Probat GN12

• Small to medium-scale coffee roasting operations, including artisan roasters and independent coffee shops.
• Speciality coffee producers requiring precise control over the roasting process.
• Pilot plants for coffee bean research and development.
• Businesses looking to expand into in-house coffee roasting.

Typical batch capacity

For this class of equipment, batch capacities commonly range from 6kg to 12kg of green coffee beans.

Heating method

Units of this type typically utilise gas (LPG or natural gas) for the roasting process, with electrical components for controls and motors.

Power supply

Electrical requirements commonly involve a single-phase supply, typically 230V, for motors and controls.

Footprint

A Probat GN12 typically requires a floor area of approximately 1.5m x 1m, plus clearance for operation and maintenance.

Cooling

Units commonly feature an integrated cooling tray to rapidly cool roasted beans, preventing over-roasting.

Chaff collection

Integrated or external cyclone systems are typically used for efficient chaff collection during the roasting process.

Control

While older models feature manual controls, refurbished units commonly include provisions for modern temperature probes and software integration for enhanced roast profiling.
