WORTSTAR™ − From semi- to fully automatic aeration solutions.
First time at BrauBeviale 2014: With the wort 
aeration system WORTSTAR™ GEA Brewery Systems has developed an aeration unit that is an innovative concept compared with other conventional aeration systems. The unit treats the wort gentle and works efficiently.
Customer benefits at a glance
- Optimum oxygen uptake
- Consistent hygienic design
- Completely pre-assembled and factory tested system
Top marks for a novel aeration principle
After cooling the wort is oxygenated to increase yeast activity and to start the fermentation process. 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.
The GEA aeration unit – easy introduction of sterile air into the wort
With the aeration unit, sterile air is introduced into the wort through the defined annular gap of the annular gap nozzle. The complete annular gap nozzle can be CIP cleaned and sterilized with steam. The system is the standard for obtaining the optimum yeast flotation and activity, and more precise fermentation curves. This guarantees superior quality beer.
The product trap – a main component of WORTSTAR™
The product trap is an important component of the wort aeration. It ensures that no liquid is pressed into the air pipe due to pressure shocks in the wort pipe. The product trap consisting of a stainless steel container with integrated sight glass, spray ball and level limit switch. The level limit switch indicates when the filling level is reached. With this feedback signal, the supply from the air pipe to the aeration nozzle is closed.
