DeAlcoTec
Gentle technology for best results
Our dealcoholization system works in such a way that aroma, taste, and quality are preserved while efficiently removing alcohol. Learn about the individual process steps and benefits.
-
Preheating & Regenerative Plate Heat Exchanger
The incoming alcoholic product is gently preheated in counter-current flow to the finished non-alcoholic product. -
Degassing of CO₂-containing beverages
Preliminary process to prevent foaming. -
Evaporation column & falling film evaporator
The product flows down from the top, while alcohol-diluted vapors rise from the bottom – an interaction under vacuum to remove the alcohol. The less volatile components remain. -
Aroma recovery
Volatile aromas that escape with the vapors are separated and returned to the product. -
Optional: Alcohol rectification & use
The alcohol can be concentrated to up to ~90% by volume (e.g. for other applications).
