Kaffelogic Nano 7e – your own roaster, right on the kitchen counter
You load in around 100 grams of green coffee, choose a profile, and around ten minutes later the aroma of freshly roasted beans rises to meet you – green turns to gold, right in front of you. The Kaffelogic Nano 7e is a highly precise convection roaster on the fluid-bed principle: hot airflow, measured bean temperature, automated process. Small enough for tight spaces, precise enough to serve as a sample roaster for roasteries, producers and green coffee traders.
Because an open bean sensor measures the temperature directly at the bean, and the roast follows a preset temperature curve via PID, your results stay consistent batch after batch. Through bean temperature and airflow strength you control the character of the roast – from super light to super dark. Included are 12 roast profiles with 60 roast levels each; you can create unlimited profiles of your own and share them simply as a file. How light or dark you roast is your decision – there's no right or wrong, what counts is that the coffee tastes good to you. That's our view, one of many.

Who the Nano 7e is for
For anyone who wants to roast their own coffee – at home with limited space just as much as in a roastery as a sample roaster. Thanks to ready-made profiles, getting started is easy, while the free software allows as deep an involvement as you like. The optional BOOST Kit extends the batch size range. If you'd rather source your beans already roasted, you'll find them in our Coffee Beans; the matching grinder for afterwards is in our Coffee Grinders.
See it in the showroom
You can see the Kaffelogic Nano 7e live at our showrooms – in Bern at Gerberngasse 44 and in Zürich Oerlikon at Hagenholzstrasse 50b. Financing is available.
Frequently asked questions
How much coffee does the Nano 7e roast per batch?
90 to 120 g of green coffee is recommended, typically in around 10 minutes, with about 4 minutes of cooling time. The optional BOOST Kit extends the batch size range.
How consistent are the roasts?
An open bean sensor measures the temperature directly at the bean, and the roast follows a preset temperature curve via PID – this ensures repeatable results.
Do I need the software?
No. The device runs independently with 12 included profiles. The free Kaffelogic Studio software (Windows, Mac, Linux) is for documenting, adjusting and creating your own profiles.
How quickly is the roaster delivered?
Order directly online: delivery across Switzerland and to Liechtenstein in 2–4 business days. Click & Collect available in Bern and Zürich Oerlikon.
