Centrifuge
Today’s separator installations, incorporating cleaning-in-place systems, can be operated 24 hours a day. All available GEA separators can be operated continuously and offer the highest level of product safety and efficiency and thus represent the state-of-the-art in centrifuge technology.
To this day, milk and whey skimming is the core task for dairy processing companies. Here, high expectations are placed on the centrifugal separator in terms of separation efficiency, flexibility, economy, cleanability and availability.
Our unparalleled selection of bowl formats, pioneering features and different product lines for different requirements ensure the optimum solution for each of your requirements. This includes not only the centrifuge itself, but also its precise integration into your production environment by our process specialists.
Cross cut hydrohermetic feed
The hydrosoft feed system combines the advantages of the GEA softstream system with those of the hydrohermetic feed system. Combining these systems allows very gentle acceleration of the product at a low pressure level. The system offers a high degree of flexibility in terms of feed capacity. Owing to the cream centripetal pump situated above the system, which is immersed in the cream during production, the inlet chamber is hydrohermetically sealed off from the outer air. Air intake into the product is therefore not possible. The stationary feed tube allows the product to flow into the centrally-located bore of the rotating distributor The central bore has no ribs so avoids shear effect on the product. The product is gently fed through the radially arranged bores into the inner rising channels of the disk stack where it is separated into skim milk and cream.
Optionally, the skimming separators can be equipped with the proplus system. With proplus it is possible to extend the ejection intervals during production up to six-fold compared to conventional skimming separators. The result is a significant boost in protein yield from the raw milk used by means of consistent loss minimization of up to 75 %. In addition, there is a decrease in costs for waste water, maintenance and wear.
The heart of a whey processing line is usually a skimming separator for the removal of fat from whey. These centrifuges can only process a limited amount of cheese fines and must be complemented by an upstream clarifying separator to maintain a good skimming performance.
When feed conditions vary regularly, the new GEA CleanSkimmer gets into the game, which is not only suitable for whey, but is also the first choice for milk with an increased non-milk solids content. This specially designed centrifuge is capable of satisfactory skimming efficiency even at increased cheese fines loads without the need of a clarifying separator upfront.
GEA’s new “workhorse” thus not only facilitates the processing of whey, but also the skimming of milk with a higher content of non-milk solids content.
For cheese manufacturers, processing residual whey is no longer an option but a mandatory task if they not only want to avoid high disposal costs but also strive to complete their portfolio with high-value products such as whey protein isolates.
And there are many good reasons for removing the remaining fat from the whey as completely as possible.
High fat recovery means
Especially when different types of whey need to be processed and when a higher cheese fines concentration may only be expected from time to time, the investment of a premium clarifier and skimmer combination might be difficult to justify.
In this case, the newly designed GEA CleanSkimmer is just the perfect match, delivering satisfactory skimming results while being tolerant against increased solids loads.
A special bowl design prevents solids with a concentration of up to 0.2 % vol. from clogging the centrifuge. The GEA CleanSkimmer can thus be operated at a reasonable discharge frequency while maintaining a stable skimming efficiency of up to 0.06 % fat in skim whey/milk.

Cold Milk Separator
Dairies, particularly in the USA, Mexico, Australia and New Zealand, are increasingly using cold milk separation for skimming purposes.
Separating milk in this way allows dairies to comply with their customers’ quality requirements for products such as milk powder and drinking milk. Cold milk separation with GEAprocool satisfies this requirement both in terms of the physical and microbiological properties of these products. procool also stands for a new and permanent optimum efficiency throughout the entire process of cold milk separation.procool has been developed with the benefit of over 125 years of experience in the milk processing industry and technology leadership in mechanical separation technology. procool fully develops the overall benefits of cold milk separation:

GEA proplus extends the ejection intervals of milk separators from 20 – 30 minutes to up to 90 minutes. This ensures added value, a significant increase in protein yields from the quantity of milk used and a clear reduction in fresh water consumption and waste water creation.
Even the best centrifuges cannot function optimally if they are not partnered with control systems of equal quality. For their range of separators and decanters, GEA offers standardized as well as tailor-made solutions for machine automation with many features to meet customer requirements.
