Windhexe
A windhexe is a machine that combines the properties of a blender and a blow dryer. Pressurized air is forced into a conical chamber where it forms a high speed vortex which tumbles material against the inside wall, pulverizing it into a fine powder. Windhexe was invented by Frank Polifka.
The machine is a variation on the Hilsch vortex tube.
The name is German, literally meaning "wind witch".
