While you were sleeping I have been active in booting out some spammers along with the posts they tried to sneak past me

Eth Nat Yirg Idido roasted yesterday. I dropped some off at a friends coffee shop. In a few days he will brew it and tell me what he thinks. We believe my roasts are better than what we buy.

Is my math right?
kwrcst
So my inner drum is 8.5ā€ across and 6.5ā€ deep. Iā€™d roast volume in oz =cu.in/10, am I only getting 11.74oz in this thing?

Mill City 1kg roaster drum is 8.75 x 7.5 in. Also in the specs they show the batch size .2 - 1.5 kg

Volume will be dependent too on how your vanes and drum internals are constructed. More stuff inside, less beans.

8.5 dia. X 6.5 length = bean volume should be around 36.88 oz. Which I believe is ~1 kg

Translated to metric system...
21.6 cm dia * 16.5 cm len = 6 liters, that equates to 1 kg according to some sources, and my experience too.
Close to 20 cm dia * 20 cm len (8x8"), the drum size of some commercial 1 kg roasters.

So your 326 grams math is heavily under-evaluated ...
