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 & Older SR700 Models
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.

Did 3 roasts yesterday with it and the SR800 with extension tube and chaff extender. The chaff extender dramatically increases air flow through the unit. This is good but you have to increase heat to make up for it.
Without the extender I would end up at 6 fan and 6 heat. With extender 6 fan and 8 heat (I use a thermocouple)
Without the extender the sr800 would clog quickly. No clogging with the extender.
I’m guessing it’s 3d printed but the materials seem very good!
It doesn’t make chaff emptying any different. But you have to remember to put the center baffle back in.
Can I say wow after a couple of roasts? I still might want a better roaster but after a year roasting with the SR800 I can honestly say I never perfected it and I’ve tried.
What I found with this extension is more control of the roast. The extension allows so much airflow that it seems more forgiving, it felt like moving from a ‘toaster oven’ to an ‘oven’, this allows a fine tuning so each temp you try to reach is more stable. It’s like a scale that measures to the 1/10 and now it’s to the 1/100. I could be blowing this out of proportion, I’ve only made a couple of roasts time will tell.
But if my first impression is correct this 40 dollar product just turned my roaster into a small little commercial power house, without needing a program like Artisan to achieve a great roast.
My recommendation is, for 40 dollars get it, don’t hesitate. If I’m wrong it’s such a small investment that you can’t afford not to try it.
I almost never give reviews that’s how impressed I am and I don’t know the company and haven’t been paid to give a review.
I’m making this review the same day of my first roast, I’ll know in a few days if the development of the roast is better but anyone whose really used the Fresh Roast knows it’s not an easy machine to perfect, I think this product can really help…Thumbs up Leafgreen I think Fresh Roast should look into your extension and perfect it by making it part of their machine
Super awesome addition. I was using a cheap mesh extender that was a freaking mess. This is perfect. I can rip several roasts back to back without needing to dump the chaff. Thank you!
I can’t believe how well it fits together. It snaps together I can pick the whole thing up from the top after it snapped together. I also have the Razzo! The Razzo just sits together. I honestly didn’t think I would like the 3-D printed but it’s definitely nice. I refuse to drill my top with the Razzo chamber. I was putting the heat probes in through the seams of the stainless steel mesh. This has plugs with holes already included! That’s genius. I love it. If you have a Fresh Roast, you need the extended chaff collector! I have 2 of the SR800 and 1 of the SR540 I don’t even recommend the Razzo chamber. Honestly, I think you’re better off buying two extension tubes from fresh roast. If you have the 800!! If you have the 540 you only need one extension tube. You definitely need the extended chaff collector
This has worked almost perfectly but I think the center ring could use some tweaking as it clogs with chaff on some roasts.
