Does tumbling the beans with steel balls break them up? I'd expect to find
beans broken & crushed.

Lubos,
I will leave the discussion of your "crazy" solution to others, mainly
because I don't buy into the problem. Relating directly to the the question
of whether the hottop has enough power to create a hard bean initial
profile, IMO the answer is yes, even for the nonprogrammable model!
In my simple view there are two things to look at: the temperature of the
machine and the temperature of the beans. My hottop, when empty, starts its
cycle at 163 degrees and winds its way up to top temperature in about 15
minutes, then exhibits a drop in temperature over the next 5 or so minutes.
Presumably that is a reflection of the built-in profile. Now the beans
always start at room temperature and follow the machine profile to wind up
at final roast temperature in about 18 minutes.
Now if I throw the beans in at the 163 degree start temperature, that will
produce a slow and steady rise to machine temperature and beyond. But if I
throw the beans in after 4 or 5 minutes, the machine temperature is then at
320 to 330 degrees and the beans will undergo a much quicker rise from room
temperature to machine temperature. If not the hard bean profile, at least a
step in the right direction. Now if I could get that initial temperature
even higher, I could probably create any initial ramp profile I wanted
(within the ability of the beans to absorb heat). We can't do that now, but
hopefully that's the kind of thing the programmable hottop will allow us to
achieve.
You can bet your balls on it.
