It was important to the Baldauf project managers that no air ducts were required for air
distribution, as these would have resulted in time-consuming manual cleaning. As a result,
the most convenient of all solutions has been integrated: The recirculating air hygiene unit
can now be cleaned automatically.
With the help of the air-conditioning system for the creamery and the process rooms,
highly filtered and conditioned fresh air is blown into the ripening warehouse in order to
be able to maintain a desired overpressure in the warehouse together using a controlled
exhaust fan. In order to cope with the different storage capacities in the individual storage
cellars, smart automation technology with high-precision room sensors and several

Smart air-conditioning and
hygienic air technology for
creamery and process rooms
Compliance with hygiene requirements
and greater energy efficiency were the top
priorities when finding the system for ventilating
the creamery and process rooms,
which also include cold storage, the machine
room, the laboratory, the temporary
storage and the salt bath. Since the creamery
and the process rooms had different
requirements for room conditions, a ventilation
concept with several temperature
control zones and individual room control
with separate supply and exhaust air volume
flow controllers was selected for each
area. The ventilation system has a highly
efficient heat recovery system in the form
of a cross-flow heat exchanger. The primary
energy requirement can be significantly
reduced thanks to a sophisticated load
management system and energy-efficient
operating mode, in which the fans are controlled
according to demand. The reduction
is considerable: The power requirement
(shaft power) of fans and pumps
changes by a power of three relative to the
volume flow. This means that if the air volume
is reduced by 20 percent, the power
requirement can be reduced by 50 percent.
With the help of a load-dependent
volume flow control, the individual areas
are only supplied with low supply air volumes
during break times or at night when
production is at a standstill, as lower room
loads occur during this time.
Conclusion: a creamery
with air technology for future
generations
Georg Baldauf formulated a goal before
construction began: He wanted to present a
model for a creamery that "can still function
in exactly the same way in 100 years". This
goal was also implemented in Goßholz with
regard to the hygienic air technology, which
contributes to Baldauf's ability to supply
Germany, the land of cheese, with speciality
cheeses that are consistently high quality
produced under sustainable conditions.
