Skimming separators split the incoming whole milk into skim milk and cream. If milk with a defined fat content is to be produced instead of skim milk a certain part of the cream has to be dosed back into the skim milk. This procedure is called standardising. Besides the continuous control of the standardised milk fat content the Westfalia Separator^® standomat units can also provide a continuous control of the cream fat content and a proportional dosing of additives.

With all models the cream fat content is determined via density measurement in a mass flow meter. The cream fat control is effected by variation of the cream
flow. Control procedures adapted to the different operating conditions (start up, production, bowl discharge, shut down) take into account the specific requirements of the separator. For standardizing, a part of the cream flow is controlled via an inductive flow meter and dosed back into the skim milk. The control components for the skim milk back-pressure are integrated on the Westfalia Separator^® standomat base unit. For all milk applications a control signal is supplied for the feed flow to the separator.

Depending on the application and the control task you can choose amongst ten different Westfalia Separator^® standomat models:

• Westfalia Separator^® standomat WC fat control for whey cream
• Westfalia Separator^® standomat C fat control for cream
• Westfalia Separator^® standomat CB fat control for cream + complete
  back blending (whole milk)
• Westfalia Separator^® standomat MC fat control for cream + fat control for milk
• Westfalia Separator^® standomat MCL fat control for cream + low fat cream < 28% + fat control for milk
• Westfalia Separator^® standomat MCFD fat control for cream + fat in dry
  matter control for cheese milk
• Westfalia Separator^® standomat MCA fat control for cream + fat control for milk + additive dosing
• Westfalia Separator^® standomat MCFP fat content reulation cream + fat content regulation milk + protein content
• Westfalia Separator^® standomat MCLA fat content regulation cream (also < 28 %) + fat content regulation milk + additive dosing
• Westfalia Separator^® standomat CMC fat content regulation cream + fat content regulation milk 

The above-named versions describe only some of the possibilities available. As regards individual applications, GEA Westfalia Separator offers solutions customized to the needs of the customer.
