Info: Flour Sifter
Komo grain mills are great for wresting every last bit of the grain into a nutritious whole grain flour, but for some types of baking such as making delicate pastries, the best results are achieved using pure white flour. This cylindrical flour sifter fits on almost any electric Komo grain mill (all except the Jumbo model), which will let the finer-grained white flour pass through the screen on its bottom as it spins, while holding back the bran (which you can then use in muffins or other recipes). It comes with three interchangeable sieve inserts, in medium, fine and extra fine mesh sizes.
The unit comes with three interchangeable sifting screens, of Fine, Medium and Coarse grain (whose openings are 0.63, 0.8, and 1.25 mm in diagonal), which you select depending on the type of flour you are sifting and which components you want removed.
The entire device, which consists of a Plexiglas cylinder with a Beechwood top and bottom (and a metal screen and two small brushes and other parts in the bottom), is about 11 inches high, altogether, including its base. It has a 3 year limited warranty.
Any type of grain flour can be used in this sieve, not just wheat -- anything from spelt to rice to maize. Simply attach one of the mesh screens to the bottom;* fit the device onto your grain mill; fill the cylinder with the flour to be sifted (it can hold up to about 450 grams at a time); turn on your mill; and watch as the finely sieved flour drops out of the outlet at the bottom (as it is swept over the mesh screen by two small brushes rotating at the bottom of the cylinder), leaving the bran or more fibrous material behind, remaining in the cylinder.
* The dimensions of the openings in the mesh screens are given and shown in close-up in the second product image, and the second of these two videos shows how to insert or change them. (These videos are for illustrative purposes; please note, they are in German.)
