Definitions

  • the present invention relates to the field of techniques for the extraction of juices from materials, such as grape harvests, more particularly processes for treating the materials to be pressed, and relates to a process for management of drainage and pressing, in particular for a tank press rotary.
  • Simple mixing of the materials to be pressed followed by draining static can be more productive in extracted liquid than a rise in pressure applied to these materials.
  • the present invention therefore proposes to automatically choose the the most productive operating mode, between static drainage and applying pressure to the material to be pressed.
  • the present invention relates to a draining and pressing management process, in particular for a wine press rotary tank, as described below.
  • the method of managing the draining and pressing consists, following a first phase of stirring of the materials to be pressed by means, for example, of one or more rotations of the press tank, to perform a first measurement phase without applying pressure or by applying pressure Po and by measuring the instantaneous flow of the juice D it and the quantity Q jt of juice recovered as a function of time t elapsed since the start of brewing, continuously or sequentially over time, then to carry out, following a second brewing phase, a second consecutive measurement phase by applying a pressure P o or without applying pressure, to be compared between them the respective values of D it , Q jt and t reached when the inequality: D it ⁇ Q jt / t (1) is verified for the first time in said first and second above-mentioned measurement phases ées, that is to say by applying a pressure P o and without applying pressure, and to continue depending on the result of this comparison the operation of the press either by continuing
  • no pressure is not applied during the first measurement phase and a pressure Po (for example 0.1 bar) is applied during the second measurement phase.
  • a pressure Po is applied during the first measurement phase and no pressure is not applied during the second measurement phase.
  • the drip and pressing tests can be done in any order, as long as they are always done consecutively one after the other, each time being preceded by a phase of identical brewing.
  • checking the inequality (1) can also indicate, during a draining phase, that the continuation of the draining phase currently in progress does not allow a maximum quantity of juice to be recovered, and that it is necessary to carry out a new mixing of the materials to be pressed to restart the flow of juices.
  • the verification of the inequality (1) during a phase of pressing may also indicate that the continuation of the pressing phase is not optimal and that the materials to be mixed must be mixed press and continue, if necessary, with a pressing phase at one higher pressure.
  • the various functions that are part of the management process are executed automatically by a processing and computer control unit, using software and corresponding programs loaded beforehand, as well as possibly the numerical results of tests and experiments drainage and pressing.
