ABSTRACT:
A gravity-flow grain dryer for particulate material comprises a generally vertical drying column having first and second opposed spaced perforate walls, the column being adapted to receive particulate material and direct the material through the dryer. An input is provided for introducing moist particulate material into a top portion of the column and a discharge mechanism is provided for removing dried particulate material from a bottom portion of the column. A blower and heater are also provided for passing drying air into the column through the first perforate wall and out through the second perforate wall, the air drying the material within the column. A dividing wall extends between the perforate walls for dividing at least a portion of the column into at least two channels, of the channels containing a discharging mechanism for removing particulate material from the channel. A first discharge mechanism is associated with a first of the channels and a second discharge mechanism is associated with a second of the channels, the first channel being adjacent the first perforate wall and the first discharge mechanism is adapted to discharge particulate material at a rate faster than the second discharge mechanism.
