Flour Millers Toolkit for Implementing Wheat and Maize Flour Fortification

The Flour Millers Toolkit offers basic information for wheat and maize flour fortification. The Toolkit is a set of Power Point slides that include speaker notes for more information.

Among the technical topics covered are:

  • The most common way to fortify flour is using a micro feeder. This adds premix to flour at pre-determined rates in the process of flour production.
  • Three types of feeders are available: screw, revolving disk and drum or roller. Screw feeders are the most common. They dispense a set volume of premix at a constant rate. The size of the screw determines the feed rate capacity, and this allows a wide range of delivery rates.
  • Mills generally need one feeder per type of flour or meal line to be fortified. The size and number of feeders needed depends on the amount of flour produced per hour.
  • Magnets are used in flour production to remove unwanted substances like staples or other metal pieces. Most iron compounds used in fortification (ferrous sulfate, ferrous fumarate, and sodium iron EDTA) are not attracted to magnets. Elemental iron, which is sometimes used for fortification, may be attracted to the magnets, but only rare magnets are strong enough to pull this iron from flour.

The most current version of the Toolkit is only available in English. Older versions are available in Arabic, Chinese, Française, and Russian.
