Abstract (en)

A gravity-flow grain dryer (10) for particulate material comprises first and second generally vertical drying columns (68, 100) spaced apart to provide a plenum chamber (112) therebetween, the drying columns each having opposed spaced perforate walls (26, 70, 108, 110). First and second inputs (32, 72, 90, 96) are provided for introducing particulate material into top portions of the first and second drying columns (68, 100), respectively. First and second discharge means (82, 84, 124, 126) are also provided for removing particulate material from bottom portions of the first and second drying columns (68, 100), respectively. The first discharge means (82, 84) includes a dividing wall (76) which extends between the perforate walls (26, 70) for dividing at least a portion of the column into at least two channels (78, 80), both of the channels containing a discharging mechanism (82, 84) for removing particulate material from the channel. A first discharge mechanism (84) is associated with a first of the channels (80) and a second discharge mechanism (62) is associated with a second of the channels (78), the first channel (80) being adjacent the first perforate wall (70) and the first discharge mechanism (84) is adapted to discharge particulate material at a rate faster than the second discharge mechanism (82). Conveyor means (90) is provided for receiving the particulate material discharged from the first drying column (68) and for conveying the particulate material to the second input (96). A flow of drying air is directed to the plenum chamber (112), whereby the drying air passes into the first and second drying columns (68, 100) to dry the particulate material, the drying air being subsequently discharged from the drying column.
