Topic: roasting 1lb in Behmor question (10 msgs / 227 lines)
1) From: Stephen Carey
Hi, all.  I have put off roasting a full pound in the Behmor because 
I am just too afraid of screwing things up.  Well, I got over that 
and figured out that the only way I was going to get good at 
roasting, no, change that, get very good to excellent at roasting, 
was to take chances, make mistakes and learn.
I have a lot of Sumatra Blue Batak "Tarbarita" Peaberry, over 5 
pounds in hand.  I have only roasted it in the IR2, with very good 
results.  Well, something came up and I was asked, on very short 
notice to provide a pound of coffee for an event.  I have 36 hours of 
rest time, at the least, possibly a bit more.
So, I decided to use the Behmor and roast one pound, at once,  After 
all, it says it can do it.  Not having truly worked out a profile for 
this roast I used the Behmor safety standby, Profile One.  I roasted 
the full pound, and took it to 19 minutes and am fairly happy with 
it.  I need to taste it to know for sure, but the crunch taste test 
was quite good.
Here is where I had problems.  The first crack was distinctive, but 
oh so slow, very slow.  This may be normal for a bound of anything, 
but my notes from my IR2 roast (and a much smaller batch) don't 
mention this at all.  It finally finished the cracks and I wanted to 
stretch it out to City + or a bit more.  So, I let it go a bit longer 
and then it went into cool, which I know does not mean an immediate cool.
This machine is always hot enough for roasts and I am very happy with 
it.  My question is one of other people's experience.  Does a one 
pound roast normally have a slower first crack, versus the rapid fire 
of some roasts (and different beans)?  I realize there are a lot of 
variables in here and I also know that I won't know how this coffee 
tastes (other than the very small pot I am making now) until a small 
wake in about 36 hours (and where they won't be thinking of my coffee 
- I am not that vain, promise.)
I just like to learn, even if I have screwed up.  I tell you, I am 
roasting up a storm.  I used to let the fact that I am the only 
coffee drinker in the house slow me down, no more.  I have people 
over.  I take it places.  I offer to bring it to parties and the 
like.  It allows me to roast more, taste it and see what I like, and 
get the opinion of others (though that matters least, for they are 
not looking for what I am.)  I can say that I have received a number 
of compliments by people who DID NOT know I roasted the coffee, that 
is always cool.  Actually, the host received the compliments and 
pointed the person in my direction.
That's it.  Just looking for some feed back.
Have a great day,
Stephen

The trick to doing 1 pound roasts is...
`1) pre-heat the machine on 1 pound P1 for 2 minutesThen cool for 2 minutes
 2) Add the beans
3) After roast is done and cooling cycle begins 2 minutes into the
cooling cycle remove the chaff tray
allow the cooling cycle to finish without the chaff tray in place

I do NOT believe Joe recommends the pre-heating of the roasting  
chamber. Alchemist John probably knows if this is recommended or  
discouraged.
Personally I do not roast a pound at a time because it will normally  
last too long at my home and I like more variety available. But I am  
the only one normally drinking my coffee unless we have company.  
Normally I roast 1/3 of greens per load unless I know there will be  
company.

I'm with you on that one Dave. I roast two cups by volume at a time, which 
gives me a good variety. I'd hate to get tired of anything.

5) From: Stephen Carey
I would probably never roast a pound just for me.  But, this was for 
an event.  I like to roast a half-pound on one day, then another 
half-pound on day 2 or 3 or the other roast.  It gives me choice and 
lets me see how roasts develop with time.

7) From: Alchemist John
There is no harm in pre-heating the oven.  I do it all the time.  The 
only 'concern' is that the system will not start if it gets over 220 
F.  My procedure is to pre-heat 90 seconds, load the beans, and 
go.  Hell, I have even been known to load the beans, start the roast 
on P1, stop it at 90 seconds, select the actual profile I want and 
start again.  I really don't consider it double roasting, or even 
really starting roasting.  It's my version of pre-heating.  Getting 
all that metal mass up to temp without wasting profile time and 
energy that could go into the beans.  By doing this I find my roast 
to roast reproducibility goes way up as the 'real' roasts are all 
starting at roughly the same temperature.  Even though the chamber is 
220 after 90 seconds, the beans are not.  Barely 100-120 F.  Warm basically.

Thanks for that, John. Little by little you are letting us in on how the
thing works. How about a schematic?

"...how the thing works. How about a schematic?"
The schematic likely does not include a functional block diagram of the MCU
or the digital controls. How about the -1 manuals for the Boeing 777
aircraft? You don't have a wheelbarrow big enough, yet the Captain probably
knows them by heart, better than the A&P mechanics.
Does it give you pause to fly without access to the flight manuals or a
current AIM?

If I owned a 777, I'd want the manual. Have the shop manual for my car,
truck & tractor because I maintain and repair them. I sure didn't mean to
confuse you, but I'm thinking that a coffee roaster is a far cry from any of
the above.
