<p>A vertical grape press, of those having a general constitution basically made up of a vat (1) receiving the grape mass (4) to be pressed, a vertically displaceable plate-piston (2) closing the vat (1) on the upper end, and a must collection tray (3) closing this vat (1) on the lower end, the vertical press being characterised in that between the plate-piston (2) and the grape mass (4), there is a flexible resilient roof (5) covering the entire surface of this grape mass (4) and which has adjustable fluid drive means associated thereto capable of displacing it against said grape mass (4) to be pressed; and a pressing process carried out with a fluid-driven flexible resilient roof (5) which is actuated in one or several successive repetitions. <IMAGE></p> |
