We developed a computerised roast control system that mimics what an artisanal hands-on roaster does, right down to making precise adjustments at specific times during the roast. As a result there are a raft of groundbreaking technical innovations built into the Kaffelogic roast control system. The PID control loop uses predictive rate of rise (not just temperature) which gives the Nano 7 unprecedented ability to follow a profile curve. Add to this the ability to make subtle changes to PID gain parameters, apply power boosts, and use power profiling at pre-defined times during the roast and you have the most nuanced roast control system in the world.

The Kaffelogic Nano 7 is an air roaster. Getting the air speed right is critical to flavour development and this is something that the Kaffelogic excels at. The fan speed control system is so precise that it is possible to keep the beans in a state of transitional fluidisation - just enough air to circulate the beans and ensure an even roast with good chaff removal, yet not too much air to dry out the beans and cool the bean surface during exothermy. The result: an extremely clean roast with good depth of flavour.

Roasting produces around a thousand different flavour chemicals, and the chemistry doesn't stop when the roaster stops. The chemical balance keeps on getting better both during and after roasting until it reaches peak flavour. Then, after a few days, flavour starts to fade. The Kaffelogic roast control system is so precise that it is possible to influence the rate of different chemical reactions during the roast, and thereby alter the timing of peak flavour. This means coffee can be roasted ready to drink, or, by choosing the appropriate profile, roasted ready to rest for three days before drinking. We supply both ready to drink and three day resting profiles.

The Nano 7 is designed for daily use. It remembers the last roast settings used, so when you emerge for the day only to discover you are out of coffee, just add another scoop of green beans. We figured you might be operating it in a caffeine deprived state so we made it as fail safe as possible. So wake up, pour those beans in, press start, and smell the coffee.

We want your grandchildren to inherit your Kaffelogic in perfect working order. That's why we use only robust components, why every part is replaceable, and why the roaster can be disassembled and reassembled with ordinary tools. We believe that the best way to be sustainable is to build with the future in mind and to honour the right to repair.

No more plastic valve, foil lined or laminated bags when you buy coffee beans. You can buy green beans in paper bags or reusable cotton bags. That's a lot of packaging no longer going to landfill.
