Discover your unique roasting style and refine your craft with confidence, knowing the L100 Plus adapts effortlessly to your needs. Once you’ve achieved the perfect roast, AI-powered full automation ensures that same excellence, batch after batch.
AI First Crack Detection
Using artificial intelligence, the L100 Plus automatically detects the first crack during each roast. It then precisely monitors the ideal development time before automatically releasing the beans for the cooling process, ensuring consistent, professional-quality results every time.
Between-Batch Protocol
The L100 Plus is engineered by ROEST to eliminate unnecessary pauses in your production workflow. Each roaster is equipped with a dedicated cooling fan, allowing you to start the next batch immediately while the previous one cools. This enables continuous roasting of up to 1.2 kg of green coffee per hour without interruption. Additionally, the unique cooling tray sensor automatically detects when beans from the previous batch have been removed, ensuring seamless transitions between roasts.
