Roast ready

Automated roasting in two steps

  • When you drop in the beans, the sample roaster follows your profile from start to finish with automated precision. Our AI solution identifies and registers First Crack and after reaching the ideal development time, beans are automatically released for a final cooling process.

  • As soon as the beans drop, the machine is ready for the next batch. After 90 seconds, your beans are cooled down and you can collect your first batch of coffee.
