Filtration Solutions for Wine Polishing

What is the purpose of a wine polishing filter? Clarifying agents, crystals, colloids, and microbes may still be present after initial clarification, stability, and maturation. Filtration for wine refinement aims to remove these contaminants in order to produce brighter wines with better filterability. This enhancement will assure the effectiveness of the final filtration stage, which involves the prompt elimination of undesired microbiological contamination prior to bottling.

Polishing may not be necessary before final filtration during bottling if the wine has recently been clarified with a cross-flow filter or other clarification filter. However, if the period between clarifying and bottling is too lengthy, the wine's filterability may be compromised, necessitating fine filtration to complete the final filtration properly.

Wine Polishing Filtration

Some wines may be polished in larger wineries before being delivered in bulk to off-site bottling locations or foreign exports. Customers can get filtering solutions for wine polishing from Alfa Chemistry.

Improve the Efficiency of Final Filtration

In the winemaking industry, sheet-based filtration solutions are often used for polishing filtration. These products are made up of cellulose, diatomaceous earth, and perlite, and offer the ideal blend of adsorption, surface, and depth filtration.

The following are the characteristics of a good polished filter:

  • Removal of undesirable colloids closely related to membrane fouling
  • Microbial reduction to reduce the load of pre-filter and final filter during bottling
  • Maintain sensory properties
  • high yield
  • High Flow

A flat panel has traditionally been the favored format for this medium. Many vineyards still utilize filter presses for this purpose. Flat filter plates have some drawbacks, notwithstanding their effectiveness. This could put the wine in danger of being contaminated by the environment. Installation and assembly are labor-intensive due to the parallel assembly of several elements. Edge leakage is common due to the seal's reliance on operator and equipment maintenance, resulting in product loss and unsanitary conditions.

Alfa Chemistry addresses these flaws by utilizing a proprietary method in a confined environment to improve the performance of polished wine.

Learn About Our Products and Technologies

The Alfa Chemistry deep filtration module is the most recent advancement in sheet filtration technology, designed to give brewers with a cost-effective and high-production option. One module housing may replace up to 150 sheets of 60 cm × 60 cm sheets, making it ideal for large-scale wine production. Alfa Chemistry's ll depth filtration modules have unique cleaning and backwashing capabilities, making them ideal for small and medium-sized wineries.

The two technologies mentioned above are now available for our new zero DE (ZD) format as well. Users can eliminate diatomaceous earth from their processes using ZD media. To address client needs and expectations for higher performance products, the modules provide increased capacity, dependability, processing benefits, and resilience.
