This was something miKe McKona posted 3 years ago. Being the computer
geek I am, I saved it. For those who appreciate technical humor, please
swallow your mouthful of coffee...
"Also, I just figured out my wife and I drink over 1/2 lb. of coffee a
day. Roasting in a Poppery II is starting to get old REAL fast! ;-) I
actually starting thinking I could run six Poppery II's and roast a
pound of coffee in under ten minutes. No, I wouldn't do that... but it
IS a thought.
Yep... a Poppery II Array!
"RACR - Redundant Array of Cheap Roasters"
By daffynition a RACR 5 six popper array would be 6 poppers with
databeans & pair-a-beans striped across all poppers, unless using one of
the poppers for a hot spare, then your usable batch load is reduced by
one popper. Single popper pair-a-bean would be RACR level 4, which is
never seen in real world roaster applications, since the single
pair-a-bean popper must work as hard as all the databean poppers
combined, it was just part of the original Berkeley popper papers:-) Of
course the FR speed roasters never use pair-a-beans, preferring the pure
striping fastest roasting RACR level 0, though it has no rebeandancy and
is therefore risky. Whereas a RACR 1 mirrored pair (of drums) aren't
nearly as fast but offer great rebeandancy.
And whatever happened the RACR level 3 anyway?
Not to mention the need to address RACR Controller ca$h policies.
Obviously Roast ahead is enabled regardless using a Controller with ca$h
DIMM battery or not (Double Insulated Massive (bean) Movement) but
wRoast back versus wRoast thru policy would be important consideration.
Roast ahead policy enabled so databeans can properly rest and you don't
run out. If you have battery backed up ca$h then wRoast back is safe,
meaning back to back batches is safe. But without battery backed up ca$h
wRoast thru should be the policy, meaning roaster thru cooling before
next databeans loaded. This is assuming with pair-o-beans rebeandancy.
Without pair-o-beans simple UPS will do (Unlimited Pour Supplied). And
should always use a surge protector. (Simple Under Roast Guard Enabled).
But the over riding ca$h policy is usually this: it goes to Sweet
Maria's for more databeans!"
