(57) A grape press constituted by a cylindrical or truncated-cone tank (3) provided with
a series of semi-elliptical partitions (11) adapted to form, together with respective
membranes (15), a plurality of pressure chambers (13). Successive pressing regions
(23, 25, 27), with related discharge devices (21, 31, 33, 35), are arranged parallel
to the pressure chambers. The product is fed continuously at one end of the tank and
is advanced by rotating the tank, since the partitions are arranged so as to form
a half-helix. The pressure chambers and the pressing regions are actuated alternatively
in order to perform the intended pressing cycles.
