Rubasse Micro 3kg
The Micro 3 kg is a commercial-grade solution for roasters who need precision, automation, and flexibility. A 6,000 W near infrared halogen source drives batches from 300 g up to 3 kg with ease. Charging, roasting, discharging, and cooling are fully automated through a 15.6 inch touchscreen. Energy use is engineered for efficiency, roughly 1 kWh per batch with minimal waste heat.
The optional Roast-Master Profile Replication System shines when you shift batch size. Load a saved profile, select the new weight on screen, and the system adapts roasting milestones and controls to match. You remove guesswork and keep results consistent across different runs.
Control can be extended further with modular add-ons such as digital pressure compensation, moisture detection, and drum thermometry. The compact chassis, about 130 x 45 x 95 cm and around 80 kg, balances power with practical placement. Ideal for growing roasteries that want scale without giving up craftsmanship.

Special Features
A "Flavor Guarantee": Near-Infrared Radiation Roasting
Direct, penetrating NIR energy drives clean caramelisation and even development, with high thermal efficiency and very stable heat delivery. Expect clarity at lighter roasts and rounded sweetness at medium roasts.
PRECISE ROAST PROFILE REPLICATION
The Micro platform records and replays heat, fan and drum, not just bean temperature, which tightens environmental stability and raises replay fidelity across batches.
LEVEL 4 ROAST-MASTER REPLICATION
Step up to Level 4 and the system replicates profiles while auto-adjusting by rate of rise (RoR), so you can run different batch weights against one curve and still land on target development. Ideal for production that needs fast, accurate reruns.
AIR PRESSURE COMPENSATION SYSTEM
Duct resistance and partial blockages can reduce exhaust flow, which skews flavour. The Micro’s compensation system senses the change and automatically corrects the exhaust to keep airflow stable, so batches remain consistent before and after cleaning.
ONE-TOUCH, END-TO-END AUTOMATION
Charge, roast, drop, cool and release in a single automated workflow. This shortens cycle times and reduces handling during busy production weeks.
ROAST MOISTURE PROFILING READY
Pair the roaster with Rubasse’s Exhaust Moisture Meter to visualise moisture release, verify the moment around first crack, and add a powerful process signal alongside temperature and rate of rise.
