hello everyone,
I've been trolling around for a bit and I have a question that I can't seem to find an answer for.
After a few batches of very basic all extract brews, I can no longer fight the pull of my DIY nature. my first project is a wort chiller. a counterflow design seems easy enough and I've seen many versions all over the internet. every design I've seen so far has the wort flowing through the inner pipe, and the coolant flowing in the outer pipe. am i wrong in presuming that the wort would cool faster if it was flowing through the outer pipe, so that it's spread thinner and is being cooled by two different surfaces, the inside pipe with the coolant as well as the air temperature on the outside. is there a design flaw here that i'm missing?
Secondly, if this design is viable, why not incorporate an immersion along with the counterflow. The design I'm envisioning is an all copper counterflow chiller that is built into a 5 gal bucket. coolant and hot wort go in the top as usual, and exit on the side of the bucket at the bottom. the bucket is filled with ice water. in the end you have a thin spiral cylinder of hot wort being cooled on both sides.
please explain why this will or will not work!!
