A picture is worth a 1000 words...and I'm just not up to a thousand words right now. cropped-winnower-sm.JPG

That is the official working model.  40 lb hopper.  Husk bin to contain that and more.  All neat and slip fit with no guess work for assembly.  It breaks down easy for shipping.  It processed 40 lbs of roasted beans into 31 lbs 3 oz of nibs in 31 min 8 seconds. Technical note:  I have a slight riser in the husk waste stream (for overall design reasons, not performance reasons).  It's 18".  I found any more than that and the drag in the tube was too great and the specified vacuum had trouble providing enough suction.

Next it goes into metal, polycarbonate and pvc.  All stainless steel after that.
