Okay, the skinny: Blind Tiger Coffee is powered by a 1950’s/60’s 7.5 KG GW Barth roaster (and sandwiches with cured meats). It’s a great roaster and my affection for it and what I can do with it continues to grow all the ding dang time. That being said, I purchased a larger roaster (yer buddy has some modest plans…) and the time to say goodbye to my buddy Barth approachith.
About the Barth: It has a burner that is powered via natural gas and ONE MOTOR that uses 3 phase power. Happy to get more in the weeds about those details as needed. But like I was saying, it has one motor that controls all operations, including one fan. There’s a damper/door that controls air flow from the drum vs airflow from the cooling tray. Truthfully, I don’t feel like I’ve ever really needed two fans (though two fans is more than one and more is more). Further!, in my opinion, the way that the air system was designed makes for better, dare I say greater amounts of convection possible than roasters like Probat L5-12s and Diedrichs (and I’m not throwing shade at those machines, I like them too thank you very much) which have longer runs from the drum to the fan. Lastly, there’s an area under the cooling tray that is currently covered up by a sheet of metal and best I can tell be could be used to get another fan hooked up to. Thus double fan action is possible (methinks). So, if you’re handy or an engineer and you’d like more…
This roaster has 4 probes for Bean Temp, Environment, Exhaust, and inlet temp monitoring. These measurements are handy as “heck.”
Other things: I replaced the v belt last year and the chain to the drum this year. The motor’s bearings have been replaced too.
I clean this thing every week. It’s on (from warming up to cooling down) around 5-6 hours a pop 3 days a week.
There are some things that I’ve wanted to do for a while now, but who has the time. One such thing (well the main thing) is play with/replace the rear cog to see if I could get that barrel spinning a little faster. I might still do this? I’m crazy. But, then again, for all the fearless engineer types, you could always slap a few more motors with vfd’s on this thing and then you’d be truly invincible and the rulers of coffee roasting. But ya know, it seems like people like my coffee sometimes and perhaps these are ultimately unnecessary, typical musings of a cis white male Millenial swimming through an ocean of Youtube videos daring me to be a nerd and hyper customize all things/put every bell and every whistle on a thing.
The roaster comes with chaff can and the table it sits on (if you’d like). I also have some double walled exhaust ducting that we could talk about?
Lastly… maybe this means something…maybe it doesn’t. I bought it from the owner of Bonanza Coffee in Berlin, Kiduk Reus. While I haven’t kept up with him, there was a time where he was wheelin’ and dealin’ refurbished roasters (with the help of Brian Højmark Larsen). Which is to say, those guys refurbished this roaster. That was cool that they did that.
Anyway, I’m asking for $22,000. That doesn’t include shipping. I think that’s a pretty fair ask. I’d really like to keep this with in the US (for many practical reasons).
There are so many things to talk about with this sale and this roaster, so I think I’ll just end this weird sales pitch here. If you’re interested, if you have any questions, or if you’d like to make some kind of offer/pitch to me, please shoot me an email: blindtigercoffee@gmail.com
Thanks/best,
