PCT No. PCT/CA94/00580 Sec. 371 Date Apr. 18, 1996 Sec. 102(e) Date Apr. 18, 1996 PCT Filed Oct. 18, 1994 PCT Pub. No. WO95/11416 PCT Pub. Date Apr. 27, 1995The apparatus includes a channel having an inlet end for receiving particulate material to be dehydrated and an outlet end for discharging the particulate material in a dehydrated condition. A screw conveyor rotatably mounted in the channel advances the particulate material while stirring the particulate material to enhance the release of water and noxious vapors. A fan creates an air current in the channel to entrain water and noxious vapors released by the particulate material. The vapors are directed toward a heating chamber which incinerates dangerous and odoriferous compounds as much as possible. The resulting gaseous media is directed through a passage in a heat-exchange relationship with the channel to elevate the temperature of the particulate material that is being processed and to cause same to release water and noxious vapors. The passage is isolated from the channel to avoid direct contract between the burned gases that are released in the atmosphere with yet unburned gases aspirated from the channel. |
