WISSXOER iCosoni Coffee Bean cooler Electric Coffee Roasting Cooling Machine High Capacity 550G Double layer Collect Coffee Chaff (350g Black)

I really like this because it’s reassuring to know this will definitely end your roast rather quickly as the beans cool down in just over a minute. The chaff collection works well. I roast 8oz of green beans and once roasted it’s just the right amount for the cooling rack. I wouldn’t want to go much more than that. I’m really pleased with this. I hope it lasts.

So it cools the beans way faster than I'd expected and that's the main thing it's supposed to do. But what I didn't expect is how well this helps to separate the chaff and other "crumbs" from the beans. If I shake the beans around the top layer (as though I'm panning for gold) the non-bean debris falls through to the lower layer. That is an unexpected benefit and I love it!

It quickly cools the beans down and removes much of the chaff from the roast. It was a great purchase and make my roasting time much more efficient.

I recently got into roasting my own coffee and am doing a lot of smaller batches finding my way. This item came available to me via the Amazon Vine program so I decided to give it a try. It arrived promptly and was well packaged to protect it from damage. When I opened it, there was no documentation inside the box. At first I was mildly alarmed but that turned out to be of no concern. It's basically a fan, with an on-off switch on the cord, that sits on a flat surface and blows vertically with a couple of screens that resemble aluminum cake pans. I didn't need directions to figure it out. Take it out of the box and have it ready before you start roasting. Complete your roast and move your beans to the cooler. Flip on the switch and let it do its job. It will become more and more useful as I gain experience and begin doing bigger batches. I don't have any issues recommending this. I will update if I have any issues in the future
