Subject: Hottop announces new programmable roaster
Hottop announced today that their long-awaited (by me, anyway)
programmable coffee roaster, the KN-8828P, will be available soon. It
is based on the current models, but incorporates a completely new
control panel and a new main control board. The older machines will be
able to be upgraded with the two new boards. I will be receiving a
beta test upgrade kit in the next few weeks so details of actual
operation (times, levels of programmability, etc.) should be available
by the end of January or so (a guess on my part). Check the Hottop USA
website as all currently available details will be posted there, and
there is a picture of the control panel as well:

all of the fires have been from sheer stupidity, on my part. the
last one, was roasting a robusta bean, and it got too far into the
second crack; fire occured upon eject of beans, when the beans
hit fresh air, well after the fact of how-hot-can-we-get-it-fast mode.

without actually playing with the new unit, I would only suspect
that, all other things being the same, the roast profile could never
be made to be hotter/quicker than the present machine. That is
without a different heating element, of course the new main board
may have a lot to do with applying 15 Amps directly to the heating
element...

Personally I am satisfied with the heating hysteresis in my analog
(aka: older) machine just fine, but there is a bit of Tim The Tool Man
in me that wants to turn it up to 11 once in awhile.

I'm looking forward to hearing your results! C'mon down the road
a bit to Vallejo, and we'll get wired on the almighty bean together
sometime.

I have done the exact same thing with an old batch of Yemen Mocha that
was past its prime. My brain said that maybe we could roast the uchhh
out of it if it was dark enough. The coffee was so old that second was
barely noticeable and I achieved it, surpassed it, and suddenly the
smoke from the roaster (out the back) increased dramatically. I hit
eject and WHOOOMPH when they hit the air. All the damage was
superficial and just to the panel over the cooling tray.

They state that it can roast in as little as 10:30 I think. If that
can be achieved with 250 grams it would be a big step forward. Of
course there are too many variable to guess what that means, but we
shall see.

Maybe we should have an altie get together somewhere in the valley? I
might be headed out towards Monterrey soon, so you never know! You
just might regret the invite! ;-)

It's doable with the element on full time on 115v.

Not the best profile choice.

I looked at the webpage-- along with the new control panel, the main
board also
gets some upgrades. To me, the control panel looks mostly like bells &
whistles,
aka: something for everyone to go "ooooh" over.

As was discussed at the roast "experiment," but not in depth, was the
heating
hysteresis enough to dramatically heat more quickly (if required).
This might
be partially accomplished with a new control board, but would better be
done with
either a different heating element, or the use of two elements.

Outside of having a variac, I run my hottop pretty much standard "7"
with a plus or two.
And thanks for the bean temp. monitor mod, works like a charm.

One thing different they could do is to have less plastic-- I've caught
my current
unit on fire a few times, and the plastic tends to burn/warp (plastic
that's just a few
inches above the tray, where the beans eject).

ps: as a sidenote, our kitchen *still* isn't done, dammit! doubt it
will be ready before
Christmas. Still planning on posting picturesof it in alt.bin.coffee
when it's done

Whether or not they got the programming right, and whether or no it
allows real profiling or it is just more "B's and W's" remains to be
seen. With 8 "segments," each of which can be programmed for time,
temperature, and fan speed it would seem that, depending on the range
available, it might be good.. or maybe not. We shall see.

At first you state that you caught the machine on fire "a few times"
but you also ask for more heat and a faster hysterious to the heating
cycle. It points to the difficulty of designing such a machine. How do
you make it work hotter, faster and at the same time keep people from
burning up their machines or setting their homes on fire and the
filing law suits, while still keeping it at a price point that is
reasonable?

The above comments are rhetorical in nature, but it points towards the
reason that there are only three(?) "large" capacity home coffee
roasters on the ket- Alp, Gene, and Hottop. There are other reasons
as well, but I hope you see my point.

As soon as I get mine and get some testing done I will release results
as soon as I am able.

Cool, but for criminy sakes, tell them to lose the count down and give
us the elapsed roast time.

The only fly in the ointment is the temperature sensor as the stock
sensor is worthless at registering roast temperature. It's off by as
much as 70F vs the bean mass temperature and various user's sensors
plateau between 405 and 415, not quite useful for determining EOR.

Unless the new unit addresses this issue, and the 'upgrade' has a fix,
the programmability will be strictly for entertainment.

Having it do either as the user's chosen default would be nice.

It is definitely one of the things I will be testing as I have done
before, and graphing the results. With the iRoast2 I was able to
create programmed profiles that created the bean temperature profile I
wanted. Hopefully this will not be necessary with the Hottop, but we
shall see....

I do not know if the sensor has been moved in the newer units as I
have not seen one- my guess is no. it is an issue I have discussed
with them. The "upgrade" is just the control panel assembly (control
board and face) and the main motherboard inside the unit.
