That is the plastic one. I've been using it for light duty roasting setup.

Nope, been using weekly, works perfect. Actually, does get pretty hot, and the input has warped a tinny bit, but this thing has been going for a few months without any issues. I would think it depends on how many roasts you do in a row,and do you let the system cool between roasts, that's what I do.

Love my Kaldi, check out my bean cooler, works amazing.

No melting yet, has been working solid for now. I will upgrade to a cast version soon, but so far, working perfectly.

The inlet of mine warped more so I cut some off and inserted aluminum pipe as a surface to clamp the exhaust duct onto.


If the whole thing doesn't hold up, I already have a plan to make a cyclone chaff collector out of stainless steel kitchen gadgets. :idea:

Given that your exhaust fan motor is AC and needs to be above certain voltage and RPM, maybe a throttle valve like this one between outlet of roaster and inlet of chaff collector would allow fine tuning?

I'm about to pull the trigger on a Kaldi Fortis, but trying to figure out the best way to vent it. Love your setup and was wondering how it's working for you.

Any thoughts?

I'm not him but I do use the same cyclone collector for chaff and exhaust. It's still holding up. Following pictures are how I have mine set up. Blower fan came with DC motor (eBay) which I use 24VDC wall wart with PWM controller from Amazon which allows me to adjust fan speed from 60 rpm to 3000 rpm. Because of this adjustable range, I don't need a damper to control airspeed. The chaff collector is aluminum box from Amazon which I cut out the side for hinged door made out of 1/8" thick plastic panel.





Hope this helps.
