Fundamentals of grain drying - IRRI Rice Knowledge Bank

As a result, drying rate will decline, and some of the heat from the drying air will heat up the grain. For paddy grain, the falling-rate period typically occurs at around 18% grain moisture content. By using the 18% MC and the drying curve characteristics as a guideline, a few recommendations can be made in regard to grain drying procedures.
