ABSTRACT:
A continuous-flow grain steeping and slow grain cooling process and apparatus. The continuous charging of hot, partially dried grain from a heated-air dryer into the top of a grain container in a layer of approximately uniform thickness is accomplished by use of grain spreading equipment. The downward flow of grain through the grain container is regulated by thermostatically controlled sweep and discharge augers located in the bottom of the bin. The grain flows at a rate that allows the grain to remain in a top steeping zone for a predetermined period of time, typically from four to twelve hours. After the initially charged grain is held at the steeping temperature for a predetermined steeping time, a continuous upward flow of ambient air is provided by a fan to cool the grain in a bottom cooling zone. The air flow is controlled by a thermostat to provide air flow at a rate that allows grain to remain in the cooling zone for a predetermined cooling time which is dependent on the airflow rate in cfm/bu. Cooled dry grain from a layer near the bottom is then continuously discharged from the bottom of the grain container by the sweep and discharge augers.
