Can someone help me for using forced propane burner as my heating element. I rather want to use lpg than electric. Do you think it would work

average cool down times you experience
jlhuge
Being a Popper I roaster I have a very manual cool down process for my coffee; dump into old mesh strainer, shake over exhaust vent of my shop-vac to increase air-flow over beans. Using this method I average about a 1 minute cool down in the winter and no more than 2 minutes in the height of summer. No smoke regulation means I'm banished to the garage so ambient temps are very weather and season dependent.

Now when I first started roasting a couple years ago, I read/was told that speedy cool down is important to stop the roasting process, much like shocking vegetables after blanching.

So in looking at various roaster models I'm seeing cool down periods in the 5-10 minute range, which seems awfully long, even with the larger batch size.

So I thought I would ask what your experiences are with cool-down periods after roasting

I've always been a fan of rapid cooling. Cooling is part of the heat profile and I want the roasting to stop when I want it to, not what my fan decides. Both of my coolers are high volume flow with only 1-2 bean depth across the screen, making a 1 minute cooling.
1 pound electric sample roaster, 3 pound direct-flame roaster, both handmade; modified Mazzer Mini grinder, LaSpaziale Vivaldi II automatic espresso machine. When the electricity goes out I make vacpot coffee from beans ground on my Zassenhaus hand grinder, and heat the water with a teakettle on the gas range.

What's the bean surface temperature you target for cooling?

No oil on my beans...

I am with Dan cool them as fast as possible, if its longer than 3 min I would really worry.

warm to the touch, but not hot.
I don't have a good surface thermometer so I can't say exact temp, but I would wager around 80-100 is where I usually stop.
