Inline aeration/oxygenation unit for beer
Ensuring the consistent fermentation of beer often requires precise control of oxygen levels during wort aeration. Insufficient aeration can inhibit yeast reproduction, while over-dosing can lead to undesired substances and excessive foaming.
Control oxygenation and aeration in beer production
The Bucher Unipektin inline aeration/oxygenation unit is designed to provide accurate and automated air and oxygen injection into beer wort. Using the Bucher Denwel Injector, the unit splits gas into microbubbles, achieving efficient saturation with minimal pressure drop. The oxygen or air can be sterilized using micro and sub-micro sterile filters. An inline oxygen analyzer continuously monitors concentration levels, while a PLC system processes the output signal to control dosing. The high precision control valve adjusts injection rates to prevent over or under-aeration. It comes with Tri-clamp connections and operates under pressures between 2 to 5 barg and temperatures from 0 to 15 °C. This unit can handle air addition up to 15 ppm and oxygen addition up to 25 ppm, depending on pressure and temperature. Sizes range from 20 to 1000 hectoliters per hour.
