This is the inoculation bleed valve. If you remember from the diagram, yeast and enzyme sends me inoculation to add to the fermenter. Inoculation is basically a liquid form of yeast to help the mash in the fermenter to start fermenting more quickly. Since it is yeast, which is a plant, if things are too hot, the yeast will die, and not work. So before receiving inoculation, the fermenter operator tells me that the temperature is cool enough to inoculate, which is 95 degrees. So I radio to the guy, "24, we're ready to inoculate." He responds, "10-4." So after he sends it, I wait for it to come out of this bleed pipe. After it comes, then I open a valve so that it is added to the fermenter with the corn mash.
