Yeast dosing

In breweries, wort lautering is followed by addition of the yeast necessary for fermentation. The amount added is checked automatically by detection of the turbidity value.

Because the wort contains so much turbidity matter, the instrument is set up to measure the scatter coefficient by the transmitted light method.

Since the turbidity value of the wort is already quite high, turbidity is measured before and after yeast dosing. The values of the two measuring instruments are subtracted in the control unit and converted into million cells/ml with a scale factor.
