Flasherly,
When you say it would be nice to have on a heat gun or keep an extra
fan
for cooling. My wifes hair dryer with a cool shot button comes to
mind.
I'm not sure how to adapt it but being a higher end unit it has the
wind output. In this application you would have no use for the heating
elements.

Hi- low- setting on the heatgun only, no cooling. Add both guns to
the roast toolworks, hair dryer / heatgun off the same electrical
outlet. Drop and turn off the heatgun when the beans are worked just
right, and grab up the hairgun at fan only to prevent any residual
heat changing the roast from where you've got it.

I cycle down into air only and cool mine for a minute or so. I don't
want to mix hot beans straight into the colander with the last batch
of warm beans. They're too hot.

Here's the way I roast my beans.

I use a colander with some small holes instead of a dog bowl. I have a
cooler from an electromotor that I place on its side to blow air over my
roasting process. In the beginning it blows away the chaff. Later it
removes the smoke and cools the beans somewhat in the exothermic phase. I
start the roast on setting 1 and when the beans go yellow I go to setting
2. Between 1st and 2nd crack I go back to setting 1. When the beans are
done I place the cooler (in fact a pipe with a ventilator) upward and place
my colander in the pipe for cooling (it sucks the heat out of the beans).
This way I get a good result.

The best thing I have come up with is the "stirring whisk" that I attached
to the heat gun. I just destroyed a whisk and tied 3 of the wires to the
mouth of my heat gun.

I will post some picture of my "equipment" to alt.binaries.coffee.

Greetings,

JW
