Seeking an explanation as to how a combined kettle/whirlpool actually works - I have not been able to find an explanation yet and I have never seen one.
My guess is that there is a draw nozzle on one side of the vessel connected to a pump which returns the wort through another nozzle, thereby imparting rotational momentum on the wort still in the kettle. The bulk wort slowly begins to rotate, and the trub collects in the middle. Then, when happy that all of the trub is in the middle, you disconnect the return hose on the discharge of the pump to your plate HEX and transfer the wort to the fermenters.
How is this for a guess?
Any hints regarding nozzle design, location, other issues?
Thanks.
