Process management system for online measurement and automatic control of butter moisture content for continuous butter churns. Today, it is no longer sufficient to effect laboratory examinations. Utilizing a metering system that collects and adjusts all important process data during production has become necessary. All parameters and data essential for the process, e.g., the moisture content, the butter temperature or the amount of cream, are collected and controlled by the internal microprocessor system and then transmitted to the computer for further processing. The system’s accuracy now facilitates production within 0.1% H2O below the legal limit without exceeding it.
