PREXA F
PNEUMATIC PRESS WITH OPEN TANK
Pressing has the goal of extracting juice from whole or crushed grapes in the white winemaking process, or the must-wine or wine from fermented grapes, after racking, in the red winemaking process.
This winemaking process must preserve the integrity of the solid parts of the grapes, prevent the breakage of pips, the lacerations of stalks when dealing with non-destemmed grape. In addition, oxidation phenomena must be avoided.
The pneumatic press with a open tank is winery equipment that performs pressing inside a large horizontal cylindrical cage. It uses a membrane that, inflated with compressed air, exerts the necessary pressure on the product to extract the liquid fraction. The wall opposite the membrane and the press door are fitted with slits, through which the must extracted from the pressing flows. Unlike closed-tank membrane presses, cleaning of this wine press is easier, but the must obtained is exposed to air contact.
Designed primarily for the gentle pressing of grapes and the extraction of high quality must, the new generation of Puleo pneumatic presses includes a long series of improvements and options, adaptable to every oenological need.
