- Typical capacity
- For this class of equipment, a 120kg roaster typically processes batches of up to 120 kilograms of green coffee or other suitable grains per roast cycle.
- Roast time
- Roast times commonly range from 12 to 20 minutes, depending on the desired roast profile and product.
- Power supply
- Units of this size commonly require a three-phase electrical supply, typically 400V, for motors and controls, in addition to the primary heat source.
- Heating source
- While this unit was adapted for LPG, Probat roasters of this type are commonly configured for natural gas, LPG, or sometimes fuel oil.
- Cooling system
- Integrated or separate cooling trays are standard for rapidly cooling roasted product, typically using ambient air drawn by a fan.
- Footprint
- A 120kg roaster typically requires a substantial industrial footprint, including space for the roaster, cooler, destoner, and associated exhaust systems.
- Construction material
- Roasting drums and critical contact parts are typically constructed from robust cast iron or stainless steel for durability and heat retention.
