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.
1. 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.
2. The equipment features a high degree of automation, is user-friendly, and incorporates overload protection during operation, making it safe and reliable. Consequently, it requires no constant monitoring or manual operation.
3. Membrane separation relies on fixed pore sizes and purely physical retention. Therefore, the quality of the filtrate is unaffected by filter media or operator skill, ensuring consistent output. This also simplifies quality control of the final product.
4. Compared to diatomaceous earth filters or plate-and-frame filters, this system eliminates the need for dedicated filtration personnel. Furthermore, as the membrane is non-adsorptive, its wear and tear are virtually negligible.
5. 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.
6. Rapid Processing and Increased Efficiency
Single-Step Filtration - (Instead of several clarification stages: fining clarification, centrifugation, DE clarification).
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.
