Fengshanche
Winnowing machine used in ancient China
Fengshanche was a winnowing machine that was used in ancient China to separate the grain from the chaff or seed casings after harvest. The winnowing machine also had a rotary fan which had a blower that had a crank handle to create air to blow away the lighter seed casings to separate the husks from the pile of grain.
