Batch Size

Still very new to roasting!

I have a 6kg and was wondering what the smallest batch size you would recommend running through it? (Side not I am not interested for "Sample" size roasting as I know it can affect a lot of variables that do not benefit the coffee or the roaster)

Also will I need to adjust Fuel to it?

I design all of our roasters to operate optimally from 20% to 120% of capacity.

A smaller charge usually requires a lower preheat, lower gas setting, and lower drum speed.

If I were running a 1200g charge on the 6kg, I'd probably preheat to something like 350F, start with a 30-60 second soak, run the drum at around 40-45 RPM, and bring in my heat after soak at maybe 1 kpa.
