With a pre-classifier system you can make the whole process much more efficient. You can make your own, but you might want to take a look at this set of sieves made for gold panning that fit on top of a 5-gallon bucket. The smallest sizes are way too small for winnowing (but may have other uses around the workshop) but the larger ones are perfect for pre-classifying. Individual sieves are also available - consider the 2 (1/2" - good for catching flats and uncracked beans), 4, 8, and 12 mesh.
