[Homeroast] Hottop control

I have had my CCR Hottop for several years now and am extremely pleased with 
its performance and durability. If I did not already have one, I would jump 
on the chance to buy the one that Jeffrey is offering. As someone who has 
spent my life working in the electronics and engineering field, I can say 
with some authority that Jeffrey's design and constructions are excellent. I 
have worked on multi-million dollar machines with less care in their design. 
Jeffrey is a perfectionist and it shows in the CCR. He individually 
calibrates each one and adjusts its program for the individual variations in 
parts. My program would not work in your machine. I bought my CCR used and 
the previous owner used it to supply a coffee shop so it ran continuously. 
When I first got it, I replaced the heating element as all that use warped 
the old one. That is the only service I have done in 4+ years. All I have to 
do is blow out the chaff after each roast. (I remove the chaff tray and dump 
it; then blow air down the bean chute which blows the remaining chaff out 
the tray's slot.) I run about 7-10 loads in a row about once or twice a 
I have written lots of roast profiles, so if you buy it and need some to try 
out, contact me off-list and I will send some to try.

Thanks Jeffrey for the information!
That 1kg Probatino on your website looks exactly like what I envision 
upgrading to after I build a garage (after a deck, after a fence, etc.) I 
guess that
backyard shed you put yours in is sufficient for Southern California 
climate. I'm hopefully planning an insulated, temperature & humidity 
controlled roasting room for Maryland summers and winters.

I will contact you directly regarding the Hottop CCR.
Thanks again,

Answering your last question first,  HotTop never came out with their higher 
capacity model. They promised it for years but it never appeared.

I spent several years developing the computer controlled roaster (CCR) which 
was based on a highly modified HotTOp.  It works flawlessly. While doing 
extensive experimentation, I found that the airlow within the HotTop is not 
great.  I experimented with continuously variable fan speed and found that 
it is truly best to leave it at full speed all the time.

Although I stopped the manufacture of the CCR systems, there is one owner 
who has retired from drinking coffee owing to medical reasons. He is willing 
to sell his through me as I would need to do a full refurbish and 
re-calibration and then compile new software for it.
For a description, see computercontrolledroaster.com
