Hi Jason, I watched your excellent review on this roaster and got my hands on the 150g model. As you said, it is a great roaster for roasting small batches and I found that it even have enough power to go beyond the 150g limit. The temp display is not accurate though but I use Mastech 6514 for temp measurement and connects it to Artisan on my laptop.

i use this machine for over 2 years, broke down 2x. The only problem is the power control board. Based on my analysis, it can last for about 70x of roasting, after that it starts deteoriating (power is dropping, so that you need to reduce the load, load means the coffee bean). When you see power is dropping, go replace the power control board (the board that connecting to the power knob). That's all you need.

Thank you for the kind words. The bean temp probe comes with the roaster. Regarding cooling, I recommend an external bean cooler, but you COULD just turn the heat off and let the loft fan continue to run, as other sample roasters also do. It wouldn’t cool the beans as quickly as a dedicated bean cooler, but I haven’t done tests to see if there’s a benefit in the cup to this approach.

For the batches from this video in the garage space, yes I just just cooled them directly in the roast chamber. I don't recall exactly now long it took to cool... it was ok, but certainly not as ideal as a separate cooler (because the heated mass of the RC itself slows down the cooling process).

Glad to hear you've caught the roasting bug! If you want to automate it using Phidgets, you'll want the RCC1000 and the TMP1101. I have videos on how to configure Artisan for these. The YoctoWatt is really cool, but also pricey compared to a standard ammeter. It has a max current rating of 16A, which is adequate for the Smola, but nothing larger. It really comes down to whether your REALLY want your electrical properties to show up in Artisan vs. just a digital screen on the roaster (i.e. a standard ammeter). I have the YoctoWatt, but it's difficult to justify the price unless you're going to use Artisan to actually do something with that data. (For instance, you might alter automated loft settings based on incoming line voltage). But if you just want to see what your line voltage is, a simple ammeter is many times cheaper. Good luck!

@@DIYcoffeeroast Yes, my thoughts on RTD vs. Thermocouple have certainly evolved. I still maintain that RTDs offer a more stable temperature reading, but much of my issue with thermocouples had to do with a noisy signal. Once I cleaned that up, the performance of the thermocouple was adequate enough to reliably use for PID. While I loved the accuracy of the RTD, I had 2 of them fail in under a year, and they're quite pricey. So at this time, given the price/accuracy/reliability equation, a clean thermocouple signal should be just fine. If you go the RTD route, I would suggest always having a spare on the shelf.

My update is an unfortunate one... my Smola roaster melted into oblivion. In the end it was user error, but also illustrates a design flaw. Yes, I was able to completely automate it by creating an adapter for a Hermetheus Roaster Co-Pilot (an automation device that we make for Coffee Crafters Artisan and Valenta roasters). The Co-Pilot replaces the heat knob on the roaster, so turning it by hand isn't possible anymore. After a roast finished, I turned off the loft to dump the beans, but the Co-Pilot robotics left the heat elements on. This was my fault. I should have turned the entire roaster power off. So while there was no loft running, the elements were still glowing red hot as I dumped and cooled my beans. That's when the fun molten metal drama started! The design flaw? Every coffee roaster should incorporate a high limit safety switch to protect against this kind of bone-headedness. The Smola lacks that. It's still a decent little roaster for the money. And yes, I was running it on 60hz/240v. I could still recommend it. From a strict "roast quality" standpoint, it's outstanding! From a design and ergonomic standpoint, it has some flaws. My biggest complaint is that the roast chamber lacks ANY kind of grip/handle to dump the beans. My best guess is that Smola intended for us to use the roast chamber as the bean cooling chamber, but I'm not a fan of that approach. The roast chamber retains so much heat from the mass of metal and glass, it makes for a very slow cooling process (which runs the risk of "baking" the beans). I crafted some cabinet handles on the roast to assist with dumping beans.

Hi, Ryan. My overall impression is still pretty positive. I'm STILL planning on doing a shorter video of how I've automated the heat control via servo and PID, which makes this a fantastic little automated "profiling" roaster. One of the shafts of my potentiometer knob cracked when I was a bit rough putting the servo on it... it's incredibly brittle pot metal, so that was annoying. Compared to the SR800, it's a far more capable machine, if for no other reason than sheer power. At 3kw, there isn't a 110v roaster that can compete with this on heating capacity. (But of course, 220v carries the huge disadvantage of convenience, so only you can decide which is the better tradeoff for your use.) I have zero regrets, and I would buy it again. In fact, I'm considering buying the 150g version or possibly even the 50g version (which is VERY cheap) to see about doing a possible 110v, PID-automated conversion that wouldn't break the budget!
@Leo-eb1wl Жыл бұрын
Generally speaking you can’t really set a profile from a sample roaster and have that translate on a larger roaster. Every roaster is different and every coffee roaster on any roaster will roast different and normally be roaster specific. Roasting a sample is all about imparting minimal roasting influence on the coffee, find out what the coffee has to offer and with that information you then formulate a plan on your larger roaster that will best accentuate the coffees qualities. I’ve been roasting for 15 years on anything from sample roasters up to 120kg roasters and I have never seen a profile from one roaster translate to another roaster.
@hermetheuscoffee Жыл бұрын
Thanks for your input, Leo. I certainly agree with you if we're talking about drum roasters. However, that's not my experience in comparing this roaster specifically to the Coffee Crafters fluid bed roasters. There are far fewer variables on fluid bed roasters of the same design (and both this Smola and the Coffee Crafters Artisan line are "spouted bed" designs). The cycle rate of the beans is nearly identical (the number of times per minute that each bean cycles through the heat) and the roast air temperature is nearly identical. Finally, add in automated PID control and I have found it to be remarkably comparable.

@hermetheuscoffee Жыл бұрын
Yes, for this video, the probe was connected via a Phidget. Since then, I've changed that, but it was more for size reasons than performance. The Phidgets are great. I unfortunately can't tell you if the nano is a better choice, because I don't own one. In the end, even when I do my video on the PID automation of this unit, I've come to the conclusion that for U.S. roasters, it's not really comparable to either the iKawa or the Nano 7. Simply because of the need for 240v on this unit. Don't get me wrong... for performance reasons, the 240v is AWESOME! There's heat power to spare, and profiling roasts is amazingly easy and predictable. But it's simply not portable. You could take an iKawa or Nano 7 on the road with you, but where would you find the 240v plugin? It's a real drawback from a convenience standpoint. Having said that, where this Smola roaster really shines is its ability to perfectly scale up to larger Coffee Crafters Artisan roasters. If you can nail a profile on the Smola, you can use that exact same profile on an Artisan and end up with the EXACT roast. So if you're not really concerned about portability AND you have 240v, this is still a fantastic sample roaster. I'm really intrigued by the Nano 7, but at $1,000, I'm unlikely to buy it... simply because I like this Smola so much.

The Smola in this review has more than 2x the heating capacity, but uses 220v because of that. So you’re very power-source limited there.
