摘要

The movable device comprises a frame, a counterweight unit (12), a rolling unit (14), and a pressing unit (16). The marc has a tendency to form a cap layer on the juice. The counterweight unit is associated with the frame, and comprises a volume to be filled with a liquid. The volume comprises annular hollow body (20) forming a ring equipped with a unit for filling a liquid and a unit for emptying the same liquid. The pressing unit comprises a blade, and a unit to operate the blade. The blade comprises two half-discs forming two flaps articulated around a horizontal center line to fold. The movable device comprises a frame, a counterweight unit (12), a rolling unit (14), and a pressing unit (16). The marc has a tendency to form a cap layer on the juice. The counterweight unit is associated with the frame, and comprises a volume to be filled with a liquid. The volume comprises annular hollow body (20) forming a ring equipped with a unit for filling a liquid and a unit for emptying the same liquid. The pressing unit comprises a blade, and a unit to operate the blade. The blade comprises two half-discs forming two flaps articulated around a horizontal center line to fold, which is bounded downwards and equipped with an abutment unit for stopping the flaps to fold upwards. The unit for operating the blade comprises a pneumatic cylinder, a body and a rod. The body of the cylinder is mounted on a cradle (22) formed in the frame by its end for guiding the shaft, and the other end of the body is connected to the frame by ropes. A rod is oriented downwards for carrying the blade. The rolling unit is connected directly on the frame, and comprises arms at the end from which rollers are connected. The rollers are rotatable at 360[deg] and equipped with a unit for blocking the rolling. A retractable tray is arranged for collecting flows after the action of pressing during shifting. The tray is hinged to be fixed in two positions in a horizontal plane, in which the first position is used for collection and located under the pressing unit and the second position is used for holding and retracted for passing the pressing unit.
