ABSTRACT:
A grain dryer which includes a grain column through which grain may flow is disclosed. The grain column includes a left lateral discharge sidewall, a right lateral discharge sidewall, a lower discharge surface and an upper discharge surface which collectively define a discharge opening. The lower discharge surface is spaced apart from the upper discharge surface by a distance equal to D1. The distance D1 is greater to or equal to 5.0 inches. The grain dryer further includes a metering roll positioned to contact grain advancing out of the discharge opening of the grain column. The metering roll has a vane diameter equal to VD. The vane diameter VD is greater to or equal to 6.0 inches.
