Sensors for use in food applications that can withstand CIP cleaning and deliver accurate, reliable measurements.




Fermentation


During fermentation the pH drops to about 4.1-4.2 and in some cases even lower. The further acidification of the wort helps to prevent bacterial infection, because most bacteria cannot tolerate acid pH. Yeast can survive at very low pH, as low as 2.0. This is the basis of acid washing where the bacterial load of a yeast slurry is reduced prior to repitching by lowering the pH to 2.2. Most bacteria will be destroyed at this pH while a good percentage of the yeast will survive.

Although the acid does help to balance out the flavor, it will inhibit fermentation and therefore should only be added after fermentation is complete.

Conductivity Sensors for Fermentation



Goal of Measurement:
After fermentation the beer is pushed out of the pipes with the help of water. The switch from beer to water results in a change of the conductivity which can be recognized by the conductivity sensor installed in the pipe. With the use of a conductivity system the process of media separation can be fully and easily automated.
