DeAlcoTec

The Centec dealcoholization system DeAlcoTec is a sophisticated and highly efficient system for the removal of alcohol from beers. Incoming alcohol rich product is first gently heated by a heat exchanger to promote evaporation. It is then injected into the top of a specially designed evaporation column. At the bottom of the column exhaust vapours are also injected. They rise upwards inside the column counter current to the falling warm liquid, thereby removing the volatile alcohol components from the beer. The less volatile components in the beer fall to the column base where some are heated to produce more exhaust vapours for reuse in the system. The remaining alcohol-free product is pumped away and cooled for storage or further processing as required, e.g. for carbonation. The volatile flavours from the original product can be separated from the exhaust vapours in a special aroma recovery system and added back to enhance the taste of the finished beverage. If required, the alcohol vapours are concentrated, chilled and condensed to form liquid alcohol of up to 90 vol.% for use in other applications or for sale to industry as a food grade product.
