Dealcoholization System DAS

The DAS: Dealcoholization and production solutioncorosys SMCOur state-of-the-art de-alcoholization system, DAS, offers you the opportunity to de-alcoholize a wide range of alcoholic beverages, including top-fermented and bottom-fermented beer, wine, sparkling wine, and more, to an impressively low residual alcohol content of under 0.04% Vol. This remarkable effect is achieved by applying a low-temperature, vacuum-based process, ensuring an extremely gentle treatment of the product with no compromise on quality.

What truly sets our system apart is the seamless integration of various dosing and carbonation options, allowing you to obtain not only a de-alcoholized base but also a ready-to-fill product in a single production step. This translates to a significant increase in your production efficiency and output.

Furthermore, our system offers the additional benefit of ethanol recovery. The removed ethanol boasts an exceptionally high concentration of over 70% Vol and can be even higher upon request. This not only contributes to resource efficiency but also enables you to reuse the recovered ethanol, resulting in substantial cost savings. In summary, our DAS de-alcoholization system offers a comprehensive solution for your production needs, harmonizing quality, efficiency, and sustainability.


How does the DAS work?Our de-alcoholization system employs an innovative process to remove alcohol from carbonated products, producing high-quality alcohol-free beverages. The process begins with degassing the carbonated products in a specialized step to remove excess gases. Subsequently, the actual de-alcoholization takes place in a rectification column operating in counterflow to the rising vapors. The majority of alcohol is transferred from the trickling product into the vapor phase. This step is carried out extremely gently and efficiently, as it is performed at low temperatures under vacuum conditions.Funktionsweise Entalkoholisierungsanlage DAS

To preserve the taste and aroma of the product, we employ advanced aroma recovery technology. This process allows the extraction of aroma components from the gas phase, which are then selectively reintroduced into the product. This contributes to maintaining the quality of the de-alcoholized beverage at the highest level.

The de-alcoholized product, extracted from the falling film evaporator, is then cooled by the incoming product still to be de-alcoholized. In a subsequent step, it is blended with various components such as mother beer, water, recovered aroma, wort, or base material. Finally, the product is carbonated and subjected to short-term heating if required. The result is the complete production of alcohol-free beers and mixed beverages, all within a single, highly efficient system.

Therefore, our de-alcoholization system offers a comprehensive solution that not only enables alcohol removal but also preserves the taste and aroma of your product, while ensuring efficiency and quality.
