Centrifuge Separators for Milk Skimming

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.

In all areas of processing, there are applications for dairy separators such as warm and cold milk separation, whey separation, buttermilk separation, cream concentration and butter oil concentration and polishing.

Skimming separators with GEA hydrosoft feed system

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.

 

These GEA separators give you the following benefits

  • Maximum availability: high throughputs, high efficiency, high economy, a universal solution
  • Flexible integration: flexible processing, high product quality
  • Innovative product protection: gentle feed system, gentle product treatment
  • Intelligent equipment: easy operation, uniform solids discharge, optimum yield
  • Highest economy: low maintenance costs, low operating costs, low water consumption, low energy requirement
  • Absolute robustness: problem-free operation, service-friendly, long service life

Cold milk separation by GEA procool

The markets for cold milk separation are expanding dynamically; the same is true for the earnings potential of efficient dairies.

GEA procool

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 GEA Separator procool 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.
 

Minimum Energy Input, Maximum Product Quality

procool has been developed with the benefit of over 110 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:

  • Improvement of the bacteriological nature of the end product by cold treatment of the raw milk
  • Energy savings as there is no requirement for heat
  • Reduction in denaturing of proteins (WPNI ≥ 6mg N/g)
  • Production of specific products according to the customer‘s specifications
In addition to these benefits, the procool innovation sets new standards in terms of throughput capacity, separating efficiency, process reliability and effec­tiveness of cold milk separation.

Technical Features & Capacities

GEA offers separators with flat belt drive (types MSE, GEA ecocream and GEA easycreampro) and integrated direct drive (type MSI). Our self-cleaning separators are for applications that require continuous processing. Separation takes place in the disc stack; the solids are separated out in the solids holding space.
