Abstract

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 walls (20, 70, 108, 110) with pertorate portions. Drying air is passed through the pertorate portions in a treating zone in the columns (68, 100). 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), re­ spectively. First, second, third and fourth discharge means (84, 82, 126, 124) are also provided for removing particulate material from bottom portions of the first and second drying columns (68, 100), respectively. Associated with the first and second discharge means (82, 84) is a dividing wall (76) which extends between a pair of the spaced walls (20, 70) below the treating zone of the column (68) for dividing a bottom portion of the column into at least two channels (78, 80). The first dis­ charge means (84) is associated with a first of the channels (80) and the second discharge means (82) is associated with a second of the channels (78). The first channel (80) is adjacent the first wall (70) and the first discharge means (84) is adapted to discharge particulate material at a rate faster than the sec­ ond discharge means (82).
