After first grinding flour from grain, just unscrew the mill's hopper, lift out the upper stone, and screw the sifter assembly on where the hopper was. With your just-milled flour in the sifter chamber, flip the mill switch on, and rotating brushes quickly work the finest flour through the screen at bottom, and out through the mill spout, so the bran remains above.
A strong tornado-like vortex is formed in the flour during operation, which quickly circulates all the flour through the chamber.
The KoMo flour sifter includes 3 interchangeable screens in coarse, medium and fine. The mesh sizes are 1.25mm (15 mesh), .80mm (19 mesh) and .63mm (24 mesh). Capacity is 14 ounces.
Grain mill not included.
