Kaffelogic Nano 7 | Home Coffee Roaster

Kaffelogic Nano 7 is a compact and highly precise convection (fluid-bed) coffee roaster, designed for both home users and professionals. It roasts 90–120 g of green coffee in about 10 minutes, offering exceptional consistency, automation, and control. Perfect for beginners with limited space, and for roasteries, producers, or green coffee traders seeking a reliable sample roaster.

Key Features

• Hot Air Flow Roasting System: Convection-based fluid-bed technology ensures even heat distribution for uniform bean development and excellent flavour clarity.
• Customizable Settings: Adjust bean temperature and airflow strength to achieve your ideal roast profile.
• PID Automation: Intelligent control based on temperature feedback and pre-set curves for consistent, repeatable roasts.
• Open Bean Sensor: Measures real-time bean temperature for precise and stable roast control.
• Batch Size: Optimized for 90–120 g of green coffee, ideal for cupping and profile testing.
• Fast and Efficient: Typical roasting time of 10 minutes and cooling time of 4 minutes — ready for multiple test batches per session.
• Profile Control: Includes 15 built-in profiles with up to 60 roast degree variations each, plus unlimited custom profiles.
• Handcrafted Quality: Designed and manufactured in New Zealand using premium-grade materials.

Precision Roasting

The Nano 7 delivers consistent and repeatable results, batch after batch. Its open bean temperature sensor allows for accurate real-time feedback, ensuring every roast follows the defined curve precisely. Combined with PID automation and Kaffelogic Studio software, users can analyse, replicate, and fine-tune their roasting profiles with scientific accuracy.

Innovative Heating

The roaster’s advanced convection system heats the beans from the inside out, maintaining stable heat momentum and even development. Starting from ambient temperature enhances flavour clarity and freshness - a crucial feature for cupping and sample evaluation.

Ready-to-Drink Roasts

Freshly roasted coffee normally requires a few days of degassing before brewing. However, thanks to Kaffelogic’s efficient hot-air system, it’s possible to create Ready-to-Drink roasts that can be consumed immediately after roasting. Kaffelogic provides specific profiles for this purpose, delivering vibrant, clean flavours straight from the roaster.

Free Software

The Kaffelogic Nano 7 can be used with or without software. The free Kaffelogic Studio program offers three key functions:

• Live recording of the roasting process
• Detailed analysis and documentation of roast data
• Creation, import, and modification of roasting profiles

The latest version of the Nano 7 connects directly via a USB-C ↔ USB-A cable, replacing the older USB stick method used in previous models.

Boost Kit (Optional Accessory)

The optional BOOST Kit expands the roasting capacity from 50 g to 200 g of green coffee, offering greater flexibility for testing or educational purposes. It’s ideal for users who want to increase their batch size without upgrading to a larger roaster.

Tips for Roasting with the Nano 7

The pre-programmed profiles make roasting incredibly simple. For best results:

• Select a profile based on the coffee’s processing type (washed, natural, honey).
• Adjust the roast level within the profile’s settings and compare results through cupping.
• Fine-tune airflow to balance sweetness, acidity, and aroma.
• Use Kaffelogic Studio to log roasts and achieve perfect repeatability.

Scope of Delivery

• Kaffelogic Nano 7 coffee roasting machine
• Chaff collector
• Dosing cup
• USB-C ↔ USB-A connection cable

In this updated version, roast logs and profiles are transferred directly via cable for faster, safer, and more reliable communication.

Kaffelogic Nano 7 vs Nucleus Link

Both are wonderful sample roasters, but designed for different needs:

• Kaffelogic Nano 7: Compact, affordable, and software-driven. Ideal for home users, trainers, and small roasteries focused on learning, cupping, and profile development.
• Nucleus Link: Professional-grade, field-ready roaster with built-in altitude calibration, density-based roast prediction, and over 1000 preloaded profiles for instant consistency and Q-grader-level precision.

The Nano 7 is your best starting point for exploring professional coffee roasting on a smaller scale, while the Nucleus Link represents the next step in high-end sample evaluation.
