first time roasting coffee ever. i've been waiting a long time for the motor and it finally came.
equipment: rotisserie drum (amazon), tritogenia variable speed motor, thermometer gun.
beans: ethiopia sidamo
goal: medium roast to 210-215c (bean temp).
what happened: motor speed was 55 rpm (max). dome temp 350-380f. after 20 min, still looked greenish. upped temp to 400-420 dome. finished roast in about 38 min. longer than i had anticipated. 250g in. 210g out. 40 grams of chaff and moisture loss? color looks pretty uniform. i was happy with the result, but i have no idea how it's going to taste. i did not hear any cracking. maybe it was the thick walls of the kk, but i put my ear against the exhaust and heard nothing..
i was told i need to degass for a few days, even over a week if i want to run it through my espresso machine.
does anyone know how to upload video? i can't seem to do it on this forum..
