As a neutral basic for so-called FAB (flavoured alcohol beverages), a de-colourized and purified water-alcohol mixture is used. The basic material is beer (fermented alcohol base). Undesirable compounds, such as residual sugar, salts and long-chain colour and aroma components are separated.
GEA Filtration offers a modular plant design for feed rates from 50 to 250 hl/h, plants for higher capacities are designed according to the individual customers' requirements.
Depending on the quality requirements an additional absorption polishing step can be offered.
The membrane filtration plant can easily be integrated into an existing brewery in order to add a FAB process line. The expenditure for equipment is low, the construction is compact using cost-efficient spiral modules and the process is reliable. At at the same time, operating costs are low thanks to energy efficient design and semi-automatic operation. All these features, together with the standardized modular plant design, result in an extremely cost-effective design of the membrane filtration plant.
The process can also be used for other alcoholic base products (e. g. wine, cider).
