How WORTSTAR® works
Designed for optimum yeast activity, flotation and precise fermentation curves for top-quality beers. WORTSTAR® creates a partial vacuum where air is entrained with the wort for improved bubble size and distribution. This increases the surface area for greater contact and oxygen uptake.
The fully automatic wort aeration model includes an automated product trap to prevent liquid passing through into the air pipe. Suitable for DN 40 to DN 125.
A semi-automatic wort aeration unit is also available for craft brewers (suitable for DN 25 to DN 50).

GEA Insights
The breakthrough that changed spray drying
In 1976, NIRO engineers responded to a competitive challenge by rethinking what spray drying could do. Their idea became the multi-stage dryer MSD. Fifty years later, the same fundamental principle helps turn liquids into the powders used in essential nutrition products and important medicines around the world. Refined through decades of engineering expertise, customer insight and continuous development, MSD is a story of innovation with lasting impact.
Beyond the machine: unlocking better plant performance
An efficient machine does not automatically make an efficient factory. Real improvement often starts by looking beyond individual equipment and understanding how processes, energy systems and operating decisions affect one another. It’s a holistic approach designed to uncover opportunities that might otherwise be missed.
How a valve reshapes the way food and drinks are made
In food and beverage plants, valves are commonly operated using compressed air. GEA Hydract® Actuation Technology moves valves with water instead, in a closed, digitally controlled circuit. The result is a valve that can be held exactly in place and steered in fine-tuned steps. This results in lower energy use and greater control.
