Abstract
A method of separating solids and liquid material in a slurry. The solids are continuously purged, washed, dried and removed with a minimum amount of mechanical handling. The slurry is continuously deposited on a moving horizontal rotary screen and condensible vapor is introduced above the layer while the pressure is reduced below the layer. Liquid is withdrawn from underneath the slurry layer with the vapor passing through the layer becoming superheated upon passage to evaporate further liquid from the solids. A stream of gas, which may be the same condensible vapor, is directed at the solids to entrain them and remove them from the screen.
