After the first hot grain delivered to the bin. The grain is cooled and 1 to 2 percent moisture content removed by airflow before it is moved to final storage. Cooling is normally completed about six hours after the last hot grain is added if the cooling rate equals the filling rate. Grain is dried to the desired moisture content for storage in the dryer, then moved to storage where it is cooled. Schematic of in-storage cooling.
Grain is dried in a high speed dryer to safe storage moisture content.
The hot dry grain is then moved to storage where it is closed. Tempering For Dryeration Immediately after high-speed high temperature drying, the inner portion of a kernel is wetter than the outer portion. During the tempering process the moisture equalizes throughout the kernel. Some moisture is then removed during the slow cooling process of dryeration. In contrast, little moisture is removed during rapid cooling.
