GEA standomat standardization unit for cream fat or milk fat
The GEA standomat MC plus is equipped with extreme precision controls to allow you to get more cream out of your milk standardization process.
Control system
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.
How does it work?
For standardizing, a part of the cream flow is controlled via a mass-flow meter and dosed back into the skim milk. The control components for the skim milk backpressure are integrated on the GEA standomat base unit. For all milk applications the feed flow to the separator is fully controlled and monitored.
What is standardizing?
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 standardizing. Besides the control of the cream or milk fat content, the units can also provide a proportional dosing of additives. Skimming separators split the incoming whole milk into skim milk and cream.

fat content regulation cream + fat content regulation milk
The above-named versions describe only some of the possibilities available. For individual applications, GEA offers solutions customized to the needs of the customer.
GEA standomat WC
This model is specially designed for the control of whey cream. The cross sections are adapted to the very small cream flow in whey skimming. A partial recirculation of the cream to the feed flow reduces the response time and enables a quick reaction on varying feed flow rates and fluctuating raw whey fat contents.
GEA standomat C
Provides a precise control of the cream fat content at varying feed flow rates. The production is limited to cream and skim milk.
GEA standomat MC
Designed for cream fat control and standardization. It produces cream, skim milk, standardized milk and whole milk.
GEA standomat MC plus
Developped for cream fat control and standardization. It produces cream, skim milk, standardized milk and whole milk at an outstanding level of accuracy. In combination with the latest generation of GEA IO, which ensures a safe and reliable operation to maximize the centrifuge's performance and availability, an improved calibration makes the process of standardization much more precise and tolerance insensitive.
GEA standomat MCL
In addition to the features of the GEA standomat MC this model allows the production of low fat cream < 28 %, e. g. 10 % coffee cream. This unit enables the production of cream, low fat cream, skim milk, standardized milk and whole milk.
GEA standomat MCA
In addition to the GEA standomat MC the dosing of one additional liquid component like cream, protein concentrate, lactose concentrate or vitamin solution is included. This allows the production of cream, enriched skim milk, enriched standardized milk and enriched whole milk.
GEA standomat MCLA
This version is based on the MCL model. Additionally, dosing in the corresponding ratio and complete admixing of additional components can be realized.
GEA standomat CMC
In the cold milk process, this model additionally regulates the fat content of the milk (standardization). By this means, cream, skim milk, standardized milk and whole milk can be produced.

Standardization process
Milk standardization process
Procedure with warm milk
A high performance of the control system requires a stationary operation of the system at steady process conditions. The system is calibrated according to laboratory tests, which can be done by different analytical methods. Thus, any verification has to be carried out using the same methods. The accuracy of these different methods has to be taken into consideration while interpreting results.
The maximum fat content for standardizing is 0.2 % below the incoming whole milk fat content. The deviation from the setpoint for cream fat control is +/- 0.2 %. For milk standardizing, this deviation is on-line 0.05 % right after the control unit and 0.025 % after a buffer tank.
Procedure with cold milk
Cold milk standardization in particular makes possible a fat content in the milk of 0.5 – 4.2 %, whereby the raw milk content should be at least 0.2 % above the standardized milk fat content. The standard deviation is around +/- 0.04 %. The cream can be standardized up to maximum 40 % fat content. The control deviation here is +/- 0.4 %.
Partial homogenizing
The models MC, MCL and MCA can be prepared for partial homogenizing of the standardized or whole milk. With this a good homogenizing effect can be achieved with a homogenizer of 1/3 of the total capacity.
Cleaning
The automatic cleaning of theGEA standomatis effected by the CIP of the separator. Optionally the connecting valves for a separate CIP of the surplus cream line can be integrated into the unit. The additive dosing line of thestandomatMCA is cleaned in a separate cycle in any case.
Compact unit
The models WC and C do not require a rack, the individual components have to be mounted on site into the separator connection lines. The models MC, MCL and MCA are preassembled as a compact unit in a stainless steel rack. The control cabinet and the solenoid box are mounted on the rack. All internal electrical and pneumatic connections are installed. Each unit is tested before dispatch.
Controls
GEAIOis the new control panel generation for all GEA separator and decanter applications, focusing on intuitive handling, efficient processes and reliable operation.
Control functions
Logical navigation without redundant information enables user-friendly operation and safe monitoring of all centrifuge functions. GEAIOcan be operated as an individual controller or via optional bus communication.
