I am wondering if anyone is using these roasters - and what there experiences are, both with the roaster performance and after sales service from Sonofresco. I have made some pre-sales enquiries with Sonofresco, and to be honest, so far, they haven't exactly bowled me over... Thanks
Great machine, we use it for sample roasting. It produces a very different coffee than a traditional drum roaster for several reasons but it still does a nice job. You can't beat it for the price.
Can you elaborate on "very different" a little? Thanks
The Sonofresco starts the roast at room temperature & cycles hot air on and off throughout the roasting period. So the temperature fluctuates as the blower is cycling.
The roast time is also shorter than a traditional drum roaster; average of 9-11 minutes.
Finally the cooling cycle is longer & slower than a drum roaster because the coffee is cooled in the same container. The hot air must be forced out of the container & the temperature slowly comes back down to room temperature.
That being said, I generally find the coffee is not as smooth as a similar roast on the drum. Occasionally a coffee will turn out better on the Sonofresco than it does in the drum but for the most part people prefer the taste of the drum roaster slight over the fluid airbed.
I have had several coffees that simply did not turn out well on the Sonofresco but these are rare.
There are outstanding benefits to the Sonofresco though - consistency, automation, portability (farmers markets?!), ease of use.
Hope that helps!
I have been using 1 lb natural gas sonofresco for 6 years 400+ roasts . I have been very happy with it.I just bought a diedrich Ir3 . Now I must sell sonofresco. I would like to get $1,800
Never used one myself but know a few people that do use them. My first question to you is: How much volume are you expecting? 2 pounds at a time is a slow (and potentially miserable) way to do volume roasting.
Very small scale at this stage so no problem with the volume. Thanks everyone for your comments thus far. Any thoughts on their service?
Love the info shared. Both Coffee Crafters and Sonofresco are located in WA
I've been using a Sonofresco for about a year now. Very easy to roast, punch a few buttons and walk away. The result is a smooth, bright roast. I feel it has less acidity than a drum roasted coffee with a little less body and depth but a taste that I personally prefer. Support from Sonofresco has been outstanding.
I can suggest you Kafgar Commercial Coffee Roaster Machine. https://kafgarglobal.com/about-kafgar-coffee-roaster-machines/
