A better way to accomplish this, if possible, is to periodically unload some grain as you fill the bin. $59.00. In bins without cables, use thermometer probes to check the temperature at different locations within the bin. Although stored grain can and is being aerated with airflow rates as low as 0.03 to 0.02 cfm/bu in commercial storages, a minimum of 0.1 cfm/bu is recommended for on-farm grain storages because it’s an easily attainable airflow level. These small fans move low volumes of air at low to moderately high static pressures, so they are ideal for aeration with deep grain depths. Air for grain cooling. This is best done in several stages by starting early – end of March or first of April – and running the fans night and day in fair weather when the average 24-hour temperature is 10 degrees warmer than the grain. However, research shows that distributing fine particles throughout the bin increases the resistance to airflow, which reduces airflow. We’ll discuss the aeration management schedule for each of these periods. Nickname. 37.)
