It is a nice looking machine. You may bring it to the farmer’s market and roast couple batches while waiting for customers. This show piece should attract many people.
However, if you buy decent green beans @ $6.5 per pound, with 15% weight loss, sell roasted @ $16 per pound, you will earn ~$15.5 per 1-kg load. Besides, you will need a power generator. It’s a big toy, a lot of fun, but not efficient. I may get a TJ-067 (or some other bigger boys) at home to do the major roasting job, and show off the Aillio in the market as small batches demos.
