Winnower

thingiverse

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.
