Food and Beverage
The NDCF - novoflow Dynamic Cross Flow Filtration system is the alternative to presses and conventional filters. It is used extensively in wine and juice filtration.
Concentration and Clarification
Versatile use throughout the entire period:
- Sediments from must clarification (sludge from de-sliming)
- Centrifuge discharge from must clarification
- Sediments after fermentation (yeast lees)
- Yeast from first and second self-clarification (fine lees)
- Fining treatment sediments
- Residues from cross-flow microfiltration (retentate)
- Sediments from tartar treatment
- Sediments from deacidification steps
Yield from lees: 60 - 70%
From fining: 70 - 80%
Integrated filtration of young wine is an option, as well as filtration in a fermentation process or as a replacement for existing clarification.

- Filter agent-free filter system replaces vacuum filters and filter presses for fruit juice, wine and beer lees, as well as for fruit juices and wines
- The filtrate produced can be bottled directly
- No loss of taste or color compared to traditional cross-flow filtration
- No red color reduction (Abs at 520 nm)
- Very high solids concentration in the retentate at up to 80% vol/vol
- No oxygen uptake (with a very limited nitrogen purge)
- Very high nominal flow rate (30 - 50 l/m²h with a 30% vol/vol product)
- Reduction of turbidity to well below 1NTU
- No auxiliary materials necessary, thus maintaining quality
- Use of ceramic discs, so no release of plasticizers and no change in taste
- Low shear forces ensure that the aroma is preserved
