1. Method for filtering a suspension in a filter device, the filter device having between a stationary head piece and a movable end piece a pack of at least a first recess plate having a first recess and/or a second recess plate having a second recess, the first recess and/or the second recess forming a filter chamber between the first recess plate and the second recess plate, and the filter device having two filter cloths between the first recess plate and the second recess plate for filtering a solid content out of the suspension as a filter cake, and the first recess plate having a first duct towards a first outlet and the second recess plate having a second duct towards a second outlet, the method comprising a sequence of steps, including
a. piping the suspension into the filter chamber between the filter cloths, b. directing the suspension through the filter cloths, such that the filter cake settles between the filter cloths, c. discharging a liquid fraction of the suspension through the first duct and the second duct out of the filter chamber and through the first outlet of the first recess plate and the second outlet out of the second recess plate as a filtrate, and d. piping a drying gas from the head piece into the filter chamber through the first duct and discharging the same through the second duct, characterized by discharging the drying gas straight from the second duct to the ambience. |
