Probat GG12

• Small to medium-scale coffee roasting operations.
• Speciality coffee shops looking to roast their own beans.
• Pilot plants for coffee bean development and testing.
• Artisanal food producers requiring precise thermal processing of dry goods.

Typical batch capacity

For this class of equipment, batch capacities commonly range from 10kg to 15kg, with 12kg being typical for the GG12 model.

Heating method

Units of this type are typically gas-fired (LPG or Natural Gas) or electric. This specific unit has been converted to LPG.

Drum type

Probat roasters of this vintage commonly feature double-walled drums for consistent heat transfer and roast quality.

Control system
