The solubility of oxygen in wort is temperature-dependent. The colder the liquid, the better the oxygen solubility. Therefore, aeration is carried out after the wort has cooled. The amount of oxygen or sterile air to be added to the wort depends on various factors, such as the original gravity, yeast type, and desired properties of the final product. The Wort Aerator can be designed for manual or fully automatic operation. Automated systems measure and control the O2 content of the wort with the highest precision using an optical OXYTRANS sensor from Centec. Centec has decades of experience in developing and manufacturing its own precision instruments for O2 control. Based on oxygen and flow measurement, the amount of oxygen supplied is precisely adjusted to the measured wort flow. For O2 injection, the Wort Aerator features a specifically designed vortex-Venturi injector that doses oxygen directly into the product stream in a very large number of very small bubbles. Due to pressure and turbulent flow, the oxygen dissolves completely and absolutely homogeneously in a very short time. A control valve can be located at the end of the dissolution section to maintain constant pressure in the system, above the saturation pressure. The Wort Aerator is equipped with a sterile air filter system to disinfect the supplied gas.
