As the lauter progresses and sugars are carried into the boil kettle (or holding kettle, whichever you have) we've been able to speed up our draw-off speed due to the decreased visosity of the run-off. We obviously have a valve restricting flow for back-pressure, as well as a VFD for flow rate control. My question is this:
Is it better to use the VFD to increase speed towards the end of the lauter or the butterfly valve, and why?
We're simply looking to cut some time off our lauters and have been doing so by opening the "restriction" valve a little more as the lauter progresses. Just curious which one would be better and for what reason....
Cheers!
