I love my FreshRoast SR800, and enjoyed the machine even more when I added an Expansion Tube. Once I did this, I quickly found out that the stock chaff collection in the top wasn’t quite up to the job.
Also works with the SR540 Model
For a while I did a DIY solution which involved fine mesh wire, however it was always a pain to get it just right, was sharp and more effort than it was worth.
I searched for many solutions finally coming up with my own.
There is no assembly or cutting required. Simple snap/press the parts in place and start roasting.
The middle bean/chaff separator helps prevent beens from entering the chaff reservoir. It’s not perfect, and some beans will get by, but it greatly helps with the expansion of the side walls.
There is an option to add a 4mm or smaller temp probe. I used the following Thermocouple in the photos. – https://www.amazon.com/dp/B0D95HQNQP?ref=fed_asin_title&th=1
The FreshRoast OEM Top or Probe are not included. It’s only in the photos/video as an example of fitment.
This is printed out of a very high temp engineering grade nylon to withstand the extreme heat generated while roasting.

I’m really pleased with this addition to my SR800 with extension chamber. It definitely improved the air flow, and it allowed the air pressure to escape during the cooling period without blowing the top off. For beans that produce a lot of chaff, I use it without the center plug, so that less of the material plugs the center of the chaff chamber…more goes into the actual chaff collector. High quality item here!
The fit was not great and allows chaff to escape.
Great product and addition to my roaster. Easily installed. Roasted several batches and the material used held up beautifully to temperatures exceeding 400F . Highly recommended. Great job Greg.
