Clarity, stability and quality prevail in the wine business. Conventional methods of filtration, like pad filtration or diatomaceous earth (DE) filtration have disadvantages which are high wastage, labor-intensive and can change the flavor. A better alternative is the use of cross-flow filtration (also with hollow fiber membranes or ceramics) as it is less vulnerable to fouling. The following explains the reason why; this technology is gaining popularity among winemakers.
The Highest Clarity, Stability and Flavor All in one
Cross flow filtration is able to efficiently filter out yeast, bacteria and colloidal haze without taking the aroma, color or tannin structure away with it. Unlike DE filtration where flavors may be removed, CFF is low temperature and low pressure, thus it conserves the natural qualities of the wine.
Minimized Garbage and Less Environmental Effects
Does not require Diatomaceous Earth repairing or hazardous waste disposal required. Usage of landfills is decreased.
Water and Energy Saving - Cross flow systems re-use the water, reducing the amount used in a clean-up.
Low Product Losses Low product losses are generated in the degree compared to the no-return filtration because 98 percent of the wine is recovered.
Increased Filter Length Life and Reduced Operational Costs
Self-cleaning Mechanism- The membrane is scrubbed in the continuous tangential flow and clogging does not occur.
Reduced Numbers of Filter Changes- Ceramic and hollow fiber have a long-life of years with good care.
Labor Cost Reduction Through automation, less work-force is needed as compared to traditional counterparts.
Flexibility for Different Wine Types
Cross-flow filtration fits any style of wine:
White and Ros Wines- Gives a brilliant clarity without removing the delicate aromas.
Red Wines -Eliminates tannins and microbial spoilage and destroys body.
Sparkling Wines- Makes wine microbially stable prior to secondary fermentation.
Rapid Processing and Increased Efficiency
Single-Step Filtration - (Instead of several clarification stages: fining clarification, centrifugation, DE clarification).
Constant Processing - CFF can only process wine without any interruption as compared to the batch processing.
Conclusion
The use of cross-flow filtration in wine production is transforming the industry by way of improving the quality, reducing expenses and making it sustainable. The improvements in quality, reduced waste, flavor preservation, and monetary savings in the long term are all only some of the reasons why the most prestigious wineries are making the switch to this fruit juice concentrator system.
