"Easy to clean, operate, troubleshoot....you name it"

We are a small batch roaster in Birmingham, AL, roasting on an SF-6. I couldn’t ask for a better roaster to roast on. I have roasted on many other brands and with the San Fran, I know what I’m going to get out of this machine every single roast and that it is going to roast coffee as well as I could possibly roast it. Easy to clean, operate, troubleshoot....you name it. But it’s built like a tank. It’s American Made so I know parts and service will never be an issue. And if I ever need to upgrade in size, I know that it holds its value. Not that I ever plan on parting with it. I never plan to buy any other roaster now besides a San Fran.

"Great product and user friendly if you know the basics"

"I went from a 2.6 lb roaster to the San Fran 6 roaster. Very easily transitioned and dialing in gas pressure and timing of the various stages of roasting. Great product and user friendly if you know the basics. Working on sealing out the smoke leaks. Should have a seperate cooling fan in order to jump right into the next roasting cycle and maximize the roasting lbs per hour. Currently 3 roasts per cycle with a 4 to 5 min bean cooling time per roast. Could potentially hit 3.5 to 4 roasts per hour with seperate cooling! On a 8 hour roasting day that could be up to 40lbs per shift and 200 lbs per week.  Just my thoughts. 29:11 Roasting Company!."
