Drying wheat and barley - University of Minnesota

2021-12-28  If you harvest grain at high moisture content, you need to artificially dry it to 13 to 14 percent moisture for safe storage. Crop producers sometimes harvest wetter-than-usual grain to reduce harvest losses or because of wet weather. There are two basic types of grain dryers: Dryers that use no heat (natural-air dryers) or very little heat (low-temperature dryers).
