Typical batch capacity

For this class of equipment, batch capacities commonly range from 5kg to 7kg, suitable for small to medium production.

Power supply

Units of this type typically require a three-phase electrical supply, commonly 400V, 50Hz, with specific amperage varying by model.

Heating method

Roasters in this category often utilise gas (natural gas or LPG) for the main heating element, with electrical components for controls and motors.

Cooling

Integrated cooling trays with powerful fans are standard to rapidly cool roasted beans and prevent over-roasting.

Chaff collection

A separate husk (chaff) collector is typically included to remove the outer skin of the coffee beans during roasting, improving air flow and cleanliness.

Footprint

While specific dimensions vary, these roasters are generally compact, designed for spaces where floor area is a consideration.

Control system

Commonly features manual controls with analogue gauges, though some may have basic digital temperature readouts for drum and exhaust.

Used roasters are valued for their durability and cost effectiveness in food processing operations. Buyers typically prioritise even heat distribution, temperature control consistency, and robust construction when selecting secondhand units. Industry sentiment favours roasters from established manufacturers known for reliable performance. Key considerations include maintenance history, heating element condition, and capacity matching operational requirements. Well-maintained roasters often deliver dependable service across coffee roasting, nut processing, and other food applications, making them sound investments for processors seeking to minimise capital expenditure.
