Coiled Liebig

Postby grunger » Wed Mar 02, 2011 1:21 pm

I'm talking with a guy in town who makes wort chillers like the one pictured below. I'm trying to decide how large to go with this.
I was thinking 48" length with 3/4 OD with 1/2 ID.

I'm looking for something that can really knock down a lot of heat for stripping.

Thoughts?

A graham is a coil inside a housing, where the coolant flows around the coil and the product through the coil. A tube inside a tube is a liebig. That looks to be truly a coiled liebig

That looks like the counter-flow wort chillers that homebrew companies sell. I hadn't thought of using one on a still. Great idea.

That's what this is. I asked him to make a custom one for me and he said to send him the specs and he'll do it.

1" over 3/4" for the higher cpacity. You won't have to worry about turbulators or anything because of the spiral. Should be sweet.

I'm going to get him to leave larger gaps between coils so the condensed product exits faster.

Can't imagine that not doing a top notch job.

I bet if you could figger away to engineer that thing into the "Graham" configuration........like a triple walled Graham........alah wort chiller in a jacket..........Use the middle chamber for vapor/distillate,,,,,, you could throw the fire of hell at it and it would just keep knockin it down..

Just thinking about my perfect word out loud.

The longer it's in the condenser the cooler the output? 4 feet of cooled tube would handle 4.5 KW no problem I bet. Do you have a price yet?

OK, now you got me thinking! You would have to do more than just design a triple walled Graham, with a Graham configuration it really needs to hang vertical so you would have to keep it away from a propane burner unlike a liebig that can take off at an angle. Got to give that design a little more thought but has great possibilities.

He charges $120 for a 12 foot wort chiller. Not sure on this modified design. We haven't discussed dollars yet

That's what I was getting at. If I go with a smaller diameter pipe but longer length I want the condensed liquid to exit the pipe so that it does not surge.
