Compact Milk Pasteurizer Units from GEA Westfalia Separator
Liquids to Value
The pasteurization line is the heart of every dairy.
It ensures the necessary heating process according
to the legal regulations and the technological
requirements respectively.
Besides the heat exchanger, a main component of the
pasteurizer is the skimming separator which splits the
milk into cream and skim milk and eliminates at the
same time non-milk particles.
So, our range of well-proven milk separators together
with our important process engineering expertise
is a perfect basis for designing high standard milk
pasteurizer units.
Our pasteurizers are used to produce a wide range
of dairy products such as liquid milk (whole/
standardized/skim), Rjashenka (high heated milk),
cheese milk, yogurt milk, kefir milk, fresh cheese milk,
whipping cream, coffee cream, cream for smetana,
crme fraiche, butter making cream and others.

GEA Westfalia Separator
At a temperature of approx. 131F the milk is fed into
the separator where it is separated into skim milk and
cream. The cream concentration is adjustable from
28% to 45% percent.
In the separator, the milk is cleaned from non-
milk particles by centrifugal force. The Westfalia
Separator ecoplus separators, MSE 25-01-177,
MSE 55-01-177, MSE 75-01-177 and MSE 85-01-177,
from GEA Westfalia Separator, are self-cleaning
and feature automatic periodic discharge of the
separated solids.
Cream is delivered at approx. 131F to a cooler or to
intermediate storage. Prior to further use, the cream
has to be pasteurized separately.
After this, the skim milk is heated further up to
165F and maintained at this temperature for 15 s
in a holding tube. The pasteurizing temperature
is continuously monitored and recorded. An
automatic change over valve at the end of the
holding tube returns insufficiently pasteurized milk
to the balance tank in case the temperature falls below
the limit.
The basic design of the milk pasteurizer unit provides a short term heating process with integrated milk cleaning and skimming. Cold raw milk arriving from a storage tank is led into a balance tank and pumped into the first heating section.

Subsequently the milk is fed to the regenerative
cooling sections to heat the incoming raw milk. The
recovery of 92 percent of the thermal energy reduces
the energy demand of the unit to a minimum. Finally
the milk is cooled down to a storage temperature of
39F 46F by ice water.

1. Bacteria ClarifierTo reduce heat resistant spores, which
can be present in the pasteurized milk, a
bacteria clarifier can be integrated. This is
recommended for the production of low
nitrate cheese.
2. StandardizingFrequently, instead of full skimming, the adjustment
of a defined fat content below the raw milk fat
content is required. This is achieved by a partial
return of cream into the skim milk. Optionally,
manual standardizing equipment or the well-proven
fully automatic Westfalia Separator standomat
are available.
3. DeaeratorIn some cases a deaerator is required to deodorize
the milk.
4. HomogenizerA high pressure homogenizer provides a size
reduction and an even distribution of fat globules as
well as added powder particles in order to prevent
sedi mentation or creaming during storage.
5. High HeatingDepending on the customers production philosophy,
the bacteriological status of the pasteurized milk
can be improved by increasing the pasteurization
temperature. This is one of several measures to
increase the shelf-life of the final product.

6. Extended Holding TimeAn additional effect of the same kind is obtained
by extending the holding time. Also, some products
require this strong heating to achieve a modification
of the chemical structures of the milk. Mostly this is
used for the processing of yogurt milk.
7. Differential Pressure ControlThis is a safety feature against a possible
contamination of pasteurized milk by
unpasteurized milk in case of a plate crack in the
heat exchanger. It can be ensured by maintaining
a higher pressure on the pasteurized milk side using
a booster pump and a constant pressure valve.

8. Post-HeatingIf the pasteurized milk is further processed by
fermentation, an increased outlet temperature of 81F
104F may be required. In this case, the ice water
cooling section may alternatively be used for cooling or
for heating. This option is suggested for the production
of cheese, yogurt, kefir or fresh cheese.
9. Automation LevelThe semi-automatic control included in the basic
version can be upgraded to fully automatic control.
In an automatic environment a signal exchange via
digital I / Os or via Profibus is possible.
10. Cream CoolerCream is discharged from the separator at
approximately 131F. For long storage it should be
cooled down to 46F 54F.
11. Cream PasteurizerThe cream discharged from the separator is not
pasteurized and has to be considered as raw cream.
Depending on further processing it has to be
pasteurized which is done usually at 203F for 15s. The
cream pasteurizer can be placed on one skid together
with the milk pasteurizer.
12. CIP PlantIf no suitable CIP plant is available at the customers
installation this can be supplied together with the
pasteurizer with a common control system.
