A bin contains 600,000 lb of corn at 18% moisture. A fan delivers 20,000 cfm to this bin. Ambient air is at 52 F dry bulb and 30% relative humidity. Power input to the fan causes an 8 F temperature rise to the air.

a. To what moisture content will the system dry the corn?

b. How long can be allowed to dry corn without spoilage?

c. Assuming air conditions stay the same, what is the minimum airflow rate (cfm) which would complete drying within the Shelled Corn Storage Time (SCST)? d. How many days of the SCST were lost due to the 8o F temperature?
