I've been home roasting for a few months. I started with an Air Crazy, but fried it in a couple of weeks.

Like most, after getting a taste of what home roasted coffee tasted like, I wanted a larger capacity and built a Turbo Crazy. It works a dream and I've been getting nice, even controlled roasts. I'm currently working my way through 20# of La Minita.

I use an Aeropress at work (and sometimes at home) as well as a ROK (Presso) manual espresso machine, so I'm usually grinding pretty fine in my Baratza Preciso.

All is well until I grind coarser for the drip machine at work. I'm getting a light colored flake mixed in with the grinds. I have a chaff ejection ring on the SCTO, and have a separate vacuum driven cooling system that would draw any loose chaff out, so it's not chaff. I think its from the "parchment" in the seam of the roasted beens.

Any thoughts on what this is and how do I get rid of it?

I think it's the chaff stuck in the bean and I think you should just ignore it. If you're concerned try brewing a cup of only chaff and see if it has a flavor you should really worry about. I've always read to ignore it. I imagine its lighter than the actual ground coffee so you might be able to build a separator that uses a gently flow of air to blow the flakes away.

Yep, it looks like that what it is:

It just really looks like crap in the grinder. There's a lot of it.
