I spent most of the afternoon yesterday messing with roasting stuff. I
bought one of those round flour sifter thingies and reworked my colling
setup completely. Now I am most happy with it. The sifter is 12" round and
about 3" deep with solid sides and a 1/32" mesh bottom screen. I bought it
for about $28 (incl shipping). I bought a new plastic storage bin for about
$9 at Wally-world. It is about 18 in. wide, by about 2.5 ft long and a foot
or so deep. Yeah - it's a big 'un. I put the hole in the lid near one end
and cut the hole for the blower on the end of the body.
I am using the leaf blower on the outside blowing in - this removes the
chaff well. The blower has enough flow rate and head capabilities that it
does tend to blow a bean or two out, so I use one of the heat-resistant
gloves to lay across the air inlet for the blower to throttle the intake and
modulate the flow. This brings it easily under control. It cools a 1-lb
batch to "near ambient" quickly - maybe 2 minutes.
The flour sifter works better then my previous try using a sink strainer,
since the sifter has solid sides and less air bypasses the beans being
cooled. The larger bin helps to tame the turbulence that makes the flow
across the beans uneven. I was using the blower on one end and the lid
turned so that the sifter was on the opposing end. I will try it next time
with the sifter on the same end as the blower inlet.
I roasted 3 1-lb batches yesterday to test the cooling setup, to
re-familiarize myself with the RK drum, to reduce my stash of older coffees
(gifting some folks with some of it) and to reinforce my own roasted supply.
Last week I found about a 1/3 # of the last available Gesha Esmeralda in my
stash when I was digging out the Kona and Aussie coffees to roast for my
sister's birthday gift. (NO - she didn't get the Gesha. YES - I am
selfish.) We had Aeropress Gesha for the 4th. It is still a *WOW* coffee.
Next time, I will work on 2# batches and see how the cooler handles that.
