I have a almost new Sonofresco Coffee Roaster. It roasts 1.2# green per batch. It is powered by Natural Gas and 110 power. I learned to roast with this machine and it does a very nice job. I have since purchased a larger roaster and must sell this one. This roaster is ideal for a coffee shop, resturant, or a home roaster wanting to produce excellent coffee. Please PM if you have interest in this roaster.
