Pitching of Yeast
The yeast dosing unit YeastPitch is a fully automated system that measures and controls the addition of liquid yeast into the wort line with extreme precision.
In the standard design the skid is equipped with accurate flow meters. Optionally, turbidity sensors or a live yeast cell monitor can be used. Differential turbidity measurement before and after yeast dosing ensures that the right amount of yeast is dosed into the wort. Variations in the basic turbidity of the wort are automatically compensated for.
As an alternative to differential turbidity measurement, the dosed yeast can be controlled by in-line live cell measurement. A specifically designed injector then blends the yeast and the wort together. The yeast cells are homogeneously distributed throughout the wort by a Vortex effect inside the injector.
Due to its compact and modular design, the skid can easily be combined for example with a wort aerating system. The system can also be designed for dosing yeast into juice as required for the production of cider and wine.
