Abstract
A technique related to a fermentation process; where a signal processor receives a signal containing information about an amount of entrained air in a mixture forming part of a fermentation process in a tank; and determines a level of foam in the tank based at least partly on the amount of entrained air in the mixture. The signal processor may also provide a control signal for controlling an amount of defoamer (or antiforming agent) added to the mixture in the tank so as to control the production of foam within the tank by controlling the amount of defoamer added to the mixture in the tank.
