The solution for top economic results at big volumes:
Mechanical vapour recompressor heated evaporation de-alcoholisation of beer

Vapour recompressor


After regenerative prewarming, the beer is decarbonized in a thermal vapour recompressor heated falling film prewarmer. Following the beer is fed into a multipass fallfilm evaporator. There the degassed beer is evaporated economically by the mechanical recompressed water/alcohol vapours from the beer.

The vapours are condensing in the shell side of the evaporator and the condenser and the condensate is led to the wastewater system. All intert not condensable gasses are sucked out of the process by a liquid ring vaccum pump.

An optional aroma recovery is available to recover aroma components from the exhaust inert gasses. After regenerative cooling against cold infeed beer, the de-alcolized beer is blended to demand in a corosys carboblender.

Main benefits

Low temperature process

with short product residence time – low color or HMF or Furfural addition

Alcohol free beer

below 0.5 Vol% alcohol content

Additional aroma recovery

from non-condensable gasses optionally available

Heating by mechanical and thermal vapour

recompressor – optimum efficiency

Fit for fill:

additional corosys degassing system, corosys carboblend, corosys filtration and corosys flash pasteurizer blends the de-alcoholized beer with degassed water, beer, additions and CO2 to your final procuct and delivers it clear and pasteurized to the filler – seamless integration of processes!
