De-alcoholization Module

Alfa Laval’s fully automated de-alcoholization module removes alcohol from beer using single-pass stripping at low temperature and pressure, with flow rates up to 100 hl/h.

Single-pass stripping

Fully automated, energy-efficient solution for removing or reducing alcohol in beer to produce full-flavoured low and no-alcohol beers.
Single-pass stripping at low temperatures and short residence times supports high-quality, high-flavour dealcoholized products.
Prefabricated, modular plug-in design makes installation and integration easy, adding non-alcoholic brewing capability without major capital investment.
Low running and maintenance costs, with no rotating parts in the stripping column.
Configurable to recover aroma from the feed beer and dose it back into the product to maintain flavour.
Effective alcohol removal without recirculation to achieve the required final beer specifications; a recirculation loop is included if additional stripping is required.

Specification	Value
Standard capacities	10, 50 and 100 hl h
High flow rates	up to 100 hl/h for 0.0% and <0.5% beers

Beer is first degassed, with condensable volatiles returned to the beer stream.
Alcohol is removed in a vertical stripping column under conditions close to a vacuum. Culinary steam flows upwards through densely packed material proprietary to Alfa Laval, maximising the effective contact area between beer and stripping gas for high desorption.
Production capacity is set by regulating incoming beer flow. A liquid distributor at the top of the column disperses beer, which trickles downwards against the rising stripping gas injected at the base.
Stripped vapour containing steam, alcohol and other volatiles exits the top of the column. A plate heat exchanger cools it into an alcohol condensate stream.
A final vacuum phase removes remaining non-condensable volatiles. A glycol-side recirculation pump minimises the risk of the stripped vapour stream freezing during condensation.
Stripping efficiency can be increased by regulating beer temperature before it enters the column or by altering system pressure.
