GEA’s water-saving membrane system for non-alcoholic beer

GEA AromaPlus PRO reduces the water consumption for diafiltration during dealcoholization by as much as 100 percent. The alcoholic base produced as a by-product of the filtration course of can be used for manufacturing other drinks in the brewery, similar to hard seltzer.
GEA AromaPlus uses a filtration know-how with special polymer membranes to separate alcohol and water from the other components via reverse osmosis; these ingredients are essential for the aroma, colour and turbidity of the final product. Adding the new PRO expertise to the water-saving CO2 blow-out function and the selective membrane which is already applied within the AromaPlus unit design, GEA saves greater than two thirds and as a lot as 100% of the fresh water used for diafiltration.
“Our newest AromaPlus technology combines the pattern in the path of zero.0% beer with the objective of reducing water in production,” says Ralf Scheibner, filtration skilled at GEA, underneath whose management the GEA AromaPlus has been further developed. “In reality, a membrane process requires plenty of water to flush out the alcohol. เกจวัดแรงดันco2 is a matter for breweries with a limited deoxygenized water availability. Our new PRO answer is a crucial step for them towards contemporary water neutrality in production processes.”
The complete dealcoholization system GEA AromaPlus is mounted on a body. It comprises the filtration modules and reverse osmosis membranes, pumps for media switch and system stress build-up, the complete internal piping, a CIP dosing unit put in next to the system, and the control equipment required for semi-automated operation. – Image: GEA/Mike Henning.
While breweries need much less fresh water for the diafiltration step, the permeate leaving the system may be reused as a useful by-product. Due to its decrease quantity, it has the next alcohol content material and may therefore function a base for alcoholic mixed drinks and newer beverages, similar to onerous seltzer, or could be reused inside the brewery itself.
“The Corona pandemic showed that breweries whose production services offered the flexibility to process other drinks coped finest with the drop in demand. GEA AromaPlus is an efficient example of how prospects can gear their plants towards high demand dynamics,” says Scheibner. Originally designed for the dealcoholization of beer right down to 0.0%, the system may additionally be used used for different non-alcoholic beverages, similar to zero.0% cider.
