Here we see some of the details of the Rotating Sifter at George Washington's Gristmill. The drive belt between the wheels would have been leather back in Geo. Washington's day, but today they are made of heavy duty canvas for ease of use. Flour comes down the diagonal chute from the cooler/dryer on the Fourth Level where it is put inside the silk wrapped drum inside the wooden box.
The first part is a finer silk that allows only the finest flour through it, the remaining flour goes through a coarser silk wrapped drum. The flour falls through chutes under the sifter to waiting barrels on the Second Level.
