Abstract

The present invention concerns a multistage, continuous pneumatic (10) press to separate a liquid fraction from a solid fraction, preferably to separate the juice of whole, trimmed or pressed fruit. The device comprises a long vat (11) which should have a cylindrical shape and which rotates around its longitudinal axis. The vat presents a material adduction port with an axial opening at one end (19). The material to be pressed is continuously introduced through said opening into said vat (11) together with a fluid kept under pressure. At the other end (20) of the vat there is an axial opening for continuous evacuation of the pressed material. Said vat (11) is provided with at least three operational units that are set along the material direction of travel, more precisely they are a non-press draining unit, a pressing unit which is provided with membranes (32), wherein said membranes are actuated at increasing pressure levels, and finally an evacuating unit for the solid material, said vat (11) being provided with an internal draining system (22) that co-operates with the separation devices (26, 27) for the separated juice.
