Wow, that's incredibly clever. Edward, you have amazing ideas!
Edward, can you elaborate on how this works? Looks cool though.
I grabbed a free standing air conditioner unit a year or so ago for doing just this - waiting for hubby to produce the interface for it.
It's just a kitchen aid mixer with a panning bowl--they are commonly available.
What I have is a portable air conditioner, made a "mask" for it, and stuck on a length of flexible dryer vent hose.
With this set up, I can direct a steady blast of cool air into the panning bowl. This greatly cuts down on the time needed to pan items. I can let this set up run unattended for 5-1o minutes while I do other tasks, run back, squirt in a shot of couverture, go back to other tasks and repeat.
