Roaster automation
I have a Primo PRI-21 roaster. The control panel has gone out on it and I am exploring options for automation. The roaster runs IR burners and a 2 stage gas valve. My though is that I should be able to find a 2 stage controller with an input for the bean probe and a usb or serial output. Any ideas for a source?

With the help of Omega Engineering I have put a new PID Control panel in my roaster. It has given us much greater control of our roast profiling and what we learned while roasting completely by hand for the last month is invaluable. We are very excited and really feel this is a big step up in quality and consistency. The best part is I did it for less than $400 in parts.

Hey Jason,
Did you explore being able to log your data (temp/time)? Perhaps you are not set up for this. I am also curious about adding this after-the-fact. I am assuming that you have to manually set the temp on the control box (thus not able to 'save' a temp profile)?

I will be installing a data logger from omega they have a few different ways to go, I will run the data logger off a second thermal probe and it will just be a secondary system. It should be about $600 in parts and they have a logger that you can access via wifi.

I'm interested in as detailed a breakdown of this system as you're willing to provide, Jason.

excellent suggestions so far, i emailed the links to the roaster and we'll see what he thinks. this is the stuff i really dig - i'm never going to be able to taste every coffee but having specific information about the coffees i do taste helps so mu…
I have worked in a shop that did this, and even if you grind the decaf and take it straight to the machine, you still can't dial it in to pull decent shots. It would be better to have a cheaper lower volume grinder to dedicate to decaf if you are wo…
Royal has a fair amount of info on their website for some of their coffees. They are also very helpful if you ask, they certainly know where their coffees come from. If you're looking for something smaller, I highly suggest http://www.coffeeshrub.co…
I personally use Big Train Spiced Chai at my shop and people love it. It is a powder. We mix it with milk and it's really delicious. If you are at all in or around the Bellingham/ Seattle area, my most favorite chai is Harmony Chai brewed by Holly D…
The whole pre-infusion thing is a little bit overrated imho. For instance on an E61 machine, you've already got pre-infusion by design. You're really not accomplishing a whole lot more by adding to it. Take for example the majority of La Spaziale Vi…
As I understand it, the contemporary school of thought is of the mind that your best bet is to use unrested beans; however, this will only buy you a very small window, beyond the ±30 minutes alloted for the espresso ground coffee to degas, where qua…
We're moving our coffee operation into a much smaller space, and I'm considering pre-grinding a small amount of decaf at the beginning of the day (maybe using the Bunn drip grinder set on "espresso") and keeping it in a small Cambro container by the…
I actually meant to post the above reply ^^ in the discussion entitled "Best commercial espresso machine", but I suppose it could be relevant here as well.
Still getting used to this forum's layout! :p
