Top Marks for a Novel Aeration Principle WORTSTAR™ Wort Aeration System

After cooling the wort is oxygenated to increase yeast activity and to start the fermentation process. To ensure the necessary air or oxygen supply into the wort stream we have developed an aeration unit that is an innovative concept compared with other conventional aeration systems. Our unit treats the wort gently and works efficiently.

When the wort flows into the aeration nozzle, it creates a partial vacuum and air is entrained with the wort. This leads to an excellent bubble size distribution and thus to a large contact surface for oxygen uptake by the wort.
 
This is one of the many reasons why an independent examination and assessment carried out on several different aeration devices gave top marks to the GEA Brewery Systems unit. The system is the standard for obtaining the optimum yeast flotation and activity, and more precise fermentation curves. This guarantees superior quality beer.

Design

• Completely pre-assembled system in compact design with electrical and pneumatic installation
• Simple installation - installation and commissioning can be done by the customer
• Fine and even introduction of air into the cold wort through an annular gap nozzle
• Two wort aeration units connected in parallel for higher throughputs.
