1> IICRC The beans are Costa Rica Hard from CCMCoffee in Tampa FL.

The brisk stirring of the paddle and the fluid heating blast from the heat gun, keep all batches uniform. I buy from SM and CCM.

2> I usually roast 1/2 pound at a time. I believe that it will roast 1 pound ore more. It takes less tha 10 minutes a week to keep me supplied with fresh roasted beans. It heats up in less than 1 minute and I can maintain temp to withing +- 10 * quite easily.

3> There is NO heat damage to the heat gun. Only 1/8" of the tip is exposed below the aluminum cover plate. If it ever wears out I have a spare Harbor Freight HG that I bought for $9.95 on sale down from $19.95.


I hope that others will try this method. I have no plans to improve or to mod this design.

(I am working on a really simple and effective bean cooler)
