The wet milling process involves using water to break down grains prior to milling. This allows the individual parts of the grain to separate from one another for easier harvesting. The wet mill process is a common method of harvesting grain for food components, but dry milling is more common for flour or ethanol production.

If you were to calculate bushel yield, it would be 2.22, since 450,000 pounds equals 4,500 cwt and 10,000 bushels divided by 4,500 cwt equal 2.22. The lower the bushel yield the more efficient the milling process. Extraction is simply calculating the percentage of flour produced. For instance, 10,000 bushels equals 600,000 pounds of wheat (at ...
