Topic: moka kadir first roast (10 msgs / 225 lines)

My wife got me 5 Lbs.  of moka kadir for my birthday.  Roasted up a =
batch in my FR+ and it took 10 1/2 minutes to reach 2nd crack!  Chalked =
it up to different roast characteristics, maybe cold roaster.  2nd batch =
too long, still:  8 1/2 minutes.  Starting to get concerned.  Roasted a =
batch of Guatemalan Coban Tanchi, which my log book shows 4 minutes and =
30 seconds to a rolling 2nd crack in past roasts, and after 8 minutes I =
ger a few lifeless snaps of 2nd crack.
Got my backup base down, which has a broken timer but the microswitches, =
heater and fan all function.  Another batch of the Coban Tanchi & I get =
the same result.  I then ohmed out the heater coils of both bases, get =
around 20 ohms.  They are both so close that I know that I don't have an =
open coil.  Then I think, here in Georgia we are heading for a record =
low tonight.  I wonder what the power line voltage is?  108-109 VAC!  No =
wonder!  I work for Georgia Power, and have never seen it that low.  It =
is usually 118-120 V, rock steady.  Hope we don't have brownouts, =
tonight-they are having a hell of a time getting Branch Unit 3 on line =
tonight.
So, the real question is-did I ruin those beans with the slow roast?

I wouldn't think so. I deliberately slow my FR+ to roast in the 12 to 14 
minute range with a variac. Should have reduced brightness, but more 
body and character. Try it, you might like it.

Nope,   I regularly aim for a 17 to 18 minute roast.

If you're lucky, they'll be more chocolate than 
fruit. If you're unlucky, they'll be sweet and 
otherwise pretty tasteless. In any case, it's 
certainly worth a try.

Mike,
 
Your own taste will be the final arbiter, but many people go to great
lengths to slow down the 'stock roast' of the FR+ and other air
roasters.  I personally prefer the results of a slower roast -- maybe
you will too.  Of course, if you do, then once your line voltage is back
up to normal, you'll probably find yourself in the market for a
Variac...

Lee,
I wrote it up in some detail a while ago, and can't find it now. Try to 
search the archives.  The simple answer is remove the timer, and attach 
the power cord across the heater coil (variac this). Then pull the 
bridging diodes off the fan, and run the fan off of a 12v DC wall trans.

Well let's see, in addition to the usual bottom of the roasting chamber
coming unstuck from the glass, it seemed to be roasting cold, yielding
stalled roasts.
I was thinking perhaps if I can put the heating coil on a variac I might
be able to compensate by supplying higher than 100% power at the crucial
points of the roast that require high heat (and turning it down to
lengthen the roast at other points).

You might have a 'cold' one. If this has been normal there is a thermal 
switch inside that you can solder shut. Basically just like an air 
popper. As part of my variac mod, I soldered mine shut so that it could 
open and throw off my profile.
