All breweries throughout the world are exposed to cut-throat competition which is becoming increasingly fierce. The need to operate efficiently is becoming more and more important in this respect. Beer recovery is very important in these conditions. More and more breweries are therefore investing in beer recovery – for a good reason. They are able to improve their efficiency whilst retaining the same beer quality. Indeed, the yeast and tank bottom volume accounts for around 4 percent of annual output, and of this figure approximately 60 percent is recoverable in the form of beer. At a brewery with an output of 1 million hector litres, this is equivalent to 24,000 hectorlitres. Many operations have already been able to improve their efficiency by using GEA Westfalia Separator beer recovery technology. Which of the three possible systems, namely separator, decanter and ceramic membrane filter, is used in this respect depends on the specific conditions of the brewery. GEA Westfalia Separator is the only provider to make all three process alternatives, and can make the recommendations which are suitable for every operation.
Most simple process with separators
The most simple process uses separators with minimum investment costs. With its continuous operation the process time is only 120 seconds, the yeast is accordingly subject to very gentle treatment. On the other hand, the production times are long: A standard CIP process is carried out on the separator only every 72 hours. With the separator GSC 250, GEA Westfalia Separator has now launched a new performance class of this machine series at the drinktec with up to 800 hl/h. The separator is suitable specifically for beer recovery, and achieves dry matter of around 25 percent in the yeast thanks to the Westfalia Separator® hydrostop discharge system. The hydro hermetic feed ensures gentle product treatment. In addition, the hydro hermetic arrangement prevents the product from coming into contact with the outside air, and operates with absolutely no wear-and-tear.
With the separator GSC 250, it is possible to recover beer from the yeast and also to clarify the young beer from the fermentation tank with the addition of yeast upstream of the separator.
