<p>Such improvements consist in using as arm (2) of the machine for loading and unloading the vat, a hollow and hermetically sealed element to which compressed air from a generator (10) has access, which is channelled through a series of vertical uprights (6) to lower heads (11) connected in their turn to the said uprights, elongated, in such a way as to align radially playing on all of the base (3) of the vat and lateral air-exit slots extending in these heads (11). In this way a radial air-curtain is formed which, on rotating the arm (2) of the loading/unloading machine, circumferentially sweeps the whole bottom of the vat and consequently stirs, oxygenates, cools and, if relevant, displaces the CO2 from the whole mass of grain, in a uniform way. <IMAGE></p> |
