has installed the module CIP Flex. This
means that it is possible to individually
parameterize cleaning processes without
IT specialists or service technicians in order
to be able to set up a CIP sequence
suitable for process requirements. All
possible evaluations can be called up at
the touch of a button, they can be visualized
on masks pre-installed or customized.
This not only provides all documentation
required for certifications, but also approaches
for optimizing process flows.
In order to be more flexible in the filling
of ESL milk and, above all, to ensure
its ability to deliver, the Hohenloher
dairy has installed a new Tetra Pak filling
line for 1-l edge packs with one-stop
opening (7,000 units/h).
Energy Optimization
On the energy side, a further optimization
with the installation of an ice water silo
from Tankki took place in 2016 at Hohenloher
Molkerei. This was supplied by the Haas
company. It holds 191 m³ of ice water, which
is formed via NH3 over a pipeline of 1.104 m
length in the silo. The storage capacity is
almost 7,000 MWh at 40 mm ice thickness.
The cold store is completed by an NH3 refrigeration
system, which was also supplied
by Haas. With its new and existing ice water
silo, Hohenloher Molkerei has sufficient capacity
to be able to shift the refrigeration
production to night-time operation. Even
when the unit is running at full load, the
refrigeration system can run for six hours
without regeneration, or it can intercept
peak power. Besides, a new cooling room for
fresh produce was built by Stadler.
Logistics
Last year, the Hohenloher Molkerei expanded
its storage area by approx. 3,000 m²
with the renovation of a neighbouring
building and an unused production hall
(85 x 35 m), which means that there are storage
facilities for another 10,000 pallets. The
connection to the production is provided
by forklift trucks, while another warehouse
is equipped with conveyor systems from
SEMA. SEMA has also installed a new palletizing
and pallet security center. With the new
storage capacities, the Hohenloher dairy
will build on the future. If on normal days
45 trucks are loaded with finished goods,
there were 70 trains on Foundation Day 2016.
Further growth in production can now be handled
without problems on the storage side.

New refrigeration center for the Hohenloher dairy
The Hohenloher dairy has further upgraded its refrigeration supply. One tank of Tankki
was installed. The cooling capacity in pre-cooling mode is approx. 2,300 kW. The storage
capacity of the two Tankki ice storage silos is approximately 11,500 kWh.

Tetra Pak PlantMaster
Tetra Pak PlantMaster is, according to the supplier, the only automation solution available on the
market that is based on comprehensive know-how in the field of food processing; it covers the
entire food production plant – from raw material acceptance to finished products, independent
of the plant manufacturer and can integrate several production sites.
Comprehensive control over the processes maximizes the value added by:
• a flexible, scalable and tailor-made plant automation and information solution, which maps
everything from a single plant part through a complete line to the entire production plant
• an open MES software solution that seamlessly integrates any plant or data source and stores
data in understandable information, for example, in reports or dashboards
• an overarching data management system, modular and retrofitable, which simplifies the manufacturer
independent integration of process systems with the ERP system and other data sources.
The solution is tailor-made for every company – with unlimited possibilities to supplement
new functions for future requirements.
