Abstract
Methods for washing sawdust are disclosed which include providing a mixture of sawdust and water to a vessel, subjecting the mixture to a reduced pressure so that gases present in the sawdust cause expansion therein and the sawdust rises to the surface of the mixture while the contaminants descend within the vessel, and withdrawing the sawdust from the vessel, in which the sawdust is withdrawn from the vessel at a location above the point where the sawdust and water enter the vessel. Apparatus for carrying out this method is also disclosed.
