An existing plant retrofit: Krombacher brewery saves energy in spent grain handling with special SEEPEX SAI system.<br />
2<br />
The art of brewing with an energy-efficient twist<br />
Pilsner, wheat beer, cellar beer, Radler, dark or light beer: these beers from the West German brewery should not only taste good, but the hops<br />
and malt should also be used sustainably. To achieve this, the Krombacher brewery relies on SEEPEX’s high-tech pumps. When pumping spent<br />
grain, the Smart Air Injection (SAI) system from the Bottrop-based progressive cavity pump specialist uses significantly less compressed air<br />
than conventional methods. This saves up to 95% energy along with considerable costs.<br />
Smart Air Injection provides unparalleled performance when<br />
conveying abrasive and high viscosity spent grain.<br />
SEEPEX progressive cavity pumps have long been<br />
the internationally sought-after solution for conveying<br />
highly viscous media such as hops, trub and yeast.<br />
They also pump the by-products that occur during the<br />
brewing process. Almost every brewery can benefi t<br />
from SAI; the advanced pump technology from Bottrop<br />
optimizes the entire process.<br />
Significant energy savings when<br />
compared to pneumatic conveying<br />
systems<br />
When conveying spent grain, the extracted residue<br />
from barley malt, the SEEPEX SAI system has<br />
a signifi cantly lower energy consumption than<br />
conventional pneumatic systems.<br />
SEEPEX SAI system can be easily<br />
integrated into existing plants<br />
The Krombacher Bernhard Schadeberg GmbH & Co.<br />
KG brewery has been family-owned for generations.<br />
Today it is the largest private brewery in Germany<br />
and one of the most modern breweries in Europe.<br />
With an output of 5,756 million hectoliters of beer<br />
in 2022, Krombacher is one of the ten largest beer<br />
producers in Germany.<br />
“Together with the Krombacher brewery, we quickly<br />
and thoroughly worked out a specifi c solution tailored<br />
to the existing plant,” says Oliver Langen, SEEPEX<br />
Project Manager, “The goal was to increase energy<br />
effi ciency by transporting the spent grain as residual<br />
material in a cost-effective and sustainable manner.<br />
We are very satisfi ed, 95% energy is saved with the<br />
SAI system.”<br />
The pump specialists integrated the new, customized<br />
system into the plant using the existing compressed<br />
air system. A 5 m SEEPEX coupling rod replaced the<br />
screw conveyor. The pump elements were mounted on<br />
the existing hopper and the 30 m pipeline to convey<br />
spent grain at 15 m³/h.<br />
Goal: Moderate or eliminate use of<br />
compressed air<br />
“Our SAI system conveys the spent grain, after<br />
compressing it into huge plugs, into the silo by means<br />
of short pulses of pneumatically compressed air. This<br />
uses signifi cantly less energy than the compressed air<br />
systems in the industry to date, which operate with<br />
a continuous air supply,” says Tobias Blumenhofer,<br />
SEEPEX Product Manager, describing the optimization<br />
potential of the SAI system.<br />
The potential for reducing compressed air with SAI<br />
lies in discontinuous conveying. This is made possible<br />
by pneumatic dense phase conveying. SAI shoots<br />
the spent grain plugs through the pipeline with<br />
pulsed compressed air, similar to a pneumatic tube.<br />
Due to the short and targeted use of compressed<br />
air, up to 90% less compressed air is required than<br />
with conventional pneumatic wet spent grain<br />
conveyors. With similar energy costs in pump<br />
operation, SAI scores with massive savings in<br />
compressed air consumption. In addition, pipe wear<br />
is signifi cantly reduced – fl ow velocities through<br />
plug conveying are 5x lower than before.<br />
In large breweries, up to 150 tons of spent grain<br />
is produced daily, which corresponds to an energy<br />
consumption of up to 400 kWh of compressed air<br />
per brewing line. Until now, the material has been<br />
conveyed using conventional pneumatic wet spent grain<br />
conveyors with a continuous supply of compressed<br />
air. Krombacher had identifi ed considerable energy<br />
savings potential in this area during its investigations<br />
and found the right partner in SEEPEX.<br />
With SEEPEX’s extensive experience and unique<br />
SAI system, they were able to reliably meet the<br />
challenge of converting an existing plant over.<br />
