The invention relates to a process, a device and a press for reducing the water content, bound by capillarity in fibre cells, of pulverized solid carboniferous materials and/or sludges, especially raw lignite. For large-scale industrial use of raw lignite by means of thermomechanical dewatering with better overall efficiency during flow throughput in large power plants, the process of the invention consists of a combination of the following process stages: a) an feed material preheated to approximately 60° Celsius is used, which at the beginning of the operating cycle is steamed from both flat sides in an essentially vapourtight pressure chamber, closed off and preheated to 100° Celsius, with water vapour superheated to 150° Celsius, while b) the compressive pressure on the feed material the pressure in the feed material due to bulk density, is at the maximum approximately equivalent to the introduced steam pressure of 5 bar to 8 bar, and c) after a temperature of approximately 125° Celsius is reached in the feed material, the injection steaming is terminated and, depending on the granular size of the feed material, a high mechanical, specific pressure in the press up to a maximum of 75 bar is used for reduction to a residual water content of up to 20 percent by weight.
