The Yeast Monitor  probes are installed in yeast recovery lines. This system utilizes the Yeast Monitor to control yeast recovery, thereby ensuring that waste is minimized and storage of good viable yeast, suitable for re-pitching is maximized. The controller sets the yeast strain of interest and initiates run down.

The first set point determines when the yeast concentration is sufficiently high for the flow to be diverted to yeast storage. The first portion of the process containing non yeast matter and low concentration yeast is directed to the waste tank. This is followed by the storage and logging of yeast with a viable concentration suitable for re-pitching. Finally, once the second set point is detected, the system completes the process by diverting the flow to green beer processing.
