My brother-in-law re-purposed an old hammer drill for a similar purpose, to sift oyster spat sizes. Worked like a charm.

The angle of the table is varied and the rate and magnitude of the vibrations are controlled. Various fabrics are used to adjust the grab on the chaff as opposed to the seed. They seem very effective in the seed industry and I wonder if one could be constructed fairly simply using some device such as a hammer drill of other hand tool with a reciprocating action.
