This shows grain amaranth being winnowed using a squirrel-cage fan that has been modified to include a rotary dimmer switch. This allows tight control over air speeds. The amaranth is dropping from a sloped tray into the airstream and falling into three trays that collect various densities of grain. The fan is set to speed #1 and it is "dimmed" to about half that speed. For more information try: http://www.geopathfinder.com/Winnowin...
