Giesen W6A

the verdict

the W6A handles 1-6 kg batches and works well for cafes adding roasting or small roasting companies building out their lineup. single-phase 230V power keeps installation simpler than three-phase machines, though you still need proper gas supply (3/8" connection, 17.5 kW heat input) and ventilation. the internal cyclone saves space and cost by eliminating external chaff collection. touchscreen gives you control over drum speed (36-51 Hz), underpressure (80-150 Pa), and temperature setpoints up to 250°C, which covers most roasting needs. at 485 kg the machine needs solid floor support but isn't impossible to place. sound level runs around 70 dB during operation. the 1-6 kg range gives you flexibility for small lots and testing without forcing you into tiny batches. main trade-off is that you're in premium pricing territory for this capacity, competing against established machines from Probat and others. build quality is solid and the controls are straightforward once you're familiar with them.
