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.

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.
