Barth - Barth

Applications & Use Cases

• Evaluating small batches of green coffee beans to determine optimal roasting profiles.
• Quality control in coffee production facilities to ensure consistency of incoming bean lots.
• Research and development for new coffee blends and roast styles.
• Training new roasters on the principles of coffee roasting without large-scale bean consumption.
• Showcasing different roast levels to potential clients or for educational purposes.

Typical Specifications

Typical capacity

For a 3-barrel sample roaster, each barrel typically handles between 50g to 200g of green coffee per roast.

Power supply

Units of this type commonly require a standard single-phase electrical supply for motors and controls, typically 230V, 50Hz in the UK. Heating is often gas-fired.

Heating method

This class of sample roaster commonly uses natural gas or LPG for the roasting heat source, as indicated for this unit.

Footprint

Sample roasters are relatively compact, typically requiring a benchtop or small dedicated stand space, often less than 1 square metre.

Materials of construction

Roasting drums are typically made from cast iron or stainless steel for durability and heat retention, with other components often being steel.

Control type

Units of this vintage commonly feature manual controls for drum speed, airflow, and gas burner intensity, allowing for precise roast profile development.
