Yeast propagation system for breweries

Propagates and Maintains Yeast for Beer Production

The GEA YEAST-STAR® Yeast Propagation System is a comprehensive solution developed by GEA for breweries and beverage manufacturers to optimize yeast health in beer production. This system is engineered to provide vigorous, actively fermenting yeast with a unique hygienic design, ensuring the preservation of yeast viability and vitality. By incorporating optimal aeration rates, a gentle circulation loop, and a sterile air station with a candle filter, the system minimizes foam formation and guarantees homogeneous mixing.

This yeast management solution is tailored for brewing processes like lager, ale, stout, pilsner, and even non-alcoholic beer, ensuring high-quality outputs. It supports continuous and automatic operation, facilitated by a frequency-controlled pump and controlled overflow valve to compensate for variations in yeast consistency and wort flow rate. The differential turbidity measurement method accurately determines yeast cell count, and the system’s static mixer ensures proper integration of yeast into the wort.

The system’s compact design integrates seamlessly into existing production lines, using VARIVENT® components for superior hygiene and CIP ability. With sizes ranging from DN 50 to DN 150 for wort pipes and a yeast pitching range of 5 – 50 million yeast cells/ml, it offers high flexibility and can handle a product flow rate of up to 1900 hl/h. For precise operations, it incorporates linkage to master control systems via a serial interface, supporting both automation and remote monitoring. Suitable for a range of industries, this system is engineered to adapt to space constraints and budgetary considerations, providing an efficient and reliable yeast management solution.
