Heated air, driven through the corn 
and held at a constant temperature of 
110 degrees, reduces the moisture con¬ 
tent to 12%. Drying PIONEER seed to 
this point protects the corn from mold, 
prevents injury by freezing weather 
during winter storage, and gives strong 
germination in the spring. 
Large, portable driers, with oil burn¬ 
ing 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 slatted floors . . . into the corn 
. . . and out through trap doors above 
the corn, liberating about one ton of 
moisture per day. 
Each drying bin holds about 900 
bushels of ear corn which requires from 
24 to 72 hours to dry to 12% moisture, 
depending on the variety of corn and 
amount of moisture it contains when 
harvested. 
Unless good equipment is used and 
supervised by experts, seed corn can 
easily be damaged by improper drying 
. . . PIONEER practices utmost care, 
maintains adequate drying equipment, 
and permits only well-trained men to 
operate the driers.
