Typical capacity

For this class of equipment, capacities typically range from 1kg to 12kg per batch.

Power supply

Roasters of this type commonly require a single-phase or three-phase electrical supply for motors and controls, alongside a gas supply (natural gas or propane) for the burner.

Heating method

Units like the K12 typically utilise direct flame gas heating for the roasting drum.

Footprint

The footprint for roasters in this category can vary, but typically requires a dedicated space of at least 1.5m x 1m, plus clearance for ventilation.

Construction material

Roasting equipment is commonly constructed from robust materials such as cast iron and stainless steel for durability and heat retention.

Control type

Older units often feature manual controls for drum speed, airflow, and burner intensity, with modern additions sometimes including digital temperature readouts.

• What is the typical lifespan of a well-maintained coffee roaster?
