WORTSTAR™The GEA wort aeration system

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. Our unit treats the wort gently and works efficiently.

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.

GEA aeration unit – annular gap nozzle in detail

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.

Your benefits at a glance:

J Hygienic safety due to integrated product trap J Continuous and exact wort aeration thanks to fully

automatic control J Fine and even introduction of air into the cold wort

through an annular gap nozzle J Optimum oxygen uptake by the wort is ensured due to

finest air bubbles J Consistent hygienic design J Easy CIP cleaning J Completely pre-assembled system J Air pressure monitoring J Optional switch cabinet, pre-wired and factory tested

Technical data:

J Capacity range – 125 hl to 1,250 hl per hour J Standard sizes (wort pipe) – DN 50 to DN 125 J Wort flow rate – 1.0 to 2.5 m/s J Pressure loss wort pipe – Max. 1.5 bar J Air pressure – 6.0 to 8.0 bar Ü J Control – Fully automatic
