Nucleus Link Coffee Roaster

The ultimate portable coffee roaster. Nucleus designed the Link to bring efficiency and precision into your workflow whether you are a green coffee buyer or a small batch roaster. The Nucleus Link allows you to fine-tune every aspect of your roast to match your exact specifications regardless of your location or process, thanks to its real-time data monitoring and roast control.

This portable roaster is ideal for roasting samples on the spot, allowing green coffee buyers to evaluate their acquisitions at their origin.

Precision roasting

The Nucleus Link guarantees a perfect roast no matter the conditions. You can take it to the farm and have it perform as splendidly as your trusty old roaster back in the roastery. The Link gives you full control of the roasting process with its Altitude Calibration, extensive roasting profile system developed by Sam Corra, customisable roasting profile, Density Roast Prediction, DTR override, and variable batch size.

Improved heating technology

Nucleus’ new innovative heating system heats the coffee beans from the inside out, allowing for a higher rate of heat and desired momentum in the roast profile. This way, you can start from ambient temperature to reduce unpleasant ‘gassy’ qualities and bring out the freshest flavours of your beans.

A Portable Roaster 

The robust construction of the Nucleus Link makes it hardy enough for travel. Plus it comes with a shock-proof and waterproof case that makes sure your portable roaster arrives at your destination in perfect condition. The kit also includes a dosing cup, density tube, and coffee tray provided so you can get right to work.
