  • Wheat Drying and Storage - uaex.edu

    Air flow and rate (or velocity) determines the drying time required and the final grain moisture content. Air at a specific temperature and relative humidity continually passing through the wheat will cause the wheat to dry to a specific moisture content since the wheat moisture will eventually achieve a state of equilibrium with the air.
