Diedrich IR-24

• Commercial coffee roasting operations requiring batch processing.
• Speciality coffee shops and small-to-medium scale roasteries.
• Pilot plants for coffee blend development and quality control.
• Food processing facilities focused on roasted nut or grain production.

Typical batch capacity

For this model class, batch capacities commonly range from 12kg to 24kg.

Throughput

Units of this type typically offer a throughput of 60-100kg per hour, depending on batch size and roast profile.

Heating method

Diedrich IR series roasters utilise infrared burners, commonly fuelled by natural gas or LPG.

Power supply

Electrical requirements are typically single-phase, often around 230V, with amperage varying based on motor size and heating elements.

Footprint

This class of roaster requires a dedicated space, typically around 2m x 1.5m, plus clearance for maintenance and bean loading/unloading.

Control system

Modern units commonly feature advanced data logging and temperature control for bean and air temperatures.

Maintenance

Regular cleaning of the cyclone and general mechanical checks are standard for maintaining optimal performance.

• What is the advantage of infrared burners?

  Infrared burners typically provide a more consistent and even heat transfer to the coffee beans, which can lead to a more uniform roast and enhanced flavour development.

• Can this roaster handle different roast profiles?

• Is a data collection system important?

• What kind of ventilation is required?

• What does 'fully refurbished' mean for a used 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.
