Abstract
In the pressing of liquids from solid materials, especially for the pressing of liquids from oil-containing solids such as edible-oil seeds, using a filter press, the pressing is carried out in a plurality of stages each of which is followed by a pressure reduction. According to the invention, the material in each stage is initially subjected exclusively to a progressively increasing pressure, is then spontaneously expanded to the ambient pressure and thereafter is at least partially subdivided into particles which are compressed in the next stage in accordance with the same pressing sequence.
