I and probably many others are at a loss for bulk cleaning techniques for cleaning volumes of our beans, grains, squash seeds etc. Can we get a bunch of experts contributing their tips, tricks, and wisdom? Once we have a lot of information in one place, maybe I can make a wiki out of it.
Plant seeds needing efficient threshing/hulling:
Grains in general
Techniques for other edible seeds are welcome.
Earthworks are the skeleton; the plants and animals flesh out the design.
Here’s good advice for practice: go into partnership with nature; she does more than half the work and asks none of the fee. – Martin H. Fischer
For beans I like to put the dry beans in the hull inside a chicken food bag and stomp on them. Most pop open and release the beans. I aim for 90% or better of the beans leaving the pods. I don't worry about the final 10% because that selectively breeds my bean population into something that threshes easier (I think)
