Brian,
I have a Milwaukee HG that has similarly-described functionality.  See it
at:http://www.cpomilwaukee.com/specialty_tools_and_equipment/heat_guns/8988-80=.html
The air temperature stays constant regardless of air flow, including if the
air flow is restricted by, say, beans in my roaster.

"Can the heat gun maintain a steady output temperature even as airflow
[changes]?"
Probably, the HG can deliver 1200 F air at the minimum 7cfm air flow in =
70
F ambient air at sea level. That's actually a lot of heat (BTUH). How many
BTUH or kW? Go figure- it's a good thermo problem.
If it maintains the 1200 F at 17.5 cfm air flow, that's 2.5X the BTUH or=
 kW
at low flow. Wanna bet the HG power doesn't change very much and it can't
maintain 1200 F in the high flow state?
For the $144 price, I could get exactly 4.0 of the Wagner HT 1000 heat guns
from Homer's Despot. The stated temperatures are just advertising hoopla,
since the sensor has to be inside the HG. So the LCD won't change as you
move the HG with respect to the roasting beans, that is the operating mode.
Save your money for more green coffee. If you don't rest the heat gun
properly after operation, you risk overheating the LCD and destroying it.
Then you'll have a plain heat gun, like me.

Brian,
Further to my previous post, I have been using my (similar) Milwaukee HG for
about a month with a home-made roaster, and getting excellent results.  The
1100F max temp.  will hold at hi & lo fan settings, although there is no
need to go that high. I find that I start a roast at 600F, move up to 700F
at 5 minutes/300F bean temp., then move up to 780-800F in steps depending on
what I'm trying to do, then drop back to 600-700 at first crack, again,
depending on what I'm trying to do. I'm still learning.  The HG will run
continuously.  It remains cool in the non-heated controller sections after
back-to-back roasts and gives every impression that you could run it all
day.  There is no duty cycle stated or cautioned in the manual or on the
HG.  The (hi) fan speed is low, but sufficient to roast.  An advantage of
the (low) fan speed is that the unit is very quiet and you can hear every
crack..
Its pricey, but having control over the environment (input) air temp, and
control over the bean mass temp (digital thermometer with TC probe in the
roaster) allows complete flexibility in roasting.

Bill,
That is very interesting info. Please help me to understand if I am
reading your comments accurately: Are you saying that you now have a
Milwaukee heat gun that has attributes (such as electronic controls)
similar to you Ideal Heat Plus Elite?
I was interested in your "heat gun profiling", meaning the different
temps etc at various stages of the roast. I suspend my Master
Appliance 751b. It has lots of excess capacity, so I run it at the
coolest setting (louvers all the way open) and control the application
of heat to the beans by raising the heat gun farther away from the
beans or lowering it closer to the beans. I lower the HG to within
about 4 inches for two minutes, then raise it to maybe 8 inches or so
(I haven't ever measured... I will try to remember to do that, if for
nothing else out of idle curiosity) for about 6 or 8 minutes to raise
roast temps about 10 degrees a minute. Later, after lowering the HG to
raise the temps of the beans about 30 degrees per minute for a couple
minutes, I raise the gun to go back to an increase of 10 degrees per
minute, but I've noticed that I can't raise the HG as much at this
point as I did earlier in the roast to produce an increase of 10
degrees per minute. So, though I fly by guess and by golly, it looks
like our basic profiles are very similar.

Brian,
Yes, my Milwaukee HG has electronic temp control.. in use, you slide the
temperature control (rheostat) and the PID display shows the temp setting
you have selected.. after a 2-second pause, the display reverts to the
discharge air temp of the HG.. you watch the display while the air temp
rises to the setting you selected, and the temp stays there.. I've tested it
by partially blocking the air flow and the temp stays constant at the
setting I selected.. the web site on my first post has the product
description, and if you surf that site, can find the HG manual in a PDF
file..
I "graduated" to my new homemade roaster and HG, from my first roaster - a
modified corn popper (manual switch inserted in the heating element
circuit).. in both cases, I profile the roast by measuring the bean
temperature.. hence, I was able to transition my profiles over from one
roaster to another. I've studied posts on roasting profiles from this blog
to understand roasting principles.  I agree, from your response, that our
profiles are similar..
I'm controlling input air temperature by on/off-ing the heating elements
(either manually or by a PID), while you are controlling input air
temperature by the HG distance from the beans (HG heated air blending with
room air), and the settings on your HG.
Try running your HG just into the air, and hold a thermometer at set
distances from the HG.  You should find consistent temperatures at various
distances.  Mentally then, you will know that at say, 4 inches you are
directing say, 800F, and at say, 8 inches you are directing say, 600F, at
the beans.

7) From: Brian Kamnetz
Hi Bill,
Thanks for the very interesting details on your roasting set-up and process.
You mentioned that changing the distance from my heatgun to the
roasting beans mixes room air with the heated air from the heatgun.
For roasting in a room with stable temps, measuring temps varying
distances from the heatgun would yield useful data. Unfortunately in
this regard, I roast outside where the temps vary from 30s to close to
100. What works for me is to fly by the seat of my pants, with some
cues, such as color of the beans, how rapidly color changes progress,
and sometimes a temp indication from my IR thermometer. However, I
like gadgets and have been interested in a heatgun with added gadgets
since the first time you mentioned your Ideal Heat Elite Plus. I
seldom make quick decisions and much of the fun for me is in the
pre-purchase investigation, so unless I am confronted with a VERY good
deal, it will probably be a while before I get an advanced heat gun.
In the meantime, I thank you for your very interesting information.

Brian,
you are welcomed... BTW, I'm not the same "Bill" that owns the "Ideal" HG..

Bill,
Sorry for the confusion. I am not good at details, and thought the
other Bill had decided to get an advanced gizmo Master Appliance heat
gun in addition to his Ideal Elite Plus!
Thanks for the info on your Master. After one of your previous posts,
I googled it, and it sounds like a very interested tool!
