Topic: Re; colander cooling for RK drum? (4 msgs / 88 lines)
1) From: James Savanella
I know I've seen details here on how to set up a colander and shop vac to cool beans out of the RK drum. Can anyone enlighten me?
  My current design does not allow the chaff to go through the openings in the colander. The holes seemed a little small so I drilled them out to 1/4 and still not much luck.
  Thanks

1/4 inch should be large enough to allow chaf to pass through if you =
have enough air flow and are stirring the beans. I use a 20" box fan and =
a 16" sifter and the chaf blows up and out. I would rather have it =
sucked down but have not tried making one that will do that as of this =
date.

James,
Part of the problem may be the amount of airflow going through the holes =
where there are no beans means that very little air is being pulled =
through the beans.  I adapted a SS mixing bowl to fit over the bucket, =
and drilled holes only along the flat bottom.  It worked fine, but I =
wanted more capacity. Then I switched to a 9x9 tupperware piece, which =
has the bottom cut out and replaced w/ two criss-cross layers of " =
hardware cloth.  The tupperware fits into a box now, instead of the old =
5 gallon bucket.  If you can roast and cool outside, a box fan blowing =
up though the beans works great too.

You can check my website (link below) for pictures of my cooler. Even
though I have a 2 inch vacuum attached it is running throttled down
and I have no problem removing chaff through 3/16 inch holes that are
drilled in the bottom of the colander, not the sides.
Try the following test: Without any beans in your cooler and with the
vacuum running you should not be able to easily remove the colander
from the pail. If you can then you either have too many holes, not
enough suction or a poor seal someplace.
I agree with earlier replies about air flow and also stirring the
beans while cooling.
