Topic: Fresh Roast Plus 8 Roasting Much too Fast (15 msgs / 551 lines)
1) From: Jon Rosen
I just bought a Fresh Roast because my iRoast is too noisy and often  
triggers the smoke alarm. I followed SM's recommendations carefully. I  
even weighed the recommended 2.25 oz of beans before giving them a 6  
minute roast. At the end of 6 minutes I had a French roast, not the  
expected City+. So, what's the story with the Fresh Roast? I want to  
control my roasts but this thing is way too fast. Is it defective? I  
also find it does a poor job in removing chaff. I only roast for  
myself, so a small capacity roaster like the Fresh Roast is ideal for  
my typical requirements, so I'd like to make it work.
Thanks,
Jon

Jon,
Here's a plan...  Cut your initial bean mass to 1.75-2.0 oz.  This
should slow it down quite a bit - start with the 1.75oz, and see how
you do.  Even if this seems counter intuitive, you may well be
surprised.  The larger the bean mass, the greater the heat retention.
By reducing the size of the bean mass, you are effectively reducing
its ability to retain heat.  You need to learn what the effective size
of bean mass is to accomplish your roasting goals.  Once you get the
"right" size for your setup, then you can start managing profiles...
Best wishes,
Brett

I read on this list that there is a way to adjust the fan speed.  I
have 2 FR8s and one roasts much faster than the other.  I believe on
one the fan is stronger and it usually takes about 5 minutes to the
1st crack.
Good luck,
Larry S.

OK- I have a refurbished standard Fresh Roast.
If I don't exercise some control over it, it's fairly fast too. With my
Fresh Roast, I learned that I would have roast completion at 6 minutes, if I
just wound it up and let 'er rip.
The Fresh Roast is a neat little teaching machine, besides, I live to
tinker. The blower runs continuously until the timer shuts off at the end of
the 2min cooling cycle.
An adequate (14ga wire) extension cord will drop enough of the voltage to
the roaster to slow it down. It will both reduce the heat exponentially (V
squared) and slow the blower linearly with the voltage drop. It will keep
roasting, but the heat will drop faster than the blower speed.
Your 100 foot weed whacker extension cord is overkill and a poor choice.
Roaster is a continuous electric load, while the weed trimmer is
intermittent. If you leave it conveniently coiled up while roasting, the
extension cord will become quite hot.
Both the heater and the blower run in the roast cycle on your FR+8, from 8
minutes max to the end of timed roasting. Then the heater shuts off and the
blower continues for 2 more minutes to cool down.
If you baby-sit the thing, you can obviously stretch the full power roasting
cycle to as much time you want.
If you want to reduce the heat of roasting, you can just start roasting and
advance the timer intermittently to the Cool cycle, i.e. 5s. of every 30s,
or 10sec of 60s. Then you'll have to use some other clock for roast time.

I also have 2 FR8s and one roasts faster than the other.  When I first
started roasting the FR8 was perfect for me, but my coffee consumption has
increased to the point where I now use a HG/DB method. With one roaster, I
would  reach first crack at 4 minutes, the other would reach 1st crack at 3
minutes.

This is a multi-part message in MIME format.
My FR8+ has an odd timer on it. I now use a stop watch for more accurate 
logs. The "8" minute timer on my FR8 lasted 6 minutes to the cooling 
cycle. Of course, all things being relative, the timer only means 
something to that machine and your logs would reflect that.
So it might not be as fast as you think it is... or it could be faster 
than you think it is...

I also have the FR8+ and find that the time will sometimes depend on  
the bean being roasted...some get to first crack in 4 mins some in 6.  
I roast in my kitchen and find that if the window is open so cool  
area comes in on the roaster, the roasting time will be prolonged.

My quick roasts with the FR8 comes from altitude, but all of my roasts
last between 2.5-3.5 minutes, that's all.  I guess I could have slowed
the fan down... But I never did.  And never seemed to have a problem
getting tasty tasty coffee.

Unless I missed it, no one has mentioned the variable resistor.
There is a variable power resistor in series with the fan.
Bringing the wired terminals closer together will speed up the fan (cooler
roast).

I lowered the batch size to 2.0 grams and that didn't make a  
difference. If I have to go to batches smaller than that, I'm not  
interested in using a Fresh Roast. Adjusting the fan's variable  
resistor is a possibility. I wonder if there's a simple variac that  
would go between the Fresh Roast and the wall that would lower its  
voltage. It would make it a lot easier to find the right setting.

You said the magic word - Variac.
Use the 2KVA Variac to control the heating element.
Remove the diodes & wiring to the fan.
Connect a variable 18Vdc supply to fan observing polarity.
This setup will roast ~3 oz greens to perfection.

This sounds like I would need to do my roasting on a laboratory bench.  
I don't want external power supplies and wiring on my kitchen counter  
attached to my roaster. Maybe simple external mod?

I made the adjustment to the coil that's on SM's Website. It has  
slowed the roast down a bit, but I'm not sure if it's enough or not.  
I'll try it like this for a few days.
