Closed Pressing System

Half of the press drum is covered by an impermeable membrane, while there are perforated draining channels all along the other half. A built-in compressor is used to establish the desired pressure within the drum. This inflates the membrane, which consequently presses the grape mass and drains the must. Must then flows through draining openings into a collection pan. Soft grape and grape pomace membrane pressing with compressed air prevents any mechanical damage to the grapes, thus ensuring a production of high-quality must and wine.

The draining channels are electropolished. Advantages of an electropolished surface:

  • reduced grape pomace sticking to the drum surface, which means better must flow through drainage holes,
  • easier drum cleaning, reduced water consumption,
  • surface looks glossy and shiny,
  • reduced possibility of coating on the material,
  • increased corrosion resistance of the material.

Grape presses with a closed pressing system can also be used for grape pomace fermentation and maceration inside the drum. In this case, it is recommended that the press drum also be equipped with a cooling jacket (pillow plate).

The main advantage of a closed pressing system is a reduced possibility of must oxidation.
