Provided is a reactor having: 1 a housing inlet means for admitting therein a particulate material to be heat treated and an outlet means for discharging the heat treated material, 2 at least one tray disposed horizontally inside the housing between the inlet and outlet means and having a support surface for supporting a bed of the particulate material, 3 a heating means for heating the bed of particulate material on the support surface, and 4 a conveyor system for moving the bed of particulate material while being heated along a predetermined direction on the support surface. The conveyor system includes a plurality of horizontally spaced-apart rake members extending across the support surface transversely of the predetermined direction and each having a plurality of spaced apart fingers in sliding contact with the support surface, and means for moving the rake members to displace with the finger the particulate material along the predetermined direction, the fingers of any one of the rake members being misaligned with the fingers of any other one of the rake members and being displaced relative to one another such the at the fingers rake across substantially the entire support surface of the tray and constantly stir the particulate material which displacing same, thereby constantly exposing the fresh surfaces of the particulate material to heat and increasing heat transfer in the bed. |
