(also see Daily Coffee News feature ) Tije designed and made the following structure for a tiny and cheap fluid bed roaster, to which Jan van der Weel added the Arduino parts, electronics and programming: Sketch by Tije de Jong Jan sourced a very cheap blower (€ 11) to start with, Tije developed and constructed the mechanics, Jan built together and programmed the TC4 / SSR electronics. On his blog, Jan will specify exactly how the TC4 part is combined and programmed and I will copy these details into this blog entry, just as Jan will use this video in his blog. We did a few test roasts to make sure it works at all and it does. Towards the end, the first roast tended to get a flat BT line and airflow was slightly decreased. 200g seems max load of green beans. Second roast a little more power was given to the heater. Next we will try the Background Roast driven by the PID software of Artisan. A week later, with updated software that works better to change the fan

I wonder if you could take a look at this short clip and see what jumps out at you? Maybe my funnel is too shallow.

Anyway you can share the specs on the blower you have? There are like 5,6 different power and pressure levels that one can buy.
Cheers!

1) not too loud
2) delivering 20mBar or more
3) about 60m3 / hour
I wrote another response but somehow didn't show up here. Completely agree with your input on having my own blog and share info.
Cheers!
Here's my blog. I haven't get to the blower part yet. Just trying to capture the process so far.
It is painfully slow right now ...
Again, your sharing has been enabling me to go on, one tiny step at a time. So thank you again.
