Ken Hellevang, NDSU Extension agricultural engineer, offers the following tips and reminders for handling wet corn.
Don't put corn exceeding 23% moisture in a grain bin because the kernels may freeze together or deform and bind together, which could keep them from flowing from the bin during unloading. It should be place in a building or pile so that it can be moved a front-end loader or other equipment that can dislodge the corn mechanically.
Aerate the pile to keep the corn from deteriorating rapidly. Without airflow through the corn, temperature will increase quickly, resulting in rapid deterioration. An airflow rate of 0.2 cubic feet per minute per bushel of stored corn is recommended.
Open bin covers when operating fans when the temperature is near or below freezing. There were numerous reports last year of bin vents freezing over and the fan pushing the roof up and damaging the bin roof.
Screen-clean wet corn to remove fine material, cob pieces and broken kernels before putting it into a bin. Fines spoil faster than kernels. They also have higher airflow resistance.
Cool grain to about 20 to 25 degrees F. Corn with damage to the seed coat and immature corn have a shorter storage life than mature corn.
