ABSTRACT:
A dryer for particulate material, especially wood chips, to render them suitable for burning comprising an enclosure, spaced baffle plates in the enclosure dividing the enclosure from bottom to top into three chambers; an intermediate drying chamber for holding a column of particulate material for drying and two air chambers, one on each side of the drying chamber. The baffles contain openings, the air chamber at one side contains a bottom opening through which drying air is supplied to the enclosure and the air chamber at the other side contains an opening at the top through which moist air is discharged from the enclosure. There is a conveyor at the upper end of the enclosure for supplying particulate material to the upper end of the drying chamber, a discharge opening at the bottom of the enclosure for permitting discharge of the particulate material from the lower end of the drying chamber and an oscillator for at times effecting oscillation of the baffle plates to, in turn, effect discharge of particulate material through the bottom opening.
