Aeration of Corn and Soybean after drying
Dried corn and soybeans are meant to be aerated immediately after they are filled in the permanent storage structures or the storage bins for an effective grain temperature monitoring system . In upright bins, there is a need for aeration systems that must be designed for generating nothing less than 1/7 to 1/10 cubic feet of air per minute per bushel (CFM/bushel). This will allow the cooling fronts to move through the corn and soybean mass in a minimum time period of 105 to 150 hours. When the depth of the grain when storing exceeds 50 feet (15 meters) such as in the case of the tall concrete silos, then the airflow rates of 1/20 to 1/40 CFM/bushel should be selected to overcome extreme static pressure and horsepower conditions using the EndZone Fan Controls. These rates will help in resulting in the cooling fronts to move through the grain mass of corn and soybean for a minimum of 300 to 600 hours. However, when the grains are stored in flat storage sheds, then the airflow ra...
