Abstract: An apparatus for controlling grain flow within a column of a grain dryer is disclosed. The grain dryer includes a metering roll positioned to contact grain advancing out of a discharge opening of the column. The grain dryer further includes a regulator member which is movable between a flow regulating position and a trash escape position. The regulator member contacts either the metering roll, or grain supported by the metering roll when the regulator member is positioned in the flow regulating position. The regulator member is spaced from the metering roll by a distance sufficient to enable a trash object to advance between the regulator member and the metering roll when the regulator is positioned in the trash escape position. A method of controlling grain flow within a column of a grain dryer is also disclosed.

Abstract: A grain dryer which includes a grain column through which grain may flow is disclosed. The grain column has a discharge opening. The grain dryer further includes a metering roll positioned to contact grain advancing out of the discharge opening of the grain column and a grain support member interposed between the metering roll and the discharge opening, the grain support member defining a substantially planar top surface. Rotation of the metering roll causes grain to advance out of the discharge opening, over the substantially planar top surface, and into contact with the metering roll. An angle .THETA. is defined between a line L1 defined by the substantially planar top surface and a horizontal line HL which intersects the line L1. The angle .THETA. is greater than or equal to 0.degree., but less than or equal to 30.degree..

Abstract: A grain dryer which includes a grain column through which grain may flow is disclosed. The grain column has a discharge opening. The grain dryer further includes a metering roll positioned to contact grain advancing out of the discharge opening of the grain column and a grain support member interposed between the metering roll and the discharge opening. The grain support member being movable between a grain support position and a cleaning position. The grain dryer yet further includes a transport bin positioned below the metering roll. The grain support member directs grain flowing out of the discharge opening to the metering roll when the grain support member is positioned in the grain support position. The grain support member directs grain positioned on the grain support member to advance under the metering roll and into the transport bin when the grain support member is positioned in the cleaning position.

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.
