Petroncini 15Kg Capacity

• Small to medium-scale coffee roasting operations for cafes, micro-roasteries, and specialty coffee producers.
• Pilot plants for developing new roast profiles and coffee blends.
• Educational institutions for barista training and coffee science programmes.
• Artisan food production requiring precise thermal processing of beans or nuts.

Typical capacity

This unit is specified at 15kg per batch, suitable for small to medium production volumes.

Heat source

Units of this type commonly utilise gas (LPG or natural gas) for indirect heating, offering precise temperature control.

Roasting method

Indirect heat roasting is typical for this class, providing even heat distribution and reducing direct flame contact with beans.

Power supply

Beyond the gas supply, electrical power is typically required for motors, controls, and cooling fans, commonly single-phase or three-phase depending on the model.

Footprint

For a 15kg roaster, a footprint of approximately 1.5m x 1m is common, though this can vary with ancillaries like afterburners or destoners.

Construction material

Roasters are typically constructed from robust materials such as cast iron and stainless steel for durability and heat retention.

Cooling system

An integrated cooling tray and fan system is standard to rapidly cool roasted beans and prevent over-roasting.

• What does 'indirect heat' mean for coffee roasting?

  Indirect heat means the flame does not directly touch the coffee beans. Heat is transferred through a drum or heat exchanger, promoting more even roasting and reducing the risk of scorching.

• What are the implications of a roaster needing 'complete refurbishment'?

• Can this roaster be converted from LPG to natural gas?

• What ancillary equipment is typically needed with a coffee roaster?

• What maintenance is typically involved with a used coffee roaster?

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.
