Winnowing is a process by which chaff is separated from grain. It can also be used to remove pests from stored grain.
Prior to mechanization, grain that had gone through the process of threshing, was winnowed by tossing the beaten grain into the air so the chaff could be carried away by the wind, and the heavier grain fell back down onto the theshing floor.
This machine, made of wood, nails, metal gears and screens, creates a breeze that blows away the chaff of the grain. Grain is fed into the machine from the top. A hand crank drives a large gear, turning large wooden fan-like paddles. The screens filter the grain at the bottom of the machine. This grain is now ready to be ground, or stored for future use.
