Yes, that's what I tried to say. I mis-spelled the word produce. Oops. Turning the fan down, as the beans get lighter, has the same effect. My wife likes cooling them in the strainers. I ain't gonna argue with that one.
@pabbananna - The oil lamp shade does narrow down the air escaping a bit, and could, in effect, procude more heat in the chamber. I like the glass to look through, to check out the roast. I live up 'North', so, the outside temps can be in the 30's (like last weekend) or even down to the teens. I crank down the fan speed part way into the roast, to keep up roasting chamber temps. As the beans get lighter, the air can be turned down, in the winter. The "Ove-glove" helps keep from burning hands.
the lamp chimney slightly restricts airflow, and less air flow increases the heat, not decreases.... air is a better heat insulator than a conductor... convection cooling must keep air moving to grab more heat... heat being the motion of molecules and atoms means the more of them you have contacting the hot stuff, the quicker it will cool down.... prove it by holding your hand over a hot pan then touch the pan... conversely, dump the beans into a room temperature iron pan for faster cooling
I love homemade coffee, but my machine lay dormant until coffeeloverstipsandtricks (.) com plugged me in!

nice hurricane glass mod. I wonder if it helps make the roast more even? I've got to get me some of those nomex gloves too.
