Topic: Fried Heat Gun (10 msgs / 173 lines)
1) From: Branden Byers
The roasting setup I that have been using for the past couple of
months is a slightly modified bread machine for agitation along with a
heat gun for heat. This morning I was all set up for a good roast and
as soon as I turned on the heat gun to preheat the bread machine the
heat gun cracked, popped, and died. I'm returning the heat gun as it
is under warranty at the hardware store it was purchased from.
Is there a modification to my technique that may assist in providing a
longer life for my next heat gun? Of course, I understand I may want
to eventually upgrade my heat gun as I am using a less expensive model
(the hardware store's own product line).  I point the gun at a slight
angle to the bowl as to help relieve the amount of heat that
recirculates back up towards the gun. Besides an upgrade (since I will
be getting this same inexpensive product as an exchange), what else
can I do differently? Or is two months an average lifespan for a
heatgun used for 2 to 4 batches (I usually do two 1/2 lb batches in
one sitting) a week?
Thanks in advance!

I don't know whether it actually helps or not, but my heatgun cold air
intake is only on the left side, so I hold the heat gun in my left
hand and stir with my right, and tilt the heat gun left so that it is
less apt to suck chaff and hot air into the cold air intake.

I have been roasting 2 to 4 approx. 10-minute length batches per week,
usually back to back, with the same $30 "Wagner 1000" heat gun for two
years.  Well, I guess there was about 6 mos. a year ago where I
roasted in the RK drum, so make it 18 mos.

When you shut it down do you let it cool first?
Turn off the heat, but keep the fan going. Wait for it to cool down. Then
shut down completely.

My wagner has a cool-downcycle.  Worth every penny....

Thanks for the quick responses! As for the cool down, mine doesn't
have that option. Would using an external fan blowing at the unplugged
heatgun produce a similiar effect (like cooling roasted beans)?
Does the Wagner 1000 mentioned by Justin have this cool down feature?
And as for the cool air intake, my heat gun has one on both sides.
Since Brian's only has a one sided intake, would it be a bad idea to
seal one side of intake holes with electrical tape?
Thanks again,

That'd make the gun run hotter. Many heat guns have an adjustable vent for
temperature control. Close the intakes to increase heat, open to reduce.

Principle: If you can turn off the heat element while air blows
through, you'll make the element last longer...
How you do it?  I dunno, I bought the one that has selectable heat
temp and a cool-down cycle...

My cheap, one-temp, one-speed Wagner (about $25 at WalMart) has lasted for
about 2 years.  I've used it less in recent months as I now also have a
HotTop, but for a year or so, I was doing 2-3 one cup batches per week.  I
usually roasted back-to-back, so the heat gun was running pretty much
constantly for 30-45 minutes.
If any chaff flew onto the intake vents on the side of the gun, I just used
my wooden stirring spoon to push it away.  Between batches, I brushed off
any remaining chaff.  I've never had a problem with that heat gun.
For cooling, I just pour the beans into a cast iron skillet or onto a cast
iron griddle, but now that we have a kitchen with granite counters, those
would work well too as a heat sink.

They typically use these heat guns for paint and floor tile adhesive
removal. This kind of use might take several hours of heating and scraping
with a putty knife or chisel.
I doubt if the Glorious Orange heat gun with switch and three prong plug for
$9.99 would last long in that kind of normal use. Mine lasted for two
months' roasting use, then the heater/ ballast wires fell apart and fell
into each other. This put line power directly on the bridge rectifier
feeding the motor.
Ring of blue fire around the motor commutator! Did it ever accelerate. Whee!
But the roast was done. Except for the chaff it ate, I was certainly not
abusing Glorious Orange.
Maybe I'll fix it and eBay it...
