Coffee Roaster, I had been using a airpopper to roast coffee and got some friends excited enough to buy coffee from me. I started to get a small following and could not keep up with the airpopper and built myself after lots and lots of trial and error a fluid bed style roaster capable of roasting 7lbs of coffee in about 20 minutes. Its a great roaster and 10 years later I still use it a couple times a month. I only roast for myself and my office at the moment.
