Abstract (en)
[origin: EP0211706A2] 1. A method of separating, by pressing intimately combined liquid and solid fractions in the form of a heterogeneous mixture, such as for example, juices, pulps, kernels, pips stalks and vegetable elements of fruit such as harvested grapes, of the type in which a vessel (14) comprising sidewalls traversed by narrow passages (15) is charged in a so-called "upstream-downstream" direction via a so-called input end with heterogeneous mixture, then the infeed of mixture is interrupted, then a pressing action is induced by effecting a relative linear displacement between the vessel (14) and a non-rotary element (10-13, 103) forming a piston situated before the input end so that this element (10-13, 103) penetrates into the volume (14) from upstream to downstream, characterised in that an opposing retaining force, that is to say directed from downstream to upstream co-axially with the vessel (14), is engendered at its so-called outlet end opposite the preceding end and acting on the fractions of heterogeneous mixture fed in, which are thus agglomerated progressively into a cake of solid fractions, whilst forming an annular outlet space, also coaxial, whereupon after the pressing of the heterogeneous mixture simultaneously causing the emergence of at least a part of the liquid fractions through the walls of the vessel (14) and the discharge of a part of the cake of solid fractions through the outlet space, the relative linear displacement is then stopped, after which a renewed input of mixture is effected and its pressing in the vessel (14) is effected at a pressure matched to the value of the outlet retaining force and so on in successive cycles.
