The automatic pitching rate control  system ensures that an accurate amount of viable yeast slurry is delivered from a Yeast Storage Vessel to the Fermentation  Vessel within a defined period. The brewer sets the target amount of yeast required and the timing of the pitch within the brew.

During pitching the system then monitors the concentration of yeast passing the probe in the pitching main. The resulting concentration signal is then integrated with the output  from the flow meter, giving a measure of the volume of viable yeast pitched into the  Fermentation Vessel. When the target is reached the controller will turn off the yeast pump.

The system may be modified by the addition of a flow meter in the wort line to enable the wort flow to control the viable yeast rate and hence provide continuous pitching over the whole brew length.
