic products and the separated husks, but not the husked organic products.

A system for selecting organic products or husks, the system comprising:

• a sloped region;
• a curved region at following the sloped region, wherein the curved region includes:
• a point of inflection where the direction of the curved region begins sloping upwardly;
• and
• a corrugated region;
• a ramp extending from the curved region;
• a classifying section;
• and
• wherein:
• the system is configured such that the organic products with or without husks and the husks themselves travel down the sloped region, through the curved region, across the corrugated region, up the ramp, into the air, and into a particular area of the classifying section depending on whether an item is a husked organic product, a husk-less organic product, or a husk.
