|TYPICAL CAPACITIES/HR||1 bin fill per harvest season up to 31,900 bu./year using a 48’ 6 ring 4.00” bin|
|Operation Type||Near Ambient High Airflow Drying|
|Fuel||LP or Natural Gas|
|Electrical||1 and 3 phase|
To assure success the grain depth must not exceed 21’ (6.4 m) not counting the plenum area of the bin. The airflow per bushel must be at least 1 cfm/bu. when the bin is level full. Static should be no more than 6”-6.5” (152.4-165.1 mm) so that the temperature rise can be provided with the burner not heat from pressurized air. A Humidistat reading the air in the plenum of the bin is the minimum to keep from over drying the lower portions of the bin.
A stiffened GSI bin no larger than 48’ (14.63 m) and 6-rings tall gives more protection against bin damage. To reduce time spent managing the system, an automatic fan control system can be added. It operates by monitoring the ambient temperature and humidity while controlling the fan and heater to only run when conditions are right and provide heat only when necessary.
