Pitching of Yeast

Description

Application

The yeast pitching system YeastPitch doses yeast cells fully automatic and homogeneously into the juice stream.

Description

The yeast pitching unit is a fully automated system that measures and controls the addition of liquid yeast into the juice 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 fruit juice. Variations in the basic turbidity of the juice 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 juice together. The yeast cells are homogeneously distributed throughout the fruit juice by a Vortex effect inside the injector. Due to its compact and modular design, the skid can easily be combined with a juice aerating system.
