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.
