Share 'Roasting Beans with a coffee roaster'

Hi Chocolate friends! we just got a new roaster (for coffee) to be able to roast more beans. I'm starting my testings as it is much different than roasting in a convection oven. Any ideas, suggestion or tricks? The roaster is a 15kg/hour roaster, gas operating with variable drum speed.  any help or comment is great!   Thanks Nino
