Abstract

A grain dryer has pair of heating columns in communication with an upper plenum, and a pair of cooling columns in communication with a lower plenum. A heater is located between the lower plenum and the upper plenum, wherein air is heated by the heater as air in the lower plenum is pulled through the heater and into the upper plenum. As the grain flows into the cooling column, it is exposed to cooling air being pulled through the cooling column into the lower plenum. Ductwork adjacent each heating column includes vertical sections arranged along a length of the grain dryer. Each vertical section has a fan located adjacent the uppermost horizontal level of the heating column. Each fan takes a suction from the ductwork to draw heated air from the upper plenum through the heating column.
