Double-layer cast-iron drum for stable heat distribution and consistent bean development.
Intuitive roasting panel with real-time temperature, airflow and profile control.
For uniform heat transfer to the beans in every batch you roast.
Thermal stability, long life of structure, minimal thermal expansion.
Uniform heat transfer to the beans, ensures minimization of scoring.
The C30 is intended for production plans built around 10–30 kg batches and up to 120 kg/h. It is relevant when a 15 kg machine would require too many cycles, but the operation does not regularly need 60 kg batches. Confirm that the larger minimum batch, gas infrastructure, room, and ventilation fit the facility.
The C30 handles 10–30 kg per batch, with a roasting time of approximately 10–15 minutes and output up to 120 kg/h. Plan production from the normal batch and roast profile, then allow operational time for loading, discharge, cooling, and preparation for the next cycle.
The C30 uses propane or natural gas and is not available with electric heating. Its electrical systems are rated at 220 V, 50–60 Hz, and 4 kW. Tell us the installation country and selected gas so we can confirm gas pressure, electrical services, connectors, and local requirements.
The C30 requires 540 m³/h roasting exhaust through a nominal 200 mm connection and 800 m³/h cooling exhaust through a nominal 175 mm connection. Wall openings and both duct routes must be designed for local technical and safety requirements.
The C30 handles 10–30 kg batches and up to 120 kg/h. The C60 handles 30–60 kg and up to 240 kg/h. Choose C30 when you need smaller routine batches or lower ventilation demand. Choose C60 when regular production justifies larger batches, twice the rated hourly output, and substantially higher exhaust airflow.
