Grain flaker

Tool for making rolled oats

A grain flaker is a tool for flattening whole-seed cereal grains. When this is done with oats, the seed form, called groats, becomes a foodstuff called rolled oats. Whole grains store longer but cereals are usually cooked before consumption by humans; the rolling process significantly decreases cooking time. Spelt and wheat can also be rolled. Grains other than oats may need to be softened before they can be rolled. Oat rollers work by flattening the grain against a rolling cylinder. It is possible to build a home-scale manually cranked flaking mill. Oats can also be flaked using a rolling pin or a pasta press.
