I have been an avid home roaster for about 20 years. One problem we face is chaff removal and fast cooling of the hot beans immediately after roast. I found a craftsman in Taiwan who makes table top coolers and chaff removers. It is a bit expensive with the shipping from Taiwan but well worth it if you are serious about roasting.

That looks amazing Barry.  How long does it take to cool at kilo of beans?  And how much chaff is left?

I end up putting my beans in mesh colander and blowing a fan on them, it helps remover chaff and cools the beans very quickly.  But, it's a pain in the butt, and it's messy.

Someday I'm going to up grade from my Behmor 1600+ to the roaster you have.

Shawn the apparatus is amazing. One kilo of beans cooled to room temp in 1 minute. All chaff removed in the same minute. Chaff has to be cleaned after 5 roasts. Takes no time with a shop vac

Very interesting. While I am not personally interested in home roasting, I do appreciate the ingenuity and usefulness of the product. Are you drinking the best coffee of your life?

That's awesome!  And so much less work than my method.

Very nice.  Do you spray a little water on after roasting to aid cooling and replace some of the weight lost in roasting?

Not necessary water used to replace water in bean evaporating as steam fast cooling eliminates this step and avoids bee being stored wet and inviting mold

Aha.  I own a coffee shop.  We use a bean supplier rather than roasting our own.  But am familiar with the roasting process.  I know some roasters do a water/air cool combo.  I was curious about your setup.  Happy roasting.
