Topic: Programmable Hottop (10 msgs / 335 lines)
1) From: gmiller2
I'm about ready for a forced retirement, New Process Gear will be 
under Magna's full control by September.  Since being a Chrysler 
employee I'm getting an early, 1.5 year, start on my retirement.
 
I'm going to be looking for a roaster that will be able to do over two 
pounds at a time, and do it right.  Looks like from the discussions 
here that the RK drum in a garage or separate shed will be the way to 
go in our snowy cold New York winters.
 
Are there any RK drum roasters anyplace around Central New York that I 
may be able visit and learn how to use the RK?  If over twenty miles, 
I'll drive a car and leave the MadHemi Ram at home, 8 to 10 miles per 
gallon tops.

OK, I'm guessing you changed your mind about which roaster you wanted =
after
you started writing the message, so maybe you should change the title so =
you
attract the right audience :-)

Oops, my bad.  I originally had the right info copied and forgot to 
paste it in this message.   Got sidetracked on another thought.
Here is was was supposed to be in it.
Doing a search on the new KN-8828, I found this.

I highly recommend the Programmable Hottop.  It is well designed, well 
build, the Hottop support is excellent, and most importantly, you the 
roasted beans from it satisfy or exceed the expectations!
Using it is not "trial and error", because all the roasted beans are 
good, just different depending on the profile.  For me, is "trial - 
notes - changes" process. I still do not know what changes to expect if, 
for example, I change the profile by changing the fan speed during one 
part of the roasting cycle, etc. 
I wish I know what is the best profile, for example, for the Jacu bird 
beans or the Puro Scuro blend or our favorite Monkey blend.   Do I like 
the present results?  Definitely yes.  Can I get even better result?  
Most likely, yes, but I just do not know what changes in the aroma or 
taste to expect by changing the profile -- the possible profile 
adjustments are almost limitless. I wish more people would buy the 
programmable and share their ideas and profiles.
If you enjoy coffee roasting, if you enjoy experimenting and adjusting 
... I am sure that you will love the Programmable Hottop.
It seems that many people on this list are retired and have time to 
experiment and enjoy.  I strongly suggest: "Go for the programmable 
Hottop and enjoy using it!"  And share your experiences, please!
We have one of the first 30 or so Hottop machines imported into the USA 
years ago, before Sweet Maria's started carry Hottops; that "early 
adopter" version did not have the "protective wire guards". I converted 
that old machine to the Programmable model using the upgrade kit.  I 
needed to replace the fan, as the old original fan did not want to run 
on the programmable "slower speeds".
I love the converted "programmable" Hottop version more than our old 
"original"  As I said, I highly recommend it!

by this comment do you mean the older model with the 100 dollar upgrade?

Bird,
I mean the old (about 2002) analog Hottop (before it got the protectivewire shrouds) with the KN-8828P upgrade kit.

You don't have to sell me on the quality of the Hottop.  I have been using 
one, upgraded to the digital panel, for about 1.5 years and have been 
generally pleased with the results and the durability of the hardware.  What 
I am trying to determine is if there is enough difference in the 
programmable unit to be worth the additional cost.  I know that is 
subjective and some will say yes and some will say no.  I know that it still 
uses a thermistor mounted on the back wall to sense temperature.  The 
thermistor is not nearly as accurate as a TC and the placement does not 
measure bean temperature or even the heat in the drum.  The heat of the back 
wall is related, however, and that may be "good enough."  I considered 
buying one of Jeffery's CCR Hottops, but I can't justify spending that much. 
I am sure that his control squeezes every drop of possible performance out 
of the Hottop, but it is still only capable of so much.  I think that his 
control system on a commercial power machine would be unbelievably good.  I 
started building my own computer system and got as far as building the I/O 
interface board for the computer, but have gotten no farther.  I still need 
to come up with a calibrated TC amplifier to give me temp feedback and write 
a program.  I can't motivate myself to learn a programming language for this 
one project.  I know how to write ladder logic and would have no problem 
doing that for a roaster, but would need be able to translate that into 
machine language.
Anyway, if the new Hottop is good enough, I probably don't need to re-invent 
the wheel.
I know that I really haven't asked a question.  I've just rambled on a bit. 
Please forgive that.  If anyone has similar concerns or would like to add to 
my ramblings, I would like to hear them.  Thanks.

mike, you probably do not need the new model if the old one works fine. you still need to monitor your roast so why spend the money.
keep what you have until it bites the dust.

Mike,
only you can decide if there is enough difference in the programmable 
unit to be worth the additional cost.
After reading your message (copied below), I am about 99% sure that you would
enjoy and love the programmable unit.  I would guess that the probability that
would decide it was worth the cost is more than 1/2.
Is it perfect? No. As you know,  it still uses a thermistor mounted on the back
wall to sense temperature. The possible adjustments to the profile are limited.
However, at least for me, the advantage of the improved programmability are
more important than its limitation. It will be a very long time for me to
feel really limited by its capabilities. By that time, or probably much sooner, 
Hottop will possibly offer another upgrade.
For me the important fact is that I think that I can get a better smelling
and better tasting beans from the programmable unit as compared to the older
unit and that I have a lot of fun trying to learn how to use its (limited)
capabilities. The programmable unit has more capabilities than I know how 
to exploit.
I, too, am interested in reading opinions of other people. Now I am
looking for more profile adjustment suggestions.

I agree. I am still experimenting but have noticed improvement in my roasts 
especially in my DP beans roasts. Don't know if I would spend the 1K for a 
new one or not. I would probably go to a RK drum. I do not own a gas grill. 
so the total cost would be about the same.Also, I can use a grill year round 
here. However, since I had the digital model the price of the upgrade was 
worth it to me. You just have to weigh all the variables that are unique to 
your situation and needs.
