Green coffee processing
A smooth roasting process starts with efficient green coffee handling. Giesen’s loading stations, transport systems, and silos create a clean, ergonomic, and fully controlled flow from intake to roasting—eliminating bottlenecks, reducing manual work, and keeping production consistent and uninterrupted.

Roasting
At the heart of the roasting process is one or more of our Giesen Pro-series roasters, available in various models to fit your capacity needs. Keep your roasting operation clean and compliant by significantly reducing flue gas emissions while fitting your specific setup and production goals.

Roasted coffee processing
A smooth post-roast process is essential to maintain quality and keep production moving efficiently. Our integrated transport, destoning, and mixing systems create a clean, controlled flow from roaster to roasted coffee storage. Removing impurities, improving blend consistency, and keeping your production fast, organized, and efficient.

Operational Excellence
From intake systems and roasters to destoners, silos, and conveyors, all Giesen equipment can be monitored and controlled seamlessly from a single interface. With complete visibility of the roasting process, operators can track performance, adjust settings, and coordinate production in real time.
