Do Different Grains Require Unique Milling Techniques?

Grain Properties and Milling Techniques

The type of grain and its properties play a significant role in determining the optimal milling technique. For example, hard grains like wheat and rye require a more aggressive milling approach to break down their tough outer layers, while soft grains like oats and barley require a gentler approach to avoid over-milling and excessive flour production. A general rule of thumb is to use a 70-80% coarse grind setting for hard grains and a 80-90% fine grind setting for soft grains.

Milling Parameters and Grain Types

Hand crank grain mills can be adjusted to accommodate different grain types by adjusting the gap between the grinding stones or burrs. A gap of 0.5-1.0 mm is suitable for hard grains like wheat, while a gap of 1.0-2.0 mm is suitable for soft grains like oats. The type of grinding stone or burr used can also affect the milling process, with stone mills producing a coarser grind and burr mills producing a finer grind. For example, a 3-inch stone mill can be used for wheat and rye, while a 2-inch burr mill is more suitable for oats and barley.
