Kaffelogic Nano 7e

the verdict

the Nano 7e is a fluid-bed sample roaster built for consistency and compact operation. it uses pid control with Kaffelogic's proprietary look-ahead algorithm to hold temperature curves across batches, which works well for cupping protocols and qa workflows. the 90–120g batch window (expandable to 50–200g with the Boost Kit) fits standard sample roasting but feels restrictive if you want more range. fifteen onboard profiles handle most needs out of the box, and the Kaffelogic Studio software opens up full customization via usb-c. construction is powder-coated steel and aluminum, and the machine is not waterproof, so chaff cleanup requires care. roast times average ten minutes with a four-minute cooling cycle. this roaster suits roasteries doing regular sample evaluation, green buyers cupping lots, or home roasters who value automation and are comfortable working within structured batch limits. if you need broader batch flexibility or prefer drum roasting for sample work, other options may serve better.
