Aurora Kaas – Kranenburg
Complete line for preparation and concentration of whey
Cheesemaker Aurora Kaas, the
family company Ten Dam with a
long tradition in cheese production
in the Netherlands, has built
a new modern cheese dairy for
organic cheese made from cow, goat and
sheep's milk as well as for regional cheese
varieties in Kranenburg, Germany, in 2019.
The milk for the cheese production comes
exclusively from organic farms.
Italian company REDA was commissioned
to build the whey utliisation and
concentration line in the cheese dairy.
REDA has specialised in the construction of
milk separators, aseptic UHT plants, membrane
filtration technology and evaporation
plants for the dairy industry. The whey
concentrate is sold by Aurora Kaas to Colmena
in Belgium, with Colmena participating
in the investment in Kranenburg.
Whey line
The whey line is designed for a continuous
operation of 200,000 litres of whey per day.
The REDA whey line consists of the following
equipment:
• reception plant for whey from outside
• tank farm for fat whey from the cheese dairy
• pasteurisation plant
• separator for whey cleaning
• separator for whey skimming
• separator for bacteria removal from milk
• membrane filtration plant and polisher
• storage tanks for finished whey, permeate
and whey concentrate
• shipping station for whey concentrate
Fat whey, reception
and storage
The fat whey from the cheese dairy comes
cold (approx. 10°C) through a vibrating
sieve into two storage tanks for fat whey.
For this purpose, a Bardiani automatic
valve manifold with CSF pumps was installed.
Bardiani valves and CSF pumps
belong to the CSF group from Parma.
Furthermore, it is possible to receive liquid
whey from other cheese dairies via a fully
automatic REDA whey reception system with
a capacity of 40,000 l/h and, if required, to
treat it either in the REDA plant (cleaning –
skimming and pasteurisation) or to concentrate
it directly in the membrane plant.
Whey cleaning, skimming,
pasteurisation
The stored fat whey is then cleaned, skimmed
and pasteurised in the REDA pasteurisation
plant in the process room. This line has a capacity
of 12,000 l/h. The pre-treatment is important
to ensure the quality of the concentrated
whey and a long life of the membranes.
The REDA separators stand for robustness,
low-maintenance and long term use.
They guarantee a gentle product treatment
and optimal separation efficiency. They are
self-desludging, all models are equipped
with a frequency converter in the control
unit for power-saving control of the motor.
The pasteuriser was supplied pre-assembled
and has high-quality, state-of-theart
equipment with plate heat exchangers
with high heat recovery and measurement
and control technology from leading manufacturers,
which all in all guarantee reliable
whey treatment before concentration. Finally,
the skimmed, cleaned and pasteurised
whey is sent to the REDA membrane plant
for concentration.
