Abstract
Abstract The wine making process comprises the maceration stage taking place at an intensive rate, due to the continuous and violent recycling of the must over the pressed grape dregs. The plant for carrying out the process comprises a vat; a torque flow pump connected by means of a pipe provided with a valve, to the base of the vat; a sprayer with differentiated arms, rotating by reaction, situated in the top part of the vat and connected to the pump outlet.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
144 words
A wine-making plant comprising at least one vat, a torque flow pump connected to a feed pipe leading to said vat; a sprayer with discrete arms, rotating by reaction, situated in the top part of the vat and comprising a plurality of L shaped tubes of various lengths connected, by means of a locating flange to a central cylindrical body, an upper closing flange carried by said body which rotatably rests on a centering and thrust bearing carried by said feed pipe; a further ring of elastic material situated in the lower zone of contact between the cylindrical body and the end of the feed pipe; a suction pipe, provided with a valve which connects the base of the vat to the pump inlet; and a pipe provided with a valve which connects the pump outlet to the inlet of a trickle pressing plant.
Claim 2
Dependent Claim
144 words
A wine-making plant comprising at least one vat, a torque flow pump connected to a feed pipe leading to said vat; a sprayer with discrete arms, rotating by reaction, situated in the top part of the vat and comprising a plurality of L shaped tubes of various lengths connected, by means of a locating flange to a central cylindrical body, an upper closing flange carried by said body which rotatably rests on a centering and thrust bearing carried by said feed pipe; a further ring of elastic material situated in the lower zone of contact between the cylindrical body and the end of the feed pipe; a suction pipe, provided with a valve which connects the base of the vat to the pump inlet; and a pipe provided with a valve which connects the pump outlet to the inlet of a trickle pressing plant.
Claim 3
Dependent Claim
75 words
A plant as claimed in claim 1 in whiCh the sprayer comprises two or more rotors with discrete arms mounted at the ends of a like number of substantially horizontal tubular arms branching from a single central manifold which in its turn is rotatable about a stationary manifold attached to the center of the lid of said vat and into which at least one delivery pipe from at least one pressed product recirculation pump feeds.
Claim 4
Dependent Claim
72 words
A plant as claimed in claim 2, in which the mobile manifold is rotatably connected to the stationary manifold by means of an upper flange on the mobile manifold which rests on a thrust bearing supported by a ring nut screwed on to the fixed manifold; a seal between the two manifolds being provided by a ring of a suitable synthetic material inserted in a cavity formed in one of said manifolds.
Claim 5
Dependent Claim
49 words
A plant as claimed in claim 3, in which said mobile manifold is driven by an electric motor through a worm which engages a gear wheel mounted on pivot means which traverses both the fixed manifold and mobile manifold and is fixed to the bottom of the mobile manifold.
Claim 6
Dependent Claim
34 words
A plant as claimed in claim 1, characterized in that the pump motor is adapted to rotate the pump at high speed during a spraying stage and at low speed to empty the vat.
Claim 7
Dependent Claim
15 words
A plant as claimed in claim 1, in which there are at least two pumps.
Claim 8
Dependent Claim
40 words
A plant as claimed in claim 6, in which the suction pipes of said pumps extend inside the bottom of the vat and are provided with a number of underlying intake holes uniformly distributed over the bottom of the vat.
