Bucher Denwel De-Alconox M De-Alcoholisation System

Bucher Denwel’s state-of-the-art membrane based de-alcoholisation process takes place in three gentle, temperature-controlled steps:

Step 1 Concentration Phase: a mixture of water and alcohol is separated from the beverage, reducing the product volume by approximately 30–50%.

Step 2 Washing Phase: the remaining product is further purified and the alcohol content reduced by rinsing with de-aerated water.

Step 3 Re-dilution Phase: de-aerated water is added back to achieve the desired final alcohol content and product volume.

• Membrane separation technology – Alcohol + water mixture is separated from the beverage without heat damage to flavor compounds.
• Low operating temperature (< 10 °C) – Prevents formation of heat-related off-flavours and maintains product integrity.
• Closed system design – No oxygen ingress, protecting product quality and oxidation-sensitive components.
• High flexibility in ABV control – Final alcohol content can be adjusted precisely (≤ 0.5 %) to suit product targets.
• Low energy consumption – Economical operation means lower utility costs.
• Compact skid design – Minimal footprint, ideal for breweries with limited space.
• Modular capacity options – Available for daily batches from ~ 5 hl to 100 hl, accommodating small to medium producers.
• Gentle on aroma & taste – Membrane pore selection ensures retention of volatile aromatic compounds.
• Scalable production – Multiple skids can be operated in parallel or series for higher throughput.
