Rayo, out to lunch today with misinformation. Even flat out wrong
The small length of time, seconds, needed to empty a commercial roaster into
an efficient cooling bin DOES NOT cause un-uniform roasts. Quite the
contrary. My USRC 3k routinely doing over max rated capacity rated 7.1 to
8lb batches can roast far more uniformly than my $2700 Computer Controlled
HotTop doing rated 1/2lb batches.
And wrong again, the beans are not held at a constant steady temperature
state during the roast but rather constantly increasing temperature state,
similar for the roast environment though not the same with some late roast
stages ET actually lower than BT.
I won't go further about not just heat but type of heat and type of heat
transfer and air-flow affecting roast quality but have bagging to do...

Ultimately the quest for Koffee Nirvana is a solitary path. To know I must
first not know. And in knowing know I know not. Each Personal enlightenment
found exploring the many divergent foot steps of Those who have gone before.
