I read somewhere that higher elevations have faster roast time and require somewhat lower temperatures. air is thin and has less Oxygen

Yes, 1st off, you must use only Panama Esmeralda Geisha beans and be sure to only roast on Saturdays. Actually, this isn't completely true. Please post in all about roasters forum. Thx!

I’m at 9,000 feet elevation, is there any special adjustments that need to be made to roast using an SR 540 at this elevation?

Coffee Roasting Has Begun!

If the degrees meaning is baseplate temperature, then is not enough, you need this temperature in the air.
These machines are designed for popcorn, that bloom at 180 C, while coffee need at least 250C air temperature, to bring the bean at 200-220C.
Contact transfer is ridiculous low, the main heat should come from convection, so you need an increased airflow.
If your lid is 32 cm diameter, then you can buy an extension ring as this...

The link is in UK, I know, was the first I found, is just an example what you need, there are similar rings in US too.

... then make a hole allowing to insert a hotgun, that will bring the necessary heat and airflow.
The air should be blown along the wall (tangential), not to the center.

As is now you have not enough heat transfer to perform a right roast.


Thanks for the information. I need this thing.
