Nucleus Link Sample Roaster

Nucleus Link Sample Roaster is a next-generation coffee roasting machine, meticulously engineered for precision, repeatability, and efficiency. Whether you’re a green coffee buyer, a small-batch roaster, or a quality control specialist, the Link is your key to unlocking the full potential of every coffee sample.

Key Features

• Hot Air Flow Roasting System: Advanced fluid-bed technology ensures uniform heat distribution, resulting in even development and exceptional clarity in the cup.
• Customizable Settings: Easily adjust bean temperature, airflow power, and development ratio to create your ideal roast profile.
• PID Automation: Delivers precise control based on advanced temperature feedback and pre-set roasting curves for consistent results.
• Open Bean Sensor: Accurately measures real-time bean and air temperature for better control and data integrity.
• Batch Size Flexibility: Optimized for 50–100 g batches of green coffee. Profiles automatically adapt airflow and heat to match batch size.
• Fast and Efficient: Typical roasting time of 8–10 minutes with an average cooling time of 4 minutes — perfect for sample evaluation or QC sessions.
• Extensive Profile Library: Preloaded with 41 roasting profiles (each with five development stages) and over 200 additional profiles available through Link Studio software.
• Handcrafted Quality: Designed and manufactured in New Zealand using premium-grade materials and components.

Precision Roasting

The Link guarantees consistent and repeatable results under any conditions. Its integrated Altitude Calibration, Density Roast Prediction, and DTR (Development Time Ratio) override systems automatically adjust airflow and heat based on altitude, bean density, and processing type. Developed in collaboration with Sam Corra, these profiles ensure an ideal balance between sweetness, body, and clarity.

Innovative Heating

The Link’s advanced convection system heats beans from the inside out, maintaining stable momentum and optimal heat transfer throughout the roast. Starting from ambient temperature enhances flavour clarity and freshness — an essential feature for accurate sample evaluation.

Portable Design

Built for professionals on the move, the Link combines robust engineering with full portability. It comes in a shock-proof and waterproof case, keeping your equipment protected during transport.

The kit includes:

• Dosing cup
• Density tube
• Coffee tray

Ready to roast immediately upon arrival — no tools or setup required.

Nucleus Studio and Link App

The Link works seamlessly with or without software. Using the Link App and Link Studio, you can:

• Calibrate according to altitude
• Automatically recommend profiles based on bean density and processing method
• Record, monitor, and replay roasts in real time
• Access hundreds of professional-grade profiles from the Nucleus library

With over 1000 supported profiles in the latest firmware, the Link offers unmatched flexibility and control.
