Apparatus for removing at least a portion of the liquid from a liquid-solid mixture in which the liquid-solid mixture is sprayed into one end of a substantially peripherally continuous, moving wall tube and a heated gas is caused to flow through the tube either in the same direction or the opposite direction as the flow of the liquid-solid mixture spray. The tube is formed by moving belts or is a rotatable hollow cylinder, and deposits on the wall of the tube are scraped from the wall by blades or knives. The tube is surrounded by an enclosing tube, and the separated solids, or liquid-solid mixture of lower liquid content, are received in a hopper or on moving belts below the first-mentioned tube from which such solids, or mixture, are removed. After passing through the first-mentioned tube, the gases are vented to the atmosphere or further processed. The apparatus may also be used to remove products of combustion from the gases.
