Topic: New Roaster - Aerorost II (6 msgs / 145 lines)
1) From: Mark Norgren
Newbie and a relatively new roaster.
I just bought a Aerorost II from a company in Minnesota. http://www.cafecoffees.com/ It allows me to roast as much as 2 pounds at
once.  This weekend I roasted 4 pounds for the first few batches.
I started to get the hang of the first and second crack pretty well after
the second batch.  All of the batches taste great.  I roasted Columbian,
Sumatran and a Java.  
My question surrounds this roaster and if any of the other readers are
using is.  I am getting my first crack around 21 to 26 minutes and pulled
the beans around 27 to 33 minutes.  I am cooling the beans with two
colanders, pouring back-n-forth.  This was very effective for cooling and
taking the chafe off the beans.  Should my machine be taking that long??  
Any advice would be great.  I have a Saeco Magic Deluxe Superautomatic for
espresso and drink that mainly.  Hence my roast are a dark roast.
Any thoughts?

No.  You need more heat, otherwise, you'll end up with a lot flatter taste profile
than you want.

 I'd like to know more about your roaster.
Currently, I'm still learning how to roast using popcorn poppers.
But, in the back of my mind I can see myself wanting to make bigger batches.
2lbs sounds good to me.
 Earlier tonight I was checking out a place called www.buzzroasters.com and they make 2 and 4 lb. BBQ roasters. Nifty.
On his site he made a great bean cooler using a shop vac, a 5 gallon plastic bucket, with a lid, and a collander. Basically, you take the lid of the bucket, cut a hole in it to fit the colander. then you drill another hole near the bottom of the bucket to fit the hose of a shop vac. when you are ready to dump your beans, yurn on the shop vac, and 1/2 min. later, they are cool. I'm making a smaller 1 gallon size 'cooler',  this weekend.
Just thought you might like to take a look at it.
Gary, just glad the list is working again!

From what I've read about your roaster, it's important to go through a
warm up cycle before roasting.  This will bring first crack much sooner
(12 minutes) and shorten the entire roast to under 16 minutes if I
recall correctly.

Good point on preheating. Also all electrically heated roasters are
sensitive to line voltage, lower voltage equals longer roast. Make sure you
have 120v. If not you'll need a variac (variable auto-transformer) to
compensate. Tom sells a reasonably priced 20A one. Ambient temperature also
a factor though likely not a problem this time of year.
If voltage ok then I'd suggest reducing batch size to bring roast times
down, shooting for 14 to 18min. Roasts taking upwards of a half hour are
going to be rather flat lacking any decent acidity IMO.

Ron Kyle on this list makes drums too, and I think a few here would vouch for
their quality.
