Coffee Roasting by Weight Loss in Real Time (Air Popcorn Popper)

This is a bit goofy but thought I would share it anyway ...Playing around with an air popcorn popper and coffee roasting some gadgets, I realized that my lightweight popcorn popper can fit on a gram scale. So how about taring out the whole "roaster" and try to do a roast using coffee weight loss, in real time. Example ... can I decide to roast to 13% weight loss, watch the green coffee lose weight to that point as I roast it ... and stop the roast when I hit that 13% weight loss figure? This was more of an ad hoc experiment to see if it's viable using low cost stuff I have laying around. It also features a peek at my new project, which is a sleeve that fits in a specific air popper type and turns it into a very effective air coffee roaster for 120 gram batches. NOTE: What I fail to mention in this video ... is that I only achieved 9% weight loss! I mention targeting 13% but since I started with 110 grams I have to do a little math to get weight loss as a %. If I lost 10 grams, so my roasted batch weighed 100 grams, thats only 9% weight loss. (Quick weight loss formula refresher: Subtract the post-roast batch weight from the pre-roast green weight. Divide that number by the pre-roast green weight. To make it a % multiply by 100.
