EMBRACE CHALLENGES WITH INNOVATIVE SEPARATION TECHNOLOGY Global competition and changing consumer demands pose new challenges for the industry. This makes it all the more important to rely on innovative and flexible solutions to meet the challenges of tomorrow. Changing environmental conditions are affecting crop yields and the quality of grapes. Modern processes in must treatment and winemaking are therefore essential to ensure the best possible quality. Flexible, reliable, and easy-to-operate plant technology such as decanter centrifuges and clarifiers play a key role here. They make the efficient...

How to turn a good harvest into an even better product Both must preclarification and lees management are crucial process steps in the processing and refining of grape must. Flottweg separation technology excels in this area thanks to its optimum yield, its robust design, and comparatively low operating costs. Advantages of the Flottweg decanter centrifuge for must preclarification ∙ ∙ ∙ ∙ ∙ Quick processing of must and must residues, even in case of a high solids content Closed discharge of the clarified must reduces oxygen uptake/oxidation Hygienic design and CIP capability for efficient cleaning,...

One such example is for the preclarification of must. The special construction of the Flottweg decanter doesn’t only offer economic benefits, but also quality advantages when it comes to the processing of must. The machine separates lees from the must within a few seconds, thus...

FINE FINE CLARIFICATION CLARIFICATION ... with the Flottweg separator Enhanced quality Clarifying processes don’t play an important role in the processing of must. Efficient clarification may have a significant impact on the taste of the wine during the entire wine production process and thus on its market value. Separator-based preclarification helps remove the finest lees, which could adversely affect the taste of the wine during further production stages. Moreover, further fermentation is more consistent and can be better controlled. The wine maturation is optimized. In wineries, some fine...
