Abstract

The invention relates to a device for pressing grapes comprising a tank (2) having a body (4) with a profiled overall shape along a horizontal longitudinal axis, a front face (6) and a rear face (8) closing the end of the tank body (4). The tank (2) contains two parallel side walls (14) each extending vertically from the front face (6) to the rear face (8). The body (4) comprises an opening (10) in an upper portion of the tank body, the opening (10) allowing the insertion of grapes between the two side walls (14). The tank (2) further comprises a plate (12) extending horizontally from one side wall (14) to the other and from the front face (6) to the rear face (8), the plate (12) being movable between the two side walls (14). The plate (12) and/or the side walls (14) have at least one zone with a grid structure.

Abstract

The invention relates to a device for pressing grapes, which is intended to cooperate with a tank and has: -- a first plate (24) having a first face, or upper face, and a second face on the opposite side from the first face, or lower face, said first plate (24) having a contour adapted to the shape of the tank, - a second, perforated plate (26) that is disposed opposite the second face of the first plate and has a second-plate contour adapted to the interior of the tank, - mechanical connection means between the first plate and the second, perforated plate, and - drive means for moving the second plate in translation towards the first plate. The invention also relates to a winemaking system implementing such a pressing device. The invention also relates to a winemaking method implementing such a winemaking system.
