--- title: Roasted coffee processing --- ### Roasted 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 ![roast processing](https://47580324.fs1.hubspotusercontent-na1.net/hub/47580324/hubfs/roast%20processing.png?width=300&name=roast%20processing.png) - [Sample Roaster](https://giesen.com/w6-series?hsLang=en) - [W1A/E](https://giesen.com/w6-series?hsLang=en) - [W6A/E](https://giesen.com/w6-series?hsLang=en) - [W15A/E](https://giesen.com/w6-series?hsLang=en) - [W30A/Pro](https://giesen.com/w6-series?hsLang=en) Giesen W6 series. ## Up to 24 kg / h.

These contaminants may not only damage grinders, brewers and other downstream equipment, but also pose safety risks to baristas or customers. By running the beans through a destoner, you catch and remove these unwanted items before they ever reach your brew line. In this way it protects your machinery, ensures product purity, and preserves the reputation of quality that specialty coffee demands.

The mixer ensures that different bean batches are blended thoroughly so that every blended batch of coffee is homogeneous. Because you can control rotation speed and blend duration, it offers consistency batch after batch.  The pellet press is used to transform the byproduct of roasting, coffee chaff, into compact, easy-to-handle pellets. This machine is designed to streamline waste management, reduce volume, and keep your facility cleaner and more efficient.
