giesen coffee roasters giesen w30a
the W30A moves into serious production territory with 6-30 kg batch capacity, aimed at roasters supplying multiple wholesale accounts or larger cafe operations. the 6 kg minimum is reasonable for this size machine, letting you handle smaller lots without jumping down to a different roaster. you get the same touchscreen profile logging system as smaller Giesen models, with control over drum speed, underpressure, and temperature setpoints. gas-fired drum provides consistent heat when properly set up and maintained. at this capacity you're making a significant investment in floor space, gas infrastructure, and ventilation. the machine competes directly with established European manufacturers in the 30 kg range, where build quality and control precision matter more as batch sizes increase. Giesen's Dutch manufacturing is solid but you should compare carefully against Probat, Loring, and others at this level. works best for roasters with established demand who need reliable capacity and can support the infrastructure requirements.
