Au2mate standardising unit is applied for automatic high accuracy standardising of the fat % in the cream line and the milk line after a milk separator. The standardising unit can be applied in new as well as existing installations.
The standardising unit can operate as stand-alone or seamlessly integrated with a SCADA or factory control system. The unit is pretested and delivered ready to install in the dairy plant.
The working principal for the Au2mate standardising unit is basically to standardize the cream to the required cream fat % and blend back the cream into the milk line in an adequate quantity to achieve the required milk fat %. This functionality is achieved by means of two regulating valves installed in the cream line operating in a cascade regulating loop based upon measurement signals from two density transmitters installed in the skim milk line and in the standardized cream line and a flow transmitter installed in the cream line dosing back to the milk line. The density transmitter measurement is compensating for fluctuations in the product temperature as well as variations in the skim milk fat % from the separator.
