I read all of the posts today and especially looked at this one:
"At that price and with all of the other concerns, it seems like there
would be better options. Has anyone looked at the Amazon DL-A721-S?
I just saw it mentioned by someone on Reddit.http://www.alibaba.com/product-gs/651926781/Electric_Coffee_Roaster_DL_A721_S_.html
The good news is that it is 220v. The bad news is that the heater is
only 1200w. I designed and built the computer controlled roaster out
of modified hottops. I specially ordered some higher power heaters
(880w) from the manufacturer in Taiwan. That helped but still the
hottop could not do a fast roast. Those heaters are no longer
available and I do not have any more.
The Amazon looks like the Dietrich IR. I wonder if the Chinese copied
the Dietrich or if Dietrich buys theirs from China? Regardless, I do
not think highly of using an electric heater for large batches. By
physical limitations, they cannot heat and cool quickly enough to do
a good profile.
Regarding using a heatgun to supplement an underpowered home drum
roaster, I had one CCR customer try that to get roasts as short as an
air roaster. He caused the hottop to catch on fire and melt.
