Topic: HotTop - Progress! (2 msgs / 106 lines)
1) From: Maryann & Dave Schellenberg
Thank you, Barry and Terry for your helpful comments.
Terry - my HotTop is about a year old, and yes, a + adds 30 seconds to 
time remaining.
Having previously manually monitored my Poppery roasts, I found roasting 
with a HotTop without recording and adjusting every minute to be very 
relaxing. But without the comparable feedback, I worry some. So today, 
before starting my roasts, I cleaned the window, removed the faceplate 
and drum, vacuumed, and bored holes in the bean chute cover for my 
temperature probe.
First I roasted Sweet Maria's Colombia WP Decaf. I set the HotTop to 21.00.
Here is the data:

I removed the chaff drawer, bean chute cover and filter during cooldown.
Then I roasted Sweet Maria's Indonesian Organic SWP Komodo Blend
Set HotTop to 21.00  Didn't seem to want to signal for beans, so I 
switched power off/on (coming from a variac).
After running a little more, it signalled for beans.

Comments:
The Komodo Blend is much darker (but no oil) in color than the 
Colombian, but I'm guessing that's a bean characteristic.
The second roast took longer for the probe temp to catch up with HotTop 
temp, which accounts for the extra two minutes it took to complete the 
roast to FC+
I now believe that the weather conditions on my previous roasting day 
were responsible for the light finish on those roasts; It was about the 
same temp as today, 80F, but very windy, while today is calm. Have you 
noticed wind affecting your HotTop roasts? Next time I need to roast, 
and it is windy, I'll do it in the garage.
Please respond with any comments you may have.

Looks like your figures are similar to mine and I am very pleased with the 
roasts.As to wind I don't know.I roast in a wind shielded spot on my lanai.
