Brewing yeast needs oxygen to multiply. While insufficient aeration results in reduced yeast reproduction, over-dosing may cause the formation of undesired substances and wort foaming. Therefore, controlled wort aeration is required for a consistent fermentation rate and constant product quality. Designed for fast and accurate injection and dissolution of air or oxygen, Denwel provides a fully automated solution for continuous wort aeration.
Oxygen or Air is injected into the wort through Denwel Injector, which splits the gas into microbubbles. Most efficient and instant saturation of the gas is achieved with only a minimal pressure drop, no gas loss and fully hygienic design. No static mixer or sinter candles needed. The injected gas can be cleaned and sterilised by micro and sub-micro sterile filters. An inline O2 analyser continuously monitors the O2 concentration. The output signal is processed by the PLC to control the O2 dosing. A high precision control valve accurately adjusts the injection, avoiding any over- or under-aeration/oxygenation.
