Winegrowers Supplies  -  Filtration - to produce 'cloudy' juice or cider

Sheet filtration: a range from 0.2 to 20 microns, is too fine to produce a cloudy cider.

Cross-flow filtration: is too fine to produce a cloudy cider.

Centrifuge: the best way to achieve a natural cloudy juice or cider, which remains almost stable in the bottle, is with a centrifugal separator (a new machine costs about 45,000 Euros). You can regulate the level of filtration, down to 25 microns is possible.

Diatomaceous Earth filter: the alternative is to use a Kieselguhr filter, but it's not easy to keep the consistency, and there is no positive effect to keep the cloudiness stable when in the bottle.
