¢ÅFeeding. Will contain solidly with the spiral conveyer rate will be 15%-30% dehydrated sludge delivers to the water extractor import, sometimes will be able to act according to the sludge the nature. Chooses will sieve whether the tiny desiccation sludge with will wait the desiccation the sludge to carry on the premix. 
¢ÆHeat source production. May use the hot steam or the hot painter's shop for the heat change heat source. The general thermal fluid temperature is 180¡æ-200¡æ.The hot medium is introduced separately the spatial dryer shell and the rotation axis thick liquid leaf and so on possesses with the sludge contact carries on the heat change the heating metal surface.
¢ÇThe sludge is dry. The heating metal surface and the sludge uniform contact, in the heating sludge evaporation sludge moisture content, along the dryer axial length, the steam sends can experience the constant rate of evaporation and the low rate of evaporation two stages, the sludge desiccation experience plasticizing, broken models, the block, the pellet 4 steps, the sludge temperature assumes the fast rise, stable, fast rise tendency, finally exports the sludge temperature for 100¡æ-110¡æ about, exports the sludge to reach above 90% including the solid quantity. 
¢ÈCooling screening. Cooling has direct cooling and cools two ways indirectly, two ways enter the thin grill to carry on the screening, or after the molding machine achieved requests dry sludge shape.
¢ÉCondensation recycling. In the water extractor hot steam delivers to condenser condensation processing, the condensation solvent recovery, cannot congeal the gas to deliver heats up the heat source again to the boiler, the condensed water returns to the sewage treatment plant.
