Zusammenfassung:	A process and apparatus for removing moisture from sludge. The process and apparatus comprise: conveying on a conveyor the sludge on an incline through a housing such that, as the sludge is conveyed, it is deposited onto an exposed portion of the housing; heating the sludge with a heater as it is conveyed on the incline to evaporate moisture in the sludge, whereby the sludge that it is deposited onto the exposed portion of the housing is also heated to thereby evaporate moisture from the sludge; extracting from the housing using a vacuum device an airflow comprising the evaporated moisture, whereby the airflow includes moisture that has been evaporated as a result of the sludge being deposited onto the exposed heated portion of the housing; and discharging from the housing, separately to the extracting of the airflow from the housing, the sludge from which the moisture has been removed.
