Clarified Raw Milk

Despite all the preventive hygiene measures, the raw milk delivered to dairies by agricultural businesses still contains unwanted foreign substances – such as somatic cells and blood from the udders, contaminants from the air and dirt from contact with the milking machines, the milk lines and the transport vehicles.

Milk should be clarified by separators to improve milk quality – for good reason: As a basic food, milk is subject to national and international laws. The aim of these laws is to ensure that milk and dairy products are brought into circulation only in perfect condition which will not harm health.

 Clarifiers from GEA Westfalia Separator are equally suitable for cleaning cold and warm milk. Compared to milk filters which are used as an alternative, self-cleaning separators are clearly superior, as in filtration the filtrate cake remains in the milk flow for several hours. A growing bacterial flora can thus reinfect the milk flowing through the filter. Furthermore, cracking in the filter cloth is virtually impossible to check. Even the smallest cracks can cause severe problems and risk-free operation of relatively large banks of filters requires a high degree of automation.

Compared to this, the clarifier is simple to integrate. Clarifier sludge can be routed straight to neutralization or to the waste water treatment plant which is present in any case. Last but not least, almost no product is lost as a result of treatment with clarifiers. The removal of milk sludge reduces valuable constituents of milk, such as protein, by only a barely measurable thousandth of a percentage point.
