Alfa Laval De-alcoholization module
Cost-efficient solution for chilled non-alcohol beer below 0.05%
Introduction
The Alfa Laval De-alcoholization module enables breweries to
produce non-alcohol or very low alcohol beer without facing
the heavy capital investments typically required for such
applications. The cost- and energy-efficient de-alcoholization
concept provides chilled low-alcohol beer below 0.05%
alcohol by volume. This is achieved by a combination of
diverse technologies, from beer degassing and culinary steam
generation to vacuum stripping and alcohol condensing,
which work in tandem as an integrated system.
The system also produces a condensate stream composed of
water, stripped alcohol and other volatiles that can be reused
for ethanol production and concentration of aroma volatiles.
Application
The De-alcoholization module is ideal for removal of alcohol
from full-strength beer for the production of low-alcohol (LAB)
and non-alcohol (NAB) beer.
Benefits
• Single-pass removal of alcohol (to <0.05% ABV) with
degassing step
• Minimal thermal impact (stripping at low temperature)
• Low energy consumption
• Sanitary design prepared for CIP and SIP
• Exceptional reliability and low maintenance.
Design
The De-alcoholization module combines processes for
effective single-pass removal of alcohol from beer at low
temperature and pressure. The de-alcoholization principle
uses stripping without the need for recirculation. The process
is especially designed with focus on a high degree of energy
recovery, minimizing thermal energy and the risk of freezing
the de-alcoholized beer.
Options
• Pre-treatment with separator
• Final product carbonation and blending
• Seal water recirculation.
Working principle
Alcohol removal and condensate cooling: The alcohol
present in the feed beer is removed in a special vertical
stripping column. This column makes it possible to achieve
high desorption by flowing a stripping gas (culinary steam) up
a tower of densely packed material under conditions that are
close to a vacuum.
The production capacity is set by regulating the incoming beer
flow prior to routing to the liquid distributor at the top of the
column. This distributor then disperses beer into the column,
where it trickles downwards against the flow of the stripping
gas injected at the base of the column and rising up through
it.
The vapour stripped out of the beer consists of steam, alcohol
and other volatiles. This vapour vents from the top of the
column and a plate heat exchanger is then used to cool the
