Winnower

Remix of winnower that could be used for winnowing larger fragment sizes, such as cocoa nibs.

The concept is that you attach two bottles on each end and use a fan to blow the husks as the seeds pass the center. See original author's description here: http://www.appropedia.org/2_Liter_Winnower#2-Liter_Winnower

Re-mixed for larger bottle openings (such as found in V8 juice bottles) and a 80mm fan (such as a 12V 80mmx80mmx37mm for large air current that can be adjusted through the use of a voltage regulator). Also added protuberance to be able to attach a bag with a rubber band to collect the husks.

For demonstration purposes only - I do not know what kind of tests would be needed to actually use this for food production. Probably at least the use of a true food-safe filament or it might need to be used to make a mould for casting in a food-safe material.
