I guess what I'm wondering is how much effect the inlet/outlet size has on the pump's ability to handle grain in mashes. The one I've seen in use was 3". Is 3/4" far too small?
You use electric elements in the jacket right? How did you insure that the localized temp didn't reach the smoking point? Or perhaps even minimal smoking isn't an issue since the jacket is sealed?
I ran some tests using an immersed element inside a 2" stainless tube immersed in peanut oil and there were wisps of something (I thought smoke) coming from the oil within a few seconds. Perhaps the larger volume of a jacket would help, but I don't know how much at this point.
Out of curiosity, would these work as heat transfer fluids?

I think most craft distillers would hope their product stands on its own legs. That said, I get what you're saying, but how many custom wine/beer bottles are there?
FWIW, feel free to post or PM what your rough costs for a custom bottle are.
Are the .1 scale high precision hydrometers from HB Instruments worthwhile? They seem to be taller which would be a good thing but is there appreciably more space between the graduations for the expensive .1 models vs. the inexpensive .2 ones?
The .1 high precision ones seem to be rarely mentioned here which is why I wonder if they offer useful precision for our purposes.
Thanks, that was what I wanted to clarify if people were willing to share. Its not hard to plug some volume and ABV into a calculator and get the theoretical grain sizes.
Would fermenting in a conical and dropping/removing the solids as it ferments accomplish the same thing as filtering?
Wouldn't distilling also remove any smell?
Are you referring to adding copper while distilling or fermenting?
Interesting idea. With the mash already roiling from a boil, would you need to worry about directly immersed elements burning an "on the grain" mash? Has anyone using immersed elements ever burned the wash _after_ the boil started?
