1-6 lbs Roaster Build - Nothing Fancy
renatoa
There is an 1/6 rule of thumb, valid for almost all machines that roast using hot air.
1/6 should be read as 6 litres of roast chamber volume for 1 kg of greens.
An example is the typical dimensions in the 20x20 cm (8x8 in) ballpark, of the 1 kg machines drum.
Or 160 grams for one litre glass for a FB machine.

Actually, this rule is not so "of thumb"... it has a physical explanation, coming from an equation where you put heat capacity of air and coffee beans, and other constants... but nobody bothered so far to this level, just passed to the next, as coming from horse's mouth Grin
