Milling system for breweries
Enhance your brewing process with a system that conserves grain husks while optimizing endosperm grinding, ensuring higher wort quality and flavor stability.

Processes Grain for Brewing with Integrated Steeping
The GEA MILLSTAR® milling system combines efficient grain processing with innovative steeping conditioned milling, ideal for breweries and beverage manufacturers aiming to elevate their production process. By preserving husk integrity while optimizing endosperm grinding, the system supports the production of ales, lagers, stouts, and more, ensuring maximum wort quality. With capacities ranging from 5 to 40 tons per hour, the MILLSTAR® suits both continuous and high-capacity operations, integrating smoothly into existing brewery setups. Advanced automation allows precise control over steeping time and crushing roller adjustments. The system’s compact design reduces footprint, while its robust construction ensures minimal maintenance. Optional features include inert gas flushing for reduced oxidation and large rollers for effective husk conservation, supporting operational efficiency and product consistency.
