Abstract
In supplying material for pressing (37) into the press chamber of a filter press for separating solids and liquids, the filling operation (F) is done interruptedly in a first step (P1) at a fill opening (44). A press element (36) executes a plurality of pressings up to a constant stroke position (HS). Not until a second method step (P2) is the filling operation (F) interrupted, as soon as the pressing pressure exceeds a limit value (PS), whereupon the pressings are continued with shortened strokes. The method offers automatic adaptation of the prefilling time to the pressability of the materials. It thus becomes possible to prefill highly differently pressable material automatically and without specifying a command value in such a way that an optimal performance is attained in terms of the yield and the juice extraction output of a filter press.
