The first roast that I did on this roaster was with 400 grams of Colombian Rainforest Santander from our friends at Single Origin. No particular reasons just a first batch to play with the machine. I didn’t bring my laptop to work so I logged my data on a piece of paper. Starting the roast at 400F was a bit high which resulted in some scorching of the beans. First crack at 7 and a half minutes in. Leaving the beans in the drum a bit longer dropping at 10 and a half, ensuring the end result ended up in the composter.
The crips temperature displays show roasting/bean temperature and air/environment temperature. The Fuji PXR controllers are using a max temperature setting of 500F and 750F respectively at what point the heater will be shut off. These temperature settings can be configured by the operator.
Activated buttons are surrounded by glowing led lighting using different colors for each button. The heater power control is set at 3 kW.
One would expect this window to be more useful for a gas roaster, but it actually shows the glowing coils when the heating elements receive sufficient power.
Heating the roaster to a higher than charge temperature and then turning off the power to let the roaster drop to the charge temperature.
The large cooling tray with rotating arms and a powerful fan very quickly cools down this 400 grams of first beans.
Slightly charred beans and too dark for my taste, these beans ended up in the composter.

A few days later, we roasted 1 kg of the same Colombian Rainforest Santander with much better results as you can see in the Artisan profile. The starting 3kW setting was a bit low which made the roast progress rather slow with a drop time of 15 minutes and 30 seconds. The result was a very nice medium-dark roast, a smooth and round bean, no chaff with the beans, and a very nice aroma.
All-in-all it was a great first impression and I am looking forward to my next roasts on this machine.
