i think can be done leh, must buy those copper barrel.
I was in italy, i saw the fellow in the cafe pour the greens inside this small barrel and it automatic roll.
Two alarms, one alarm to roast.
Then the guy pour the roasted coffee out to cool. Another alarm will sound out when it's ready to be used and people start rushing to the counter.
I see the people all waiting there like ordering Koi.
The problem was, a lot of smoke, i think that's why they banned roasting in SG.
There should be smaller versions
Ya have...
actually for the price of a entry level espresso grinder like the rancilio rocky to mazzer you can have a home roaster:
