<p>This invention discloses an apparatus for continuous drying of particulate materials comprising a perforated board with covered perforations (13) for the passage of the drying medium (8) on which the dried material (3) is placed. The board is made up by a bottom (12) of a drying chute (2) having a rake chain conveyor (4) for advancing the dried material (3) from the input portion (15) of the drying chute (2) to the output portion (16) of the drying chute. The perforations (13) are situated on the lower part of the bottom (12) covered by covering lamellae (14) extending at least to the rims of the perforations (13) directed towards the input portion (15) forming an aperture for passages of the drying medium (8). On the input portion (15) of the drying chute (2) there is a feed hopper (1) with a formatting device (10) to adjust the thickness of the layer of the dried material (3) in the drying chute (2).</p> |
