▬ About the Nucleus Link sample roaster ▬▬▬ The Nucleus Link is a highly accurate convection roaster. It has been specifically designed as a sample roaster - in particular, it allows the same roast to be produced regardless of external conditions. This makes it perfect for communication between coffee growers, traders and roasters, and as a sample roaster for farm visits. The unit comes in a shockproof box and with accessories to determine the density of the beans. It also comes with an app that selects the appropriate settings for the machine based on the altitude, type and density of the beans. Thanks to its ease of use, the machine is also suitable for ambitious and quality-conscious home roasters.

Unlike traditional electric roasters, the Bullet roasters use induction to directly heat the drum. This induction heating allows for rapid and precise adjustments in heating power, as well as efficient heat transfer for fast and energy-efficient roasting. Another unique feature is the infrared sensor that allows the Aillio Bullets to measure the bean temperature without contact. This quick and precise measurement supports the development and execution of highly accurate roast profiles. With the Bullet, you can easily and finely adjust the heat transfer, airflow, and drum speed. The roaster is compatible with both Artisan and Aillio’s own user-friendly software, RoasTime, which allows for easy sharing of roast profiles with other users.
