This is the Boiler. After the grain has been mashed and sparged, the wort is
drained into the boiler tank. The wort is brought to a boil and hops are added
at various intervals for bitterness and flavor. The boiler tank is another
Sanke keg that was purchased through
Homebrew Heaven
. In addition to the drain port, I had them add two additional ports. These
ports have quick connects on the outside and a 40 foot long coil of 1/2"
copper tubing. There is also a SS screen that was purchased from
Stainless in Seattle
. This filters the hops from the wort when transferring the wort to the
fermentor.
In many ways, this vessel looks a lot like my liquor tank. What's different
about this setup than most is that I have chosen to mount the immersion chiller
directly through the wall of the boiler tank. Typically, about
half way through the boil, the immersion chiller is put into the
boiling wort in order to sanitize it. Once the boil is completed,
tap water is run through the immersion chiller to cool the wort.
Once the wort drops below 110°F or so, the wort is susseptable
to contamination by a bunch of different nasties (airborne
bacteria and yeast). Thus any opening is a potential source for
ruining your beer. By going through the side walls, I am able to
place a well sealing lid on the boiler tank to minimize any
contamination.
I always disliked fiddling with
the immersion chiller. I'm hoping this will simplify my brewing
day (and that's half the reason for a HE-Man RIMS). It may make
it too difficult to clean the hops from the boiler as I can't
remove the screen without removing the coil (which I don't plan
to do). We'll see how this works out over time.
Note that my liquor tank used a
coil cut down from a 1/2" x 50' immersion chiller. The coil
above was bent from 50' of 1/2 copper tubing purchased at Home
Depot. This coil came in the form of an Archimedes spiral and had
to be re-formed to the current design. I was chicken at first
that my coil would come out looking rank. hence, I used a
purchased coil in my liquor tank. With a little help from my
better half, I placed one end of the coil into the spigot hole of
my fermenting bucket. While Debbie held the bucket, I coiled the
tubing around the bucket.
It came out looking great and much
better than expected. I wish I had done the other coil this way.
I would have saved about $25. I prefer the larger diameter of the
coil in the boiler as it will give me more room to stir. If I
choose to bail on this permanently mounted immersion cooler, I
will swap this coil with the one in the liquor tank, buy a new
boiler and sell this one off as a liquor tank.
