Topic: Air roaster (4 msgs / 87 lines)
1) From: Michael Walls
Dan,
I have been looking!!! Do you know where I can find a
High temp hot reciculation blower that has some
presure to move beans? I melted my shop vac. (just
kidding).  I have seen a few but they where
$380-$1200.  
I  have an all metal roating chamber ready With a two
inch inlet and outlet with and an 1875 watt hair dryer
heating element in the supply tube. Right now it is
just not hot enough even when I add heat to the bottom
with a stove.  I am looking at all alternatives.  I
need to calculate heating requirement if I do not
recirculate the air.  I am looking at clother dryer
heater tubes. 240 volts 4000-5500 watts. They cost
less than $50.   I am not sure if they will be enough.

However, for people wanting to air-roast a pound using
120VAC at 20A 
you need to
be looking at recyling that heat by returning the
exhaust to the fan 
inlet. It's
done commercially and I see no reason you can't. I see
no reason to use 
heat
exchangers, either.  Dan

Yeah, if I don't turn down the fan on my P1 after 1st crack, with just 
enough air to move 1/2 lb, I have to run the heater to 1800. So not a 
surprise to me.

What was that link where that guy made a jet engine to cool his beer? 
Didn't he use an automotive turbocharger set up?  It seems small enough...
Hmmmm...

Assuming that was not a rhetorical rhequest:http://www.asciimation.co.nz/beer/I love the site because the guy who did it is *funny*.  If you just glanced
at the jet, go back and read the copy.  I gotta email him and tell him how
much I enjoyed it.
