Brewery in Midwest - This Brew's For You
Did you know that Hoffer turbine flowmeters are used in the
brewing process by an Internationally recognized company with
a significant share of the beer market? While the actual ingredients
used in the brewing process have not changed significantly
over the years, automation of the process and stateof- the-art
control capability have provided for exacting standards that
provide for superb product quality control.

A critical part of the brewing process occurs after
"mash" has been created. This mash, consisting
of water and grain, is transferred to a settling tank
referred to as a Lauter Tun. The Lauter Tun, a large
diameter flat bottom vessel, is used to separate the
wort, the sugar solution, from the grain. Inside this
Lauter Tun is a rake which is used to stir and level
the grain as it settles to the bottom of the vessel.
The rake is operated hydraulically using filtered pure
water. The Hoffer turbine flowmeter is used to monitor
the filtered pure water flow. The use of the filtered
pure water is for sanitary reasons, which assures that
if a leak were to occur in the rakes hydraulic system,
the only thing that could make contact with the wort
would be the pure water.
Once this separation is completed, the wort is pumped
out of the vessel for fermentation. Cleaning water is
added to the separator vessel and the rake once again
stirs the grain as the water and used grain are pumped
out. The cleaned vessel is then ready for the next batch.
The specifying engineer at the brewery selected the
1" Hoffer turbine flowmeter for use on the pure
water hydraulic flow application. Hoffer was specified
due to the need for high accuracy and repeatability
over a wide flow range. The repeatability and accuracy
at the low flow rates are particularly critical because
the flow is alarmed for low flow conditions. This allows
the customer to check for a leak in the system or a
possible malfunction should an alarm occur.
Another important feature of the Hoffer turbine flowmeter
is the all stainless steel construction to maintain
the high purity level of the water. All lines in the
hydraulic system are also stainless steel. Multiple
1" Hoffer flow systems have been installed in this
large midwestern brewery for this critical application.
After straining is completed, the brewing process continues
on to kettle brewing, cooling, fermentation and finishing.
Beer is "big business" and to give you an
idea to what extent, check this out. 16 million 12 ounce
beers are produced on an average day by this large midwestern
brewery. That's a lot of brewskies! |
