Roasting - How To do it / Re: Mill City Roasting series - YouTube

Yes I agree the delivery of the content is a bit dry. Once I adjusted for it I found  the content useful and interesting .

Completely contrasting styles to Chris bacca and his crew that's for sure!

What did you think of the millcity vids?

I stumbled across a few more vids on YouTube  for those interested. This time from  "Wolff college of coffee". A lot more simplistic and basic but still an interesting watch ( a lot shorter vids on a range of bean/roasting topics ). Again more a simple educational resource than anything else.

I haven't watched much of the Mill City stuff yet. I've watched some of their short videos, but none of the Roaster School ones in full. I will at some stage, especially as I'd like to use a North roaster, but I'm in no rush. They're a bit hard to watch sometimes as they drag on a bit. Both Joe and Dave don't have a lot of energy and personality. It's funny, I hate to generalise, but I'm going to anyway. Americans seem to fall into two basic camps as far as personality goes - loud, bubbly, excitable, full of energy OR...... deadpan. Apologies to any US based members, I'm only half serious. ;-P

As far as the info and content goes I can't really make a full comment, but the parts I've watched seem to be pretty good. The general stuff is along the lines of current accepted practice. The machine specific stuff really relates to their roasters, but is still somewhat useful in a general sense.

Accessories / Re: Transparent portafilters

It is a diagnostic tool, like a naked portafilter. You would be able to watch the water make contact with the puck, and the subsequent expansion of said coffee.

Roasters - Different Roasting Equipment / Re: Rocquette Roaster Build

Hmmm i recognise that handle! I use Roast Logger software, a BT thermocouple, and a variac on the fan and adjustable regulator and gauge on the gas.

Yep, I'm still alive and kicking. Been a while though since I been on here. Still roasting away and mostly drinking good coffee from the Caravel. As I work nights now, I am occasionally in a situation where I have to drink caffeine beverages that are almost completely unlike coffee. C'est la vie.


Its all manual control at the moment, to convert a gas fluid bed roaster to run on a PID is a pretty expensive and complex project - and I am not convinced its bang for buck. I do use the Arduino TC4 to run the TC to the Roast Logger app, so its possible to hook everything up - the gas controller is the expensive bit, about $350 or so, plus some other bits and pieces to drive it via the TC4.

Plenty of options for monitoring without implementing auto control. Just understanding how previous roasts went based on what you changed manually can be a big help. I used to monitor and record quite a bit (Bourbon on an Arduino/TC4), nowadays roasting is pretty much repeating what I did before with minor tweaks.  If I ever do make a bigger roaster, it will be back to learning again.

I imagine airflow changes, even with a stable rate of rise would make quite a difference in a fluid bed.  You should be able to put monitoring on the fan quite easily if you feel like it. It will be most interesting to see how your project goes now it is actually roasting.

I'm curious if you are using any monitoring hardware/software?

I assume you have some thermocouples, possibly airflow/gasflow metering.

Always been fascinated by fluid bed roasters, probably because (like many) I started with the most basic one.

anyone got a link to the vids in question ?

Here's a link to episode one of the Roaster School videos. If it doesn't work just search 'Mill City Roasters' on YouTube. They have other clips loaded on their page as well.
