Design features & benefits of central membrane press technology

摘要

WINEMAKERS AGREE that the more rapid the grape juice is separated and drained from the polyphenol oxidase enzymes a lower concentration of browning fractions and oxidation occurs. It would hold then that a juice extraction design that more effectivelyefficiently ensures juice separation would be the press of choice for winemakers.By virtue of the membrane press bag in any side bag press design taking up 50% of the tank surface area, little surface remains for drainage screens with side bag press designs by comparison to a design where by the whole tank surface is covered by drainscreen. Take into account loading doors the typical drain screen surface available for side bag presses is only 22% - 24% of the press tank surface. When compared to the Delia Toffola press design which provides 88% of its tank surface area with drain screens, it is clear why a Delia Toffola press design is on many levels the superior pressing technology.
