I've been using an immersion chiller for a while now, and I don't feel
that they're too hard to clean.
Prior to use, I run hot tap water (~180 F) through it from the tap for
about a minute (full 60 seconds) after it's hot at the far end at a
fairly high flow rate. Then I fill it (with a funnel) with a
Chlorinated TSP solution, and let it sit in there for about 30 minutes.
Then the hot water rinse is repeated again for another full minute.
The chiller is then stored with the copper tube left full of water.
I always check the first rinse water out of the tubing (smell, then
taste) prior to the full first hot water rinse, and I've found no
problems with it. A friend goes a little further and uses live steam
from a pressure cooker to really sterilize the inside of the copper
tubing. He's had no problems either.
On the rubber hose surrounding the tubing, I recommend the use of a hot-
water rated hose.
I've made up a diagram and condensed instructions for a friend or two
for making one of these, and since it's done, anybody who wants a copy
can send me a self-addressed stamped envelope, and I'll send it back out
with a copy of the instructions. Only 1 stamp, since it's only 1 page.
Send the envelope to:
418 San Benito Ave.
Los Gatos, CA 95030-9305
