Topic: i-roast from ebay (4 msgs / 152 lines)
1) From: Robert D. Crawford
I just received an i-roast from ebay.  I feel like I got a good deal but
some time will tell.  Since this is from an auction, as is the usual
case no documentation was included.  I have a few questions I am hoping
someone can answer for me.
1.  I am not sure if this is an i-roast 1 or 2.  I see that there is a
warning sticker on the back concerning over use.  This leads me to
believe this is a 2 model as I have heard that this warning was brought
about on the 2 because of warranty claims.  The front says i-roast but
neither the front or the bottom say anything about version numbers.
2.  I have to order a chaff screen.  If I filter the beans in a mesh
colander can I use it while I am waiting for it to come in?
3.  I seem to remember a www site with a list of profiles but I cannot
seem to find it searching the archive or via google.  
I still have to do some more googling concerning the programming and
features for the roaster I have but I need to know which one it is
before I can know about instructions.
If anyone has extra tips or gotchas that are not on the SM tip sheet I
would welcome them.  I just finished a 130g roast of Sulawesi |Grade One
Toraja  on preset 2, but I think I got it a bit dark... actually, it is
black as night and oily as crude.  Good thing I like Italian roasts.
Thanks for any help you can give.

Robert -
(1) I have an iRoast-1, and it has the same warning sticker on the back.
     The pictures I've seen of the iRoast-2 show a number '2' through the
     'o' in 'Roast' on the logo on the front. Sounds like you have the
     iRoast-1 (whose logo simply reads 'iRoast'). Bottom line is if you
     can program more than three stages into the profile, it's an iRoast-2.
(2) I would not use it without the chaff screen insert. The small
     mesh opening in the top lid will clog pretty quickly, which could
     lead to problems (possible overheating and having the roast progress
     too quickly come to mind).
(3) I don't know of a list of profiles on-line, but Tom's tip sheet is an
     excellent starting point and is what I used. There is enough variation
     between machines to make profile lists somewhat meaningless for the
     iRoast.

   Roasted 4 batches of Kenya Auction Lot 405 - Mchana Peaberry (April 2006)
   to a perfect City+ in my iRoast-1 yesterday, and just finished drinking
   the first pot. A truly wonderful "laid back, So-Cal Kenya" (Tom's words).

Mine does not have the 2.  Not a problem, though.  I really cannot see
myself using more than 3 stages in the roast.

Good thing my first roast was with a bean with very little chaff.  Looks
like I'll be having my partner order a screen in the near future.

This is also good to know.  Do you use the presets at all and if no why
not?  I am moving up from a FreshRoast and never used anything too
fancy, just a 1 minute heat 5 second fan-only for slowing the roasts.
Thanks for the response,

I have only wanted more than 3 stages on rare occasions, but not enough
to upgrade the machine. Tom's advice on his tip sheet to use the first
two stages to 'get to the door of first crack' have served me well.
<Snip>
I'll also add here that, by design, the chaff screen insert adds some
restriction to the airflow. This has an effect on the temperature of
the air flowing through the machine.

I've never used the presets. Users had reported that they produced coffee
that was way too dark. In addition, I have one of the early iRoast-1's
that runs on the hot side.
Instead, I usually start with what I call my 'standard' profile when
roasting a new coffee, then make adjustments on subsequent batches.
For my particular setup, my standard profile is:
  325 F for 3:00
  385 F for 3:00
  390 or 400 F for the balance of the time
(390 F for lighter roasts and 400 F for darker ones).
I then hit 'Cool' when I want to end the roast.
On my unit, the fan runs on high for programmed temperatures up to 385 F,
and runs on low for settings of 390 F and above.
My setup includes the vent adaptor, which I route to a board with a hole in it
that fills the opening in window. This increases the back pressure slightly,
resulting in a hotter profile. The advantage, however, is that I'm always
roasting indoors at a known and fairly constant ambient temperature, allowing
me to reproduce my roasts pretty consistently.
The other huge improvement I made was the addition of a temperature probe in
the bean mass. Although this does not really measure the temperature of the
bean itself, over time it has enabled me to judge when a given bean is close
to a given roast level. For details on this, see:http://jbensen.home.mpinet.net/and click on ' iRoast-1 Temperature Probe Mod'.
Others on this list have done a simpler temperature probe setup using the unit
from SM and routing the fiberglass-encased probe wire between the glass and
the rubber gasket near the bottom of the roast chamber, leaving a short amount
to protrude into the chamber.

   Drinking a melange of Hawaii Kona - Mountain Thunder Fancy and Hawaii Kona -
   Moki's Farm (both Dec 2005), City++, 50/50 pre-roast blend (since I did not
   have enough of either one for a full batch in the iRoast). A little long in
   the tooth, but still quite excellent!
