I am looking for how other Hottop roasters deal with the chaff that gets into the beans.  I find that there is a fair amount of chaff that ends up in the beans of the Hottop, especially with larger roasts or beans that through off alot of chaff.  I have been spreading the beans out in the cooling pan and blowing on them to remove the chaff.  This is tedious and does not remove all of the chaff.  Do any readers have other solutions?  Thanks.

Whirl and twirl in a plastic collander.

I am actually surprised the Hottop removes chaff as well as it does, considering the slow tumbling action.  But compared to an i-Roast, it definitely does leave more chaff behind.   That is why I put the beans in a collander after the cooling cycle and stir and toss them up a bit before storing.  It works especially well if you are outside on a windy day.  This is something I do not have to do with my i-Roast, but then I generally prefer the extra body the Hottop imparts.

I need to add that the above method will not work well if you roast really dark and oily.  I don't think you will have any luck removing excess chaff from oily beans.

I really don't worry about the chaff left behind in the beans.  I don't think there is enough chaff to affect the flavor of the coffee.

I use a metal (stainless) collander (helps cool the beans better than a plastic one for me), dump in the roasted beans from the cooling tray and I tilt the collander to about 30 or 40 degrees.  Then as above "whirl and twirl" in a "panning for gold" motion.  Most of the chaff seems to filter out through the holes in the sides and bottom of the collander.  For the remainder of the chaff, gently blowing on the beans while twirling seems to get essentially all of of the remaining chaff.  You can also roll the beans through your hands (like you do when mixing/blending green beans) and this seems to work chaff out through the collander holes as well.  It sounds like a big production here per my description, but it only takes a minute or two to do.  Oh BTW, it's probably obvious but do this outside rather than in your kitchen as the chaff seems to go everywhere...
