Abstract

Wort collector device adaptable to a horizontal press comprising a cylindrical tank (1) whose semi-cylindrical upper part (10) is hermetic and the semi-cylindrical lower part (11) is perforated. This device is substantially semi-cylindrical and consists of two quarter-cylindrical half-collectors (2, 3) fixed bilaterally to said tank (1) at the level of the border between its upper part (10) and its lower part (11), so as to be able to open or close on the lower part (11) under the effect of jacks (20, 30) whose rods apply to said half-collectors (2, 3) not far from their line of junction, each half-collector (2, 3) having internally, on each of its two longitudinal edges, a channel (22, 23), respectively (32, 33), one of which (22, 32), close to the junction line of the two half-collectors (2, 3) is extended at one of its ends by an evacuation pipe (21, 31), the whole being covered with a membrane (24, 34) fixed hermetically on the edges of said half-collector (2, 3) and in which an opening is provided for the discharge pipe (21, 31).

Description

The object of the present invention is a device for collecting the must.

  resulting from the pressing of the grapes, adaptable in particular to a horizontal press that is pneumatic or otherwise. The horizontal presses known to date generally consist of a horizontal cylindrical tank whose lower semi-cylindrical part comprises a multiplicity of orifices, especially slots, and on its inner wall, drains extending horizontally parallel to the axis of the vat The grape to be squeezed is placed in this perforated lower part and covered, in the case of a pneumatic press, with a membrane, then with air blown between this membrane and the upper wall of the vat, applying a pressure on said membrane and thus compressing the grapes whose juice flows through the drains to be collected in a tray. The tank is rotated about its axis to allow loading of the grapes and evacuation of

  residues easier by the doors with which it is equipped.

  The must being very sweet, the sugar is deposited in the orifices of the openwork part and drains, making it necessary to clean them, a difficult operation, particularly with regard to the drains.

  inside the tank, which is long and inconvenient.

  Some tanks are equipped with an automatic drains cleaning device that consists of a series of water inlet pipes, one per drain, which complicates the installation, stresses its manufacturing cost and increases the risk of breakdowns

and leaks.

  The present invention overcomes these various disadvantages by providing a must collector device which is easy to clean and which also offers the advantage that the must at the outlet of the tank is not in contact with

1 air.

  The mash collection device object of the present invention fits on a tank similar to those of known presses, having a perforated semi-cylindrical lower portion and a hermetic upper portion, rotatable about its axis and provided with loading doors and

  but with no internal drains.

  According to the invention, the wort collector device which is the subject thereof comprises a semi-cylindrical collector fitting on the perforated lower part of the vessel and composed of two quarter-cylindrical parts, each articulated on the vessel at the border between the upper part and the perforated lower part Thus the collector can open in two, under the action of jacks whose stems

  apply not far from the junction point of the two half

  collectors, and be kept closed and tight on the lower part of the tank by means of these same cylinders, each half-collector coming into contact with the tank only by its

  edges lined with a peripheral seal.

  According to the invention, each half-collector has, in addition, on each of its longitudinal edges, two longitudinal cutouts forming channels.

  one of which, close to the junction line of the two half

  collectors, at their lowest point, is extended to one of

  its ends by a drain pipe.

  A food grade membrane is placed in each demicollector and sealed to the edges thereof, but having an opening at the drain pipe. When the collector is closed on the tank, the two membranes of the half-collectors are flush with the lower perforated portion of said tank, and when the pressing operation is launched, the juice of the grape passes through the orifices of the tank and, under the juice push, the membranes deform and follow the inner shape of the half-collectors, including channels, allowing the juice to flow to the evacuation pipes, without being in contact with the air. Once the pressing is done and the residues evacuated, simply open the collector to gain access to the membranes, which can be cleaned by means of a jet of water. The advantages and features of the present invention will emerge more clearly from the

  description which follows and which refers to the annexed drawing,

  which represents a non-limiting embodiment thereof.

  In the appended drawing: FIG. 1 represents a perspective view with partial cutaway of a horizontal pneumatic press.

  equipped with a must collector according to the invention.

  Figure 2 shows a sectional view of the same press according to the plane A of Figure 1, before the pressing operation. Figure 3 shows the same sectional view

during the pressing operation.

  FIG. 4 represents a sectional view of the same press, according to the plane B of FIG. 1, during the operation

pressing.

  Referring to FIG. 1, a horizontal pneumatic press can be seen comprising a tank 1 formed of two parts, an upper part 10 provided with loading and evacuation doors 13, and a perforated lower part 11 pierced with a multiplicity This tank 1 is mounted so as to rotate about an axis 14 making it possible to

  position the doors as favorably as possible 13.

  A substantially semi-cylindrical collector 1 'fits on the perforated bottom portion 11 of the tank 1, consisting of two collectors 2 and 3 fixed, by means of hinges 16, to the tank 1, the opening maneuver and closing the half-collectors 2 and 3 is effected under the action of two pairs of cylinders 20 and 30 disposed at both ends of the vessel 1, and one of which is not visible in the figure. With reference to FIG. 2, it can be seen that each half-collector 2, 3 is in contact with the vessel 1 only

  by a seal 25, 35, filling its edges Each half

  manifold 2, 3, internally comprises two longitudinal channels 22, 23, respectively 32, 33, the assembly being covered by a membrane 24, 34, hermetically sealed to the edges of said half-collector 2, 3, this membrane 24, 34 being in close contact with the perforated bottom portion 11 of the vessel 1 when the half-collectors 2 and 3 are closed on said vessel 1, after the grape 4 has been introduced into the vessel 1

  by the doors 13, then covered with a membrane 15.

  Referring to FIG. 3, it can be seen that, to press the grapes 4, air is injected, represented by the arrows, between the membrane 15 and the wall of the upper part 10 of the tank 1. The grape is compressed between the membrane 15 and the perforated wall of the lower part 11, and the juice flows through the orifices 12 of said lower part

  11 Under the pressure of the juice, the membranes 24 and 34 of the half

  collectors 2 and 3 are deformed and take the inner shape of said half-collectors 2 and 3, and in particular channels

  longitudinals 22, 23, 32, 33, in which the juice flows.

  Referring now to FIG. 4, it can be seen that the juice that flows on the membranes 24 and 34, respectively in the channels 22 and 32, is evacuated by evacuation pipes 21 and 31 which extend said channels 22 and 32 are connected at their ends, the membranes 24 and 34

  comprising at this point an opening 24 ', respectively 34'.

  To clean the half-collectors it is sufficient to open them by means of the jacks 20 and 30: this gives access, on the one hand, to the perforated lower part 11 of the vessel 1

  and on the other hand to membranes 24 and 34.

  It goes without saying that the present invention can not

  be limited to the foregoing description of one of its modes of

  realization, likely to undergo a number of

  modifications without departing from the scope of the invention.
