ABSTRACT:
A method and apparatus for drying grain which includes a method and apparatus for unloading the grain from a grain dryer of a type including spaced apart first and second walls for defining a passageway or grain column for directing grain flowing downwardly by gravity between the first and second walls. A substantially horizontal shelf is disposed below the outlet port of the grain confinement walls for receiving grain thereon from the grain column. A channel is disposed below the shelf for receiving grain which is pushed off of the shelf. A discharge port is disposed in the channel. A strip of material is disposed for moving along above the shelf for metering grain from the shelf to the channel as the strip moves along the shelf. A paddle is disposed for movement in the channel for pushing grain from the channel into the discharge port. The dryer also has a central air passage from top to bottom, which lends itself to being used for three mode drying, if desired.
