After the sorted corn has been re-examined by the checkers, it is conveyed to large bins 
. . . with slatted floors. Large, portable driers with oil burning furnaces and electrically 
driven pressure fans . . . force hot air uniformly through every part of the drying bins 
. . . at the rate of 46,000 cubic feet per minute. The warm air circulates upward through 
the slatted floors . . . into the corn . . . and out through doors above the corn. 
The moisture content of all Pioneer corn is reduced to 12 percent before it is removed from 
the bins . . . to be shelled.

2,000 to 2,500 men, women, girls and boys are employed in Pioneer plants
