An apparatus is disclosed for drying grain in a storage bin as well as the method of drying the grain. The apparatus includes an air blower positioned outwardly of the storage bin which has an air inlet end and an air discharge end. The air discharge end of the air blower is in communication with the interior of the storage bin. A heat exchanger is positioned in a spaced relationship with respect to the air blower and has an air passageway with an inlet end and an outlet end. The outlet end of the heat exchanger is spaced from the inlet end of the air blower. An infrared heater is spaced from the inlet end of the heat exchanger so that infrared rays from the infrared heater will be directed into the air passageway of the heat exchanger so that the heat exchanger will heat the air being drawn through the heat exchanger by the air blower with the air blower sucking heated air from the air passageway and blowing the same into the storage bin to dry the grain therein. The heat exchanger includes an outer shroud which is trapezoidal in plan view. The heat exchanger includes heat exchanger assemblies which are generally trapezoidal in shape.
